摘　　要：目的探讨牙隐裂病因及其治疗方法。方法以135例患者的隐裂牙(共176颗)为研究对象,对其牙位、发病年龄及病因进行分析。结果牙隐裂好发于30～72岁,以上颌第一磨牙近中腭尖最为多见。对135例176颗隐裂牙综合治疗成功131颗,改善29颗,失败16颗,治疗有效率为90.9%。牙齿的薄弱结构和发育缺陷是牙隐裂发生的内在条件,牙尖斜面是易感因素,而创伤性牙合力是重要的致病因素。结论牙隐裂治疗的关键是早发现、早诊断,对于伴发牙髓和根尖周疾病的隐裂牙对其根管治疗后行全冠修复是非常有效的治疗方法。Objective To explore the etiology and treatment of cracked teeth. Methods Totally 135 patients （175 cracked teeth） were involved in this study to analyze the position of teeth,age at disease onset and etiology. Results The cracked teeth usu- ally occurred in 30- 72 years old and the predilection site was mesio-palatal cusp of maxillary first molar. After comprehensive treatment,the results were satisfactory in 131 teeth,improved in 29 teeth,and failure in 16 teeth. The effective rate was 90.9%. The weak structure and developmental defect were internal conditions of cracked teeth,cant of dental cusp was the risk factor,and trau- matic occlusal force was an important etiological factor. Conclusion The diagnosis at early stage is crucial for the treatment of cracked teeth. Complete coronal restoration after root canal therapy is very effective for the cracked teeth combined with pulpal and periapical diseases.
