ABSTRACT
 Objective: Fusion and gemination are developmental dental anomalies. The aim of this study was to determine the prevalence, localization, distribution according to age and gender of double teeth (fusion and gemination) in permanent dentition. Material and Methods: The presence of a fusion and/or gemination in patients admitted to the Department of Oral and Maxillofacial Radiology for dental examination was investigated. Diagnoses of fusion and gemination were done by clinic and radiographic examination. The incidence, age, gender and upper and lower jaw localization were examined. Results: A total of 32 double teeth were detected in 30 patients after clinical and radiological examination, and the prevalence was found as 0.47%. Fusion was found in 22 patients, gemination was in 8 patients. Fusion was seen in two patients bilaterally. Fourteen (43.8%) cases were in the upper jaws and 18 (56.2%) cases were in the lower jaws. Mandibular and maxillary molars were the most commonly affected teeth (n:21, 65.6%). Conclusion: Fusion and gemination are uncommon dental anomalies. A careful clinical and radiological examination is important in the diagnosis of double teeth. Early diagnosis of these teeth is important to prevent possible complications. It will also facilitate treatment procedures such as endodontic, orthodontic or surgery to be performed by the dentist.

Keywords: Fused teeth; permanent dentition; diagnosis; dental radiography
ÖZET
 Amaç: Füzyon ve geminasyon gelişimsel dental anomalilerdir. Bu çalışmanın amacı, daimî dentisyonda ikiz diş (füzyon ve geminasyon) prevalansını, lokalizasyonunu, yaş ve cinsiyete göre dağılımını değerlendirmektir. Gereç ve Yöntemler: Dental muayene için Ağız, Diş ve Çene Radyolojisi kliniğine başvuran hastalarda füzyon ve/veya geminasyon varlığı araştırıldı. Füzyon ve geminasyon tanısı klinik ve radyografik muayene ile konuldu. Yaş, cinsiyet, üst ve alt çenelerdeki lokalizasyonları, görülme sıklıkları değerlendirilmiştir. Bulgular: Klinik ve radyolojik muayeneden sonra 30 hastada toplam 32 ikiz diş tespit edildi ve prevalansı %0,47 olarak bulundu. 22 hastada füzyon ve 8 hastada geminasyon belirlendi. İki hastada bilateral olarak füzyon izlendi. Üst çenede 14 (%43,8) vakada, alt çenede 18 (%56,2) vakada belirlendi. Mandibular ve maksiller molarlar en çok etkilenen dişlerdi (n: 21, %65,6). Sonuç: Füzyon ve geminasyon oldukça nadir görülen dental anomalilerdir. Çift dişlerin tanısında dikkatli bir klinik ve radyolojik muayene önemlidir. Bu dişlerin erken tanısı olası komplikasyonlarının önlenmesi açısından önemlidir. Hekimin uygulayacağı endodontik, ortodontik ya da cerrahi gibi tedavi prosedürlerini de kolaylaştıracaktır.
