Simulated canals in clear resin blocks have been widely used in pre-clinical endodontic teaching. The artificial canal provides direct visualisation of procedures in root canal treatment. Stanuardised simulated root canals have been produced in the Faculty of Dentistry, University of Malaya for dental education and research. The canals are easy and inexpensive to construct. An outline of the method of construction of resin simulated canals is presented in this paper.
