【摘要】：目的：观察连续波热牙胶充填技术对侧支根管充填的疗效。方法：收集在吉林大学口腔医院牙体牙髓病科内需要根管治疗术的30例的病例。患牙30颗，年龄18-60岁，男15例，女15例；确认无明显的瘘管和根尖发育完成，无根尖吸收及根折之后进行实验。开髓之前用橡皮障隔水，然后临床常规的方法开髓及成形洞型，并使用拔髓针进行拔髓，揭髓室顶及冲洗使术者视野清晰。探查根管口位置及其数目，使用10#C型锉小幅度提拉疏通根管，使用根管长度测量仪器与X线片结合距根尖1mm左右处为确定工作长度。使用乙二胺四乙酸（EDTA）与PROTAPER镍钛器结合预备根管至F2，预备过程中用０.9%生理盐水和1%次氯酸钠交替反复冲洗，预备后使用超声荡洗仪清理根管内的玷污层及感染物；隔湿及干燥后，，使用樟苯酚棉捻封药，并使用暂封材料暂封窝洞，一周后，去除暂封材料后将主牙胶尖蘸一小层根管封闭剂，按工作长度缓慢插入根管，使用电携热器切除距根尖3-4mm处左右的牙胶尖，再加使用热牙胶注射仪注射于根中上段，同时使用垂直加压器严密加压封闭根管。根管充填完成后，观察X片上的根管及侧支根管充填的效果。结果：在根管治疗30个病例中，用连续波热牙胶垂直充填技术充填的X线片全都显示良好的封闭效果，其中6例均可发现侧支根管。结论：Protaper镍钛器械有利于械形成良好连续的锥度，根管冲洗的方式和根管冲洗剂的选择对侧支根管有影响，连续波热牙胶垂直充填技术对侧支根管有充填效果良好的封闭性。
[Abstract]:Objective: to observe the effect of continuous wave hot gum filling on lateral branch root canal filling. Methods: a total of 30 patients with dental pulp disease (Kone), aged 18-60 years, 15 males and 15 females, who needed root canal therapy, were collected in Jilin University Stomatology Hospital. It was confirmed that there was no obvious fistula and apical development, no apical absorption and root fracture were carried out. Before pulp opening, rubber barrier was used to isolate water, then clinical routine methods were used to open and shape the cavity, and pulpooning needle was used to pull out the pulp. To explore the location and number of root canal orifice, 10 #C file was used to dredge the root canal. The length of root canal was determined by measuring the length of root canal with X-ray film and about 1 mm from the root tip. The root canal to F2 was prepared by the combination of ethylenediamine tetraacetic acid (EDTA) and PROTAPER nickel titanium apparatus. During preparation, 0.9% normal saline and 1% sodium hypochlorite were alternately rinsed repeatedly. After preparation, the smear layer and infection in root canal were cleaned by ultrasonic washing instrument. After wetting and drying, anisodonol cotton was used to seal the root canal, and the temporary sealing material was used to seal the hole. After a week, the main gum tip was dipped in a small layer of root canal sealant and inserted into the root canal slowly according to the working length. The electric calorimeter was used to remove the gum tip about 3 to 4 mm from the root tip, and then the hot dental glue injector was used to inject the root canal into the upper and middle part of the root. At the same time, the root canal was tightly pressurized and sealed by using the vertical pressurizer. After the root canal filling was completed, the root canal filling was completed. To observe the effect of root canal and lateral branch root canal filling on X-ray. Results: in 30 cases of root canal therapy, all the X-ray films filled with continuous wave hot gum vertical filling showed good sealing effect, of which 6 cases could find lateral branch root canal. Conclusion the ratio Protaper Ni-Ti instrument is beneficial to the formation of a good continuous taper. The way of root canal washing and the choice of root canal washing agent have an effect on the lateral branch root canal. Continuous wave hot gum vertical filling has good sealing effect on lateral branch root canal.
