Dentigerous cyst of impacted canine

Dentigerous cysts are most common bony lesions of oral cavity. Most of cases are reported in second and third decade of life, and it shows slight male predilection. (3:2) Dentigerous cysts are commonly seen in mandibular third molar region and maxillary canine region, as they are the most commonly impacted teeth. Radiographic findings cannot be considered as ultimate tool to diagnose dentigerous cyst because odontogenic keratocysts, Unilocular ameloblastomas, and many other tumors show similar radiological findings. Thus, histopathological examination holds important in its diagnosis. Cyst size and site, involvement of dentition and surrounding structures should be considered while treatment planning. On the basis of these criteria, different treatment modalities should be chosen. This includes cyst enucleation and extraction of impacted tooth, cyst enucleation and preservation of impacted tooth or decompression with surgical access. We are presenting a case of dentigerous cyst at maxillary canine region.
