ABSTRACT
BACKGROUND: Important evidence has been constantly produced and needs to be converted into practice. Professional consumption of such evidence may be a barrier to its implementation. Then, effective implementation of evidence-based interventions in clinical practice leans on the understanding of how professionals value attributes when choosing between options for dental care, permitting to guide this implementation process by maximizing strengthens and minimizing barriers related to that. METHODS: This is part of a broader project investigating the potential of incorporating scientific evidence into clinical practice and public policy recommendations and guidelines, identifying strengths and barriers in such an implementation process. The present research protocol comprises a Discrete Choice Experiment (DCE) from the Brazilian oral health professionals' perspective, aiming to assess how different factors are associated with professional decision-making in dental care, including the role of scientific evidence. Different choice sets will be developed, either focusing on understanding the role of scientific evidence in the professional decision-making process or on understanding specific attributes associated with different interventions recently tested in randomized clinical trials and available as newly produced scientific evidence to be used in clinical practice. DISCUSSION: Translating research into practice usually requires time and effort. Shortening this process may be useful for faster incorporation into clinical practice and beneficial to the population. Understanding the context and professionals' decision-making preferences is crucial to designing more effective implementation and/or educational initiatives. Ultimately, we expect to design an efficient implementation strategy that overcomes threats and potential opportunities identified during the DCEs, creating a customized structure for dental professionals.

The aim of this study was to report the clinical findings and the screening of mutations of amelogenin gene of a 7-year-old boy with amelogenesis imperfecta (AI). The genomic DNA was extracted from saliva of patient and his family, followed by PCR and direct DNA sequencing. The c.261C>T mutation was found in samples of mother, father, and brother, but the mutation was not found in the sequence of the patient. This mutation is a silent mutation and a single-nucleotide polymorphism (rs2106416). Thus, it is suggested that the mutation found was not related to the clinical presence of AI. Further research is necessary to examine larger number of patients and genes related to AI.

O objetivo deste estudo foi investigar o efeito da Terapia Fotodinâmica antimicrobiana (TFDa) sobre o Enterococcus faecalis (E. faecalis), in vitro, utilizando a clorofila (CL) como agente fotossensibilizador (FS) e o diodo emissor de luz (LED) como fonte de luz. A cultura pura de E. faecalis foi ativada em caldo de BHI a 37oC por 24h. O cultivo do microrganismo foi centrifugado a 3000rpm por 15min, e o pellet re-suspenso em 0,85% de solução salina. As concentrações da bactéria foram ajustadas para 107UFC mL-1 (unidades formadoras de colônias por mililitro). Diferentes tipos de solventes para a CL foram testados: éter, álcool de cereais, Tween 80 e P-123. 100l do inóculo e o mesmo volume da solução teste foram inseridos em cada poço da placa de microtitulação. A mistura foi agitada e aguardou-se 1min. 25l da suspensão foi removida e diluições seriadas foram realizadas. Alíquotas de cada diluição foram espalhadas na superfície da placa, armazenadas em microaerofilia e incubadas na estufa por 24h a 37oC. O número de UFC foi contado em cada placa.

Conventional radiographic images are frequently used to detect supernumerary teeth. However, recent developments in 3D imaging systems have enabled dentists to better visualize supernumerary teeth, with better contrast and more details. Cone beam computed tomography (CBCT) has improved diagnosis and treatment planning of patients with supernumerary teeth. The decision to use CBCT should be based on the diagnostic information required. This article presents three case reports of patients with supernumerary teeth to demonstrate the need for accurate diagnosis and treatment planning based on a comprehensive evaluation using CBCT.

Mucoceles are common disorders of the minor salivary glands, occurring specially on the lower lip. Their occurrence in newborn babies has rarely been reported. In addition, the surgical removal of oral lesions in babies has often been performed with general anesthesia, which option is usually related to the patients' ages, irrespective of the lesion's size and the access to anatomic region where it is located. The present report, however, details the treatment of a mucocele excision performed in an 8-month-old baby with local anesthesia. This case illustrates well that knowledge of the lesion and dentist's experience in the attendance of babies is important, as often only conservative treatment with local anesthesia is required. Therefore, clinicians and parents should be reassured that early surgical intervention under local anesthesia will provide a swift and satisfactory resolution to the problem.
Mucocele é uma ocorrência comum nas glândulas salivares menores, que acontece, principalmente, no lábio inferior. Em bebês, tem sido raramente reportada na literatura. Em adição, a remoção cirúrgica de lesões orais em bebês tem sido realizada sob anestesia geral, cuja opção geralmente se refere à idade do paciente, sem ter relação com o tamanho da lesão e o acesso à região anatômica onde está localizada. O presente caso clínico, no entanto, descreve a excisão da mucocele realizada em um bebê de 8 meses de idade, sob anestesia local. Esse caso ilustra bem que o conhecimento da lesão e a experiência do dentista no atendimento de bebês é muito importante, já que somente um tratamento conservador sob anestesia local é necessário. Portanto, clínicos e pais devem ser alertados para o fato de que uma intervenção cirúrgica precoce sob anestesia local irá proporcionar uma resolução rápida e satisfatória do problema.
ABSTRACT
The present study aimed to compare the fluoride (F-) release pattern of a nanofilled resin-modified glass ionomer cement (GIC) (Ketac N100 - KN) with available GICs used in dental practice (resin-modified GIC - Vitremer - V; conventional GIC - Ketac Molar - KM) and a nanofilled resin composite (Filtek Supreme - RC). Discs of each material (n=6) were placed into 4 mL of deionized water in sealed polyethylene vials and shaken, for 15 days. F- release (µg F-/cm²) was measured each day using a fluoride-ion specific electrode. Cumulative F- release means were statistically analyzed by linear regression analysis. In order to analyze the differences among materials and the influence of time in the daily F- release, 2-way ANOVA test was performed (α=0.05). The linear fits between the cumulative F- release profiles of RC and KM and time were weak. KN and V presented a strong relationship between cumulative F- release and time. There were significant differences between the daily F- release overtime up to the third day only for GICs materials. The daily F- release means for RC were similar overtime. The results indicate that the F- release profile of the nanofilled resin-modified GIC is comparable to the resin-modified GIC.

Impaction of permanent teeth represents a clinical challenge with regard to diagnosis, treatment plan, and prognosis. There is a close relationship between deciduous teeth and permanent teeth germ, and any injury in the deciduous dentition may influence the permanent teeth eruption. The extent of the damage caused to the permanent teeth germ depends on the patient age at the time of injury, type of trauma, severity, and direction of the impact. Conventional radiographic images are frequently used for diagnosis; however, recent developments in three-dimensional (3D) imaging systems have enabled dentistry to visualize structural changes effectively, with better contrast and more details, close to the reality. The cone-beam computed tomography (CBCT) has been used in the diagnosis and treatment plan of these impacted teeth. The purpose of the present case report is to describe a successful conservative management of a retained permanent maxillary lateral incisor with delayed root development after a trauma through the deciduous predecessor in a 9 year-old patient. After clinical and radiographic examination, a CBCT examination of the maxilla was requested to complement the diagnosis, providing an accurate 3D position of the retained tooth and its relationship to adjacent structures. The proposed treatment plan was the surgical exposure and orthodontic traction of the retained tooth. The lateral incisor spontaneously erupted after 6 months. Therefore, this case report suggests that permanent teeth with incomplete root formation have a great potential for spontaneous eruption because no tooth malposition or mechanical obstacles are observed.

PURPOSE: This study's purpose was to assess the prevalence of dental erosion in adolescents and to investigate the association between erosion and sociodemographic characteristics. METHODS: This study consisted of a single center cluster random sample of 414 adolescents (12 and 16 years old) of both genders from private and public schools in Bauru, São Paulo, Brazil. Two previously calibrated examiners (kappa=0.85) used the O'Brien (1994) index for assessment of dental erosion on the buccal and palatal surfaces of the permanent maxillary incisors and on the occlusal surfaces of the permanent first molars. Data on gender, type of school, and mean family income were collected by a questionnaire completed by the adolescents. Descriptive statistics were applied to the data, and the associations between erosion and sociodemographic variables were investigated by chi-square test (P<0.05). RESULTS: The prevalence of dental erosion was 20% (N=83), with only enamel being involved (score 1). The labial surface was the most affected (16%). There were no significant differences between the presence of erosion and gender, type of school, and mean family income. CONCLUSIONS: The results indicate that dental erosion restricted to enamel was observed among adolescents in Bauru/Brazil, and there was no correlation between this condition and sociodemographic factors.

BACKGROUND: Dental erosion is a multifactorial disease and is associated with dietary habits in infancy and adolescence. AIM: To investigate possible associations among dental erosion and diet, medical history and lifestyle habits in Brazilian schoolchildren. DESIGN: The sample consisted of a random single centre cluster of 414 adolescents (12- and 16-years old) of both genders from private and public schools in Bauru (Brazil). The O'Brien [Children's Dental Health in the United Kingdom, 1993 (1994) HMSO, London] index was used for dental erosion assessment. Data on medical history, rate and frequency of food and drinks consumption, and lifestyle habits were collected by a self-reported questionnaire. Odds ratios with 95% confidence intervals were used to assess the univariate relationships between variables. Analysis of questionnaire items was performed by multiple logistic regression analysis. The statistical significance level was set at 5%. RESULTS: The erosion present group comprised 83 subjects and the erosion absent group 331. There were no statistically significant correlations among dental erosion and the consumption of food and drinks, medical history, or lifestyle habits. CONCLUSION: The results indicate that there was no correlation between dental erosion and the risk factors analysed among adolescents in Bauru/Brazil and further investigations are necessary to clarify the multifactorial etiology of this condition.

Discos de cada material (n=6) foram imersos em 4 mL de água deionizada em frascos de polietileno e agitados durante 15 dias. A liberação de F- (μg F-/cm²) foi medida a cada dia utilizando um eletrodo de F- específico. Os valores de liberação cumulativa de F- foram analisados estatisticamente por análise de regressão linear. Com o objetivo de analisar as diferenças entre os materiais e a influência do tempo na liberação diária de F- foi aplicado o teste ANOVA a dois critérios (α=0,05). A relação entre os padrões de liberação de cumulativo de F- da RC e KM e o tempo foram fracas. Os materiais KN e V apresentaram uma relação forte entre a liberação cumulativa de F- e o tempo. Diferenças significativas foram observadas entre a liberação diária de F- até o terceiro dia somente para os cimentos ionoméricos. Os resultados indicam que o padrão de liberação de F- do CIV modificado por resina nanoparticulado é semelhante ao CIV modificado por resina.

ABSTRACT
O objetivo deste estudo foi avaliar a prevalência da erosão dentária em adolescentes e os possíveis fatores etiológicos extrínsecos e intrínsecos envolvidos nesse processo. A amostra consistiu de 414 adolescentes com 12 e 16 anos de idade, de ambos os gêneros, matriculados em escolas públicas ou privadas da cidade de Bauru/SP. O exame clínico foi realizado por dois examinadores previamente calibrados (Kappa = 0.85), que utilizaram o índice de OBrien (1994) para avaliar as faces vestibulares e palatinas dos incisivos superiores e a oclusal dos primeiros molares permanentes. Um questionário foi aplicado para pesquisar sobre dieta, história médica e hábitos dos adolescentes. Os dados foram devidamente analisados através da estatística descritiva e dos testes do Qui-Quadrado e de Mann-Whitney. Foi adotado nível de significância de 5% para que as diferenças sejam consideradas estatisticamente significantes. A prevalência de erosão foi de 20% na amostra estudada, com envolvimento apenas de esmalte. Nenhuma superfície apresentou erosão em dentina (código 2) ou exposição pulpar (código 3). A face vestibular foi a mais acometida (16,1%) e a face oclusal a menos acometida (1,3%). Não houve diferenças estatisticamente significantes entre gênero, condição sócio-econômica e tipo de escola. Nenhum dos fatores de risco pesquisados no questionário apresentou uma associação significativa com a erosão. Os resultados deste estudo sugerem que a erosão dentária foi uma condição observada na amostra estudada e não houve correlação entre esta ocorrência e as condições e hábitos de vida desta população.
The aim of this study was to assess the prevalence of dental erosion in adolescents and determine the possible etiological factors. A sample of 414 adolescents (12- and 16-year-old) from private and public schools in Bauru participated in this study. For the dental examination, two examiners previously calibrated (kappa=0,85) made the evaluation on the labial and palatine surfaces of the maxillary permanent incisors and on the oclusal surface of the first permanent molars for the presence of dental erosion using the OBrien (1994) index. Data on dietary habits, oral hygiene practices and medical background were collected by a structured questionnaire completed by the adolescents. Descriptive statistics were applied to the data and the associations between dental erosion and the variables under study were investigated by Chi-square and Mann-Whitney analysis. The statistical significance level was set at 5%. The prevalence of dental erosion was 20% in this sample, with only enamel been involved. Erosion affecting dentine (score 2) or pulpar exposure (score 3) were not observed. The labial was the most affected surface (16,1%) and the oclusal surface the least (1,3%). There were no statistically significant differences between the presence of erosion and gender, socioeconomic status and type of school. The risk factors investigated in the questionnaire were not associated with the presence of erosion. The results of this study indicate that dental erosion was observed among adolescents in Bauru/SP and there was no correlation between this condition and the life habits of this population.
