Introduction: Diabetes mellitus has extensive oral consequences which could be referred to changes of saliva properties. The purpose of this study was to compare the pH of un-stimulated whole saliva between diabetic patients that referred to diabetes center of Yazd Shahid Sadoughi university and non- diabetic persons. Methods: In this Case- control study, the population consisted of 60 persons in 2 groups: Thirty diabetic patients(type 2) and 30 non-diabetic persons. Two patients of case group were excluded from study due to inconsistency of their salivary pH and pH paper. Sampling from saliva was performed after 2 hours of abstinence from eating and smoking. Then pH of samples was measured by the pH paper that was scored from 5.5 to 8. After that blood sample was taken for measuring FBS. Data from 2 groups was analyzed using t-test, Mann-Whitney test and Spearman correlation by SPSS software(ver. 12). Results: Mean pH in case and control groups was 6.11 ±0.57 and 6.66±0.64, respectively. The results showed that pH of un-stimulated whole saliva in diabetic patients was significantly lower than control group(P=0.001). Conclusion: pH of un-stimulated whole saliva in diabetic patients was lower than non-diabetic persons and pH of un-stimulated whole saliva had a reverse relationship with FBS(P=0.031).
