Objective:
To analysis the relationship between esthetic characters and satisfaction degree of patients.
Methods:
Ninety patients requiring single anterior tooth restoration were treated in clinic with all-ceramic crowns. A visual analogue scale (VAS) was used to assess the satisfaction degree of patients after treatment. Clinical assessments were made by a prosthodontist in characters of feature, surface texture, hue, color distribution, incisal transparency, and individual characterization of all-ceramic crowns. Color-difference between the crowns and corresponding natural teeth was tested by Vita Easyshade electrical colorimetric instrument. The relationship between the last two items and patients' satisfaction degree was analyzed.
Results:
There were significance differences in the different degree among all the six esthetic characters (P < 0.05), except good and moderate degrees in the character of hue (P = 0.553). And color distribution, individual characterization, and surface texture of the crowns showed high correlations with the satisfaction degree of patients (r = 0.485, 0.472, 0.467). Total color-differences, absolute value of hue-differences, and Deltaa between restorations and corresponding natural teeth were related to the satisfaction degree of patients, and Spearman correlation coefficient was -0.434, -0.371, and -0.406 (P < 0.05), respectively.
Conclusions:
All the esthetic characters assessed in clinic were related to the satisfaction degrees of patients, especially color distribution, individual characterization and surface texture. Total color-differences and hue-differences were correlated with the satisfaction degrees of patients as well.
