Association Between Grade(B/C)of Stage III and IV Periodontitis and High Sensitivity C Reactive Protein Level in Serum and Oral Rinse Sample

According to 2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions , the level of high sensitivity c reactive protein has been assumed to increase according to the grade of periodontitis, however, specific evidence regarding this is lacking at present. Moreover, no information is currently available regarding the feasibility of detecting high sensitivity in oral rinse samples, which are relatively easy to collect and store, as compared to more commonly investigated oral fluids like saliva and gingival crevicular fluid Previous literature reports that saliva and gingival crevicular fluid levels of high sensitivity C reactive protein correlate with serum high sensitivity C reactive protein levels, therefore, there is a possibility that high sensitivity C reactive protein in oral rinse samples might also be correlated with serum high sensitivity C reactive protein levels. Measuring high sensitivity C reactive protein in serum and oral rinse samples in systemically healthy individuals with periodontitis could be potentially useful in providing easily accessible information about the systemic burden of periodontal inflammation as well as regarding detection of subclinical systemic inflammation.
