Effects of root separating and core-post crown in the treatment of mandibular first molar with root furcation involvement

The mandibular first molars with degree Ⅱ-Ⅲ root furcation involvement were treated with early root separating followed by root canal trearapy and periodontic treatment,finally by core-post crown restoration.After the treatment,all molars immediately had the masticatory function.12 months after treatment the teeth could function as well as denture prosthesis.The results showed that early root separating and core-post crown can be used to treat the mandibular molar with root furcation involvement.More attention should be paid for indication selection,the time of root separating and core-post crown preparation and occlusional adjustment.
