Abstract

20 radicular cysts of primary teeth mimicking dentigerous cyst were reviewed. The following results were obtained. 1. The patients' age ranged from 7 to 14 years. Males(60%) were more involved than females(40%). 2. The mandible(85%) was affected more frequently than the maxilla(15%) The mandibular deciduous molar area(80%) was the most frequently involved. 3. The diameter of the cyst varied from 10 to 30㎜. 55% of permanent successors showed underdeveloped roots less than one-third. 4. The etiologic factors were pulp-treated teeth(65%), severe caries (20%), trauma(10%), deep amalgam filling(5%).
