Survival of Root Canal Treated Teeth Restored With Ceramic Onlays
The Success and Survival of Teeth and Restoration Following Root Canal Treatment With Varying Degrees of Tooth Structure Loss Restored With CAD CAM Restorations.
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.

説明
Inclusion Criteria:
- Patients either male or female over the age of 18 (who can consent for themselves) in good general health.
- The selected teeth needed to be in occlusal function with a natural tooth and in interproximal contact with two adjacent natural teeth.
- Molar or premolar teeth with suspected endodontic problems that require root canal treatment.
- Teeth should not be mobile and must be restorable.
Exclusion Criteria:
- Pregnant women, in view of requirements for radiographs (or if they could possibly be pregnant). To be confirmed by the Medical History Questionnaire.
- Patients younger than 18.
- Patients unable to give consent.
- Teeth with probing periodontal depths greater than 5 mm.
- Non-restorable teeth.
- Not involving patients from prisons.
- Not involving patients who cannot read, write or understand English
