ABSTRACT Objective: To assess the relationship between celiac disease and the prevalence of dental caries in children and adolescents and also evaluate if dental enamel defects in celiac children predispose to dental caries. Material and Methods: Searches were performed in the following databases: PubMed, Scopus, Cochrane Library, Latin American and Caribbean Literature on Health Sciences, and OpenGrey. The risk of bias was assessed using the Newcastle-Ottawa Scale. DMFT/dmft and DMFS/dmfs data of observational studies that compared the prevalence of caries between children and adolescents with celiac disease and healthy individuals. Meta-analysis was performed using a random effects model. Heterogeneity between studies was estimated using Cochran’s Q test, and inconsistency was measured using I2 statistics. Results: Of the 121 studies retrieved, 17 were selected, and 12 were included in the meta-analysis. The prevalence of caries in the primary dentition (dmft) did not differ between celiac patients and controls [SMD = -0.35; 95% CI (-0.83; 0.13); p = 0,15; I2 = 89%]. There was also no difference in the prevalence of caries in permanent teeth (DMFT) between groups [SMD = -0.44; 95% CI (-1.02; 0.14); p = 0.14; I2 = 95%]. Conclusion: Celiac disease is not a determinant factor in the development of dental caries in children and adolescents compared to the control group.

Abstract Objective: To identify the commercially available toothpastes intended for children and their total soluble fluoride concentrations (TSF). Material and Methods: Twelve brands of toothpastes intended for children marketed in supermarkets and pharmacies were found and analyzed: Bitufo®; Colgate Smile®; Lilica Ripilica®; Even Baby®; Turma da Mônica Baby®; Loney Tunes®; Loney Tunes Baby®; Malvatrikds Baby®; Oral B Stages®; Sanifil Kids®; Tandy®; Tra-lá-lá Baby®. Duplicate samples of each toothpaste were weighed (+/- 90 to 110 mg) and diluted in 10 mL of distilled water under stirring. To evaluate soluble fluoride, duplicate aliquots of supernatant suspensions were evaluated on specific ion fluoride electrode calibrated with fluoride standard solutions and results expressed in ppm F according to established protocol. Results: According to information provided by manufacturers, 5 non-fluoridated toothpastes, 3 toothpastes with less than 1000 ppm F and 4 toothpastes with conventional fluoride concentration (1100 ppm F) were identified. After analysis of soluble fluoride of fluoridated toothpastes, only 02 presented TSF concentration equal to or greater than 1000 ppm F. The TSF concentration (mean ± SD) for all samples ranged from 8.2 ± 0.1 to 1065.9 ± 24.7 ppm F. Conclusion: Few toothpastes intended for children presented soluble fluoride concentrations capable of preventing dental caries. Additionally, regulatory measures need to be implemented for the marketing of toothpastes intended for children with at least 1000 ppm of soluble fluoride, especially in locations without other sources of fluoride (fluoridated water) for the population.

RESUMO Objetivo: Analisar as condições de saúde bucal e fatores de risco de cárie de pacientes com doença falciforme. Métodos: A pesquisa observacional e transversal foi realizada na Associação de Pessoas com Hemoglobinopatias de Alagoas situada na cidade de Maceió-AL. Amostra composta por 43 pacientes incluídos por amostragem censitária. Foram utilizados os índices de cárie ICDAS/CPOD/ceod e de higiene oral simplificado, testes de fluxo salivar e capacidade tampão. Os pacientes foram entrevistados para a verificação do nível de conhecimento sobre higiene bucal e dieta. Foram aplicados os testes de correlação de Spearman e ANOVA (p<0,05). Resultados: O CPOD médio foi de 15,49±4,43, higiene oral regular (IHOS=2,22±0,18), fluxo salivar médio de 0,92±0,26 e capacidade tampão média de 4,60±0,32. Existiu correlação entre o fluxo salivar e capacidade tampão (p= 0,009). Os pacientes com maiores prevalências de cárie, nas faixas etárias de 6 a 12 anos e 20 a 26 anos, possuíam os mais baixos valores de capacidade tampão (p= 0,04). A entrevista mostrou que 58% não utilizavam fio dental, 88% lanchavam alimentos cariogênicos, 100% relataram nunca ter recebido orientações do cirurgião dentista sobre o potencial cariogênico dos alimentos e 60% relataram que utilizavam medicamentos redutores de salivação (Tramal® e morfina) durante as crises álgicas. Conclusão: Os pacientes apresentaram uma prevalência de cárie muito alta, com a predominância de dentes cariados. Os parâmetros salivares analisados e o nível de conhecimento, sobre higiene bucal e dieta cariogênica apresentados, mostraram que pacientes com doença falciforme pertencem a um grupo de risco de desenvolvimento de cárie dentária.

ABSTRACT Objective: To analyze the oral health conditions and risk factors for caries in patients with sickle cell disease. Methods: An observational, cross-sectional study was conducted in the clinic of the Association of Persons with Hemoglobinopathies of Alagoas, in the city of Maceió-AL, Brazil. The sample composed of 43 patients were included by census sampling. The ICDAS/DMFT/dmf-t caries indices were used, and simplified oral hygiene, salivary flow and buffer capacity tests were performed. Patients were interviewed to check their level of knowledge about oral hygiene and diet. Spearman correlation and ANOVA statistical tests were applied (p<0.05). Results: The mean DMFT was 15.49±4.43; oral hygiene regular (IHOS=2.22±0.18); mean salivary flow 0.92±0.26, and mean buffer capacity 4.60±0.32. Correlation was found between salivary flow and buffer capacity (p = 0.009). Patients with the highest caries prevalence, in the age-ranges 6 to 12, and 20 to 26 years, had the lowest buffer capacity values (p = 0.04). Interviews showed that 58% did not use dental floss, 88% consumed cariogenic snacks, 100% reported never having received guidance from dentists about the cariogenic potential of foods and 60% reported the use of anticholinergic medications to reduce drooling (Tramal® and morphine) during pain crises. Conclusion: These patients presented extremely high caries prevalence, with predominance of carious teeth. The salivary parameters analyzed and level of knowledge about oral hygiene and cariogenic diet presented, showed that patients with sickle cell disease belonged to a group with risk for development of dental caries.

Resumo Introdução pacientes estão sendo submetidos ao clareamento durante tratamento ortodôntico com finalidade estética ou para antecipar a troca de restaurações após finalização do tratamento ortodôntico. Objetivo avaliar a efetividade do clareamento dentário sob braquete ortodôntico fixado com diferentes materiais. Material e método cem blocos de esmalte bovino foram divididos em dois grupos, clareamento de consultório e clareamento caseiro. O de clareamento de consultório foi subdividido em cinco (n=10): HP (controle – sem braquetes); SA(t) – braquetes fixados com Transbond XT, sem clareamento; SA(fm) – braquetes fixados com Fill Magic Ortodôntico, sem clareamento; HP(t) – braquetes fixados com Transbond XT submetidos ao clareamento e HP(fm) – braquetes fixados com Fill Magic Ortodôntico submetidos ao clareamento. O clareamento caseiro seguiu a mesma divisão descrita para o clareamento de consultório substituindo-se o agente clareador. Foram realizadas avaliações da cor através do espectrofotômetro nos tempos: 1) antes do manchamento (baseline); 2) após o manchamento; 3) após fixação dos braquetes e procedimentos clareadores. Os dados foram submetidos à ANOVA e diferenças analisadas através do teste de Tukey (p˂0,05). Resultado Para os dois tipos de clareamento o grupo controle teve ação clareadora efetiva. Grupos fixados com Transbond XT apresentaram maior potencial clareador dentre os grupos que apresentaram acessório ortodôntico, mas com ação clareadora diferente do controle positivo. Grupos fixados com Fill Magic Ortodôntico não apresentaram ação clareadora, assemelhando-se aos grupos controle negativo (saliva artificial). Conclusão o braquete ortodôntico prejudicou a efetividade do tratamento clareador caseiro e de consultório, independente da resina utilizada para a fixação.

Abstract Introduction patients have been submitted to tooth bleaching during orthodontic treatment for aesthetic purposes or to anticipate the replacement of restorations after completion of the treatment. Objective to evaluate the effectiveness of tooth bleaching under orthodontic brackets bonded with different materials. Material and method a hundred bovine enamel blocks were divided into two groups, at-home and in-office tooth bleaching. In-office bleaching was subdivided into five groups (n = 10): HP (control - without brackets); SA(t) - brackets bonded with Transbond XT, without bleaching; SA(fm) - brackets bonded with Orthodontic Fill Magic, without bleaching; HP(t) - brackets bonded with Transbond XT subjected to bleaching; and HP(fm) - brackets bonded with Orthodontic Fill Magic subjected to bleaching. At-home bleaching followed the same treatments, only replacing the bleaching agent. Spectrophotometric assessment was used for tooth color determination at three moments: 1) before staining (baseline); 2) after staining; 3) after bonding the brackets and bleaching procedures. Data were submitted to ANOVA and analyzed by Tukey's test (p < 0.05). Result For both types of bleaching, the control group had an effective bleaching action. Groups using Transbond XT presented greater bleaching potential among the groups with orthodontic accessory, but the bleaching action differed from the positive control. Groups using Orthodontic Fill Magic presented no bleaching action, resembling the negative control groups (artificial saliva). Conclusion the orthodontic bracket impaired the effectiveness of the at-home and in-office bleaching treatment, regardless of the resin used for bonding.

RESUMO JUSTIFICATIVA E OBJETIVOS: A hipersensibilidade dentinária cervical é uma condição clínica rotineira na atualidade que decorre da exposição da dentina ao meio bucal e sensibilidade causada após a ingestão de alimentos frios, doces ou ácidos, o que ocasiona dor localizada, aguda e de curta duração. O objetivo deste estudo foi analisar clinicamente a eficácia de dois tratamentos utilizados na redução da hipersensibilidade dentinária cervical, bem como a duração dos seus efeitos. MÉTODOS: O estudo foi desenvolvido como um ensaio clínico duplamente encoberto comparativo, onde foram selecionados 14 pacientes com hipersensibilidade dentinária cervical, atendidos na Clínica Escola de Odontologia do Centro Universitário Cesmac. Os participantes foram divididos em dois grupos com 7 integrantes cada. O primeiro grupo foi submetido ao tratamento com o dessensibilizante à base de nitrato de potássio a 5% (Nano P®-FGM) e no segundo grupo foi aplicado o verniz fluoretado (Fluorniz®-SS White). Em ambos os tratamentos foram seguidas as instruções dos fabricantes. RESULTADOS: As avaliações do quadro clínico ocorreram aos 7, 14, 21 dias e 1 mês. Após a análise estatística dos resultados pôde-se concluir que ambos os produtos apresentaram redução clínica inicial no quadro de hipersensibilidade dentinária cervical nos elementos dentais pesquisados após as suas aplicações e que o efeito do dessensibilizante à base de nitrato de potássio foi mais duradouro do que o do verniz fluoretado. CONCLUSÃO: O efeito de dessensibilização com base de nitrato de potássio foi mais durável do que o do verniz fluoretado.

ABSTRACT BACKGROUND AND OBJECTIVES: Cervical dentin hypersensitivity is a routine clinical condition caused by dentin exposure to the oral environment and sensitivity caused by the ingestion of cold, sweet or sour foods, which induces localized, acute and brief pain. This study aimed at clinically evaluating the efficacy of two treatments to improve cervical dentin hypersensitivity, as well as the duration of their effects. METHODS: The study was developed as a clinical, doubleblind and comparative study where 14 patients with cervical dentin hypersensitivity treated in the Clinic School of Dentistry of the University Center Cesmac were selected. Participants were divided in two groups of seven individuals. The first group was submitted to treatment with 5% potassium nitrate desensitizing (Nano P®-FGM) and the second group received fluoride varnish applications (Fluorniz®-SS White). Both treatments have followed manufacturers’ instructions. RESULTS: Clinical evaluations were performed 7, 14, 21 days and 1 month after treatment. After statistical analysis of results, it was possible to conclude that products have improved initial cervical dentin hypersensitivity in studied dental elements after their applications and that the desensitizing effect of potassium nitrate was longer lasting as compared to fluoride varnish. CONCLUSION: Potassium nitrate desensitizing effect was longer lasting as compared to fluoride varnish.
