PYRAMIDAL MOLAR ROOTS AND CANINE-LIKE DENTAL MORPHOLOGIC FEATURES IN MULTIPLE FAMILY MEMBERS - A CASE-REPORT

We report on three cases of unusual dental morphologic characteristics with pyramidal-shaped premolars and fused molar roots occurring in tw o generations. The dental abnormalities were hereditary in nature with morphologic features similar to those described by others. The featur es described in the literature were inherited in a pattern suggestive of a polygenic system with incomplete penetrance, although autosomal d ominant inheritance with variable expression was possible. The present cases are found in a fashion suggestive of an autosomal dominant inhe ritance pattern, bur insufficient evidence is available to state this for certain. In this case report, we describe a family with the previo usly slated anomalies and discuss potential casuses for their conditio n as well as their clinical relevance.
