Unilateral Gemination of the Upper First Permanent Molar: A Rare Case Report

Abstract Gemination or a double tooth is a rare condition experienced in dental clinics, in which usually the tooth shows one root and two intertwined crowns. It is an incomplete separation for one tooth. The etiology of gemination is multifactorial, such as environmental factors, trauma, and genetics. The study aimed to find the prevalence rate of gemination in Karbala city population. In the present article, an orthopantomogram of 550 patients visiting the oral and maxillofacial private radiology clinic in Al-Mina Dental Center, Iraq/Karbala City was examined for the presence of tooth gemination. The results revealed that only one case of unilateral gemination of the upper first maxillary permanent molar in a male patient 32 years old was reported. The study concludes that the low prevalence rate of gemination confirms the role of racial factors.
