title: Levels of immunoglobulin A1 in peri-implant fluid and saliva from patients with mucositis: a preliminary study.
abstract: There are no studies evaluating the possible use of immunoglobulin A1 (IgA1) as an early marker for peri-implant inflammation. The aim of this study was to evaluate the IgA1 levels in peri-implant sulcular fluid (PISF) and saliva of partially edentulous patients as an indicator of mucositis. Twenty-seven patients were examined to determine the peri-implant status based on probing depth and bleeding on probing. Saliva and PISF around dental implants were collected and the IgA1 levels were evaluated by Elisa assay. IgA1 in saliva and PISF of these patients were compared and their correlations with clinical parameters were evaluated. Differences in IgA1 levels in saliva (821.1 ± 290.6; 779.8 ± 401.5) and PISF (26.6 ± 20.7; 25.1 ± 20.5) of healthy and mucositis groups, respectively were not observed (p>0.05). Correlation between clinical parameters and IgA1 in saliva or PISF was not observed in healthy or mucositis groups (p=0.607; p=0.826, respectively). These results suggest that IgA1 cannot be used as an immunological marker of mucositis.
