Statement of the Problem: It is challenging to perform a pulpectomy procedure in primary tooth because of its physiological root resorption and variation in root morphology. Working length measurement is considered to be one of the critical steps, as it determines the extent of obturation and apical seal., Purpose: To compare the accuracy of electronic apex locator (EAL) and digital radiography (DR) for working length determination in primary teeth., Materials and Method: In this systematic review, electronic databases and grey literature were searched from 1st January 2005 to 1 st January 2023 for randomized control trial, non- randomized control trial, in vitro studies, ex vivo studies that compared accuracy of EAL and DR in primary teeth. Two reviewers independently identified studies, retrieved data, and assessed risk of bias using the revised and validated MINORS (methodological index for non-randomized studies) criteria., Results: Ten studies were included in qualitative analysis. Seven out of ten studies showed low risk of bias whereas other three studies showed high risk of bias. In view of methodological heterogeneity of the findings, a meta-analysis was not conducted., Conclusion: Available evidence suggests a moderate quality of evidence in this systematic review. Analyzing the ten studies included in this systematic review, the majority of studies showed statistically insignificant difference between EAL and DR. However, EAL was closer to actual WL as compared to DR. Based on the evidence that is currently available; EAL can be considered as an alternative for working length measurement in primary teeth., Competing Interests: The authors declare that they have no conflict of interest., (Copyright: © Journal of Dentistry.)

Background: Pit and fissure sealants are the most commonly used preventive measure against caries in permanent molars. Advancements in dental materials have led to the development of hydrophilic sealants. However, their clinical efficacy must be evaluated and compared with that of conventional hydrophobic sealants., Objectives: This study aimed to clinically evaluate and compare the retention, marginal adaptation and marginal discoloration of hydrophilic and hydrophobic pit and fissure sealants over a 12-month follow-up period., Material and Methods: The study was a split-mouth, double-blind, randomized controlled trial. A sample size calculation was performed, and 120 first permanent molars (60 in each group) were selected for inclusion in the study. According to the split-mouth design, the sample was randomly divided into 2 groups. Group A was treated with a hydrophilic sealant (UltraSeal® XT Hydro), while Group B was treated with a hydrophobic sealant (Conseal F). The sealants in both groups were applied in accordance with the manufacturer's instructions by a single operator. The sealants were evaluated clinically using visual and tactile methods by 2 independent examiners who were blinded to the procedure in accordance with the modified United States Public Health Service (USPHS) clinical rating system at placement and at 1, 3, 6, and 12 months., Results: After 12 months of follow-up, the Conseal F sealant showed significantly better retention (p = 0.001), marginal adaptation (p = 0.023) and reduced marginal discoloration (p = 0.004) in comparison to the UltraSeal XT Hydro sealant., Conclusions: The Conseal F (hydrophobic) sealant demonstrated superior retention, marginal adaptation and marginal discoloration compared to the UltraSeal XT Hydro (hydrophilic) sealant.

Objectives: Dental caries is a common chronic disease amongst children and are typically evaluated using the DMFT/deft index (decayed, missing, and filled teeth for permanent dentition/decayed, extracted, and filled teeth for primary dentition). To address the limitations associated with these indices, alternative assessment tools such as the Caries Assessment Spectrum and Treatment (CAST) index and Ora test have been developed. These methods aim to estimate caries activity within the oral cavity more accurately. The objective of our study was to evaluate and correlate caries activity in 5-to-8-year-old children using Ora test and CAST index. Materials and Methods: Thirty schoolchildren between the ages of 5 and 8 years were selected and allocated into two groups (n=15) with DMFT/deft scores of <5 (group A) and >5 (group B). Two separate blinded examiners administered the assessments by first determining CAST scoring, which was followed by Ora test. Statistical analysis was performed using Pearson correlation test and significance was set at P≤0.05. Results: The mean time for color change of Ora test, was 118.53±23.28 minutes in group A and 53.33±15.07 minutes in group B. CAST severity scores were 3.67±2.08 and 15.7±9.70 for groups A and B, respectively. Time taken for color change in Ora test and CAST scores showed a significant negative linear relationship (P=0.039). Conclusion: Based on the negative correlation between CAST scores and Ora test, it may be postulated that microbial activity is directly related to caries activity in 5-to-8-year-old children., Competing Interests: None declared, (Copyright © 2023 The Authors.

Background: Local anesthesia (LA) is commonly used for pain control in clinical dental practice. However, it is often perceived as the most painful part of the treatment and the factor leading to the avoidance of dental care. Hence, research on better means of pain management is being conducted., Objectives: The aim of the study was to evaluate and compare pain perception using the No Pain III™ computer-controlled local anesthesia delivery (CCLAD) system and the conventional syringe, for inferior alveolar nerve block (IANB) in children., Material and Methods: Thirty children aged 6-12 years were included in the study. Children were randomly allocated into 2 groups by the flip of a coin. Group A received LA by conventional syringe and group B received LA by No Pain III™, on the contralateral side. Physiological parameters including blood pressure (BP), heart rate (HR) and respiratory rate (RR) were assessed at baseline, during the deposition and after the deposition of LA. A subjective evaluation of pain perception was assessed using the Wong-Baker FACES Pain Rating Scale (WBS). The measured values were subjected to statistical analysis., Results: A statistically significant difference was observed between group A and group B for pain perception using the WBS, systolic BP and RR., Conclusions: The use of the No Pain III™ CCLAD system resulted in reduced pain perception and better acceptance when compared to the use of the conventional syringe, for IANB in children.

Background: Successful outcome of endodontic treatment depends on chemomechanical preparation of the tooth. However, during canal preparation, debris may extrude through the apical foramen causing postoperative complications. The aim of this study is to evaluate and compare the amount of apically extruded debris during the pulpectomy procedure in primary molar teeth using two different rotary files and hand files., Materials and Methods: Distal roots of sixty extracted primary molars were divided into three groups: group A: Prime Pedo™ pediatric rotary files, group B: DXL-Pro Pedo™ pediatric rotary files, and group C: hand files. Myers and Montgomery experimental model was used. Preweighed Eppendorf tubes were used to collect apically extruded debris. The tubes were then placed in an incubator at 70°C for 5 days. The weight of the debris attained was determined. The data were analyzed using ANOVA and post hoc Bonferroni test., Results: Hand files produced more apical debris extrusion ( P < 0.05). Prime Pedo™ pediatric rotary files produced the least debris ( P < 0.05)., Conclusion: Prime Pedo™ and DXL-Pro Pedo™ pediatric rotary files extruded significantly lower amount of debris apically during pulpectomy as compared to hand files. Rotary files can be considered an alternative to hand files in pediatric endodontics., Competing Interests: The authors declare that there are no conflicts of interest regarding the publication of this paper., (Copyright © 2022 Komal Nanavati et al.)

Introduction: The root canal system in primary molars is considered to be complex. The aim of the present study was to assess the morphology of roots and root canals of primary maxillary and mandibular second molars using the cone-beam computed tomography (CBCT)., Materials and Methods: From a total of 104 collected primary maxillary and mandibular molars (51 maxillary second molars and 53 mandibular second molars), 60 teeth (30 each of maxillary and mandibular second molars) were selected randomly and accordingly assigned into two groups: MAX2M (primary maxillary second molars) and MAN2M (primary mandibular second molars). CBCT was used to assess the number of roots and root canals, length of root, mesiodistal and buccolingual width of the canal, shape of the canal, and intercanal communications. Descriptive statistical analysis was performed using the SPSS software version 17.0., Results: The mandibular second molars showed the presence of two roots in 27 sample molars while the presence of three roots was observed in three MAN2M group. In these molars, all three roots exhibited Type I root canal configuration. The maxillary second molars exhibited three roots. A total of nine intercanal communications were seen in MAX2M group, whereas two communications were seen in MAN2M group. The palatal root in MAX2M group was more angulated (mean value: 127.21 ± 9.10) as compared to mesial (mean value: 95.39 ± 8.64) and distal roots (114 ± 11.24)., Conclusion: The comprehensive knowledge of root and canal morphology of primary molars and anatomic variations is essential for successful endodontic therapy., Competing Interests: None

This in vitro study aimed to evaluate and compare the microleakage of bioactive, ormocer, and conventional glass ionomer cement (GIC) restorative materials in primary molars. In this study, class V cavities were prepared on the buccal surface of 75 noncarious extracted primary molars. The teeth were then restored as per the groups assigned. Group A, group B, and group C used bioactive restorative materials, ormocer restorative materials, and conventional GIC restorative materials for restorations, respectively. The teeth were then thermocycled and subjected to microleakage analysis via dye penetration. The microleakage scores were compared for differences using the Kruskal-Wallis test. This was followed by multiple pairwise comparisons using the Dunn test. All testing was carried out using a 'p' value of <0.05. The percentage of samples showing microleakage score 0 depicting no dye penetration was highest for group A (56%) followed by group C (44%) and group B (12%). Statistical analysis revealed highest microleakage with group B, which was statistically significant ( p  < 0.05). Microleakage was evident in all the materials tested. The lowest microleakage was seen with bioactive restorative material., Competing Interests: The authors declare that there are no conflicts of interest., (Copyright © 2022 Khushboo Jain et al.)

Background: A thorough knowledge of root and root canal morphology in primary dentition is essential for success of endodontic therapy. This information also finds importance in anthropological research in reconstructing human population history. Lack of studies of root and root canal morphology in mandibular anterior teeth prompted us to the present study., Methods: A total of 109 extracted primary mandibular incisors and canines were collected, out of which 90 teeth were selected for this study and divided into 3 groups: CI, mandibular central incisor; LI, mandibular lateral incisor; C, mandibular canine. All the sample teeth were scanned using cone beam computed tomography (CBCT). Number of roots, number of root canals, length of root, mesiodistal (MD), and buccolingual (BL) width of canal, shape of canal, and presence of accessory canals were assessed. Collected data were statistically compared using one-way ANOVA and chi-square tests., Results: All teeth studied displayed single root with single root canal conforming to type I Vertucci's classification. Root length of CI was significantly shorter than both LI and C, with no significant difference between LI and C. Straight root canals were more common in CI and LI, whereas curved canals were more common in C. S-shaped canals were seen in a few CI and C. BL canal width was more than MD width in all teeth, C showing significantly larger dimensions than both CI and LI., Conclusion: This study presents root and root canal characteristics of primary mandibular central incisor, lateral incisor, and canine in children from Indian ethnicity., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2022 Farhin Katge and Uma B.

In forensic sphere and clinical dentistry, age estimation is a topic of utmost importance. Various techniques are employed in children to determine age; however, dental development has proven to be an appropriate method because of its low variability. Cameriere's method is a widely accepted method of age estimation in children, which is carried out by measuring the projections of open apices and also the heights of developing permanent teeth seen on panoramic radiographs. The aim of this study is to establish a new formula for age estimation in the Western Indian population by measuring the open apices of mandibular teeth using Cameriere's European formula. For this study, we included 311 panoramic radiographs of healthy children living in Western India (Maharashtra, Gujarat, and Goa) aged 4-15 years which were analysed by two independent researchers. Seven left permanent mandibular teeth were assessed for length and width of open apices. Dental maturity was evaluated using measurements of the left seven permanent mandibular teeth ( x i  =  A i / L i , i  = 1,…, 7), the sum of the normalized open apices ( s ), and the number ( N 0) of teeth with complete root formation. A linear relationship between open apices, N 0, age, and other factors was evaluated with the aid of a stepwise multiple regression model. A stepwise linear regression showed that all parameters, gender, s , N 0, and x 5 , were significantly associated with age ( R  = 85%). No statistically significant difference was found between the predicted and actual chronological age of children in the age group of 4-13 years using the regression equation for the Western Indian population. The present research suggests that the new regression formula developed will be more accurate for age assessment in the Western Indian population., Competing Interests: The authors declare that there are no conflicts of interest regarding the publication of this paper., (Copyright © 2022 Sanjana Manjrekar et al.)

Statement of the Problem: The success of dental restorations depends mainly on its ability to bond to dental structures and resist the multitude of forces acting on it within the oral cavity., Purpose: Therefore, the aim of this study was to evaluate the shear bond strength (SBS) of three different glass ionomer based restorative materials., Materials and Method: In this in vitro analytical study, 30 intact primary molars were sectioned buccolingually to obtain 60 sections. These sections were embedded in auto polymerizing acrylic resin and polished to obtain a flat dentin surface. Restoration cylinders were built on the dentin surface with the help of a Teflon template called bonding jig. Each group (n= 20) was restored as group A with conventional glass ionomer cement (GIC) (GC Fuji Gold Label Type 9), group B with Bioactive restorative material (ACTIVA TM KIDS BioACTIVE Restorative material), and group C with Zirconia reinforced glass ionomer cement (Zirconomer). Following restoration, SBS testing was performed using Universal Testing Machine. The data obtained were statistically analyzed using One way ANOVA test and post hoc Tukey test ( p = 0.05)., Results: The SBS values were significantly greater in the ACTIVA KIDS group as compared to the other two groups ( p < 0.05). There was no significant difference in the SBS values between group B and group C ( p > 0.05)., Conclusion: The SBS of the ACTIVA KIDS to primary teeth dentin was the highest as compared to Zirconomer and conventional GIC. Therefore ACTIVA KIDS may protect primary teeth against recurrent caries and failure of the restoration., (Copyright: © Journal of Dentistry.)

Context: Control of pain during dental treatment is an essential aspect of pediatric dentistry., Aims: This study was conducted to evaluate and compare the anesthetic efficacy of 4% articaine buccal infiltration with 2% lignocaine inferior alveolar nerve block (IANB) for primary mandibular molar extractions., Settings and Design: The study was a prospective, split-mouth, randomized controlled trial., Methods: Bilateral symmetrical carious primary mandibular molar (n = 92) extractions in 46 healthy children aged 5-10 years were included in this randomized controlled trial. Extraction was performed on one side using 4% of articaine buccal infiltration and on the contralateral side using 2% lignocaine IANB in two subsequent appointments. Pain and behavior were assessed at baseline, during injection and extraction using Wong-Baker Faces Pain Rating Scale, Modified Behavior Pain Scale (MBPS), and Frankl Behavior Rating Scale., Statistical Analysis Used: Values thus obtained were statistically analyzed by one-way analysis of variance test and compared using independent samples test., Results: According to MBPS, the mean value of pain experienced in the form of cry during injection was reported to be more for 2% lignocaine IANB (1.76) as compared to 4% articaine buccal infiltration (1.30), which was statistically significant (P = 0.024). Comparison of behavior depicted showed no statistically significant difference between the groups., Conclusion: Buccal infiltration with 4% articaine can be utilized as an effective alternative to 2% lignocaine IANB for primary mandibular molar extractions., Competing Interests: None

The recent spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its associated coronavirus disease (COVID-19) has caused widespread public health concerns. Despite huge efforts to contain the disease spread, it is still on the rise because of the community spread pattern of this infection. In order to prevent the community spread, a nationwide lockdown was implemented, due to which many restrictions were imposed on movements of citizens within the country. Since the dental professionals were at the forefront of acquiring the infection, the majority of the dental clinics were shut for routine dental procedures. Only emergency treatment was provided to the patients. However, due to restrictions in movement, it was difficult for the patients to visit the clinics for routine check-ups. This was overcome by the advancements in technology which has a major impact on medicine. Due to increased usage of smartphones and related software applications, the clinical data exchange was facilitated between patients and clinicians which has been termed as "teledentistry." Teledentistry is a combination of telecommunications and dentistry, involving the exchange of clinical information and images for dental consultation and treatment planning. This technology served as a boon for the dentists to manage dental emergencies during the lockdown period. This narrative review discusses teledentistry and its applications in general and specialty dental practice amidst the COVID-19 lockdown., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2021 Shantanu Deshpande et al.)

The outbreak of coronavirus disease 2019 (COVID-19) rapidly escalated into a worldwide pandemic, creating a global health and economic crisis. It is a novel virus which is distinct from SARS-CoV and MERS-CoV, with Chinese horseshoe bats being the most probable origin. Transmission occurs primarily through droplet spread or contact routes. Due to the characteristics of dental settings, the risk of cross infection between dental health care personnel (DHCP) and patients can be very high. This article provides a brief overview of the structure of the virus, modes of transmission, and clinical features of COVID-19 disease. The aim of this article is to recommend infection control strategies and patient management protocols to provide optimum dental care and simultaneously prevent nosocomial infection in dental settings., Competing Interests: The authors declare that there are no conflicts of interest regarding the publication of this paper., (Copyright © 2020 Parin Bhanushali et al.)

The aim of this study is to compare the accuracy of Demirjian and Dental Age Research London Information Group (DARLInG) methods of dental age estimation in western Indian children. A total of 485 dental panoramic radiographs of children aged between 4 and 15 years were included in this study. Dental age was estimated based on the degree of mineralization of permanent teeth in the left side of the arch. Dental age was estimated from the scores obtained from the Demirjian and DARLInG's United Kingdom Caucasian datasets respectively. The difference between the chronological age (CA) and dental age (DA) in each range (CA-DA) was analysed using paired t-test. The age and sex-based differences of the estimated age using the two methods were tested using ANOVA and Pearson correlation co-efficient analysis. The overall mean CA was 8.74 years and 9.00 years for boys and girls respectively. The overall mean difference (CA-DA) using the Demirjian's method for boys and girls were -0.68 years and -0.52 years respectively (p < 0.05). Using the DARLInG's method, the overall mean difference (CA-DA) was -0.31 years and -0.34 years for boys and girls respectively (p < 0.05). Between the two methods, significant differences were observed in different age groups (p < 0.05). Pearson correlation coefficient showed significant positive correlation between dental age estimated from the Demirjian and DARLInG methods (p < 0.05). The DARLInG method provided better estimate of age compared to Demirjian method in the western Indian population. However, an ethnic specific reference dataset specific to this population would likely produce accurate age estimates., (Copyright © 2019 Elsevier B.V. All rights reserved.)

Introduction: Distraction is commonly used nonpharmacologic pain management technique by pedodontists to manage pain and anxiety. There are some new techniques which uses audiovideo stimulation and distract the patient by exposing him or her to three-dimensional videos. These techniques are referred to as virtual reality audiovisual systems. The aim is to evaluate the effectiveness of virtual reality eyeglasses as a distraction aid to reduce anxiety of children undergoing extraction procedure., Objective: The aim of this study is to evaluate the effectiveness of virtual reality eyeglasses as a distraction aid to reduce anxiety of children undergoing dental extraction procedure., Materials and Methods: Thirty children of age 6-10 years ( n = 60) with bilateral carious primary molars indicated for extraction were randomly selected and divided into two groups of 30 each. The first one was group I (VR group) ( n = 30) and group II (control group) ( n = 30). Anxiety was measured by using Venham's picture test, pulse rate and oxygen saturation. Anxiety level between group I and group II was assessed using paired " t " test., Results: The mean pulse rate values after extraction procedure in group I were 107.833 ± 1.356 and group II were 108.4 ± 0.927 respectively. The pulse rate values in intergroup comparison were found statistically significant p = 0.03., Conclusion: The virtual reality used as a distraction technique improves the physiologic parameters of children aged 6-10 years but does not reduce the patient's self-reported anxiety according to Venham's picture test used., How to Cite This Article: Koticha P, Katge F, et al.

In Group IV, mesial root exhibited 100% Type IV and distal root had 43.33% Type I and 65.67% Type IV canal anatomy., Conclusion: Vertucci's Type I root canal configurations were most frequently observed., Competing Interests: There are no conflicts of interest

Background: Dental stem cells derived from tooth structures are adult stem cells that have received attention of researchers over the past decade. Dental stem cells can be used to regenerate dental tissues as well as non dental organs. These dental stem cells are readily accessible as compared to other sources of stem cells and can be obtained and stored for future use through minimally invasive procedures. Research in this field is growing at a fast pace and it is essential that awareness regarding the same should be present amongst professionals., Aim: This study was carried out to assess the knowledge and attitude of Indian dentists regarding dental stem cells., Material and Methods: A cross sectional descriptive, questionnaire based survey based on Knowledge, Attitude and Practice (KAP) was conducted and a total of 823 dentists from Maharashtra, India participated in the survey. The Pearson's Chi-Square Test and percentages of the total were used for statistical analysis., Results and Conclusion: A total of 823 dentists completed the questionnaire survey; out of which 396 were male and 427 were female. Maximum respondents (53%) were dental graduates, followed by post graduates (45%) and PhD (1.7%). Data from the study revealed that there is good awareness regarding stem cells in general. However; the awareness, knowledge regarding sources, applications, uses and clinical research guidelines regarding dental stem cells is lacking amongst most dentists. Despite this lack of knowledge, dentists are keen on updating their knowledge regarding dental stem cells.

Objectives: The aim of this study was to compare the cleaning efficacy and instrumentation time between manual Hedstrom files (H-files) and rotary Mtwo files in primary molar root canals., Materials and Methods: A total of 90 primary root canals were selected using standardized radiographs. The canals were injected with India ink with 30 gauge insulin syringe and divided into three groups. Group I-30 root canals instrumented with H-files, group II-30 root canals instrumented with Mtwo files, and group III-control group in which no canal instrumentation was done. The teeth were cleared in various solutions and then observed under a stereomicroscope., Results: No significant difference was seen in cleaning efficacy between H-files and Mtwo files in coronal, middle, and apical thirds of the root canal. The instrumentation time recorded for H-files (3.41 ± 0.38 minutes) was significantly less than that of Mtwo files (4.81 ± 0.52)., Conclusion: Although there was no significant difference in cleaning capacity, further studies should be carried out using the single file systems.

Aim: To compare the accuracy and repeatability of three diagnostic systems; visual inspection, bitewing radiography, and CarieScan PRO for occlusal caries diagnosis in primary molars., Materials and Methods: 216 occlusal surfaces of primary molars examined in turn by two examiners using each of three diagnostic systems (visual inspection, bitewing radiography, and CarieScan PRO). Examiners indicated operative intervention (validation method) for 104 teeth which were used for statistical analysis. The validation method was cavity preparation when the two examiners agreed about the presence of dentinal caries. Sensitivity, specificity, likelihood ratio, positive predictive value (PPV), and negative predictive value (NPV) were calculated for each diagnostic technique. Inter- and intra-examiner repeatability was calculated for each diagnostic system using the Cohen's kappa statistics., Results: Visual inspection showed the highest sensitivity (0.93). The highest sensitivity and NPVs were provided by CarieScan PRO (0.97 and 0.95, respectively) however this was offset by a lower specificity (0.82) compared to other techniques. The CarieScan PRO gave the highest values of Cohen's kappa statistics., Conclusion: This study showed low sensitivity but substantial specificity with visual inspection. Bitewing radiography performed poorly overall when compared with the other two systems. The CarieScan PRO technique gave the highest overall combination of sensitivity and specificity for detection of occlusal caries.

Aim: To evaluate microleakage of Nanoionomer (3M ESPE Ketac(™) N100 Light cured Nanoionomer Restorative) and Nanocomposite (3M ESPE Filtek(™) Z350 XT Universal Restorative) restorations, immersed in fruit drink, fresh fruit juice and soft drink., Study Design: Eighty caries free maxillary premolars extracted for orthodontic purpose were used for the study. Class V cavities were prepared and restored with Nanocomposite on buccal surface and Nanoionomer on the palatal surface. The teeth were thermocycled following the restoration. The experimental groups comprised of 72 teeth (3 groups comprising 24 teeth each for fruit drink, fresh fruit juice and soft drink), while remaining 8 formed the control group. Each of experimental group was further divided into three subgroups (low, medium and high immersion). The teeth were finally immersed in Rhodamine B dye, sectioned and evaluated under stereomicroscope. Statistical analyses used were Mann-Whitney test and ANOVA test., Results: The teeth showed statistically significant microleakage as the immersion regime increased. Soft drink group showed highest microleakage followed by fresh fruit juice and fruit drink. Nanocomposite exhibited more microleakage but the comparison was not statistically significant., Conclusion: The three beverages used in the study affected the microleakage of both restorative materials significantly. The microleakage scores increased as the frequency of the immersions increased. Soft drink caused highest microleakage followed by fresh fruit juice and fruit drink.

Aim: To assess the DMFT index of children with Special Health Care Needs (SHCN) in Navi Mumbai. To correlate the DMFT index with Streptococcus mutans count in the supragingival bacterial biofilm and with plaque pH., Materials and Methods: Dental examination of 158 patients aged 5-18 years was conducted to determine the DMFT/dmft index. Supragingival plaque samples were collected from the buccal surfaces of all teeth. The samples were inoculated in mitis salivarius bacitracin agar medium and incubated at 37°C for 48 h. Supragingival plaque was collected from interproximal sites of the molar area (preferably mandibular) for conducting plaque pH test. Chi-square test and Pearson's correlation were used to find the significance of the study parameters on categorical scale between the two groups., Results: The mean DMFT recorded was 4.90 ± 4.63 and the mean dmft recorded was 1.77 ± 3.14. Mean number of S. mutans colony-forming units found was 2.961 × 10(4). Mean plaque pH recorded was 6.2., Conclusion: No statistically significant correlation was found between the DMFT index with the number of S. mutans and plaque pH.

Objective: Early childhood caries is now affecting the children in dangerous proportions. There is a wide spread loss of the tooth material irrespective of the type of the carious lesion. Restoration of such lesions with a strong permanent bond between the dental tissues and the restorative dental materials would be a highly desirable requisite. Ultramorphological characterizations show that the interfacial morphology and the chemical characterization of the bonding systems appear to be strongly associated with each other and, therefore, observing and understanding the interfacial phenomenon and its quality would be of great importance in the selection of a dental adhesive for its use in pediatric restorative dentistry., Study Design: Human primary molars, which were indicated for extraction, for an array of reasons like caries, normal exfoliation, pathological root resorption, over-retained and serial extraction, were collected for the study purpose. Total number of teeth was then equally distributed into two subgroups, each namely A1 (Prime and Bond NT) and A2 (Xeno III)., Results: The type of etching pattern that was observed in group A1 (Prime and Bond NT) of Silverstone's type II compared to the Silverstone's type III observed in group A2 (Xeno III)., Conclusion: RESULTS of this study indicate that the use of an etchant separately followed by the application of the bonding system-Prime and Bond NT-would provide a better quality of adhesion thus improving the quality and longevity of the restoration done within the limits of enamel in primary dentition.

Background: Paediatric Endodontics is an important clinical procedure commonly used to manage pulpally involved or non-vital teeth in children. One of the important steps in root canal preparation in deciduous teeth is the removal of organic debris., Aim: The aim of this study was to compare instrumentation time and cleaning efficacy of manual instrumentation, rotary systems and reciprocating systems in the preparation of primary molar root canals., Materials and Methods: India ink was injected into 120 root canals of maxillary and mandibular primary molars. The teeth were randomly divided into three experimental groups, Group one K-file (n = 30), group two ProTaper (n = 30), group three WaveOne (n = 30) and one control group (n = 30). The root canals were prepared using one of the three file system followed by clearing the teeth with different demineralizing solutions. The results were statistically evaluated using Kruskal-Wallis tests., Results: The file systems were compared at coronal, middle and apical level. In the coronal third, WaveOne showed more ink removal and the difference found was highly significant (P < 0.0001). In the middle third of the root canal, WaveOne performed better than ProTaper and K-file (P < 0.005). At the apical level, there was no statistical difference between the three systems., Conclusion: The reciprocating and the rotary systems showed better cleaning efficacy when compared to manual instrumentation especially, in coronal and middle one third.

Dentists often find foreign bodies in the primary dentition of children who habitually place objects in their mouths. The objects are frequently embedded in exposures that result from carious or traumatic lesions or from endodontic procedures that have been left open for drainage. Such bodies are often detected on routine radiographs and, less frequently, during clinical examination. We report a case of a 6-year-old boy who had inadvertently embedded a screw in his mandibular right first primary molar and had forgotten about it until it became symptomatic. The screw was impacted in the exposed pulp chamber due to a large carious lesion in the affected molar. This case report considers the possible medical and dental consequences of placing foreign bodies in the mouth.
