Measurement technique for the healty and carious teeth based on thermal analysis

In the mineral part of the teeth the calcium phosphates and calcium carbonates are combined in a collagen with the mucopolysaccharides of the organic matrix. The infection on the tooth surface caused by bacteria can modify the tooth structures resulting in the tooth decay. In order to determine the modification on the tooth structure the use of thermal analysis technique is proposed. With this aim is fundamental the definition of an experimental protocol for the preparation of the sample under examination that does not modify the structure of the tooth. Preliminary experimental results confirm the capability of the measurement technique pointed out to correctly classify the modification of the tooth structure due to the aging or the carious.
