Statistically significant association was seen with supernumerary teeth (25%, p value=0.034) and congenitally missing teeth (37.5%, p value=0.034). Similarly, significant association (pvalue=0.004) was seen with the geographical area (Northern part of Khyber Pakhtunkhwa 75%, Central Khyber Pakhtunkhwa 12.5%, and Federally Administered Tribal Areas 12.5%).
