目的探讨干髓术与根管治疗术治疗老年人磨牙牙髓病变的临床疗效。方法依照就诊顺序将128例老年磨牙牙髓病变患者随机分为干髓术组和根管治疗组各64例,分别用干髓术、根管治疗术治疗,记录手术所需时间,术后随访观察近远期疗效。结果干髓术组术后第1、2、3年手术总有效率分别为95.3%、87.5%和82.8%,均低于同期根管治疗组总有效率(分别为96.9%、92.2%和90.6%),但差异无统计学意义(P>0.05);干髓术组平均操作时间85 min,明显短于根管治疗组的150 min(P<0.01)。结论老年人磨牙牙髓病变的临床治疗应视牙髓病变的严重程度和干髓术、根管治疗术的适应证范畴来选择治疗方式。
Objective To investigate the clinical efficacy of stemmedomy and root canal therapy for the treatment of dental pulp injury in the elderly. Methods According to the order of treatment, 128 elderly patients with dental pulp lesions were randomly divided into two groups: the medullary surgery group and the root canal therapy group, with 64 cases in each group. The patients were treated with dry pulp and root canal respectively. The time required for operation and follow-up were recorded Observation of short-term efficacy. Results The total effective rates of the first, second and third years after operation in the dry-marrow group were 95.3%, 87.5% and 82.8%, respectively, which were lower than those in the root canal-treated group (96.9%, 92.2% and 90.6 %), But the difference was not statistically significant (P> 0.05). The mean operation time of the medullary surgery group was 85 min, which was significantly shorter than that of the root canal therapy group for 150 min (P <0.01). Conclusion The clinical treatment of dental pulp disease in the elderly should be considered the severity of dental pulp disease and dry pulp surgery, root canal treatment of indications to choose the treatment.
