项目摘要

Nowadays, dental diseases (ex, dental caries) are regarded as oral infection and pluricausal diseases. Thus, it is very normal that to evaluate individual cariogenic flora, cariogenic resistance and living habits is thought to be important for the comprehensive oral disease cares. We have some commertially available caries risk test systems (such as Dentocult and CRT) for estimating salivary mutans streptococci, lactobacillus and those systems are clinically used for detection of potential caries risk patients. The aim of this study is to compare the reliability levels of the outcome variables of the systems and indirectly asses the validity of the systems in terms of the effect of CHX mouth rinse.From a clinical point of view, the reliability of Dentocult and CRT systems was clinically acceptable and both tests seemed useful method for screening their caries risk. However, their DMFT values were poorly correlated to their results of the caries risk tests utilied in this study. This might be reasonable because the DMFT value represents past history of the patient's oral environment, not the on-going pathological process. So their correlated data in a cross-sectional time flame might not be enough to depict the real utility of the systems. More regorous prospective cohort study might be needed in the near future. On the other hand, CHX mouth rinse reduced the number of mutans streptococcii in saliva, while the number of lactobacilli did not respond to the CHX mouth rinse.

如今，牙科疾病（例如龋齿）被视为口腔感染和多发病。因此，评估个体的致龋菌群、致龋抵抗力和生活习惯对于口腔疾病的综合护理具有重要意义。我们有一些市售的龋齿风险测试系统（例如 Dentocult 和 CRT），用于估计唾液中的变形链球菌、乳酸菌，这些系统在临床上用于检测潜在龋齿风险患者。本研究的目的是比较系统结果变量的可靠性水平，并间接评估系统在 CHX 漱口水效果方面的有效性。从临床角度来看，Dentocult 和 CRT 系统的可靠性临床上可以接受，这两种测试似乎都是筛查龋齿风险的有用方法。然而，他们的 DMFT 值与本研究中使用的龋齿风险测试结果相关性较差。这可能是合理的，因为 DMFT 值代表患者口腔环境的过去历史，而不是正在进行的病理过程。因此，它们在横截面时间火焰中的相关数据可能不足以描述系统的真实效用。在不久的将来可能需要进行更严格的前瞻性队列研究。另一方面，CHX漱口水减少了唾液中变形链球菌的数量，而乳酸杆菌的数量对CHX漱口水没有反应。
