OBJECTIVE: To review and analyze periodontal clinical parameters after bariatric surgery.
Background: Periodontitis, a dysbiotic inflammatory disease has been associated with obesity. The purpose of bariatric surgery is to reduce weight and systemic inflammation. Consequently, it is of interest to systematically review the impact of bariatric surgery on periodontal status.
Methods: Electronic searches were conducted in MEDLINE, EMBASE, Thesis database and the Cochrane Library databases. Grey literature and the main journals of both specialties were also reviewed. Only cross-sectional and prospective studies focusing on bleeding on probing, pocket depth and clinical attachment levels were selected.
Results: After thorough screening of 651 studies, 10 studies were selected by two independent reviewers. Four studies (n=250) and 3 studies (n = 191) were included in the meta-analysis at 6 and 12 months follow-up, respectively. At 6-month follow-up increased periodontal inflammation (p = 0.03) and periodontal destruction were observed. However, 12 months after baseline, the difference between bariatric subjects and control was no longer significant.
Conclusion: The present systematic review and meta-analysis suggests that deterioration of periodontal status may be observed in the first 6 months’ after surgery. Consequently, periodontal screening and management of the patient’s request for bariatric surgery should be recommended to avoid further deterioration of periodontal status after bariatric surgery.
