歯の癒合は、乳歯と永久歯の両方に影響を及ぼす可能性のある発達性のある歯の異常です。このような異常は、虫歯や歯周病、さらには審美性の障害などの問題を引き起こす可能性があり、介入が必要となる。今回の症例では、若い患者さんが矯正治療の一環として両側の下顎融合歯の管理のために歯周病クリニックに紹介されました。右下の歯は頸部のみの不完全融合であった．左下の2本の歯は歯冠から頂点まで完全に融合していた。右の癒合歯は外科的切除を行い，左の癒合歯はそのままであった．その後，上下の歯列弓を整列させるための矯正治療を行った．患者は治療結果に満足していた。

Tooth fusion is a developmental dental anomaly that may affect both the deciduous and permanent dentition. Such anomalies may cause problems such as caries, periodontal disease or even esthetic impairments, which will require intervention. In the present case, a young patient was referred to the periodontal clinic for management of bilateral mandibular fused teeth as part of the orthodontic treatment. On the lower right, the teeth involved were incompletely fused involving only the cervical region. On the lower left, the two teeth were completely fused from the crown to the apex. A surgical resection was carried out on the fused teeth on the right, while the fused teeth on the left was undisturbed. Orthodontic treatment was later carried out to align both the upper and lower arch. The patient was satisfied with treatment outcome.
