Abstract

OBJECTIVE: To observe the pattern of crown fractures in schoolchildren aged 9-18 years. METHODOLOGY: Nine public and 4 private Primary to higher secondary schools of KhairpurMirs District, Sindh, were included in this cross sectional study.Selected study participants were examined with disposable tongue spatula under daylight by a single examiner. Data related to gender, age, tooth involved, number of teethinvolved, type of tissue injuryand treatment taken for coronal trauma were recorded. RESULTS: The male/female ratio was recorded as 2:1. Atotal of 4.32% males and 3.28% females exhibited crown fractures.Central incisor was the most affected tooth (64.47%) followed by maxillary lateral incisor (10.52%), mandibular central incisor (7.89%), mandibular lateral incisor (5.26%), maxillary canine (2.63%) and mandibular canine (1.31%). In addition, single tooth trauma was identified in most of the cases. Fracture observed in enamel was 52.6%, which was significantly greater than fracture in enamel & dentine with or without pulp involvement. CONCLUSION: An overall 4% occurrence of coronal trauma among 9-18 year-old students of district khairpurMirs, Sindh, Pakistan was identified. Maxillary central incisor and fracture involving enamel only were the most common findings.
