An Observational Study on the Prevalence of Supernumerary Teeth and associated complications in Children Aged 6–15 Years
Keywords:
Supernumerary teeth, complications of supernumerary teeth, prevalance of supernumerary teethAbstract
Introduction
Those teeth that are more than the average amount are referred to as supernumerary teeth. Between the two central incisors in the middle of the premaxilla are mesiodens, or unerupted supernumerary teeth. The occurrences are reported to be 0.3%–0.8% in the primary dentition and 1.5%–35% in the permanent dentition.The mesiodens, which is located in between the maxillary central incisors, is the most typical extra tooth. Although the primary cause of Supernumerary Teeth is unknown, various theories have been put out, and the most popular one is that the dental lamina's horizontal proliferation or hyperactivity is the primary cause of Supernumerary Teeth.
Materials and method
This retrospective observational study was conducted using archived patient records from Saveetha Dental College and Hospitals. Dental records of children aged 6–15 years who reported between January 2023 and December 2025 were reviewed. Data regarding age, gender, location of supernumerary teeth, morphology, eruption status, and associated complications were collected and analyzed using SPSS Version 23.0. Descriptive statistics and Chi-square tests were used for statistical analysis, with p < 0.05 considered statistically significant.
Result and discussion
The prevalence of Supernumerary Teeth was found to be 1.87% (17 out of 900 children), with 1.13% cases detected in group I and 2.6% cases detected in group II children. Out of 17 children with ST, two children had double supernumerary teeth, while 15 (group I = 4; group II = 10) had single Supernumerary Teeth. In contrast to permanent teeth, which most frequently exhibit Supernumerary Teeth in the central incisor region, primary teeth more frequently exhibit Supernumerary Teeth in the lateral incisor region.
Conclusion:
Supernumerary teeth are more frequent among males than females, more frequent in the upper premaxillary region, and more prevalent in permanent dentition. Complications associated with Supernumerary Teeth include impaction, delayed eruption, ectopic eruption, dental overcrowding, teeth spatial disorders, and formation of follicular cysts
