Impact of gastroplasty on salivary composition and cytomorphology of oral mucosa: follow-up three and six months

Abstract

The aim of this study is to evaluate the impact of gastroplasty in salivary physicochemical and microbiological composition, concentration of sulfurated compounds volatile related to halitosis and cytomorphology of the oral mucosa of 60 obese adults (18-40 years of age) undergoing gastroplasty (Capella technique) evaluated before and 3 and 6 months after surgery. Thirty normal weight (body mass index between 18.5 and 24.9 kg/m2), matched for sex and age, will be part of the control group, which will also be evaluated three times. The physical examination includes measurements of height, weight, fat mass and skeletal muscle mass through a digital stadiometer and bioelectrical impedance analysis. DMFT and Community Periodontal Index will verify the oral health status. The self- perception of oral health- related quality of life will be verify using OHIP-14 questionnaire. Salivary amylase, total protein, calcium, urea, uric acid, phosphorus, 25-hidroxivitamin D2 and 25 hidroxivitamin D3 concentrations will be determined in stimulated and unstimulated saliva by automated technique (colorimetry or HPLC). ELISA assays will analyze salivary cytokines. Salivary DNA samples will be purified and subjected to quantitative PCR reactions (qPCR) in order to determine the proportion of Selenomonas noxia, Bifidobacteria, Streptococcus mutans and Prevotella intermedia in relation to the total bacterial load. Micronucleus test will analyze oral mucosa cells. The description of the study variables and their correlation will be analyzed using descriptive statistics, normality test and correlation tests (Pearson or Spearman). Principal component analysis will verify the salivary characteristics of the patients at baseline and Two-way ANOVA and Tukey pot-test will be used for comparisons between groups. Two-way ANOVA repeated measures will verify the changes resulting from bariatric surgery (± = 0.05). (AU)
