Among diabetic patients, significantly higher s-IgA levels were concomitant with xerostomia and denture stomatitis. 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 ( 0.050). s-IgA levels were significantly higher in subjects with oral candidiasis ( 0.050). Among diabetic patients, significantly higher s-IgA levels were concomitant with xerostomia and denture stomatitis (0.050). There were no significant differences between s-IgA concentrations and other oral or dental manifestations in either group. 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 (24S)-24,25-Dihydroxyvitamin D3 patients in (24S)-24,25-Dihydroxyvitamin D3 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 Tagln diabetes compared to those with controlled diabetes. and delayed wound healing.1,2 Immunoglobulin A (IgA) and immunoglobulin G (24S)-24,25-Dihydroxyvitamin D3 affect oral cavity microorganisms in the saliva, gingival sulcular fluid and plasma. 3 These antibodies prevent bacterial metabolism and adhesion of microorganisms to the oral tissue.3 Although there are many non-specific defensive elements in the saliva, such as lactoferrin and lysozymes, salivary secretory IgA (s-IgA) is the foremost protective mechanism against bacterial colonisation of the oral mucous membranes. As s-IgA plays an important role in protecting against these pathogens, the antibody might also protect against periodontal diseases.4 Changes in salivary IgA concentrations in diabetic patients could have an effect on their oral health. Several studies have sought to determine salivary flow rates and components that can affect the progression, symptoms and varieties of oral changes in diabetic patients.1,2,5 Overall, determining the salivary components of diabetic patients can be useful in detecting and managing their oral manifestations.5 Previous research has assessed s-IgA levels and oral conditions among diabetic patients. A Brazilian study reported that diabetic patients with lower s-IgA levels had more severe and frequent periodontal disease.4 However, two Iranian studies yielded different results: Mohiti-Ardekani 0.050). There was no significant difference in s-IgA levels between genders or with age. However, there was a significant increase in s-IgA levels among patients with uncontrolled T2DM compared to those with controlled disease ( 0.050). Both the DMFT and PDI indices showed significant increases among the diabetic patients in comparison with the control group ( 0.050). Between the two groups, s-IgA levels were significantly higher among subjects with a higher PDI index. Correlations between s-IgA levels and other variables are shown in Table 1. Table 1: Correlation between salivary secretory immunoglobulin A concentrations and other variables among control and diabetic subjects in Kerman, Iran (N = 260) value)= 0.050). Diabetic patients also suffered from denture stomatitis more frequently than control subjects with significantly higher s-IgA levels (0.050). Table 2: Comparison between salivary secretory immunoglobulin A levels and oral and dental manifestations among control and diabetic subjects in Kerman, Iran (N = 260) valuevalueand smoking-induced (24S)-24,25-Dihydroxyvitamin D3 oral diseases.14,17C21 Immune suppression or disturbances have been observed in diabetic patients;2 it is possible that T2DM affects the secretion of IgA in the saliva and, consequently, the defence reaction of the mucosa. In the present study, s-IgA levels in diabetic patients were not significantly higher in comparison with non-diabetic individuals. This result is similar to those seen in previous studies.5C7,9,22 In contrast, Mohiti-Ardekani was found. This correlates with previous research by Divya in comparison with normal individuals.21 In the present study, a significant increase in s-IgA levels was found in diabetic patients with denture stomatitis. A study by Papova em et al /em . also showed that s-IgA levels in patients with denture stomatitis were significantly higher in comparison to a control group.29 The results of the current study differed from those observed in a study by Wilson em et al /em ., who found that that s-IgA levels were significantly reduced denture wearers with denture stomatitis compared to healthful topics.30 Changes in the function and the different parts of saliva due to different conditions (24S)-24,25-Dihydroxyvitamin D3 among diabetics (e.g. dental care caries, periodontitis, burning up mouth area and sensory complications) aren’t yet fully realized. Previous investigations show the efficacy from the buffering capability and cleansing aftereffect of saliva in negating a few of these adjustments.16 However, the variations in s-IgA amounts in different research could be related to different sampling.
