Journal Title: RSBO - Year 2010, Vol 7, Issue 4
Abstract
Objective: The aim of this study was to evaluate the knowledge on crown-root fractures among professors and students of a school of dentistry. Material and methods: A questionnaire comprising the treatment options for crown-root fractures at different depths and their follow-up periods was applied to 122 subjects divided into three groups: 1) students who had not attended any Endodontics and Surgery disciplines, 2) students who had concluded these disciplines; and 3) professors. The data was analyzed by descriptive statistics. Results: Most of Group 1 (90.3%) did not know the procedures to be adopted in cases of crown-root fractures. Conversely, more than 80% of Group 2 and 95% of Group 3 knew the procedures. Concerning to crown-root fractures up to 2mm deep, 26.9% of Group 1 and 48.5% of Group 3 would perform crown lengthening; 46.2% of Group 2 would perform fragment rebonding. In relation to fractures between 2 and 4mm deep, 21.2% of Group 1 would perform tooth extraction; 28.6% of Group 2, fragment rebonding; and 40.7% of Group 3, orthodontic extrusion. In fractures more than 4mm deep, most members of all groups would perform tooth extraction followed by implant. With regard to follow-up appointments, most members of all groups stated that their frequency should be at every 6 months (during the first year) and every year (for 5 years). Conclusion: Students of Group 1 showed poor knowledge on crown-root fractures, while members of Groups 2 and 3 showed a proper knowledge.
