Laser-assisted treatment of a dentigerous cyst: case report.

Dentigerous cysts are benign maxillary odontogenic cysts associated with the crown of an unerupted tooth. They can expand the cortical bone to such an extent that they cause displacement of teeth and root resorption in the adjacent teeth. The purpose of this report was to describe the clinical case of a dentigerous cyst in a mandibular permanent molar of a 6-year-old child.
