OBJECTIVETo observe the general status, subjective syndromes, objective signs and salivary secretion of xerostomia patients for studying their correlations.

METHODSEighty patients' clinical data were collected and classified according to certain standards. The salivary secretion including the unstimulated whole saliva (UWS) and stimulated whole saliva (SWS) in five minutes was measured by spit method.

RESULTSDecreased UWS was the main presentation of xerostomia which accouted for seventy five percents. Significantly statistical correlation were found between the decreased UWS and the dry mouth signs but not the age, sex and the accompany syndromes.

CONCLUSIONXerostomia has a high prevalence in middle-aged women with a long course and obvious regularity. The decreased UWS is the main presentation which was not caused by physiological changes of salivary glands and has no correlation with many clinical manifestations.
