摘要
目的 观察氢氧化钙甘油糊剂用于根管封药的临床疗效。方法 选择 2 44例慢性根尖周炎病例 ,随机分观察组 (氢氧化钙甘油糊剂组 ) 12 4例、对照组 (甲醛甲酚组 ) 12 0例 ,观察封药一周后的临床疗效和细菌培养结果。结果 两组的临床效果有显著差异 (P <0 .0 1)。Ca(OH) 2 组 67.7%一次封药后即可行根管充填 ,FC组为 40 % ,Ca(OH) 2 组治疗期间未产生疼痛 ,FC组则有 8.3 %产生疼痛 ,平均封药次数Ca(OH) 2 组 1.3 8次 ,FC组1.76次 ,细菌培养结果与此呈正相关。结论 氢氧化钙甘油糊剂在杀灭微生物。
Objective To evaluate and compare the efficacy of calciun hydroxide or formocresol as an intracanal medicament in root canal therapy of periapical periodontitis teeth.Methods A randomized study of intracanal placement of calcium hydroxide paste as a therapy for teeth with periapical periodontitis was performed. 244 teeth with periapical periodontitis were randomly allocated to either the formocresol group (F) or the calcium hydroxide group (C). After the root canals were hand instrumented ,they were given intracanal placement of calcium hydroxide glycerin paste by using sprial filler or formocresol by using absorbent paper points,replaced the intracanal medicament or filled the root canal if signs and symptoms were disapeared after a 1 week period.The effects and microbiologic test performance were investigated. Results Statistically significant differences between calcium hydroxide and formocresol was found.Sixty seven point seven percent (84/124) of teeth treated with calcium hydroxide and forty percent (48/120) treated with formocresol were obturated at the second visit(chi squaretest P < 0.01 ).Incidence of post operative pain after using formocresol was eight point three percent (10/120) ,post operative pain were absent in group(C)( P < 0.05 ). A significant correlation between microbiologic test performance and clinical efficacy was observed.Conclusion This investigation confirms that calcium hydroxide paste was superior to formocresol as an intracanal medicament in root canal therapy of periapical periodontitis teeth.
