“…For the higher scores, orthodontists gave significantly lower scores than prosthodontists and laypersons. This result may be attributed to the fact that orthodontists routinely use facial analysis and smile analysis during treatment planning and diagnosis [ 29 – 31 ], which makes them more critical for identifying smaller levels of deviations compared to other dentistry professionals and laypersons, as shown by previous studies [ 4 , 12 , 13 , 15 , 22 ]. Other studies have shown that orthodontists tend to be stricter in their evaluations and give lower mean scores [ 1 , 4 , 12 , 13 , 18 ].…”

“…Since esthetic treatment procedures frequently involve the anterior esthetic zone and require a multidisciplinary team approach, the different specialists involved should share their knowledge regarding smile esthetics among one another, which would facilitate communication and would improve the treatment outcome [4,11]. There are several studies that have compared the opinions of orthodontists, general dentists, and lay people regarding smile esthetics [1,4,5,[12][13][14][15][16][17][18]. However, to the best of our knowledge, no study has compared the opinions of orthodontists, prosthodontists, and laypersons regarding the vertical positions of anterior teeth and smile esthetics.…”

Background The aim of this study was to assess the esthetic perceptions of orthodontists, prosthodontists and laypersons with regard to different vertical positions of the maxillary central incisors related to lateral incisors for different facial vertical height cases. Subject and methods Frontal full-face photographs showing social smiles of three adult women aged between 18 and 25 years were used. Vertical position of the maxillary central incisor was changed (intruded or extruded) with 0.5 mm increments according to the reference gingival line resulting five images for each woman in a full-face view yielding a total of 15 images. A visual analog scale was placed below each smile to allow the raters to evaluate the attractiveness of each smile independently. One-way analysis of variance was used to determine whether there was a difference between more than two independent groups in terms of quantitative variables. Comparisons of more than two dependent groups were examined with repeated measures one-way ANOVA. The significance level was taken as 0.05 for all analyses. Results For increased facial vertical height, the highest scores for orthodontists were given to the 0.5 mm extruded (64.18 ± 26.36), for prosthodontists to the control (57.28 ± 19.80), and for layperson to the 1 mm extruded (61.27 ± 25.98) central incisor position. For decreased facial vertical height, the highest scores were obtained at the 0.5 mm intrusion with an increasing pattern from orthodontists to laypersons (63.95 ± 22.08 for orthodontists, 79.87 ± 21.43 for prosthodontists, and 79.88 ± 19.17 for laypersons). All three rater groups gave the highest scores to the 0 mm (control) smile design for normal facial vertical height. When these scores were compared among the groups, laypersons gave significantly higher scores compared to orthodontists (p < 0.001) and prosthodontists (p = 0.005). Conclusions The facial vertical height significantly affected the perception of smile esthetics. Keeping the distance between the central and lateral incisors longer than 1 mm in individuals with increased facial height may be important in terms of increasing patient satisfaction in terms of clinical aesthetics. On the contrary, keeping the distance between the central and lateral incisors shorter than 1 mm may create a more esthetically acceptable result in individuals with short facial height.

“…Numerous studies have been undertaken about how laypeople and professionals in dental medicine interpret smiles [ 1 , 2 , 3 , 4 , 5 ]. Kokich et al found that orthodontists, doctors of dental medicine, and laypeople have different perceptions of specific dental esthetic discrepancies [ 3 ].…”

“…They are considered the most pleasing when they are semi-rounded in shape, and this is exactly what is found in conical and ovoid teeth. Squared incisal embrasures are considered un-esthetic, especially among the female population [ 5 ]. When discussing the incisal portion of dental crowns, it is important to note that different people perceive the relationship between the length of the central and lateral incisors differently (incisal step).…”

Background: This randomized trial’s objective was to investigate the impact of social network content on the perception of smiles among specialists, doctors, students of dental medicine, and laypeople. Method: A sample of 360 respondents was shown 7 digitally altered photographs of smiles (85.63% female, 14.37% male). Dental specialists, dentists, dental students (first to third year and fourth to sixth year), and laypeople made up the sample. Respondents were asked to rank the images on a scale of 1 to 10, starting with the least appealing and moving up to the most attractive, using a Google Form. Respondents were divided into experimental and control groups at the end of the following month by random selection. The experimental group followed an Instagram profile posting two images of beautiful smiles for seven days, while the control group received no intervention at all. Both groups then completed the same questionnaire again. The comparison of esthetic scores between the experimental and control group was performed using the Mann–Whitney U-test and the difference in test responses between the starting point of the measurement and after exposure to perfect content on social media within individual groups was tested with the Wilcoxon paired-samples test. When comparing the absolute difference of scores, the Mann–Whitney U-test and the Kruskal–Wallis test were used. Results: Respondents in the experimental group rated the rounded embrasures of the incisors with lower esthetic scores compared to the control group that was not exposed to images on the Instagram social network. In those exposed to Instagram (experimental group), laypeople showed significantly greater satisfaction with their own smile after the exposure to Instagram, whereas no such difference was present in the control group. Conclusions: The content of social networks potentially has an influence on smile perception, most visible in the perception of incisal embrasures and self-perception of smile.

“…Although the tooth is considered to be the basic component of smile design, the "incisal embrasure's" role cannot be overlooked as a smile is more considerably affected by a small change in the embrasures rather than the change in the tooth anatomy itself 4 . Teeth shapes play an important role in esthetics and influence the pattern of the incisal embrasure 5 . Incisal embrasure is the divergence formed by the proximal surfaces of anterior teeth from the contact point initially.…”

OBJECTIVES: To determine the frequency of female dentate patients' most appealing incisal edge embrasure designs. METHODOLOGY: The sample consisted of 385 female dentate patients between 18 to 40 years of age visiting Sardar Begum Dental College and Hospital, Peshawar, from January 2021 to June 2021. The subject's perception was recorded by having the subjects visualize a set of five photographs showing different categories of incisal edge embrasure designs classified by Foulger and Tredwin. The labels of these different photograph categories were obscured using a non-transparent tape, and A, B, C, D, and E; names were assigned to them, respectively, to avoid bias. Means and standard deviations were calculated for quantitative variables like age, while the frequency was calculated in percentage for categorical variables for the most appealing incisal edge embrasure design. RESULTS: The most attractive incisal edge embrasure design amongst the female dentate patients was the "Ideal" design with 33.8%. The second most attractive design displayed "Equal" incisal edge embrasures with 31.4. The "Reversed" and "None" categories had 12.2% and 9.9% percentages. The least attractive design amongst these females was with "Exaggerated" incisal edge embrasures. CONCLUSION: Female dentate patients' most appealing incisal edge embrasure design displays the "Ideal" incisal edge embrasure form.
