Exclusive breastfeeding intention among pregnant women and associated variables: a cross-sectional study in a Brazilian community / Intenção de amamentar entre gestantes e variáveis associadas: estudo transversal em uma comunidade brasileira

ABSTRACT Objective: To investigate exclusive breastfeeding (EBF) intention and associated variables among women in the third trimester of pregnancy. Methods: The data were collected with a questionnaire for the pregnant women (n=653), from December/2018 to November/2019. They answered the Infant Feeding Intentions (IFI) scale, translated and adapted to Brazilian Portuguese, and a questionnaire on sociodemographic, biological, family, pregnancy, breastfeeding, health care, and habits variables. Descriptive statistics and multiple logistic regression analyses were performed with a 5% significance level, following a multilevel hierarchical model that estimated the association between the dependent and independent variables. The outcome EBF intention measured by the IFI score was dichotomized by the median (<16 or =16). Results: Mean±standard deviation score for the IFI scale was 14.4±2.6 (score 0: very strong intention to not breastfeed at all; score 16: very strong EBF intention up to six months). The results from the regression analysis showed that pregnant women who had no intention to bottle feed (OR=4.33; 95%CI 2.79-6.72) or did not know (OR=1.85; 95%CI 1.21-2.82), those who planned the pregnancy (OR=1.52; 95%CI 1.09-2.12), those who believed they would have help to care for the baby (OR=3.60; 95%CI 1.51-8.56) or did not know (OR=3.97; 95%CI 1.26-12.51), and those who reported knowing the World Health Organization recommendations on breastfeeding (OR=1.73; 95%CI 1.13-2.64) were more likely to show a very strong EBF intention. Conclusions: Pregnant women in the third trimester of pregnancy presented a strong EBF intention. The higher EBF intention score was significantly associated with the structural, setting, and individual determinants.

RESUMO Objetivo: Investigar a intenção materna de amamentar exclusivamente (IMA) e variáveis associadas entre as mulheres no terceiro trimestre de gravidez. Métodos: A coleta de dados foi realizada por meio de entrevista e questionário semiestruturado e autoadministrado, entre dezembro/2018 e novembro/2019. As gestantes (n=653) responderam à escala Infant Feeding Intentions (IFI) testada, traduzida e adaptada para o português do Brasil e ao questionário contendo perguntas sobre variáveis sociodemográficas, biológicas e familiares, bem como relacionadas à gestação, ao aleitamento materno, à assistência à saúde e a hábitos. Foram realizadas análises estatísticas descritivas e de regressão logística múltipla hierarquizada, com nível de significância de 5%, para estimar a associação entre as variáveis independentes e o desfecho. A IMA, medida pela escala IFI, foi dicotomizada pela mediana (<16 ou =16). Resultados: A pontuação média±desvio padrão para a escala IFI foi de 14,4±2,6. Os resultados da análise de regressão mostraram que as gestantes que não tinham intenção de oferecer mamadeira (OR=4,33; IC95% 2,79-6,72) ou não sabiam (OR=1,85; IC95% 1,21-2,82), que planejaram a gestação (OR=1,52; IC95% 1,09-2,12), aquelas que acreditavam que teriam ajuda nos cuidados com o bebê (OR=3,60; IC95% 1,51-8,56) ou que não sabiam (OR=3,97; IC95% 1,26-12,51), bem como aquelas que relataram conhecer as recomendações da Organização Mundial de Saúde sobre amamentação (OR=1,73; IC95% 1.13-2.64) tinham mais chances de mostrar uma IMA muito forte. Conclusões: As gestantes no terceiro trimestre de gestação apresentaram forte IMA. A maior IMA esteve significativamente associada aos determinantes estruturais, contextuais e individuais.

Age and Type of Delivery as Risk Indicators for Maternal Mortality / Idade e tipo de parto como indicadores de risco para mortalidade materna

Abstract Objective: This study assessed maternal mortality (MM) and related factors in a large-sized municipality in the Southeastern region of Brazil (Campinas, São Paulo) during the period 2000-2015. Methods: This study consisted of two phases: 1. An analytical nested case-control phase that assessed the impact of individual and contextual variables on MM; and 2. an ecological phase designed to contextualize maternal deaths by means of spatial analysis. The case group consisted of all maternal deaths (n = 87) and the control group consisted of 348 women who gave birth during the same period. Data analysis included descriptive statistics, association, and multiple logistic regression (MLR) tests at p < 0.05 as well as spatial analysis. Results: Maternal Mortality Ratio was 37 deaths per 100.000 live births. Deaths were dispersed throughout the urban territory and no formation of cluster was observed. MLR showed that pregnant women aged > 35 years old (OR = 2.63) or those with cesarean delivery (OR = 2.51) were more prone to maternal death. Conclusion: Maternal deaths were distributed dispersedly among the different socioeconomic levels and more prone to occur among older women or those undergoing cesarean deliveries.

Resumo Objetivo: Esse estudo avaliou a mortalidade materna (MM) e fatores relacionados em um município de grande porte da região sudeste do Brasil (Campinas, São Paulo) no período de 2000-2015. Métodos: Esse estudo consistiu de duas fases: 1. Uma fase analítica de caso-controle que avaliou o impacto de variáveis individuais e contextuais na MM; 2. Uma fase ecológica delineada para contextualizar as mortes maternas por meio de análise espacial. O grupo caso consistiu de 87 mortes maternas e o grupo controle de 348 mulheres que tiveram bebês durante o mesmo período. Os dados foram analisados por estatística descritiva, testes de associação e regressão logística múltipla (RLM) (p < 0,05) assim como análise espacial. Resultados: A taxa de mortalidade materna foi de 37 mortes para cada 100.000 nascidos vivos. As mortes foram dispersas por todo o território urbano e não se observou formação de clusters. Na RLM observou-se que mulheres grávidas com idade > 35 anos (OR = 2,63) ou aquelas que passaram por cesárea (OR = 2,51) foram mais propensas à morte materna. Conclusão: As mortes maternas foram distribuídas dispersamente entre os diferentes níveis socioeconômicos e mais propensas a ocorrer entre mulheres > 35 anos de idade ou que passaram por cesárea.

Association between Pacifier Use, Bottle-Feeding, and Pre-Postnatal Variables: A Cohort Study

ABSTRACT Objective: To determine the prevalence and analyze the variables associated with the use of pacifiers and/or bottles by infants up to 6 months of age. Material and Methods: Data on sociodemographic characteristics, intention to offer pacifier and bottle-feeding, pregnancy and breastfeeding (BF) variables were collected at baseline by interviews and a self-administered questionnaire among pregnant women in the 3rd trimester. After delivery, mother-baby binomials were followed by phone calls at the 1st, 3rd, and 6th months of the baby's life (n=467) to gather information on the type of delivery, baby's gender, BF in the first hour of the newborn's life, baby's weight, mother's return to work, and oral habits. Association analyses were performed using logistic regression models with a 5% significance level with the pacifier/bottle-feeding use as the outcome. Results: Most mothers (52.5%) reported their babies used bottle-feeding, 48.2% used pacifiers and 33.4% used both of them throughout the 6 months. Intention to offer pacifier and bottle-feeding was reported by 45.0% and 54.8% of the mothers at the 3rd trimester of the pregnancy, respectively. Not living in one's own residence (OR=1.53; 95%CI: 1.05-2.24) and having the prenatal intention of offering a pacifier (OR=2.50; 95%CI: 1.63-3.83) to the baby were significantly associated with pacifier use. Variables significantly associated with bottle-feeding were mother's return to work (OR=2.48; 95%CI: 1.54-3.97), baby's lower birth weight (OR=1.58; IC95%: 1.07-2.33), and prenatal intention to offer bottle-feeding (OR=2.51; 95%CI 1.56-4.04). Conclusion: About half of the babies used pacifiers or were bottle-fed, which were associated with the mother's prenatal intention to offer them to their babies and socioeconomic factors.

Evidence-practice gap in treatment recommendations for proximal caries among Brazilian dentists / Lacuna entre a evidência e a prática nas recomendações de tratamento para cárie proximal entre dentistas brasileiros

ABSTRACT Little is known about how Brazilian dentists' treatment decisions for proximal carious lesions are compared to current evidence-based recommendations, so better understanding is needed to close any potential evidence-practice gap. Objectives: This cross-sectional study aimed to quantify the evidence-practice gap about proximal carious lesions treatment and identify dentist factors associated with this evidence-practice gap. Methods: Brazilian dentists (n=214) from Araraquara, São Paulo State, "completed a questionnaire about their dentist and practice characteristics and a translated version of the "Assessment of Caries Diagnosis and Caries Treatment" from the U.S. National Dental Practice-Based Research Network. Five radiographic images of proximal carious lesions in low-risk and high-risk patient scenarios were used. Associations between treatment recommendations and lesion, dentist, and practice characteristics were tested for statistical significance (p<0.05). Results: Lesions confined to the enamel would be restored by 35% and 71% of dentists in the low-risk and high-risk patient scenarios, respectively, suggesting a substantial evidence-practice gap given that surgical intervention of enamel lesions is not consistent with current evidence. The lesion depth threshold to recommend a permanent restoration differed between the low-risk and high-risk patient scenarios (p<0.001). Specific dentist/practice characteristics (dentist gender, graduate of a public dental school, postgraduate training, use of caries risk assessment) were significantly associated with the evidence-practice gap, but the magnitude of these differences was not major Conclusion: A substantial evidence-practice gap in treatment of proximal carious lesions was found for the sample overall, even when clinical scenarios presented low-risk patients. Global strategies are needed to close this substantial evidence-practice gap.

RESUMO Pouco se sabe se as decisões de tratamento dos dentistas brasileiros para lesões cariosas proximais são comparadas às recomendações atuais baseadas em evidências, portanto, é necessário um melhor entendimento para fechar qualquer potencial lacuna entre a evidência e a prática. Purpose: Este estudo transversal teve como objetivo quantificar a lacuna entre a evidência e a prática na decisão de tratamento das lesões cariosas proximais e identificar os fatores associados a essa lacuna entre a evidência e a prática. Methods: Cirurgiões-dentistas brasileiros (n=214) de Araraquara, Estado de São Paulo, preencheram um questionário sobre suas características odontológicas e clínicas e uma versão traduzida do "Assessment of Caries Diagnosis and Caries Treatment" da U.S. National Dental Practice-Based Research Network. Cinco imagens radiográficas de lesões cariosas proximais em cenários de pacientes de baixo risco e alto risco foram usadas. Associações entre recomendações de tratamento e lesão, dentista e características da prática foram testadas (p<0,05). Results: As lesões confinadas ao esmalte seriam restauradas por 35% e 71% dos dentistas nos cenários de pacientes de baixo risco e alto risco, respectivamente, sugerindo uma lacuna entre a evidência e a prática substancial, dado que a intervenção cirúrgica das lesões do esmalte não é consistente com as evidências atuais. O limiar de profundidade da lesão para recomendar uma restauração permanente diferiu entre os cenários de pacientes de baixo risco e alto risco (p<0,001). Características específicas do dentista/prática (sexo do dentista, graduado em uma faculdade pública, pós-graduação, uso da avaliação de risco de cárie) foram significativamente associadas à lacuna entre a evidência e a prática, mas a magnitude dessas diferenças não foi importante. Conclusions: uma lacuna entre a evidência e a prática substancial na decisão de tratamento de lesões cariosas proximais foi encontrada para a amostra como um todo, mesmo quando os cenários clínicos apresentavam pacientes de baixo risco. Estratégias globais são necessárias para fechar essa lacuna entre a evidência e a prática.

Evidence-practice gap in treatment decisions about defective composite and amalgam restorations among Brazilian dentists

Better understanding of dentists' decision-making about defective restorations is needed to close the evidence-practice gap (EPG). This study aimed to quantify the EPG about defective restorations and identify dentist factors associated with this EPG. Methods: 216 dentists from São Paulo State, Brazil, completed a questionnaire about three clinical case scenarios involving defective composite restorations with cementum-dentin margins (case 1) and enamel margins (case 2), and an amalgam (case 3) restoration. Dentists were asked what treatment, if any, they would recommend, including preventive treatment, polishing, re-surfacing, or repairing the restoration, or replacing the entire restoration. Replacing the entire restoration in any of these three scenarios was classified as inconsistent with the evidence, comprising an EPG. Bivariate analyses using Chi-square, ANOVA, or multiple comparison tests were performed (p<.05). Results: for defective composite restorations, 49% and 55% of dentists chose to replace the entire restoration for cases 1 and 2, respectively. Twenty-nine percent of dentists chose to replace the entire amalgam restoration. Dentists were significantly more likely to choose to replace the defective amalgam restoration than the composite restoration with a defect at the cementum-dentin margins or the enamel margins (both at p < .001). Female dentists were more likely to choose a conservative treatment than male dentists for cases 1 (p=.034) and 2 (p=.009). Dentists with a higher percentage of patients interested in individualized caries prevention were also more conservative in case 1 (p=.045). Conclusion: a substantial EPG regarding treatment decisions for defective restorations exists, especially for composite restorations. This study adds to the international evidence that an EPG exists in this clinical area and that global strategies need to be developed to close the gap

Dental trauma and oral health-related quality of life among 7th-grade students of public elementary schools

Dental trauma is a public health problem because of its high prevalence rates and treatment costs and for affecting mainly younger individuals. Aim: This cross-sectional study aimed to investigate the variables associated with dental trauma and its influence on oral health-related quality of life among 7th-grade students of public elementary schools. Methods: The data was collected with semi-structured and self-administered questionnaires and an intraoral clinical examination (n = 204). The variables collected regarded dental trauma, lip coverage, overjet, oral health-related quality of life (Child Perceptions Questionnaire - CPQ11-14 ISF: 8), and sociodemographic profile. Association tests and the Mann-Whitney test were performed at a 5% significance level. Results: Dental trauma occurred in 12.3% of students, 94.6% had adequate lip coverage, and the mean overjet was 2.7 mm (±2.0). Sex was the only variable with a statistically significant association with dental trauma (p = 0.021). There was no statistically significant difference in the CPQ11-14 ISF: 8 score between students with and without dental trauma (p = 0.136). Conclusions: Dental trauma was significantly associated with sex and did not impact the oral health-related quality of life of the students

Caries risk assessment in dental practices by dentists from a Brazilian community

Abstract Data on dental practices related to caries risk assessment (CRA) are scarce among Brazilian dentists. This study aimed to determine the prevalence of CRA use by dentists and factors associated with its use, as well as to quantify dentists' ratings of the importance of specific factors when treatment planning. Dentists registered at the Regional Council of Dentistry of São Paulo State - Araraquara region were sent two paper questionnaires that comprised: a) characteristics of dentists themselves, their practices, and their patients; and b) the translated version of the "Assessment of Caries Diagnosis and Caries Treatment" Questionnaire from the U.S. National Dental Practice-Based Research Network. Participants were 206 dentists who currently practiced in Araraquara and treated dental caries. Descriptive statistics and multiple logistic regression analyses were used for data analysis. Thirty-six percent of the dentists reported they perform CRA and, among them, 36% indicated they record the assessment on a special form that is kept in the patient chart. More years since dental school graduation (OR = 1.1, p = 0.002) and holding an advanced academic degree (OR=2.6, p=0.005) were associated with a higher likelihood of performing CRA, whereas exclusively using a private practice model (OR = 0.5, p = 0.016) was associated with a lower likelihood of performing CRA. The current oral hygiene and commitment to return for follow-up were the most important risk factors for treatment planning. In conclusion, CRA was not a routine procedure in daily practice among the majority of participating dentists. Specific demographic, practice and academic education characteristics were associated with performing CRA.

Methods for Caries Prevention in Children Reported by Dentists from a Brazilian Community

ABSTRACT Objective: To describe the dental practice patterns related to caries prevention in children aged 6-18 years and associated factors. Material and Methods: Dentists (n=162) from Araraquara, Brazil, completed two paper questionnaires: (1) one about characteristics of their practice and their patient population; and (2) a translated version of the "Assessment of Caries Diagnosis and Caries Treatment" Questionnaire from the National Dental Practice-Based Research Network. Regression analyses were used for data analysis (p<0.05). Results: Dentists reported using in-office fluoride (IOF) and dental sealants (DS) in 74.2% and 45.1% of their pediatric patients, respectively. Regression analysis showed that female dentists (p=0.035 for DS; p=0.044 for IOF; p=0.011 for non-prescription fluoride rinse), those with advanced degrees (p=0.032 for prescription of fluoride), those who graduated from a private dental school (p=0.018 for chlorhexidine rinse), those who provided caries prevention regimens (p<0.001 for DS; p=0.004 for IOF; p=0.013 for non-prescription fluoride rinse), those with a greater percentage of patients interested in a caries prevention regimen (p=0.007 for non-prescription fluoride rinse), those working in a private practice model (p=0.047 for prescription of fluoride) were more likely to recommend some type of preventive methods to their pediatric patients. Conclusion: Dentists reported recommending IOF to most of their pediatric patients. Certain dentists', practices', and patients' characteristics were associated to some caries prevention regimens recommended by dentists.

Methods for caries prevention in adults among dentists from a brazilian community

Little is known about dental practice patterns of caries prevention in adults among Brazilian dentists. Aim: To quantify procedures used for caries prevention for adult patients among dentists from a Brazilian community. Methods: Dentists (n=197) who reported that at least 10% of their patients are more than 18 years old participated in the first Brazilian study that used a translated version of the "Assessment of Caries Diagnosis and Caries Treatment" from the U.S. National Dental Practice-Based Research Network. A questionnaire about characteristics of their practice and patient population were also completed by the dentists. Generalized linear regression models and a hierarchal clustering procedure were used (p<0.05). Results: In-office fluoride application was the preventive method most often reported. The main predictors for recommending some preventive agent were: female dentist (dental sealant; in-office fluoride; non-prescription fluoride) and percentage of patients interested in caries prevention (dental sealant; in-office fluoride; non-prescription fluoride). Other predictors included private practice (dental sealant), percentage of patients 65 years or older (in-office fluoride), graduation from a private dental school (non-prescription fluoride), years since dental school graduation (chlorhexidine rinse) and using a preventive method (recommending sealant/fluoride/chlorhexidine rinse/sugarless, xylitol gum). Cluster analysis showed that dentists in the largest subgroup seldom used any of the preventive agents. Conclusion: Dentists most often reported in-office fluoride as a method for caries prevention in adults. Some practitioner, practice and patients' characteristics were positively associated with more-frequent use of a preventive agent

Influence of caries risk on the retention of a resin-modified glass ionomer used as occlusal sealant: a clinical trial / Influência do risco de cárie na retenção de um ionômero de vidro modificado por resina usado como selante oclusal: ensaio clínico

Introduction: Little is known whether caries risk influence occlusal sealants retention. Objective: To determine the retention rates (RR) of the resin-modified glass ionomer cement used as occlusal sealant in permanent first molars of 6-8-year old schoolchildren and to analyze the influence of caries risk at baseline on the RR of the sealant, over a 24-month period. Material and method: The sealant application was performed in a dental office at the beginning of the study, after children being allocated into high caries risk group (HR) and low caries risk group (LR). The examinations were performed by the same calibrated dentist at 0, 6, 12, 18 and 24 months. Retention rates were estimated, the Kaplan-Meier method was used to estimate the survival probabilities; and the comparison between HR and LR groups was evaluated by Wilcoxon and log-rank test. Result: The results showed that 14% of sealed teeth showed total loss (16% for HR and 12% for LR) and 46% showed partial loss during the study (51% for HR and 41% for LR), in relation to the baseline sample. No difference could be demonstrated by the survival analysis between HR and LR groups (p>0.05). Conclusion: Caries risk did not influence the retention rates of a resin-modified glass ionomer cement used as occlusal sealant in 6-8-year old schoolchildren.

Introdução: Pouco se sabe sobre a influência do risco de cárie na retenção de selantes oclusais. Objetivo: Avaliar as taxas de retenção de um cimento de ionômero de vidro modificado por resina utilizado como selante oclusal em primeiros molares permanentes de escolares de 6-8 anos, e analisar a influência do risco de cárie na taxa de retenção do selante, durante um período de 24 meses. Material e método: A aplicação do selante foi realizada em consultório odontológico no início do estudo, após as crianças serem alocados no grupo de alto risco (AR) ou baixo risco (BR) de cárie. Os exames foram realizados pelo mesmo dentista calibrado em 0, 6, 12, 18 e 24 meses. As taxas de retenção foram estimadas e o método de Kaplan-Meier foi utilizado para estimar as probabilidades de sobrevivência. A comparação entre os grupos AR e BR foi avaliada pelos testes de Wilcoxon e log-rank. Resultado: Os resultados mostraram que 14% dos dentes selados apresentaram perda total (16% para AR e 12% para BR) e 46% apresentaram perda parcial durante o estudo (51% de AR e 41% para BR), em relação a amostra no início do estudo. Nenhuma diferença pode ser demonstrada pela análise de sobrevivência entre os grupos AR e BR (p> 0,05). Conclusão: O risco de cárie não influenciou as taxas de retenção de um cimento de ionômero de vidro modificado por resina usado como selante oclusal em escolares de 6-8 anos de idade.

Após uma semana, 17 CDs preencheram o questionário novamente para avaliar a reprodutibilidade pelo teste de correlação intra-classe. Resultados: A etapa de tradução mostrou que os termos/sentenças traduzidos de forma destoante pelos diferentes pesquisadores eram, na verdade, sinônimos, e indicaram que o processo de tradução foi facilmente realizado. Em relação à compreensão do questionário, 95% (n=20) dos CDs não mostraram dúvida/dificuldade ao preenchê-lo. Os dados de reprodutibilidade mostraram que 42% (n=22) das questões apresentaram correlação satisfatória e 58% (n=31) correlação excelente. Conclusão: Conclui-se que o processo de tradução e adaptação cultural do questionário foi realizado de forma satisfatória e que a versão brasileira do questionário foi facilmente compreendida pela população estudada.(AU)

Aim: The aim of this study was to translate and cross-culturally adapt the "Assessment of Caries Diagnosis and Caries Treatment" questionnaire from the Dental Practice Based Research Network (DPBRN) into Brazilian Portuguese. Methods: The questionnaire on dental practices related to diagnosis, prevention, treatment, and caries risk assessment underwent translation and cross-cultural adaptation following pre-established criteria: initial translation, back-translation, and committee review. During the pre-test, the questionnaire was filled out by 21 dentists in order to evaluate mistakes, to find deviations in the translations, and to identify the comprehension of the questions. After one week, 17 dentists filled out the questionnaires again to evaluate their reliability by means of the intra-class correlation test. Results: The translation process showed that the term/sentences translated differently by distinct researchers were synonyms and indicated that the process was easily performed. Regarding the comprehension of the questionnaire, 95% (n=20) of the dentists showed no doubts / difficulty when filling it out. Reliability data showed that 42% (n=22) of the questions showed a satisfactory correlation, while 58% (n=31) showed an excellent correlation. Conclusion: In conclusion, the translation and cross-cultural adaptation process of the questionnaire was performed satisfactorily, and the Brazilian version of the questionnaire was easily understood by the studied population.(AU)

Estudo comparativo de indicadores de saúde bucal em município do estado de São Paulo / Comparative study of oral health indicators in primary care of a São Paulo State's city

Comparar indicadores de saúde bucal (Rendimento, Atrição, Ênfase em Prevenção Modificado, Relação Restauração/Extração) e Relação 1ª Consulta/Urgência entre 15 Unidades de Saúde da Família e 11 Unidades Básicas de Saúde de município do interior paulista, de 2008 a 2011. Os dados foram coletados a partir do Sistema de Informações Ambulatoriais do SUS (SIA-SUS) e comparados os modelos de atenção por meio de série histórica, teste não paramétrico (Mann-Whitney) e estatística descritiva. Embora haja o processo de fortalecimento da Estratégia Saúde da Família o modelo assistencial representado pelas Unidades Básica de Saúde se mostra mais efetivo em alguns aspectos da saúde bucal no serviço público.

To compare four oral health indicators (Income, Attrition, Modified Prevention Emphasis, Restoration/Extraction) and the 1st Consultation/Urgency Relationship in 15 Family Health Units and 11 Basic Health Units, in an interior city of São Paulo State, 2008-2011. The data were collected from SIA-SUS and the indicators compared through historical series using the non-parametric test (Mann Whitney) and descriptive statistics. Although there is a strengthening process of the Family Health Strategy, the care model represented by the Basic Health Units still proves more effective in some aspects of oral health in public service.

Preval?ncia e severidade da dor orofacial em gestantes / Prevalence and severity of orofacial pain in pregnant women

Objective: To evaluate the prevalence and severity of oral pain in pregnant women. Methods: A cross-sectional study was conducted on a sample of pregnant women who were receiving dental care at a Dental School. A structured questionnaire about self-perception of oral conditions and the presence and severity of orofacial pain in the mouth or teeth in the last 6months was applied. Results: 80 pregnant women participated in the study and, of these, 58.8% reported having a problem with their teeth, 31.3% periodontal problems, 61.3% bad taste in mouth and 62.5% bad breath. Only 22.5% of pregnant women did not exhibit any form of oral pain. The most frequently reported pains were: pain with hot/cold liquids or sweets (56.2%) and spontaneous toothache (38.8%). With regard to severity, mild and moderate pain were the most frequently reported, but there was a group of 23.8% of pregnant women with severe or very severe pain caused by hot or cold liquids and 18.8% in the same condition in relation to spontaneous pain. Conclusion: The results of this study showed that, despite the high prevalence of pain detected in the pregnant women, severity was low and referred to specific situations.

Análise de custo-efetividade de métodos preventivos para superfície oclusal de acordo com o risco de cárie: resultados de um ensaio clínico controlado / Cost-effectiveness analysis of preventive methods for occlusal surface according to caries risk: results of a controlled clinical trial / Análisis del coste-efectividad de los métodos preventivos para una superficie oclusal según el riesgo de caries: resultados de un ensayo clínico controlado

Este estudo apresenta o resultado de uma avaliação de custo-efetividade conduzida ao longo de um ensaio clínico controlado para avaliar a efetividade do selamento com ionômero de vidro modificado por resina (Vitremer, 3M ESPE) e da aplicação de verniz fluoretado (Duraphat, Col-gate) em superfícies oclusais de primeiros molares permanentes, em crianças de 6 a 8 anos (N = 268), segundo o risco de cárie (alto risco; baixo risco). As crianças foram examinadas semestralmente, ao longo de 24 meses, pelo mesmo dentista calibrado, após alocação em seis grupos: controle alto risco e baixo risco (educação em saúde bucal trimestral); verniz alto risco e baixo risco (educação em saúde bucal trimestral + aplicação semestral de verniz); e selante alto risco e baixo risco (educação em saúde bucal trimestral + única aplicação do selante). A análise mostrou que o selamento de primeiros molares permanentes em crianças de alto risco apresentou razão de C/E de R$ 225,21(US$ 119,80) por superfície oclusal salva, e razão incremental de C/E de R$ 203,71(US$ 108,36) por superfície oclusal adicional salva. Conclui-se que uma única aplicação de selante, em escolares de alto risco, foi a intervenção mais custo-efetiva.

This study presents the results of a cost-effectiveness analysis in a controlled clinical trial on the effectiveness of a modified glass ionomer resin sealant ( Vitremer, 3M ESPE) and the application of fluoride varnish (Duraphat, Colgate) on occlusal surfaces of first permanent molars in children 6-8 years of age (N = 268), according to caries risk (high versus low). Children were examined semiannually by the same calibrated dentist for 24 months after allocation in six groups: high and low risk controls (oral health education every three months); high and low risk with varnish (oral health education every three months + varnish biannually); and high and low risk with sealant (oral health education every three months + a single application of sealant). Economic analysis showed that sealing permanent first molars of high-risk schoolchildren showed a C/E ratio of US$ 119.80 per saved occlusal surface and an incremental C/E ratio of US$ 108.36 per additional saved occlusal surface. The study concluded that sealing permanent first molars of high-risk schoolchildren was the most cost-effective intervention.

En este estudio se presentan los resultados de una evaluación de costo-efectividad (C/E) durante un ensayo clínico controlado para evaluar la efectividad de la obturación con ionómero de vidrio modificado con resina (Vitremer, 3M ESPE) y la aplicación de barniz de flúor (Duraphat, Colgate) en las superficies oclusales de los primeros molares permanentes, para niños de 6-8 años (N = 268) de edad, de acuerdo con el riesgo de caries (alto riesgo-bajo riesgo). Los niños fueron examinados cada seis meses por el mismo dentista calibrado, durante 24 meses, después de haberle sido asignados seis grupos: control alto riesgo y bajo riesgo (educación de salud bucal cada tres meses); barniz alto riesgo y bajo riesgo (educación de salud bucal cada tres meses + barniz semestralmente); obturación alto riesgo y bajo riesgo (educación de salud bucal cada tres meses + una sola aplicación de ionómero de vidrio). El análisis económico mostró que la obturación de los primeros molares permanentes de escolares de alto riesgo presenta una relación C/E de US$ 119.80 de ahorro por superficie oclusal y una ratio C/E incremental de US$ 108.36 de ahorro adicional por superficie oclusal.

Impacto dos problemas de saúde bucal na qualidade de vida de gestantes / Impact of oral health problems on the quality of life of pregnant women

Objetivos: 1) Avaliar o impacto dos problemas de saúde bucal na qualidade de vida de gestantes por meio do questionário OHIP-14, bem como a presença de cárie dentária, doença periodontal e uso e necessidades de próteses em gestantes; 2) associar as variáveis sociodemográficas e condições de saúde bucal encontradas no exame clínico com o OHIP-14. Métodos: Além da aplicação do questionário OHIP-14, realizou-se uma avaliação clínica das condições bucais (índices: IPC, CPO-D e avaliação protética) em 51 gestantes que procuraram atendimento odontológico junto à Clínica de Odontologia Preventiva, no período de abril de 2008 a agosto de 2010. Realizaram-se análises descritivas para caracterização da amostra, análise bivariada (teste de Qui-Quadrado ou Exato de Fisher) e regressão logística múltipla em nível de significância de 5% para analisar a associação entre o impacto da saúde bucal na qualidade de vida de gestantes e as variáveis sociodemográficas e clínicas. Resultados: Os dados do OHIP-14 mostraram menor impacto da saúde bucal na qualidade de vida. O CPOD médio foi 12,8; 70,6% das gestantes apresentavam cálculo dental e 58,8% necessitavam de prótese. A associação entre OHIP-14 e última visita ao dentista e CPOD permaneceram no modelo final de regressão (p<0,05). Conclusão: A experiência de cárie das gestantes examinadas foi considerada alta, a maioria apresentava necessidade de prótese e presença de cálculo dental. O OHIP apresentou baixo impacto no grupo estudado e foi significativamente influenciado pela última visita ao dentista e pelo índice CPOD...

Objectives: 1) to evaluate the impact of oral health problems on the quality of life of pregnant women by the simplified Oral Health Impact Profile (OHIP-14) questionnaire as well by the presence of dental caries, periodontal disease and denture use/need; 2) to correlate the sociodemographic variables and the oral health conditions revealed in the clinical examinations with the OHIP-14. Method: In addition to the application of the OHIP-14 questionnaire, clinical examination of the oral conditions (CPI - community periodontal index, DMFT and prosthetic evaluation) was performed on 51 pregnant women, who sought dental treatment between April 2008 and August 2010 at the Preventive Dentistry Clinic. Descriptive analyses were made for sample characterization, bivariate analysis (chi-square or FisherÆs exact tests) and multiple logistic regressions at a 5% significance level to assess the correlation between the impact of oral health on the quality of life of pregnant women and the socio-demographic and clinical variables. Results: The OHIP-14 data showed a lesser impact of oral health on the womenÆs quality of life. The mean DMFT was 12.8; 70.6% of the pregnant women presented dental calculus and 58.8% needed prostheses. The association between OHIP-14 data and last dental visit and DMFT remained in the final regression model (p<0.05). Conclusion: Caries experience of the pregnant women was considered high. Most of them needed prostheses and presented dental calculus. The OHIP-14 presented a low impact on this population and was significantly influenced by the last dental visit and the DMFT index...

Tamanho de amostra e estimativa de custo em levantamento epidemiológico de cárie dentária / Sample size and costs estimate in epidemiological survey of dental caries

O objetivo do presente estudo foi analisar como a prevalência e a distribuição da cárie dentária influenciam o tamanho da amostra em levantamentos epidemiológicos, e os custos para sua realização. Foram utilizados dados de levantamentos realizados em escolares de 12 anos em Bauru nos anos de 1976, 1984, 1990, 1994 e 2001, e em Piracicaba nos anos de 2001 e 2005. Os tamanhos amostrais foram dimensionados considerando-se a média e o desvio padrão obtidos, fixando-se erro amostral em 1 por cento, 2 por cento, 5 por cento e 10 por cento. Os custos foram estimados considerando material permanente, de consumo e recursos humanos. Verificou-se aumento no tamanho das amostras em ambos os municípios, variando de 119 em 1976 para 1.118 em 2001 em Bauru, e de 954 em 2001 para 1.252 em 2005 em Piracicaba, considerando-se um erro amostral de 10 por cento. Considerando-se diferentes erros amostrais, verificou-se o custo para o levantamento, sendo que o mesmo depende do quanto o pesquisador se permite errar em relação ao verdadeiro valor da média da população. Conclui-se que a diminuição da prevalência da cárie dentária determinou o aumento no tamanho das amostras e a elevação dos custos para realização dos levantamentos.

This study aimed to analyze how the prevalence and the distribution of dental caries influence the sample size in epidemiological surveys, and how much are the costs. Secondary data of oral health surveys in 12-year-old schoolchildren from Bauru in 1976, 1984, 1990, 1994, and 2001, and from Piracicaba in 2001 and 2005 were studied. Sample sizes were estimated taking into account the mean DMFT and standard deviation of each survey, establishing sampling errors of 1 percent, 2 percent, 5 percent, and 10 percent. Costs were estimated considering permanent material, consumption material and human resources. The sample size in both towns needed to be increased, ranging from 119 in 1976 to 1,118 in 2001 in Bauru, and from 954 in 2001 to 1,252 in 2005 in Piracicaba, when a sampling error of 10 percent was considered. The cost of dental caries surveys was verified considering different sampling errors. This cost depends on how acceptable is the margin of difference between the true mean and the one found in the survey. In conclusion, the reduction in the prevalence of dental caries has determined the need for increase in sample size and in costs for conducting the surveys.

Use of occlusal sealant in a community program and caries incidence in high- and low-risk children

OBJECTIVE: The aims of this study were to investigate the effectiveness of sealant placement under the guidelines of the Oral Health Promotion Program for Children and Adolescents (Portugal), and to test the influence of clinical and socioeconomic variables on the DMFT increment in 277 children, born in 1997. MATERIAL AND METHODS: A dental hygienist performed the initial examinations and sealant placement (Helioseal, Vivadent) on the permanent first molars in 2005. These activities were registered in dental records that were assessed in 2007. Children were classified according to caries risk at baseline [high (HR: DMFT+dmft>0); low (LR: DMFT+dmft=0) risk] and sealant placement as follows: HR-S and LR-S Groups (with sealant placement); HR-NS and LR-NS Groups (without sealant placement). A calibrated dentist performed the final examination in 2007 at school, based on the World Health Organization recommendations. The variables collected were: dental caries, visible dental plaque, malocclusions, and socioeconomic level (questionnaire sent to children's parents). For univariate (Chi-square or Fisher tests) and multivariate (Multiple logistic regression) analyses the DMFT increment >0 was selected as dependent variable. RESULTS: Approximately 17.0 percent of the children showed DMFT increment>0 (mean=0.25). High-risk children presented a significant increase in the number of decayed and/or filled teeth. These children had 7.94 more chance of developing caries. Children who did not receive sealant were 1.8 more prone to have DMFT increment >0. CONCLUSION: It appears that sealant placement was effective in preventing dental caries development. Moreover, the variables "risk" and "sealant placement" were predictors for DMFT increment in the studied children.

Conhecimento de mães sobre promoção de saúde bucal em bebês / Mother’s knowledge on oral health promotion for babies

Objetivo: O objetivo deste estudo foi avaliar o nível de conhecimento sobre promoção de saúde bucal em bebês de todas as mães (n=60), com idade de 18-42 anos, que frequentaram a Clínica de Prevenção da Faculdade de Odontologia de Araraquara, da Universidade Estadual Paulista (FOA-Unesp), durante o período 2005-2008. Métodos - Realizou-se uma entrevista utilizando questionário contendo 18 questões abertas e cinco fechadas sobre o conhecimento e práticas em saúde bucal de bebês relacionadas à cárie e sua prevenção, bem como sobre informações sociodemográficas. Resultados - A maioria das mães acreditava que o leite materno não causa cárie (73,3%), que esta não é uma doença transmissível (51,6%) e que o antibiótico provoca cárie (63,3%). Quase todas as mães (93,3%) responderam que a doença poderia ser evitada escovando os dentes, ação que deveria ser iniciada desde o nascimento do primeiro “dente de leite” (75%). Para 73,3% das entrevistadas,o uso do fio dental deveria ser iniciado somente após o irrompimento de todos os “dentes de leite”. A maior porcentagem das mães (83,3%) sabia o que era o flúor, mas 33,3% desconheciam a época ideal para iniciar sua utilização. A orientação do cirurgião-dentista em relação à saúde bucal deseus bebês foi considerada importante por 96,7% das mães. Conclusões - As mães entrevistadas demonstraram conhecimento em relação à escovação dental em bebês, porém, não sabiam sobre outras variáveis importantes na promoção de saúde bucal dos bebês, como os fatores etiológicos da doença, uso de compostos fluoretados e visitas ao cirurgião-dentista.

Objective: The aim of this study was to assess the knowledge level on oral health promotion for babies of all mothers (n=60), aged 18-42 years, assisted in the Preventive Dentistry Clinic of the Faculty of Dentistry of Araraquara, at Universidade Estadual Paulista (UNESP), during the period 2005-2008. Methods -An interview was performed using a questionnaire with 18 open and five closed questions about knowledge and practices related to caries prevention as well as demographic information. Methods -The majority believed that breast milk does not cause caries (73.3%), that caries is not a transmissible disease (51.6%) and that antibiotics cause caries (63.3%). Almost all mothers (93.3%) responded that brushing teeth could prevent the disease, action that should be initiated since first tooth erupts (75%). For 73.3% of the respondents, the use of dental floss should be initiated only after all deciduous teeth erupt. Results - The majority (83.3%) knew what was fluoride, but a third of them (33.3%) did not know the best time to start using it. The dentist counseling related to oral health of babies was considered important by 96.7% of mothers. Conclusion - The mothers presented good knowledge about baby’s oral hygiene, however, they did not know about other important variables for oral health promotion of babies.

Extensão universitária e trabalho voluntário na formação do acadêmico em odontologia / University extension and volunteer work in the education of undergraduate dental students

Este estudo destacou a importância da vivência do acadêmico em odontologia em atividades extramuros e experiências de trabalho voluntário para a aquisição de conhecimentos e habilidades importantesna futura prática profissional. Foi realizada uma revisão bibliográfica nas bases de dados Medline, Scielo eLilacs, selecionando os artigos relacionados às atividades de extensão e voluntariado desempenhadas pelosalunos de odontologia. A extensão universitária e o serviço voluntário ainda encontram dificuldades, dentrodos cursos de Odontologia, para se estabelecerem como práticas importantes para a formação do aluno.Entretanto, o mercado de trabalho atual exige um profissional com conhecimentos tanto da técnica quantodas características socioculturais da comunidade no desenvolvimento de sua prática odontológica, uma vezque o ser humano necessita ser compreendido nos seus aspectos biopsicosociais para ser tratado de formaintegral. Desta forma, os cursos de Odontologia deveriam prestigiar de forma igualitária na formação doaluno, tanto as habilidades reabilitadoras como as de promoção de saúde, adquiridas, em grande parte, ematividades extra-murais, de maneira a resgatar a formação integral do profissional da saúde. Além disso,o acadêmico deve estar atento às oportunidades oferecidas nestes aspectos durante a graduação, já que aodontologia está se tornando mais competitiva, e o cirurgião-dentista que resume sua vida profissional apenasao seu consultório, perde a chance de fazer-se conhecer e atuar em outros espaços sociais.

Autopercepção e condições de saúde bucal em gestantes / Self-perception and oral health status in pregnant women

O estudo avaliou indicadores de saúde bucal em gestantes por meio da determinação da prevalência de cárie dentária, periodontopatias, uso e necessidade de próteses; identificou a autopercepção de condições de saúde bucal e avaliou a associação entre as variávies. Exame clínico foi realizado em 50 gestantes atendidas na Clínica de Odontologia Preventiva e Sanitária da FOAr-UNESP utilizando indicadores tradicionais de saúde: IPC, CPO-D e avaliação protética. Um questionário semi-estruturado foi aplicado para identificar a percepção sobre a saúde bucal e coletar variáveis sóciodemográficas. Para análise, três grupos foram formados segundo a percepção de saúde bucal: boa, regular, ruim, e comparados segundo as variáveis clínicas, pelos testes Kruskal-Wallis e Dunn. O CPO-D das gestantes foi considerado alto; todas apresentaram alterações periodontais; a maioria não utilizava e não necessitava de nenhum tipo de prótese; 36% das gestantes consideraram boa sua aparência bucal. Houve diferença significativa entre os grupos para o índice CPOD e para necessidade de prótese. Embora a experiência de cárie tenha sido alta, a necessidade de prótese ter sido detectada na maior parte da amostra e a presença de cálculo dental tenha sido observada em todas as voluntárias, a maioria considerou sua condição bucal satisfatória.

This study evaluated oral health indicators by determining the prevalence of dental caries, periodontal diseases, prosthetic conditions and need in pregnant women; identified self-perceived oral health status and evaluated association between variables. A clinical examination was performed in fifty pregnant women assisted in the Preventive Dentistry Clinic-FOAr-UNESP using traditional oral health indicators: DMFT, Community Periodontal Index (CPI) and prosthetic conditions. A semi-structured questionnaire was applied to identify oral health perception and to collect sociodemographic variables. For data analysis, pregnant women were allocated in three groups according to their oral health perception (good, fair, poor) and compared according to clinical variables by the Kruskal-Wallis and Dunn tests. DMFT was high, all of them showed periodontal changes, most do not use and do not require any type of prosthesis; 36% considered their oral appearance as good. There was significant difference between groups for the DMFT index and prosthetic need. It may be concluded that despite dental caries experience of pregnant women was found to be high, the prosthetic need have been detected in most of them and the presence of calculus was observed in all the volunteers, the majority considered their oral health status satisfactory.
