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)

Translation and cultural adaptation of the Illness Perception Questionnaire-Revised for Dental to Brazil.

This study aimed to translate and to perform the cultural adaptation of the instrument Illness Perception Questionnaire-Revised for Dental (IPQ-RD) into Brazilian Portuguese. The IPQ-RD consists of 34 items that assess the cognitive and emotional representation/perception of parents/caregivers of children with dental caries, with response options on a 5-point Likert scale, ranging from "Strongly agree" (score 1) to "Strongly disagree" (score 5). The higher the score, the lower the perception of the disease. The protocol consists of translation into Brazilian Portuguese, back-translation into English, revision by an Expert Review Committee, and pre-test (application in parents/caregivers of children in dental care). For some questions, the translated versions were identical (T1 = T2); for others, one version was preferred (T1 or T2); for still others, it was decided to modify terms to obtain greater clarity on the item (T3). In the first pre-test, three questions were misunderstood by more than 15% of the sample, after which the items were reviewed by the Expert Review Committee. In the second pre-test, the adapted version was applied to a new sample of parents/caregivers (n = 15) and the questions were understood by more than 85% of the participants. The Brazilian Portuguese version of the IPQ-RD was well understood by the evaluated population.

Translation and Cultural Adaptation of the Modified Child Dental Anxiety Scale - Faces (MCDASf) into Brazilian Portuguese

Abstract Objective: To translate and culturally adapt the Modified Child Dental Anxiety Scale - Faces (MCDASf) into Brazilian Portuguese. Material and Methods: The MCDASf consists of eight questions about anxiety toward dental procedures that are answered on a five-point Likert scale ranging from "not worried" (1 point) to "very worried" (5 points). The answers correspond to a scale of face drawings ranging from extremely negative to extremely positive. The process consisted of initial translation, back-translation, expert committee review, and pretesting. Results: The first revised version was applied to 32 children aged 5 to 12 years, 16 from the city of Governador Valadares, Brazil (southeastern region) and 16 from the city of Pelotas, Brazil (southern region). In the first pretest, Item 5 was misunderstood by 6.25% of children in the southern region; Item 6 by 6.25% in both regions; Items 7 and 8 by 87.5% and 100% of those from the southeastern region, respectively, and by 12.5% and 25% of those from the southern region, respectively. Items 7 and 8 were modified by the expert committee, and the second revised version was applied to 32 children, 16 from each region. The only misunderstood items were 4 and 5, both by a 7-year-old boy in Governador Valadares. Conclusion: The Brazilian Portuguese version of the MCDASf was well understood by the sample of children (AU).

Medo odontológico e saúde bucal: avaliação transversal do ciclo do medo entre universitários brasileiros / Dental fear and oral health: cross-sectional evaluation of the cycle of dental fear theory among Brazilian undergraduate students

Objetivo: Avaliar a presença do medo odontológico em universitários brasileiros e observar se a teoria do ciclo vicioso do medo é identificada nesta população. Materiais e métodos: Foi realizado um estudo transversal com universitários ingressantes na Universidade Federal de Pelotas em 2016. Os dados sociodemográficos, medo odontológico, o uso de serviços odontológicos, a percepção de cárie e dor dentária foram coletados através de um questionário auto--administrado. A exposição do estudo foi medo odontológico, e os desfechos incluíram padrão de consulta odontológica, experiência de cárie e dor dentária e autopercepção de saúde bucal. Características sociodemográficas foram incluídas como fatores de confusão. Para testar a associação do medo odontológico com os desfechos, foram utilizados modelos de regressão de Poisson com variância robusta, a fim de estimar as Razões de Prevalência e Intervalos de Confiança. Resultados: Foram avaliados 2.014 universitários, dos quais 22.4% reportaram medo odontológico. Aqueles que reportaram medo odontológico apresentaram uma maior prevalência de não terem ido ao dentista no último ano e, entre os que consultaram, a visita ter sido motivada por dor/problema. Adicionalmente, ter medo aumentou a presença de cárie, dor dentária e autorrelato da saúde bucal negativa. Discussão: Os achados sugerem a presença do ciclo vicioso do medo nesta população de universitários do sul do Brasil. Conclusão: Evidenciou-se a associação entre a presença de medo odontológico e a menor procura por atendimento odontológico, a presença de cárie dentária, dor dentária e saúde bucal autorreportada negativa, corroborando com a teoria do ciclo do medo.

Aim: To evaluate the presence of dental fear among Brazilian undergraduate students and to observe whether the cycle of dental fear theory applies to this population. Materials and methods: A cross-sectional study were conducted with first year students of the Federal University of Pelotas, Brazil, in 2016. Sociodemographic data, dental fear, as well as the use of dental services and perception of caries and dental pain were collected through a self-administered questionnaire. The exposure was dental fear, and the outcomes included dental visit pattern, experience of dental caries and dental fear and self-rated oral health (SROH). Sociodemographic characteristics were included as aconfounding factor. To test the association between dental fear and the outcomes, Poisson regression models with robust variance were used, to estimate Prevalence Rations and Confidence Intervals. Results: 2,014 undergraduate students were evaluated and 22.4% of them reported dental fear. Those who reported dental fear had a higher prevalence of not visiting the dentist in the last year and, among those who visited, to have had only a pain/problem-oriented visit. Additionally, having fear increased the presence of dental caries, dental pain and negative SROH. Discussion: Our findings suggest the presence of the vicious cycle of dental fear in this population of undergraduate students in southern Brazil. Conclusion: This study provided evidence on the association between dental fear and the lower frequency of dental visit, dental caries, dental pain experience and negative SROH, corroborating with the cycle of dental fear theory.

Relação da condição de cárie da criança com experiência de cárie da mãe / Relationship between the child's caries status and the mother's caries experience

Objetivo: verificar a relação da condição de cárie da criança com a experiência autopercebida de cárie da mãe através de um estudo observacional transversal. Métodos: O estudo foi realizado na Faculdade de Odontologia da Universidade Federal de Pelotas com crianças entre 8 e 11 anos e suas mães. A amostra contou com 105 pares mãe-filho. Os responsáveis responderam um questionário relacionado à situação socioeconômica e demográfica, a mãe respondeu sobre sua saúde bucal: experiência de cárie (restauração ou dente cariado e perda dentária por cárie). Nas crianças os desfechos foram avaliados através de exame clínico com a soma de dentes decíduos e permanentes cariados, perdidos e obturados (ceod/CPOD) e para severidade de cárie foi utilizado Significant Caries Index (SiC), ceod/CPOD≥3. Para testar a associação entre as variáveis relacionadas à mãe e o desfecho severidade de cárie foi realizado o teste Qui-quadrado, para média de cárie na criança (ceod/CPOD) foi utilizado o Teste Mann-Whitney. Resultados: Com relação à severidade de cárie não foi encontrada associação estatisticamente significante. A média do ceod/CPOD foi quase três vezes maior nas crianças cujas mães relataram que haviam tido ou estavam com algum dente cariado ou restaurado em função da cárie em comparação àquelas que não relataram esta experiência. As mães mais jovens apresentaram filhos com maior média de cárie do que as mães mais velhas. Conclusão: Entre as crianças atendidas neste serviço existe uma relação de uma maior média de cárie nas crianças com cujas mães tem ou tiveram experiência de cárie e mais jovens.(AU)

Objective: to verify the relationship between the child's caries condition and the mother's self-perceived caries experience through a cross-sectional observational study. Methods: The study was carried out at the Faculty of Dentistry of the Federal University of Pelotas with children between 8 and 11 years old and their mothers. The sample had 105 mother-child pairs. The guardians answered a questionnaire related to the socioeconomic and demographic situation, the mother answered about her oral health: caries experience (restoration or decayed tooth and tooth loss due to caries). In children, the outcomes were evaluated through clinical examination with the sum of decayed, missing and filled deciduous and permanent teeth (DMFT/DMFT) and for caries severity we used the Significant Caries Index (SiC), DMFT/DMFT≥3. To test the association between the variables related to the mother and the outcome of caries severity, the Chi-square test was performed, for mean caries in children (dmft/DMFT) the Mann-Whitney Test was used. Results: Regarding caries severity, no statistically significant association was found. The mean dmft/DMFT was almost three times higher in children whose mothers reported that they had had or had a decayed or restored tooth due to caries compared to those who did not report this experience. Younger mothers had children with a higher average of caries than older mothers. Conclusion: Among the children assisted in this service, there is a relation of a higher average of caries in children whose mothers have or had caries experience and younger.(AU)

Discriminant validity of the CAST instrument compared to the dmf index in the deciduous dentition: a cross sectional study.

This study aimed to assess the discriminant validity of the Caries Assessment Spectrum and Treatment (CAST) at different thresholds, compared with the Decayed, Missing, and Filled Teeth Index (dmf) instrument, to discriminate caries risk factors. A cross-sectional study was conducted including children aged 2-5 years from preschools in Southern Brazil. Parents answered a questionnaire, and children were clinically examined using the CAST instrument and, in the following weeks, using the dmf index. Two caries thresholds were adopted for CAST: caries in dentin (CAST4-7/CAST2,4-8) and enamel caries (CAST3-7/CAST2-8). Poisson regression was used in the analysis (p < 0.05). A total of 200 children were included. The prevalence of caries was 47.0% with dmf, 42.5% with CAST4-7, and 77.5% with CAST3-7. When the outcome was caries prevalence, CAST4-7 discriminated between sexes, household crowding, and dental pain, and CAST3-7 discriminated age and family income, while the dmf was associated with dental pain. When experience of caries was the outcome, all the criteria discriminated between sexes, age, family income, household overcrowding, visible dental plaque, and dental pain, while dmf and CAST2-8 also discriminated maternal schooling. The CAST discriminated caries risk factors similar to the dmf index when caries experience was the outcome. When prevalence was considered, CAST was able to discriminate for more individual characteristics than dmf.

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)

Prevention and Management of Dental Trauma in Primary Teeth in the Context of the COVID-19: A Critical Literature Review

ABSTRACT Objective: To evaluate and discuss the prevention and management of dental trauma in primary teeth during the COVID-19 pandemic. Material and Methods: Critic literature review, searching electronic databases and Google for articles and guidelines published in English that described prevention and management of dental trauma in primary dentition during the pandemic of COVID-19. Results: 5 publications regarding management and 1 leaflet about prevention for parents were identified. Urgent care is required when the child presents tooth fracture resulting in pain or causing soft tissue trauma and luxation affecting bite. Avulsed teeth should not be replanted and advice and self-help may be sufficient in some situations. Instructions about soft diet and hygiene must be provided. Remote consults are recommended for non-urgent situations and during follow-up to evaluate the presence of sequelae. Aerosol generating procedures should be avoided and, in cases of poor prognosis, extraction is recommended to prevent recurring visits to the dental office. Conclusion: During COVID-19 pandemic, remote consults should be recommended to evaluate traumatic dental injuries in primary dentition. Follow-up should not be neglected and may be performed through remote consultation.

Discriminant validity of the CAST instrument compared to the dmf index in the deciduous dentition: a cross sectional study

Abstract This study aimed to assess the discriminant validity of the Caries Assessment Spectrum and Treatment (CAST) at different thresholds, compared with the Decayed, Missing, and Filled Teeth Index (dmf) instrument, to discriminate caries risk factors. A cross-sectional study was conducted including children aged 2-5 years from preschools in Southern Brazil. Parents answered a questionnaire, and children were clinically examined using the CAST instrument and, in the following weeks, using the dmf index. Two caries thresholds were adopted for CAST: caries in dentin (CAST4-7/CAST2,4-8) and enamel caries (CAST3-7/CAST2-8). Poisson regression was used in the analysis (p < 0.05). A total of 200 children were included. The prevalence of caries was 47.0% with dmf, 42.5% with CAST4-7, and 77.5% with CAST3-7. When the outcome was caries prevalence, CAST4-7 discriminated between sexes, household crowding, and dental pain, and CAST3-7 discriminated age and family income, while the dmf was associated with dental pain. When experience of caries was the outcome, all the criteria discriminated between sexes, age, family income, household overcrowding, visible dental plaque, and dental pain, while dmf and CAST2-8 also discriminated maternal schooling. The CAST discriminated caries risk factors similar to the dmf index when caries experience was the outcome. When prevalence was considered, CAST was able to discriminate for more individual characteristics than dmf.

Crown-Root Fractures in Primary Teeth: A Case Series Study of 28 Cases.

Crown-root fractures in primary teeth are rare, with a wide variation of patterns that make diagnosis and treatment difficult. The aim of this study was to present a case series of crown-root fractures in primary teeth of children who attended a reference center. The study followed 28 cases of crown-root fractures in 26 children, representing 4% of the total number of attendees over 11 years of reference service at the Universidade Federal de Pelotas, Pelotas, Brazil. In most cases, the maxillary central incisors (85.7%) were involved. In the crown, 57.1% of the cases had a simple line of fracture, and 42.9% had multiple lines. Simple lines predominated in the root (89.3%). In cases with simple fracture lines in the crown, 37.6% underwent a total extraction, 31.2% required a partial extraction and 31.2% underwent pulpectomy. In most teeth with multiple lines of fractures in the crown, total extraction was performed (91.7%) All cases were followed-up until the eruption of the permanent successor tooth, and all patients had favorable outcomes.
