Obesity and periodontitis: systematic review and meta-analysisObesidade e periodontite: revisão sistemática e meta-análise

No abstract

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.

The aim of this study was to identify the impact of oral disease on the quality of life of morbid obese and normal weight individuals. Cohort was composed of 100 morbid-obese and 50 normal-weight subjects. Dental caries, community periodontal index, gingival bleeding on probing (BOP), calculus, probing pocket depth, clinical attachment level, dental wear, stimulated salivary flow, and salivary pH were used to evaluate oral diseases. Socioeconomic and the oral impacts on daily performances (OIDP) questionnaires showed the quality of life in both groups. Unpaired Student, Fisher’s Exact, Chi-Square, Mann-Whitney, and Multiple Regression tests were used (p<0.05). Obese showed lower socio-economic level than control group, but no differences were found considering OIDP. No significant differences were observed between groups considering the number of absent teeth, bruxism, difficult mastication, calculus, initial caries lesion, and caries. However, saliva flow was low, and the salivary pH was changed in the obese group. Enamel wear was lower and dentine wear was higher in obese. More BOP, insertion loss, and periodontal pocket, especially the deeper ones, were found in obese subjects. The regression model showed gender, smoking, salivary pH, socio-economic level, periodontal pocket, and periodontal insertion loss significantly associated to obesity. However, both OIDP and BOP did not show significant contribution to the model. The quality of life of morbid obese was more negatively influenced by oral disease and socio-economic factors than in normal weight subjects.

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.
