Abstract

Aim: To gather data from Diplomates of the American Board of Endodontics regarding treatment of dilacerated canals. Materials and methods: A questionnaire addressing definition, endodontic treatment procedures and prognosis was constructed and distributed via e-mail to 708 Diplomates of the American Board of Endodontics. Data from 150 respondents, a 21 response rate, were collected by using a Web-based interface. For statistical analysis, Chi-square tests were used. Results: More than 25 of respondents believed that a dilacerated root should have a curvature > 40°. One-visit treatment is the best therapeutic approach and transportation is the most likely complication in preparation of these canals. A crown-down technique, watch-winding motion and a master apical file # 25 are the best choices for preparation of these canals. Any warm obturation technique is preferred over lateral compaction by most respondents. Conclusion: A crown-down technique for root canal preparation and a thermoplastic obturation technique are recommended for canals whose curvature is more than 40°. The prognosis of the treatment of these canals is judged not lower than normal canals. Clinical significance: Crown-down technique and thermoplastic obturation are recommended for dilacerated canals.
