The Long-term clinical performance of metal ceramic crowns (PFM) delivered by Undergraduate Dental Students rarely investigated. Objectives: This study reports the results of a retrospective clinical study of PFM crowns delivered by third and fourth year undergraduate students over three time periods over 15 years. Methods: 150 patients who had metal ceramic crowns delivered by Undergraduate Students between 1990 and 2005 were recalled. A comprehensive examination of the oral cavity and the metal ceramic crowns was completed. Number of criteria (a modified USPHS) for assessments were used include surface texture, color match, anatomic form of complete surface, marginal integrity, discoloration, integrity of the tooth and restorations, occlusion, post operative complaints, patient compliance, gingival response and sensitivity. The data were analyzed based on the time period in which the crowns were delivered and student experience. Three periods were chosen to compare the data: 1990-1995, 1996-2000, and 2001-2005. A 4-point scoring system (Alpha, Bravo, Charlie, Delta) was used to assess each criterion. The data were analyzed using Kruskal-Wallis and the Mann-Whitney U non-parametric statistical tests. Results: Plaque and gingival indices and anatomic form of the marginal step were rated the lowest for Alpha scores. Failure of the crowns was mainly due to marginal discrepancy and gingival response. 80.4%, 95.6% and 98.1% success rates ware observed for the crowns delivered between 1990-1995, 1996-2000 and 2001-2005 respectively. Kruskal-Wallis showed no significant statistical difference in Alpha scores between the three groups of crowns for the criteria assessed (P<0.05) except the anatomic form of the marginal step and gingival response using probing. Conclusion: The clinical performance of the metal ceramic crowns delivered between 1990 and 2005 showed steady deterioration over time. The year of the study of the students has no effect on the performance of the crowns. Marginal integrity and gingival response were major concern.
