Background: Candida species, especially Candida albicans , cause oral candidiasis, also known as oral thrush. It affects the elderly, newborns, patients under antibiotics, chemotherapeutic agents, and patients with weaker immune systems. Although successful, traditional antifungal medications are available, they may have negative effects and do not prevent recurrence. Conventional antifungal medications have a restricted range of effectiveness; hence, the need for a novel antifungal agent arises. Chitosan, a natural polymer made from chitin found in crustaceans, kills fungal cells by damaging membranes. Excellent biocompatibility and biodegradability make it a promising medical material. Probiotics, live bacteria, compete with pathogenic microbes for adhesion sites and nutrients, produce antimicrobials such as lactic acid, hydrogen peroxide, and bacteriocins, and modulate the host's immunological response. Adding probiotics to chitosan nanoparticles (CSNPs) boosts their antifungal activity against Candida species and increases their stability and transport to the infection site., Methods: The antifungal activity was evaluated through in vitro experiments utilizing Candida strains that are significant to oral candidiasis. Different concentrations of CSNPs and formulations loaded with probiotics were examined to assess their effectiveness. The antifungal properties were assessed using microbiological assays, specifically agar diffusion and minimum inhibitory concentration (MIC)., Results: The study demonstrated a notable fungicidal impact of CSNPs combined with probiotics against oral candidiasis. Furthermore, the MIC values were lower for the probiotic-loaded CSNPs than for chitosan alone or probiotics alone., Conclusion: The combination of CSNPs and probiotics shows potential in effectively combating oral candidiasis by inhibiting fungal growth. This novel method offers a promising strategy for creating therapeutic treatments for oral candidiasis by utilizing the combined benefits of chitosan and probiotics to combat fungal infections effectively., Competing Interests: Human subjects: All authors have confirmed that this study did not involve human participants or tissue.

Introduction:   Candida albicans , a common fungal pathogen, is often associated with oral infections such as denture stomatitis. Dental varnishes, especially those incorporating antimicrobial agents, have shown promise in preventing C. albicans colonization. This study investigates the antifungal efficacy of a dental varnish incorporating green-synthesized silver nanoparticles (AgNPs) using Ocimum gratissimum and Ocimum tenuiflorum extracts., Materials and Methods: AgNPs were synthesized via a green synthesis method using Ocimum extracts. The AgNPs were then incorporated into a dental varnish. The antifungal efficacy of the AgNP-incorporated varnish was evaluated against C. albicans using various assays, including agar well diffusion, time-kill curve, protein leakage, and cytoplasmic leakage analyses., Results: The AgNP-incorporated dental varnish demonstrated significant antifungal activity against C. albicans . The agar well diffusion assay showed a dose-dependent increase in the zone of inhibition, with the highest concentration (100 µg/mL) achieving a zone of 23 mm. The time-kill curve assay indicated a concentration-dependent reduction in colony-forming units (CFU) of C. albicans , with the highest concentration resulting in a CFU reduction to below 10 3  within five hours. Both protein and cytoplasmic leakage analyses confirmed membrane disruption, showing increased optical density readings at higher concentrations of AgNPs., Discussion: The results suggest that the antifungal activity of the AgNP-incorporated dental varnish is mediated through multiple mechanisms, including membrane disruption, increased permeability leading to protein and cytoplasmic leakage, and possibly the generation of reactive oxygen species (ROS). The varnish's efficacy was comparable to that of commercial antifungal dental varnishes, highlighting its potential as a viable alternative in dental applications., Conclusion: Green-synthesized AgNPs, when incorporated into dental varnish, exhibit potent antifungal activity against C. albicans . The study demonstrates that this approach can effectively disrupt fungal cells, suggesting its potential use in preventing and treating oral fungal infections. Future research should explore the in vivo efficacy, safety, and long-term stability of AgNPs in dental varnish formulations., Competing Interests: Human subjects: All authors have confirmed that this study did not involve human participants or tissue.

Introduction Acne vulgaris is a common skin problem caused by inflammation of the sebaceous glands and hair follicles as a result of hormonal fluctuations, bacteria, and overproduction of oil. The plant Peltophorum pterocarpum ( P. pterocarpum ) has been investigated for possible medical uses. Its anti-inflammatory, antibacterial, and antioxidant qualities are well recognised, and they may be applied to treat several diseases. This study investigates the plant's phytochemicals for their effectiveness in treating acne. Methods The Indian Medicinal Plants, Phytochemistry and Therapeutics (IMPPAT) database was utilised to extract the phytochemicals from P. pterocarpum . The absorption, distribution, metabolism, and excretion (ADME) analysis was conducted using the online tool SwissADME. The SwissTargetPrediction tool determines the potential targets of these phytochemicals. Targets for acne have been identified using the Open Targets Platform database. The common targets of P. pterocarpum and acne were identified using the Venn diagram drawing tool Venny 2.1.0, and a protein-protein interaction (PPI) network was built using the Search Tool for the Retrieval of Interacting Genes/Proteins (STRING) database. Following that, hub genes were identified by Cytoscape 3.10.2. The web tool ShinyGO 0.80 has enabled simpler evaluation of enrichment analysis for these hub genes. Results Five genes were shown to be key targets because they are directly engaged in the relaxin signalling pathway by pathway analysis: epidermal growth factor receptor (EGFR) and various matrix metalloproteinases (MMPs) (MMP1, MMP2, MMP9, and MMP13). The phytochemicals found in P. pterocarpum , including quercetin, rhamnetin, hirsutidin, and (+)-leucocyanidin, target these key genes. Conclusion This study highlights the potential of P. pterocarpum as a multi-target therapeutic agent for acne vulgaris. By targeting key genes in the relaxin signalling pathway, the phytochemicals from P. pterocarpum present a promising approach for acne management., Competing Interests: Human subjects: All authors have confirmed that this study did not involve human participants or tissue.

Introduction Nanotechnology is the study of manipulating matter at the atomic scale involving particles smaller than 100 nm. Silver nanoparticles (AgNPs) are gaining popularity across diverse sectors including medical, food, healthcare, consumer goods, and industrial fields due to their distinctive physical and chemical characteristics. The eco-friendly synthesis of AgNPs offers a straightforward, cost-effective, and environmentally benign method devoid of hazardous chemicals. Methodology Eighty milliliters (mL) of silver nitrate mixed with 20 mL of Azadirachta indica and Syzygium aromaticum plant extract underwent two days of magnetic stirring for AgNP synthesis. Characterization was done via ultraviolet-visible (UV-vis)-spectroscopy (300-700 nm), and antimicrobial properties, which were checked with Enterococcus faecalis , were assessed using the agar-well diffusion method. Results The change in color and peak observed in the UV-vis spectrum confirmed the successful synthesis of AgNPs. Both neem and clove extract-mediated synthesis of AgNPs exhibited antibacterial activity against E. faecalis . However, neem extract synthesized AgNPs displayed a larger inhibitory zone diameter and lower minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values compared to those synthesized using clove extract. Conclusion Incorporating neem and clove extracts in AgNP synthesis offers a practical, eco-friendly, and cost-efficient method with notable efficacy. These AgNPs exhibit antibacterial activity against E. faecalis , suggesting their viability as potent antibacterial agents for addressing oral pathogens. Their sustainable synthesis underscores a promising avenue for developing effective antimicrobial solutions in oral healthcare., Competing Interests: Human subjects: All authors have confirmed that this study did not involve human participants or tissue.

Background Herbal medicine has gathered increasing attention in contemporary healthcare practices, offering natural remedies for a wide range of ailments such as skin diseases, liver disorders, bronchitis, and asthma. Among the plethora of medicinal plants, Croton bonplandianum , commonly known as "Ban Tulsi," holds significant medicinal value owing to its diverse pharmacological properties. This study investigated the cytotoxicity, embryotoxicity, antidiabetic, and anticariogenic effects of an ethanolic extract derived from C. bonplandianum . The research objectives were to explore the preparation of an ethanolic extract of C. bonplandianum and employ a multifaceted approach by evaluating its cytotoxicity, embryotoxicity, anticariogenic, and antidiabetic potentials. Materials and methods In this study, the β-glucosidase inhibitory and the α-amylase inhibitory assays were utilized to evaluate the antidiabetic activity of the  C. bonplandianum ethanolic extract. The in vitro cytotoxicity activity was assessed by using the brine shrimp lethality assay (BSLA), and embryotoxicity was evaluated using zebrafish embryos and larvae. Through the agar well diffusion method and the time-kill curve analysis, the anticariogenic activity was evaluated. Results In α-amylase and β-glucosidase inhibitory assays, the ethanolic extract of  C. bonplandianum showed potent antidiabetic properties, near those of standard acarbose. The cytotoxicity evaluation using the BSLA showed less toxicity. The anticariogenic activity of the ethanolic extract of C. bonplandianum  was assessed by comparing the standard (Amoxyrite) in terms of its zone of inhibition against oral pathogens such as  Streptococcus mutans and Lactobacillus species (spp.). The antibacterial efficiency was validated using a time-kill curve assay in which the study depends on the concentration of the bacterial pathogenic organisms, namely, Lactobacillus spp. and S. mutans . In embryotoxicity evaluation, there were no morphological malformations in zebrafish larvae or embryos when exposed to high concentrations of C. bonplandianum ethanolic extract. Conclusion The ethanolic extract of  C. bonplandianum exhibited promising antidiabetic and anticariogenic effects, supporting its conventional usage in alternative medicine. The outcomes of these research analyses suggest the plant potential as a natural source of compounds with bioactive qualities and can be utilized in the healthcare and pharmaceutical industries., Competing Interests: Human subjects: All authors have confirmed that this study did not involve human participants or tissue.

Background Selenium nanoparticles (SeNPs) are one of the metal nanoparticles that have been widely utilized for their anti-microbial, anti-oxidant, anti-inflammatory activities, and other biomedical applications. Tridax procumbens (TP) stem extract is a promising herb species rich in flavonoids, tannins, alkaloids, phytosterols, and hydroxycinnamates, which play a major role in wound healing applications.  Aim The study aims to synthesize SeNPs using TP stem extract , characterizations, and its biomedical applications. Materials and methods SeNPs were synthesized using TP stem extract. The green synthesis of SeNPs was confirmed by ultraviolet-visible (UV-vis) spectra analysis. The synthesized SeNPs were characterized using Fourier-transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The agar well diffusion method was utilized to evaluate the anti-bacterial properties of the green synthesized SeNPs using TP stem extract. The anti-oxidant effect of SeNPs was tested using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, ferric-reducing anti-oxidant power assay (FRAP), and hydroxyl radical scavenging assay (H₂O₂). The anti-inflammatory effect was investigated using the bovine serum albumin assay and egg albumin denaturation method, and the cytotoxic effect of the green synthesized SeNPs was tested using the brine shrimp lethality (BSL) assay. Results The green synthesis of SeNPs was confirmed using different types of analysis techniques. The characterizations were done by UV-visible spectroscopy analysis, exhibiting a maximum peak at the range of 330 nm. SEM analysis revealed the shape of the nanoparticle to be hexagonal. The agar well diffusion method exhibited the anti-bacterial efficacy of SeNPs against wound microorganisms with a zone of inhibition of 14.6 mm for Escherichia coli ( E. coli ), 15.8 mm for Staphylococcus aureus ( S. aureus ), and 15.4 mm for Pseudomonas aeruginosa ( P. aeruginosa ). The TP stem-mediated SeNPs showed potential effects in anti-oxidant, anti-inflammatory, and cytotoxic activity, which shows very little toxicity. Conclusion Overall, the green synthesis of TP-stem-mediated SeNPs has great potential in biomedical applications. Thus, the synthesized SeNPs exhibit significant anti-bacterial efficacy against wound pathogens. The TP stem-mediated SeNPs showed potential effects in anti-oxidant, anti-inflammatory, and cytotoxic activity, which shows low toxicity. Furthermore, the green-synthesized SeNPs can be utilized in therapeutic management., Competing Interests: Human subjects: All authors have confirmed that this study did not involve human participants or tissue.

Background Glass ionomer cement (GIC) serves as a crucial biomaterial in dental restoration, offering applications in filling, lining, and adhesive procedures. Nevertheless, its mechanical properties often fall short, particularly in regions subjected to considerable stress. To address this issue, zirconia nanoparticles are incorporated at specific levels. Aim To assess the antimicrobial efficacy and compressive resilience of GIC modified with zirconia nanoparticles synthesized through green synthesis methods. Material and methods Zirconia nanoparticles were synthesized via a green method utilizing aloe vera extract in solvent form. These nanoparticles were then mixed into GIC at different concentration levels. Group I incorporated zirconia nanoparticles at a concentration of 3%, Group II at 5%, and Group III at 10%, while Group IV was the control, consisting of traditional GIC. Following that, samples were prepared and underwent characterization through various analytical techniques. The ability to inhibit microbial growth and the compressive resilience of the groups were examined. Microbial inhibition against the bacterial strains was assessed through minimum inhibitory concentration (MIC), and the ability to withstand compression was gauged by measuring the maximum force the specimen could endure before fracturing. Data underwent analysis with Statistical Package for the Social Sciences (IBM SPSS Statistics for Windows, IBM Corp., Version 24.0, Armonk, NY). Repeated measures of analysis of variance (ANOVA) were utilized to gauge average MIC values and compressive strength. Following this, Tukey's post hoc test was employed for pairwise comparisons. Results The findings indicated, incorporating zirconia nanoparticles into GIC led to an improvement in its antimicrobial effectiveness, with a noticeable enhancement observed as the weight percent (% wt) of the additive increased. This improvement was notably noticeable in its effectiveness against Streptococcus mutans and Lactobacillus , exceeding that of the control with a noteworthy distinction. Furthermore, there were significant enhancements in compressive strength, in Group I (180.48 ± 1.02), Group II (191.25 ± 0.52), and Group III (197.52 ± 0.75), compared to Group IV (167.22 ± 1.235), with significant disparities (p < 0.05). Conclusion The research illustrates that introducing green-synthesized zirconia nanoparticles into GIC leads to heightened bactericidal potency and compressive resilience when contrasted with the control group (Group IV). Notably, the highest concentration of 10% demonstrated the most favourable antimicrobial attributes alongside enhanced strength. Consequently, integrating green-synthesized zirconia nanoparticles into GIC holds potential as a proficient material. In future studies, there should be an exploration of molecular chemistry and bonding mechanisms to enhance our comprehension of its capabilities., Competing Interests: Human subjects: All authors have confirmed that this study did not involve human participants or tissue.

Introduction: The present study aimed to evaluate and compare the anti-inflammatory effects of two oral rinse formulations, a commercial oral rinse and an  Ocimum tenuiflorum and Ocimum gratissimum  (nanocomposites, NCs) oral rinse, using in vitro assays commonly employed to assess anti-inflammatory activity., Materials and Methods: The anti-inflammatory potential of the oral rinse formulations was assessed using bovine serum albumin (BSA) denaturation, egg albumin denaturation, and membrane stabilization assays. Diclofenac sodium was used as a reference standard in all assays. The inhibition percentages of BSA denaturation and egg albumin denaturation assays, as well as membrane stabilization effects, were measured at various concentrations of the oral rinse formulations., Results: Both the commercial oral rinse and the  Ocimum tenuiflorum and Ocimum gratissimum  oral rinse demonstrated significant inhibition of BSA denaturation, indicating their anti-inflammatory potential. The  Ocimum tenuiflorum and Ocimum gratissimum (NCs) oral rinse consistently showed higher inhibition percentages than the commercial oral rinse, suggesting stronger anti-inflammatory effects in this assay. In the egg albumin denaturation assay, both formulations exhibited inhibition of protein denaturation, with the  Ocimum tenuiflorum and Ocimum gratissimum  (NCs) oral rinse showing comparable or slightly higher inhibition percentages. The membrane stabilization assay further supported the anti-inflammatory properties of both formulations, with the  Ocimum tenuiflorum and Ocimum gratissimum (NCs) oral rinse demonstrating efficacy comparable to diclofenac sodium., Discussion: The results suggest that  Ocimum tenuiflorum and Ocimum gratissimum (NCs) oral rinse may possess stronger anti-inflammatory effects compared to commercial oral rinse, as evidenced by higher inhibition percentages in the BSA denaturation assay. Both formulations showed promising anti-inflammatory activity in the egg albumin denaturation and membrane stabilization assays, indicating their potential for mitigating inflammation., Conclusion: The  Ocimum tenuiflorum and Ocimum gratissimum (NCs) oral rinse exhibits significant anti-inflammatory effects in vitro, potentially surpassing the efficacy of the commercial oral rinse. Further studies are needed to explore the clinical implications of these findings and to validate the anti-inflammatory properties of the  Ocimum tenuiflorum and Ocimum gratissimum (NCs) oral rinse in vivo., Competing Interests: Human subjects: All authors have confirmed that this study did not involve human participants or tissue.

Introduction:  Dental caries has become a substantial global health burden, and many techniques have been used in dentistry to protect the tooth from decay. Brassica oleracea is a green cruciferous vegetable with a good source of vitamins C, K and E, which are also effective antibiotics and antioxidants. These characteristics will shield the oral cavity from pathogenic onslaught and can be considered during the formulation of antimicrobial mouthwash, toothpaste, or dental sealants., Materials and Methods:   B.  oleracea extract was prepared by heating and condensing the red and green cabbage. Both extracts were assessed for antimicrobial activity (antibacterial and antifungal activities) and cytotoxicity. After incubation, the zone of inhibition was calculated for antibacterial activity and the number of live nauplii for cytotoxicity.  Results: The extract from red cabbage was found to have more effective antibacterial properties than that from green cabbage. The red B. oleracea extract formed the highest zone of inhibition against Candida albicans (20 mm), followed by Enterococcus faecalis (15 mm) and Streptococcus mutans (9 mm).

Background Glass ionomer cement (GIC) plays a vital role in dental restorative procedures, serving purposes such as filling, luting, and adhesion. However, its inadequate mechanical properties pose challenges, especially in areas experiencing significant stress. To overcome this limitation, nanohydroxyapatite (nHA), known for its bioactive phosphate content, is added to the GIC at specific concentrations to improve its properties. Aim  We aim to evaluate the antimicrobial property and compressive strength of green-mediated nHA-incorporated GIC. Material and methods Green synthesis of hydroxyapatite nanoparticles was prepared using Moringa oleifera extract in a solvent form and eggshell waste served as the calcium source. These nHA powders were then integrated into the GIC at varying concentrations (3%, 5%, and 10%) designated as Group I, Group II, and Group III, respectively, while Group IV (control) consisted of conventional GIC. Specimens were fabricated and subjected to chemical structure analysis through Fourier transform infrared spectroscopy (FTIR), energy dispersive X-ray (EDX), and scanning electron microscopy (SEM). The antimicrobial activity and compressive strength of all groups were investigated. The antimicrobial activity against Streptococcus mutans and Lactobacillus was evaluated through the minimum inhibitory concentration (MIC) test, while compressive strength was evaluated by measuring the maximum force endured by the specimen before fracturing. Data analysis utilized IBM SPSS Statistics software, employing repeated measures ANOVA to determine mean MIC values and compressive strength, with Tukey's posthoc test for pairwise comparisons. Results The results of the study showed that the antimicrobial efficacy of nHA GIC improved with increasing weight percent (% wt) of the additive, exhibiting significantly enhanced activity against Streptococcus mutans and Lactobacillus compared to the control group (Group IV) with statistical significance (p < 0.05). Moreover, the compressive strength exhibited notable enhancements in the modified groups, including Group I (172.55 ± 0.76), Group II (178.16 ± 0.760), and Group III (182.45 ± 0.950), when compared to the control (162.46 ± 1.606), with statistically significant differences (p < 0.05). Conclusion The study demonstrates that the incorporation of green-mediated nHA-containing GIC results in superior antimicrobial efficacy and compressive strength compared to the control group (Group IV). In particular, the highest concentration of nHA-modified GIC (10%) exhibited the most favorable antimicrobial properties along with increased strength. Therefore, utilizing green-mediated nHA in the GIC shows promise as an effective restorative material. Future investigations should delve into the molecular chemistry and bonding mechanisms to further explore its potential., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Ilancheran et al.)

Introduction Effective root canal cleaning and sealing are essential for a successful endodontic procedure. For the purpose of disinfecting root canals, both herbal and non-herbal medications are recommended. This study aimed to analyze the antimicrobial and cytotoxic properties of biosynthesized silver nanoparticles (AgNPs) synthesized from Azadirachta indica /neem and chemically synthesized AgNPs from trisodium citrate (TSC) against oral pathogens to be further used as an irrigant in endodontic treatment. Materials and methods To synthesize  A. indica  AgNPs, powdered fresh A. indica  leaves were weighed, added to double distilled water, heated for 30 minutes, and then combined with silver nitrate solution. TSC was also used to create TSC AgNPs. X-ray diffraction (XRD), scanning electron microscopy (SEM), ocular observation, and the ultraviolet-visible light (UV-vis) spectrum were used to characterize the AgNPs. Studies were conducted on the extract's characteristics, including its cytotoxicity and antibacterial activity. Results The hue shift and peak on the UV-vis spectrophotometer were signs that AgNPs were forming. The XRD pattern showed that the sample included crystalline AgNPs, mostly spherical ones. By using SEM, the presence of AgNPs was also verified. AgNPs that were synthesized showed antimicrobial efficacy against Enterococcus   faecalis . Compared to chemically synthesized AgNPs, A. indica AgNPs showed lower minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values, a bigger zone of inhibition (ZOI), and less cytotoxic action. Conclusion This study demonstrates the minimal cytotoxicity and antibacterial activity of A. indica AgNPs against E. faecalis . This suggests that they might also be employed as root canal cleaners. Before experimenting with animals or cell lines in clinical trials for endodontic treatment, further research should be done., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Chandran et al.)

Background Dental caries stands out as a significant global infectious disease, with oral diseases posing substantial health concerns primarily due to bacterial, fungal, and yeast infections. Kalanchoe pinnata demonstrates antimicrobial, anticancer, antiparasitic, and hepatoprotective properties, with applications in various ailments. Piper longum exhibits potent antimicrobial effects against bacterial and viral pathogens due to the bioactive compounds within the plant. This study aims to assess the antimicrobial efficacy of P. longum and K. pinnata formulation against oral pathogens and evaluate its other biomedical potential. Methodology The agar well diffusion method was employed to assess the antimicrobial activity of the formulation containing P. longum and K. pinnata against oral pathogens. The protein leakage assay was employed to assess the ability of the prepared formulation to cause protein release from oral pathogens. The other biomedical potentials of the prepared formulation including cytotoxic effects, antioxidant, and anti-inflammatory properties were investigated using in vitro assays. Results The prepared P. longum and K. pinnata formulation demonstrated significant antimicrobial activity against tested oral pathogens, with inhibition zones observed for Staphylococcus aureus (32 mm), Streptococcus mutans (22 mm), and Candida albicans (12 mm). However, no inhibition was observed on Enterococcus faecalis at the highest concentration of 100 μL. Additionally, the formulation demonstrated significant antioxidant activity with percentages of 89.22%, 84.4%, and 86.93% in 2,2-diphenyl-1-picrylhydrazyl (DPPH), hydrogen peroxide (H 2 O 2 ), and ferric (Fe 3+ )-reducing antioxidant power assays, respectively, at the maximum concentration of 50 μL. Furthermore, the formulation exhibited potential anti-inflammatory activity, as evidenced by 79% inhibition in bovine serum albumin (BSA) denaturation assay and 77% inhibition in egg albumin (EA) denaturation assay at the highest concentration of 50 μL. Additionally, the formulation displayed low cytotoxic effects, even at the highest concentration of 80 μL. Conclusion K. pinnata  and  P. longum  formulation demonstrated potential antimicrobial efficacy against oral pathogens and exhibited diverse therapeutic potentials. Thus, the developed formulation could be used as a potential alternative for pharmaceutical drugs against oral pathogens., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Anandan et al.)

A calcaneal tuberosity avulsion fracture constitutes a sub-group of calcaneal fractures and it poses a high risk of soft tissue compromise, necessitating urgent reduction and fixation. This fracture was commonly treated with screw fixation, and fixation failure associated with this method has been reported in the literature. In light of this, we tested and compared the strength of two-screw (2S) versus three-screw (3S) fixations, where the third screw was fixed from the posterior calcaneal tuberosity towards the anterior process in addition to the two parallel screws. Synthetic calcaneum models were tested with an Instron machine to measure the maximum tensile load and stiffness. The mean maximum tensile loads for 3S and 2S were 455.8 N (SD = 47.4) and 341.0 N (SD = 30.9), respectively, and the difference was statistically significant. The mean stiffnesses for 3S and 2S were 29.2 N/mm (SD = 1.8) and 29.7 N/mm (SD = 2.0), but this difference did not reach statistical significance. Based on our findings, the added third screw increased the pull-out strength and can be inserted percutaneously to minimize soft tissue compromise., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Wan et al.)

Background Glass ionomer cement (GIC) demonstrates biocompatibility and fluoride ion release, indicating their potential to inhibit a wide range of bacteria, although this remains uncertain. Lemongrass and neem are recognized for their potent antimicrobial activity against numerous pathogenic microorganisms. The objective of the study is to evaluate the antimicrobial effectiveness and compressive strength of GIC modified with neem and lemongrass. Methodology Lemongrass and neem were incorporated into conventional GIC at varying concentrations. Group I - neem-modified GIC (0.5%, 1%, 2%), group II - lemongrass-modified GIC (0.5%, 1%, 2%), and group III (non-modified GIC as a control group). The disk-shaped specimens were then compared to unmodified GIC (control). Antimicrobial effectiveness was assessed using the minimal inhibitory concentration (MIC) assay against Streptococcus mutans and Lactobacillus . Compressive strength was assessed using a Universal Testing Machine, with a crosshead speed set to 0.5 mm per minute. Statistical analysis was conducted with a significance level set at p < 0.05. Results Neem modification displayed superior antimicrobial effectiveness against both Streptococcus mutans and Lactobacillus at all concentrations when compared to the control, with 2% showing the least mean value of 0.262. In contrast, lemongrass modification exhibited a significant difference in effectiveness against Streptococcus mutans but no difference against Lactobacillus . Neem modification demonstrated superior performance compared to lemongrass (p < 0.05). Both modified groups showed no significant impact on compressive strength. Conclusions Neem-modified GIC demonstrated the highest antimicrobial efficacy against Streptococcus mutans and Lactobacillus without altering its compressive strength. This suggests its potential as a promising alternative material in restorative dentistry.

Background and objective Glass ionomer cement (GIC), also known as polyalkenoate cement, has been extensively used in dentistry for both luting and restorative purposes. Despite being the first choice for aesthetic restorations due to their chemical bonding ability to teeth, GICs have faced challenges such as low mechanical properties, abrasion resistance, and sensitivity to moisture, leading to the search for improved materials.  This study aims to assess the effects of thermocycling on the compressive, flexural strength, and microhardness of green-mediated nanocomposite-modified GIC in comparison to traditional GIC. Methodology Green-mediated nanoparticles, consisting of chitosan, titanium, zirconia, and hydroxyapatite (Ch-Ti-Zr-HA), were synthesized using a one-pot synthesis technique to form nanocomposites. These nanocomposites were then incorporated into GIC specimens in varying concentrations (3%, 5%, and 10%), denoted as Group I, Group II, and Group III, respectively. Group IV served as the control, consisting of conventional GIC. To assess the performance of the novel restorative materials over an extended period, compressive strength, flexural strength, and microhardness were measured before and after thermocycling using a universal material testing machine. Furthermore, scanning electron microscopy (SEM) analysis was carried out following the thermocycling process. The collected data were subjected to statistical analysis through one-way analysis of variance (ANOVA) and paired t-tests. Results  The findings demonstrated that, in comparison to the control group, both the mean compressive strength and flexural strength, as well as hardness, were notably higher for the 10% and 5% nanocomposite-modified GIC specimens before and after thermocycling ( P  < 0.05). Notably, there was no notable difference observed between the 5% and 10% concentrations ( P > 0.05). These results suggest that incorporating green-mediated nanocomposites (Ch-Ti-Zr-HA) modified GIC at either 5% or 10% concentration levels leads to improved mechanical properties, indicating their potential as promising alternatives in dental restorative materials. Conclusions Based on our findings, it can be inferred that the 10% and 5% concentrations of green-mediated (Ch-Ti-Zr-HA) modified GIC exhibit superior compressive and flexural strength compared to conventional GIC. Additionally, analysis of the scanning electron microscope (SEM) morphology revealed that green-mediated GIC displays smoother surface characteristics in contrast to conventional GIC. These results underscore the potential advantages of utilizing green-mediated nanocomposite-modified GIC in dental applications, suggesting enhanced mechanical properties and surface quality over conventional., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Ravi et al.)

Background Glass ionomer cement (GIC) is widely recognized for its self-adhesive characteristics and biocompatibility, making it commonly used as a restorative material. However, challenges related to limited antibacterial effectiveness and relatively low mechanical properties have hindered its widespread clinical use. Clove and ginger are recognized for their potent antimicrobial activity against numerous pathogenic microorganisms. The present study aims to enhance the clinical applicability of GIC by modifying it with clove and ginger extract. Aim The objective of the study is to assess the antimicrobial effectiveness and compressive strength of GIC modified with ginger and clove extract. Materials and methods Ginger and clove extracts were prepared and incorporated into conventional GIC at three concentrations for each, creating ginger-modified GIC groups (Group A, Group B, and Group C) and clove-modified GIC groups (Group D, Group E, and Group F), with Group G as the control (conventional GIC without modification). The antimicrobial assessment was conducted on disc-shaped GIC specimens (3.0 mm height x 6.0 mm diameter) prepared using molds. Bacterial strains were used to evaluate antimicrobial properties, with minimum inhibitory concentration (MIC) assays conducted at intervals of one to four hours for both modified and unmodified groups. Compressive strength specimens were prepared using cylindrical molds (6.0 mm height × 4.0 mm diameter), according to the ISO (International Organization for Standardization) guidelines. The evaluation was conducted using a Zwick universal testing machine (ElectroPuls® E3000, Instron, Bangalore, India), with the highest force at the point of specimen fracture recorded to determine compressive strength. Statistical analysis was conducted utilizing a one-way analysis of variance (ANOVA) alongside Tukey's post hoc test, with a significance threshold set at p < 0.01. Results The antimicrobial effectiveness of clove and ginger-modified GIC was assessed through a MIC assay, revealing a statistically significant improvement in antimicrobial potency against Streptococcus mutans and Lactobacillus within the modified groups compared to the control group (p < 0.01). Increased extract concentration correlated with enhanced antimicrobial activity. Clove-modified GIC exhibited superior antimicrobial efficacy compared to ginger extract. Compressive strength was higher in clove-modified GIC groups (p < 0.01), with Group F showing a maximum value of 175.88 MPa, while other modified groups demonstrated similar results to the control, with a value of 166.81 MPa (p > 0.01). Conclusion The study concludes that both clove-modified GIC and ginger-modified GIC exhibited antimicrobial activity against Streptococcus mutans and Lactobacillus species. The antimicrobial activity was notably higher in clove-modified GIC compared to ginger-modified GIC. Additionally, the compressive strength of clove-modified GIC surpassed all other groups. Thus, clove-modified GIC emerges as a promising restorative material for addressing recurrent caries. Future investigation is necessary to assess the long-term durability of the material., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Paulraj et al.)

The anti-inflammatory activity was assessed using the Bovine serum albumin (BSA) denaturation assay, egg albumin (EA) denaturation assay, and membrane stabilization assays. The antimicrobial activity was analyzed using the agar well diffusion technique and the time-kill curve assay. Results In DPPH and H 2 O 2 tests, the DMSO extract of A. calamus showed significant antioxidant activity, near that of standard ascorbic acid. The FRAP assay demonstrated a correlation between the dose and the activity of reducing ferric ions. The A. calamus  DMSO extract exhibited significant anti-inflammatory properties in BSA and EA denaturation assays, similar to the standard diclofenac sodium. The anti-inflammatory potential of the A. calamus DMSO extract was further confirmed through the membrane stabilization assay. The DMSO extract of A. calamus exhibited a significant inhibition zone against the pathogens Streptococcus mutans and Pseudomonas aeruginosa during the antimicrobial evaluation, surpassing the efficacy of the standard antibiotic. The time-kill curve assay validated the antibacterial efficacy, which was dependent on the concentration. Conclusion The A. calamus DMSO extract exhibited promising antioxidant, anti-inflammatory, and antimicrobial properties, supporting its traditional use in alternative medicine. The findings suggest its potential as a natural resource of compounds with bioactive properties for use in pharmaceutical and nutraceutical applications., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Haran et al.)

The assessment of compressive strength was conducted following ISO 9917-1:2007 standards, and the recorded values represent the maximum force the specimen could withstand before fracturing. Results The antimicrobial effectiveness against Streptococcus mutans and Lactobacillus exhibited a notable increase in all modified specimens compared to the control group, with a significance level of p<0.05. Additionally, significant improvements in compressive strength were observed in group III (183.49±2.99) when compared to the remaining groups. The higher concentrations of the plant extract resulted in superior outcomes. Conclusion Therefore, the incorporation of Acacia nilotica into GIC shows promising potential as a restorative material. These investigations can provide valuable insights into the material's performance and durability, contributing to its potential application in dental restorations.

Background:   Enterococcus faecalis  biofilm formation within root canals poses a challenging problem in endodontics, often leading to treatment failure. To combat this issue, nanotechnology offers a promising avenue for enhancing antimicrobial efficacy. This study explores the potential synergistic effects of combining nanoscale silica particles with conventional antibiotics, including doxycycline, metronidazole, and ciprofloxacin, against E. faecalis biofilms. The unique characteristics of silica nanoparticles, such as their increased reactivity and ability to be functionalized with other compounds, make them ideal candidates for augmenting antibiotic efficacy. This research investigates the antimicrobial properties of these silica-based combinations and their potential to eliminate or inhibit E. faecalis biofilms more effectively than conventional treatments.  Methodology: The methods involved the preparation of nanostructured silica particles and their combination with doxycycline, Flagyl, and ciprofloxacin at subinhibitory concentrations. These combinations were then tested against E. faecalis biofilms using the agar well diffusion technique., Results: Preliminary results suggested that the synergistic interactions between silica nanoparticles and antibiotics can significantly enhance antimicrobial efficacy. The combined treatment exhibited superior inhibitory effects on E. faecalis compared to antibiotics or silica nanoparticles alone ( P  < 0.05).  Conclusions: This study sheds light on the potential of nanoscale silica-based combinations to address the challenges posed by E. faecalis biofilms in endodontics. Understanding the mechanisms of synergy between nanoparticles and antibiotics can pave the way for the development of more effective and targeted strategies for root canal disinfection, ultimately improving the success rates of endodontic treatments., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Hameed et al.)

Background Discoloration affects glass ionomer cement (GIC) color stability due to its brittle nature and microporosity. To counter this, incorporating alternative materials is essential for maintaining color stability. Aim This study aims to determine the color stability and gloss of GIC modified with bioactive chitosan, titanium, zirconia, and hydroxyapatite nanoparticles before and after artificial aging. Materials and methods  The study was conducted at Saveetha Research Centre, Saveetha Dental College and Hospitals, Saveetha Institute of Medical and Technical Sciences, Saveetha University, located in Chennai, India. Green-mediated chitosan, titanium, zirconia, and hydroxyapatite (Ch-Ti-Zr-HA) nanoparticles were synthesized using the one-pot synthesis technique. Forty-eight disc-shaped specimens were prepared by incorporating the obtained nanoparticles (nanocomposite) into the GIC, with a diameter of 5 mm and thickness of 2 mm. The specimens were prepared in different concentrations (3%, 5%, and 10%) designated as group I, group II, and group III, respectively. Group IV, serving as the control, consisted of conventional GIC without any modifications. Following preparation, scanning electron microscopy (SEM) and energy-dispersive X-ray (EDX) microanalysis confirmed sample elements, and the specimens were submerged in distilled water for a duration of 24 hours prior to the commencement of testing. Subsequently, the specimens underwent artificial aging (thermocycling), between temperatures of 5°C and 55°C, for a total of 30,000 cycles, with a 30-second dwell time. Color change and gloss characteristics were assessed both after 24 hours and following thermocycling using a spectrophotometer and glossometer, respectively. The average color change parameter (ΔE) was measured using Adobe Photoshop. The data obtained were subjected to statistical analysis using an unpaired t-test. Results Significant color stability variations were observed post thermocycling (P = 0.001). Group 2 (5%) exhibited minimal delta E difference (0.508 ± 0.105), indicating superior color stability, while group 4 (control) had maximum difference (1.15 ± 0.187), indicating lower stability. Gloss tests confirmed GIC's polishability, where there were significant differences among all the groups. Conclusion It can be concluded that 5% nanoparticle-modified GIC has better color stability and gloss than conventional GIC. Further studies are needed to analyze the color stability and gloss through dentifrices and other beverages., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, E et al.)

Introduction: The diversity of oral epithelial cells offers potential viral infection sites. The lower level of ACE2 inhibitors in women's blood renders them more resistant to coronavirus disease 2019 (COVID-19). In order to determine the effect of COVID-19 vaccination on female hormones, salivary levels of total antibody, immunoglobulin G (IgG), and cortisol were measured in young and elderly women., Methods: Saliva samples from 88 participants were collected and subjected to ELISA for detecting total antibody, IgG, and cortisol., Results: Women who were infected with COVID-19 and who completed two doses of vaccination had more IgG antibodies when compared to the uninfected individuals/single-dose/non-vaccinated individuals. The cortisol levels in post-menopausal women were higher than those in women with normal menstrual cycles, and the difference was statistically significant (P-value 0.00). The increased cortisol levels were well correlated with increased levels of IgG antibodies which was statistically significant (Spearman rho P value 0.00) Conclusions: COVID variants will continue to mutate and evolve as long as the epidemic persists. The higher cortisol and IgG antibodies produced by female hormones protect them from COVID-19 infection., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Panneer Selvam et al.)

Background Wound infections caused by pathogens present a considerable global health challenge, resulting in extended healing durations, elevated healthcare expenses, and potential fatalities. Conventional approaches to managing wound pathogens have limitations such as antibiotic resistance, toxicity and allergic reactions. Consequently, there is a rising interest in exploring alternative strategies for preventing and treating wound infections. Titanium dioxide nanoparticles (TiO 2 NPs) have gained attention for their potential in wound healing, attributed to their distinctive properties, including antimicrobial and anti-inflammatory capabilities. Methods TiO 2 NPs synthesized through Euphorbia tirucalli were examined for their antibacterial potential against wound pathogens, using the Kirby-Bauer agar-well diffusion method and time-kill curve assay. Furthermore, the cytotoxic effect of the synthesized nanoparticles was evaluated through a brine shrimp lethality assay. Results Green-synthesized TiO2NPs demonstrated potent antimicrobial activity against tested wound pathogens, displaying a zone of inhibition against Pseudomonas aeruginosa (11 mm) and Escherichia coli (10 mm) at the highest concentration of 100 μg/mL. In the time-kill curve assay, the prepared TiO 2 NPs showed significant bactericidal activity against Pseudomonas aeruginosa followed by Escherichia coli . In the brine shrimp lethality assay, at the lowest concentration of 5 μg/mL of the prepared nanoparticles, 100% of the nauplii remained alive after 48 hours. Conclusion The results indicate that TiO 2 NPs synthesized using Euphorbia tirucalli extract exhibit potent antimicrobial activity against the tested wound pathogens. Moreover, the prepared nanoparticles exhibit lower toxicity, suggesting their potential use as an alternative to commercially available synthetic drugs., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Natarajan Sankar et al.)

Introduction Nanotechnology holds considerable importance in biomedical and dental applications. Nanoparticles synthesized using green synthesis methods with herbal formulations offer various benefits to humans. Zinc oxide nanoparticles (ZnONPs), being semiconductors, exhibit potent antibacterial properties. Notably, treatments utilizing lemongrass and mint ensure potentially lower toxicity and antibacterial qualities for oral infections. The goal of the study is to prepare a mouthwash mediated by ZnONPs and assess its cytotoxic potential and antibacterial efficacy. Materials and methods A lemongrass and mint formulation was used in the synthesis of ZnONPs, and the mouthwash was prepared using the synthesized nanoparticles. The produced ZnONPs were tested for their antimicrobial activity using agar well diffusion technique against oral pathogens, and the ZnONPs-mediated mouthwash was evaluated for its cytotoxic effect using the brine shrimp lethality assay and compared to commercial mouthwash.  Results The green-synthesized ZnONPs were initially confirmed using a UV-visible spectrophotometer and exhibited a maximum peak at 362 nm. The antimicrobial activity was tested for the synthesized ZnONPs against oral pathogens, which showed a maximum zone of inhibition of 22 mm in  Enterococcus faecalis  and 23 mm in  Candida albicans , as estimated by the agar well diffusion technique. Additionally, ZnONPs-based herbal mouthwash demonstrated lower cytotoxicity than the commercial mouthwash in the brine shrimp lethality assay. Conclusion In the current study, lemongrass and mint-mediated ZnONPs demonstrated an effective antibacterial activity against E. faecalis and antifungal activity against C. albicans . Furthermore, the cytotoxic effect tested using the brine shrimp lethality assay for ZnONPs-mediated mouthwash demonstrated lower toxicity as compared to the commercial mouthwash. This suggests that the green-synthesized ZnONPs-based mouthwash could be used as an alternative to synthetic mouthwash., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Shanmugam et al.)

Background: Glass ionomer cement (GIC) restorations are commonly used in primary dentition, due to their aesthetic appeal, self-adhesive nature, and biocompatibility. However, the material's limited antibacterial activity and inadequate mechanical strength highlight the necessity for modifying the material., Aim: The study aims to evaluate and compare the antimicrobial potency and compressive strength of GIC-incorporated Miswak extract with that of conventional GIC., Materials and Methods: After obtaining the Miswak extract, a modified GIC was formulated by combining the extract with the conventional GIC powder and liquid components, in three different ratios (Powder: Extract and Liquid), Group I (2:1:1), Group II (3:1:2), Group III (3:2:1), and the Group IV as control, which consist of unmodified/conventional GIC. To evaluate and compare the antibacterial efficacy of the modified and unmodified GIC, standard strains of Streptococcus mutans and Lactobacillus were utilized. For each group, the minimal inhibitory concentration (MIC) assay was tested. For the evaluation of compressive strength, cylindrical moulds were utilized in compliance with ISO 9917-1:2007 standards and tested using the universal testing machine (Instron, ElectroPuls®, Bangalore, IND). The highest force exerted at the point of specimen fracture was recorded to calculate the compressive strength values in MPa. The data obtained were analyzed using the Statistical Package for the Social Sciences (IBM SPSS Statistics for Windows, IBM Corp., Version 24.0, Armonk, NY) software. The statistical analysis was conducted utilizing repeated measures of analysis of variance (ANOVA) to calculate the mean MIC values and compressive strength, with pairwise comparisons assessed using Tukey's post hoc test., Results: The results proved that the antimicrobial properties of Miswak containing GIC performed better against S. mutans and Lactobacillus with a statistically significant difference when compared with group IV (p<0.05), it has been found that an increase in the concentration of extract increased the antimicrobial potency. Significant results were obtained in compressive strength where Group II (41.49±3.6) and Group III (15.23±4.96) proved to be weaker than the control (62.69±2.58), while Group I showed no differences from the control group (p>0.05)., Conclusion: It can be concluded that Group I was found to be better in terms of both antimicrobial properties and compressive strength, where no significant difference in compressive strength was identified when comparing Group I with Group IV. Thus, the overall study depicts that a lesser concentration of extract can be the best option in terms of good antimicrobial properties without altering its strength. Hence, the Miswak containing GIC could be a promising restorative material; further studies should include considering intraoral variables such as masticatory stress, moisture levels and in-vivo tests of this combination., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Devi et al.)

Agar well diffusion test was conducted to assess the antimicrobial activity of these compounds against Staphylococcus aureus (S. aureus), Streptococcus mutans (S. mutans), Enterococcus faecalis (E. faecalis), and Candida albicans (C. albicans). Results: The vitamin K2 + nHAP nanocomposite exhibited antimicrobial activity against all tested microorganisms, with E. faecalis showing the highest sensitivity (25 mm zone of inhibition at 100 µL concentration). The K2 + Chito + nHAP nanocomposite demonstrated potent antimicrobial activity with C. albicans displaying the highest sensitivity (28 mm zone of inhibition at 100 µL concentration). Pure vitamin K2 showed limited antimicrobial activity, vitamin K2 combined with chitosan exhibited significant susceptibility to C. albicans , resulting in a substantial inhibition zone of 24 mm diameter at a concentration of 100 µL., Conclusion: The synergistic effects of vitamin K2 with nHAP and chitosan highlight the potential of these nanocomposites for biomedical applications. These findings contribute to the development of effective nanocomposites to address antimicrobial resistance and improve infection control in various biomedical fields., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Duraisamy et al.)

Background The aim of this study was to evaluate and compare the anti-inflammatory properties of silver nanoparticles (AgNPs) and zinc oxide nanoparticles (ZnONPs) that were synthesized utilizing African tulsi and black tulsi herbal formulations. The anti-inflammatory activity was assessed by the utilization of bovine serum albumin (BSA) denaturation and egg albumin denaturation tests. In addition, a membrane stabilization experiment was performed to evaluate their efficacy as anti-inflammatory drugs . Methods This study was conducted at Saveetha Dental College and Hospitals, Saveetha Institute of Medical and Technical Sciences (SIMATS), Saveetha University, Chennai, India. AgNPs and ZnONPs were synthesized using Ocimum tenuiflorum (African tulsi) and  Ocimum gratissimum (black tulsi) extracts. The BSA denaturation assay involved mixing serum albumin with different nanoparticle concentrations (10-50 µg/mL) and measuring absorbance at 660 nm. The egg albumin denaturation assay followed a similar procedure. The membrane stabilization assay utilized red blood cells and spectrophotometric measurements at 540 nm. Results In the BSA denaturation assay, AgNPs and ZnONPs showed concentration-dependent inhibition of protein denaturation. While these nanoparticles exhibited anti-inflammatory potential, diclofenac sodium consistently displayed slightly stronger inhibition. In the egg albumin denaturation assay, AgNPs and ZnONPs inhibited protein denaturation at various concentrations. Their anti-inflammatory effects were comparable to the standard drug, diclofenac sodium. In the membrane stabilization assay, both nanoparticle types demonstrated concentration-dependent membrane stabilization effects. Diclofenac sodium exhibited slightly stronger membrane stabilization. Conclusions AgNPs and ZnONPs synthesized using  Ocimum tenuiflorum and Ocimum gratissimum (African tulsi and black tulsi) possess anti-inflammatory potential, as demonstrated by their inhibition of protein denaturation and membrane stabilization. While these nanoparticles show promise as anti-inflammatory agents, further research is needed to explore their clinical applications and safety profiles., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Varghese et al.)

Background: Glass ionomer cements are commonly utilized in dental restorations due to their biocompatibility, strong chemical bond with dental tissues, and ability to resist tooth decay. However, their effectiveness can be compromised by the presence of persistent cavity-causing microorganisms. Therefore, it is essential to consider incorporating antibacterial agents into these restorative materials. Swertia chirayita (S. chirayita) and Terminalia arjuna (T. arjuna) are well-known for their rich composition of phytochemicals that can potentially inhibit the growth of bacteria. Hence, the current research is focused on modifying glass ionomer cement with Chirayita and T. arjuna extracts to enhance its antibacterial properties., Aim: This research aims to determine the antimicrobial efficacy and compressive strength of glass ionomer cement modified with Chirayita and T. arjuna extracts., Methodology: Plant extracts were prepared from both Chirayita and T. arjuna. The powder and liquid components of conventional glass ionomer cement (GIC) were mixed, followed by adding these extracts at three different concentrations. To assess antimicrobial properties, typical strains of Streptococcus mutans and Lactobacillus were employed to test both the modified GIC and unmodified GIC (used as a control). For Chirayita and T. arjuna-modified GIC, minimum inhibitory concentration (MIC) assays were conducted at three different concentrations. MIC was assessed at various time intervals ranging from 1 to 4 hours for modified and unmodified groups. Moreover, compressive strength was measured using cylindrical molds. The highest force exerted at the point of specimen fracture was recorded to calculate the compressive strength values in megapascal (MPa)., Results: The antimicrobial efficiency of Chirata and T. arjuna-modified GIC was evaluated using a MIC assay, indicating a statistically significant enhancement in antimicrobial potency against S. mutans and Lactobacillus within the modified groups in contrast to the control group (p<0.05). However, there were no notable changes in compressive strength when comparing the control group to the modified groups (p>0.05)., Conclusion: The antimicrobial effectiveness against S. mutans was observed to be greater in both T. arjuna and Chirayita-modified GIC. In the case of Lactobacillus, Chirayita-modified GIC exhibited more pronounced antimicrobial properties compared to T. arjuna. Importantly, both extracts did not alter the compressive strength of Conventional (unmodified) GIC. Hence, Chirayita-modified GIC appears to be a promising restorative material for combatting recurrent caries. Additional investigation is required to assess the material's stability over an extended period., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Devi et al.)

Background The interest in natural remedies is increasing rapidly as they can serve as alternatives to synthetic drugs and reduce their potential side effects. Current research is focused on examining the antioxidant and anti-inflammatory characteristics of a combination of  Cucumis sativus  and C itrus macroptera  extract in an in-vitro context. The combination of citrus, cucumber, and glycerol extract could serve as an effective alternative to synthetic antioxidants and anti-inflammatory drugs and lower the side effects of the available synthetic drugs. This extract can be used to treat potentially malignant oral disorders like oral leukoplakia, oral submucous fibrosis, and oral lichen planus, which are attributed to its antioxidant properties. Aim To evaluate the anti-inflammatory and antioxidant activity of formulation of  C. sativus ,  C. macroptera , and glycerol extract. Materials and methods The cucumber and citrus fruits were separated, cleaned, and dried. The cucumber was then peeled, its seeds cleaned, and the pulp cut into pieces. Using a laboratory mortar and pestle, a 5 ml extract was prepared. The citrus fruit was cut in half, its seeds were removed, and a 5 ml extract was prepared from their pulp only. These two extracts were combined to form a 10 ml extract solution with 8 ml of glycerol. The extracts were combined, shaken for 24 hours, filtered, and stored at 4°C. Assays like the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay, Hydrogen Peroxide (H2O2) assay, Bovine serum albumin (BSA) assay, and Egg albumin (EA) denaturation assay were performed to assess their anti-inflammatory and antioxidant properties. Results The antioxidant and anti-inflammatory properties of the extract showed comparable activity (percentage of inhibition: 76% in BSA and EA assays; 90% in DPPH and H2O2 assays) to that of the standard values (percentage of inhibition: 78% in BSA and EA assays; 92% in DPPH and H2O2 assays) at concentrations 30, 40, and 50 µl in the BSA assay, EA assay, DPPH, and H2O2 assay. The maximum concentration at which the antioxidant and anti-inflammatory effects were appreciable was 50 µl in all assays.  Conclusion This study concluded that the combination of cucumber, citrus, and glycerol extract could serve as an effective alternative to synthetic antioxidants and anti-inflammatory drugs currently available. These extracts can provide a promising solution in the field of drug development for treating lesions caused by free radicals and oxidative stress in the oral cavity., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Amani et al.)

Introduction Herbal mouthwashes were designed and prepared using essential oils from phytotherapeutic plants, containing active agents such as catechins, tannins, and sterols. Quercetin is one of the most abundant natural flavonoids predominantly found in foods including fruits, and vegetables. It has wide biological effects such as antioxidant, anti-aging, anti-inflammatory, probiotic, and metabolic modulation activities. Research has pointed toward its anti-microbial efficacy and bio-compatibility. Materials and methods A sample of commercially available Himalaya Hiora mouthwash (control) and 0.02 mg of Quercetin (test sample) that is sold commercially were procured. Next, 0.01 grams of sodium lauryl sulfate (SLS), which serves as the foaming agent, 0.001 grams of preservative (sodium methylparaben), and 0.3 grams of sucrose, the sweetening agent, were added to the test sample to formulate the mouthwash. We added 0.5 milliliters of the prepared Quercetin solution to the mixture. The effectiveness of the Quercetin mouthwash formulation as an antimicrobial was evaluated using the Agar-Well Diffusion Method against five oral pathogens and compared to the Hiora mouthwash. Results On quantifying the zone of inhibition, it was observed that at 100 μL of concentration, Staphylococcus aureus shows maximum inhibition rate, i.e., 15 mm when compared to commercially available herbal mouthwash (Himalaya Hiora). Thus, from the results obtained, we found that when concentration increases there is a significant zone of inhibition shown by oral pathogens. Conclusion Quercetin mouthwash formulation has proven to have a good antimicrobial effect when compared to standard mouthwash. The effective antimicrobial activity suggests its potential use as an adjuvant chemical plaque control modality. Further clinical trials would pave the way for its use as a routine or therapeutic antimicrobial agent., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, L et al.)

Introduction Type 2 diabetes mellitus and its associated health complications represent a significant public health issue due to its wide prevalence. The primary disadvantages of current oral anti-diabetic drugs are their limited bio-availability and their quick release, which necessitates more frequent dosing. Similar limitations are encountered when using natural products for the management of type 2 diabetes. Consequently, nanoparticles have been developed with the goal of enhancing the physicochemical stability of the drugs, thereby improving their bio-availability. In view of the given background, the present study aimed to explore the efficacy of strontium nanoparticles derived from pomegranate peel extract in managing type 2 diabetes mellitus. Materials and methods The aqueous extract of pomegranate peel was prepared using standard protocol and the strontium nanoparticles were prepared by green synthesis method using pomegranate peel extract. The prepared aqueous extract of pomegranate peel and the nanoparticles were assessed for their inhibitory potential against α-amylase and α-glucosidase enzymes activity by 3,5-dinitrosalicylic acid (DNSA) and p-nitro-phenyl-ɑ-D glucopyranoside (p-NPG) assays, respectively. Results The pomegranate peel-mediated strontium nanoparticles (PP-Sr NPs) and standard acarbose were assessed for their inhibitory effect against diabetic enzymes, α-amylase, and α-glucosidase at different concentrations range of 5-160 μg/ml. The results showed that PP-Sr NPs exhibited a maximum inhibition of 79.28% and 76.17% against α-amylase and α-glucosidase respectively at the highest concentration of 160 μg/ml. Acarbose showed a maximum inhibition of 88.02% and 84.47% against α-amylase and α-glucosidase respectively at 160 μg/ml. The inhibitory effect of the PP-Sr NPs and standard acarbose was found to be concentration-dependent. Conclusion From the results, it is concluded that the PP-Sr NPs may be useful for decreasing postprandial glucose levels. Further studies using in vitro cell lines and in vivo diabetic models may substantiate the antidiabetic potential of PP-Sr NPs., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Royapuram Parthasarathy et al.)

Background Antioxidants are vital in reducing oxidative stress, a key factor in the pathogenesis of many chronic diseases, including cancer, cardiovascular disease, and neurodegenerative disorders. The aim of our study is to analyze and compare the oxidative potential of biosynthesized selenium, strontium, and zinc oxide nanoparticles (NPs). Materials and methods Selenium nanoparticles (SeNPs) were synthesized using 20 mM of sodium selenite as the precursor and 1 g each of Cymbopogon citratus and Syzygium aromaticum as reducing and stabilizing agents. Strontium nanoparticles (SrNPs) were synthesized with 30 mM of strontium chloride as the precursor and 1 g of Acacia nilotica as a reducing and stabilizing agent. Zinc oxide nanoparticles (ZnONPs) were synthesized using 30 mM of zinc nitrate as the precursor and 1 g each of Cuminum cyminum and Syzygium aromaticum as reducing and stabilizing agents. Selenium, strontium, and zinc oxide nanoparticles were characterized using Fourier-transform infrared spectroscopy (FT-IR) analysis. The antioxidant activity of biogenically synthesized strontium, selenium and zinc oxide nanoparticles was examined using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay (DPPH assay) and hydroxyl radical scavenging assay (H 2 O 2 assay). Results The FT-IR spectra of selenium nanoparticles revealed a peak at 3327.990 cm -1 , strontium nanoparticles at 3332.331 cm -1 , and zinc oxide nanoparticles at 3216.346 cm -1 . The significant results for the green-synthesized selenium, strontium, and zinc oxide nanoparticles were observed in antioxidant assays. The results from the DPPH assay show that at the highest concentration of 50 µL, SrNPs exhibited 90.12 % inhibition, SeNPs displayed 90.12% inhibition, and ZnONPs showed 89.55% inhibition. In the H 2 O 2 assay, at the highest concentration of 50 µL, SrNPs showed 87.43% inhibition, SeNPs displayed 85.11% inhibition, and ZnONPs exhibited 84.66% inhibition. SrNPs demonstrated a higher percentage of inhibition in both the DPPH and H 2 O 2 assays. Maximum inhibitory activity was observed at the highest concentration. However, the prepared nanoparticles showed a slightly lower percentage of inhibition when compared to the standard. Conclusion Strontium nanoparticles synthesized based on Acacia nilotica demonstrated excellent antioxidant activity compared to the synthesized selenium and zinc oxide nanoparticles. Therefore, the study suggests that the produced strontium nanoparticles can serve as an antioxidant agent, owing to their remarkable free radical scavenging activity., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Shanmugam et al.)
