Dentigerous cysts, the most commonly occurring developmental cysts of the jaw, develop in association with impacted teeth.
However, in the absence of a syndrome, occurrence of bilateral dentigerous cystsis rare;approximately 23 cases have been described in the literature. Development of bilateral dentigerous cysts after the fi fth decade is extremely rare. We report on a rare case of bilateral non-syndromic dentigerous cysts associated with both mandibular third molars of a 49 year-old man.
