Artigo Científico Acesso fechado Análise da adaptação marginal e porosidade do MTA flow na presença de sangue(2019) Westphal, LuanaIntroduction: Teeth with incomplete rhizogenesis and necrotic pulp have their development interrupted leaving a wide canal, thin dentin walls and open apex. In these cases, the apexification is the best treatment option, as it allows better conditions for the filling. The MTA flow came with the characteristic of having grater plasticity and this facilitate the use in apexification and apical plugs. The aim of this study was to analyze the influence of the marginal adaptation and porosity of the MTA Flow in contact with blood, by computerized microtomography. Materials and methods: Twenty-four bovine incisors roots with 10 mm height were filled in the apical third with MTA Flow. The specimens were randomly divided into two groups according to storage - blood (G1) and saline (G2)- and remained in a controlled environment for 7 days. All specimens were submitted to analysis by computerized microtomography, evaluating the parameters marginal adaptation, number of pores and percentage of porosity. The results were evaluated by Student’s t-test. Results: there was no significant difference between groups in all evaluated parameters. Conclusion: It can be concluded that blood has no effect on MTA Flow marginal adaptation and porosity.
