It is well known that there will be increase in the temperature of the tooth's surface during certain dental procedures and has greater interest is their potential damaging effect on the pulp of the tooth. Many studies have investigated the responses of the dental pulp to thermal irritation and the temperature at which thermal damage is initiated. There are also many in-vitrostudies that have measured the temperature increase of the pulp and tooth-supporting tissues during restorative procedures. This review article provides an overview of studies measuring temperature increases in tooth structures during tooth preparation, and proposes clinical guidelines for reducing potential thermal hazards to the pulp and supporting tissues by various methods and armamentariums used to control heat production
