Esthetic factors of smile in vertical dimensions: A comparative evaluation
Journal of Indian Orthodontic Society, 2015
Introduction: The variations in aesthetic perception among the professionals and the laypersons were compared, to understand the association of various skeletal and dental factors in vertical dimension, which alter the soft-tissue characteristics during posed/social smile, among young adults. Methods: Images of the posed smile were captured with a digital camera from the 60 nonorthodontic treated young adults (30 girls, 30 boys). Determinants of the "pleasing smile" were identified from the results of a Visual Analog Scale. Quantitative measurements of the soft-and hard-tissue were made by using the smile images and cephalometric radiographs. The esthetics of the smile was correlated with specific skeletal, dental, and soft-tissue structures in the anteroposterior and vertical dimensions. Results: Three factors formed significant components of a pleasant smile, for orthodontists (incisogingival display, upper lip, and buccal corridor) and three for laypersons (upper lip, lower lip, and smile arc). A strong positive correlation was seen among skeletal and dental vertical dimensions and incisor show. The vertical thickness of the upper lip had a significant positive correlation with the position of the maxillary incisor. Conclusion: Incisogingival display, upper lip, lower lip and buccal corridor proved to be the most influential variables in smile esthetics. The significant relationship of incisor protrusion with the vertical thickness of the vermilion border of the upper lip shows that skeletal and dental vertical dimensions for incisal display must be considered when planning orthodontic treatment.

Background: Smile plays a significant role in facial attractiveness and social interactions. The present study aimed to evaluate the smile attractiveness in subjects treated with extraction or non-extraction orthodontic treatment modality. Materials and Methods: Frontal smiling photographs of 100 orthodontically treated subjects with an age range of 16-25 years were taken and divided into two groups each having 50 subjects. Group I (ANB 0° to 4° ) was subdivided into cases treated with extraction (group la) and without extraction (group lb). Similarly, Group II (ANB > 4°) was subdivided into cases treated with extraction (group lla) and without extraction (group lib). Smile esthetics and esthetic scores were assessed on frontal smile photographs by using different smile variables objectively and with the help of raters (10 laypersons,10 dental graduates, and 10 orthodontists) subjectively. Results: In extraction cases, the esthetic scores of dental practitioners and orthodontists...
SMILE AESTHETICS APPRECIATED BY LAYPERSONS
Introduction: The new requirements in orthodontics put emphasis on smile aesthetics and yet there are only a few studies on the analysis of smile components and ideal aesthetic smile norms. Methodology: A lot of 80 pacients has been selected and photos of their smile have been taken. From this photos, 19 pictures have been selected for the smile components they posses and analyzed. There were taken 3 photos for the parallelism of the smile arch with the lower lip; 3 photographs for free margin of the upper lip mucosa; 3 photographs for the anterior height of the smile; 4 photographs for the last maxillary visible tooth in smile; and another 3 photographs for the percentage of the bucal corridor. These photographs have been analyzed by a group of 150 laypersons who have appreciated the esthetics of these photos choosing the most aesthetic and the most unaesthetic of each component. Results: The parallelism between the smile arch and the inferior lip line, the horizontal linear smile,the medium height of anterior and posterior smile, the last visible maxillary tooth in smile- second premolar and a medium bucal corridor are the most aesthetic smile options. The most unaesthetic variants were considered: a reverse smile arch, a concave smile, a gummy smile,the last visible maxillary tooth in smile- first molar and a large bucal corridor. Conclusions: The study aim is to establish some dynamic norms for smile aesthetics components. Keywords: smile, aesthetic, buccal corridor, smile arch, gingival display.
Perceptions Differences in Smile Attractiveness Between Dental Students’ and Lay Persons’
2021
Introduction: Orthodontic treatment is performed to improve dental alignment, function, oral health, dentofacial stability and to achieve better facial esthetics. People tend to seek orthodontic treatments for a more esthetically attractive smile. Several parameters are used to measure the attractiveness of smiles, including the smile arc, smile line, buccal corridor or smile type, and smile symmetry. Perceptions of the various aspects of smile attractiveness may differ among patients and dentists, so dentists must understand patients’ perceptions of the aspects of smile attractiveness in order to provide satisfactory care. Objective: To determine if there are differences in the perceptions of dental students and lay persons regarding the aspects of smile attractiveness. Methods: This is an analytical observational study with a cross-sectional research design. This study was conducted by distributing questionnaires containing 11 photographs of manipulated smiles to 50 students curre...
Comparison of perceptions of laypersons, dentists and orthodontists to altered smile aesthetics
Pakistan Orthodontic Journal, 2016
Introduction: Smile plays an important role in facial expression. Esthetic perception varies from person to person, therefore what is beautiful for orthodontist might not be attractive for the patient. So the responsibility on the orthodontist is to create a smile which seems beautiful to the patient and is acceptable to the society and to the laws of esthetics as well. Material and Methods : This study was conducted in Islamic International Dental Hospital Islamabad in the department of orthodontics from April 2015 to June 2015. It was a cross sectional descriptive study. A colored photograph of a female with well aligned smile was selected and was modified using ABOBE 7.0. Two variables for evaluation were considered, gingival exposure and midline shift. Two sets of pictures included 9 images in total were shown to the 3 panel groups; orthodontists (n=52), dentists (n=60) and lay persons (n=60). The modified images were scored using a 5 point visual analogue scale (VAS) with 0 in...

Introduction: Living in a beauty conscious society, the mouth, a focal point of the face, plays a major role in how we perceive ourselves and in the impression we make on the people around us. Esthetic perception varies from person to person, being influenced by each person's personal experience and social environment. In the process of providing esthetic treatment for a patient, one should not only rely on one's eyes and personal perception of beauty, but also be guided by the patient's desires. Hence, the measurement of the perception of beauty in dentistry is fundamental for providing scientific data that can guide diagnosis and treatment planning. Aim: This study aims at evaluating the changing trends of esthetic dentistry with the perception of people. Materials and methods: The study using a visual pictorial questionnaire was conducted among 100 students of

Background: The aim of this study was to determine the perception of smile esthetics among orthodontists and laypeople with respect to the presence of diastemas in the upper lateral incisor in the mesial, distal, and both surfaces using an oblique smile analysis. Methods: Two standardized oblique photos of pleasant smiles from two white women were selected. Images were digitally altered to create diastemas in the lateral incisor, in 0.5-mm increments, in the mesial, distal, or both surfaces. Final images were randomly assembled in a photo album, which was given to 120 judgesd60 orthodontists and 60 laypersons. Each rater was asked to evaluate the attractiveness of the images on a visual analog scale. The data collected were submitted to statistical analysis by the means of one-way ANOVA with the Tukey post hoc test and the unpaired Student's t test. Results: The most attractive smile was the one without spacing, and the presence of diastemas was considered unattractive by both groups of raters, following a pattern: the greater and the more mesially located, the more unattractive was the smile. Conclusions: The results of this study suggest that diastemas in the upper lateral incisor area were considered unattractive, following a pattern: the greater and the more mesially located, the more unattractive was the smile.
