Our results suggest that pitted enamel in patients with mucopolysaccharidosis is most likely a feature of mucopolysaccharidosis type IVA; whereas, open bite is rarely observed in these patients. Orofacial features in mucopolysaccharidosis may help pediatric dentists recognize this disorder and minimize the delay between the initial signs/symptoms and diagnosis of the disease. Future studies should focus on the longitudinal manifestations, expression, and severity of mucopolysaccharidosis-associated orofacial anomalies.

Background:The highest prevalence of protein-energy undernutrition is observed during early childhood, being also a time in which the presence of dental caries can be unusually aggressive. The present study aimed to verify if different levels of undernutrition could influence the risk of early childhood caries (ECC), in the presence of other predisposing factors. Methods: One hundred and twenty undernourished 12-70 month old children, with or without ECC, were selected. Undernourished children were classified as being mildly, moderately or severely undernourished. All children were examined for determination of decayed, missing and filled surfaces (dmfs). Total protein concentration in saliva was analysed by the Bradford method. For microbiological analysis, mitis salivarius-bacitracin agar medium was used. A binary logistic regression model was applied to test the simultaneous influence of different variables over caries experience. Results: The risk of ECC was significantly higher with an increase in age (p = 0.000) and mutans streptococci counts (p = 0.032). Comparisons with the normal-weight group showed that mildly (p = 0.004) and severely undernourished children (p = 0.037) had a higher risk of experiencing ECC, but this risk was not significantly elevated among moderately undernourished children (p = 0.158). Conclusions: Our results suggest that mildly and severely undernourished children have an increased risk of experiencing dental caries. Age is highly associated with the disease in this population.

The protein profile in saliva varies according to the presence or absence of PEU, and these variations are specifically expressed in different grades of undernutrition. Thus, saliva may be an important diagnostic tool for the assessment of PEU.

Objetivo: Investigar a relação entre maloclusões e desordens de ordem respiratória: rinite alérgica, hipertrofia de adenoide e de tonsilas palatinas em crianças.Material e Métodos: Realizou-se levantamento bibliográfico sobre o tema na base de dados PubMed, de 2007 a 2017, buscando artigos em inglês e português com as palavras-chave: maloclusão, odontopediatria, respiração bucal, adenoide, mordida cruzada, rinite alérgica, amídalas, em português e inglês. Foram incluídas as bibliografias que contivessem os descritores e, de exclusão, os que não atendessem à temática ou que não estivessem disponíveis na versão completa. Foi feita uma revisão da literatura, desenvolvida seguindo os preceitos de um estudo explanatório, por meio de pesquisa bibliográfica dividida em etapas. Muitos estudos mostraram que existe relação entre as desordens do trato respiratório superior (rinite alérgica, hipertrofia de adenoide e de amídalas) e alguns tipos de maloclusão.Conclusão: Ancorado nos achados bibliográficos, existe uma relação das desordens do trato respiratório e as maloclusões, por isso um acompanhamento multiprofissional é imprescindível, apontando relação direta entre prognóstico e precocidade no início do tratamento.
