A Characterization of the Mechanical Behavior of Resin-Infiltrated Dentin Using Nanoscopic Dynamic Mechanical Analysis

摘要

This study explored the spatial variations in mechanical behavior of resin-infiltrated dentin using nanoscopic Dynamic Mechanical Analysis (DMA).ObjectiveThe objectives were to: 1) evaluate the mechanical behavior of resin-infiltrated dentin using a scanning-based approach to nanoindentation, 2) identify contributions of the collagen matrix to time-dependent deformation of the hybrid layer, and 3) assess the importance of specimen hydration on the nanoDMA response.
