ABSTRACT

Supernumerary teeth are those teeth that occur in addition to the normal set of dentition. Based on the appearance and region of occurrence, they’re of different types such as mesiodens, parapremolar, paramolar and distomolar. The aim of the study was to determine the prevalence of supernumerary teeth among dental patients and to assess the gender based differences. The retrospective study involved analysis of case records of patients with supernumerary teeth and assessment based on the parameters - type, quadrant involved gender, age, and eruption status. Using SPSS Version 20.0, categorical variables were expressed as frequency and percentage, continuous variables as mean and SD; and Chi-square test was used to determine the association between categorical variables. A p-value <0.05 was considered statistically significant. The sample size of the study was 69. The overall prevalence of supernumerary teeth is 0.17% with male : female ratio of 3.31 : 1. Mesiodens showed highest prevalence among all types (36.2%). Among quadrants, the 2nd quadrant had the highest prevalence of supernumerary teeth (31.9%). The association between gender and type of supernumerary teeth with p-value 0.027 and quadrant and type of supernumerary teeth with p-value 0.001 was statistically significant. According to our study it can be concluded that in the South Indian population, prevalence of supernumerary teeth was reportedly higher in males than in females with mesiodens being the most common type. A statistically significant association between gender and the type of supernumerary teeth; and quadrant and type of supernumerary teeth was observed.
