RESUMO
Objectives: Oral and dental manifestations in diabetic patients can arise due to numerous factors, including elevated salivary secretory immunoglobulin A [s-IgA] levels. This study aimed to evaluate s-IgA concentrations in patients with type 2 diabetes mellitus [T2DM] and to investigate the association between s-IgA levels and oral and dental manifestations of T2DM
Methods: This cross-sectional descriptive study was carried out between October 2011 and September 2012 in Kerman, Iran, and included 260 subjects [128 patients with T2DM and 132 healthy controls]. Unstimulated salivary samples were collected from all subjects and s-IgA levels were determined using the immunoturbidimetric method. The oral cavities and teeth of T2DM patients were evaluated for oral and dental manifestations
Results: Both diabetic and control subjects with higher concentrations of s-IgA had significantly higher numbers of decayed, missing or filled teeth [DMFT] and periodontal index [PDI] scores [P <0.050]. s-IgA levels were significantly higher in subjects with oral candidiasis [P <0.050]. Among diabetic patients, significantly higher s-IgA levels were concomitant with xerostomia and denture stomatitis [P
Conclusion: Individuals with a greater number of DMFT, a higher PDI score and oral candidiasis had significantly higher s-IgA levels. s-IgA levels were not significantly higher among diabetic patients in comparison to the control group. However, significantly higher s-IgA levels occurred with xerostomia and denture stomatitis in diabetic patients. In addition, s-IgA was significantly higher in patients with uncontrolled diabetes compared to those with controlled diabetes
