Abstract

Background and Aims: Dental aesthetics has become an important issue in contemporary society. This study was designed to evaluate the patients’ satisfaction with their dental appearance and tendency to improve dental aesthetics.
Materials and Methods: In this descriptive study, a questionnaire with 17 questions was used to collect data from 200 patients referred to the dental school of Isfahan University of Medical Sciences from April-July 2019. A valid and reliable self-administrative questionnaire consisted of questions about the appearance of anterior teeth, receiving cosmetic treatments, and favorite aesthetic dental treatments was designed and used. Data were fed into SPSS22 and analyzed by Mann-Whitney, Kruskal Wallis and Spearman correlation tests (α=0.05).
Results: Among the participants, 27.5% (n=45) were dissatisfied with the appearance of their anterior teeth and the major reason for this dissatisfaction was related to the tooth color (35.8%, n=71). It was also observed that approximately 84% (n=168) of the patients had a history of smile concealment because of their teeth appearance. Among cosmetic dentistry treatments, aesthetic restorations were more commonly used than other treatments (20.5%, n=41). However, the most desired cosmetic treatments were teeth whitening (78.4%, n=156). There was no significant relationship between the satisfaction with the appearance of teeth and interest in the orthodontic treatment with age and education level (P=0.6).
Conclusion: Teeth color was the most important factor determining the degree of satisfaction with the appearance of teeth. Most of subjects desired to receive an aesthetic dental treatment and teeth whitening was the most popular aesthetic dental treatment.

Abstract

Background and Aims: The display of an individual's teeth varies in different facial expressions, which significantly affects the beauty of the lower face and overall appearance. The ideal display of incisors is influenced by lip morphology and is an essential aspect of treatment planning. This study aimed to evaluate the ideal display of incisors at rest in women with different lip forms, as assessed by dentists and laypeople.
Materials and Methods: This was a cross-sectional study that was conducted in 2024 at Babol University of Medical Sciences. 46 dentists and 92 laypeople were selected and included in the study in an easy and accessible way. The distance between the uppermost area from the lower edge of the vermilion of the upper lip to the imaginary line between the two commissures was used to classify the lip shape, which was divided into three categories: straight (0-3 mm), medium (3-6 mm) and long (more than 6 mm). Smile images of three women in the age range of 15-30 years were collected and manipulated, resulting in six new images from each original image with varying degrees of incisor display using Photoshop (a total of 18 images). The designed images were randomly placed in a booklet and given to participants, who scored each image on a scale of zero to 100. The data were analyzed by SPSS software version 22 and using the Mann-Whitney test at a significance level of 0.05.
Results: A total of 138 participants took part in the study, including 46 dentists (33.3%), comprising 17 males (37%) and 29 females (63%), and 92 laypeople (66.7%), including 46 males (50.0%) and 46 females (50.0%). Laypeople gave higher scores to images of straight and moderate lip forms than dentists. However, this difference was not statistically significant (P>0.05). In addition, dentists gave significantly higher scores to all images related to the  long lip form than laypeople (P<0/05). In addition, among laypeople, men gave a higher score than women to images related to straight and moderate lip form, which was statistically significant (P<0.05).
Conclusion: The findings of this study indicated that a 2.5 mm incisal display at rest was suitable for patients with a straight lip form. In general, it can be concluded that by changing the shape of the lip from straight to long, there is a preference for increasing the amount of incisal display in the resting state.
