AIM: To investigate the characteristics and distribution of premaxillary supernumerary teeth affecting primary and mixed dentitions in Indian children.
METHODS: This retrospective analysis included 11 200 children, aged 3-12 years, who attended a pediatric dental clinic for dental care during the period 2007-2010. The children were divided into group I (aged 3-6 years) and group II (aged 7-12 years), and data regarding maxillary anterior supernumerary teeth, diagnosed both as isolated and/or as unexpected findings during routine clinical and radiological examinations, were gathered. Pearson's χ(2) -test, with a 0.05 level of significance, was used for the analysis.
RESULTS: The overall prevalence of premaxillary supernumerary teeth in primary and mixed dentitions was 1.9%. Single supernumerary teeth (84.9%) and conical morphology (68.7%) were commonly seen in both groups. The most common sagittal position was palatal (92.3%) among both erupted and impacted maxillary anterior supernumerary teeth.
CONCLUSION: The prevalence of premaxillary supernumerary teeth in Indian children found in this study was 1.9%, with an overall male to female ratio of 1.7:1. Single supernumerary teeth, conical morphology, and erupted supernumerary teeth were the most commonly seen. Supernumerary teeth associated with clinical complications were relatively low (48%), and axial rotation or displacement of maxillary incisors was the most common sequelae.
