ABSTRACT

The purpose of this study was to find out prevalence of peg-laterals and to evaluate the frequency of dentalanomalies in Korean children with peg-laterals. For this study, panoramic radiographs of 3,278 patients (aged 7to 15 years) from the Department of Pediatric Dentistry admitted from January, 2008 to January, 2013 wereselected for an investigation on peg-laterals distribution. The prevalence of peg-laterals was 2.62% (86 subjects). Among the peg-laterals children, the distribution ofassociated 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 isto consider such relationships before deciding on a diagnosis and treatment plan.
