The purpose of this study was to find out prevalence of peg-laterals and to evaluate the frequency of dental anomalies in Korean children with peg-laterals. For this study, panoramic radiographs of 3,278 patients (aged 7 to 15 years) from the Department of Pediatric Dentistry admitted from January, 2008 to January, 2013 were selected for an investigation on peg-laterals distribution. The prevalence of peg-laterals was 2.62% (86 subjects). Among the peg-laterals children, the distribution of associated dental anomalies were as follows: congenitally missing teeth (29.1%), dens invaginatus (19.8%), impacted teeth (12.8%), supernumerary teeth (9.3%), and transposition (4.7%). Due to this study showing frequent occurrences of peg-laterals with other dental anomalies, one suggestion is to consider such relationships before deciding on a diagnosis and treatment plan.
