Extracted teeth, root-filled by single cone and lateral condensation techniques, using friction fitted and solvent (chloroform and eucalyptol) dip-fitted primary gutta-percha cones, were compared with respect to apical sealing as measured by length of dye penetration and frequency of no dye penetration. Overall, the single cone techniques were significantly more effective than lateral condensation techniques regarding length of dye penetration. The single cone techniques were not significantly different from the lateral condensation technique which employed chloroform dip-fitted primary gutta-percha cones regarding length of dye penetration. The single cone and lateral condensation techniques which utilized chloroform dip-fitted cones ranked first and second with respect to frequency of no dye penetration.
采用摩擦配合和溶剂（氯仿和桉叶油）浸渍配合的初级牙胶尖，通过单锥法和侧向加压法进行根管充填的离体牙，就染料渗透长度和无染料渗透频率所测量的根尖封闭情况进行了比较。总体而言，就染料渗透长度而言，单锥法比侧向加压法显著更有效。在染料渗透长度方面，单锥法与采用氯仿浸渍配合初级牙胶尖的侧向加压法没有显著差异。在无染料渗透频率方面，采用氯仿浸渍配合牙胶尖的单锥法和侧向加压法分别位居第一和第二。
