Application in nanomedicine of manganese-Zinc ferrite nanoparticles
No full textBesides the study and the medical application of iron oxide nanoparticles, ferrites produced with zinc and manganese are of particular interest for their properties. The introduction of these elements into the crystalline structure of the magnetic particle generates some changes in the material properties, enhancing their potential use in theranostic applications. This review will cover the most important aspects of the preparation of these materials, taking into account the different methods of synthesis, and will analyze the most promising results in their use in MRI, magnetic hyperthermia and other emerging applications

No full textEffect of water contamination on the shear bond strength of self-ligating brackets
No full textPurpose: The aim of the present study is to evaluate the effect of water contamination on the shear bond strength (SBS) and adhesive remnant index (ARI) score of self-ligating brackets.
Materials and methods: One conventional bracket and three different self-ligating brackets were bonded onto 160 bovine permanent mandibular incisors, divided randomly into 8 groups. For each type of bracket, 20 samples were bonded on dry enamel and 20 after water contamination. After 24 h, all specimens were tested for SBS using an Instron Universal Testing Machine, and ARI scores were evaluated.
Results: All groups showed clinically adequate SBSs. Quick brackets bonded onto dry enamel showed significantly higher SBSs than all other groups tested, whereas the lowest shear strength values were recorded for Step, Quick, and Damon 3MX brackets bonded onto contaminated enamel and for Damon
3MX onto dry enamel. Frequency distribution of ARI Scores showed a prevalence of ARI “2” and “3” for all the groups tested.
Conclusions: Water contamination reduces the SBS of self-ligating brackets, but significant differences have been found only for Quick brackets. All groups showed a significant higher frequency of ARI Score of “2” and “3”
