有症状不可复性牙髓炎活髓保存的短期疗效观察

目的:探索性研究有症状不可复性牙髓炎能否采取活髓保存的治疗方式，同时与可复性牙髓炎保髓治疗比较3个月的短期疗效。方法:选择因龋病引起的可复性牙髓炎18例和有症状不可复性牙髓炎22例，共40颗磨牙，均采取活髓保存的治疗方式，比较3个月的短期疗效。结果:18例可复性牙髓炎组中，14例保髓治疗成功，成功率达77.8%；22例有症状不可复性牙髓炎组中，20例保髓成功，成功率达90.9%，比较两组之间3个月的短期疗效无统计学差异（P> 0.05）。结论:有症状不可复性牙髓炎可尝试采取活髄保存的治疗方式与可复性牙髓炎保髓相比3个月的短期疗效未见明显差别。

Observation of the short-term curative effect of Vital pulp therapy on irreversible pulpitis taking vital pulp therapy

Objective: To explore if the symptomatic irreversible pulpitis could be achieved vital pulp therapy, and the short-term curative effect compared with reversible pulpitis. Methods:We selected the reversible pulpitis of 18 cases and the symptomatic irreversible pulpitis of 22 cases caused by caries, a total of 40 teeth. They both received vital pulp therapy and had a followed-up of 3 months. We compared 3 months of short-term curative effect on the two diseases. Results:The successful rate of the reversible pulpitis group was 77.8%. The successful rate of symptomatic irreversible pulpitis group was 90.9%. Three-months of short-term curative effects between reversible pulpitis and symptomatic irreversible pulpitis group were not significantly different（P>0．05）. Conclusion: Symptomatic irreversible pulpitis could be achieved vital pulp therapy and its 3-months of short-term curative effect does not show the difference from reversible pulpitis.
