Background:One of the unfavorable outcomes of endodontic treatment in primary molars is furcal perforation. During treatment, bacterial infection at the site of perforation should be prevented for better prognosis.Aim:This study aims to compare sealing ability of mineral trioxide aggregate (MTA) Plus™ and Biodentine™ for the repair of furcal perforation in primary molars using spectrophotometry.Materials and Methods:Access opening was done for all ninety extracted teeth. Perforation was made in furcation area in all the teeth. The sample size consisted of ninety extracted teeth. They were divided into four groups, Group 1 (n = 30) in which perforations were repaired with MTA Plus™, Group 2 (n = 30) in which perforations were repaired with Biodentine™. The other two groups were considered as control groups, Group 3 (n = 15) in which perforations were left unsealed (positive control) and Group 4 (n = 15) without perforations (negative control). Dye extraction method was used to compare the sealing ability of MTA Plus™ and Biodentine™. Statistical analysis was done using ANOVA test to compare the mean between the different groups. Intergroup comparison was performed using post hoc Scheffe test.Results:The highest dye absorbance was seen in the positive control group with a mean value of 0.080 ± 0.033. The mean value of MTA Plus™ was 0.031 ± 0.026 and Biodentine™ was 0.024 ± 0.031.Conclusion:The mean value of dye absorption of MTA Plus™ was greater than Biodentine™ but it was statistically insignificant.

Aim:To evaluate the acceptance of silver diamine fluoride (SDF) among parents of pre-cooperative children. Materials and methods: This was a questionnaire-based study. Prevalidated questionnaires were distributed to the parents of pre-cooperative children with dental caries. The response rate was 100%. Data were statistically analyzed using Chi-square test. Results: Of 105 parents, 71.42% were mothers, 21.90% were fathers, and 6.66% were other caregivers. In relation to noncooperation of the children in the past, 22.85% of the parents of the children above 36 months chose SDF, whereas only 4.76% of the parents of children 36 months of age and below chose SDF (p = 0.047). Discoloration of front teeth was acceptable to 33.33% of the parents below the income of 25,000 INR and was not acceptable to 14.29% (p = 0.033). For front teeth, 33.33% of the parents above the income of 25,000 INR did not accept SDF treatment when there were behavioral barriers, whereas 13.33% accepted it (p = 0.003). Also, acceptance of SDF for back teeth was 32.38% to the parents below the income of 25,000 INR in contrast to 15.24% of who did not accept it (p = 0.001). Conclusion: SDF is acceptable to parents and potentially useful in patients who are unable to obtain traditional restorative treatments due to cooperation, access, costs, and apprehension of general anesthesia.
