本研究旨在探讨口腔干燥的症状与不同唾液变量的关系，并将口腔干燥的主观主诉与唾液流率联系起来。312名未服药的健康个体，属于三个年龄组（6-11岁、12-17岁和18-40岁），临床检查口腔干燥的迹象。收集静息和刺激唾液，测定流速、pH值和缓冲能力。采用问卷调查法了解口干主观感觉情况。干唇和干黏膜分别占37.5%和3.2%。抱怨口腔干燥的受试者比例（19%）显示刺激的唾液流率明显低于没有抱怨的受试者。干唇与静息流速显著相关，而pH和缓冲能力与干唇无显著相关。干粘膜与上述参数均无相关性。在抱怨口干的受试者中，受刺激的唾液流量减少的发现具有重要的临床意义，因为这种减少预计会反映在各种唾液功能的损害上。
This study aimed to investigate the signs of oral dryness in relation to different salivary variables and to correlate subjective complaints of oral dryness with salivary flow rate. 312 unmedicated healthy individuals belonging to three age groups, (6–11, 12–17, and 18–40 years) were examined clinically for signs of oral dryness. Resting and stimulated saliva were collected to determine flow rate, pH and buffering capacity. A questionnaire was used to obtain information on subjective sensation of dry mouth. Dry lip and dry mucosa were present in 37.5% and 3.2% of the sample respectively. The proportion of subjects who complained of oral dryness (19%) showed a stimulated salivary flow rate significantly lower than non complainers. Dry lip was significantly related to low resting flow rate but pH and buffering capacity did not show any significant relation to dry lip. Dry mucosa was not related to any of the above mentioned parameters. The finding that the stimulated salivary flow rate was reduced in subjects complaining of dry mouth is of great clinical relevance, since the reduction is expected to be reflected in compromising various salivary functions.
