Condition(s) studied

Endodontically Treated Teeth

Investigational drug(s) / intervention(s)

resin nanoceramic blockzirconia-reinforced lithium silicate

resin nanoceramic block: Resin-based CAD/CAM materials

zirconia-reinforced lithium silicate: zirconia reinforced lithium silicate ceramic

Study summary

The clinical performance of two different materials in endodontically treated teeth produced with CAD/CAM system will be evaluated and compared. After obtaining a signed informed consert form from all the patients, all restorations will be placed by a single clinician. All endocrown restorations will be produced using the same CAD/CAM system. 52 restorations will be fabricated using Lava Ultimate (LU, 3M Espe, Seefeld, Germany) blocks and 38 restorations will be fabricated using Celtra Duo (CD, Dentsply Sirona, York, PA, USA) blocks. All restorative procedures will be conducted according to manufacturers' instructions. Restorations will be scored using modified United States Public Health Service (USPHS) criteria after baseline, 6,12,36, 48, 60 months. Descriptive statistics will be performed using Chi-square and Fisher exact test.
