Influence of Esthetic Dental and Facial Measurements on the Caucasian Patients' Satisfaction

Abstract

The purpose of the present study was to investigate how some esthetic dental and facial measurements may correlate the variability of patients' ratings of their satisfaction with the maxillary anterior teeth appearance in different gender groups. The following measurements were made on 78 Caucasian subjects: width and length of each maxillary anterior tooth, their distal gingival zenith displacements, the upper lip height, intercommisural width, maximum maxillary central incisal, and gingival display at rest and smile. All the patients rated their satisfaction with the dental appearance on the visual-analogue scale (0 meaning absolute dissatisfaction, whereas 4 indicated complete satisfaction). All the parameters have been analyzed with respect to gender. The majority of the esthetic dental and facial measurements were larger in men (p<0.05). The great majority of the participants were completely satisfied with their dental appearance (75% of men and 89% of women; p>0.05). In the men, the two factors of maximal maxillary incisal display at rest and intercommisural width at smile paralleled the variability of the patients' satisfaction with dental appearance by 99% (p>0.05). In women, the combination of central incisor width/length ratio, intercommisural width at rest, central incisor gingival zenith displacement, intercommisural width at smile, upper lip height, and maximum maxillary incisal display at rest paralleled the variability of the patients' satisfaction with dental appearance by 99% (p>0.05). Within the population tested, the results suggest that the use of esthetic dental and facial measurements may serve as an esthetic guideline and should be considered in esthetic anterior oral rehabilitation. The information presented in this article may be useful in helping to create dental restorations with an acceptable esthetic appearance to the patient. Prior to the treatment the dentist should consider not only the size of maxillary anterior teeth but also their gingival architecture and the soft tissue surrounding the teeth.
