Abstract in Portuguese
A presente pesquisa, dividida em três estudos (EI, EII e EIII), objetivou investigar a influência da obesidade e da cirurgia bariátrica (CB) na ansiedade e na saúde bucal de candidatos à CB. Candidatos à CB constituíram os grupos experimentais (GE) dos três estudos e o grupo controle (GC) do EIII. GC dos EI e EII foram compostos por obesos que não buscavam tratamento para a obesidade e não obesos, respectivamente. Cada estudo foi composto por 100 indivíduos divididos em GE e GC. Em EI e EIII, tipos longitudinais prospectivos, GE e GC foram avaliados em duas etapas: GE - antes CB (T0) e um ano após CB (T1); GC - inicial (T0) e um ano após inicial (T1). Foram avaliadas as variáveis: fluxo salivar (em EI); profundidade de sondagem, recessão gengival, nível de inserção clínica, periodontite, cálculo e sangramento gengival (em EII); lesões iniciais de cárie dentária - LIC e sangramento gengival (em EIII). Características sociodemográficas, comportamentais e antropométricas, ansiedade (medida pelo Inventário de Ansiedade Traço-Estado - IDATE), e presença de diabetes/hipertensão foram utilizadas nos três estudos. Para a análise dos dados foram utilizados os testes Exato de Fisher, Qui-quadrado, Mann-Whitney, Kruskal-Wallis (Dunn), e two-way Anova (Sidak), além de análises de regressão, linear e logística, e cálculos de risco relativo (RR) e taxa de incidência (IR). O nível de significância foi de 5%. Em ambos os EI e EIII, estado e traço de ansiedade não diferiram entre GC e GE, nem entre T1 e T0. No entanto, GC, em EII, apresentou maior ansiedade-traço do que GE (p = 0,0004). Em El, fluxo salivar não foi influenciado nem pelos grupos (p = 0,29) nem pelo tempo (p = 0,81). Em EII, GE teve mais casos de profundidade de sondagem entre 4 a 5 mm (p = 0,0006) do que GC, mas a presença de sangramento gengival foi mais frequente no GC (p = 0,0139). Em EIII, o número de dentes com LIC (p = 0,0013) e sangramento gengival (p = 0,0096) aumentou após um ano de CB. No entanto, CB não foi considerada fator de risco para LIC (RR = 0,86, p = 0,3439) e sangramento gengival (RR = 1,14, p = 0,4008). Concluiu-se que ambos os indivíduos, obesos e bariátricos, mostraram vulnerabilidade aos desfechos estudados, sendo necessária a participação do profissional de odontologia na equipe de atendimento a esses pacientes.

Abstract in English
The present study was designed to observe the influence of obesity and bariatric surgery (BS) in anxiety and oral health of BS candidates. It was divided into 3 experimental designs (EI, EII and EIII). BS candidates constituted the experimental groups (EG). Control group (CG) of EI and EII were obese subjects not seeking treatment for obesity and non-obese subjects, respectively. Each study was composed of 100 subjects divided into EG and CG. In EI and EIII, both prospective longitudinal studies, EG and CG were evaluated in two stages: EG - before BS (T0) and one year after BS (T1); CG - baseline (T0) and one year after baseline (T1). The following outcomes were evaluated: salivary flow (only in EI); probing depth, gingival recession, clinical attachment level, periodontitis, calculus and gingival bleeding (for EII); initial lesions of dental caries ILDC, and gingival bleeding (for EIII). Sociodemographic, behavioral, anthropometric characteristics and the presence of diabetes/hypertension were determined in all experiments. Anxiety was measured by State-Trait Anxiety Inventory. Data analysis was performed by Exact Fisher, Chi-square, Mann-Whitney, Kruskal-Wallis (Dunn), and two-way Anova (Sidak) tests. In addition, linear and logistic regression analysis and calculations of relative risk (RR) and incidence rate (IR) were also used. Significance level was set at 5%. In both EI and EIII, state and trait anxiety did not differ between CG and EG, nor among T1 and T0. However, CG showed higher trait anxiety than EG (p=0.0004) in EII. In EI, salivary flow was not influenced by groups (p = 0.29) or time (p = 0.81). In EII, EG had more cases of probing depth between 4 to 5 mm (p = 0.0006) than CG, but the presence of gingival bleeding was more frequent in CG (p = 0.0139). In EIII, the number of teeth with ILDC (p = 0.0013) and gingival bleeding (p = 0.0096) increased after one year of BS. However, BS was not considered a risk factor for ILDC (RR = 0.86, p = 0.3439), and gingival bleeding (RR = 1.14, p = 0.4008). It was possible to conclude that both obese and BS subjects showed vulnerability to the studied outcomes, requiring dental professionals on care-staff to treat these patients.
