Context: The goals of orthodontic therapy are to provide stable treatment results and the best possible tooth alignment. Orthodontic retention regimens are essential for avoiding relapses after treatment; however, there is ongoing discussion on the best regimen. Methods: Orthodontic patients treated at a tertiary care center were the subject of a retrospective analysis. Information was gathered about follow‑up evaluations, treatment techniques, patient demographics, and retention procedures. Relapse rates and occlusal characteristics were among the objective variables used to evaluate treatment stability. A statistical analysis evaluated the effectiveness of various retention strategies. Findings: When it came to preserving treatment stability, fixed retainers outperformed detachable appliances, Hawley retainers, and Essix retainers. The mean changes in occlusal parameters and relapse rates were greater for removable appliances, but the performance of Hawley and Essix retainers was moderate. Significant variations in retention techniques were verified by statistical analysis, with fixed retainers outperforming alternative detachable retainers and removable appliances. In conclusion, compared to alternative detachable retainers and removable equipment, fixed retainers are more successful in preserving treatment stability. Retention protocols, however, must to be established with each patient’s needs and treatment preferences in mind. The length of patient compliance and retention has a crucial role in determining the stability of therapy, underscoring the significance of patient education and continued monitoring. To improve long‑term treatment results and optimize orthodontic retention techniques, further research and technical developments are required. [ABSTRACT FROM AUTHOR]

Objective: This systematic review examines the efficacy and biocompatibility of orthodontic clear aligner tooth aligners constructed from polyethylene terephthalate glycol (PeT-G), polypropylene (PP), polycarbonate (PC), thermoplastic polyurethanes (TPUs), and ethylene-vinyl acetate (EVA). Materials and Methods: To find relevant papers published through September 2021, PubMed was searched extensively. Randomized clinical trials (RCTs) and observational studies assessing the effectiveness and biocompatibility of the aligner materials were included. Data were extracted independently, and the quality of included research was appraised using relevant procedures. The research variability necessitated a narrative synthesis. Results: Five studies were included for comparison. All materials were biocompatible; however, PeT-G and EVA aligners caused the least tissue irritation. Patients preferred TPU aligners for initial comfort and PeT-G aligners for transparency and endurance. Conclusion: Biocompatible PeT-G, PP, PC, TPU, and EVA tooth aligners fix malocclusions. Aligner materials should be chosen based on patient preferences, treatment goals, and material qualities. For stronger proof, a longer-term study is needed. [ABSTRACT FROM AUTHOR]

Background: Low vaccination rates, especially in rural regions, and vaccine hesitancy are serious problems for public health. The goal of this study is to determine whether the BeSD (Behavioral Support for Vaccination) tool has a positive impact on parents who live in rural areas near Visakhapatnam who choose to vaccinate their children. The BeSD tool is made to help people make educated decisions about immunizing their children and to alleviate vaccination hesitancy. Methods: To assess the effect of the BeSD tool on immunization uptake, a quantitative research technique was used. Using a standardized questionnaire, a sample of 374 parents from rural areas near Visakhapatnam were questioned. The survey had parts on vaccination uptake, risk factors for vaccine hesitancy, and the use and efficacy of the BeSD tool. A statistical analysis of the data was done using the right techniques. Results: According to this study's findings, 64.17% of the parents who participated in the survey said their children had received all recommended vaccinations, 23.00% said their children had received some vaccinations, and 12.83% said they had not. Lack of knowledge (32.09%), safety worries (20.86%), and a lack of faith in vaccines (17.38%) were all factors in vaccine hesitation. The BeSD tool's use led to a 64.17% vaccine uptake among the intervention group. Conclusion: The findings of this study show that the BeSD tool has the potential to increase vaccination rates among parents who live in rural areas close to Visakhapatnam. The BeSD tool can assist increase immunization rates and contribute to better public health outcomes by addressing vaccine reluctance through focused interventions, such as offering information and support. The results highlight the significance of specialized approaches to overcoming vaccine reluctance in rural communities. [ABSTRACT FROM AUTHOR]

Background: Nanosized antibacterial agents can be used to prevent biofilm buildup on orthodontic appliances and auxiliaries, limiting microbial adherence and preventing caries. Nanoparticles (NPs) can enhance the antibacterial properties of orthodontic materials due to their smaller particle size and larger surface area. Materials and Methods: The study's material analysis was divided into four groups, numbered I through IV, using Transbond XT Primer as a control and modifying group I by adding various antibacterial agents. 98.1 g of mutans–sanguis agar was dissolved in 1,000 ml of warm distilled water and autoclaved for 15 minutes at 121°C and 15 lb pressure. 176 disk specimens of 6 mm in diameter were created, sterilized in an autoclave, and heated to 60°C in a hot air oven for 1 hour. Ten milliliters of primer containing different antimicrobial agents was applied to the sterilized disks. Four petri plates were used for each concentration, with 16 disks in each group. 44 petri plates in all were utilized. Results: The orthodontic primer modified by the addition of antibacterial agents showed a significantly increased antimicrobial activity, and nanobenzalkonium chloride (BAC) at 5% concentration showed the highest antimicrobial efficacy among all groups. Nanohydroxyapatite showed the least. Conclusion: Within the confines of the current investigation, it was determined that the addition of antibacterial agents had significantly higher antimicrobial activity and BAC at 5% concentration had the highest antimicrobial efficacy of all the groups.

Introduction: Orthodontic treatment may bring about changes in the temporomandibular joint (TMJ) disc. Hence, we aim to assess the impact of the orthodontic tooth movement on the articular disc repositioning of TMJ. Materials and Methods: We conducted an observational prospective study among 50 class IIdiv-I subjects. The magnetic resonance images were used to evaluate TMJ during the orthodontic treatments. The phases were T1-start of treatment, T2-thru phase I, T3-at the end of phase I, and T4-at the end of phase II. The qualitative values were compared for the disc changes. Results: No significant changes in the disc position or the regression were seen with open or closed mouth between T1-T3, T3-T4, and T1-T4. Significant variation for the position of the disc was seen in the opened mouth between T3-T4. Significant variation for the form of the disc was seen when closed at T1-T2 and T2-T3. Conclusions: Disc of the TMJ maintained the form and position during the treatments. [ABSTRACT FROM AUTHOR]

Introduction: One of the hormones that are crucial in safe pregnancy is the Progesterone. Its defect may cause bleeding and abortion. Hence, in this study, we evaluated two different drug modalities of progesterone for their efficacy. Material and Methods: We piloted a prospective observational study among 100 pregnant women in their first trimester. They were divided to two equal groups to receive oral dydrogesterone and vaginal progesterone. The clinical and the demographic data with detailed history were taken and noted. The patients were followed up till the pervaginal bleeding stopped and till second trimester end. The comparisons were made between the groups using Chi square test deliberating P < 0.05 as significant. Results: The age, BMI, and the progesterone levels were comparable between the groups. No significant difference between the groups was seen for the adverse reactions and for the continuation of pregnancy till 24 weeks. However, there was a significant variation in the cessation of the pervaginal bleeding, with lower time for the oral dydrogesterone. Conclusion: Compared to the vaginal progesterone, oral dydrogesterone performed better in preventing the pervaginal bleeding and prolonging the viability of the pregnancy till the second trimester end.
