目的对比MTA和Vitapex根尖诱导成形术治疗感染型畸形中央尖的成功率。方法 98例感染型畸形中央尖患者(122颗前磨牙),依据根尖诱导药物的不同分为研究组49例(65牙)与对照组49例(57牙)。对照组予以Vitapex根尖诱导治疗,研究组予以MTA根尖诱导治疗。比较两组患者感染治疗相关指标、诱导周期以及诱导疗效。结果研究组牙周病变消失时间、咀嚼功能恢复时间、红肿消退时间均短于对照组,就诊次数少于对照组,差异具有统计学意义(P<0.05)。研究组诱导周期情况显著优于对照组,差异具有统计学意义(P<0.05)。研究组组诱导成功率为95.38%,显著高于对照组的80.70%,差异具有统计学意义(P<0.05)。结论予以感染型畸形中央尖患者MTA根尖诱导治疗可缩短感染治疗时间,并提高诱导成功率,值得推广。
Objective To compare the success rates of MTA and Vitapex apical inductive angioplasty in the treatment of infective deformity. Methods A total of 98 patients with central malformation (122 premolar) were divided into study group (49 teeth) and control group (49 teeth) according to the apical induction drug. The control group was given Vitapex apical induction therapy, and the study group was given MTA apical induction therapy. The infection-related indicators, induction period and induction effect were compared between the two groups. Results The duration of periodontal lesions disappear, recovery time of chewing function, redness and remission time were shorter in the study group than in the control group, the number of visits was less than the control group, the difference was statistically significant (P <0.05). The induction period of the study group was significantly better than the control group, the difference was statistically significant (P <0.05). The success rate of induction in the study group was 95.38%, which was significantly higher than that in the control group (80.70%), the difference was statistically significant (P <0.05). Conclusion It is worth to popularize that the MTA apical induction therapy can reduce the treatment time of infection and improve the success rate of induction.
