Bariatric surgery  significantly lowered inflammatory factors ; however , baseline BMI , follow-up duration and type of surgery could impact the extent of observed effects
Obesity is one of the main causes of inflammation .
Previous studies have reported inconclusive results regarding the effect of bariatric surgery on inflammatory markers .
This systematic review and meta- analysis is aim ed at describing the effect of bariatric surgery on C-reactive protein ( CRP ) , interleukin-6 ( IL-6 ) , tumor necrosis factor-α ( TNF-α ) .
Periodontal status and pathogenic bacteria after gastric bypass: a cohort study.
AIM The aim this study was to evaluate the influence of  gastric bypass surgery ( GBS )  on periodontal disease and quantify the periodontopathogenic bacteria in patients undergoing this surgery . MATERIAL AND METHODS This prospect i ve study was composed of 50 patients who underwent bariatric surgery  and the data collection was performed in three periods pre-operative , 6 ( 6 M ) and 12 months ( 12 M ) postoperative . The oral clinical examination to assess periodontal disease ; gingival fluid sample collection for quantification of the periodontopathogenic bacteria Porphyromonas gingivalis , Tannerella forsythia , Treponema denticola , and Prevotella intermedia using q-PCR ; body mass index ( BMI ) and for collection of the individual 's health-related data from medical files . RESULTS There was a significant reduction in serum C-reactive protein ( CRP ) and glucose levels after surgery . The mean probing pocket depth ( PPD ) and clinical attachment level ( CAL ) increased significantly in the postoperative period of 6 months ( p = 0.001 ) . In the same period , the amount of P. gingivalis increased ( p = 0.028 ) and the other bacteria decreased slightly ( p > 0.050 ) . In the presence of P. gingivalis , T. forsythia , T. denticola and P. intermedia , a poor periodontal condition was observed . CONCLUSION The periodontal disease increased in severity and P. gingivalis increased after GBS . A systemic inflammation resolution due to bariatric surgery in obese subjects does not seem to affect the course of periodontal disease
