Retrospective study on the performance of porcelain laminate veneers delivered by undergraduate dental students

The aim of this study was to retrospectively evaluate the clinical performance of porcelain laminate veneer restorations delivered by undergraduate students at the Department of Restorative Dentistry, University Dental School and Hospital Cork and to analyze the factors that influence their prognosis and their effect on periodontal health. Patients who had veneers fitted over a period of 5 yrs. were recalled for evaluation. The recall protocol took the form of a questionnaire and a full clinical examination of the teeth involved and contra lateral control teeth. In all, 29 patients with 62 porcelain veneers were examined, only 2 of which were in the mandible. 77% of patients had veneers fitted due to discolouration, 13% in order to alter the shape or size of teeth and 10% due to palatal erosion. On the date of recall 89% of veneers had never debonded or fractured, 6% had to be rebonded since the date of insertion and 5% presented with a fracture. From this study it appears that porcelain laminate veneers are successful in the treatment of discoloured and irregular configured anterior teeth. It shows that undergraduate students can deliver satisfactory veneer restorations.
