Rotary root canal instrumentation may be indicated for utilization in primary teeth, for enhancing root canal preparation and good quality of root canal filling.
It can be concluded that the use of antioxidant before bonding procedures on bleached enamel completely neutralizes the deleterious effects of bleaching and increases the bond strength significantly.
BACKGROUND:Although numerous studies have documented malocclusion in various age groups in India, the literature on the prevalence of malocclusion in mixed dentition is scanty. Dental caries is another most common condition affecting the general health. However, its association with malocclusion in mixed dentition is not well known.AIM:The purpose of this study was to establish the prevalence of malocclusion and its association with caries experience in 8–9-year-old children of Davangere city, South Indian region.SETTING AND DESIGN:The study design was a cross-sectional survey.MATERIALS AND METHODS:A total of 800 children from 350 schools (both males and females) were randomly selected for the study. t-test and Chi-square test were used for statistical analysis.RESULTS:The overall prevalence of malocclusion among 8–9-year-old children was 40.9%. The most prevalent malocclusion was crowding (11.5%), followed by excessive overjet (9.4%), deep bite (6.8%), spacing (6.5%), crossbite (4.5%), and open bite (3.2%). Class I molar relationship prevailed in 95.5% of children.CONCLUSION:The prevalence of malocclusion in our study was in accordance with the other studies reported in India, which ranged from 19.6% to 90%. Furthermore, correlation of malocclusion and dental caries in the primary dentition, although nonsignificant, presented children with malocclusion to have a higher caries experience than children without malocclusion.
Garre's sclerosing osteomyelitis is a kind of chronic osteomyelitis that is mainly seen in children and adolescents. It was formerly documented only in long bones, particularly tibia. Proliferative osteomyelitis of the jaw was described only in the late 1970s. Since then, this clinical entity is well illustrated in dental literature and is frequently linked with an odontogenic infection, mainly involving permanent teeth. This article describes an atypical manifestation of Garre's osteomyelitis of the mandible in a 7-year-old-girl, which was a result of infection of primary mandibular first molar. Extraction of the primary right first molar and antibiotic treatment resulted in complete healing, clinically and radiologically, after 6 months.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
