龋患者唾液流率和无机成份测定

The test of the inorganic substances in saliva flow rate in patieats w ith caries

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。

Thirty-three persons aged 18-33 years with crown caries or without caries and fifty-two persons aged 47-74 years with crown and root caries or w ithout caries were selected in this test in order to analyse the differenecs of the Orae Health Indexes Salivary flow rates and—mateviats batween persons with caries and without caries. The results showed fhat he Oral Health lndexes ih patlets with caries weve hegher than in persons without Caries canwng the young populatin. Also the differeaces of the calcium in saliua between patients with root caries and person without caries were significant.
