- Abstract -

Disturbance in tooth development leads to various dental anomalies, including tooth agenesis, or congenital absence of primary and / or permanent teeth. Oligodontia is a rare condition that can occur in association with genetic syndromes, or as a non-syndromic isolated trait 2. Several studies have shown that gene MSX1 and PAX9 play a role in early teeth development 7, 10.

We present a case where the clinical and radiographic examination determined that 14 permanent teeth are present, while 14 permanent teeth are absent; except for third molars. There was no history of previous extractions, a systemic disease or syndrome. In our case, cytogenetic analysis exhibits the fragile site at 1p36 chromosome.

A multidisciplinary approach is essential to achieve better aesthetics and function in such cases.

Key words: oligodontia, nonsyndromic, genetics, cytogenetic, chromosome, multidisciplinary approach.
