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。
The purpose of this study was to investigate the effect of developing plasticizers on the development of dental pulp plasticization. Methods Sixty-five isolated teeth plasticized with sodium iodide developing plasticizer were evaluated by X-ray and endoscopy. The results showed that the excellent contrast rate of developing teeth was 86.11% and the good developing depth was 95.37%. Conclusions The depth of development of the developing plasticizer can truly reflect its actual depth of filling in the root canal.
