Abstract:A number of markers show promise as sensitive measures of disease and the effectiveness of therapy. At this time, host-derived enzymes and other inflammatory mediators orginating from the gingival crevice appear to hold the greatest promise as salivary diagnostic tests for periodontal disease. Longer-term longitudinal studies, however, are required to establish the relationship between specific markers and progression of periodontal disease. Furthermore, analysis of saliva may offer a cost-effective approach t… Show more
“…Apart from inflammatory gingival fluid being the primary cause for the increase of HGF level in oral cavity, 10 other sources may also be the cause for the increase: saliva, nasal mucosal secretion, paranasal sinuses, and bronchi (in case of even subclinical inflammatory condition) as well as blood coming from small cuts within oral cavity. 32,33 We must also not forget a possible influence of the HD treatment itself on the HGF concentration in saliva. It is known that during a HD procedure the HGF concentration in the blood plasma increases considerably as a result of HGF release from proteoglycan complexes under the influence of exogenous heparin.…”

“…26 Whole saliva consists of a mixture of fluids such as water, proteins, and electrolytes secreted by the salivary glands; non-salivary components derived from the GCF; oral bacteria, including their enzymes and bacterial products; viruses and fungi; blood and serum cells, desquamated epithelial cells; and food debris. 27,28 Therefore, it is thought that the saliva of patients with periodontal disease contains not only pathogenic bacteria and their products but also immunological proteins secreted during the biological response. Saliva samples can be easily collected from patients, and therefore, it can be assessed for the diagnosis of periodontal disease during early-stage clinical trials.…”
Diagnosis of periodontal disease by Fourier transform infrared (FT-IR) microscopic technique was achieved for saliva samples. Twenty-two saliva samples, collected from 10 patients with periodontal disease and 12 normal volunteers, were pre-processed and analyzed by FT-IR microscopy. We found that the periodontal samples showed a larger raw IR spectrum than the control samples. In addition, the shape of the second derivative spectrum was clearly different between the periodontal and control samples. Furthermore, the amount of saliva content and the mixture ratio were different between the two samples. Partial least squares discriminant analysis was used for the discrimination of periodontal samples based on the second derivative spectrum. The leave-one-out cross-validation discrimination accuracy was 94.3%. Thus, these results show that periodontal disease may be diagnosed by analyzing saliva samples with FT-IR microscopy.
“…The IgA1 predominates in serum, teeth and implants, and is a compound of sulcular fluid (3,5), while IgA2 is found in higher concentrations in external secretions like saliva (1,5). Both IgAs are found in saliva and sulcular fluid due to the intimate contact between the secretions (2,3,5,6).…”

“…Both IgAs are found in saliva and sulcular fluid due to the intimate contact between the secretions (2,3,5,6). The high levels of salivary IgA might protect against the development of gingivitis (1,5). In the same way, IgA in sulcular fluid seems to have a protective function (4), which may be related to the lack of complement activation (1,3).…”
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.
