老年患者钙化根管的预备

Root canal preparation of calcified root canals in the elderly patients

目的:观察老年人根管钙化情况,总结高校社区医院对老年患者钙化根管的治疗方法。方法:选择60-72岁老年患者的148个钙化根管,在EyeMag放大镜下,分别采用低速球钻或超声器械去除髓室内钙化物,C型先锋锉蘸取Glyde凝胶进行根管疏通,术中记录根管钙化情况和疏通效果,最后完成根管预备、消毒和充填。结果:老年人钙化根管多见于上颌第一磨牙,前牙、前磨牙、磨牙疏通成功率分别为:91.67%,72.73%,60.80%,前牙组疏通成功率高于磨牙组(χ2=4.50,P<0.05);根管冠方1/3和根中1/3较易发生钙化,且钙化的疏通成功率明显高于根尖1/3(χ2=19.33,P<0.05)。结论:针对老年人钙化根管的治疗,临床医生要有足够的细心、耐心和信心,灵活的综合运用现有的各种治疗器械和设备,能够取得较好的治疗效果。

Objective： To observe the condition of the root canal calcification of the elderly patients and sum up the therapy for elderly patients with calcified root canal in community hospital. Methods： 148 calcified root canals were selected form the age of 60-72 elderly patients. Under the EyeMag magnifying glass, low speed ball drill or ultrasonic instrument were used to remove the pulp chamber calcifications. Then C-Pilot files dipped into Glyde gel were used to unchoke root canals. While the condition of the root canal calcification and dredge effect were recorded during the operation. Finally root canal preparation, disinfection and filling were performed in sequence. Results：Calcified root canals of the elderly people were usually happened in maxillary first molar, anterior teeth, premolar and the success rate of molar dredge were 91.67%, 72.73%and 60.80%respectively, which showed that the dredge success rate of anterior teeth group was higher than molar group（χ2=4.02, P〈0.05）. 1/3 coronal segments of root canal and 1/3 middle segments of root canal were prone to calcify, whose dredge success rate was obviously higher than that of lower segment （ χ2=19.33, P〈0.05）. Conclusion：Regarding the treatment of the elderly patients’ calcified root canals, clinical dentists should be careful, patient and confident, using various treatment instruments and equipments flexibly and comprehensively, which could achieve favorable treatment results.
