Sensitivity and Specificity of Capsules Containing Fuchsin-Based Beads for the Evaluation of Masticatory Performance.

PURPOSE: To determine the sensitivity and specificity of capsules containing fuchsin-based beads for evaluating masticatory performance. MATERIALS AND METHODS: A total of 60 healthy subjects (mean ± SD age: 41.0 ± 13.2 years) were categorized according to number of occlusal pairs (n = 15 per group) as follows: 16-14 (control group); 13-10; 9-6; and 5-1. The subjects chewed the capsules to assess masticatory performance, which was defined as the concentration of fuchsin released and measured using ultraviolet-visible spectrophotometry. The subjects also comminuted silicone cubes, and median size was calculated via the sieving method. The test foods were compared using analysis of variance, receiver operating characteristic (ROC) curve, and Bland-Altman analysis. RESULTS: The control group presented the highest masticatory performance for chewing the capsules (P < .05), except when compared to the 13-10 occlusal pairs group (P = .667). There was no difference between the partial edentulism groups (P > .05). An acceptable area under the ROC curve of 0.744 was observed, with 73.33% sensitivity and 70.00% specificity. The control group also showed the best results for chewing the cubes (P < .01); however, the 9-6 and 5-1 groups were equivalent (P = .133). An excellent area under the ROC curve of 0.887 was found, with 80.00% sensitivity and specificity. The bias between the capacity of both test foods to recognize subjects with < 10 occlusal pairs was -3.56%. CONCLUSION: Capsules containing fuchsin-based beads were viable for evaluating masticatory performance, as they showed sufficient sensitivity and specificity for characterizing subjects presenting with < 10 occlusal pairs.

Stomathognatic system function in indigenous people from Brazilian Xingu villages: An electromyographic analysis.

The maintenance of postural balance can be influenced by the lifestyle of a population. This study aimed to determine the electromyographic activity of the masseter and temporalis muscles during mandibular tasks and habitual and non-habitual chewing in indigenous individuals to reveal the differences among white Brazilian individuals. Sixty Brazilians (18 and 28 years) were divided into two groups: 30 Xingu indigenous individuals and 30 white Brazilian individuals, with 20 men and 10 women in each group. The individuals were assessed using the normalized electromyographic activity of mandibular tasks (rest, protrusion, right and left laterality) and electromyographic activity of masticatory cycles in habitual (peanuts and raisins) and non-habitual (Parafilm M) chewing. Data were analyzed using Student's t-test (p < .05). Comparisons between the groups demonstrated significant differences. Indigenous individuals group presented a decrease in the normalized electromyographic activity of the masticatory muscles during mandibular rest [right masseter (p = .002) and left masseter (p = .004) muscles]. There was increase in the normalized electromyographic activity during protrusion [left temporal (p = .03) muscle]. There was increase in the electromyographic activity during chewing: peanuts [right masseter (p = .001), left masseter (p = .001) and right temporal (p = .01) muscles], raisins [right masseter (p = .001), left masseter (p = .002), right temporal (p = .008), left temporal (p = .01) muscles] and Parafilm M [left masseter muscle (p = .05)]. From the findings of this study, we concluded that in the comparison between indigenous and white individuals, positive changes were observed in the electromyographic pattern of the masticatory muscles in the mandibular postural conditions, with greater masticatory efficiency in the indigenous group.

A práxis desenvolvida no âmbito do Conselho Municipal de Saúde em um município de São Paulo / The praxis developed in the Municipal Health Council in a large city in the state of São Paulo

RESUMO Os objetivos deste estudo foram caracterizar as modalidades de práxis desenvolvidas pelo Conselho Municipal de Saúde de Ribeirão Preto e investigar o exercício do papel do conselheiro enquanto membro participativo da gestão pública. Trata-se de um estudo descritivo com abordagem qualitativa, com coleta de dados em fontes primárias, por meio de questionários aplicado aos(às) conselheiros(as) de saúde, e secundárias, com análise das atas no período 2018-2019. Para análise dos dados, utilizaram-se a análise documental e o software IRaMuTeQ. Participaram deste estudo seis conselheiros, e foram analisadas 27 atas de reuniões. Embora o Conselho Municipal de Saúde se institua como espaço para o exercício do controle social, identificou-se falsificação de sua profecia inicial, uma vez que não houve entendimento do papel de conselheiros enquanto representante e sujeito político, observaram-se deliberações de baixo impacto, não houve estímulo da participação do cidadão, notou-se a utilização de um discurso técnico/científico como forma de estabelecer relações de subordinação, coerção de representantes pelo segmento governamental e uma participação pró-forma, reduzindo sua atuação à ocupação daquela cadeira. Entretanto, os Conselhos deveriam ser espaços ricos e potentes para a efetivação do Sistema Único de Saúde.

ABSTRACT This study aimed to characterize the praxis modalities developed by the Municipal Health Council of Ribeirão Preto and investigate the exercise of the role of the councilor as a participatory member of public management. It is characterized by a descriptive study with a qualitative approach with data col- lection and analysis from primary sources through questionnaires with a health counselor, and secondary sources, through analysis of the minutes in the period 2018-2019. For data analysis, we used a documentary analysis and the IRaMuTeQ software. Six counselors participated in this study and 27 minutes of meetings were analyzed. Although the Municipal Health Council is established as a space for the exercise of social control, falsification of its initial prophecy was identified, since there was no understanding of the role of counselors as a representative and political subject, low-impact deliberations were observed, there was no stimulus of citizen participation, the use of a technical/scientific discourse was noted as a way of establish- ing relationships of subordination, coercion of representatives by the governmental segment and a proforma participation, reducing their performance to the occupation of that chair. However, councils should be rich and powerful spaces for the implementation of the Unified Health System.

Alterations in masticatory cycle efficiency and bite force in individuals with periodontitis.

OBJECTIVES: The objective of this research was to evaluate the effect of periodontitis on masticatory cycle efficiency and maximum molar bite force. METHODS: Twenty-four individuals were divided into two groups: With periodontitis (Group I; mean age ± standard deviation (SD), 51.3 ± 2.8 years; n = 12) and without periodontitis (Group II; mean age ± SD, 48.9 ± 2.4 years; n = 12). Masticatory cycle efficiency was obtained from the value of the ensemble-averaged integrated linear envelope electromyographic signal of the masseter and temporalis muscles. Maximum bite force was recorded for the right and left molar regions. The data were tabulated and submitted to statistical analysis (P ≤ 0.05). RESULTS: There was a significant difference between the groups for the left masseter muscle when chewing raisins (P = 0.04), peanuts (P = 0.02), and biocapsules (P = 0.01). Multiple regression analysis demonstrated the influence of dental mobility on masticatory cycle efficiency for peanuts (P = 0.03) and biocapsules (P = 0.01). The maximum bite force for the left molar region was significantly different between the groups (P = 0.02). Dental mobility was a variable that had a greater effect on masticatory cycle efficiency. The periodontitis group had a reduced bite force. CONCLUSION: The present study findings indicate that the loss of periodontal supporting structures had a negative impact on masticatory cycle efficiency and molar bite force. This finding suggested that dental mobility should be considered when determining clinical treatments aimed at improving masticatory efficiency and bite force in individuals with the periodontal disease.

Promoção da saúde e efetivação da Reforma Sanitária no contexto dos povos originários / Health promotion and accomplishment of Health Care Reform in the context of indigenous populations

RESUMO O Brasil teve atos e políticas excludentes que levaram à quase dizimação dos variados povos indígenas. Buscando voz e inclusão, o movimento dos povos originários contou com a presença de representantes das próprias comunidades para a consolidação da Reforma Sanitária nesse contexto. Conselheiros indígenas de saúde e agentes indígenas de saúde fomentam a resiliência para reivindicar, proteger e curar relações, lidando com a perspectiva biomédica, e atuação de profissionais não indígenas. Este trabalho objetiva evidenciar as aprendizagens colaborativas e práticas interdisciplinares no atual sistema de saúde brasileiro, para a promoção da saúde dos povos originários. Em uma revisão integrativa, propôs-se discorrer sobre o impacto da formação profissional com ênfase na questão étnica, possibilidades de atuação não colonizadora e inclusiva, e a contribuição dos diversos atores, indígenas ou não, que possibilitam a consolidação desse subsistema de atenção, considerando suas especificidades e sua maneira própria do fazer da saúde. A autonomia, com foco no empoderamento, fortalecida por meio do reconhecimento do papel fundamental dos próprios indígenas e de pessoas ligadas à causa indigenista que se estabeleceram para tal assistência, consolidaram a Reforma Sanitária também nesses territórios, na tentativa de universalidade no acesso, integralidade da atenção, promoção da equidade e redução de iniquidades.

ABSTRACT Brazil has always had historic practices and excluding politics that almost decimated the varied indigenous peoples. Seeking a voice and inclusion, the movement of original populations counted on the presence of communities' representatives to consolidate the Health Care Reform. Health indigenous advisors and indigenous heath agents promoted resilience to claim, protect, and cure relations, dealing with the biomedical perspective, and the performance of non-indigenous professionals. The present study aims to emphasize interdisciplinary placement and collaborative learnings among original populations' heath actors in the current Brazilian health system for the promotion of health among original peoples. Through an integrative review, it was proposed a glossing over the impact of professional qualification emphasizing ethnic issues and practices proper to such context, possibilities of a non-colonizational and inclusive actuation, and the contribution of several actors, indigenous or not, that made such health sub-system possible, considering its specificities and its own way of working in health. Autonomy, focused on empowerment, strengthened by the recognition of the essential role of indigenous peoples and non-indigenous contributors established for such health assistance, consolidated Health Reform also in these territories, trying to achieve universality in service access, integrality of care, promotion of equity, and reduction of inequities.

Utilização de serviços de saúde bucal na atenção primária: perspectivas dos usuários do sus de um município do sul do brasil / Use of dental services at primary health care: sus users perspective at a municipality in south of Brazil

Introdução: A questão do acesso aos serviços de saúde bucal no Sistema Único de Saúde, bem como a característica da busca por estes serviços refletem a necessidade de saúde bucal da população. Objetivo: O objetivo do presente estudo é analisar o acesso ao atendimento odontológico em Porto Alegre/RS, por meio da percepção do usuário dos serviços de saúde do SUS. Métodos: Trata-se de um estudo transversal, de base populacional, desenvolvido por meio da aplicação de um questionário em uma amostra de 139 participantes por meio do aplicativo Open Data Kit-Collect. Foram analisadas as variáveis sexo, faixa-etária, escolaridade, raça/cor, motivo da consulta odontológica e informação sobre a presença de atendimento odontológico na Unidade Básica de Saúde acessada. Foram realizadas análises descritivas simples e teste Qui-quadrado de Person. Resultados: Dos participantes, 66,3% eram do sexo feminino, autodeclaradas não-brancas (73,4%), casadas (44,4%) e 100% alfabetizadas. Do total destes usuários do SUS, 87,4% buscavam atendimento odontológico privado mesmo sendo usuários dos serviços de Atenção Primária à Saúde do SUS. Os principais motivos de suas consultas odontológicas (54%) eram referentes a realização de limpeza, revisão, manutenção ou prevenção. Observou-se que 35% não sabia da existência de serviços odontológicos na unidade de saúde que acessavam. Desse modo, pode-se sugerir que os usuários de unidades básicas de saúde, que utilizam serviços odontológicos privados, não sabiam que a unidade ofertava serviços odontológicos preventivos (p=0,001). Conclusão: O referido estudo oportunizou o aprofundamento e caracterização sobre situação do acesso à saúde bucal de uma grande cidade brasileira. Esta análise contribui não só para a percepção do acesso a saúde bucal no município de Porto Alegre, como também, possibilitará o estabelecimento de estratégias que visem uma melhor abrangência do atendimento odontológico para essa população no SUS (AU).

Introduction: The issue of access to oral health services in the Unified Health System as well as the characteristic of the search for these services reflect the need for oral health of the population. Objective: The aim of the present study is to analyses the access to dental care, by means of the perception of the user of Unified Health System (Acronym in Portuguese is SUS) health services, in Porto Alegre. Methods: This is a cross-sectional, population-based study developed by means the application of a questionnaire built specifically for the research, in a sample of 139 individuals through the app Open Data Kit-Collect. The following variables were analyzed: Sex, Age-group, Schooling, Race/color, reason for dental consultation and information about the attendance of dental care in the UBS accessed. Simple descriptive analyses and the Chi-square test of Person were performed. Results: 66.3% of the participants were female, self-declared white (73.4%), married (44.4%) and single (31.3%) and literate. It could be observed that 87.4% of these SUS users, when necessary, sought private dental care, even though they were users of SUS Primary Health Care services. The main reason for their dental consultations (54%) were for reasons related to cleaning, revision, maintenance or prevention. It was observed that 35% did not know about the existence of dental services in the Health Unit that they accessed. Thus, it can be suggested sers of basic health units, who use private dental services, did not know that the unit offered preventive dental services (p= 0.001). Conclusion: This project provided the knowledge about the situation of access to oral health in a large Brazilian city. This analysis contributes not only to the perception of access to oral health in the city of Porto Alegre, but also, it will enable the establishment of strategies aimed at a better coverage of dental care for this population in the SUS (AU).

O estudo teve por objetivo analisar as percepções de estudantes de Odontologia sobre a experiência em um estágio não obrigatório no sistema público de saúde brasileiro em um município de São Paulo e sua contribuição na formação profissional. Trata-se de um estudo descritivo, de natureza qualitativa com estudantes de uma universidade pública, no período de 2013-2015. Foram realizadas entrevistas semidirigidas que foram gravadas e transcritas. Os dados foram sistematizados e analisados por meio da técnica da Análise de Conteúdo na perspectiva temática com suporte teórico das Diretrizes Curriculares Nacionais para o Curso de Odontologia. Observou-se que os estudantes perceberam o estágio como uma oportunidade para vivenciar a realidade do trabalho nos serviços de saúde, desenvolveram e aperfeiçoaram habilidades e competências como comunicação, gerenciamento e organização de seu trabalho e construção de sua identidade profissional. Conclui-se que os estudantes se aproximaram dos conceitos de atenção à saúde, humanização, autonomia e aprendizagem no trabalho, experiência que se mostrou significativa (AU).

This study aimed to analyze the perceptions of Dental undergraduate students about the experience in a non-mandatory internship in the Brazilian Public Health System, in a municipality of São Paulo, Brazil, and its contribution to professional education. We performed a descriptive study in a qualitative approach with undergraduate students of a public university, from 2013 to 2015. Semi-structured interviews were conducted, audio-recorded and transcribed. The data were organized and analyzed using Content Analysis technique in the thematic perspective with the theoretical support of the National Curriculum Guidelines for Dentistry Course (Diretrizes Curriculares Nacionais). The undergraduate students perceived the internship as an opportunity to experience the work reality in health services, developed and improved skills and competencies like communication, management and organization of their work, and construction of their professional identity. In conclusion, the students came closer to the concepts of health care, humanization, autonomy and learning at work, experiences that emerged as significant for them (AU).

Influence of dentistry procedures on masticatory function of dentate patients

Aim: Evaluate the masticatory performance in patients with different clinical situations: patients with natural dentition without restorative and/or orthodontic intervention (Group CG) and patients with restorations and/or orthodontic intervention (Group TG). Subjects received instruction before the experiment, related to masticatory movements. Methods: Three capsules containing the granules were delivered separately to chew for 20 seconds each, controlled by the examiner. One capsule was chewed for 20 seconds only on the left side; the second capsule was chewed for 20 seconds only on the right side; and the third capsule was chewed for 20 seconds to simulate each patient's mastication. The mean data and standard deviation of masticatory function of each patient was calculated. Results: The results obtained in this study showed that there were no statistically significant differences (P < 0.05) between both tested groups (0.0320 ± 0.00716, 0.0436 ± 0.00974). Conclusions: Patients who were submitted to orthodontic and/or restorative procedures, with balanced occlusion could be used as a control group, making easier the patient recruitment. Clinicians and researchers on masticatory performance evaluation could apply the colorimetric method. The colorimetric method was a standardize method, effective and easy to execute. (AU)

Reproducibility, Reliability, and Validity of Fuchsin-Based Beads for the Evaluation of Masticatory Performance.

PURPOSE: Rehabilitation of masticatory function is inherent to prosthodontics; however, despite the various techniques for evaluating oral comminution, the methodological suitability of these has not been completely studied. The aim of this study was to determine the reproducibility, reliability, and validity of a test food based on fuchsin beads for masticatory function assessment. MATERIALS AND METHODS: Masticatory performance was evaluated in 20 dentate subjects (mean age, 23.3 years) using two kinds of test foods and methods: fuchsin beads and ultraviolet-visible spectrophotometry, and silicone cubes and multiple sieving as gold standard. Three examiners conducted five masticatory performance trials with each test food. Reproducibility of the results from both test foods was separately assessed using the intraclass correlation coefficient (ICC). Reliability and validity of fuchsin bead data were measured by comparing the average mean of absolute differences and the measurement means, respectively, regarding silicone cube data using the paired Student's t-test (α = 0.05). RESULTS: Intraexaminer and interexaminer ICC for the fuchsin bead values were 0.65 and 0.76 (p < 0.001), respectively; those for the silicone cubes values were 0.93 and 0.91 (p < 0.001), respectively. Reliability revealed intraexaminer (p < 0.001) and interexaminer (p < 0.05) differences between the average means of absolute differences of each test foods. Validity also showed differences between the measurement means of each test food (p < 0.001). CONCLUSIONS: Intra- and interexaminer reproducibility of the test food based on fuchsin beads for evaluation of masticatory performance were good and excellent, respectively; however, the reliability and validity were low, because fuchsin beads do not measure the grinding capacity of masticatory function as silicone cubes do; instead, this test food describes the crushing potential of teeth. Thus, the two kinds of test foods evaluate different properties of masticatory capacity, confirming fushsin beads as a useful tool for this purpose.

Does a mandibular RDP and new maxillary CD improve masticatory efficiency and quality of life in patients with a mandibular Kennedy class I arch?

OBJECTIVES: To evaluate the change in masticatory efficiency and quality of life of patients treated with mandibular Kennedy class I removable partial dentures (RPDs) and maxillary complete dentures at the Department of Dentistry of the Federal University of Rio Grande do Norte. MATERIALS AND METHODS: A total of 33 Kennedy class I patients were rehabilitated with maxillary complete dentures, and mandibular RPDs were selected for this non-randomized prospective intervention study. The patients had a mean age of 59.1 years. Masticatory efficiency was evaluated by colorimetric assay using fuchsin capsules. The measurements were conducted at baseline and 2 and 6 months after prosthesis insertion. Quality of life was evaluated using the Oral Health Impact Profile (OHIP-14) at baseline and 6 months after denture insertion. The Kolmogorov-Smirnov normality test was applied. Masticatory efficiency was evaluated by repeated measures ANOVA. Oral health-related quality of life was compared using the paired t test. RESULTS: There was no statistically significant difference in masticatory efficiency after denture insertion (p = 0.101). Significant differences were found (p = 0.010) for oral health-related quality of life. A significant improvement in psychological discomfort (p < 0.01) and psychological disability (p < 0.01) was observed. Mean difference value (95 % confidence interval) was 6.8 (3.8 to 9.7) points, reflecting a low impact of oral health on quality of life, considering the 0-56 range of variation of the OHIP-14 and a Cohen's d of 1.13. CONCLUSION: According to the results of the present study, rehabilitation with Kennedy class I RPDs and complete dentures did not influence masticatory efficiency but improved oral health-related quality of life. CLINICAL RELEVANCE: The association between the patient's quality of life and the masticatory efficiency is important for treatment predictability.

Impact of mandibular conventional denture and overdenture on quality of life and masticatory efficiency

Abstract The aim of this non-randomized controlled clinical trial was to evaluate the oral health-related quality of life and masticatory efficiency of patients rehabilitated with mandibular two-implant overdentures with immediate loading or conventional dentures. Fifty completely edentulous patients wearing bimaxillary conventional dentures, for at least one year, were recruited. The patients were then assigned to either two treatment groups: mandibular overdentures supported by two implants with bar-clip system and a maxillary conventional denture (n = 25), and new maxillary and mandibular conventional complete dentures (n = 25). Masticatory efficiency and oral health-related quality of life were assessed before and 3 months after denture insertion. The Brazilian version of OHIP-Edent questionnaire was used to assess the oral health-related quality of life. Masticatory efficiency was evaluated with chewing capsules through a colorimetric method. The results revealed fewer oral health-related quality of life problems in patients wearing mandibular two-implant overdentures compared to the conventional dentures group. In addition, the implant overdenture group presented statistically significant improvement in masticatory efficiency (p = 0.001). There was no correlation between masticatory efficiency and OHIP in the implant group (p > 0.05), however a correlation was found in the conventional denture group (p < 0.05). Therefore, these short-term results suggest that mandibular overdenture retained by 2 implants with immediate loading combined with maxillary conventional dentures provide better masticatory efficiency and oral health-related quality of life than mandibular conventional dentures.

Is the Masticatory Function Changed in Patients with Temporomandibular Disorder?

Patients with temporomandibular disorders (TMD) often complain and have limitation in masticatory function, which can be affected by a complex interaction of factors. The aim of this study was analyze the masticatory function in patients with TMD using surface electromyography (EMG) and masticatory efficiency (ME). Twenty-seven patients with TMD and 25 considered control (n), aged between 18 and 60 years, paired by age and gender, were evaluated according to RDC/TMD. In both groups were performed: EMG with chewing gum, clinical evaluation of habitual chewing with stuffed cookie (CE) (number of chewing strokes and time) and analysis of ME with fuchsin beads. Nonparametric statistical analyses were used (Mann-Whitney) for comparisons between groups, with 5% significance level. For all variables, the TMD group showed higher values than the control, with statistical significance for ME (p<0.0001), number of chewing strokes (p=0.04), chewing time (p=0.009), right masseter EMG activity (p=0.05), left masseter (p=0.005), right anterior temporal (p=0.05) and left anterior temporal (p=0.001). The conclusion is that patients with TMD showed changed chewing pattern, but without impairment of masticatory function.

Pacientes com disfunção temporomandibular (DTM) frequentemente se queixam e apresentam limitação na função mastigatória, a qual pode ser afetada por uma complexa interação de fatores. O objetivo deste estudo foi analisar a função mastigatória de pacientes com DTM em comparação a sujeitos controle por meio das técnicas de eletromiografia de superfície e eficiência mastigatória (EM). 27 pacientes com DTM e 25 considerados controle (n), com idade entre 18 e 60 anos, pareados por idade e gênero, foram avaliados segundo o RDC/TMD. Em ambos os grupos foram realizados: exame de eletromiografia de superfície da mastigação habitual com goma de mascar (EMG), avaliação fonoaudiológica da mastigação habitual com biscoito recheado (AF) (número total de golpes mastigatórios e tempo) e análise da eficiência mastigatória com o sistema de cápsulas compostas por beads de fucsina (EM). Foi empregada estatística não paramétrica (Mann-Whitney) para a comparação intergrupos, adotando-se 5% como nível de significância. Para todas as variáveis estudadas o grupo DTM apresentou valores superiores em relação ao grupo controle, com significância estatística: EM (p<0,0001), número total de golpes (p=0,04), tempo de mastigação (p=0,009), atividade eletromiográfica masseter direito (p=0,05), masseter esquerdo (p=0,005), temporal anterior direito (0,05) e temporal anterior esquerdo (p=0,001). Conclui-se que pacientes com DTM apresentam um padrão mastigatório alterado porém, sem comprometimento da função mastigatória.

Oral health conditions and quality of life of elderly users of the Unified National Health System / Condições de saúde bucal e qualidade de vida de idosos usuários do Sistema Único de Saúde

OBJECTIVE: This study aimed to analyze the oral health status and socio-economic conditions of the elderly, which are users of the Brazilian Unified Public Health System (SUS) and its relationship to a subjective indicator of impacts of oral conditions on quality of life (Oral Health Impact Profile OHIP-14). METHODS: It is a descriptive cross-sectional exploratory study developed in the second semester of 2011. The sample consisted of 76 elderly (65-74 years old) users of the public dental service at the Dental Specialties Center at the Faculty of Dentistry of Ribeirão Preto, Brazil. The methodological strategy adopted for data collection was the structured interview and secondary data were obtained from medical records and reports. To perform the statistical analysis it was used an exploratory analysis of multivariate data by means of STATA Software. RESULTS: The frequencies of the dimensions of the OHIP-14 with the greatest impact were pain (13.16%) and psychological distress (14.47%). The low impact association was represented by social disability (71%) and social disadvantage (63%). The gender, type of housing, necessity and prosthesis wearing were not associated with measures of quality of life related to oral health. It was observed a good correlation between the perception (r = 0.542, p <0.001), a moderate association between higher income (r = 0.28, p <0.01) and the scores of the OHIP. CONCLUSION: It was concluded that the elderly which reported good self-perception of oral health and good income have expressed the perception that oral health reflects a good impact on quality of life. .

OBJETIVO: Analisar as condições de saúde bucal e sócio-econômicas de idosos usuários do Sistema Único de Saúde na unidade de referência Faculdade de Odontologia de Ribeirão Preto da Universidade de São Paulo, bem como sua relação com um indicador subjetivo de impactos das condições bucais na qualidade de vida.

MÉTODOS: O grupo de entrevistados foi constituído por 76 idosos mentalmente capacitados, independentes fisicamente, ambos os sexos, com 60 anos ou mais. A coleta de dados aconteceu por meio da aplicação do questionário sobre autopercepção em saúde bucal, Oral Health Impact Profile - OHIP-14 e os dados secundários obtidos dos prontuários dos pacientes atendidos na referida unidade de referência. RESULTADOS: Na amostra, 69,74% eram do gênero feminino, 59% tinham 60 a 69 anos (média de 68,5 anos). As frequências das dimensões com maior impacto foram: dor (13,16%) e desconforto psicológico (14,47%); menor impacto, incapacidade social (71%) e desvantagem social (63%). As variáveis gênero, tipo de moradia, necessidade e uso de próteses não tiveram associação com as medidas de qualidade de vida relacionada à saúde bucal. Foi observada uma boa correlação entre autopercepção e os escores do OHIP-14 (r=0.542, p<0.001) e uma associação moderada (r=0.28, p<0,01) entre maior renda e os escores do OHIP-14. CONCLUSÃO: Concluiu-se que autopercepção em saúde bucal e renda dos idosos expressaram impacto percebido de sua saúde bucal sobre a qualidade de vida. .

Dental caries in mother-child pairs from Xingu

AIM: To describe cases of dental caries in Indian mother-child pairs of the middle and lower Xingu River - Xingu Indigenous Park. METHODS: A total of 246 children aged 3-5 years old and their respective mothers took part in this study. Caries indexes dmft and DMFT were analyzed for deciduous and permanent dentitions, respectively, according to criteria proposed by the World Health Organization. RESULTS: Analysis of the DMFT index showed a mean value of 14.3 for mothers. In mothers aged between 35 and 44 years, tooth loss accounted for more than 80% of the total index score. With regard to the children, dmft index was 4.7, on average, and only 13.4% were caries-free. No significant correlation was found between mother and child caries experience (p = 0.16). CONCLUSIONS: These results suggest that it is important to consider the community as a whole, and not only the mother, regarding the oral health of indigenous children. Community should be involved in the planning of strategies for caries prevention and health promotion, taking into account the socio-cultural complexity and specificities of indigenous population and adapt them to the local reality for these strategies to become actually effective.

Dental caries associated factors in 12 year-old schoolchildren from a municipality in the state of São Paulo, Brazil / Fatores associados à cárie dentária em escolares aos 12 anos em um município do estado de São Paulo, Brasil

Objective: To analyze the possible association between dental caries, fluorosis and the need for treatment in 12 year-old schoolchildren and the socioeconomic conditions of parents/guardians in the city of Franca, in the state of São Paulo. Methods: A random sample of schoolchildren aged 12 was obtained from the school records in Franca, using a systematic random technique. The epidemiological survey was carried out by a single calibrated examiner, on 258 public and private schoolchildren in order to obtain the prevalence of dental caries, the need for treatment and the severity of dental fluorosis. Parents/guardians were also interviewed to assess their socioeconomic conditions (education and per capita income). We used multiple correlation analysis to investigate associations between category variables. Results: It was possible to identify two distinct groups, with associations between the variables: the first group, represented by schoolchildren with average prevalence of caries, need for treatment, low level of parental education and income; and a second group represented by schoolchildren with low prevalence of caries, no need for treatment, high parental education and income. The two dimensions explained approximately 35% of total inertia. The factors within each group are related. Conclusion: High income and parental education are associated with the low prevalence of dental caries but there is no association with dental fluorosis.

Objetivo: Analisar as possíveis associações entre cárie dentária, fluorose e necessidade de tratamento de escolares aos 12 anos de idade e fatores sócio-econômicos dos pais ou responsáveis, no Município de Franca, São Paulo. Métodos: Foi obtida uma amostra probabilística, através da técnica de sorteio ponderado de estabelecimentos de ensino do cadastro das escolas do município de Franca, cujos elementos amostrais foram identificados através da técnica casual sistemática. Os exames epidemiológicos foram realizados em 258 escolares de unidades de ensino público e privados, por um único examinador calibrado, para obtenção da prevalência de cárie, necessidade de tratamento e severidade da fluorose dental. Foram também realizadas entrevistas com os pais ou responsáveis para avaliação sócio econômica (escolaridade e renda familiar). Com base nesses dados foi realizada uma análise de correspondência múltipla para a busca das associações entre variáveis categóricas.

Com base nesses dados foi realizada uma análise de correspondência múltipla para a busca das associações entre variáveis categóricas. Resultados: A análise permitiu identificar dois grupos discrepantes, os quais possuem associações entre as variáveis: Grupo 1, escolares com prevalência média de cárie, baixa escolaridade dos pais, com necessidade de tratamento e baixa renda familiar; e Grupo 2, escolares com prevalência baixa de cárie, alta escolaridade dos pais, sem necessidade de tratamento e renda familiar média. As duas dimensões explicaram 35% aproximadamente da inércia total. Os fatores dentro de cada grupo estão associados. Conclusão: A escolaridade e renda alta dos pais ou responsáveis estão associadas à baixa prevalência de cárie dentária e não há associação com a fluorose dentária.

The influence of mandibular implant-retained overdentures in masticatory efficiency.

OBJECTIVE: To evaluate the masticatory efficiency of patients rehabilitated with conventional dentures (CDs) or implant-retained mandibular overdentures. BACKGROUND: Despite the evident benefits of implants on mastication as assessed by subjective patient-based outcomes, the extent of implant overdenture treatment effect on food comminution is not well established. MATERIALS AND METHODS: A randomised clinical trial was carried out with 29 completely edentulous patients divided into two groups. The first group was rehabilitated with a mandibular overdenture retained by two splinted implants with bar-clip system, while the second group was rehabilitated with a mandibular CD. Both groups also were rehabilitated with maxillary CDs. Masticatory efficiency and patient satisfaction were assessed 3 months after denture insertion. Masticatory efficiency was evaluated through the colorimetric method with the beads as the artificial test-food. Comparisons for masticatory efficiency and patient satisfaction were performed using Student's t-test (α = 0.05). RESULTS: No significant statistical difference was found for masticatory efficiency (p = 0.198). Patient overall satisfaction was significantly higher for the mandibular overdenture (p < 0.001). In addition, mandibular overdenture patients were significantly more satisfied with chewing experience (p < 0.05) and retention of the lower denture (p < 0.005). CONCLUSION: The results of this study suggest that mandibular overdenture significantly improves chewing experience, although limited effect on masticatory efficiency has been observed.

Ao encontro do Outro, a vertigem do eu: o etnopsicólogo em equipes de saúde indígena / Meeting the Other in the vertigo of the me: the ethnopsychologist in the indigenous health groups / Al encuentro del Otro el vértigo del yo: el etnopsicólogo en equipos de salud indígena

A Universidade de São Paulo, em parceria com a Universidade Federal de São Paulo e o Ministério da Saúde, idealizou o Projeto Huka-Katu, que oferece um estágio e uma disciplina aos seus estudantes do curso de graduação em Odontologia, constituídos por duas etapas (uma preparatória e uma inserção no Parque Indígena do Xingu). Com a presença de uma pesquisadora do Laboratório de Etnopsicologia (FFCLRP-USP) no projeto, surgiu uma nova parceria, com o intuito de trazer contribuições da psicanálise e da etnopsicologia. O impacto subjetivo provocado pela imersão em uma realidade cultural muito distinta pode ser bastante perturbador. Neste relato de experiência profissional, com base no que foi registrado nas reuniões e aulas supracitadas, advoga-se a conveniência da inclusão de profissionais com formação em etnopsicologia nas equipes, no intuito de preparar o odontólogo e o profissional de saúde em geral para encontros interculturais que, ao mesmo tempo em que o põem em contato com o outro, devolvem-no a um confronto consigo mesmo.

The Universidade de São Paulo, in partnership with the Universidade Federal de São Paulo and the Ministry of Health, created the project Huka-Katu, which offers a trainee program and a subject to their students of the undergraduation course in Dentistry that are systematized in two moments: one is preparatory, while the other is a inclusion in the indigenous park called Parque Indígena do Xingu. Alongside with an Ethnopsychology researcher from University of São Paulo (FFCLRP-USP) in the project, a new partnership has been established, aiming to bring contributions from the Psychoanalytical and Ethnopsychological studies. The subjective impact caused by the inclusion in a distinctly different cultural reality can be highly disturbing. In the experience record, based on the registers of the group meetings and the classes taken, it is discussed whether inclusion of Ethnopsychology professionals in groups is convenient, aiming to prepare the dentist and the health professional in general to intercultural meetings. Not only do the meetings put them in contact with the other one, but also confronted with themselves.
