Introduction- Zirconia is a high-strength ceramic material with highfracture toughness, almost similar to that of porcelein fused to metal (PFM) crowns. The present study was conducted to assess the comparison of PFM crown with zirconia crowns. Materials & Methods: The present retrospective study was conducted on 440 patients of both genders. Patients were divided into 2 groups depending upon type of crowns. Group I consisted of 220 patients who received PFM crowns and group II consisted of 220 patients who received Zirconia crowns. All patients were assessed for loss of retention, fracture, root separation, sensitivity, secondary caries and endodontic problem. Results- Out of 440 patients, group I had 220 patients (males- 100, females- 120) and group II had 220 patients (males- 140, females- 80). The difference was non- significant (P- 1).Loss of retention was seen in group I (12) and group II (10), fracture in group I (25) and group II (20), root separation in group I (10) and group II (12), sensitivity in group I (5) and group II (4), secondary caries in group I (17) and group II (18) and endodontic problem in group I (14) and group II (12). The difference was non- significant (P> 0.05). Conclusion- Both PFM and zirconia crowns found to be equally effective in terms of retention, sensitivity, secondary caries, root fracture. However, zirconia showed slight better results.
Key words-Senstivity, Endodontic,  Zirconia.
