Resumo Quais as repercussões da urbanização mal planejada na saúde da população? Entender a saúde urbana, os riscos acarretados pelas cidades, as repercussões na saúde e as relações sociais auxiliam no planejamento no qual a prevenção deve ser investida. Assim, com o objetivo de verificar a relação entre urbanização e saúde urbana, em especial as infecções ocasionadas pelo vetor “Aedes aegypti”, foi realizado um estudo qualitativo e uma investigação descritiva e analítica através de busca documental e bibliográfica. Os resultados apontam que os impactos ambientais decorrentes da falta de infraestrutura resultante da urbanização podem oferecer riscos à saúde humana, visto que a disposição de resíduos em lixões e aterros podem ocasionar exposição a substâncias químicas perigosas à saúde. Além disso, o saneamento ineficaz pode acarretar em doenças veiculadas pela água e propiciar a reprodução de vetores de outras enfermidades, como é o caso do “Aedes aegypti”, responsável pela transmissão das arboviroses (dengue, chikungunya e Zika). Dessa forma, estudar saúde ambiental e urbana proporciona embasamento para a promoção de qualidade de vida das pessoas que residem nessas áreas e permite propor medidas que evitem doenças relacionadas à urbanização.

To describe the oral findings observed in a case series of children with Congenital Zika Syndrome (CZS). The patients attending in a Basic Unit of Health from a municipality in northeast Brazil were evaluated by means of anamnesis and clinical oral examination. All procedures were carried out by a single researcher. The final sample consisted of 12 subjects (six males and six females), with ages ranging from 36-40 months old. It was observed higher percentage of children that tooth brushing twice a day and with nocturnal bottle feeding habit. The most prevalent oral findings were presence of visible biofilm, bruxism and delayed tooth eruption. The results suggest that some oral alterations might be part of the phenotypic spectrum of CZS. This study can potentially help dentists to understand the importance to establishment early diagnosis and intervention of oral conditions, with a multidisciplinary approach focused on health promotion and individual well-being.

As ações de promoção de saúde bucal, particularmente as direcionadas ao público infantil, devem ser acionadas por meio de ferramentas que tornem o processo de aprendizagem mais dinâmico e de fácil compreensão. Assim, este trabalho visa relatar a importância da utilização do lúdico como estratégia para promoção da saúde bucal infantil. A escolha de um recurso ou da associação de diferentes estratégias lúdicas, como jogos educativos, teatro, música e exposição de macromodelos, deve ser feita de forma racional e considerando não apenas as preferências e habilidades do profissional, mas, sobretudo, a adequação dos temas, regras e ações da atividade à idade e ao nível cognitivo e motor de desenvolvimento da criança. O importante é as informações serem reforçadas e transmitidas de forma simples e envolvente para que os participantes tenham o raciocínio e a criatividade estimulados e a oportunidade de interagir de modo harmoniosa, inclusivo e feliz.

Mesiodens is the most frequent type of supernumerary tooth and may occur in several forms, causing different local disorders, such as impaction of the anterior permanent teeth. High-resolution three-dimensional (3D) images have improved the diagnosis and treatment plan of patients with impacted and supernumerary teeth. The purpose of this paper was to report a case of two mesiodens in monozygotic twin boys with appropriate 3D diagnostic and treatment plan.

CBCT is an important auxiliary tool, aiding in both correct diagnosis and accurate treatment planning. It is currently a technology accessible to most paediatric dentists and should be beneficial considering the diagnostic information provided as well as the cost-benefit ratio for the patient.

Mucocele is a benign lesion, originating from disorders of minor salivary glands containing mucus. These lesions are found in children and young adults and usually occur due to local trauma. Clinically, it presents as a circumscribed, asymptomatic, soft and bluish or normocromic blister. The treatment of choice is surgical removal, when the lesion does not rupture naturally. This study aims to report a clinical case of mucocele in a pediatric patient removed through total surgical excision. A 7-year-old patient accompanied by mother sought care at the Dentistry Clinic of the “Tiradentes” University Center (UNIT / AL), with a main complaint of asymptomatic blister in the lower lip for about 15 days. In the anamnesis, the habit of biting in the region was reported. At clinical examination, a blister with clear limits of approximately 10 mm in diameter was observed in the lower lip mucosa, with slightly firm/fibrous consistency, which gave rise to doubts about the possible diagnosis, since it presented characteristics similar to that of a mucocele, although consistency at palpation indicates possible fibroma. Surgical excision of the lesion was performed; the material collected was fixed in 10% formalin and sent to histopathological examination that confirmed the diagnosis of mucocele. The patient was kept on follow-up, and there was no recurrence of the lesion. Surgical excision demonstrated an effective and prognostic therapeutic course, allowing accurate diagnosis through the histopathological evaluation of the lesion.

Introduction Proper storage conditions and maintenance of viable biological material plays an important role in microbiological research, allowing for the opportunity to conduct future studies. Objective To evaluate the viability of Streptococcus mutans strains that were previously grown and stored under different temperatures for approximately eight years. Material and method In this study, we evaluated 393 bacterial isolates that were stored in a freezer at -80°C (G1) and 200 isolates stored in a freezer at -20°C (G2). Aliquots of each sample were plated on blood agar and mitis-salivarius bacitracin sucrose agar-solidified medium. After incubating under microaerophilic conditions in an incubator at 37°C for 72 hours, the presence, morphology and purity of bacterial growth was observed. The data were analyzed by means of descriptive statistics. Result Microbial viability was observed in almost all samples (99.7%) in G1, whereas all isolates stored at -20°C were considered inviable. Conclusion The viability of S. mutans is influenced by the storage temperature of the samples, and the strains remain viable when stored under ideal temperature conditions (-80°C), even when stored for a long period of time.
