Lesion sterilization and tissue repair (LSTR) treatment involves the use of a triple antibiotic mixture in a suitable vehicle, which is used to disinfect root canal systems. This report highlights three cases where LSTR therapy using triple antibiotic paste was attempted in primary molars exhibiting gross periradicular pathosis and internal resorption. Follow-up examinations revealed reduction of periradicular pathosis and reversal of internal resorption in all the three cases. This case series opens a perspective on the use of LSTR therapy as an alternative option to extraction in treating primary teeth with gross periradicular pathosis and internal resorption.

Introduction: Though a large number of agents including chlorhexidine have been used for cavity disinfection during restorative procedures, till date none has proved to be "ideal." Thus, there is a need for an alternative cavity disinfectant, which is safe, effective, and economic. Herbal extracts of Aloe vera and propolis have shown the potential to be used as cavity disinfectants but not much is known about them. The aim of this study was to evaluate and compare the antibacterial activity of ethanolic extracts of Aloe vera and propolis against S. mutans and L. acidophilus, along with assessing the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). Materials and Methods: The study included three groups: 2% chlorhexidine solution (group I), ethanolic extract of Aloe vera (group II), and ethanolic extract of propolis (group III). An MIC test was carried out using tissue culture microplates and serial dilution technique and later to MBC, an aliquot of each incubated well with concentrations higher than MIC was subcultured on brain heart infusion (BHI) medium. Antibacterial assay was carried out using agar disk diffusion technique and zones of inhibition were determined. One-way analysis of variance (ANOVA) was used for intergroup comparison followed by post hoc Tukey's test for groupwise comparison. Results: Group II and Group III showed bacteriostatic effect but no bactericidal effect against both S. mutans and L. acidophilus. There was a significant difference in the antibacterial activity against both the tested microorganisms among all the groups, the highest being in group I followed by group II and group III. Conclusions: Ethanolic extracts of Aloe vera and propolis are only bacteriostatic and their antibacterial efficacy is inferior to chlorhexidine against both S. mutans and L. acidophilus.

Dental fear and anxiety (DFA) serves as significant problem in child patient management as it leads to greater prevalence and increased severity of the disease associated with delayed dental visits. Therefore, it is necessary to effectively predict children dental behaviour and identify children at risk of Behaviour Management problems. Study of factors influencing DFA and its association with behaviour in children during first dental visit. The study included 209 children (5-14 years). DFA levels were assessed using 3 standardised questionnaires i.e. Facial Image Scale (FIS), Dental Anxiety Scale (DAS), Children’s Fear Survey Schedule – Dental Subscale (CFSS-DS). The behaviour of the child was then assessed using Frankl’s Behaviour Rating Scale (FBRS). The data were analysed, and a correlation was established between DFA and behaviour using statistical analysis. Presence of DFA according to FIS is 13.4%, according to DAS is 15.2% and according to CFSS-DS is 17.7%. Maximum participants showed positive behaviour (81.8%) according to FBRS. Factors causing maximum Dental anxiety according to DAS was anticipation of treatment (26.30%) and factor which caused maximum dental fear according to CFSS-DS was injections (45.4%). There is association between DFA and behaviour in children during first dental visit. This study will help assess the factors which lead to dental fear and anxiety in children and also find a correlation between dental fear and anxiety and behaviour management problems which can help the Paedodontist to predict various behaviour management problems and to avoid the factors which lead to them before the initiation of the dental treatment. This can lead to a decrease in the fear and anxiety levels of children which will further lead to better treatment and in turn better case management.

Aim: The aim of the study was to evaluate if vinegar and vinegar with 3.5% sodium chloride could be used as an alternative to chlorhexidine gluconate for disinfection of toothbrushes.Materials and methods: The study consisted of three groups: group I: 0.12% chlorhexidine digluconate, group II: 38% white vinegar, and group III: 38% white vinegar with 3.5% sodium chloride. Two new toothbrushes were cultured to check their sterility before use. Eight children in the age group of 6 to 12 years were given oral hygiene instructions and four sets of oral hygiene kits. At the end of the 1st week, one set of used toothbrushes was cultured to check for total viable count. Again at the end of the 2nd, 3rd, and 4th weeks, the 2nd, 3rd, and 4th sets of brushes were collected, subjected to respective decontamination treatment for 12 hours, and then cultured for microbial analyses. The obtained data were analyzed using Fisher's exact test.Results: In group I, three out of eight brushes showed 1 to 10,000 colonies, in group II, one out of eight cases showed >10,000 colonies and two out of eight showed 1 to 10,000 colonies, and in group III, all the eight cases showed no colonies upon culturing.Conclusion: Out of all the tested decontaminating agents, combination of 38% white vinegar and 3.5% sodium chloride was found to be the most efficient.Clinical significance: Toothbrushes become contaminated upon use and act as a reservoir for microorganisms. Thus, toothbrush decontamination should become a routine practice. Testing the disinfecting efficacy of vinegar and common salt is, thus, beneficial as they are available in every kitchen.How to cite this article: Mavani V, Mahabala KY, Suman E, Natarajan S, Nayak PA, Srikrishna SB, Rao A.

Background: The application of Silver diamine fluoride is an effective approach in controlling dental caries. But the black discoloration caused by its application is unaesthetic and is of greater concern to the parents. Aim: To assess the potential color masking ability of tooth colored restorative material over discoloration caused by 38% SDF using a UV‒VIS-NIR spectrophotometer. Material and methods: 20 extracted teeth were taken and randomly divided into 4 groups: Group A: 38% SDF + GIC; Group B: 38% SDF + RMGIC; Group C: 38% SDF+ Composite; Group D: 38% SDF+ Cention N. Two readings were recorded, one on application of 38% SDF and second after application of test materials using a UV‒VIS-NIR spectrophotometer. Result: The intragroup comparison for color masking ability (ΔE) for all four restorative materials revealed no statistically significant differences, with a test value of 1.168 and a p value of 0.353, and the highest mean was observed in Group A, i.e., 38% SDF + GIC (9.171966) Significant differences in color were observed, with more shifts toward yellow in group A (2.488 ± 2.957) and group D (1.686 ± 0.559) and more shifts toward green in groups B (−0.088 ± 0.34) and C (−0.062 ± 0.5). The mean lightness was greatest for Group C, i.e., the composite group (86.396 ± 3.741), and least for Group A, i.e., the GIC group (76.664 ± 8.213). Conclusion: All 4 restorative materials were equally effective in terms of color masking over 38% SDF discoloration.
