Objective The purpose of this study was to investigate the incidence of dentigerous cysts associated
with impacted mandibular third molars for routine prophylactic removal.
Materials and methods Pathological conditions of cystic like soft tissue attached to the cervical
surface of impacted mandibular third molars which were removed from 90 patients were studied.
Results The incidence of dentigerous cyst arising from impacted mandibular third molars was 52.2%
and of compatible with dentigerous cyst was 18.9%.
Conclusion Impacted mandibular third molars should be removed for preventing pathological changes
of pericoronal tissues.
