Chulalongkorn University Dental Journal

Objective The aim of this study was to determine the prevalence of permanent premolars with Dens evaginatus, relationships between age and the stage of attrition and between the anomaly and sex. Materials and methods 1,141 schoolchildren in Mathayomsuksa 1-3 of Ratchavinitbangkhaepankham school (602 males and 539 females) were examined for the presence of Dens evaginatus and status of anomaly in all erupting permanent premolars. Data were statistically analyzed using SPSS at a significant level of P<0.05. Results Dens evaginatus was found in 21 students (1.8 percent). The anomaly mostly occurred in mandibular premolars. There was no significant relationship between Dens evaginatus and sex. The prevalence of Dens evaginatus was significantly associated with age. There was a statistically significant difference between 11 - 12 year - old and 13 - 17 year - old children. (P=0.004) Conclusion The appropriate age for management of Dens evaginatus should be at 12 years. Successful management of Dens evaginatus depends on the likelihood of early diagnosis and intervention. This study suggests that management of Dens evaginatus initiate as soon as premolars erupt.
