Dentigerous cysts, the most commonly occurring developmental cysts of the jaw, develop in association with impacted teeth. Most dentigerous cysts are solitary. Multiple dentigerous cysts are rare and generally occur in association with a developmental syndrome or systemic disease, such as mucopolysaccharidosis and cleidocranial dysplasia. However, in the absence of a syndrome, occurrence of multiple dentigerous cysts is rare. Development of multiple dentigerous cysts on first molars extremely rare. The purpose of this paper was to report on a nonsyndromic, 8-year-old boy who presented multiple dentigerous cysts on first molars.
