Endodontic Treatment of Mandibular (First,Second) Premolars with Severely Curved Root Canal: A Report of 2 Cases
Abstract
Before endodontic treatment, it is important to consider root canal morphology. The morphologic variations in root canal such as long, narrow; and curved canals are prone to endodontic mishaps. Endodontic treatment consists of different stages including access cavity preparation, instrumentation, irrigation, and obturation of the root canal system, which can all be influenced by root canal curvature. This cases’ report presents step by step in treating mandibular first and second premolars with degree of root canal curvature 75° and 55° which was measured by using the method described by Schneider. The first case can’t be contacted after restoration with post and crown. After one year follow-up of the second case, it was found that the treatment outcome was favorable without clinical symptoms; rarefied lesion on periapical area decreased in size, as revealed by radiographic examination.
