摘要
选择急性牙髓炎患者130例,患牙150颗,松动不超过Ⅰ度,按随机数字表法分为氢氧化钙组和樟脑酚组,每组75颗患牙。氢氧化钙组根管内封入氢氧化钙糊剂,樟脑酚组将丁香油置入根管内开放,治疗2d后复诊,置入樟脑酚棉捻。氢氧化钙组治疗2周后复诊,去除氢氧化钙糊剂,清理根管后用Vitapex糊剂加牙胶尖侧压法进行常规根管充填。樟脑酚组治疗1周后复诊,取出根管内棉捻,丁香油氧化锌根充糊剂加牙胶尖侧压法进行常规根管充填。结果表明,氢氧化钙组复诊次数低于樟脑酚组。氢氧化钙组治疗后0.5,1,3年治疗成功率分别为94.6%(71/75),90.6%(68/75),89.3%(67/75)。樟脑酚组治疗后0.5,1,3年治疗成功率分别为93.3%(70/75),92.0%(69/75),89.3%(67/75)。经统计学检验,两组间差异无显著性意义(P>0.05)。长期随访可见氢氧化钙充填材料治疗急性牙髓炎与传统治疗方法疗效相当,但操作比传统药物简单,复诊次数减少。
A total of 130 patients with acute pulpitis, involving 150 teeth loosening less than I degree, were selected and＇divided into two groups, each group containing 75 teeth. In A group, calcium hydroxide paste was enclosed into canal and removed two weeks later, then using lateral pressure method the Vitapex paste and gutta percha point were used for the root canal filling of returned patients; In B group, the canal was opened with clove oil, twisted with phenocamphor, and removed one week later. Then clove oil zinc oxide paste and gutta percha point were used for the root canal filling. The result of this experiment showed that the time of return visit in A group was lower than that in B group. Half a year, 1 year and 3 years postoperation, the successful rate of A group were 94.6% （71/75）, 90.6% （68/75）, 89.3% （67/75）, respectively, while those of B group were 93.3% （70/75）, 92.0% （69/75）, 89.3% （67/75）. There was no statistically significant difference between the two groups （P 〉 0.05）. During a long-term follow-up, calcium hydroxide paste as filling materials has the identical effect with the common therapy in the treatment of acute pulpitis, and it is easy to operate and reduces the returning time.
