RESUMO
Molar incisor hypomineralization (MIH) is a qualitative developmental defect of enamel that occurs during the mineralization phase. Patients with MIH have increased risk of caries, hypersensitivity, and restoration failures. The present case report describes the treatment of a 10-year-old patient exhibiting two teeth with atypical carious lesions. A minimal interventive protocol was instituted combining antimicrobial photodynamic therapy and the selective chemical-mechanical removal of the carious tissue using the product Papacárie Duo®. This protocol is promising for the decontamination and control of hypersensitivity in teeth with MIH.

Some plants popularly employed for the treatment of peptic ulcers have proved to be attractive sources of new drugs. Despite extensive research, the pharmacological and toxicological potentials of these plants are not fully understood. In this context, the aim of this work was to analyze the multielemental composition of the methanolic extracts of three of those plants, Alchornea glandulosa (AG), Davilla elliptica (DE) and Davilla nitida (DN), with the intention of contributing to the understanding of the mechanisms of action of these extracts. For this purpose, we used the analytical technique of total reflection X-ray fluorescence (TXRF) by synchrotron radiation at the Brazilian Synchrotron Light Source (LNLS/CNPEM). It was possible to determine the concentrations of the elements: P, S, Cl, K, Ca, Ti, Cr, Mn, Fe, Ni, Cu, Zn, Rb and Br in all of the samples. Selenium (Se) was detected only in the DN extract. An inverse relationship between the concentrations of elements with proven effectiveness and the gastroprotective activity of extracts considering induction protocols with ethanol and non-steroidal anti-inflammatory drugs (NSAIDs) was obtained. This data suggests that the function of the extract is not only associated with providing the elements for restoring the gastric mucosa but that it also promotes the displacement of these elements from other parts of the mucosa to the damaged area. Correlations between the concentrations of the elements were also obtained. In the DE extract, which is the most effective extract for both induction protocols, the obtained correlations were above 70% among almost all of the elements, and no anticorrelations were found. For the other two extracts, in the less effective extract (AG) anticorrelations above 70% were predominantly found. Meanwhile, in the DN extract, a few high anticorrelations were found, which may explain its intermediate stage of effectiveness.
RESUMO
O TRA (Tratamento Restaurador Atraumático) surge como aliado à odontologia de mínima intervenção,dispensando os avanços tecnológicos, o enfoque estritamente invasivo e curativo, muitas vezes disponíveis auma pequena parcela da população e não atendendo às camadas sociais menos favorecidas dos países emdesenvolvimento e subdesenvolvidos. O TRA dispensa infraestrutura, técnica e custo monetário complexos,utilizando ações eficazes que visam à multiplicação da saúde bucal. A técnica inclui mínima intervenção emáxima preservação de estruturas dentárias, bem como, o uso de materiais odontológicos biologicamentecompatíveis e agregadores à saúde bucal do paciente. Este artigo tem como finalidade expor em revisãobibliográfica a cerca da utilização do TRA e sua aplicabilidade em comunidades menos assistidas, bem comosuas características e eficácia técnica
The Atraumatic Restorative Treatment (ART) arises as an ally to the minimally invasive Dentistry giving up thetechnology, the approach strictly invasive and healing many times available for a minority, not reaching the lessfavored areas from developed and developing counties. The ART doesn't need infrastructure technique or highcost using effective measures aimed on increase the oral health. The technique includes less intervention andmaximum dental structure preservation, also the correct use of dental materials bringing dental health for thepatient. This article has the goal to expose as a literature review the ART and your applicability in less favoredareas, your efficiency and technical features
