| 摘 要： | 目的]通过检测镍铬合金熔附烤瓷冠修复后唾液中镍铬离子的浓度,探讨镍铬合金内冠临床应用的安全性。方法]选取50名身体健康,口腔内无修复体及金属充填体者作为正常对照组;90名行镍铬合金烤瓷冠修复的患者作为病例组。采用吐唾法收集对照组及病例组晨起无刺激唾液5ml,分别将对照组与病例组以pH试纸分为酸性、中性、碱性3组。利用电感耦合等离子体质谱仪(ICP-MS)测定唾液中镍铬离子浓度。采用SPSS13.0统计软件对检测结果进行统计学分析。结果]唾液镍含量:病例组与对照组比较差异无统计学意义(P﹥0.05);唾液铬含量:病例组与对照组比较差异无统计学意义(P﹥0.05);镍离子在酸性、中性、碱性唾液中差异有统计学意义(P﹤0.05),在酸性唾液中,对照组与病例组差异有统计学意义(P﹤0.05),在中性与碱性唾液中,对照组与病例组差异无统计学意义(P﹥0.05);铬离子在酸性、中性、碱性唾液中差异有统计学意义(P﹤0.05),在酸性唾液中,对照组与病例组差异有统计学意义(P﹤0.05),在中性与碱性唾液中,对照组与病例组差异无统计学意义(P﹥0.05)。结论]唾液中镍、铬离子的浓度与是否行镍铬合金烤瓷冠修复没有相关性,唾液中镍、铬离子的浓度受唾液pH值影响。
