Dentigerous cyst involving mandibular third molar: Conservative treatment with radiologic follow-up and review of literature

Dentigerous cyst is the second most common odontogenic cyst and constitutes around 20-24% of all the odontogenic cysts involving the jaws. Usually, these cysts remain asymptomatic and rarely cause enlargement and displacement of associated tooth. In this paper, we present a case of a displaced mandibular third molar, which was associated with a large dentigerous cyst. A conservative treatment modality was adopted with a 2 year radiographic follow-up of the patient. A brief review of previously reported cases with dentigerous cyst causing displacement of the mandibular impacted third molars is also discussed, highlighting the treatment modality followed in all these cases.
