第二磨牙远中根面龋伴牙周牙髓联合病变意向性牙再植的临床考量OA

The second molars often develop distal root surface caries due to the impaction of the third molars,which subsequently induces periodontal-endodontic lesions.Clinical root canal treatment for such cases faces numerous chal-lenges,including limited operating space,complex root canal anatomy,difficulty in repairing subgingival caries,and low cure rates for periodontal lesions.These factors often lead to complex procedures and poor prognosis in conventional en-dodontic treatments.Intentional replantation,as a last-resort tooth-saving technique,has gradually been applied to treat complex and refractory endodontic periapical diseases given its simplicity,thorough removal of caries,and simultaneous management of periodontal lesions.However,its clini-cal application requires careful consideration of the ana-tomical features of the second molars,the characteristics of caries and periodontal lesions,and the key points of surgical procedures.This study analyzes these aspects one by one and provides a comprehensive review to of-fer a reference for the clinical treatment of periodontal-endodontic lesions in the second molars with root damage via in-tentional replantation.
