目的:分析乳牙根管治疗后反应。方法:对98例3~11岁乳牙病患儿采用第1次活髓乳牙、第2次死髓牙或活髓牙失活后的根管扩大术、第3次根管充填治疗,并对根管治疗效果进行分析。结果:98例乳牙根管治疗后反应Ⅲ类占86.84%,Ⅱ类占9.87%,Ⅰ类仅占3.29%,且经及时对症处理后很快消失。结论:乳牙根管治疗后Ⅰ类反应出现比例较小,因此乳牙根管治疗对于患病乳牙的稳固、行使正常的功能直至被继承恒牙替代是一个较好的治疗方法。
Objective: To analyze the post-root canal response of primary teeth. Methods: 98 cases of children aged 3 to 11 years with primary dental pulp deciduous teeth, the second dead tooth pulp or live tooth root canal inactivation after root canal augmentation, the third root canal filling treatment, and Root canal treatment effect analysis. Results: After treatment of 98 primary deciduous teeth, the reaction type Ⅲ accounted for 86.84%, class Ⅱ accounted for 9.87%, class Ⅰ accounted for only 3.29%, and disappeared rapidly after the symptomatic treatment. CONCLUSION: Type I response is relatively small after root canal treatment. Therefore, root canal therapy of deciduous teeth is a good treatment for the stabilization of diseased deciduous teeth and the normal function until the replacement of permanent teeth.
