A bstract Aim To determine the prevalence of traumatic dental injuries (TDI) in permanent anterior teeth and their association with risk factors among children aged 7–13 years of government and private schools in Kakinada and Rajanagaram of East Godavari district, Andhra Pradesh, India. Materials and methods A cross-sectional study was carried out among 2,325 school children aged 7–13 years. Each child was examined for TDI, degree of overjet, molar relation, lip coverage, and facial profile. The results were analyzed by Statistical Package for the Social Sciences (SPSS) software and the Chi-squared test was used to compare qualitative data. Results The results show that the prevalence of trauma was found to be 12.1%, and there was no disparity between government or private schools and urban and rural areas. There was no much sex predilection. High school children are more prone to TDI than primary school children. The most common place was found to be home, and the most common cause is unknown. Maxillary central incisors are the most commonly affected and enamel fracture is the most common fracture. Among the subjects with trauma, only 4.1% sought treatment. Conclusion The subjects with trauma in the present study are found to be having a positive association with risk factors, such as increased overjet, class II division 1 molar relationship, convex facial profile, and inadequate lip coverage. Evidence of a lower rate of treatment outcomes shows the need for increased awareness among parents, teachers, and healthcare providers and the elaboration of prevention strategies for TDI at the population level.

A bstract Aim To evaluate the effect of antioxidants on the shear bond strength of composite resin to bleached enamel. Materials and methods A total of 120 extracted permanent anterior teeth were split into four major groups, one among them being a control group. Group I (bleaching + without antioxidant), group II (bleaching + 10% sodium ascorbate), group III (bleaching + 5% grape seed extract), and group IV (bleaching + 5% pine bark extract). All of the groups were bleached using a gel containing 35% carbamide peroxide, and then they were divided into two subgroups depending on when the bonding operation was to be completed—subgroup A was done in 24 hours, while subgroup B took 3 weeks. The universal testing machine was used to measure the shear bond strength. Results Subgroup IA showed poor shear bond strength than other groups, there was no statistically significant difference between subgroup IB, IIA, and IVA. Subgroup IIIA showed the highest shear bond strength than the remaining groups. Between subgroups IIA and IIB, IIIA and IIIB, and IVA and IVB there was no statistically significant difference. This shows that delaying the bonding procedure for 3 weeks shows similar shear bond strength when compared to groups that were immediately bonded after antioxidant applying groups. Conclusion All the antioxidants’ immediate application could reverse compromised bond strength. Among them, 5% grape seed extract shows the highest increase in shear bond strength.
