摘　　要：目的为研究显影塑化剂在牙髓塑化治疗的显影效果。方法对采用碘化钠显影塑化剂塑化后的６５颗离体牙，进行Ｘ线片和体视镜下评定。结果显示离体牙中显影对比度优良率为８６．１１％，显影深度优良率为９５．３７％。结论显影塑化剂的显影深度可真实反映其在根管内充盈的实际深度。Objective To study the possibility of using radiopaque resinifying agent in resinification of the tooth. Methods 65 teeth resinified with radiopaque resinifying agent in vitro were evaluated on X ray films and through stereomicroscope.Results 86.11% of the root canals on X ray films was with good contrast, 95.37% of them was with enough radiopaque length. Conclusion The radiopaque length could really indicate the filling length of the radiopaque resinifying agent in the root canals.
