Relação entre a condição bucal de gestantes internadas e desfechos adversos na gestação / Relationship between the oral condition of hospitalized pregnant women and adverse pregnancy outcomes

Objetivo: avaliar se a condição bucal favoreceu a presença de desfechos adversos da gestação (DAG) em mulheres internadas e acompanhadas em um hospital escola. Métodos: um estudo de coorte retrospectiva com mulheres grávidas que foram internadas entre setembro de 2019 e início de março de 2020 e que continuaram o acompanhamento obstétrico. Resultados: Das 65 gestantes que seguiram acompanhamento, 27 (41,5%) dos bebês nasceram pré-termo e 20 (30,8%) com baixo peso, sendo que as duas condições estavam presentes em 15 crianças (23,1%), sendo significantemente relacionadas com a menor semana gestacional na internação. Ao relacionar diferentes fatores com o desfecho pré-termo, houve diferença significante em gestantes com a ocupação "do lar" e com o tempo de internação igual ou maior que 10 dias e com a presença de baixo peso ao nascer. Não foi observada relação dos dados avaliados da condição bucal das gestantes na internação com o parto pré-termo. Conclusões: Gestantes que necessitam de internação hospitalar durante a gravidez, independente da condição bucal, aumentam a possibilidade de apresentarem DAG, sendo fundamental a realização do correto acompanhamento pré-natal.(AU)

Objective: to assess whether the oral condition favored the presence of adverse effects during pregnancy in pregnant women hospitalized and followed up at a teaching hospital. Methods: a retrospective cohort study with mothers who were hospitalized during pregnancy between September 2019 and early March 2020 and who continued obstetric follow-up. Results: 83 pregnant women were interviewed and 65 were followed up Of the 65 pregnant women who followed up, 27 (41.5%) of the babies were born preterm and 20 (30.8%) with low birth weight, and both conditions were present in 15 children (23.1%), being significantly related to the shortest gestational week at admission. When relating different factors with the preterm outcome, there was a significant difference in pregnant women with the occupation "housewife" and with the length of hospital stay equal to or greater than 10 days and with the presence of low birth weight. There was no relationship between the evaluated data on the oral condition of pregnant women during hospitalization and preterm delivery. Conclusions: Pregnant women who require hospitalization during pregnancy, regardless of oral condition, increase the possibility of having negative pregnancy outcomes, and correct prenatal care is essential.

A internação da gestante pode afetar a condição bucal do filho no terceiro ano de vida? / Can a pregnant woman's hospitalization affect the child's oral condition in the third year of life?

Objetivo: Avaliar se a hospitalização na gestação pode influenciar na condição bucal do filho no terceiro ano de vida. Métodos: Estudo longitudinal com bebês de gestantes internadas e acompanhadas no setor da Obstetrícia de um Hospital Escola em Pelotas, RS, Brasil. Os dados referentes a hospitalização e ao parto foram coletados do prontuário hospitalar e no terceiro de vida do filho (a) de um questionário aplicado a mãe e do exame bucal da criança. Cada agravo bucal foi avaliado com critérios específicos, por uma examinadora calibrada e analisado no programa IBM SPSS Statistics com 5% de nível de significância. Resultados: Participaram 20 díades mãe-filho (a). Alterações da oclusão acometeram 95% das crianças, sendo a mordida aberta anterior (MAA) a principal. Ainda, 25% das crianças apresentaram opacidades demarcas e/ou hipoplasia do esmalte, sendo significativamente maior em filhos de mães mais jovens e 20% tinham cárie da primeira infância (CPI), estando relacionada à ausência de creme dental fluoretado e à qualidade da higiene bucal. Conclusão: O reflexo mais evidente da hospitalização na gestação na saúde bucal no terceiro ano de vida do filho (a) foi a oclusão alterada, especialmente a MAA.(AU)

Objective: To assess whether hospitalization during pregnancy can influence the child's oral condition in the third year of life. Methods: Longitudinal study with babies of pregnant women hospitalized and followed up in the Obstetrics sector of a Teaching Hospital in Pelotas, RS, Brazil. Data referring to hospitalization and childbirth were collected from the hospital records and in the child's third of life through a questionnaire applied to the mother and the child's oral examination. Each oral condition was evaluated with specific criteria, by a calibrated examiner and analyzed in the IBM SPSS Statistics program with a 5% minimum significance level. Results: 20 mother-child participated. Occlusion alterations affected 95% of the children, with anterior open bite (AOB) being the main. Still, 25% of the children had opacities and/or enamel hypoplasia, which was significantly higher in children of younger mothers, and 20% had early childhood caries, which is related to the absence of fluoride toothpaste and the quality of oral hygiene. Conclusion: The clearest reflection of hospitalization during pregnancy on oral health in the third year of the child's life was altered occlusion, especially the AOB.(AU)

Impact of dental caries severity and activity on oral health-related quality of life among children aged 8-11 years

Abstract Caries disease can lead to strong impact in terms of pain and suffering, to functional impairment, and to negative effects on quality of life. Studies have demonstrated that the impact on quality of life increases with dental caries severity, and few studies have assessed the relationship between caries activity and children's oral health-related quality of life (OHRQoL). This cross-sectional study aimed to assess the impact of dental caries severity and activity on the OHRQoL of schoolchildren. The study was conducted with a sample of children aged 8 to 11 years from Pelotas, southern Brazil. Children answered the Child Perceptions Questionnaire 8-10, and socioeconomic data were collected. Children's dental caries (Kappa value of 0.95), PUFA, traumatic dental injuries, and malocclusion were examined. The Mann-Whitney, Kruskal-Wallis, and Poisson regression tests were performed. A total of 119 children were included. Children with initial (mean ratio (MR) of 1.92; 95% confidence interval (95% CI) of 1.05-3.48), moderate (MR: 2.66; 95%CI: 1.44-4.90), and severe carious lesions (MR: 2.65; 95%CI: 1.46-4.79) had a greater impact on OHRQoL compared with those without carious lesions (p =0 .047). Children with active carious lesions exhibited a greater impact on OHRQoL (MR:1.53 and 95%CI: 1.11-2.11) when compared to those without active lesions (p = 0.019). The findings demonstrate an association between dental caries severity and activity and the OHRQoL of school-aged children.

Endodontic treatment during pregnancy: case series and literature review / Tratamento endodôntico na gestação: série de casos e revisão da literatura

ABSTRACT The aim of this paper is to provide a scientific basis for conducting safe root canal treatment in pregnant women, illustrating with case reports treated in the extension project Maternal-Child Dental Care at the Federal University of Pelotas. The scientific bases address the main doubts of professionals when performing prenatal dental care: use of radiographic examination, local anesthetics, prescription of medications, among other essential factors in the care of pregnant women. The assisted pregnant women sought care with dental pain. In two cases symptomatic irreversible pulpitis was diagnosed, while a third was experiencing acute apical periodontitis. Endodontic procedures were performed under controlled and standardized conditions. The root canals were prepared in a single session, using mechanical instrumentation with reciprocating kinematics (Wave One® Gold Primary - Dentsply Sirona), and the root canal length was determined by an electronic apex locator FinePex (Schuster). Root canal filling was performed by the single cone technique with Wave One® gutta-percha points. After endodontic treatment, coronal sealing was performed with composite resin A2 Z350 XT (3M ESPE). The care related to the gestational condition is highlighted, and the patients remain under monitoring. It is concluded that the use of apical locators and mechanical instrumentation, using reciprocating files associated with the single cone obturation technique with a standardized cone for each system, represents advances for the accomplishment of endodontic treatment in pregnant patients due to the shorter clinical time and greater comfort of the procedure.

RESUMO O objetivo deste trabalho é fornecer embasamento científico para condução do tratamento endodôntico em gestantes através de uma revisão de literatura e série de casos clínicos conduzidos em sessão única no projeto de extensão Atenção Odontológica Materno-infantil da Faculdade de Odontologia da Universidade Federal de Pelotas. As bases científicas abordam as principais dúvidas do profissional na condução do pré-natal odontológico: uso do exame radiográfico, anestésico local, prescrição de medicamentos, entre outros fatores essenciais no atendimento da gestante. As gestantes assistidas procuraram atendimento apresentando dor de origem dentária. Em dois casos foi diagnosticado pulpite irreversível sintomática, enquanto um terceiro se travava de periodontite apical aguda. Os procedimentos endodônticos foram realizados sob condições controladas e padronizadas, sob supervisão de um professor de Endodontia. O preparo dos canais radiculares foi realizado em sessão única, através de instrumentação mecanizada de cinemática reciprocante (Wave One® Gold Primary (Dentsply Sirona), sendo o comprimento dos canais determinado por meio de localizador foraminal FinePex (Schuster). A obturação dos canais foi realizada pela técnica do cone único com cones do sistema Wave One®. Após o tratamento endodôntico foi realizada blindagem coronária com resina composta cor A2 Z350 XT (3M ESPE). Os cuidados relacionados à condição gestacional estão destacados, sendo que as pacientes permanecem em acompanhamento no projeto. Conclui-se que o uso de localizadores foraminais e da instrumentação mecanizada, utilizando limas reciprocantes associadas à técnica de obturação com cone único padronizado para cada sistema representam avanços para a realização do tratamento endodôntico em pacientes gestantes devido ao menor tempo clínico e maior conforto do procedimento.

Tabus e mitos da atenção odontológica na gestação: um estudo observacional de base hospitalar / Taboos and myths for the dental care during pregnancy: an observational study with a hospital basis

Objetivo: avaliar gestantes internadas no setor de obstetrícia do Hospital Escola da UFPel quanto à necessidade de receber atendimento odontológico de urgência, ao conhecimento a respeito do atendimento durante a gravidez e de como prevenir a doença cárie dentária em seus filhos. Método: este estudo observacional, de base hospitalar e transversal, foi conduzido a partir de instrumento contendo uma entrevista e uma avaliação bucal de 83 gestantes. Os dados foram coletados junto ao leito por dois residentes treinados e avaliados pelo Teste Exato de Fisher e por análise multivariada, com Regressão de Poisson e variância robusta. Resultados: a média de idade das gestantes foi de 28,7 anos, sendo que 31,3% relataram dor dentária, estando relacionada à atividade de cárie e à busca de atendimento odontológico nos últimos 6 meses. Das gestantes avaliadas, 66,2% apresentaram, pelo menos, um tabu ou mito, sendo que realizar tratamento endodôntico foi o mais prevalente. Realizar pré-natal reduziu a presença de tabus ou mitos. Apenas 7,2% das mulheres demonstraram ter conhecimento de como prevenir a doença cárie dentária no filho, sendo significativamente maior nas donas de casa e nas que receberam orientação prévia. Conclusão: o pré-natal favoreceu a redução da presença de tabus e mitos da odontologia na gestação. O cirurgião-dentista tem um papel importante na condução do pré-natal odontológico, para evitar e tratar as odontalgias na gestação e orientar sobre a saúde bucal dos filhos, efetivando a atenção odontológica nos mil dias da criança.(AU)

Evaluate pregnant women admitted to the Obstetrics department at UFPel School Hospital regarding the need to receive urgent dental care, knowledge about this care during pregnancy and how to prevent dental caries in Their child. Method: This observational, hospital-based and cross-sectional study was conducted using an instrument containing an interview and an assessment of the oral cavity of 83 pregnant women. The data were collected at the bedside by trained residents and evaluated by Fisher's exact test and multivariate analysis, using Poisson Regression with robust variance. Results: The average age of the pregnant women was 28.7 years, with 31.3% reporting dental pain, being related to dental caries and dental care-seeking in the last 6 months. Of the pregnant women evaluated, 66.2% had at least one taboo or myth, and endodontic treatment was more prevalent. Prenatal care reduced the presence of taboos or myths. Only 7.2% of women demonstrated knowledge of how to prevent dental caries disease in their child, being significantly higher in housewives and those who received prior guidance. Conclusion: Prenatal care favored the reduction of the presence of taboos and myths about dentistry during pregnancy. The dentist has an important role in the conduction of dental prenatal care, to prevent and treat toothache during pregnancy and to advise on the oral health of their child, providing dental care in the child's first thousand days.(AU)

Condição bucal de mulheres com diabetes mellitus gestacional internadas em um hospital escola no sul do Brasil / Oral condition of women with gestational diabetes mellitus admitted in a school hospital in southern Brazil

Objetivo: avaliar a condição bucal de mulheres com diabetes mellitus gestacional (DMG) internadas no Hospital Escola (HE) da Universidade Federal de Pelotas (UFPel). Métodos: trata-se de um estudo transversal retrospectivo de base hospitalar, em que dois residentes treinados realizaram a coleta dos dados por meio da avaliação dos prontuários médicos e odontológicos, no período de setembro de 2019 a março de 2020. Os dados socioeconômicos e demográficos e o diagnóstico de DMG foram coletados dos prontuários médicos, enquanto hábitos e condição bucal, dos prontuários odontológicos. A análise dos dados foi realizada no programa Stata 11.0, usando os testes Exato de Fisher e Regressão de Poisson. Resultados: foram avaliados os prontuários de 83 gestantes, destas, 37 (44,6%) apresentavam DMG. A presença de DMG esteve asso-ciada com as gestantes de maior faixa etária (62,2%) e no terceiro trimestre de gestação. Em sua maioria, tinham renda de até dois salários mínimos, eram solteiras, tinham filhos e realizaram pré-natal. Em relação à avaliação bucal, apenas a presença de cálculo dental e inflamação gengival foi estatisticamente associada à presença de DMG (p= 0,030 e 0,014 respectivamente). A autopercepção do sorriso foi considerada ruim por 40,5%, e a maioria teve dentes perdidos por cárie (64,9%). Conclusões: a prevalência de DMG foi alta entre as gestantes internadas, sendo maior em mulheres de mais idade. Presença de cálculo dental e inflamação gengival foram fortemente associadas à presença de DMG, enquanto hábitos bucais e presença de cárie não apresentaram associação. Novas pesquisas, com exames periodontais completos, são necessárias para verifi-car as condições periodontais dessas mulheres.(AU)

Aim: to assess the oral condition of women with Gestacional Diabetes Mellitus (GDM) admitted in a School Hospital (HE)/UFPel. Methods: medical and dental records, from September 2019 to March 2020, were evaluated in this hospital-based retrospective cross-sectional study. Socioeconomic and demographic data were collected from medical records, while oral condition and habits were obtained from the dental records. Statistical analysis was performed with Stata 11.0 software using Fisher's exact test and Poisson regression. Results: the medical records of 83 pregnant women were evaluated, of which 37 (44.6%) had GDM. The presence of GDM was associated with pregnant women of older age (62.2%) and most in the third trimester of pregnancy. Most of them had an income of up to two minimum wages, were single, had children and underwent prenatal care. Regarding the oral evaluation, only the presence of dental calculus and gingival inflammation was statistically associated with the presence of GDM (p = 0.030 and 0.014 respectively). The self-perception of the smile was considered bad to 40.5% and many of them had lost teeth due to caries (64.9%). Conclusions: the prevalence of GDM was high in hospitalized pregnant women, being higher in older women. Presence of dental calculus and gingival inflammation were strongly associated with the presence of GDM, while oral habits and the presence of caries were not associated. Further research, with complete periodontal examinations is necessary to verify the periodontal conditions of these women.(AU)

Influence of pregnancy on the inflammatory process following direct pulp capping: a preliminary study in rats

Abstract The purpose of this study was to evaluate the inflammatory process following direct pulp capping during pregnancy. This experimental study involved 48 maxillary first molars of female Wistar rats. The procedures were performed in pregnant and non-pregnant animals (n =20 each). Direct pulp capping with mineral trioxide aggregate (MTA) and restoration with a light-cured resin composite was performed in half of exposed pulp specimens. In the other half of specimens, light-cured composite was placed directly on the exposed pulp. In the control groups (n=4 each), no intervention was performed. Animals were euthanized at 3 and 7 days. All sections (three per slide) were viewed under an optical microscope. One previously calibrated pathologist performed descriptive analysis and assigned scores for inflammatory response and tissue organization adjacent to the pulp exposure. The Kappa value for intra-examiner variability was 0.91. At 3 days, in animals treated with MTA, inflammatory infiltrate was absent in non-pregnant animals while mild inflammatory infiltrate was observed in some pregnant animals. The inflammatory response ranged from mild to severe in both groups treated with composite alone. At 7 days, the inflammatory response was more intense in pregnant than in non-pregnant animals treated with MTA; while this difference were not evident in animals treated with composite alone. In conclusion, pregnancy may not influence the inflammatory process following direct pulp capping with light-cured resin composite, which was always harmful to the pulp; while the tissue response after the direct pulp with MTA were more favorable in non-pregnant animals.

Resumo O objetivo deste estudo foi avaliar o processo inflamatório do tecido pulpar após o capeamento pulpar direto, realizado durante a gestação. Este estudo experimental envolveu 48 primeiros molares superiores de ratos Wistar fêmeas. Os procedimentos foram realizados em animais prenhes e não prenhes (n=20). Após as exposições pulpares, o capeamento pulpar direto foi efetuado com agregado trióxido mineral (MTA) ou restauração direta com resina composta. Nos grupos controle (n=4), nenhuma intervenção foi realizada. Os animais foram submetidos à eutanásia após 3 e 7 dias. Todos os cortes foram avaliados através de um microscópio ótico. Um patologista previamente calibrado realizou analise histológica descritiva e estabeleceu escores para intensidade da resposta inflamatória e para o grau de organização tecidual na região adjacente à exposição pulpar. O valor de Kappa intra-examinador foi 0,91. No período experimental de 3 dias, nos animais tratados com MTA, o infiltrado inflamatório estava ausente nos não prenhes, enquanto infiltrado inflamatório moderado estava presente nos animais prenhes. A resposta inflamatória variou de moderada a severa em ambos os grupos tratados apenas com resina composta. Após o periodo experimental de 7 dias, a resposta inflamatória foi mais intensa nos animais prenhes que nos não prenhes do grupo do MTA, enquanto esta diferença não foi tão evidente nos animais que receberam capeamento pulpar direto com resina composta. Pode-se concluir, que a gestação pode não exercer influência no processo inflamatório do tecido pulpar após proteção pulpar direta com resina composta; a qual foi sempre danosa aos tecidos pulpares. No entanto, a resposta tecidual ao capeamento pulpar com MTA foi mais favorável nos animais não prenhes.

Fatores maternos relacionados à alta frequência de consumo de sacarose por crianças acompanhadas por um programa de atenção odontológica materno-infantil nos dois primeiros anos de vida / Maternal factors related to the high frequency of sucrose intake by children followed-up by a maternal and child dental care program in the first two years of life

Objetivo: avaliar se os hábitos alimentares maternos relatados durante a gestação influenciam a ingestão de sacarose das crianças nos primeiros dois anos de vida. Sujeitos e método: participaram da pesquisa 204 díades mãe-filho acompanhadas por um programa de atenção odontológica materno-infantil em uma cidade no sul do Brasil. As variáveis independentes foram obtidas por meio dos prontuários odontológicos disponibilizados pelo programa. Os hábitos alimentares maternos foram coletados durante a gestação e a ingestão diária de sacarose pelas crianças foi baseada em um questionário alimentar de frequência, dicotomizado em < 4 vezes/ dia e ≥ 4 vezes/dia. A análise multivariada foi realizada com modelos de regressão de Poisson, com variância robusta para estimar a razão de prevalência e os intervalos de confiança de 95%. Resultados: a prevalência do consumo de sacarose nos primeiros dois anos de vida, com uma elevada ingestão de sacarose (≥ 4 vezes/dia), foi detectada em 90,69% das crianças. Após o ajuste, o desfecho (alta ingestão de sacarose) foi 10% maior para as crianças cujas mães relataram beber bebida açucarada para satisfazer sua sede durante a gestação [RP = 1,10 (IC95%: 1,02-1,18)]. Conclusões: a maioria das crianças apresentou alta ingestão de sacarose em idade precoce. A triagem de mulheres grávidas para consumo de bebidas açucaradas pode ser uma maneira possível de reconhecer crianças em risco futuro de alta ingestão de sacarose na primeira infância. (AU)

Objective: to assess whether maternal eating habits reported during pregnancy influence their children's sucrose intake in the first two years of life. Subjects and method: a total of 204 mother-child dyads followed-up by a maternal and child oral care program in southern Brazil participated in the study. The independent variables were obtained from dental records provided by the program. The maternal eating habits were collected during pregnancy and the daily sucrose intake of the children was based on a frequency food questionnaire dichotomized in <4 times/day and ≥4 times/day. The multivariate analysis was performed using Poisson regression models with robust variance to estimate the prevalence ratio and the 95% confidence intervals. Results: the prevalence of sucrose intake in the first two years of life was high. A high sucrose intake (≥4 times/ day) was detected in 90.69% of the children. After adjustment, the outcome (high sucrose intake) was 10% higher for children whose mothers reported drinking sugar-sweetened beverages to satisfy their thirst during pregnancy [PR = 1.10 (95%CI: 1.02-1.18)]. Conclusion: most of the children presented a high sucrose intake at an early age. Screening pregnant women for sugar- -sweetened beverage intake may be a potential way to recognize the children at risk for future high sucrose intake in early childhood. (AU)

Objective: this study aimed to assess the use of dentalservices in a southern Brazilian city by children aged12-18 months and to verify the relationship betweensocioeconomic and demographic variables, as well asmaternal use of dental services, and presence of dentalcaries in the children. It also aimed to describe theprevalence of use of dental services by variables of disparity.Subjects and method: this cross-sectional studywas performed on the National Children's VaccinationDay in 12 public health care centers in Pelotas, RS, Brazil.The data on demographic and socioeconomic status(children's sex, number of children, family income, andmaternal education), pattern of maternal use of dentalservices, and children's first dental visit were collectedusing a semi-structured interview answered by themothers. Clinical examination was performed to assessdental caries in the children. Chi-square and Fisher'sexact tests were performed to analyze the associationsand an equiplot graph investigated disparities in the prevalenceof the first dental visit of preschoolers. Results:most children had never been to the dentist (93.4%).The bivariate analysis showed that children who hadnever been to the dentist belonged to families with lowerincome, and their mothers presented low level ofeducation and did not use dental services. Conclusion:most children aged 12-18 months had never been to thedentist and there is a socioeconomic disparity in the useof dental services by preschool children. (AU)

Objetivos: avaliar o uso do serviço odontológico em uma cidade do sul do Brasil por crianças de 12 a 18 meses de idade; verificar a relação entre variáveis socioeconômicas, demográficas, uso de serviço odontológico materno e presença de cárie dentária nas crianças; e descrever a cobertura do uso do serviço odontológico por variáveis de disparidade. Sujeitos e método: este estudo transversal foi realizado no Dia Nacional de Vacinação Infantil em doze centros de saúde pública em Pelotas, Rio Grande do Sul, Brasil. Os dados sobre status demográfico e socioeconômico (sexo da criança, número de filhos, renda familiar e educação materna), padrão de uso de serviço odontológico materno e primeira consulta odontológica infantil foram coletados por meio de uma entrevista semiestruturada com as mães. Foi realizado exame clínico para avaliação de cárie dentária nas crianças. O teste Qui-Quadrado e o teste exato de Fisher foram realizados para analisar as associações, e um gráfico equiplot investigou disparidades na cobertura da primeira visita odontológica de pré- -escolares. Resultados: a maioria das crianças nunca foi ao dentista (93,4%). A análise bivariada mostrou que as crianças que nunca foram ao dentista eram de famílias com menor renda, cujas mães tinham níveis baixos de escolaridade e não usavam o serviço de atendimento odontológico. Conclusão: a maioria das crianças de 12 a 18 meses nunca foi ao dentista. Há uma disparidade socioeconômica no uso de serviços odontológicos por crianças pré-escolares. (AU)

Pacifier use modifies the association between breastfeeding and malocclusion: a cross-sectional study

Abstract This study aimed to evaluate the influence of breastfeeding and pacifier use on the occlusal status of preschool children. A cross-sectional study was conducted with children (n = 489) aged 2-5 years in private and public schools in Pelotas, South Brazil. Mothers answered a questionnaire on demographic, socioeconomic and behavioral variables, including breastfeeding and non-nutritive sucking habits. Malocclusion was classified as normal/mild and moderate/severe, according to WHO criteria. The association between breastfeeding and pacifier use with malocclusion was tested using multivariate logistic regression. The prevalence of malocclusion was 37.83% (95%CI 33.52-42.14), and 57.87% of the children used a pacifier. A total of 46.01% of the sample was exclusively breastfed for 6 months, and 24.74% were never breastfed. Malocclusion was associated with pacifier use, and with both non-exclusively breastfed and never breastfed. After adjustments for demographic and socioeconomic variables, the children who used a pacifier and were never breastfed (OR = 19.08; 95%CI 8.54-42.63), or who used a pacifier and were not exclusively breastfed (OR = 13.74; 95%CI 6.11-30.92), showed worse occlusal conditions, compared with the children who were exclusively breastfed and never used a pacifier. Pacifier use modifies the relationship between breastfeeding and occlusal status.

Physicochemical and Biological Evaluation of Endodontic Filling Materials for Primary Teeth

Abstract This study assessed the pH, radiopacity, antimicrobial effect, cytotoxicity and biocompatibility of endodontic filling materials for primary teeth. Zinc oxide eugenol (ZOE), Vitapex and Calen paste thickened with zinc oxide (ZO) were evaluated in comparison to an experimental MTA-based material. Radiopacity was tested using a graduated aluminum stepwedge with a digital sensor (n=5). The materials pH was recorded at 1, 4, 12 h; 1, 3, 7, 15 and 30 days (n=5). Direct contact test was used to assess the antimicrobial efficacy against Enterococcus faecalis after 1, 4, 12, 24 h (n=5). Cytotoxicity assay used MTT test for cell viability after incubation for 1, 3 and 7 days (n=5). For biocompatibility test, Wistar rats had received implants containing each material (n=5). The biopsied tissues were histologically analyzed after 15, 30 and 60 days. The results of radiopacity, pH, antimicrobial capacity and cytotoxicity were analyzed using ANOVA and Tukey tests. The histological data were submitted to Kruskal-Wallis test. The experimental material presented the lowest radiopacity (3.28 mm Al) and had a pH>12.0 throughout the test period. The experimental material showed the highest antibacterial effect, killing over 99.97% bacteria in 4 h. Vitapex presented the highest cell viability. Initially, biocompatibility test showed moderate to severe inflammation in all groups. After 60 days, Calen+ZO group showed moderate inflammation, while the others showed predominantly mild inflammatory reaction. The present results demonstrated that the experimental MTA-based material exhibited satisfactory behavior regarding the studied properties. Additional in vivo studies are necessary for a better evaluation of the material.

Resumo Este estudo avaliou o pH, radiopacidade, efeito antimicrobiano, citotoxicidade e biocompatibilidae de materiais obturadores de dentes decíduos. Foram avaliados o cimento de óxido de zinco e eugenol (OZE), Vitapex e pasta Calen espessada com óxido de zinco (OZ), comparativamente a um material experimental à base de MTA. A radiopacidade foi testada usando uma escala milimetrada de alumínio, com um sensor digital. O pH dos materiais também foi avaliado nos períodos de 1, 4, 12 h; 1, 3, 7, 15, e 30 dias (n=5). O teste de contato direto foi utilizado para avaliação da atividade antimicrobiana dos materiais conta uma cepa de Enterococcus faecalis após incubação por 1, 4, 12, e 24 h (n=5). Para avaliação da citotoxicidade foi utilizado o teste de MTT para avaliação da viabilidade celular. No teste de biocompatibilidade, ratos Wistar receberam implantes subcutâneos contendo cada material obturador (n=5). Após biópsia, os tecidos foram submetidos à avaliação histológica em períodos de 15, 30 e 60 dias. Os resultados de radiopacidade, pH, ação antimicrobiana e citotoxicidade foram analisados usando os testes ANOVA e Tukey. Os dados histológicos foram submetidos ao teste de Kruskal-Wallis. O material experimental apresentou a menor radiopacidade (3.28 mm Al) e apresentou um pH superior a 12,0 durante todo o período experimental. O material experimental apresentou o maior efeito antimicrobiano, eliminando mais de 99,97% das bactérias em um período de 4 h. O Vitapex permitiu uma maior viabilidade celular em comparação aos demais materiais avaliados. Inicialmente, os testes de biocompatibilidade demonstraram inflamação de moderada a severa em todos os grupos. Após 60 dias, apenas o grupo Calen+ OZ apresentou inflamação moderada, enquanto os outros materiais demonstraram predominantemente a indução de inflamação leve. Os resultados demonstraram que o material experimental à base de MTA exibiu comportamento satisfatório com relação às propriedades avaliadas. Estudos adicionais, in vivo, são necessários para uma melhor avaliação do material.

Epidemiology of malocclusions in primary dentition and associated factors

This study aimed to evaluate malocclusion occurrence in children with complete primary dentition, describing the most frequent one and verifying potential associations with demographic, socioeconomic, and behavioral variables. Subjects and method: 502 children with complete primary dentition from primary schools in the city of Pelotas, RS, Brazil, were examined. Data was collected based on questionnaires distributed to the mothers, as well as on physical examinations of the oral cavity. The children with malocclusion presented at least one of the following changes: anterior open bite, deep overbite, posterior crossbite, and overjet. Chi-square tests for heterogeneity and linear trend were used to verify associations with demographic, socioeconomic, and behavioral variables. Results: the occurrence of malocclusions in the population studied was 67.5%. From them, 33.6% presented anterior open bite, 22.3% presented deep overbite, 9.8% presented posterior crossbite, and overjet was present in 1.8%. The most frequent malocclusion was anterior open bite, which was directly associated with the use of pacifier (p<0.001), duration of use (p<0.001), and frequency use (p<0.001). There was also an inverse association with children's age (p=0.007) and maternal level of education (p=0.016). An association was found between the number of children and anterior open bite (p=0.039). Conclusion: the population studied presented high prevalence of malocclusions, and anterior open bite was the most frequent one, which was associated with the use of pacifier, as well as the duration and frequency of use.

Black stains and dental caries in Brazilian schoolchildren: a cross-sectional study

Abstract The aim of this study was to assess the prevalence of black stains (BS) and factors associated with their occurrence and to investigate the association of BS with caries experience after adjusting for other risk indicators. A school-based, cross-sectional study using multistage sampling of children aged 10-12 years from 20 private and public schools in Pelotas/Southern Brazil was conducted (n = 706). Children were evaluated for BS and dental caries (DMFT/dmft index) and socioeconomic information was collected by questionnaire. Univariate and multivariate Poisson regressions were used to assess variables associated with the prevalence of BS and with caries experience. The prevalence of BS was 5.81%. The mean DMFT/dmft was 1.54 (±1.91), with a maximum value of 10. Among the children with BS, mean dmft/DMFT was 1.22 (SD 1.68), with a maximum value of 6. After adjustments for demographics and socioeconomic variables, dental plaque and tooth brushing habits, prevalence of BS was associated with lower caries experience (RR 0.67; 95%CI 0.49-0.92). In conclusion, the presence of BS showed an association with lower dental caries experience in the evaluated population. Future studies should investigate the mechanisms behind this association.

Hematomas de erupção: relato de três casos clínicos em bebês / Eruption hematomas: report of 3 clinical cases in infants

Introdução: Os cistos de erupção são considerados um tipo de cisto dentígero e podem ocorrer na dentição decídua. Essa patologia ocorre quando o dente apresenta dificuldade para vencer resistências e irromperna arcada dentária, permanecendo a face oclusal ou incisal de sua coroa recoberta por um capuz de mucosa gengival, favorecendo um processo inflamatório de natureza traumática. Objetivo: o objetivo deste artigo éapresentar três casos clínicos de hematomas de erupção associados aos dentes decíduos em bebês atendidos no projeto Atenção Odontológica Materno-Infantil da Faculdade de Odontologia da Universidade Federal dePelotas, Rio Grande do Sul, Brasil, e a conduta adotada. Relato de casos: os casos apresentados são de uma menina de dez meses e de dois meninos, um com treze e outro de dezoito meses de idade, cujas mães relataram a presença de uma alteração de coloração azulada. Nos três casos foi realizada a drenagem do cisto devido ao relato de choro da criança desde o aprecimento do cisto, de alteração na cronologia de erupção e de dificuldade de alimentação da criança, respectivamente.Considerações finais: dessa forma, em caso de hematoma de erupção em bebês, cabe ao profissional orientar a família e, quando necessário, intervir, pois é um procedimento simples e resolutivo.

Natal and neonatal teeth: A report of three cases

The occurrence of natal and neonatal teeth is relativity rare. General dental practitioners should be aware of these conditions and be prepared to provide appropriate care for patients. The aim of this study is to describe two cases of neonatal teeth and one case of natal teeth, highlighting the importance of the treatment decision. In all of these cases the teeth were part of the normal series of primary dentition. In case 1 the tooth was extracted because of a possibility of aspiration. In cases 2 and 3 the teeth were monitored and parents were instructed about the necessary care, especially the need for good oral hygiene. In conclusion, each patient must be evaluated individually with radiographic and clinical examinations and the best treatment option should always be chosen taking into account parents' views. Keywords: Natal teeth; Infant, Newborn; Tooth, Deciduous.

A ocorrência de dentes natais e neonatais é relativamente rara. Os cirurgiões-dentistas devem estar preparados para fornecer o cuidado adequado aos pacientes com essa condição. O objetivo deste estudo foi apresentar dois casos de dentes neonatais e um de dentes natais e destacar a importância da decisão do tratamento. Em todos os casos apresentados, os dentes faziam parte da série normal da dentição decídua. No caso 1 o dente foi extraído devido à possibilidade de aspiração. Nos casos 2 e 3, os dentes foram monitorados e os pais foram informados da necessidade de higiene bucal adequada. Concluindo, cada paciente deve ser avaliado individualmente através de exames clínicos e radiográfi cos.

Evaluation of a feasible educational intervention in preventing early childhood caries

Early childhood caries (ECC) in the primary dentition of preschoolers remains high. Young children have limited access to oral healthcare, and oral health education (OHE) measures can be a valuable tool to prevent caries in this population. The aim of this study was to evaluate the impact of an early educational intervention on ECC prevention. The study group (SG) comprised 271 children aged 0-12 months and their mothers, who attended 12 selected public health centers (PHC). The SG received oral health instructions from a pamphlet and by verbal explanation of some topics. One year later, a similar sample of children from another 12 PHCs were selected to serve as the control (CG; n = 251). The children were examined to determine their caries status: decayed = cavitated and/or white spot lesion (maxillary anterior surface); missing; and filled surface index > 0. There was a one-year follow-up. Socioeconomic and demographic information was collected. Logistic regression was used to estimate the effects of the educational intervention on the ECC odds. A sample of 445 (SG = 194 and CG = 251) children remained to the end of the study and were examined. The prevalence of caries was 12.9% in the SG and 17.9% in the CG. The odds of caries were 80% higher in the CG than in the SG (p = 0.037). The strategy of providing OHE from a pamphlet and with a brief verbal instruction to mothers during their child’s first year of life can constitute a valuable tool for ECC prevention.

Prevalence of Teething Symptoms in Primary Teeth and Associated Factors: Cross-Sectional Study in Children aged 12-23 months in Pelotas, Brazil

To identify the main teething symptoms reported by mothers and associated factors. Material and Methods:Cross-sectional study conducted with mothers of children aged 12-23 months visiting 12 public health care centers during National Children Vaccination day in Pelotas, Rio Grande do Sul, Brazil, in 2011. Mothers were interviewed and information on teething symptoms and socioeconomic (family structure, income, maternal schooling and child skin color) and demographic variables (maternal age and child sex) was collected. Chi-square, Fisher exact test and Poisson regression analyses were performed (P<0.05). Results:A total of 188 mother-child pairs were interviewed. Teething symptoms were reported by 91.93% mothers. Symptoms most frequently reported were excessive salivation (67.7%), irritability (65.2%), fever (44.1%), feeding difficulty (34.2%) and sleep disturbance (31.7%). Teething symptoms were not associated with socioeconomic and demographic variables investigated (p>0.05). Conclusion:Most mothers linked children symptoms with primary teeth eruption. Excessive salivation and irritability were the symptoms most reported by mothers. Socioeconomic and demographic variables were not statistically associated with maternal report of teething symptoms in their children. Dentists should provide adequate orientation to mothers and follow up their children. Dentists should refer to medical care services if symptoms persist, once these symptoms can be attributed to other causes...

Amelogênese imperfeita: aspectos clínicos e tratamento / Amelogenesis imperfecta: clinical aspects and treatment

O objetivo deste trabalho foi apresentar uma revisão de literatura, avaliando aspectos clínicos e opções de tratamento da amelogênese imperfeita, com a intenção de fornecer ao cirurgião-dentista subsídios para o diagnóstico e escolha de tratamento mais apropriado, levando em consideração a individualidade de cada caso. Apesar de a amelogênese imperfeita ser uma doença rara, em que a formação do esmalte é afetada, o profissional deve estar preparado para lidar com a situação e fornecer o suporte, tanto clínico quanto emocional, necessário para esses pacientes. Historicamente, pacientes com essa condição eram tratados com extrações e a confecção de próteses totais. Entretanto, atualmente é possível restaurar estética e função a níveis aceitáveis e como consequência interferir positivamente no comportamento e autoestima do paciente. Estudos com maior tempo de acompanhamento ainda são necessários, com o intuito de verificar a durabilidade dos diferentes materiais e técnicas restauradoras em casos de amelogênese imperfeita.

The purpose of this article is to present a review regarding clinical aspects and treatment alternatives for AmelogenesisImperfecta with the intention of facilitating dentists? diagnosis and most appropriate treatment choices, taking into account the peculiarities of each case. Although AmelogenesisImperfecta is a rare disease that affects enamel formation, professionals must be prepared to deal with this condition to give the clinical and emotional support needed by patients. Historically, patients with AmelogenesisImperfecta were treated by means of extractions and by the use of fully removable dentures. However, it is possible to restore esthetics and function to an acceptable level that can positively affect the patient?s self-confidence and behavior nowadays. Patient long-term follow up studies are still needed in order to verify the durability of the different materials and restorative techniques in AmelogenesisImperfecta cases.

Granuloma gravídico - relato de caso / Granuloma gravidarum - case report

O granuloma piogênico é uma das entidades mais frequentemente associadas à expansão dos tecidos moles. Em gestantes, é comumente denominado granuloma gravídico ou tumor gravídico. Acreditase que essa lesão, de natureza não neoplásica, represente uma resposta tecidual exuberante a uma irritação local ou trauma. Hormônios sexuais femininos estão relacionados com a patogênese dessa lesão. Esse relato apresenta o caso de uma paciente de 27 anos, no oitavo mês gestacional, com granuloma gravídico na região de mucosa vestibular do dente 42 que estava interferindo na qualidade de vida da paciente. Foi realizada a biópsia excisional da lesão. Dependendo do volume, o granuloma piogênico tende a regredir por completo, após o término da gestação, no entanto, em alguns casos, deve-se considerar a remoção cirúrgica da lesão, uma vez que ela pode interferir na alimentação, no convívio social e matrimonial, fatores importantes para que a gestação evolua adequadamente. Embora a paciente não tenha retornado para avaliação do pós-operatório imediato e mediato, foi relatado, por contato telefônico, que não houve recidiva da lesão, decorridos 18 meses do procedimento cirúrgico.

Pyogenic granuloma is an entity often associated with expansion of soft tissues. In pregnant women is commonly called granuloma gravidarum or pregnancy tumor. This lesion, non-neoplastic nature, is considered a represent of an exuberant tissue response to local irritation or trauma. Female sex hormones are related to the pathogenesis of this lesion. This report presents the case of a 27-year-old patient in the eighth month of pregnancy, with granuloma gravidarumon the buccal mucosa, region of tooth 42, that was interfering with quality of life of the patient. Lesion excisional biopsy was performed.Depending on the volume, the pyogenic granuloma tends to regress completely after pregnancy, but in some cases it is necessary to consider the surgical removal of the lesion, because the granuloma could modify the diet, social life and marriage, important factors to adequate pregnancy development. Although the patient has not returned for immediate and mediate postoperative evaluation, it was reported, by telephone, no lesion recurrence after 18 months of the surgery.

Dental emergencies in a university pediatric dentistry clinic: a retrospective study

A significant number of children visit a dentist for the first time due to emergency situations. However, little is known regarding the prevalence, etiology, and treatment provided for children at emergency dental visits. This study aimed to evaluate the profile of children attending a dental school emergency clinic, the reasons for seeking dental care, and the treatment provided. Records of 270 patients who attended an emergency clinic during 2010 were analyzed, and 253 were selected. Demographic, diagnostic, and procedural information was collected. The mean child age was 7.8 years. For 208 children (82%), pain was the main reason for the emergency visit. Nearly 79% of the visits were due to caries, and the most frequently required treatment was endodontic intervention (31.22%). Of the decayed teeth, 61.70% were primary posterior teeth and 31.9% permanent posterior teeth. Pain caused by dental decay was the most frequent chief complaint. A large number of children were brought to the dentist with complaints that had started long before, for which over-the-counter medications had been used.
