目的探讨不同充填剂治疗乳牙根尖周炎的近远期临床疗效。方法我院诊治的120颗患尖周炎的乳牙,随机将其分为A(使用干髓糊剂进行充填)、B(使用氢氧化钙碘仿糊剂进行充填)、C(使用抗生素糊剂进行根管充填)三个治疗组,治疗3个月、6个月、1年后,比较各组患牙的治疗成功率。结果于治疗3个月、6个月和1年,与A组相比,B组和C组的成功率都明显升高,P<0.05,差异具有统计学意义;与B组相比,C组的成功率没有明显差异,P>0.05。近期失败的主要临床表现为存在不同程度的咬合痛、叩击痛,窦道没有消失;远期的主要临床表现为牙齿折断、充填物脱落、继发龋齿。结论氢氧化钙碘仿糊剂和抗生素糊剂根管充填是目前治疗乳牙根尖周炎的相对比较有效方法,值得临床推广应用。
Objective To investigate the short-term and long-term clinical efficacy of different filling agents in the treatment of apical periodontitis of deciduous teeth. Methods A total of 120 cases of periapical primary deciduous teeth diagnosed in our hospital were randomly divided into A (filling with dry pulp paste), B (filling with calcium hydroxide iodoform paste), C (using antibiotic paste Root canal filling) three treatment groups, the treatment of 3 months, 6 months, 1 year after the treatment of teeth in each group compared the success rate. The results in the treatment of 3 months, 6 months and 1 year, compared with the A group, B and C group were significantly higher success rate, P <0.05, the difference was statistically significant; compared with the B group, C No significant difference in the success rate of the group, P> 0.05. Recent clinical manifestations of failure for the presence of varying degrees of bite pain, percussion pain, the sinus did not disappear; long-term clinical manifestations of broken teeth, fillings fall off, secondary to dental caries. Conclusion Calcium hydroxide iodoform paste and antibiotic paste root canal filling is the relatively effective method for the treatment of apical periodontitis of deciduous teeth, which is worthy of clinical application.
