The Incidence and Correlation between Age and Tooth Aversion

Tooth avulsion is defined as the complete loss of a tooth or complete displacement of a tooth out of the alveolar bone socket as a result of an accident and represents a severe traumatic dental injury (TDI). Tooth avulsion mostly affects incisors in children and adolescents and is often associated with an unpredictable outcome and long-term treatment burden. After replantation of the tooth, the prognosis commonly remains uncertain. Replacement resorption or inflammatory resorption are probable adverse outcomes in comparison to the more favorable functional healing. Tooth resorption mostly appears in cases, where connective tissue between the root cementum surface and the alveolar bone, the periodontal ligament (PDL) is severely damaged.The aim of the study is to compare the incidence and association of tooth avulsion and age. The retrospective study examined the records of 86,000 patients from January 2020 to April 2021 in which 10 patients who had tooth avulsion underwent treatment for it and who belonged to the age group 3 to 5 years, 6 to 11 years, 12 to 18 years at a university dental hospital in Chennai were shortlisted based on the inclusion and exclusion criteria. The data was then entered into SPSS software for statistical analysis. From this study, it was found that the incidence of tooth avulsion in the age group of 3 to 5-year-olds is 34%, 6 to 11-year-olds is 30% and 12 to 18-year-olds is 36%. From the present study, we can conclude that the incidence and association of tooth avulsion from the given sample is low and that tooth avulsion remains a severe dental injury with an unpredictable prognosis, which demands new fundamental research aiming to maintain or regenerate the PDL after tooth avulsion.
