Mathematical prediction of dental removal rate in drill-less dentistry

Abstract

Dental problems such as tooth ache and other related disorders are very common among people irrespective of countries. The contemporary food consuming culture aggravated dental issues especially among children who all are suffering a lot. Dental science is a part of medical science has introduced several advancements as remedies in tackling these problems. Nevertheless, the focus is still on researches to explore the effective solutions in the removal of tooth caries. Conventional techniques prefer the tooth removal as preventive measure to end the dissemination of tooth caries. Drilling is an example for conventional practice in caries removal followed by filling with amalgam and other means of filling. This tooth elimination and subsequent processes leads to heat generation, vibrations and noise inducement in the processing tooth. Consequently, patient suffers from pain. Drill-less dentistry is a novel technique that can handle the caries removal without any painful moments. The present work is concerned with drill-less dentistry and come up with a solution in the form of mathematical expression for caries removal rate. The derivation of respective expression revealed that mass flow rate, impact velocity and density of particles (abrasives) are the most influencing factors in deciding the caries removal rate.
