title: Unusual case of concomitant occurrence of Tessier's number 7 cleft and dentigerous cyst.
abstract: Dentigerous cysts are commonly encountered associated with impacted teeth; however the exact histogenesis of these cysts is not known even though numerous theories have been proposed. Majority of the maxillary cysts arise as a result of defect in the embryonal development, which can be either abnormal fusion of facial processes or as a result of abnormality in the development of dental follicle. Congenital Tessier's number 7 unilateral facial cleft is a rare anomaly, which arises as a result of defect in the fusion of facial processes. We report an unusual case of concomitant occurrence of Tesssier's number 7 cleft and maxillary dentigerous cyst in 11-year-old child.
