“…Fusion is distinguished from gemination by the congenital absence of an adjacent tooth, and the location and the number of teeth in dentition [6]. Gemination or double teeth have a double normal width, which derived from the same dental follicle [7]. While fusion is de ned as an incomplete coalescence of two tooth buds that can develop one pulp chamber with con uent enamel and dentin or two separated pulp chambers with a union of dentin only [8].…”

Objective To report a developmental-related tooth that the mandibular first molar fused to the second molar with seven canals and treated with a conservative option. Methods CBCT images were used for analyzing the complex morphoanatomy in coronal and root canal systems. The tooth was isolated with a rubber dam and seven canal orifices were identified. Root canal treatment under a microscope was carried out. Results The tooth was diagnosed as an anomalous fused mandibular molar with chronic apical periodontitis and the root canal treatment was successful. Conclusions We reported a rare case of fusion involving permanent mandibular molars and CBCT is a critical aid in efficiently diagnosing and understanding such an anatomically abnormal tooth. Clinical Relevance This study suggests CBCT analysis is important for understanding the abnormal structure and guiding for treating such a malformed tooth before operation. This study also provides a rare and interesting case for endodontics.

“…9 This failed attempt may result in two crowns of the same size with normal dimensions, or one of the crowns is rudimentary. 9 Many theories have been proposed for the etiology of gemination, especially environmental factors, dental traumas, vitamin deficiencies, systemic diseases, and genetic predispositions. 11 The prevalence for fusion and gemination is low and mostly reported in the literature as 0.05 to 1%.…”

“…15 In single cases, cone-beam computed tomography (CBCT) is used for the diagnosis of double teeth and treatment planning. [4][5][6]9,15,16 For example, Buchanan et al concluded in a case of a 12-year-old girl with a double gemination that the use of three-dimensional (3D) imaging greatly aids treatment planning and communication with the patient in such uncommon and unusual cases. 4 Double teeth are not an exact dental diagnosis, but are often used as a catch-all term when the diagnosis is unclear.…”

“…A discussed cause is the close contact and pressure between two germs that can result in fusion. 2,9 The most commonly affected teeth are incisors in the upper jaw. 2 Gemination is defined as a single enlarged or joined (duplicated) tooth, with the number of teeth present being normal if the anomalous tooth is counted as one.…”

“…5 Clinically, gemination is indicated by a groove or depression in the crown of the tooth that delineates the two teeth. 9 This failed attempt may result in two crowns of the same size with normal dimensions, or one of the crowns is rudimentary. 9 Many theories have been proposed for the etiology of gemination, especially environmental factors, dental traumas, vitamin deficiencies, systemic diseases, and genetic predispositions.…”

Gemination of an Erupted Mandibular Third Molar: A Short Presentation of an Exceptionally Rare Clinical Occurrence

Double teeth, like fusions and geminations, are rare disorders of tooth development. In this short case presentation, we describe the unique appearance of a fully erupted mandibular wisdom tooth in a 72-year-old patient whose tooth exhibited gemination. This was possible because tooth 46 had to be removed from the patient at the age of 20 and the missing molar was not replaced. This geminated tooth of 48 had been in function for almost 50 years and finally had to be removed due to a periodontal inflammation. To the best of our knowledge, this is the first case presented of this dental anomaly for a fully erupted lower wisdom tooth.

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.

Endodontic management of a rare case of the geminated maxillary second molar tooth using CBCT

Abstract: This report illustrates a rare case of a geminated maxillary right second molar tooth using CBCT in a 23‐year‐old man with severe pain. Nonsurgical endodontic treatment was performed, which gave rise to an asymptomatic tooth at the 12‐month follow‐up.
