Abstract
Determining the esthetic success of single-tooth implant restorations (STIR) requires an objective tool such as one devised by Belser et al., 2009 - pink esthetic scores and white esthetic scores (PES/WES). This study aimed to utilized PES/WES to establish threshold scores based on (1) detectability and (2) acceptability of a STIR by lay person perception, (3) to study the difference in the ability of laypeople and dentists in detecting the presence of STIR, and (4) to study the pink and white deficiencies in relation to the detectability of the presence of STIR. A total of 38 calibrated photographs of STIR in the anterior region were scored with PES/WES by 3 prosthodontists. Next, 100 laypeople and 60 dentists were instructed to identify the STIR among the anterior teeth and provide reasoning behind the identification (based on pink and white esthetic criteria). The acceptance of the STIR was recorded. Receiver Operating Characteristics (ROC) analysis was utilized to determine the threshold scores. At the PES/WES score of 17, 71% of laypeople could not correctly identify the STIR, and at the PES/WES score of 12, 80% of laypeople accepted the implant. Out of 3,800 occasions, laypeople correctly identified the STIR 1,770 (46.58%) of those occasions. Among the correctly identified STIR, 751 (42.43%) of those occasions were identified with pink deficiencies and 1019 (57.57%) of those occasions were with white deficiencies. Out of 2,280 occasions, dentists correctly identified STIR 1869 (81.98%) of those occasions. The PES/WES score of 12 indicates the clinically acceptable threshold, while the score of 17 indicates the detectable threshold for an exceptional esthetic outcome. Laypeople tend to accept the implant despite its detectability. For both laypeople and dentists, root convexity/soft tissue color and texture are the most focused criteria of PES/WES, followed by overall white deficiencies that remain influential. Compared to laypeople, dentists tend to have a higher ability to detect STIR.
