Mathematical prediction of dental removal rate in drill-less dentistry

People all over the world are suffering from tooth ache and other tooth disorders. These problems are very harmful to today’s young children’s due to the contemporary food habits. There are so many advancements in the field of medical science. Still there is a requirement of convenient method for removing the tooth caries from the tooth. The techniques that are conventionally practiced such as removal of the entire tooth for the prevention of further distribution of tooth caries, or drilling out the part of the tooth caries and filling it with amalgam or other tooth pastes will result in lot of heat, noise and vibration in the tooth structure which results in ultimate pains to the patients after the removal of the tooth caries from the tooth even though there is no pain during removal because of anesthesia. In order to avoid these problems, a new technique emerged called as Drill-less dentistrywith the aid ofmicro air abrasion technique. The present work deals with mathematical modelling of dental removal rate in Drill-less dentistry. These mathematical expressions reveal that the enamel and dentin removal rate depends upon the value of mass flow rate of abrasives, velocity of abrasives and density of the abrasives.
