Oral Health Implications of Bariatric Surgery in Morbidly Obese Patients: An Integrative Review



To identify the implications of bariatric surgery on the oral health of patients with morbid obesity.


Two reviewers independently performed a search of the electronic databases: MedLine, PubMed, SciELO, LILACS, and Scopus, for clinical trials in humans and cohort studies. The search strategy used was Bariatric Surgery and Oral Health or Mouth Disease and Humans and Periodontitis. A total of 26 articles were obtained, and after title screening and full reading, 8 articles were included in this review.


Increased food intake at shorter intervals and increased frequency of regurgitation in these patients were associated with the increased development of dental caries, dental erosion, and increased salivary flow rate.


Intense oral control is recommended for the prevention and early treatment of these conditions and to avoid nonsystemic effects in these patients.
