本文以３３名１８－３３岁青年人（无龋组、冠龋组）和５２名４７－７４岁中、老年人（无龋组、冠龋组、根龋组）为检测对象，分析无龋者和龋患者（冠龋、根龋）之间口腔卫生、唾液流率及无机成分含量的差别。结果表明，无龋者唾液率高于龋患者（冠龋、根龋），但无显著性差异；龋患者ＯＨＩｓ高于无龋者，但仅在青年人中有非常显著性差异。中、老年人根龋组的唾液钙含量显著高于无龋组，除此之外，龋患者唾液无机成分含量并不低于无龋者，可能与脱矿有关。
In this study, 33 young people aged 18-33 (caries-free group, carious crown caries group) and 52 middle-aged and elderly people aged 47-74 years (caries-free group, carious caries group, root caries group) And dental caries (caries, root caries) between oral hygiene, saliva flow rate and inorganic content of the difference. The results showed that caries-free saliva rate was higher than caries (caries, root caries), but no significant difference; caries patients OHIs higher than those without caries, but only in young people have very significant differences. The calcium content of saliva in root caries group was significantly higher than that in caries-free group. In addition, the content of saliva in caries patients was not lower than those without caries, which may be related to demineralization.
