ABSTRACT PURPOSE:To evaluate oral changes, such as dental caries, periodontal disease, dental wear and salivary flow in bariatric patients. Fifty four obese patients who underwent bariatric surgery were studied before (n=54), up after 3 months (n=24) and 6 months (n=16). METHODS: Indices for evaluating oral conditions were: DMFT, CPI, DWI and salivary flow. OIDP questionnaire was used to assess the impact of oral health on quality of life. ANOVA and Spearman correlation were used (p<0.05). RESULTS: DMFT was 17.6±5.7, 18.4±4.1 and 18.3±5.5 (P>0.05), presence of periodontal pockets in 50%, 58% and 50% of patients (p>0.05), tooth wear in dentin present in 81.5%, 87.5% and 87.5% before, 3 and 6 months after surgical treatment respectively. There were differences between the three periods for prevalence and severity of dental wear (p = 0.012). Salivary flow was 0.8±0.5 ml/min before surgery, 0.9±0.5 ml/min for 3 months and 1.1±0.5m/min for 6 months (p>0.05). The impact of oral health on quality of life decreased with time after bariatric surgery (p= 0.029). CONCLUSION: The lifestyle changes after bariatric surgery and these changes may increase the severity of pre-existing dental problems. However, these alterations in oral health did not influence the quality of life. Key words: Oral Health. Tooth Erosion. Dental Caries. Xerostomia. Obesity. Bariatric Surgery. RESUMO OBJETIVO:Avaliar alterações bucais, como cárie dentária, doença periodontal, desgaste dentário e fluxo salivar, em pacientes bariátricos. MÉTODOS: Cinquenta e quatro pacientes obesos, submetidos à cirurgia bariátrica, tiveram suas condições bucais avaliadas antes (n=54), aos 3 meses (n=24) e aos 6 meses (n=16) após a cirurgia bariátrica. Os índices para avaliação das condições bucais foram: CPOD, IPC, IDD e o volume de fluxo salivar. O questionário OIDP foi utilizado para verificar o impacto da saúde bucal na qualidade de vida. ANOVA e correlação de Spearman foram utilizados para análise estatística (p<0,05). RESULTADOS: CPOD foi 17,6±5,7, 18,4±4,1 e 18,3±5,5 (p>0,05), bolsa periodontal foi encontrada em 50%, 58% e 50% dos pacientes (p>0,05) e o desgaste dentário em dentina em 81,5%, 87,5% e 87,5% dos pacientes, respectivamente antes, 3 meses e 6 meses após a cirurgia bariátrica. Houve diferença significativa entre os três períodos estudados, quanto à prevalência e à severidade do desgaste dentário (p=0,012). O fluxo salivar foi 0,8±0,5 ml/min antes, 0,9±0,5 ml/min aos 3 e 1,1±0,5 ml/min aos 6 meses após cirurgia (p>0,05). O impacto da saúde bucal na qualidade de vida diminuiu com o tempo decorrido após cirurgia bariátrica (p=0,029). CONCLUSÕES: As mudanças no estilo de vida após a cirurgia bariátrica podem aumentar a gravidade de problemas bucais pré-existentes. Entretanto, esta alteração na condição bucal pode não influenciar a qualidade de vida.

Background: As the number of surgeries increases and the elapsed time of the realization increases as well, the postoperative evaluations would become increasingly necessary. Aim: To assess the psychological profile before and after surgery. Methods: Were evaluated 281 patients from the public service of bariatric surgery. In this study, 109 patients completed the evaluations before surgery (T0) and up to 23 months after surgery (T1); 128 completed the evaluations in T0 and between 24 months and 59 months after surgery (T2); and 44 completed the evaluations in T0 and 60 months after surgery (T3). A semi-structured interview, the Beck Depression Inventory (BDI), Beck Anxiety (BAI), and the Binge Eating Scale (BES) were used. Results: There was a higher prevalence of female (83%), patients with less than 12 years of education (83%), and patients who have a partner (64%). Analyzing all times of evaluation, regarding anxiety, depression, and binge eating, there was a reduction in all symptoms in T1, pointing to significant improvements in the first 23 months after surgery. Already, in T2 and T3, there was an increase in all indicators of anxiety, depression, and binge eating pointing to the transient impact of weight loss or bariatric surgery on these symptoms. Conclusions: This study shows the importance of the continuous psychological evaluation and needs for the appropriate interventions for these patients who have undergone bariatric surgery, even after weight loss.

ABSTRACT-Background -Bariatric surgeries have been considered an alternative for treatment of morbid obesity. Some adverse events that people experience after the treatment frequently are the consequence of the lack of consistent knowledge associated with psychosocial factors that are related to the pre-surgery status of the patients. Aim -To evaluate psychosocial variables of 414 candidates for bariatric surgery from Clinical Hospital of Medical School at University of São Paulo, Ribeirão Preto, SP, Brazil. Methods -Semi-structured interview, Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI) and Binge Eating Scale (BES) were used. Results -BMI was higher among patients who had no employment (p = 0.019). Female, patients who had a partner and patients with a BMI < 50 kg/m², all of them desired have a lower weight (p < 0.001). BAI scores were higher among patients who had no employment (p < 0.05) and higher among those with a BMI > 50 kg/m² (p < 0.05). BDI scores were higher among women (p < 0.05) and lower among those who had an employment (p < 0.01). No difference in BES was found. Conclusions -The data suggest that women showed higher indicators of anxiety and depression, suggesting that they had a more fragile psychological functioning with difficulties in coping with distress. Self-perception as well as skills and abilities, may reflect internal aspects of individual's personality. Patients who had an employment before surgery seemed have more emotional resources. So, they may feel less distress because the employment may protect them. Women and those who did not have an employment were more likely to experience depression symptoms. Furthermore, patients who did not have an employment and those with BMI> 50 kg / m² were more likely to experience anxiety symptoms. ABCDDV/798RESUMO -Racional -Operações bariátricas têm sido consideradas alternativa para o tratamento de obesidade mórbida. Alguns eventos adversos que as pessoas experimentam após o tratamento frequentemente são consequência da falta de conhecimento consistente associada a fatores psicossociais que estão relacionadas ao status pré-operatório dos pacientes.

Background: The psychologist who works in bariatric surgery has a role to receive, evaluate, prepare and educate the patient who will undergo the surgical procedure. Psychological evaluation becomes important in so far as allows us to obtain data on personal and familiar history and allow tracing of possible psychopathology. Aim: To collect data on psychological evaluations of patients in a bariatric surgery service of a public hospital in order to describe the psychological profile of patients in this service. Method: Data were collected from 827 patients between 2001 and 2015, using data from an interview, Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI) and Binge Eating Scale (BES). Results: The mean age of patients before surgery was 39 years+/- 10, the mean BMI was 51 kg/m²+7, and most patients (81%) were female. The average score on the BDI was 14.8+8 and women had significantly higher scores than men. On the BAI the average score was 11+8 and on the ECAP was 14+8, both with no difference between groups. Conclusions: Psychosocial characteristics of the patients points to the significant presence of indicators of depression, with low levels of anxiety and binge eating.
