RESUMO
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 prospective study was composed of 50 patients who underwent bariatric surgery and the data collection was performed in three periods pre-operative, 6 (6M) 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.

OBJECTIVES: We evaluate oral health conditions before and after bariatric surgery. METHODS: The sample was composed of 59 patients who had undergone Roux-en-Y gastric bypass (RYGB). Salivary flow, periodontal pocket depth and dental wear were evaluated before and after 6 months of surgery. Body mass index (BMI), C-reactive protein (CRP) and glucose levels were obtained from the patient's medical files. A t-test was used for dependent samples. RESULTS: The mean BMI decreased from 49.31 ± 8.76 to 35.52 ± 8.12 kg/m(2) in 6 months after surgery (P < 0.000). Before surgery, 67% of patients had high levels of CRP and 38% higher blood glucose levels and after surgery there were significant reductions in these levels (P < 0.001). Salivary flow ranged from 0.84 to 0.95 ml/min. There was increased prevalence of periodontal pockets (P = 0.022) and mean pocket depth increased to about 0.5 mm (P < 0.001). The percentage of surfaces with dental wear in dentine was significantly higher after bariatric surgery (P = 0.002), while dental wear in enamel decreased (P = 0.019). CONCLUSIONS: Bariatric surgery may improve systemic conditions. However, it had a negative impact on oral health conditions because of an increase in periodontal disease and dental wear.

The scope of this study was to identify the prevalence of oral manifestations in HIV+/AIDS patients at the DIA Pediatric Hospital of Maputo. All 90 patients were included in the research. Data on dental caries (dmft/DMFT index), soft tissues and saliva flow were analyzed. Information on diet and hygienic habits was obtained in a semi-structured questionnaire. The t- student and chi-square tests were used for statistical assessment. The most frequent oral lesion was candidiasis (5.5%) and upon further oral examination the prevalence of parotid enlargement was 23.0%. The mean dmft 2.6 (SD 3.6) was considerably higher in relation to DMFT of 0.6 (SD 1.6), and the differences between them were statistically significant (P<0.05). The occurrence of mucosal lesions was higher in children who did not take antiretroviral therapy (ART) (p = 0.026). The use of ART is associated with reduced prevalence of oral lesions in HIV+ patients; however, rampant caries were highest in this group. Primary dentition of HIV+ patients should be considered high risk for caries.

To review the effects of obesity surgery on oral health and to present a case report of the periodontal condition of an obese woman who underwent bariatric surgery. A search of studies related to bariatric surgery and oral health was made in PubMed. For case report, BMI, salivary flow, and periodontal condition were evaluated during three different periods. The oral health problems found were dental wear, periodontal diseases, xerostomia, and dental caries. The patient who was evaluated before bariatric surgery and was followed up for 2 years, lost 40.4 kg, presented normal blood glucose levels and controlled hypertension without medication. Salivary flow remained of equal value in the first year, there was an increase in mean probing depth and there existed low bone density in these sites. Patients who have undergone bariatric surgery need to be closely monitored after surgery to prevent the development of oral complications, especially periodontal conditions.
