ABSTRACT
The objective of the study is to compare xerostomia condition, hyposalivation and some oral factors between diabetic and non-diabetic subjects. Samples of the study were 42 diabetic patients who were treated diabetes in Bangkruai hospital and other 46 non-diabetic patients who visited out-patient department of the same hospital during February and March 2008. Data was collected by using questionnaire on general history and diabetic history, and xerostomia assessment form. Salivary flow rate was investigated by spitting method. Oral condition was examined as directed by WHO. Data was analyzed by Chi-square, Independent t-test, Mann-Whitney U test and Regression statistics. It is found that there is no statistical difference of salivary flow rate, caries score, and xerostomia condition between diabetic and non-diabetic group. Contrarily, hyposalivary condition and number of teeth remaining in the mouth are related to diabetic condition statistically.Key words: xerostomia, hyposalivation, salivary flow rate, diabetes mellitus
