摘要： 目的: 通过对临床上非外伤性隐裂牙的临床特征进行分析并对其锥形束CT(Cone beam computed tomography, CBCT)的影像学表现进行总结。方法: 对105名患者的105颗明确冠隐裂牙的临床特征及CBCT影像学特征进行统计,收集临床资料包括患者的性别、年龄、牙位,同时对其CBCT上牙根折裂情况,牙槽骨及根尖周骨质吸收情况进行评价和统计。结果: 105例患者中,男性49.52%,女性50.48%;在50岁之前,随着年龄增加,隐裂牙发生比例增加,其中41~50岁发生率最高(34.29%),之后下降。105例隐裂牙中有5例发生在前磨牙区,其余均发生在磨牙区,其中第一磨牙发生率最高(59.05%)。105颗隐裂牙,CBCT检查有16颗(15.24%)可观察到牙根存在不完全折裂,仅4颗(3.81%)可见牙根完全折裂。其余85颗(80.95%)隐裂牙牙根未见明显异常。结论: 隐裂牙好发于上下颌第一磨牙,CBCT检测下大多数的冠隐裂牙并没有发生牙根折裂。

Abstract: Objective: To study the clinic features and summarize the radiographic manifestation on the CBCT images of non-traumatic cracked teeth. Methods: 105 patients with 105 cracked teeth were collected in this study. The sex, age and position were evaluated on the CBCT images. Results: Of the 105 patients, 50.48% was females and 49.52% was male. The incidence of cracked tooth increased with age before 50 years old, the highest incidence (34.29%) was between 41 and 50 years old. 5 cases was located in the premolar region, the others all located in molar region. The first molar had the highest incidence (59.05%). Of 105 cracked teeth, 16 (15.24%) teeth presented incomplete root fracture and 4 (3.81%) presented complete root fracture on CBCT images. The others had no obvious root abnormality. Conclusion: Cracked teeth are often located in the first molar region. Most of the cracked teeth involved crown but not root fracture on CBCT images.
