摘　　要：目的分析并比较塑化液、墨水、指甲油和热牙胶4种髓腔灌注材料在透明牙制作中的使用效果。方法收集新鲜拔除的前磨牙20颗,常规处理后随机分为4组,分别用塑化液、墨水、指甲油和热牙胶4种材料进行髓腔灌注,比较各组根管形态显示的清晰度及染色效果的持久性。结果4种材料注入后,均能清楚显示根管形态,但塑化液髓腔灌注材料与脱钙牙体组织之间颜色对比度好,无褪色现象;碳素墨水有染色范围扩大的现象;指甲油在固定液中颜色不持久,易褪色;热牙胶与脱钙牙体组织之间颜色对比度欠佳。结论制作透明牙的4种髓腔灌注材料中,塑化液的灌注效果要优于墨水、指甲油及热牙胶。Objective To analyze and compare four kinds of materials including petrochemistry liquid, ink, nail polish and the thermoplasticized gutta-percha in the usage for transparent tooth creation. Methods Twenty freshly extracted young pre - molars randomly divided into four groups and the four kinds of materials were used respectively for root canal filling. Results Four kinds of materials can all show root canal routes clearly after infusing. The petrochemistry liquid type material exhibited obvious contrast with the remaining teeth body and fading is not prominent; The ink has illicit intercourse and infused into the remaining teeth body quickly; The color of nail polish can not hold for a long time and faded out most quickly in four, while thermoplasticized gutta-percha showed unclear contrast with remaining teeth body. Conclusion The filling effect of petroohemistry liquid is better than ink, nail polish and thermoplasticized gutta-percha.
