Odontoma is an odontogenic lesion with epithelial and mesenchymal origin and is composed of differentiated dental parts. Than because of abnormal organization of mature tissues. It seems that it is a hamartoma rather than real tumor. Odontoma is seen in two types of compound & complex.Out of 57 studied cases, 31 cases (54.2%) were of complex type 12 cases (21 %) were compound & 8 cases were of cystic. The age of incidence ranged from 5.5 to 68 years. The mean age in complex odontoma was 27 years & compound type was 19 years. There was no significant difference regarding the sex in the complex type. In compound odontoma women were affected 2 times more than means.Complex type are found in mandibular posterior era ereas more and compound type in anterior regions .In this studied found 12 cases impaction teeth.

Odontomas are benign tumors of odontogenic origin characterized by their slow growth. They are considered to be a common type of odontogenic tumor, but rarely occur in the primary dentition.The etiology of odontomas is unknown, although local trauma, infection and genetic factors have been suggested. Odontomas often cause disturbances in the eruption of teeth such as, impaction or delayed eruption, and retention of primary teeth and abnormalities in the position of teeth such as tipping or displacement of adjacent teeth. In this paper, a case of unerupted right mandibular primary cuspid in a 5 years old girl due to the presence of a compound odontoma is presented.
