摘要: 目的:初步探讨4~5岁儿童唾液、菌斑液中碳酸酐酶Ⅵ(CA-Ⅵ)含量与龋病的关系。方法:以无龋组、低龋组、高龋组儿童各33名为研究对象,采用ELISA法检测唾液、菌斑液中CA-Ⅵ含量,H+-ISFET测定菌斑液pH值,并进行统计学分析。结果:唾液CA-Ⅵ含量:无龋组>低龋组>高龋组,各组间有统计学差异(P<0.05);菌斑液CA-Ⅵ含量:无龋组>低龋组>高龋组,各组间有统计学差异(P<0.05);唾液、菌斑液CA-Ⅵ含量和菌斑液pH值呈线性正相关(P<0.001)。结论:随着龋病严重程度的增加,唾液、菌斑液CA-Ⅵ水平呈下降趋势。CA-Ⅵ可上调牙表面菌斑pH值,对保护牙齿、抵抗龋病有重要作用。

Abstract: Objective: To investigate the relationship between dental caries and CA-Ⅵ levels in saliva and dental plaque fluid in children aged 4-5 years. Methods: Thirty-three children were randomly selected for each group: caries-free group, low caries group, and high caries group. The levels of CA-Ⅵ in dental plaque and saliva were examined by ELISA. The pH values of dental plaque fluid were detected by H+-ISFET. The results were statistically analyzed. Results: The CA-Ⅵ levels in saliva were statistically different among three groups: caries-free group>low caries group>high caries group (P<0.05). The CA-Ⅵ levels in dental plaque fluid were significantly different among three groups: caries-free group>low caries group>high caries group (P<0.05). Pearson's correlation analysis showed CA-Ⅵ levels in saliva and dental plaque fluid were positively related to pH values of dental plaque fluid (P<0.001). Conclusion: With the increase of caries severity, the levels of CA-Ⅵ in saliva and dental plaque fluid decreased. CA-Ⅵ might increase the pH values of plaque on the dental surface, and play an important role in tooth protection and caries resistance.
