Non-destructive Microstructural Evaluation of Intact and Restored Human Teeth Using Tabletop X-Ray $$\upmu $$ μ CT System
Source abstract
Abstract
This study explores the feasibility of a micro-focus based tabletop X-ray $$\upmu $$ CT system for the micro-structural characterization of human teeth and later its application to the non-destructive evaluation of teeth restored with different composite resin for their interface integrity and micro-imperfections. In the first part of this study, extracted human primary and permanent molar teeth were used to explore potential of micro-focus based tomography setup for their micro-structural characterization. The details of root canal structure of human teeth were visualized and quantified with polychromatic $$\upmu $$ CT. In the second part identification and comparison of defects in a set of six human teeth samples, which were restored with two different composite resins, was carried out. Group ‘A’ samples were restored using a submicron hybrid composite material and Group ‘B’ were restored with a Nano-hybrid restorative composite material. The quantitative analysis of $$\upmu $$ CT data for composite resin restored teeth showed more number of voids or defects in Group ‘A’ restorations compared to Group ‘B’. A comparative evaluation of $$\upmu $$ CT techniques based on synchrotron source and micro-focus source is also illustrated to show their respective merits and limitations.
