Analysis of Food Contaminants by EDX and FTIR - Dental Materials -

Introduction

Dental materials include diverse types of restorative materials such as metals, porcelain, ceramics, and composite resins. These materials are sometimes found in food during eating, for example, in case of inadequate adhesion with the tooth or loss of adhesion due to long-term use, and are mistakenly perceived as food contaminants. In many cases, a substance which is inadvertently mixed in a food product by a consumer is presented to the manufacturer as a contaminant originating from the production process, but claims can be held to the minimum by quickly conducting an analysis to clarify the source of the contaminant. This article introduces an example of an analysis of a human tooth and various dental restorative materials that were presented to a food factory as contaminants by using EDX and FTIR.
