摘要:

目的研究镍铬合金、含钛镍铬合金烤瓷冠在人体口腔环境中镍离子的析出量。方法选择50例需行单个后牙烤瓷冠修复的患者,随机分为2组,一组制作镍铬合金烤瓷冠,另一组制作含钛镍铬合金烤瓷冠。在患者戴冠前,戴冠后1周、3个月、6个月采集唾液,用ICP-MS型电感耦合等离子体质谱仪测定唾液中镍离子的质量浓度。结果戴冠后1周,2组患者唾液中镍离子的质量浓度均有增加,6个月后恢复到戴冠前的水平。经统计学检验,戴冠前及戴冠后1周、3个月、6个月,2组患者唾液中镍的质量浓度经组内比较和组间比较均无统计学差异(P>0.05)。结论镍铬合金烤瓷冠、含钛镍铬合金烤瓷冠对患者唾液中的镍含量无明显影响。

Abstract:

Objective The purpose of the study was to investigate the content of nickel(Ni) ion in patients′ saliva after wearing the porcelain -fused -to nickel -chromium(Ni -Cr) crown or the porcelain -fused -to nickel -chromium - titanium(Ni-Cr-Ti) crown. Methods 50 patients who had one molar or premolar needed repairing were selected and divided into two groups randomly. Patients in one group were fabricated with porcelain-fused-to Ni-Cr crown and the patients in the other group were fabricated with porcelain-fused-to Ni-Cr-Ti crown. Collect the patients′ saliva before wearing, 1 week, 3 months, and 6 months after wearing. The content of Ni ion in saliva was detected by inductively coupled plasma mass spectrometry(ICP-MS). Results The content of Ni ion in both groups increased at the first week, and go back after 6 months. There were no significant differences before wearing, 1 week, 3 months, and 6 months after wearing. There were no significant differences between the two groups. Conclusion Wearing the porcelain- fused-to Ni-Cr crown or the porcelain-fused-to Ni-Cr-Ti crown has no significant influence on the content of Ni ion in saliva.
