活髓切断术治疗乳牙深龋的疗效评价

目的 评价活髓切断术治疗深龋乳磨牙的疗效。方法 随机选择32例年龄在3－8年儿童的深龋乳磨牙45颗行活髓切断术，术后跟踪随访1／2a、1a、2a。结果 术后1a随访45接受治疗的深龋乳磨牙。临床及X线片成功率均为100％。术后2a随访42颗牙，失访3颗牙，临床成功率为95％，X线片成功率为88％。失败原因为内吸收、充填体折断脱落未及时就诊而引起牙髓炎症。结论 活髓切断术用于乳牙深龋确实为一种可靠、恰当、有效的治疗方法。术后应注意定期拍摄X线片复查，出现问题及时处理。

Clinical Evaluation of Pulpotomy in the Treatment of Deciduous Teeth with Deep Dentine Caries

Objective To study the curative effect of pulpotomy in the treatment of deciduous teeth with deep caries.Methods 45 deciduous molars with deep caries from 3-8 years old children were selected at random. Pulpotomy was performed on these treated teeth. Clinical examination and X ray films for the treated teeth were taken to follow up all the teeth at 6 months, one year and two years respectively after treatment.Results At one year after treatment, 45 cases were followed up, the rate of success in clinical examination and in X ray photographs both were 100%. While at two years after treatment, 42 cases were followed up and 3 cases were lost, the rate of success in clinical examination was 95% and the rate of success in X ray photographs was 88%. The reasons of the failure were internal absorption and pulpitis followed by fracture and exfoliation of the obturators in the treated teeth.Conclusion Pulpotomy in deciduous teeth with deep caries was a reliable and effective method. It is necessary to follow up the treated teeth by X ray at regular intervals after treatment.
