Comparison of total antioxidant capacity (TAC) of saliva in patients with type 1 diabetes compared to non-diabetics patients

Background: oxidative stress plays a crucial role in the onset and also the progression of vascular and neurological complications of diabetes. the present study was aimed to determine and compare the antioxidant capacity of saliva in patients with type 1 diabetes compared with those do not have diabetic. methods: in this case-control study, the patients aged 20-40 years referred to imam khomeini hospital in ardabil were categorized into two groups including 30 patients with type 1 diabetes as a case group and 30 non-diabetics as a control group. these two groups were compared in terms of tac levels in saliva. the tac of saliva the patients measured by 2,2′-azino-bis (3-ethylbenzothiazoline- 6-sulfonic acid) (abts) method. the analysis of data was carried out through t-test statistic using spss statistics version 24 at a significant level of p <0.05. results: based on the data achieved from the present study, the mean and standard deviation of tac of saliva in patients with type 1 diabetes was 0.380 ± 0.120 (μmol / l) and in non-diabetics was 0.306 ± 0.122 (μmol / l). the increment of tac of saliva in the case group compared to the control group was significant based on t-test (p = 0.003). conclusion: since there is a significant increment in the level of tac of saliva in patients with type 1 diabetes compared to non-diabetics, the determination of the level of tac of saliva in patients with type 1 diabetic can be used as an alternative method for early diagnosis of diabetes.
