RESTORATION OF ROOT CANAL TREATED TEETH WITH DIRECT COMPOSITE ONLAYS: A PROSPECTIVE CLINICAL STUDY
The aim of this study was to clinically assess the success rate of direct composite onlays used to restore badly damaged endodonticaly treated teeth, and if it can be an alternative for the conventional crown. This study was carried out in conservative dentistry clinic, King Hussien Medical Center. Seventy five patients (36 males and 39 females) were selected with severely destroyed posterior teeth (34 molars and 41 premolars).
These teeth were restored with direct composite onlays. A follow up after a two year interval was performed to assess the survival rate. Out of 75 patients treated with direct composite onlays 65 were available for follow up after 2 years. Sixty tow patients revealed complete success and 3 patients revealed a fracture of the onlay.
The success rate after two years follow up interval was around 95.38%. Direct composite onlays have a high success rate (at 2 years) and it represents a feasible ,successful and more conservative choice for restoration of endodontically treated teeth.
