RESUMO
The present study was undertaken in order to determine the possible alterations in whole saliva and the periodontal status in patients with diabetes mellitus (DM), and was conducted on 17 patients with DM and 17 systemically and periodontally healthy subjects. When the subjects were evaluated clinically, significantly increased probing depths were noticed in the DM group when compared with the healthy subjects. In whole saliva samples, sodium, potassium, total protein, amylase, thiocyanate, and secretory IgA levels were determined in both groups. Difference between the two groups regarding the mean salivary potassium levels were found to be statistically significant since the mean salivary potassium levels in the DM and the control groups were 2.470 +/- 9.04 mmol/L and 14.30 +/- 8.88 mmol/L, respectively. The mean salivary total protein, amylase and secretory IgA levels in the DM group were 2.41 +/- 1.0 mg/mL, 124.2 +/- 79.7 U/mL and 6.86 +/- 3.50 mg/L, all being significantly higher than the control group. However, no significant differences could be shown for the salivary sodium and thiocyanate levels. Nor was there any difference between non-insulin dependent diabetes mellitus (NIDDM) and insulin-dependent diabetes mellitus (IDDM). The findings of the present study suggest that, besides the clinical examinations, the determination of the possible alterations in the composition of whole saliva might also be helpful in understanding the increased severity of periodontal disease in diabetic patients.

The effects of different stages of periodontal therapy on salivary pseudocholinesterase (PCE) activity in patients with periodontitis were determined by use of a spectrophotometric method. The mean PCE activity in whole saliva was 17.95 U/L in the pre-treatment phase, 4.67 U/L after scaling and oral hygiene instructions, and 1.93 U/L following surgical procedures. It was observed that the mean salivary PCE activity in patients with periodontitis showed a tendency to decrease in both phases of treatment, and PCE levels at the end of periodontal therapy were similar to those of healthy subjects.
