Abstract

Background: The oral condition of obese patients may change following bariatric surgery owing to adverse effects that cause alterations in the oral cavity. The aim of this study was to evaluate the impact of bariatric surgery on the saliva of patients with morbid obesity. Methods: Whole saliva samples were collected from 27 patients with morbid obesity (BMI >40 kg/m²), prior to and 6 months after bariatric surgery. Stimulated salivary flow rate, pH, buffering capacity, and microbial levels of mutans streptococci, Lactobacillus spp., and Candida albicans were analyzed from saliva. Results: Values of all salivary variables before and after bariatric surgery were within the normal range, except for the level of C. albicans, which was elevated at both times. An increase in the level of mutans streptococci was observed after bariatric surgery (p < 0.05). Conclusions: The results suggest that the salivary levels of mutans streptococci increase following bariatric surgery in morbidly obese patients.
