Experimental studies on the nature of property gradients in the human dentine.

We conducted an investigation into the nature of dentine mineralization and mechanical property gradients with the aid of experimental techniques such as the fluoroscopic X-ray microanalysis and instrumented microindentation, respectively. It was found that the tooth adapts to a complex structure with significant gradients in properties. We observed a significant correlation between the degree of mineralization within the dentine and the mechanical properties.

A strain gauge and photoelastic analysis of in vivo strain and in vitro stress distribution in human dental supporting structures.

Strain gauge and photoelastic experiments have been workhorses of experimental stress analysis for over 50 years. In this study, both were used to analyse the nature of stress distribution from the tooth root surface to the supporting alveolar bone. Such studies help in understanding the behaviour of dental supporting structures under physiological function.

Biomechanics of endodontic endosseous implants--a comparative photoelastic evaluation.

Dental biomechanics is an interdisciplinary study wherein engineering principles are used for the better understanding of clinical dentistry. The present biomechanical study was done to understand the mechanism by which an endodontic implant transmits occlusal forces to the surrounding bone. In this experimental study, photoelastic techniques were utilized to compare stress distribution patterns in the supporting bone of an intact tooth, a tooth with supporting bone loss, and a tooth stabilized using an endodontic endosseous implant.
