Prenatal, neonatal and postnatal factors and the developmental defects of dental enamel / Fatores pré-natais, neonatais e pós-natais e defeitos de desenvolvimento do esmalte dentário

ABSTRACT Objective: To estimate the prevalence of developmental defects in dental enamel and its possible association with prenatal, neonatal and postnatal conditions in six-year-old schoolchildren in a southern Brazilian municipality. Methods: A cross-sectional study was conducted involving 655 six-year-old schoolchildren. Sociodemographic and health data were collected through interviews with mothers and children's oral examinations at schools. Multivariate analyses were performed using Poisson regression with robust estimator. Results: The prevalence of developmental defects of enamel was 44.0%. Demarcated opacities were the most prevalent, followed by diffuse opacities. Late pregnancy, maternal schooling less than eight years, female gender and child's white skin color were independently associated with the prevalence of demarcated opacities. Conclusions: The prevalence of developmental defects in dental enamel was 44.0%. Late pregnancy, maternal schooling less than eight years, female gender and child's white skin color were associated with the prevalences.

First Thousand Days of Child Life and the Development of Risk Factors for Malocclusions

ABSTRACT Objective: To identify the association between individual and socioeconomic factors during the first thousand days of the child's life and the occurrence of risk behaviors for the development of malocclusions. Material and Methods: Cross-sectional study. A sample of 655 6-year-old schoolchildren and families was included. Interviews with mothers were performed at home. The dependent variables were risk behaviors to the development of malocclusions. Independent variables were socioeconomic conditions, aspects of gestation, birth and health of the child up to two years of age. Bivariate and multivariate analyzes were performed through Poisson regression. Results: Maternal education of less than eight years was independently associated with the interruption of exclusive breastfeeding until the fourth month (PR=1.58 CI 95%; 1.07; 2.37). Occupation of the mother with income [PR=1.26; 1.02; 1.56)], occupation of the father without income [PR=1.46 (1.01; 2.14)] were associated fwith interruption of breastfeeding until the sixth month. Pregnancy in adolescence [PR=0.83 (0.70; 0.98)] and nursery attendance [PR=1.15 (1.02; 1.28)] were associated with bottle use. Nursery attendance [PR=1.27 (1.01; 1.59)], hospitalization in the first 29 days of life [PR=1.34 (1.01; 1.80)], occurrence of reflux [PR=1.30 (1.01; 1.70)] were associated with pacifier using. Conclusion: Variables related to the period of the first thousand days of life are associated with higher risk behaviors for the occurrence of malocclusions.

Protocolos de atendimento odontológico em UTI Covid / Dental care protocols in Covid

O presente estudo aborda os protocolos odontológicos instituídos na Unidade de Terapia Intensiva COVID de um Hospital do Extremo Sul Catarinense. A cavidade oral, considerada uma abertura para a entrada de microrganismos, possui características favoráveis ao seu crescimento, com temperatura e umidade ideais para sua sobrevivência em longo prazo. A odontologia, por manipular diretamente mucosa oral, fica exposta e vulnerável ao contágio do COVID-19, assim como a equipe multiprofissional que manipula o paciente nas diversas áreas de atenção à saúde, no ambiente hospitalar. A COVID-19 é uma infecção respiratória aguda causada pelo coronavírus SARS-CoV-2, potencialmente grave, de elevada transmissibilidade e de distribuição global. A maioria das pessoas (cerca de 80%) se recupera da doença sem precisar de tratamento hospitalar. Uma em cada seis pessoas infectadas por COVID-19 fica gravemente doente e desenvolve dificuldade de respirar. As pessoas idosas e as que têm outras condições de saúde, como pressão alta, problemas cardíacos e do pulmão, diabetes ou câncer, têm maior risco de ficarem gravemente doentes. No entanto, qualquer pessoa pode pegar a COVID-19 e ficar gravemente doente. Constatou-se que a aplicação de protocolos odontológicos na Unidade de Terapia Intensiva apresenta uma série de vantagens em relação à prevenção da contaminação dos profissionais de saúde, à manutenção da saúde bucal do paciente, aos benefícios gerais para a saúde, à prevenção e ao tratamento de infecções oportunistas, que podem reduzir o tempo de internação do paciente, pois infecção generalizada e pneumonia são doenças nosocomiais também causadas por distúrbios na microbiota oral. Os resultados mostraram que não há cirurgiões dentistas atuando na Unidade de Terapia Intensiva, os protocolos não são específicos para área de odontologia e os equipamentos de proteção individuais são utilizados, porém, não em todos atendimentos(AU)

The present study addresses the dental protocols established in the COVID Intensive Care Unit of a Hospital in Extremo Sul Santa Catarina. The oral cavity, considered an opening for the entry of microorganisms, has characteristics favorable to its growth, with ideal temperature and humidity for its long-term survival. Dentistry, by directly manipulating the oral mucosa, is exposed and vulnerable to COVID-19 contagion, as well as the multidisciplinary team that handles the patient in the different areas of health care, in the hospital environment. COVID-19 is a potentially serious acute respiratory infection caused by the SARS-CoV-2 coronavirus, with high transmissibility and global distribution. Most people (about 80%) recover from the disease without needing hospital treatment. One in six people infected with COVID-19 becomes seriously ill and develops difficulty breathing. Elderly people and those with other health conditions, such as high blood pressure, heart and lung problems, diabetes or cancer, are at increased risk of becoming seriously ill. However, anyone can take COVID-19 and become seriously ill. It was found that the application of dental protocols in the Intensive Care Unit has a number of advantages in relation to the prevention of contamination of health professionals, the maintenance of the patient's oral health, the general benefits for health, prevention and treatment of opportunistic infections, which can reduce the patient's hospital stay, as generalized infection and pneumonia are nosocomial diseases also caused by disorders in the oral microbiota. The results showed that there are no dentists working in the Intensive Care Unit, the protocols are not specific to the field of dentistry and individual protective equipment is used, however, not in all cases(AU)

Prevalence and Associated Factors of Dental Trauma in Six-Year-Old School-Children

ABSTRACT Objective: To estimate the prevalence and associated factors of dental trauma in 6-year-old school children in the city of Palhoça, Brazil. Material and Methods: Cross-sectional study nested in a cohort study. It involved a representative sample of school children born in 2009, residing in the municipality and regularly enrolled in public and private schools (n = 1,102). Clinical data were obtained through oral exams. To evaluate the incisal overjet, the distance in millimeters was measured horizontally from the labial surface of the lower central incisor to the labial surface of the upper incisor. Bivariate analyses were performed using the Chi-square test, with a p-value <0.05 considered statistically significant. Multivariate analyses using Poisson Regression were performed to identify independent associations between the prevalence and the independent variables studied. Results: Prevalence of dental trauma was 4.2% (95% CI 3.0-5.4). Dental trauma was statistically associated with studying in a private school (PR = 1.03; 95% CI 1.01-1.06) (p=0.016) and with inadequate lip coverage (PR = 1.08; 95% CI 1.01-1.14) (p=0.016). Conclusion: The prevalence of 4.2% of dental trauma in six-year-old children, associated with inadequate and greater lip coverage in children from private schools should be taken into account, since most teeth at this stage are newly erupted.

The Influence of the First Thousand Days of Life on Establishing Determinant Behaviors for Dental Caries in Childhood

ABSTRACT Objective: To study the influence of the first thousand days of life on establishing determinant behaviors for dental caries in childhood. Material and Methods: Longitudinal retrospective study involving 664 children born in 2009 living in a southern Brazilian municipality was carried out. Data was collected through interviews with mothers and through child's health card. Dependent variables were 1) tooth brushing onset after two years of age; 2) absent tooth brushing or once a day; 3) tooth brushing without adult supervision; 4) not having gone to the dentist until the age of 6; and 5) seek for dental services due to toothache at 6 years of age, over the last 30 days. Bivariate and multivariate analyses were performed using Poisson Regression to estimate relative risks (RR) and respective confidence intervals at the 95% accuracy level. Results: Mothers with lower schooling at child's birth presented a higher risk of "child's tooth brushing onset only after two years of age", "brushing the teeth once a day only or not brushing" and with "child not having gone to the dentist until the age of 6". Mothers who did not have a job when the child was born were associated with "not having gone to the dentist until the age 6". Children with gastroesophageal reflux who underwent hospitalization for more than 2 days under age 2 were associated with "seeking dental services because of pain at 6 years of age over the last 30 days". Conclusion: Higher risks of some determinant behaviors related to dental caries were associated with variables of the period of the first thousand days of life.

Dental trauma and oral health-related quality of life in schoolchildren from public schools of a southern Brazilian city / Trauma dental e o impacto na qualidade de vida de escolares da rede pública em uma cidade no sul do Brasil

ABSTRACT Objective: To study the impact of dental trauma on the oral health-related quality of life among Brazilian students. Methods: A cross-sectional study involving a representative sample of students of the public schools (n = 435) in a city in southern Brazil was carried out. Data on dental trauma were collected through oral examinations using the O'Brien's criteria (1993) restricted to fractures and avulsions. The Brazilian version of the Oral Impacts on Daily Performances (OIDP) was used in order to collect data on the impact of oral health-related quality of life. Bivariate and multivariate analysis were performed through Poisson log-linear regression with robust estimator with significance levels set at p <0.05. Prevalence ratios (PR) and confidence intervals (95%) were estimated. Results: The prevalence of dental trauma was 7.2%, and it was associated with the following dimensions: performing daily activities [(PR = 3.52 (95% CI, 1.06-11.75)] (p = 0.040), and speaking [(PR = 3.67 (95% CI, 1.24-10.86)] (p = 0.019) after adjusting for sex, age, dental caries and malocclusion. Conclusion: The prevalence of dental trauma found among this population was low, but significantly associated with oral health-related quality of life.

RESUMO Objetivo: Estudar o impacto do trauma dental na qualidade de vida relacionada a saúde oral entre escolares brasileiros. Métodos: Foi realizado estudo transversal envolvendo uma amostra representativa de escolares (n = 435), em uma cidade no sul do Brasil. Os dados sobre trauma dental foram coletados através de exames orais utilizando os critérios do O'Brien (1993), restritas a fraturas dentais e avulsões. A versão brasileira dos impactos no desempenho diário (OIDP) foi utilizado para recolher dados sobre o impacto na qualidade de vida relacionada à saúde bucal. O teste do qui-quadrado foi utilizado para a análise bivariada com níveis de significância de p <0,05. As razões de prevalência (RP) e intervalos de confiança (95%) foram estimados utilizando regressão de Poisson log-linear com um estimador robusto. Resultados: A prevalência de trauma dental foi de 7,2%, e foi associado com as seguintes dimensões: realização de atividades cotidianas [(RP = 3,52 (IC 95%, 1,06-11,75)] (p = 0,040), e falar [(PR = (IC 95%, 1,24-10,86) 3,67] (p = 0,019) após o ajuste para sexo, idade, cárie dentária e maloclusão. Conclusão: A prevalência de traumatismo dentário encontrado entre esta população era baixa, mas significativamente associada à qualidade relacionada à saúde bucal de vida.

Cross-Cultural Adaptation and Validation of the COHIP-SF19 to be used in Brazil

Objective: To carry out a cross-cultural adaptation and validation of the Child Oral Health Impact Profile - COHIP-SF 19 to be used in Brazil. Material and Methods: The adaptation process followed five stages: translation into Portuguese, synthesis of different translations, back-translation, expert panel analysis, and pre-final version testing. The final version was administered at two different moments to a sample of 100 schoolchildren aged 8-15 years in Criciúma, Brazil. The Brazilian version of the Child Perceptions Questionnaire (CPQ11-14) was administered as a comparison parameter. In both administrations of the questionnaire, factor analysis, principal component extraction, and factor rotation were performed. The internal validation was performed by using the α-Cronbach coefficient and the congruence coefficient between the rotated factors in the two administrations of the questionnaire. In order to analyze the external validity, the factors of the first administration of COHIP-SF 19 and CPQ11-14 factors were compared by using simple linear regression analysis and congruence coefficient. Results: A Brazilian version of the questionnaire was obtained. The results of the internal validity analysis indicated adequate internal consistency and statistically significant internal congruence in the two factors identified in the factorial analysis. The linear regression analysis between the COHIP-SF 19 and CPQ11-14 showed weak correlations, and the congruence indices were not statistically significant. Conclusion: The Brazilian version of COHIP-SF 19 showed good internal consistency, but lacked external validity when compared to CPQ11-14.

Autoestima e cárie dentária em adolescentes: um estudo seccional / Self-esteem and dental caries in adolescents: a cross sectional study

Introdução: A cárie dentária na adolescência continua sendo um importante problema de saúde pública; entretanto, a sua relação com os fatores psicológicos é pouco estudada. Objetivo: Estudar a possível associação entre aspectos de autoestima e cárie dentária em adolescentes. Material e método: Estudo transversal envolvendo amostra de 409 adolescentes de 13 municípios do sul do Brasil. A cárie foi avaliada segundo critérios da Organização Mundial da Saúde e a autoestima, pela Escala de Rosenberg. O teste do qui-quadrado foi utilizado para determinar a significância estatística das associações. Para ajustar para variáveis de confusão, foi utilizada a regressão loglinear de Poisson com estimativa robusta. Resultado: Foram observadas associações positivas entre presença de dentes cariados e alguns aspectos da escala de autoestima: Às vezes, eu acho que não presto para nada; (p <0,001); Eu gostaria de poder ter mais respeito comigo mesmo (p=0,016), e Eu, com certeza, me sinto inútil, às vezes (p=0,022). Associação negativa foi observada com: “No conjunto, eu estou satisfeito comigo” (p=0,022). Na análise ajustada, os adolescentes com dentes cariados apresentaram maior prevalência de respostas positivas para a questão Às vezes, eu acho que não presto para nada [RP= 1,23 (IC 95% 1,05; 1,44)] e maior prevalência de respostas negativas para a questão No conjunto, eu estou satisfeito comigo [RP= 1,12 (IC 95% 1,02; 1,24)]. Conclusão: Aspectos da autoestima foram, independente e significativamente, associados com a presença de dentes cariados.

Abstract Introduction Dental caries in adolescents remains an important public health problem, but its relationship with psychological factors are poorly studied. Objective To study the possible association between aspects of self-esteem and dental caries in adolescents. Material and method A cross-sectional study involving a sample of 409 adolescents from 13 Southern Brazilian municipalities was carried out. Dental caries status was assessed through the World Health Organization criteria. For questions related to self-esteem the Rosenberg Self-Esteem Scale was used. The outcomes were each question of the scale. The chi-square test was used to determine statistical significance of associations. To adjust for confounding variables, the Poisson loglinear with robust estimator was used. Result Positive associations were observed for the presence of decayed teeth and “At times, I think I am no good at all (p < 0.001), “I wish I could have more respect for myself (p= 0.016), I certainly feel useless at times (p= 0.022) and negative association with On the whole, I am satisfied with myself (p= 0.022). In the adjusted analysis, adolescents with decayed teeth had a higher prevalence of positive responses to At times, I think I am no good at all [(PR= 1.23 (CI 95% 1.05; 1.44)], and negative responses for On the whole, I am satisfied with myself [(PR= 1.12 (CI 95% 1.02; 1.24)]. Conclusion Aspects of self-esteem were significantly and independently associated with the presence of decayed teeth.

Impact of Dental Caries on Quality of Life of School Children

Objective: To estimate the impact of dental caries on the oral health-related quality of life of school children of public schools of Tubarão, Santa Catarina, Brazil. Material and Methods: A cross-sectional study on a sample of 42310-15 years old students was carried out. The prevalence of dental caries, dental trauma and malocclusion was observed by oral examination based on WHO criteria. The Oral Impact on Daily Performance indicator was used to collect data about the impact on quality of life related to children's oral health. The Chi-square test was used for bivariate analysis with significance levels set at p<0.05. Prevalence ratios (PR) and confidence intervals (95%) were estimated using log-linear Poisson regression with a robust estimator. Results: The prevalence of dental caries was 55.5%. The prevalence of impact on oral health related quality of life was 45.6%. OIDP dimensions significantly associated with dental caries were eating [PR = 1.45 (95%CI 1.06; 2.00)] (p = 0.021), sleeping [(PR = 2.29 (95%CI 1.15; 4.56)] (p = 0.018) and performing daily activities [PR = 2.57 (95%CI 1.06; 6.22)] (p = 0.036) after adjusting for gender, age and presence of dental trauma and malocclusion. Conclusion: Dental caries was found to be significantly associated with oral health-related quality of life of children in activities such as eating, sleeping, and performing daily activities.

O objetivo deste estudo foi propor um modelo para a avaliação da qualidade da atenção à saúde bucal da criança. O marco conceitual para a elaboração da matriz avaliativa foi composto por estudos de avaliação de serviços de atenção à saúde bucal no Brasil e em outros países, e levantamento e revisão das políticas públicas vigentes relacionadas à saúde da criança no Brasil. A qualidade da gestão municipal na atenção básica da saúde bucal infantil foi avaliada sob duas dimensões: Gestão e Provimento. Na primeira, foram dispostas duas subdimensões: articulação e recursos, e na segunda, mais duas subdimensões: promoção e prevenção, e diagnóstico e tratamento. A matriz de avaliação ficou composta por nove indicadores na dimensão de Gestão e nove na dimensão de Provimento. Os indicadores foram elaborados em oficinas com especialistas. O modelo tem condições de ser aplicado em municípios com diferentes portes populacionais, e permite identificar os pontos nos quais os gestores devem aperfeiçoar suas ações.

This article proposes a model for quality evaluation of oral health care in children. The conceptual framework for the evaluation matrix consisted of evaluation studies on oral health care services in Brazil and other countries and a survey and review of prevailing public policies for children's health in Brazil. Two dimensions, Management and Provision, were evaluated in the quality of municipal management of pediatric oral health care. Management included two component dimensions, articulation and resources, while Provision included two more, "promotion and prevention" and "diagnosis and treatment". The evaluation matrix consisted of nine indicators in the Management dimension and nine in the Provision dimension. The indicators were elaborated in workshops with specialists. The model proved appropriate for application in municipalities with different population sizes and allows identifying the areas where managers should improve their actions.

Introduction: Cancer of the lip, mouth and pharynx is a serious health problem. High incidence rates are found worldwide. In Brazil, the Southern and Southeastern regions have the highest incidences in the country. Objective: To describe 5 and 10-year survival rates in patients with cancer of the lip, mouth and pharynx at a referral center in Florianopolis, Santa Catarina, Brazil. Methods: Retrospective cohort study using data from patients diagnosed between January 1st and December 31st, 2001, with follow-up until December 31st, 2011. Descriptive analysis was performed and survival was estimated by Kaplan-Meier method. Cox semi-parametric model was used to estimate death risk. Results: Survival rates at 5 and 10 years were 33.3 and 26.9%, respectively. Advanced clinical stage in the diagnosis increased death risk by 2.88 and 2.51, respectively. Sex, ethnicity, level of education, previous diagnosis and treatment, as well as age, did not show significant association. Conclusion: Survival rate at 5 years was 33.3% and, at 10 years, was 26.9%. Advanced stage was an independent risk factor for death due to cancer of the lip, mouth and pharynx in both periods analyzed. .

Dental hot cold sensitivity and traumatic dental injuries

AIM: Although several studies have indicated negative impacts of traumatic dental injuries on children’s quality of life, virtually none of them have explored the possible association between them and the occurrence and dental hot cold sensitivity. The aim of this study was to study the possible association of hot cold dental sensitivity and history of traumatic dental injuries. MATERIAL AND METHODS: A cross sectional study involving a representative sample of 11 to 14 year old schoolchildren from 13 Brazilian municipalities was carried out. Data on traumatic dental injuries were collected through oral exanimations. Non clinical data were obtained through structured interviews on socio demographic profile and prevalence of dental hot cold sensitivity. Non conditional logistic regression analysis was performed for the presence of dental hot cold sensitivity controlled for gender, maternal schooling and history of dental caries. RESULTS: The prevalence of dental hot cold sensitivity was 30.3% and the prevalence of traumatic dental injuries was 16.6%. School children presenting traumatic dental injuries had 22% higher prevalence of dental hot cold sensitivity compared to those without it regardless other studied variables. CONCLUSIONS: A significant and independent association between dental hot cold sensitivity and history of traumatic dental injuries was observed.
