Impact of Dental Midline Shift on the Perception of Facial Attractiveness in Young Adults.

Background/Objectives: The aim of this study was to quantify the threshold of a dental midline shift that would compromise facial attractiveness and indicate a need for treatment from the points of view of laypeople and dental professionals. Methods: Whole-face natural photographs of a male and a female model were digitally manipulated to create various degrees of upper and lower dental midline shifts through bodily movement of the upper or lower midlines as well as alteration of the axial inclination of the upper teeth. The samples were then assessed by two groups of observers (laypeople (LP) and dental professionals (DP)). Results: The lower midline shift did not negatively affect the DP and LP's perceptions of smile attractiveness. The first significant loss of attractiveness was registered by the DP with an upper midline shift of 1 mm in the female model. However, the LP registered this at 2 mm. The DP registered the necessity of treatment at a threshold of 2 mm in the female model and 3 mm in the male model. LP identified the need for treatment at 3 mm for both males and females. The female model was judged more critically than her male counterpart by both female and male observers. Conclusions: DP assess the midline deviation more critically than LP. Both DP and LP were more sensitive to midline deviations in the female model regardless of their own gender. Both groups registered the need for treatment at a higher threshold than the reduction in smile attractiveness.

Truth Lies in the Depths: Novel Insights into Facial Aesthetic Measurements from a U.S. Survey Panel.

Aesthetic facial bone surgery and facial implantology expand the boundaries of conventional facial surgery that focus on facial soft tissue. This study aimed to reveal novel aesthetic facial measurements to provide tailored treatment concepts and advance patient care. A total of n=101 study participants (46 females and 55 males) were presented with 120 patient portraits (frontal images in natural head posture; 60 females and 60 males) and asked to assess the facial attractiveness (scale 0-10; "How attractive do you find the person in the image?") and the model capability score (MCS; scale 0-10; "How likely do you think the person in the image could pursue a modelling career?"). For each frontal photograph, defined facial measurements and ratios were taken to analyse their relationship with the perception of facial attractiveness and MCS. The overall attractiveness rating was 4.3 ± 1.1, while the mean MCS was 3.4 ± 1.1. In young males, there was a significant correlation between attractiveness and the zygoma-mandible angle (ZMA)2 (r= - 0.553; p= 0.011). In young and middle-aged females, MCS was significantly correlated with facial width (FW)1-FW2 ratio (r= 0.475; p= 0.034). For all male individuals, a ZMA1 value of 171.79 degrees (Y= 0.313; p= 0.024) was the most robust cut-off to determine facial attractiveness. The majority of human evaluators (n=62; 51.7%) considered facial implants a potential treatment to improve the patient's facial attractiveness. This study introduced novel metrics of facial attractiveness, focusing on the facial skeleton. Our findings emphasized the significance of zygomatic measurements and mandibular projections for facial aesthetics, with FI representing a promising surgical approach to optimize facial aesthetics.

The role of attention in the effect of facial attractiveness on time perception.

Recent research has indicated that attractive faces often cause a dilation of our time perception thus affecting physical and mental health, and speculates that this could be relevant to the fact that attractive faces capture people's attention.Nevertheless, there was no direct experimental data to support this speculation. The present work was designed to illustrate how attention affects time perception of facial attractiveness. It utilized two experiments to investigate this phenomenon. In Experiment 1, perception of timing and attention bias were assessed using a temporal reproduction task and a dot-probe task. Increased attention bias was found to mediate the time dilation effect of facial attractiveness. Experiment 2 adopted dual-task paradigm, combining a temporal reproduction task and attractiveness rating task, to manipulate attention allocation. The findings suggested that allocating more attention to the task requiring timing enhanced the time dilation effect caused by the faces. Results of Experiments 1 and 2 converge to show that attention plays an essential role in the effects of facial attractiveness on time perception.

Evaluation of the Influence of Nasolabial Angle, Upper Sulcus Depth, and Nasal Tip Protrusion in the Perception of Facial Attractiveness

ABSTRACT Objective: To evaluate the influence of variations in the upper sulcus depth, nasal tip protrusion, and nasolabial angle on the esthetic perception of profiles. Design: A web-based survey study and was conducted in the Department of Orthodontics and Dentofacial Orthopaedics. This survey was conducted for a period of 10 months and included orthodontists practicing in India. Methods: This study included lateral cephalograms of the most esthetic profiles from a set of 30 profiles that were within Holdaways norms; the most esthetic profile was determined by a panel of two orthodontists and two general dentists. The most esthetic profile photograph will be transferred to a computer in Corel software. The outline of the profile will remain the same, with the inner aspect converted into a dark area (black); now, the profile is completely converted into facial silhouettes. This black facial silhouette is presented to avoid any distractions and bias. There will be a total of 27 silhouettes by various combinations of increased, decreased, and normal values for nasolabial angle, upper sulcus depth, and nasal tip protrusions. Results: Both the orthodontist and layman chose the most favored profile as a normal profile having a normal nasal tip, normal nasolabial angle, and normal upper sulcus depth, whereas among dentists, 50% chose the most favored profile in which the nasolabial angle was normal but the nasal tip and upper labial sulcus were decreased. When it comes to the least favored profiles, opinions varied between orthodontists, dentists, and laymen. Conclusion: The perception of facial esthetics has always been and still is varied between the layman, the dentist, and the orthodontists. Profiles with normal to sharp noses with normal and increased nasolabial angles were considered more attractive than the others. Profiles with fuller upper labial sulci were considered least attractive with other parameters changing.

Comparison of perception on facial profile attractiveness of different antero-posterior proportions in a female subject among laypersons, dentist and orthodontists: An observational study

: Current Orthodontic diagnosis and treatment plan is based on the arrangement of the soft tissue complex. This makes the execution of treatment plan very challenging as beauty is a subjective factor leading to different facial evaluations. This study aims at comparing and evaluating the perception of facial attractiveness of different antero-posterior proportions of the chin which was altered digitally in a female subject among laypersons, dentists and orthodontists. A digital profile photograph of a 26 year old female subject was selected for the study. The subject was randomly selected from the Department of Orthodontics and Dentofacial Orthopaedics, Institute of Dental Sciences & Sum Hospital, Bhubaneswar, Odisha and was advised for pre-treatment Orthopantomogram, Lateral Cephalogram. The profile image was digitally altered using Adobe Photoshop software to create 11 images which was given to 10 Orthodontists, Dentists and laypersons for evaluation of their perception of facial profile attractiveness on a VAS scale. A straight profile in a female subject is perceived as the most attractive by all the three categories of evaluators. It can be concluded that this study provides a basis for understanding facial profile preferences by different groups of people as well as their degree of sensitivity.

Occlusion of faces by sanitary masks improves facial attractiveness of other races.

Recent studies provide mixed results regarding whether the perception of facial attractiveness is increased or decreased by partial occlusion with a sanitary mask. One set of studies demonstrated that occluding the bottom half of a face increased facial attractiveness. This effect is thought to occur because the occluded area is interpolated by an average facial representation that is perceived as attractive. However, several groups of studies showed that partial occlusion can increase or decrease perceived attractiveness depending on the attractiveness of the original (unoccluded) face, due to regression to the mean. To reconcile this inconsistency, we propose that the occluded area is interpolated not by an average facial representation, but by a template of moderate attractiveness, shaped by the distribution of each viewer's experience. This hypothesis predicts an interaction between occlusion and the attractiveness of the original face so that occluded attractive faces are rated as less attractive, while occluded unattractive faces are rated as more attractive. To examine this hypothesis, the present study used attractiveness-rating tasks with mask-free versus masked faces in own-race and other-races categories. Viewers were familiar with own-race faces and unfamiliar with other-races faces. If moderate-attractiveness interpolation were the explanatory factor, the interaction between the occlusion and the attractiveness of the original face should be found only in the rating of own-race faces. Consistent with this hypothesis, the interaction between the occlusion and the attractiveness of the original faces was significant only for the own-race faces. Specifically, wearing a sanitary mask decreased the facial attractiveness of attractive faces in the own-race, while it increased the attractiveness regardless of the level of facial attractiveness in other-races. These findings suggest that the occluded area of own-race faces is interpolated by a facial template of moderate attractiveness. The other-races template could be developed using familiar exemplars such as celebrities. Thus, interpolation by such a template should result in elevated attractiveness relative to that by an own-race template. Accordingly, the apparent inconsistency in the literature regarding the effect of partial occlusion on physical attractiveness can be explained in terms of differences in the template involving interpolation of the occluded area.

Background. Many studies have been devoted to the relationship between the perception of facial expression and emotional intelligence (EI). As a rule, the study of this issue involved the tasks of expression recognition with stimuli expressing strong basic emotions. However, diX erences in the success of expression recognition in groups with diX erent levels of EI are not always signiY cantly pronounced. Z is may be connected to the fact, that the recognition of basic expressions is too easy for subjects with both high and low EI scores. In order to conduct a more effective study of this issue, it is necessary to complicate the task of facial expressions recognition. To this end, one of the conY gurational eX ects of E. Brunswick stating that neutral faces with diX erent conY gurations of facial features are perceived as emotionally colored, can be used. Under these conditions, a more adequate task is not to assess the success of expression recognition, but to assess the attractiveness of the face, which is closely related to the perceived facial expression. Z us, faces with positive expressions are more o[ en rated as attractive, and vice versa. It is assumed that the study of the perception of neutral faces will reveal the features of the relationship between the perception of facial expression and EI. Objective. Z e study is meant to explore the relationship between the perception of facial attractiveness and EI. It was assumed that subjects with diX erent levels of EI would evaluate the attractiveness of neutral faces diX erently. Sample. Z e experiment involved 49 people (20 men and 29 women, in the age range of 18–35 years). Methods. Images of faces were presented on a monitor screen. Eye movements were recorded during stimuli presentation. Z e level of EI was assessed based on the results of the “Test of emotional intelligence” (TEI) (Sergienko et al., 2019). We calculated indicators of TEI for all branches of EI (the abilities to recognize, understand, manage, and use emotions), as well as the total score of EI. An analysis of face attractiveness scores as well as eye movement parametres (duration and number of Y xations, duration of saccades) was carried out for two groups of subjects with high and low EI scores.

My group is more important than yours in the Cheerleader Effect of facial attractiveness perception

Your face looks the same as before, only prettier: The facial skin homogeneity effects on face change detection and facial attractiveness perception.

Previous studies suggested that (1) facial attractiveness perception can be increased with facial skin homogeneity improving; and (2) human's facial change detection increases along with facial skin homogeneity increases. However, it's unknown whether a face can be perceived prettier than it did before while still being considered as physically the same. It is possible that these two kinds of cognitive-aesthetic processing may have separate mathematical functions in psychophysical studies. In other words, human's facial attractiveness differentiation may be more sensitive than facial change detection. In this current study, we explored the above questions. Using three types of psychophysical techniques to manipulate facial skin homogeneity, we measured how participants' sensitivity to facial skin homogeneity and attractiveness change. Results showed a linear function curve for facial physical change detection and a logarithmic function curve was drawn in the forced-choice technique, which was the most sensitive one, indicating that participants can judge a face prettier than before without being aware of it has physically changed. Besides, two linear function curves were shown in the same/different technique and a rating technique. Taken together, this current study revealed that facial attractiveness can be enhanced and discriminated by improving facial skin homogeneity, without being realized by people with conscious awareness that the face has been changed.

Is a symmetrical face really attractive?

Facial symmetry plays an important role in facial attractiveness and is one of the major criteria used to determine attractiveness in humans. In craniomaxillofacial surgery, facial symmetry is one of the main considerations. The aim of this study was to determine anthropometric measurements quantitatively and investigate the relationship between facial symmetry and attractiveness in a local Malay population. The study included 30 photographed Malay individuals and 100 photograph assessors, all aged between 18 and 26 years. The assessors indicated their preferences regarding the more attractive face on original and manipulated (symmetrical face) photographs. None of the photographed subjects had a perfectly symmetrical face (asymmetry index (AI) of 0%); 33.3% of the photographed subjects had an AI in the range of 1.6–2.0%. The majority of assessors chose the manipulated symmetrical face as the most attractive (manipulated photograph selected in 91.2% of cases). As facial symmetry is considered a critical factor in attractiveness, it is beneficial to consider balance and symmetry prior to facial reconstruction. The AI values found in this study may be useful as guidance to determine the normal minimum balance of facial symmetry. No AI values indicating perfect symmetry were observed for the unedited facial anthropometric measurements. However, the projection of a perfectly symmetrical face does influence the perception of facial attractiveness.

A CBCT Evaluation of Esthetic Preference Regarding the Perceived Facial Attractiveness of Young Korean Female Adults with a Normal Skeletal Pattern.

The aim of this study was to determine the factors that affect esthetic preference regarding the perceived facial attractiveness of young Korean female adults with a normal skeletal pattern using cone-beam computed tomography (CBCT). After reorienting the CBCT images of 40 young Korean female adults, three-dimensional (3D) measurements were analyzed, and five 3D facial images were digitally constructed. A computer-based questionnaire was used to determine perceived facial attractiveness by scoring from 1 (very unattractive) to 10 (very attractive). Esthetic perception and the most influential facial view and component were examined and compared by orthodontists, general dentists, and laypeople to evaluate facial attractiveness. Compared to the unattractive group, the attractive group had significantly greater values for Pog-NB, L1SI-FH, U lip thickness, L lip-U lip, and Nasolabial angle, along with significantly lower values for U1SI-FH and Cant of U lip; the attractive group also had a more retruded U1MP (p < 0.01), L1MP (p < 0.01), U lip (p < 0.05), and L lip (p < 0.01) relative to N, as well as a more retruded U lip (p < 0.05) and L lip (p <0.001) relative to esthetic lines. Orthodontists and general dentists were more likely to consider the profile view. When evaluating facial attractiveness, orthodontists and laypeople more often focused on the lips and chin. When evaluating facial attractiveness, all evaluators showed a high esthetic preference for retroclination and retrusion of the incisors and lips, but there were some differences in how they perceived facial attractiveness. Therefore, the ultimate perception of facial attractiveness needs to be based on the esthetic perceptions of laypeople.

Dominance or Integration? Influence of Sexual Dimorphism and Clothing Color on Judgments of Male and Female Targets' Attractiveness, Warmth, and Competence.

The face is an important source of information in social interactions. Prior studies exploring the mechanism of face perception were consistent with either dominance or integration theory. Studies have shown that both sexually dimorphic features and background cues play essential roles in the formation of impressions and the perception of facial attractiveness. In this study, we conducted two experiments to examine 539 participants’ appraisal of attractiveness, warmth, and competence of the target faces of masculine and feminine men and women dressed in red, blue, or white. The results showed that: (1) feminized male/female faces were considered to have a higher degree of attractiveness, warmth, and competence, (2) people rated feminine faces wearing red higher in terms of attractiveness perception, while there was no significant effect of red on attractiveness perception of masculine faces, (3) when evaluating the warmth of targets, the promotion effect of red was found for feminine faces but not for masculine faces. This study, conducted in a pathogen disgust environment, provides direct evidence to support the integration theory over the dominance theory. Feminized red preference found in this study matches Chinese collectivism and the red cultural heritage, which has an important value for people's daily impression management and consumption decisions.

Investigating the Crossmodal Influence of Odour on the Visual Perception of Facial Attractiveness and Age.

We report two experiments designed to investigate whether the presentation of a range of pleasant fragrances, containing both floral and fruity notes, would modulate people's judgements of the facial attractiveness (Experiment1) and age (Experiment2) of a selection of typical female faces varying in age in the range 20-69 years. In Experiment1, male participants rated the female faces as less attractive when presented with an unpleasant fragrance compared to clean air. The rated attractiveness of the female faces was lower when the participants rated the unpleasant odour as having a lower attractiveness and pleasantness, and a higher intensity. In Experiment2, both male and female participants rated the age of female faces while presented with one of four pleasant fragrances or clean air as a control. Only the female participants demonstrated a crossmodal effect, with the pleasant fragrances inducing an older rating for female faces in the 40-49-years-old age range, whereas a younger rating was documented for female faces in the 60-69-years-old age range. Taken together, these results are consistent with the view that while the valence of fragrance (pleasant versus unpleasant) exerts a robust crossmodal influence over judgements of facial attractiveness, the effects of pleasant fragrance on judgements of a person's age appear to be less reliable. One possible explanation for the differing effect of scent in the two cases relates to the fact that attractiveness judgements are more subjective, hedonic, and/or intuitive than age ratings which are more objective, cognitive-mediated, and/or analytic in nature.

Evaluation of normal distribution of palpebral fissure among the medical and paramedical students of Eastern Nepal

Background: The palpebral fissure (PF) is the space between the upper and lower eyelids when the eye is open. The bilateral orbital region which is located in the face acts as one of the important determinants in the perception of facial attractiveness, youthfulness, and health conditions of the individuals. The PF dimensions may get altered in cases of facial deformities and road traffic traumas. Aims and Objectives: The aim of this study was to analyze the mode of distribution of PF dimensions in medical and paramedical students in correlation with gender. Materials and Methods: The study was a cross-sectional study conducted in the duration of August 2021–November 2021 including the sample of 300 medical and paramedical students in an equal number of male and female of age group 16–22 years from Nobel Medical College Teaching Hospital, Biratnagar, Nepal. We measured the dimensions of PF during the normal gaze. The data analysis was done using the SPSS version 16. Results: The mean length of PF (LPF) in males and females was 23.24 mm and 22.72 mm, respectively. The mean height of PF (HPF) in male and female was 8.52 mm and 8.60 mm, respectively. The difference between males and females LPF and HPF was significant(&lt;0.05). The mean PF index (PFI) in male and female subjects was, respectively, 37.20 and 38.68 which were statistically significant. Conclusion: It was found that the LPF and HPF were more in males and PFI was slightly more in females than the male which confirmsthe sexual dimorphism. The data obtained will be helpful in the esthetic consideration of the student’spersonality as well.

Vulnerability of facial attractiveness perception to early and multi-year visual deprivation.

Judgments of facial attractiveness invariably accompany our perception of faces. Even neonates appear to be capable of making such judgments in a manner consistent with adults. This suggests that the processes supporting facial attractiveness require little, if any, visual experience to manifest. Here we investigate the resilience of these processes to several years of early-onset visual deprivation. Specifically, we study whether congenitally blind children treated several years after birth possess the ability to rate facial attractiveness in a manner congruent to normally sighted individuals. The data reveal significant individual variability in the way each newly sighted child perceives attractiveness. This is in marked contrast to data from normally sighted controls who exhibit strong across-subject agreement in facial attractiveness ratings. This variability may be attributable, in part, to atypical facial encoding strategies used by the newly sighted children. Overall, our results suggest that the development of facial attractiveness perception is likely to be vulnerable to early visual deprivation, pointing to the existence of a possible sensitive period early in the developmental trajectory.

Ricketts' E-line profile preferences among Nigerian orthodontists, orthodontic trainees, and a young undergraduate students' population.

This study compared the perceptions of orthodontists, orthodontic trainees, and young university undergraduate students in Nigeria regarding facial profile attractiveness and the need for orthodontic treatment. We used a photo-editing software to alter the lips on Ricketts' esthetic line (E-line) in a lateral silhouette to produce five silhouette profiles with 2 mm incremental changes in the upper and lower lips from the 'normal' position on the E-line (-4 mm/-2 mm to + 4 mm/+6 mm). Two hundred and thirty-two participants (consisting of six groups) ranked the five profiles on a 5-point Likert scale (least attractive, 1 to most attractive, 5). Participants also assessed whether orthodontic treatment was needed to improve facial esthetics. Data were analysed in SPSS 20. Intra-rater reliability was assessed using Cohen's Kappa. We tested the null hypothesis (P ≤ 0.05) that ranked preferences between groups using the Kruskal-Wallis test. Mann-Whitney U test was also used to assess pairwise comparisons between the groups. Intra-rater reliability for facial profiles and treatment needs were moderately acceptable (perceptions ≥67.7%; treatment needs ≥67.0%). Perceptions between orthodontists and orthodontic trainees were not significantly different. However, orthodontists/trainees tended to rank the 'normal' Ricketts' E-line profile as most attractive, while students preferred more protrusive lips. Participants' age rather than sex significantly influenced esthetic preferences. About one-half of all participants (46.6%) ranked the 'normal' Ricketts' E-line as unacceptable; hence required orthodontic treatment to improve their facial attractiveness. Clinical/professional judgment and age significantly influenced participants' perceptions of facial attractiveness. Most participants preferred slightly protrusive lips.

Visualization of Facial Attractiveness Factors Using Gradient-weighted Class Activation Mapping to Understand the Connection between Facial Features and Perception of Attractiveness

Numerous studies in recent years have focused on the prediction of attractiveness using facial features. Researchers have reported high prediction accuracies using convolutional neural networks (CNNs). In this study, a model was built for predicting the attractiveness of faces using a CNN. In addition, the constructed model is used to visualize the features that underlie the prediction of attractiveness values using the gradient-weighted class activation mapping technique, and the trends are compared with a saliency map applying spectral residual and fine-grained methods. In addition, the relationship between image features that are important for attractiveness and facial features that affect human perception of attractiveness are discussed based on earlier findings in the field of psychology. The results support the psychological finding that sexual dimorphism influences the perception of facial attractiveness, a feature that is important for attractiveness prediction. The approach used here can help us understand the connection between facial features and the perception of attractiveness.

Predicting attractiveness from face parts reveals multiple covarying cues.

In most studies of facial attractiveness perception, judgments are based on the whole face images. Here we investigated how attractiveness judgments from parts of faces compare to perceived attractiveness of the whole face, and to each other. We manipulated the extent and regions of occlusion, where either the left/right or the top/bottom half of the face was occluded. We also further segmented the face into relatively small horizontal regions involving the forehead, eyes, nose, or mouth. The results demonstrated the correlated nature of face regions, such that an attractiveness judgment for one face part can be highly predictive of the attractiveness of the whole face or the other parts. The left/right half of the face created more accurate predictions than the top/bottom half. Judgments involving a larger area of the face (i.e., left/right or top/bottom halves) produced more accurate predictions than those derived from smaller regions, such as the eyes or the mouth alone, but even the smallest and most featureless region investigated (the forehead) provided useful information. The correlated nature of the attractiveness of face parts shows that perceived attractiveness is determined by multiple covarying cues that the visual system can exploit to determine attractiveness from a single glance.

Decision Making Capacity or How to Accept Patient’s Refusal for Orthodontic Treatment

Introduction: Communication in dentistry is bilateral process which usually is based on response (understanding) by the person. That’s why the Oral Healthcare Providers (OHP) should be convinced the consent given by the patient is valid. It means that at the beginning of the treatment the orthodontist will ask a lot of questions and have expectations to receive appropriate answers. There is a specific lack of awareness about the first orthodontic consultation at 7y of age, occurrence and prevention of most of the common tooth jaw discrepancies which affect the oral health, self-confidence and overall development of the child. A variety of socio-demographic, educational, personal and other factors mostly divided into objective and subjective factors influences the perception of facial attractiveness. The orthodontic treatment lays down on the personal desire and attitudes, depends from the motivation but is not without a risk for the patient. The aim of the current research is to present the most objective and subjective factors identifying the patient’s refusal. Material and methods: It’s a case report based on preliminary discussion and orthodontic consultation over the cephalometric analysis and cast models. Orthodontic treatment protocol was followed and given informed consent by the individual was received. Results and discussions: An electronic search was conducted using the Medline database (PubMed), Science Direct, and Scopus. In this case report were described the treatment options for Class III malocclusion with an emphasis on maxillary protraction and existing impacted canine 13. The decision making capacity was evaluated and also what are the objective and subjective factors and how to proceed with patient refusal. Conclusions: Despite the orthodontist’s efforts to improve the management of the dental practice and to attract new patients, these challenges should never been from the first importance. Contemporary dentistry requires that the patient’s right to refuse should be respected and this refusal must be accepted. Because orthodontic treatment is expensive, the process of returning money or sharing responsibility for the treatment depend on the socio-cultural characteristics of both the patient and the doctor. The whole situation requires a very delicate approach, as it affects the image of the dental community in society at whole.
