The data obtained were subjected Chi-squared test to determine differences in the distribution of supernumerary teeth using SPSS version 20.0 software (IBM Corporation, USA). The result shows that the prevalence of supernumerary teeth was 5.2% in which the incisor presented 3.39% and the location was 90% (n=311) in the maxillary arch, while the eruption status was 35.8% (n=124) erupted.
