RESUMO
Aim: The purpose of the study is to compare and evaluate the efficacy of different root canal irrigants-100, 75, 50, and 25% neem extract, 100, 75, 50, and 25% apple cider vinegar (ACV), a combination of 5.25% sodium hypochlorite (NaOCl) and 17% ethylenediaminetetraacetic acid (EDTA), and saline on smear layer removal using a scanning electron microscope (SEM). Materials and methods: A total of 80 freshly extracted single-rooted teeth were collected and divided into 10 groups-group I: normal saline (negative control), group II: NaOCl with EDTA (positive control), group III: 100% neem extract, group IV: 75% neem extract, group V: 50% neem extract, group VI: 25% neem extract, group VII: 100% ACV, group VIII: 75% ACV, group IX: 50% ACV, and group X: 25% ACV. The samples were irrigated with a specific group of irrigants, then split in a longitudinal axis and processed for analysis in an SEM. Microphotographs were obtained and scored according to Torabinejad et al. Results: Microphotographs were assessed and showed that 100% neem extract was similar to NaOCl with EDTA, followed by 75% neem extract and 100% ACV. Conclusion: This study showed that 100% neem extract removed the smear layer, similar to the NaOCl with EDTA. How to cite this article: Sudhakar S, Gupta N, Ghambir N, et al.

RESUMO
Aim: This study aims to evaluate and compare the effect of different varnishes: 3M ESPE Clinpro and Voco Profluorid and fissure sealants- 3M ESPE ClinPro and Ivoclar Vivadent Helioseal-F on the S. mutans count in the saliva of children. Materials and methods: Eighty children of 6-12 years of age with no incidence of caries were selected and saliva samples were collected by drooling method after oral prophylaxis. The children were divided randomly into four groups and materials were applied accordingly. Saliva samples were obtained immediately after the procedure as well as 1-month, 3-months and 6-months posttreatment. Saliva samples were inoculated on Mitis salivarius agar and colony counts of S. mutans were obtained. Results: This study showed that both the varnishes and pit and fissure sealants were equally effective in reducing the salivary S. mutans count in children in a time period of 6-months however pit and fissure sealants were more effective in preventing caries. Conclusion: Both varnishes and pit and fissure sealants are equally effective in reducing S. mutans count in saliva. How to cite this article: Sharma R, Ghambir N, Gupta N, et al.

RESUMO
OBJECTIVES: The purpose of this study is to compare the mechanical properties (compressive strength (CS) and diametral tensile strength (DTS)) of four different restorative materials: conventional glass ionomer (Fuji IX), ClearFil AP-X, Filtex Z350-XT, and Cention N. MATERIALS AND METHODS: Specimens (n = 80) were prepared from Fuji IX, ClearFil AP-X, Filtex Z350-XT, and Cention N for testing compressive strength and DTS. STATISTICAL ANALYSIS: Results obtained were subjected to one-way ANOVA and Tukey's post hoc test at significance (p < 0.001). RESULTS: There were significant differences among restorative materials tested. ClearFil AP-X exhibits the highest mechanical properties (CS and DTS) and least values were obtained by the Fuji IX. CONCLUSION: Strength is one of the most important criteria for the selection of a restorative material. Stronger materials better resist deformation and fracture, presenting more equitable stress distribution, greater probability, and greater stability of clinical success.
