目的探讨隐裂性牙髓炎采取不同根管治疗术的疗效。方法选取于2013年8月—2014年8月期间本院接收的隐裂性牙髓炎患者80例,共有患牙102颗,根据治疗方案的不同将入选患者分为对照组与观察组,两组分别采取传统多次根管治疗和一次性根管治疗,观察两组治疗成功率、复诊疼痛情况及根备前及根充前细菌菌落情况。计量资料采用t检验,计数资料采用χ2检验,P<0.05为差异有统计学意义。结果观察组、对照组治疗成功率分别为92.3%、88.0%,观察组治疗成功率稍高于对照组,对比差异无统计学意义(P>0.05)。两组治疗后复诊疼痛患牙均较少,分别为11.5%、10.0%,对比差异无统计学意义(P>0.05)。根充前,观察组兼性厌氧菌、厌氧菌菌落计数明显少于对照组[(6.6±1.8)、(11.8±2.1)、(10.5±1.9)、(70.5±12.3)cfu/ml],对比差异均有统计学意义(均P<0.05)。结论隐裂性牙髓炎采取一次性根管治疗,只要严格把握适应证,即可取得与传统多次根管治疗术一样的疗效,值得推广。
Objective To investigate the curative effect of different root canal therapies in patients with cryptogenic pulpitis. Methods Eighty patients with cryptogenic pulpitis received in our hospital from August 2013 to August 2014 were enrolled. A total of 102 teeth were included. According to the different treatment options, the patients were divided into control group and observation group. The patients were treated by conventional root canal therapy and multiple root canal therapy respectively. The success rate of treatment, the pain of referral and the bacterial colonies before rooting and rooting were observed. Measurement data using t test, count data using χ2 test, P <0.05 for the difference was statistically significant. Results The success rates of observation group and control group were 92.3% and 88.0%, respectively. The success rate of treatment in observation group was slightly higher than that in control group (P> 0.05). There were less teeth in the two groups after treatment, which were respectively 11.5% and 10.0%. There was no significant difference between the two groups (P> 0.05). Before root filling, the number of anaerobic bacteria in the observation group was significantly less than that in the control group [(6.6 ± 1.8), (11.8 ± 2.1), (10.5 ± 1.9), (70.5 ± 12.3) cfu / ml] , The differences were statistically significant (P <0.05). Conclusions A one-time root canal treatment of cryptogenic pulpitis is taken. As long as indications are strictly followed, the same curative effect as traditional multiple root canal therapies can be obtained and is worth promoting.
