Abstract :Dental caries is a multifactorial disease which is very much prevalent in India occurring especially in high economic group and some in middle and lower economic groups of world population. The cause is due to the acquisition of abnormal eating habits by children’s, adolescents, younger age groups. One of the conventional ways of treating dental caries is by excavation by using slow and high speed hand pieces. This has become very much true in developing countries like India. The most common instruments used for excavation of dental caries are the use of diamond and carbide burs. There is effective removal of the carious tooth structure through these burs which leads to excess removal of tooth structure and weakening the teeth. Since minimally invasive dentistry came into the practice, many innovative materials have been introduced i.e. Polymide polymer burs are one of the ways used for excavation of dental caries which helps in removing only the carious part of the tooth and wears of once it reaches and starts cutting sound tooth structure. This article aims to review its applications and discuss its effectiveness based on evidence available through latest published studies.
