Abstract

Various methods have been used to study the root canal morphology of human teeth. The purpose of this study was to develop a technique for the formation of a resin replica of the root canal morphology of maxillary first premolars. 30 recently extracted maxillary first premolars were used for the study. An occlusal access cavity was prepared and the teeth placed in 5% sodium hypochlorite solution to dissolve the pulp remnants. The teeth were then rinsed in water. A two-part resin system was then introduced into the root canal through the access cavity opening. Subsequent to curing the resin using a specific curing cycle the specimens were put in 20% hydrochloric acid. This facilitated the dissolution of the tooth and the retrieval of the resin replica of the root canal. The different types of root canal morphology observed are discussed. The relevance and utility of the resin models and further possibilities in this field are discussed.
