简要总结
Advances in digital dentistry coupled with increased demand for aesthetic restorations have led to developments in CAD CAM( Computer Aided Design and Computer Aided manufacturing)systems for manufacturing tooth restorations. CAD CAM restorations have the added benefit of digital impressions which eliminate the need to take conventional impressions, something patients find difficult to tolerate. CAD CAM restorations are now part of routine dental care. However there are no clinical studies evaluating these restorations on root canal treated teeth
This study aims to compare the success and survival of root canal treated teeth and/or restoration with varying degrees of tooth structure loss restored using CAD CAM restorations.
Null Hypothesis:- The amount of residual coronal dentin has no effect on the survival of root canal treated teeth and/or restoration.
详细描述
This study will be carried out at KCL Dental Institute at Guy's Hospital and will form part of the routine dental treatment done at the endodontic postgraduate unit. Potential volunteers will be given written information about the process and be given time to consider participation. Once any questions have been answered, fully informed written consent will be obtained if they are interested in taking part. Patients requiring endodontic treatment with varying degrees of tooth structure loss will be detected, diagnosed and treated by endodontic MClinDent postgraduate students at Guy's hospital using suitable clinical techniques. The teeth will then be restored using CAD CAM restorations. Dental periapical radiograph and cone beam computed tomography (CBCT)scans (Morita Accuitomo) will be taken at baseline, 12 months and 24 months. Clinical assessment and radiographical evaluation will be carried out immediately after endodontic treatments have been accomplished and 1 and 2 years post treatment and will be assessed independently by a group of examiners. It is hoped that data analysed from this study will provide a definitive clinical evidence base for the success and survival of endodontically teeth and/or restorations.
