Objectives:
Thy-1 (CD90) is a glycosylphosphatidyl-anchored protein belonging to the immunoglobulin family and is known to control mesenchymal stromal cells differentiation into osteoblasts or adipocytes. The study aimed to investigate the salivary levels of Thy-1 in health, periodontitis, obesity, and any potential association.
Materials And Methods:
Seventy-one participants were divided into four groups: healthy (H), subjects with periodontitis (P), obese individuals (O), and obese individuals having periodontitis (PO). Unstimulated whole saliva was collected from participants who were evaluated for periodontal parameters. The levels of Thy-1 were measured with a commercially available ELISA kit. The data were statistically analyzed.
Results:
A significant difference in salivary Thy-1 levels among different groups was observed. Periodontitis patients had the maximum, and obese individuals had the minimum Thy-1 levels. Significant differences between H and P, H and PO, P and O, and O and PO were observed. Overall correlations between Thy-1 and periodontal parameters and a positive correlation with pocket depth in group PO were noted.
Conclusion:
Thy-1 could be detected in the saliva of all study participants. It is implied that a local inflammatory condition like periodontitis elevates the salivary levels of Thy-1 with, and without obesity.
