Introduction: To evaluate two patients with implant-supported single-tooth restorations in the maxillary anterior region using the pink esthetic score/white esthetic score (PES/WES) and Copenhagen index score (CIS).
Methods: A questionnaire study was conducted at the Lokman Hekim University Faculty of Dentistry to evaluate two different photographs of patients with a single implant restoration in the anterior region and a natural tooth symmetrical to this restoration. Forty-five 4th and 5th year students participated in the evaluation. The questionnaire asked for the scores of PES/WES and CIS. The scores for PES/WES were 0 for significantly different, 1 for slightly different, and 2 for no difference; for CIS, the scores were 1 for excellent, 2 for satisfactory, 3 for moderate, and 4 for poor similarity. The student scores for each esthetic index were calculated as percentages (%). The study was conducted in accordance with the Declaration of Helsinki.
Results: The PES/WES score 0 values for Case 1 was as follows: mesial papilla 21.1%, distal papilla 26.3%, crown form 18.4%, and crown surface structure 18.4%; whereas for Case 2, mesial papilla was 11.1%, distal papilla 15.6%, crown form 26.7%, and crown surface structure 11.1%. The CIS score 4 values for Case 1 was as follows: crown morphology 0%, symmetry/harmony 2.6%, mesial papilla 5.3%, and distal papilla 5.3%; whereas for Case 2, crown morphology was 9.3%, symmetry/harmony 7%, mesial papilla 4.7%, and distal papilla 4.7%.
Discussion and Conclusion: The CIS provided more options, and the percentage distribution of the results was closer to each other. The CIS was found to be more applicable in the esthetic evaluation of restorations.
