目的：探讨翻瓣手术中用无机三氧化矿物凝聚体（ mineral trioxide aggregate ，MTA）对不完全性牙根纵裂的裂纹进行充填的治疗效果。方法对6例不完全性牙根纵裂的患牙，采用翻瓣手术的方法，直视下暴露牙根纵裂面，清除炎性感染组织后，磨除纵裂纹，MTA充填，术后第3、6、12个月定期复查。结果6例患牙中，1例因牙根完全折裂在手术中拔除，其余5例完成手术。术后复查显示伤口愈合良好，患者无自觉症状，根尖及牙周低密度影逐渐消失。结论此手术方法保存不完全性牙根纵裂患牙取得了令人满意的疗效。

Objective To discuss the treatment effect of using mineral trioxide aggregate ( MTA) to fill the crack of incomplete verti-cal root fracture in periodontal flap surgery .Methods 6 teeth with incomplete vertical root fracture were made to undergo a periodontal flap surgery so as to expose the pattern of the root fracture .After the inflammatory tissues were removed ,the root fracture was abraded , and the fracture line was filled with MTA .Periodic review was done during the following 3rd,6th and 12th month.Results One tooth was extracted because of its complete root fracture in the surgery; the other 5 teeth underwent the surgery as planned .In the 3rd,6th and 12th months’follow-up,all the 5 cases showed clinical and radiographic success .Conclusions The present surgical approach for preserving teeth with incomplete vertical root fracture demonstrated satisfactory results regarding the clinical outcome .
