非う蝕性歯頸部病変（NCCL）の修復は、歯質の異なる接着特性、歯頸部の生体力学的側面、術野のアクセスや隔離の困難さなどから、レジン材料にとって大きな挑戦となる。さらに、NCCLは辺縁歯周組織が果たす役割を十分に理解した上でアプローチする必要がある。歯頸部病変が歯肉退縮を伴う場合、修復歯科学と歯周病学との相互作用が審美的かつ長期的な成功の鍵を握っている。本報告では、多発性歯肉退縮を伴うNCCLに対して、修復と歯周治療を組み合わせた治療を行い、12ヶ月間経過観察した症例を紹介する。

Restoration of non-carious cervical lesions (NCCLs) represents a major challenge for resin materials due to the different adhesive properties of the tooth structure, the biomechanical aspects of the cervical area, and the difficulties in the access and isolation of the operative field. Furthermore, NCCLs should be approached with a complete understanding of the role played by the marginal periodontal tissue. Whenever a cervical lesion is associated with a gingival recession, the interplay between restorative dentistry and periodontology is decisive for full esthetic and long-term success. A case report is presented dealing with the treatment of NCCLs associated with multiple gingival recessions using a combined restorative and periodontal treatment with a 12-month follow-up.
