Abstract
[...]a study was planned to evaluate the association of coronal restorations and survivability of endodontically treated teeth in the Department of restorative and dental sciences, King Khalid University, Abha. 2. Post-endodontic treatment restorations have been highlighted as important in previous studies, wherein it has been shown that, when teeth had been subjected to a quality endodontic treatment followed by adequate coronal restoration, 91.4% of the cases evidenced healed periapical lesions. [...]it has been observed that, even if the endodontic treatment was poor, yet followed by a good coronal coverage with permanent restoration, it would result in an approximate success rate of 68%. The results of the present study show that, out of a total of 121 endodontically treated teeth, 46 were crowned, 39 amalgam-restored, 25 compositerestored, 6 glass ionomer (GIC)-restored. [...]it is found out that the cases with successful endodontic healing included: 30 (65.21%) crowned teeth, 19 (48.71%) amalgam- restored teeth, 9 (36%) composite-restored teeth and 1 (16.6%) GICrestored tooth. [...]a good coronal restoration could help a long-term survival of the endodontically treated tooth (if providing optimal coronal seal), protect cusp fractures and prevent further primary infection [21].
