Abstract:

Dental fusion is a rare developmental anomaly, which stems from embryogenic union of 2 teeth originating from two different germs. These teeth also tend to be greatly predisposed to caries and periodontal disease and in some cases, endodontic treatment may be complicated. A 15-year-old male patient was referred to our clinic with the main complaint of pain in the mandibulary incissor region. Clinic and radiographic examinations revealed that two mandibulary permanent central incissors were fused. The fused tooth was devital and had a periapical lesion. Therefore root channel treatment was applied primarily. During the treatment, it was concluded that a surgical approach is required. The fused tooth was extracted and its crown and root was reshaped. After the curettage of periapical granulation tissue, the tooth was replanted with otogen bone graft. After 12 months of follow-up period, it was seen that the tooth was in function and periapical lesion was healed.
