Purpose: To determine the prevalence of developmental defects of the enamel (DDE) in premolars whose infected predecessors were submitted to pulp therapy with antibiotic paste or extractions due to pulp necrosis.Materials and Methods: A cross-sectional study with a consecutive sample consisting of children and adolescents who presented with fully erupted premolars, was evaluated. Data were collected by dental examinations, in which the modified DDE index was applied. Dental records were evaluated and three groups of premolars were determined according to the clinical history of predecessors: GCTZ: with pulp necrosis and treated with CTZ (chloramphenicol, tetracycline, zinc oxide and eugenol) paste; GE: with pulp necrosis and treated by extraction; GH: healthy and physiologically exfoliated. Descriptive analysis and a logistic regression (p <0.05) were performed.Results: The study included 1017 premolars, DDE was present in 22.5%. Premolars belonging to the GE group presented higher odds of DDE (odds ratio (OR) = 3.52, 95% CI:2.29-5.40) than those of GCTZ group (OR = 2.43, 95% CI:1.51-3.91) and GH group (p <0.01). Enamel defects were more frequent in maxillary premolars (OR = 3.22, 95% CI:1.65-6.27, OR = 3.39, 95% CI:1.67-6.90, OR = 2.90, 95% CI:1.48-5.66 and OR = 3.10, 95% CI:1.54-6.23).Conclusions: The prevalence of enamel defects was higher in premolars whose predecessors were removed because of necrosis, followed by those treated with CTZ paste and those that were healthy by the time exfoliation occurred.

Objective: To determine the impact of water fluoridation on the prevalence and severity of dental caries and fluorosis in individuals aged 17–20 years exposed to fluoride toothpaste. Methods: The study population consisted of 660 students from public schools, residents of areas supplied with fluoridated water (exposed group) or not (not exposed group). Students from both groups had access to fluoride toothpaste throughout life. A questionnaire about socioeconomic demographic aspects, conditions related to access and exposure to fluoridated water, and habits related to oral health was applied. Dental caries was measured by the DMFT index and dental fluorosis by the TF index. The chi‐square test, t test, and subsequently logistic regression were applied for data analysis. Results: Caries experience (DMFT≠0) was significantly higher in students from areas not exposed to fluoridated water, after adjustments to clinical conditions, demographic socioeconomic profile, and hygiene habits. The DMFT mean (±SD) was significantly higher in students from areas not exposed to fluoridated water than exposed (3.83 [±3.28] and 2.48 [±2.71] respectively). The prevalence of very mild/mild and moderate fluorosis was 41.1% and 21% for students either exposed to fluoridated water or not, respectively. Conclusion: Exposure to fluoridated water was associated with a lower prevalence and severity of tooth decay, in spite of the use of fluoridated toothpaste. The prevalence of dental fluorosis at all levels was higher in fluoridated areas, however, in both groups, there were few cases with esthetic implications. [ABSTRACT FROM AUTHOR]

Background: Hypomineralized second primary molar (HSPM) is a developmental enamel defect that represents a caries‐risk factor. There are few studies about HSPM epidemiology in representative populations. Aim: To determine the prevalence and factors associated with HSPM in pre‐schoolers. Design: This is a cross‐sectional population‐based study of 5‐year‐old pre‐schoolers from Teresina, Brazil. The sample was randomly selected and stratified by geographic region of the city, type of school (public and private), and sex of the pre‐schoolers (n = 811). Sociodemographic status and pre‐, peri‐, and post‐natal conditions were collected by structured questionnaires. Two calibrated examiners diagnosed HSPM using the criteria of the European Academy of Paediatric Dentistry for molar‐incisor hypomineralization. Severity, colour, location, and extent of lesions were also evaluated. Descriptive analysis of the data and a Poisson regression analysis were performed (P <.05). Results: The prevalence of HSPM was 14.9. Demarcated opacities (75.6%) and white/cream colour were the most prevalent (71.4%). Pre‐term pre‐schoolers had 66% (PR = 1.66, 95% CI = 1.07‐2.58), and those who reported asthma in the first year of life had 69% (PR = 1.69, 95% CI = 1.01‐2.85) higher prevalence of HSPM. Conclusions: Pre‐term birth and reported asthma in the first year of life were associated with HSPM. The prevalence of HSPM in pre‐schoolers aged 5 years old in Teresina was high.

Atraumatic Restorative Treatment (ART) is one of the strategies used to control dental caries; it involves hand instruments for removal of carious tissue, and restorations using high-viscosity Glass Ionomer Cement (GIC). The present controlled clinical trial aimed to evaluate the performance of low-cost GIC indicated for ART in primary teeth, compared with high-viscosity GIC, after one year of follow-up. Two-to six-year-old children with dentin caries lesions on one or two surfaces of anterior and posterior teeth were selected. The children were randomly assigned to 2 groups according to the restorative material used: G1 (control) -- Ketac Molar®; G2 (experimental) -- Vitro Molar®. Treatments were performed in a school setting, following the guidelines of the ART. A total of 728 restorations were performed in 243 children. Descriptive analysis and Poisson regression were applied, with a significance level of p < 0.05. After 12 months, 559 (76.8%) restorations were re-evaluated. The success rate was evaluated by the prevalence ratio (PR), associated with restorations performed in primary second molars ( PR = 1 .21; 9 5%CI = 1 .03-1.42), a nd w ith s mall ( PR = 1 .35; 95%CI = 1 .14-1.60) o r m edium c avities ( PR = 1 .29; 9 5%CI = 1 .08-1.55), using Ketac Molar® material (PR= 1.07; 95%CI = 1.01-1.15), considering p < 0.05. Small or medium restorations in primary second molars performed with high-viscosity GIC (Ketac Molar®) were more successful than restorations performed with low-cost GIC indicated for ART.

Purpose: To determine the prevalence of molar-incisor hypomineralization (MIH) in children and possible factors associated with this disorder.Methods: This was a cross-sectional observational study of 594 11- to 14-year-olds from Teresina, Piauí, Brazil. The diagnosis of MIH was made based on criteria set by the European Academy of Pediatric Dentistry. To investigate possible associated factors, mothers completed a questionnaire. A descriptive analysis of the data, chi-square, Mann-Whitney, and Fisher tests and Poisson regression (PR) were performed.Results: The prevalence of MIH was 18.4 percent (95 percent confidence interval [CI] equals 15.20 to 21.50). The maxillary molars were the teeth most affected by MIH (36.1 percent). MIH patients showed a higher number of mean DMF-T (PR equals 2.18; 95 percent CI equals 1.46 to 2.85) than those not affected by the condition. There was an association between MIH and preterm birth (PR equals 1.76; 95 percent CI equals 1.22 to 2.12) and between MIH and respiratory distress at birth (PR equals 1.83; 95 percent CI equals 1.25 to 2.18).Conclusions: The prevalence of MIH in schoolchildren was 18.4 percent. Those with MIH had a greater mean DMF-T than those without MIH. Preterm birth and respiratory distress were associated with MIH. [ABSTRACT FROM AUTHOR]

Amelogenesis imperfecta (AI) is a tooth disorder characterized by the abnormal development of the enamel in response to mutations in the genes involved in amelogenesis. The objective of this article is to present the clinical case of a child with AI in the primary dentition phase. A 4-year-old boy was presented to a clinic by his mother, who complained that her son's smile esthetics were compromised by "weak and yellow teeth." All the teeth showed yellowish discoloration as well as crumbling or missing enamel. Due to the absence of carious lesions and the presence of normal pulp in the teeth, it was decided to restore the dentition with indirect crowns of ceramic-optimized polymer, also known as ceromer. No preparations were performed on the teeth. For this patient, indirect ceromer restorations presented a good treatment option for the rehabilitation of primary teeth affected by AI.

Introdução e Objetivos: Hipomineralização molar-incisivo (MIH) corresponde a defeito qualitativo do esmalte dentário que afeta primeiros molares permanentes frequentemente em associação com incisivos permanentes. A prevalência desta condição tem sido bastante variável entre as populações com valores entre 2,8% a 44% e frequência global estimada em 14,2%. Indivíduos com MIH têm 2.1 a 4.6 mais chances de desenvolver cárie dentária. A hipomineralização molar-incisivo é um problema de saúde pública silencioso, com encargo socioecônomico substancial e que afeta a qualidade de vida dos que a possuem, entretanto ela é negligenciada, possivelmente pelo pouco conhecimento dos cirurgiões-dentistas sobre a condição. O diagnóstico precoce de dentes com MIH possibilita a adoção de condutas preventivas a fim de evitar desintegração pós-eruptiva do esmalte hipomineralizado, diminuindo a possibilidade de desenvolvimento de lesões cariosas. Esse estudo transversal teve como objetivo avaliar a percepção dos cirurgiões-dentistas de Teresina-Piauí-Brasil sobre MIH. Materiais e Métodos: A população do estudo foi composta por cirurgiões-dentistas (CD) inscritos no CRO-PI, que exercem a profissão no município de Teresina-PI. Para o cálculo da amostra foi utilizado o software Epi-info 7.0, no módulo STATCALC. A amostra ideal para o desenvolvimento deste estudo seria de 314 CD. Foi aplicado questionário semiestruturado, segundo o estudo de CROMBIE et al. (2008) e disponibilizadas fotografias de dentes com MIH. A coleta de dados foi realizada por email, por carta ou por contato pessoal, no período de outubro de 2015 a março de 2016. Para a análise dos dados utilizou-se o programa SPSS® versão 18.0. Resultados: A amostra final foi composta por 324 profissionais, sendo 192 do sexo masculino e 132 do feminino. O diagnóstico de MIH foi relatado por 71 cirurgiões-dentistas (21,91%). Outros diagnósticos citados incluíram Hipoplasia (n=83), Fluorose (n=69) e amelogênese imperfeita (n=45). O conhecimento sobre MIH esteve associado ao tempo de formação (p=0,015), local de exercício da profissão (p=0,022), instituição de graduação (p=0,001), maior titulação (p=0,001) e informações prévias (p=0,001). Observou-se maior chance de acerto do diagnóstico para cirurgiões-dentistas formados há até cinco anos (OR= 10,85, IC95% 3,14-37,41) e egressos de faculdades públicas (OR= 55,03, IC95% 11,29-68,07). Traumas e deficiências nutricionais foram os fatores etiológicos mais citados. Quanto ao tratamento indicado, os cirurgiões dentistas indicaram com maior frequência o acompanhamento do paciente, restaurações de resina composta e fluorterapia. Conclusão: Concluiu-se que a MIH ainda é um tema desconhecido pelos cirurgiões-dentistas. Dessa forma é importante o estimulo à capacitação e à atualização constante para que os profissionais realizem o melhor tratamento para os pacientes afetados. [ABSTRACT FROM AUTHOR]

Introducao e objetivos: A Hipomineralizacao molar-incisivo (MIH) constitui defeito qualitativo do esmalte dentario que acomete 1 a 4 primeiros molares permanentes, podendo afetar incisivos permanentes. A condicao representa problema de saude publica por estar relacionada a carie dental e sua etiologia permanece inconclusiva. Comunidades quilombolas sao grupos etnico-raciais que vivem em situacao de vulnerabilidade social, ma nutricao e dificuldade de acesso a servicos de saude, fatores que podem predispor ao desenvolvimento da MIH. Este estudo observacional transversal teve por objetivo determinar a prevalencia e os fatores associados a MIH em criancas e adolescentes quilombolas rurais do nordeste brasileiro. Materiais e metodos: A amostra foi constituida por criancas e adolescentes residentes na comunidade quilombola rural Lagoas em Sao Raimundo Nonato, Piaui (populacao censitaria). Foram incluidos os individuos com idade de 8 a 14 anos, que possuiam as coroas dos quatro primeiros molares permanentes totalmente visiveis. Foram excluidos do estudo criancas e adolescentes que apresentaram fluorose dentaria em grau moderado/avancado, hipoplasia do esmalte ou amelogenese imperfeita, bem como os individuos que se encontravam em tratamento ortodontico fixo no momento da avaliacao, condicoes que dificultariam o diagnostico da condicao. Foram coletados dados sociodemograficos e relacionados a saude pre, peri e pos-natal e realizado exame clinico dentario, por quatro examinadores previamente treinados e calibrados (Kappa.0,8) para diagnostico da MIH. Os dados foram digitados duplamente e analisados pelo programa StatisticalPackage for the Social Science (SPSS), versao 20.0. Foram realizadas analise descritiva dos dados e regressao de Poisson com variancia robusta. A magnitude da associacao foi avaliada por razao de prevalencia bruta e ajustada (RP), e intervalos de confianca de 95% (IC 95%). Resultados: A amostra foi constituida por 251 criancas e adolescentes que atenderam aos criterios de inclusao da pesquisa (populacao censitaria). A prevalencia de MIH foi de 46,6%. No modelo final, a presenca de MIH esteve associada a diabetes gestacional (RP = 2,49; IC95% 2,08-2,99; p<0,001) e a sofrimento fetal agudo (RP = 1,39; IC95% 1,04-1,86; p=0,025). Conclusao: Conclui-se que a prevalencia de MIH na populacao estudada foi alta e associada com diabetes gestacional e sofrimento fetal agudo. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this study was to evaluate the prevalence of dental caries, toothbrushing habits, fluoride intake, and factors associated with the use of toothpaste in Brazilian children according to socioeconomic status (SES).Methods: A cross-sectional observational study was conducted with 148 three- to four-year-olds of both low and high socioeconomic status. Data collection consisted of administering a questionnaire to guardians, brushing to determine fluoride intake, and examining the children's teeth to evaluate dental caries.Results: In this study, 42 percent of children from high SES and 2.7 percent of children from low SES used toothpaste without fluoride or with a concentration below 1,000 ppm F. Fluoride intake was associated with SES, frequency of brushing, the amount of toothpaste used, and the concentration of fluoride present in toothpastes (P<0.05). Low SES children had a higher fluoride intake during brushing (0.045 mg F/kg body weight/day), compared to high SES children (0.023 mg F/kg body weight/day). Unlike low SES children (68.9 percent), all high SES children were caries free.Conclusions: A lower socioeconomic status was associated with a higher prevalence of dental caries and a higher intake of fluoride from toothpaste.

Severe dentoalveolar ankylosis is an etiological factor for malocclusion. When infraocclusion occurs early, it progresses with time, leading to severe consequences in young children because of compensatory supra-eruption of the antagonist tooth and mesialization of adjacent teeth. Early diagnosis allows for interception of the problem and may prevent orthodontic treatment. he purpose of this manuscript is to report two cases of infraocclusion of primary mandibular second molars that were diagnosed early and were treated with composite resin crowns. he use of indirect composite restorations for ankylosed teeth is a good option for primary teeth with a moderate/severe degree of ankylosis.

Purpose: This study's purpose was to investigate the prevalence of dental fluorosis in children, whose parents had participated in an oral health program when the children were between zero and three years old, residing in a city with fluoridated water. Methods: Group 1 consisted of 128 eight- to 12-year-olds whose parents had visited a program on at least five occasions when the children were zero to three years old and received education about tooth-brushing and the proper use of fluoridated toothpaste in this young age group. The prevalence of dental fluorosis in the permanent maxillary incisors, using the Thylstrup-Fejerskov index, in Group 1 was compared to that of an age-matched group of children (n=128) whose parents had not participated in the program (Group 2). Results: Group 1 mothers reported higher education levels (P<.05). Group 1 children had a significantly lower prevalence (~42 percent) and severity (P<.05) of dental fluorosis than those in the control group (~61 percent). Conclusion: Children whose parents participated in a dental program that included counselling on the proper amount of fluoridated toothpaste when their children were between zero and three years old presented less frequently with dental fluorosis than a control group when examined at eight to 12 years old.
