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，牙齿疾病（EX，龋齿）被视为口腔感染和多氏疾病。因此，要评估单个的致癌菌群，致癌性和生活习惯对于全面的口腔疾病护理很重要，这是很正常的。我们有一些固定的龋齿风险测试系统（例如牙齿和CRT）来估计唾液变异体链球菌，乳酸杆菌，这些系统在临床上用于检测潜在的龋齿风险患者。这项研究的目的是比较系统的结果变量的可靠性水平，并间接评估系统的有效性，从CHX口冲洗的影响方面。从临床观点，牙道和CRT系统的可靠性在临床上是可接受的，这两种测试似乎都是有用的方法，可以筛选其Caries风险。但是，它们的DMFT值与本研究中使用的龋齿风险测试结果相关。这可能是合理的，因为DMFT值代表了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，它们在横截面时火焰中相关的数据可能不足以描绘系统的实际效用。在不久的将来，可能需要更富裕的前瞻性队列研究。另一方面，CHX口冲洗减少了唾液中链球菌的链球菌数量，而乳酸乳杆菌的数量没有对CHX口冲洗的反应。
