Tooth field stress calculation by finite element method during traditional and ultrasonic teeth root canal treatment

The human body represents the most important topic for many researchers. In our days, the science complexity demands the involvement of many resources and the coordinated team work of doctors, engineers, and other specialists. In the case of dental medicine, due to the nature of teeth material, their dimension and geometrical position, very important problems, like fractures, cannot be studied with classical engineering tools, such as tensometric markers. In these conditions, the finite element method is the only method that can show what is happening inside the tooth. This paper presents a model and the simulation results of the tooth response in the case of ultrasonic and traditional root canal treatment in different working conditions. In the work, stressfieldis calculated for different forces acting on the root canal. The results are important to dental practitioners for their everyday work because they request this study.
