Prevalence of mandibular anterior teeth crowding in mixed dentition subjects reporting to a university hospital in chennai city

Abstract

Crowding or deficiency in tooth size arch length is one of the most common reasons that people seek orthodontic treatment for themselves or their children. Diagnosis of this helps us determine the necessity for early interceptive orthodontic treatment. The aim of this study was to evaluate the prevalence of mandibular anterior teeth crowding in mixed dentition subjects among the South Indian population in patients visiting a private dental hospital from June 2019 to April 2020. The study population included orthodontic patients with crowding in mandibular anterior teeth, selected by non-probability purposive sampling. Data was collected and then subjected to statistical analysis. Out of 3652 patients aged between 6-12 years, 9.4% of the patients reported mandibular anterior teeth crowding. The results of the study were subjected to Chi-square tests. There was no significant association between mandibular anterior teeth crowding and gender (p value>0.05). There was significant association between mandibular anterior teeth crowding with age (p value<0.05). Mandibular anterior teeth crowding was commonly seen in subjects with Class I malocclusion. Within the limits of the study prevalence of mandibular anterior crowding was 9.4%. Mandibular anterior teeth crowding was significantly associated with age, but no association was found with gender.
