The aim of this study was to show a novel and accurate digital measurement protocol by analyzing the area volume for interproximal tooth enamel surface reduction. In total, 14 lower teeth from all dental sectors were embedded into an epoxy resin distributed as arch, keeping contact points. experimental model submitted intraoral impression before after reduction using air-rotor strips then re-co...

Various methods have been applied to evaluate the effect of erosion and abrasion. So, the aim of this study was to check the applicability of stylus profilometry (SP), surface hardness (SH) and focus-variation 3D microscopy (FVM) to the analysis of human enamel and dentin subjected to erosion/abrasion. The samples were randomly allocated into four groups (n = 10): G1-enamel/erosion, G2-enamel/e...

statement of the problem: enamel and dentin marginal sealing ability of the new adhesive materials could play an important role in successful restoration on fluorosed teeth. purpose: the aim of this in vitro study was to evaluate the marginal microleakage of low-shrinkage silorane-based composite, nano-ionomer, and methacrylate-based composite through self-etching approach or with enamel acid e...

Gallbladder percutaneous tissue sampling is a not-so-common technique in cytohistological diagnosis of gallbladder or masses, which can be useful cases surgically unresectable disease and unfeasible endoscopic assessment to address the most adequate chemotherapy course. Nonetheless, great utility patient’s diagnostic therapeutic work-up. This article summarizes literature evidence on biopsy tec...
