Abstract

A clinical survey of 1466 children of typical South African communities showed a prevalence rate of primary tooth trauma of 15%. Trauma was least common at age 1-2 years (10.7%) and most common at 4-5 years (20.6%). The commonest trauma seen was fracture of enamel only (71.8%) followed by fracture of dentine (11.2%), tooth loss (8.2%) and discolouration without other sign of injury (5.6%).
