目的:研究不同方法去除直根管和弯曲根管内氢氧化钙封药的差异。方法:建立直根管、弯曲根管的体外标准化模型,用根管锉、超声冲洗器械、EndoActivator配合注射器冲洗去除根管内氢氧化钙封药,随后打开模型,体视显微镜下拍照,软件测量,计算氢氧化钙残余量并进行统计分析。结果:不同方法去除氢氧化钙能力:直根管中K锉≈EndoActivator≈P5>直接冲洗;弯曲根管中EndoActivator≈预弯P5>P5>预弯K锉>K锉>直接冲洗。弯曲根管与直根管之间,K锉组、P5组、EndoActivaor组之间均有显著差异(P<0.05)。结论:3种方法均不能完全去除根管内氢氧化钙,EndoActivaor是去除根管内氢氧化钙的较好方法。
目的:研究不同方法去除直根管和彎麯根管內氫氧化鈣封藥的差異。方法:建立直根管、彎麯根管的體外標準化模型,用根管銼、超聲遲洗器械、EndoActivator配閤註射器遲洗去除根管內氫氧化鈣封藥,隨後打開模型,體視顯微鏡下拍照,軟件測量,計算氫氧化鈣殘餘量併進行統計分析。結果:不同方法去除氫氧化鈣能力:直根管中K銼≈EndoActivator≈P5>直接遲洗;彎麯根管中EndoActivator≈預彎P5>P5>預彎K銼>K銼>直接遲洗。彎麯根管與直根管之間,K銼組、P5組、EndoActivaor組之間均有顯著差異(P<0.05)。結論:3種方法均不能完全去除根管內氫氧化鈣,EndoActivaor是去除根管內氫氧化鈣的較好方法。

AIM:To compare the efficacy of different techniques in the removal of calcium hydroxide〔Ca (OH)2〕in straight and curved root canals.METHODS:The straight and curved root canal models were established using extracted tooth roots.K file,ultrasonic and EndoActivator were respectively used for the removal of Ca(OH)2 (n=10).The residual Ca(OH)2 was observed by stereomicroscope,the percentage of residual Ca(OH)2 was analyzed and calculated using the photographs taken by camera attached to stereomicroscope.RESULTS:In straight root canal models,the Ca(OH)2 removal efficacy was in the following order:EndoActivator≈P5 ≈asmall K file >irrigation;while in curved root canal models,EndoActivator≈precurved P5 >P >pre-curved small K file>small K file>irriga-tion.The percentage of residual Ca(OH)2 in the curved canals was higher than that in straight canals (P<0.05 ). CONCLUSION:EndoActivaor is the most effective for Ca(OH)2 removal.But none of methods used can completely remove Ca(OH)2 in root canal.
