摘　　要：目的探讨隐裂牙的临床特点、治疗方法及其预后。方法 207例隐裂牙按病情发展程度分为牙髓正常隐裂牙组(A组)73例和牙髓异常隐裂牙组(B组)134例,按照隐裂牙治疗原则,结合患者身体条件和患者意愿选择调、充填或全冠修复等治疗方法,不同治疗方法2年成功率应用χ2检验进行统计学分析。结果 A组中全冠修复2年成功率为94%(30/32),高于调或充填治疗方法,差异有统计学意义(χ2=21.684,P<0.05)。B组根管治疗后全冠修复成功率为94%(78/83),高于根管治疗后充填治疗方法,差异有统计学意义(χ2=7.759,P<0.05)。结论全冠修复是防止隐裂牙发生牙体、牙髓、牙周各种并发症的有效治疗方法。Objective To explore the clinical feature, treatment and prognosis of incompletely fractured teeth. Methods Two hundred and seven incompletely fractured teeth were divided into group A including 73 teeth with normal pulp and group B including 134 teeth with abnormal pulp in accordance with the degree of fracture advancing. Treatments including occlusal adjustment, filling restoration and full crown restoration were selected according to principles of treating incompletely fractured teeth in combination of physical conditions and wills of patients. Success rates of treatments for 2 years were analyzed statistically by χ^2 test. Results The success rate of full crown restoration in group A for 2 years was 94 % （30/32）, which was statistically higher than those of occlusal adjustment or filling restoration （χ^2= 21. 684,P〈0.05）, and the success rate of full crown restoration in group B was 94% （78/83）, which was statistically higher than those of filling restoration after root canal therapy （χ^22 =7. 759,P〈0.05）. Conclusion Full crown restoration is the effective treatment for incompletely fractured teethavoiding complications, which occurring to tooth hard tissue, pulp and periodontal tissue.
