ALB and periodontal disorder: Furthermore, several reports have demonstrated that serum albumin levels were negatively associated with representative parameters of periodontal health status including plaque index (r = −0.26, p < 0.01), (r = −0.28, p < 0.01), periodontal disease index (r = −0.29, p < 0.01), and pocket depth (r = −0.20, p < 0.05) [10,35], and a multivariate analysis showed that the serum albumin level is an independent predictor of the periodontal disease index (relative ratio = −0.47, CI = −0.91 to 0.03, p = 0.036) [35].
