Structural validity of the Brazilian version of the Sense of Coherence scale (SOC-13) in oral health research: exploratory and confirmatory factor analysis.

BACKGROUND: The Sense of Coherence (SOC) construct has been used worldwide in oral health research, but rigorous factor analyses of the scale are scarce. We aim to test the dimensional structure of the Brazilian short version of the SOC scale with 13 items. METHODS: This study is a secondary analysis of four independent cross-sectional Brazilian studies on oral health, using the 13-items SOC scale. Sample 1 was conducted on 1760 mothers and 1771 adolescents. Sample 2 comprised 1100 adults. Sample 3 had 720 adults and older individuals. Sample 4 comprised 664 adolescent students. Confirmatory Factor Analysis (CFA) was conducted on sample 1 to compare two models: 3-factor versus 1-factor. Because they were refuted, Exploratory Factor Analysis was implemented in samples 2 and 3. Modified models were tested in sample 4 using CFA. All analyses were conducted with MPlus version 7.11. RESULTS: CFA of sample 1 resulted in an unacceptable fit (RMSEA = 0.12;CFI = 0.78; TLI = 0.73; and WRMR = 3.28) for 1-factor model and 3-factor (RMSEA = 0.10; CFI = 0.87; TLI = 0.84; and WRMR = 2.50). The EFA on samples 2 and 3 showed, respectively, two eigenvalues greater than 1 (4.11 and 1.56) and (4.32 and 1.42), but the scale items soc1, soc2 and soc3 formed an uninterpretable second factor. Another CFA, using sample 4, showed acceptable model fit after removing those three items and also soc11 (RMSEA = 0.05; CFI = 0.98; TLI = 0.99; and WRMR = 0.71). CONCLUSION: The results indicate that the SOC-13 scale needs further adjustments. The one-factor model with nine items showed a good statistical fit, but the implications of excluding items should be further investigated, considering the scale's content validity, cross-cultural adaptation and theoretical background.

Sense of coherence and impact of oral health on quality of life in adults and elderly in Southern Brazil.

This cross-sectional study aimed to investigate the association between the Sense of Coherence and impact of oral health on the quality of life. Was conducted with a sample of 720 individuals of both sexes, between the ages of 50 and 74 years, selected through multistage proportional random sampling. The data collection instruments used were: short version of the Sense of Coherence Scale (SOC-13), Oral Impacts on Daily Performances (OIDP) questionnaire, oral clinical examination and questionnaire containing socio demographic and use of dental services information. Bivariate and multivariate analyses were performed through Poisson regression adjusted for robust variance, with level of significance p < 0.05. Oral impacts were reported by 416 participants (57.8%). In the adjusted model, those with strong SOC were more likely of not having any impact when compared with individuals with weak SOC (PR=1.30). Need for dental prosthesis was also associated with the outcome, individuals who did not require prosthesis had less impact (PR=1.50). The findings showed that SOC is associated with OIDP, supporting the hypothesis that individuals with strong SOC present a lower impact of oral health on the quality of life, suggesting that SOC is a determinant that can provide protection against that impact.

Resumo Este estudo transversal objetivou investigar a associação entre Senso de Coerência (SOC) e o impacto da saúde bucal na qualidade de vida. Foi realizado com uma amostra de 720 indivíduos de ambos os sexos, com idade entre 50 e 74 anos, selecionados por amostragem aleatória proporcional em múltiplos estágios. Os instrumentos de coleta de dados foram: versão curta da Sense of Coherence Scale, questionário Oral Impact on Daily Performance (OIDP), exame clínico bucal e questionário sociodemográfico e de uso de serviços odontológicos. As análises bivariadas e multivariadas foram realizadas por regressão de Poisson ajustada para variância robusta, com nível de significância p < 0,05. O impacto da saúde bucal foi relatado por 416 participantes (57,8%). No modelo ajustado, aqueles com SOC forte foram mais propensos a não ter nenhum impacto, comparados aos indivíduos com SOC fraco (PR=1,30). A necessidade de prótese dentária também foi associada ao desfecho e os indivíduos que não necessitavam prótese tiveram menor impacto (PR=1,50). Os resultados mostraram que o SOC está associado ao OIDP, apoiando a hipótese de que os indivíduos com SOC forte apresentam menor impacto da saúde bucal na qualidade de vida, sugerindo que o SOC é um determinante que pode proporcionar proteção contra esse impacto.

Factors associated with the route of birth delivery in a city in the Northeast region in the State of Rio Grande do Sul, Brazil / Fatores associados à via de parto em um município da região nordeste do Estado do Rio Grande do Sul, Brasil

Abstract Objectives: to investigate factors associated with the route of birth delivery in a hospital extending public and private healthcare services, in the Northeast region in the State of Rio Grande do Sul. Methods: a cross-sectional study with 676 postpartum women, conducted from January to May 2017. The data were collected from the hospital records and women were interviewed shortly after childbirth in the maternity. Data analysis was performed by associating the Pearson's chi-square and the Poisson regression tests with robust variance. Results: the prevalence of cesarean sections was 58.7%, that is, 41.7% in public health-care and 83.9% in private healthcare. The main reason for having a cesarean section was having had a previous one (PR=5.69; CI95%=3.64 - 8.90; p<0.001), followed by having source of childbirth financing (PR=1.54; CI95%=1.27 - 1.87; p<0.001), having source of prenatal care financing (PR=1.48; CI95%=1.22 - 1.79; p<0.001), the childbirth and prenatal care professional (PR=1.46; CI95%=1.28 - 1.66; p<0.001) and the prenatal care professional (PR=1.43; CI95%=1.07 - 1.90; p=0.016). Conclusions: the high cesarean section rates identified in this study were mainly associated with previous cesarean section. The findings suggest a change in the current childbirth care model in the city, characterized as highly medicalized, focused on the physician and on hospital care.

Resumo Objetivos: investigar os fatores associados à via de nascimento em um hospital de atendimento misto, público e privado, da região nordeste do Rio Grande do Sul. Métodos: estudo transversal com 676 puérperas realizado entre janeiro e maio de 2017. Os dados foram obtidos de registros hospitalares e entrevistas com as mulheres logo após o parto na maternidade. A análise dos dados foi realizada por intermédio do teste de associação do Qui-quadrado de Pearson e Regressão de Poisson com variância robusta. Resultados: a prevalência de cesariana foi de 58,7%, sendo 41,7% no setor público e 83,9%, no privado. Cesárea prévia foi o principal fator associado à realização de cesariana (RP=5,69; IC95%=3,64-8,90; p<0,001), seguido por fonte de financiamento do parto (RP=1,54; IC95%=1,27-1,87; p<0,001), fonte de financiamento do pré-natal (RP=1,48; IC95%=1,22-1,79; p<0,001), profissional do pré-natal e parto (RP=1,46; IC95%=1,28 - 1,66; p<0,001) e profissional do pré-natal (RP=1,43; IC95%=1,07-1,90; p=0,016). Conclusões: as elevadas taxas de cesariana identificadas neste estudo foram associadas principalmente à realização de cesárea prévia. Os achados indicam a necessidade de mudança no modelo de assistência ao parto no município, o qual é altamente medicalizado, centrado no profissional médico e na atenção hospitalar.

Abandono de la atención odontológica en programas sociales desde la perspectiva de participantes y operadores sociales: el caso Uruguay Trabaja / Abandono à assistência odontológica em programas sociais na perspectiva de participantes e especialistas sociais: o caso do Uruguay Trabaja / Dental treatment dropout in social programs from the perspective of participants and social operators: the Uruguay Trabaja case

Uruguay Trabaja (UT) es un programa socio-laboral de integración social para adultos desempleados pertenecientes a hogares en situación de vulnerabilidad socio-económica. Durante nueve meses reciben acompañamiento de expertos de Organizaciones de la Sociedad Civil (OSC) pudiendo recibir una asistencia odontológica no disponible usualmente en el Sistema de Salud del país. La tercera parte de los beneficiarios de UT inicia el tratamiento y lo abandona. El fenómeno del abandono al tratamiento odontológico fue estudiado a partir del análisis de contenido de entrevistas a participantes y expertos de las OSC. Basados en los conceptos de habitus de Bourdieu y de individualización de las protecciones de Castel, la complejidad de la vida cotidiana; ausencia de vínculo dentistas-participantes y el escaso tiempo de acompañamiento para sostener los procesos de socialización, son aspectos a considerar para comprender los abandonos de este derecho transitorio a la asistencia.(AU)

Uruguay Trabaja (UT) é um programa sociolaboral de integração social para adultos desempregados moradores de áreas em situação de vulnerabilidade socioecômica. Durante nove meses, os participantes recebem acompanhamento social de especialistas vinculados às Organizações da Sociedade Civil (OSC), podendo receber assistência odontológica, a qual não é disponibilizada rotineiramente pelo Sistema de Saúde uruguaio. Um terço dos beneficiários do UT inicia o tratamento e o abandona. O fenômeno do abandono ao tratamento odontológico foi estudado a partir da análise de conteúdo de entrevistas dos participantes do UT e especialistas das OSC. Baseados nos conceitos de habitus de Bordieu e individualização das proteções de Castel, a complexidade da vida cotidiana, ausência de vínculo dentistas-participantes e o curto tempo de acompanhamento do Programa para sustentar processos de socialização, são aspectos a serem considerados na compreensão do abandono deste direito ocasional à assistência odontológica..(AU)

Uruguay Trabaja (UT) is a socio-labor integration program for unemployed adults belonging to households in socio-economic vulnerability. During nine months they receive support from experts from Civil Society Organizations (CSO), and are entitled to comprehensive dental care not routinely provided by the Health System of Uruguay. A third of beneficiaries of UT initiate the treatment, abandoning it afterwards. The phenomenon of dropping out dental treatment was studied based on the content analysis of interviews with participants and experts from CSOs. Based on the concepts of habitus de Bourdieu and Castel's individualized protections, the complexity of everyday life; absence of dentist-participant bonding and the short time of accompaniment of UT to sustain the processes of socialization, are aspects to be considered in order to understand the abandonment of this transitory right to assistance..(AU)

Assistência odontológica em programas sociais para populações socialmente vulneráveis na perspectiva do programa Uruguay Trabaja / Dental care in social programs for socially vulnerable populations on the perspective of the Uruguay Trabaja program

Resumo Este trabalho discute características do subprograma da saúde bucal do programa Uruguai Trabaja (UT), em Montevidéu, e identifica os tratamentos odontológicos iniciados, completados e abandonados de 2008 a 2015. Por meio de análise documental, o UT é discutido a partir de dois níveis categóricos. O primeiro refere-se ao contexto macrossocial, relacionando-se à expansão da cobertura da assistência odontológica integrada nos sistemas de proteção social, enquanto o segundo se origina da observação sistemática da assistência odontológica inserida em programas de acompanhamento social. UT é um programa social anual de nove meses de duração dirigido a pessoas de 18 a 65 anos em situação de vulnerabilidade socioeconômica e desempregadas há muito tempo. Seu propósito é melhorar a empregabilidade e a integração social dos participantes. Assistência odontológica integral é um dos benefícios do programa, a qual não é disponibilizada pelo Sistema Nacional Integrado de Saúde. Dos 2.592 tratamentos odontológicos iniciados, 941 (36,3%) não chegaram ao final. Programas focalizados como o UT, enquanto dispositivos de proteção social, devem estar articulados funcionalmente a políticas sociais universais que devem responder adequadamente as necessidades da população. A saúde bucal, nesse contexto, deve ser incluída no Sistema Nacional Integrado de Saúde do Uruguai, garantindo o direito à saúde.

Abstract This paper discusses the characteristics of the oral health subprogram 'Uruguay Trabaja' (UT), in Montevideo, and identifies finished, unfinished, and abandoned dental treatments from 2008 to 2015. The implementation of the UT, its characteristics, and the subprogram aimed at oral health are described through documentary analysis. The Program is conceptually discussed according to two categorical levels. The first refers to the macro-social context, related to the expansion of dental care coverage integrated into social protection systems, while the second one is based on the systematic observation of the dental care included in social programs. The UT is a nine-month social program which occurs every year for people between 18 and 65 years old, in social and economic vulnerability situations and unemployed for a long term. It aims at improving employment chances and the participants' social integration. Comprehensive dental care is one of the benefits of the program, as it is not available at the National Integrated Health System. Of the 2.592 dental treatments initiated, 941 (36,3%) were completed. Focused programs such as the UT should be articulated to universal social policies, which must adequately meet the needs of the entire population. Comprehensive dental care should be included into the National Integrated Health System, to ensure the right to oral health.

Necessidade de tratamento ortodôntico em adolescentes do Rio Grande do Sul: relação entre autopercepção e necessidade clínica / Need for orthodontic treatment in adolescents from the state of Rio Grande do Sul, Brazil: association between self-perception and clinical need

Objetivos: analisar a associação entre a auto percepção e a necessidade clínica de tratamento ortodôntico e investigar a relação entre a necessidade de tratamento ortodôntico e o impacto nas atividades diárias comer, sorrir e falar, em adolescentes. Sujeitos e método: estudo transversal com 1.630 escolares com idade entre 15 e 19 anos, de 36 municípios do estado do Rio Grande do Sul. Os instrumentos utilizados para determinar a necessidade de tratamento ortodôntico foram o Índice de Estética Dental (DAI) e o Componente Estético (AC) do Índice de Necessidade de Tratamento Ortodôntico (IOTN). Os dados foram analisados com o programa SPSS 21.0, utilizando-se os testes Qui-Quadrado de Pearson ou Qui-Quadrado de tendência linear e a regressão de Poisson. O nível de significância adotado foi de 5%. Resultados: observou-se associação positiva entre o IOTN e o DAI. A proporção de sujeitos que perceberam a necessidade de tratamento ortodôntico aumentou com a recomendação feita pelo dentista. Entretanto, a maioria dos adolescentes entrevistados não percebia necessidade de tratamento ortodôntico. Após o ajuste, observou-se associação entre a maloclusão e o desempenho da atividade diária sorrir (RP = 2,03) e o sexo dos escolares (RP = 1,28). Também se observou associação entre o sexo dos adolescentes (RP = 1,23), a escolaridade do pai (RP = 1,21) e o impacto na atividade comer. A atividade diária de falar estava associada com a escolaridade do pai (RP = 2,11). Conclusão: existe associação entre a auto percepção de tratamento ortodôntico e a necessidade clínica. A maloclusão impacta a atividade sorrir entre os adolescentes, entretanto, o mesmo não ocorre com as atividades comer e falar. (AU)

Objective: to analyze the association between self- -perception and clinical need for orthodontic treatment, and to investigate the relationship between the need for orthodontic treatment and the impact on daily activities of eating, smiling, and speaking, in adolescents. Subjects and method: cross-sectional study with 1630 school children aged 15 through 19 years from 36 cities of the state of Rio Grande do Sul, Brazil. The instruments used to determine the need for orthodontic treatment were the Dental Aesthetic Index (DAI) and the Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN). The data were analyzed with the SPSS 21.0 software using Pearson's chi-square or linear trend chi-square tests and Poisson regression. The significance level was 5%. Results: there was a positive association between IOTN and DAI. The proportion of subjects who perceived the need for orthodontic treatment increased with the recommendation from the dentist. However, most of the adolescents interviewed did not perceive the need for orthodontic treatment. After adjustment, there was an association of malocclusion with the performance of the daily activity of smiling (PR = 2.03) and the gender of school children (PR = 1.28). An association was also observed for the gender of adolescents (PR = 1.23) and paternal level of education (PR = 1.21) with the daily activity of eating. The daily activity of speaking was associated with the paternal level of education (PR = 2.11). Conclusion: there is an association between self-perception of orthodontic treatment and the clinical need. Malocclusion affects the activity of smiling among adolescents, but the same does not occur with the activities of eating and speaking. (AU)

Dental pain, use of dental services and oral health-related quality of life in southern Brazil.

This study aimed at assessing the relationship between dental pain and the reason for using dental services and oral health quality of life in people aged 50 to 74 years in southern Brazil. A cross-sectional population-based study was conducted with 720 individuals aged 50 to 74 years, living in three health districts in the city of Porto Alegre. Dental impacts on daily life and sociodemographic data were assessed using structured interviews. The Oral Impacts on Daily Performance - OIDP instrument was used to measure oral impacts. The information was analyzed by Poisson regression with robust variance adjustment, taking into account cluster sampling. Dental pain was present in 32.5% of those reporting an oral impact on their daily activities. Dental pain most frequently affected talking (37.6%), cleaning teeth and gums (37.0%) and enjoying the companionship of people (36.5%). After adjustments to the multivariate analysis, the reason for dental visits due to dental pain was found to have a high impact on daily activities [RP 1.68 (1.11 - 2.54].

[Impact of oral health teams of the Family Health Strategy on the oral health of adolescents in the south of Brazil]. / Impacto das equipes de saúde bucal da Estratégia da Saúde da Família na saúde bucal de adolescentes do sul do Brasil.

The Family Health Strategy (FHS) has produced effective results in health indicators. In this cross-sectional study, the impact of the oral health teams (OHT) of the Family Health Strategy was evaluated on the oral health of 2581 adolescent schoolchildren aged 12 and 15-19 years in 36 municipalities (19 with and 17 without OHT/FHS). Four dentists performed oral examinations. Socioeconomic status, the use of and access to health services were assessed via a structured questionnaire. The presence of the OHT in the FHS were the main independent variables. Outcomes were Decayed, Missing, Filled Teeth (DMFT) and its components, toothache, gingival bleeding, and dental calculus. The data were analyzed by means of negative binomial and Poisson regression. Multilevel analysis was conducted to adjust the outcomes to OHT/FHS and individual variables. In the unadjusted model there was no association between the OHT in the FHS and the outcomes analyzed. After adjustment, young people in areas not covered by the OHT/FHS had almost half of the tooth loss of adolescents from the areas covered (RM = 0.64 CI 95%, 0.43 to 0.94).

Relationship between Sense of Coherence and oral health in adults and elderly Brazilians.

The purpose of this study was to investigate the relationship between Sense of Coherence (SOC) and oral health clinical variables (number of teeth present and absence of need for dental prostheses). The sample consisted of 720 adults and elderly Brazilians. The data were collected at home using the SOC-13 scale - a form of clinical examination for the evaluation of oral conditions - and a questionnaire evaluating socioeconomic aspects and the use of dental services. Statistical analysis, both univariate and multivariate, was performed by Poisson regression with robust variance adjustment. The average age of the participants was 60.2 years, and they were predominantly female (57.8%). Among the participants who had a strong SOC, the absence of the need for dental prostheses was 34% higher than among those with a weak SOC, demonstrating a significant difference between the groups (PR = 1.34, 95%CI = 1.06-1.70; p = 0.015). Individuals who had a strong SOC had a 5% higher prevalence of 14 or more existing teeth than those with a weak SOC, which was statistically significant after adjustment for co-factors (PR = 1.05, 95%CI = 1.01-1.11, p = 0.033). A strong personal Sense of Coherence has a beneficial influence on the oral health of adults and older people in Brazil.

Impacto das equipes de saúde bucal da Estratégia da Saúde da Família na saúde bucal de adolescentes do sul do Brasil / Impact of oral health teams of the Family Health Strategy on the oral health of adolescents in the south of Brazil

Resumo A Estratégia da Saúde da Família (ESF) tem demostrado resultados efetivos em indicadores de saúde. Neste estudo transversal foi avaliado o impacto das equipes de saúde bucal (ESB) da ESF na saúde bucal de 2581 adolescentes escolares, com idade de 12 e 15-19 anos de 36 municípios, 19 com e 17 sem ESB/ESF. Quatro dentistas realizaram exames bucais. Situação socioeconômica, uso e acesso aos serviços de saúde foram coletados em questionário estruturado. Presença das ESB na ESF foi a principal variável independente. Os desfechos foram CPOD e seus componentes, dor de dente, sangramento gengival e cálculo dentário. Os dados foram analisados pelas médias das regressões binomiais negativas e Poisson. O efeito da ESB/ESF e de variáveis individuais foi ajustado em modelo multinível. No modelo bruto não houve associação das ESB na ESF com nenhum dos desfechos analisados. Após o ajuste, jovens de áreas não cobertas pela ESB/ESF tiveram quase a metade da perda de dentes dos adolescentes das áreas cobertas (RM = 0,64 IC95%; 0,43-0,94).

Factor analysis of two versions of the Oral Impacts on Daily Performance scale.

The aim of this study was to explore the factorial structure and agreement of two scoring versions of the Oral Impacts on Daily Performance (OIDP) scale, and to compare the fit of the originally proposed factorial structure, as opposed to an alternative model. Exploratory factor analyses (EFA) were conducted to explore the dimensional structure of the OIDP on a convenience sample of 200 adults (S1). Confirmatory factor analyses (CFA) were performed on a random sample of 720 adults (S2). The Cronbach's alpha coefficients for the total and frequency versions of the OIDP scale were, respectively, 0.81 and 0.70 for S1, and 0.82 and 0.79 for S2, with a quadratic Kappa κ = 0.83 (95% CI: 0.75-0.89) in S1 and κ = 0.92 (95% CI: 0.89-0.94) in S2. Exploratory factor analyses showed one factor for the total version and three factors (non-interpretable) for the frequency version. Confirmatory factor analyses showed that the frequency version for the one-factor model (Model 1) had the best fit [Root Mean Square Error of Approximation (RMSEA) = 0.04; Comparative Fit Index (CFI) = 0.98; Tucker-Lewis index (TLI) = 0.97, χ(2) P-value < 0.01]. The one-factor model was not significantly different from the original three-factor model. These findings suggest that the scale captures only one overall quality of life dimension, and that the frequency version was the most parsimonious model of the OIDP scale.

Sense of Coherence and Toothache of Adolescents from Southern Brazil.

AIMS: To investigate the association in adolescents between toothache and sense of coherence (SOC), a psychosocial construct defined as a global orientation to life. METHODS: A school-based cross-sectional study was carried out in 36 municipalities comprising up to 50,000 residents in southern Brazil. The target population was adolescents from 15 to 19 years of age. The sample consisted of 1,150 adolescents chosen by systematic sampling; the final adjusted analysis by Poisson regression included 1,065 individuals. Data were collected using a questionnaire, SOC scale, and the Decayed Missing Filled Teeth (DMFT) index. RESULTS: Of the adolescents in the sample, 29.8% reported experiencing toothache in the previous 6 months. The prevalence of dental caries was 31.0%, and the DMFT index was 3.22. SOC was a significant protective factor for toothache; the prevalence ratio was 0.65 (95% confidence interval [CI] = 0.55-0.75). Girls presented 39% more toothaches than boys (95% CI = 1.15-1.68). Individuals who saw the dentist for reasons other than reviews or check-ups had a toothache prevalence that was 85% higher than their counterparts (95% CI = 1.47-2.34). Adolescents with tooth decay reported up to two times more toothache than those without tooth decay. CONCLUSION: The results of this study showed that a strong SOC protected against toothache. A health-promotion approach may lead to better patterns of oral health.

Correlations between two different methods to score bleeding and the relationship with plaque in systemically healthy young adults.

AIM: To evaluate the correlation between bleeding on marginal probing (BOMP) and bleeding on pocket probing (BOPP), and the correlation of both bleeding indices with plaque. MATERIALS AND METHODS: This cross-sectional study screened 336 participants, from which 268 were eligible for examination and analysis. Bleeding and plaque indices were assessed by single examiners, at six sites per tooth. RESULTS: The mean percentage of sites per individual with bleeding on marginal probing, bleeding on pocket probing and dental plaque were 19.9%, 51.2% and 32.2% respectively. In the quadrants where the margin was probed before the pocket, a 4.6 percentage points higher bleeding tendency with BOPP was observed (p < 0.05). At a site level, the correlation coefficients of plaque and bleeding on marginal probing and bleeding on pocket probing were 0.19 and 0.20 respectively. Both bleeding indices were also shown to be correlated (r = 0.89, fixed effect model). CONCLUSION: The prevalence of bleeding upon probing is influenced by the scoring method that is used for the diagnosis. Probing the bottom of the pocket results in significantly more bleeding than running a probe along the margin.

Adapting and testing the oral impacts on daily performances among adults and elderly in Brazil.

OBJECTIVES: To cross-culturally adapt and evaluate the psychometric properties of the oral impact on daily performance (OIDP) in Brazilians aged 50-74 years; to test the impact of oral health on 'work' and 'vigorous physical activity'. BACKGROUND: Clinical oral health indicators do not assess the perceived impact of oral health on people's lives. METHODS: The study was performed through small group interviews, pilot studies and a main study with 200 people aged 50 and over. Data were collected through interviews in health centres. RESULTS: For content validity, 'eating' (1.00, p < 0.001) and 'speaking' (0.96, p < 0.001) obtained the highest level of agreement among experts. For criterion and construct validity, there was an inverse correlation between self-rated oral health, perceived oral treatment needs and satisfaction with oral health and OIDP score. Cronbach's alpha coefficient varied from 0.69 to 0.67 when 'work' and 'vigorous physical activities' were deleted. Test-retest reliability was 0.69 (ICC). CONCLUSION: The validation process showed that the Brazilian OIDP has the necessary basic psychometric properties to be used in the 50-74 years age group in Brazil. 'Work' and 'vigorous physical activities' had low impact on oral health. The activity 'vigorous physical activities' was not maintained in the instrument because of its low impact, while 'work' was maintained due of the increase in the 50-59 years age group in the Brazilian population.

Elementary Schoolteachers' Knowledge and Decision-making Regarding Dental Trauma.

PURPOSE: To evaluate elementary schoolteachers' knowledge and decision making regarding dental trauma in Porto Alegre, Brazil. MATERIALS AND METHODS: A questionnaire-based survey was conducted among elementary schoolteachers (n=442). Questions encompassed sociodemographic characteristics and decision making regarding dental trauma. Data on the appropriate answer regarding what to do with a traumatised or avulsed tooth were analysed with multiple logistic regressions, adjusting for age, gender, work experience and previous training. RESULTS: The study population consisted largely of women (90%), was 40 to 49 years old (44.3%) and had more than 15 years of work experience (56.6%). Women (OR=2.68/p=0.041), teachers under 30 years old (OR=4.95/p=0.041), those with more than 15 years of work experience (OR=8.95/p<0.001) or those who had already received previous dental trauma instructions (OR=1.95/ p=0.119) were more likely to choose the appropriate answer for an avulsion situation. Teachers under 30 years old (OR=2.88/ p=0.279), those with more than 15 years of work experience (OR=4.55/p=0.001) or those who had received previous training (OR=3.39/p=0.009) presented higher probabilites of choosing the appropriate answer for a crown fracture event. CONCLUSION: Greater work experience or previous instructions on how to approach dental trauma in the school environment were found to be major factors in schoolteachers' decision making regarding dental trauma.

Tecnologias de informação e comunicação na educação da Odontologia: estudo transversal de uma população do sul do Brasil / Information and Communication Technologies in dental education: cross-sectional study of a population of southern Brazil

O objetivo do presente estudo foi avaliar as competências em relação às Tecnologias de Informação e Comunicação (TICs) de estudantes de Odontologia. Um estudo transversal foi realizado com os estudantes de Odontologia da Universidade Federal do Rio Grande do Sul, Brasil. Os dados foram coletados através de um questionário previamente validado pelo Centro de Ciências de Saúde Oral da Universidade de Malmö e submetido ao processo de adaptação transcultural para o português. Os resultados foram transformados em escores conforme literatura prévia e categorizados para as comparações. Análise descritiva, qui-quadrado e teste exato de Fischer foram utilizados. O escore de competência em relação às TICs foi considerado muito bom e apresentou relação com o nível de escolaridade materno. Já o escore de importância das TICs foi mediano e relacionado à idade. Concluiu-se que os estudantes de Odontologia apresentaram bom domínio das ferramentas de TICs e nível moderado em relação à importância atribuída ao uso odontológico dessas tecnologias (AU).

The purpose of the present study was to evaluate the competence of the students to use technologies in dental educational. A cross-sectional study was done with dental students of a university of the south of Brazil. It was used a questionnaire previously validated by the Center Oral Health Sciences of University of Malmö (Sweden) and adapted to Portuguese. The collected data were transformed into scores based on Mattheos et al. (2005). For analysis purposes, scores and sociodemographic variables were categorized. The descriptive analyses was realized, Chi Square and Exact Fischer`s tests were used to test the association between the sociodemographic data and the scores regarding the Information and Communication Technologies (ICT). The mean competence score was considered very good and associated with education level of the mothers. The mean importance score was regular and associated with age. It was concluded that the students of a university of south of Brazil had a very good level regarding the competence of the use of ICT even though moderate level in relation to the importance was given to dental use of these technologies (AU).

Redução da cárie dentária em adolescentes: distribuição temporal e espacial em 36 municípios do Sul do Brasil 2003 e 2011 / Dental caries reduction among adolescents: temporal and spatial distribution in 36 Southern Brazilian municipalities, 2003 and 2011 / Reducción de la caries dental en adolescentes: distribución espacial y temporal en 36 municipios del Sur de Brasil 2003 y 2011

Objetivo: descrever a experiência de cárie dentária em adolescentes e sua distribuição espacial-temporal. Métodos: estudo ecológico com 4.205 (2003) e 3.531 (2011) escolares de 12 e 15-19 anos de idade, respectivamente, em 36 municípios do Rio Grande do Sul, em cujas macrorregiões de saúde foram georreferenciados os indicadores de média de dentes cariados, perdidos e obturados (CPOD), prevalência de livres de cárie (CPOD=0) e de cárie não tratada. Resultados: em 2003 e 2011, respectivamente, as médias de CPOD foram de 3,63 e 1,66 (12 anos) e de 7,43 e 3,43 (15-19 anos); aumentaram os adolescentes livres de cárie, de 18,6 para 42,1 por cento (12 anos) e de 7,5 para 22,2 por cento (15-19 anos); reduziu-se a cárie não tratada, de 50,9 para 27,2 por cento (12 anos) e de 56,1 para 32,4 por cento (15-19 anos), diferentemente entre municípios e macrorregiões. Conclusão: no período, diminuiu a experiência de cárie, permanecendo a distribuição desigual entre municípios e macrorregiões.

Objective: to evaluate dental caries in adolescents and its spatial and temporal distribution in southern Brazilian municipalities. Methods: an ecological study was conducted with 4,205 (2003) and 3,531 (2011) students aged 12 and 15-19 in 36 cities in Rio Grande do Sul where macro-regional indicators of the average number of decayed, missing and filled teeth (DMFT), untreated caries prevalence and the percentage of caries-free teeth (DMFT = 0) were georeferenced. Results: in 2003 and 2011, respectively, mean DMFT was 3.63 and 1.66 (12 years) and 7.43 and 3.43 (15-19 years). Caries-free adolescents increased from 18.6 percent to 42.1 percent (12 years) and from 7.5 percent to 22.2 percent (15-19 years); untreated caries decreased from 50.9 percent to 27.2 percent (12 years) and from 56.1 percent to 32.4 percent (15-19). Results varied between municipalities and macro-regions. Conclusion: dental caries reduced after 8 years, with uneven distribution between macro-regions and municipalities.
