AIM: To investigate the effect of a 16-week whole-food plant-based diet (WPBD) on periodontal parameters in patients with increased cardiometabolic risk.
MATERIALS AND METHODS: A total of 36 participants from a randomized clinical trial received additional periodontal assessment. The intervention group (n = 17) followed a WPBD for 16 weeks, whereas the control group (CG) (n = 19) was instructed not to change their diet. Measurements were assessed at baseline (t1), week 8 (t2) and week 16 (t3). Periodontal examination included bleeding on probing (BOP), periodontal inflamed surface area (PISA) and plaque index (PI) on six index teeth, salivary pH and matrix-matalloproteinase-8 (MMP-8).
RESULTS: At t3, the mean PISA of the index teeth was reduced by 32 mm2 (53.8) in the WPBD group and increased by 22.6 mm2 (45.1) in the CG group (intra-group p = 0.255 and p = 0.977, respectively), BOP changes were similar (intra-group p = 0.89 and p = 0.839, respectively). MMP-8 values reduced in the WPBD group by 50.73 ng/mL (117) and in the CG by 5.40 ng/mL (96.6) (intra-group p = 0.066, p = 0.837, respectively). Difference in change (t3 - t1) between the groups was p = 0.001, p = 0.003 and p = 0.032, respectively. Saliva pH increased in the WPBD group only (intra-group p = 0.007).
CONCLUSION: A trend towards stabilization of the inflammatory parameters (BOP, PISA) was observed in the WPBD group. Because of the non-significant changes within the groups, this study highlights the imperative for future studies.
