摘要
目的:探讨127颗隐裂牙的特征及临床疗效。方法:127颗诊断为牙隐裂的患者年龄、性别、牙位、隐裂线走向,临床症状和体征被记录,降低咬合并根据牙髓状态分别采用树脂充填、根管治疗加全冠修复的治疗措施,并进行6个月的临床疗效随访。结果:40～60岁间患者牙隐裂发生率最高,男女无明显差别,以上颌第一磨牙多见,隐裂线多为近远中向。牙髓活力正常组经治疗后成功率78.3%,好转率6.5%,失败率为15.2%,有效率为84.8%;不可复性牙髓炎组治疗后成功率90.1%,好转率6.2%,失败率3.7%,有效率达96.3%。结论:对牙隐裂进行合理的诊断和治疗能有效保留患牙,恢复咬合功能。
Objective： To find out the characteristic features of 127 cracked teeth and explore clinical treatment and effectiveness. Methods： Each tooth that was identified as a cracked tooth was recorded and analyzed in terms of the age and gender, the position in the mouth, the location of crack--line, the clinic signs and symptoms. After reducing the cusp height, cases with the normal pulpal status were prepared and restored with resin; cases with irreversi- ble pulpitis were done with root canal treatment and crown restoration. The patients were followed up for 6 months and the treatment effectiveness was reviewed. Results： The most prevalent age was in those 40 60 years of age and the prevalence was similar in men and women. Cracked teeth were found most frequently in the maxillary molars and 90.5% of the cracked teeth were observed in the mesiodistal direction. In the teeth with normal pulpal status, 78.3% were successfully, 6.5% were better, while 15.2% were failed. The effectiveness was 84.8%. 90. 1% of cases with irreversible pulpitis were successfully, 6.2% were better and the rate of failure was 3.7%, the effective ness reached 96.3 %. Conclusion： Reasonable clinical diagnosis and treatment can contribute to the retention of the cracked teeth and restore the occlusion.
