目的探讨热牙胶垂直加压法治疗慢性牙髓炎及根尖周炎患者的临床疗效。方法选取2013年7月至2014年7月大连市口腔医院收治的80例慢性牙髓炎、根尖周炎患者作为研究对象,根据入院顺序将其分为对照组和观察组,各40例。对照组患者采用冷牙胶侧方加压法治疗,观察组患者行热牙胶垂直加压法治疗,比较两组患者的临床疗效及根管填充效果、填充时间和临床观察指标改善情况。结果观察组患者治疗的总有效率、恰填率均明显高于对照组,差异均有统计学意义(均P<0.05);观察组患者根管填充时间为(71±16)s,明显短于对照组的(146±35)s,差异有统计学意义(P<0.05);治疗后,观察组患者的GI、SBI及PD均明显低于对照组,差异均有统计学意义(均P<0.05)。结论采用热牙胶垂直加压法治疗慢性牙髓炎、根尖周炎患者临床疗效明显,可明显缩短患者根管填充时间,恰填率较高,各项临床指标改善良好。
Objective To investigate the clinical effect of hot denture vertical pressurization on chronic pulpitis and periapical periodontitis. Methods Eighty patients with chronic pulpitis and periapical periodontitis admitted to Dalian Stomatological Hospital from July 2013 to July 2014 were enrolled in this study. They were divided into control group and observation group according to admission sequence, 40 cases in each. Patients in the control group were treated with cold teethers lateral compression. Patients in the observation group were treated with hot teethers by vertical compression. The clinical curative effect, root canal filling effect, filling time and clinical observation indicators were compared between two groups. Results The total effective rate and the correct filling rate in the observation group were significantly higher than those in the control group (all P <0.05). The filling time in the observation group was (71 ± 16) s, which was significantly shorter (146 ± 35) s in the control group, the difference was statistically significant (P <0.05). After treatment, the GI, SBI and PD in the observation group were significantly lower than those in the control group, the differences were statistically significant (P <0.05). Conclusions The treatment of chronic pulpitis by hot dentin vertical pressurization is effective. The clinical curative effect of patients with periapical periodontitis is obvious. It can shorten the time of root canal filling, and the filling rate of the root canal is higher. All the clinical indexes are improved well.
