Effect of an Oral Health Promotion Program on Gastroplasty Patients: A Randomized Clinical Trial

Abstract

BACKGROUND: Bariatric surgery can cause oral health problems in individuals, such as an increase in dental caries, periodontal diseases and dental erosion, which can be avoided if oral health promotion actions are implemented. AIMS: To assess the impact of an oral health promotion program implemented among gastroplasty patients. METHODS: This randomized clinical trial involved 208 patients undergoing gastroplasty; they were divided into two groups: Intervention Group, with participation in the Oral Health Promotion Program for Bariatric Patients, or Control Group. Assessments were carried out preoperatively, and six and 12 months postoperatively. The oral conditions assessed were: dental caries, periodontal diseases, tooth wear, dental plaque, and salivary flow. Sociodemographic information was obtained through application of structured questionnaires. For data analysis, the Chi-Square, Fisher’s Exact, and Mann-Whitney tests were performed — α=5%. RESULTS: Patients in the Intervention Group, when compared to those in the Control Group, presented: fewer changes in enamel (6M: p<0.0001; 12M: p=0.001), in dentin (6M: p<0.0001; 12M: p<0.0001), moderate tooth wear (6M=0.002; 12M=0.005), gingival bleeding (6M: p<0.0001), dental calculus (6M=0.002; 12M: p=0.03), periodontal pocket 4-5 mm (6M=0.001; 12M: p=<0.0001); greater reduction in the bacterial plaque index (6M: p<0.0001; 12M: p<0.0001), and increased salivary flow (6M: p=0.019). CONCLUSIONS: The oral health promotion program had a positive impact on the prevention and control of the main problems to the oral health of the gastroplasty patients.
