OBJECTIVE: Unerupted tooth, also called impacted tooth by some authors, is a dental organ that, even when fully developed did not erupt at the regular time, lying inside the bone completely surrounded by bone tissue or bone and mucosal tissue. The unerupted canines study is very important in dentistry, since successful results depend on early diagnosis for proper treatment management, however, despite the importance of this issue, few studies were found in the literature.CASE DESCRPTION: This paper reported a clinical case of a 14-year-old female patient who had four canines in the mentonian region of the mandible surrounded by a dentigerous cyst. The patient underwent a surgical procedure under general anesthesia for the teeth and dentigerous cyst removal.
