Only two studies evaluated other periodontal parameters, such as gingival crevicular inflammatory mediators, specifically Interleukin (IL-)1B [39,42], IL-10 [42]and Myeloperoxidase (MPO) [42], and no studies considered either radiographic outcomes (bone loss), tooth loss due to periodontitis, nor the number of residual teeth. This evidence concerns the gene IL10 and periodontitis.
