BACKGROUND
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.
METHODS
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.
RESULTS
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.
CONCLUSION
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.
背景
本研究旨在调查与不同唾液变量相关的口腔干燥迹象，并将口腔干燥的主观主诉与唾液流速相关联。
方法
对312名未用药的健康个体进行临床检查，这些个体分属三个年龄组（6 - 11岁、12 - 17岁和18 - 40岁），检查口腔干燥迹象。收集静息和刺激状态下的唾液，以测定流速、pH值和缓冲能力。使用问卷调查获取口干主观感觉的信息。
结果
样本中分别有37.5%和3.2%出现唇干和黏膜干燥。主诉口腔干燥的受试者比例（19%）显示其刺激唾液流速显著低于无主诉者。唇干与静息流速低显著相关，但pH值和缓冲能力与唇干无任何显著关系。黏膜干燥与上述任何参数均无关联。
结论
主诉口干的受试者刺激唾液流速降低这一发现具有重要临床意义，因为这种降低预计会反映在损害各种唾液功能上。
