Oral Health in Individuals After Bariatric Surgery: A Systematic Scoping Review

This scoping review appraises the available literature that investigates oral health after bariatric surgery (BS). Forty-two records were included (33 original studies and 9 systematic reviews). Bariatric surgery had a negative impact on the oral health related quality of life (three out of six studies). Relatively few studies found improvement following BS, probing pocket depth (2/10), clinical attachment level (1/9), bleeding on probing (3/10) and plaque (3/8). Conversely, BS was negatively associated with the DMFT (4/6), tooth wear (4/6) and oral radiographic findings (1/1). There was conflicting evidence regarding salivary parameters. To conclude, the literature on oral health in bariatric surgery patients is continuously growing. Positive as well as negative associations between oral health parameters and bariatric surgery are observed.
