Evaluation of the impact of orthodontists' smile with malocclusions on social media and professional credibility.

OBJECTIVES: This study assessed laypeople's perceptions of orthodontist credibility based on malocclusions and whether these views affect their choice to seek treatment. Eye-tracking technology and questionnaires were utilized. MATERIALS AND METHODS: Ninety-five lay raters, through eye tracking and a questionnaire, assessed 12 images of orthodontists with malocclusions. Malocclusions were categorized by the Index Of Treatment Need (IOTN) as grade 1 (near ideal), 3 (anterior crowding), and 5 (with diastemas). Fixation points were recorded, and credibility was gauged via questionnaires. A Mentimeter word cloud was generated. RESULTS: IOTN 1 orthodontists were viewed as more credible than IOTN 3 (p < 0.001) and 5 (p < 0.001). Raters were more willing to receive treatment from IOTN 1 orthodontists. The focus for IOTN 1 was between eyes and mouth, while IOTN 3 and 5 were on the mouth. "Crooked teeth" and "spacing" were predominant in word clouds for IOTN 3 and 5. CONCLUSION: Orthodontists with an IOTN grade 1 rating were perceived as more competent, reliable, and professional, thus making it more likely for laypeople to choose them as their preferred providers. CLINICAL RELEVANCE: The smiles of professionals play a significant role in laypeople's decision to choose them as their orthodontist, and strategic utilization of social media can effectively deliver health information to a larger audience in a faster and more direct manner.

Assessing the reliability of ChatGPT: a content analysis of self-generated and self-answered questions on clear aligners, TADs and digital imaging.

INTRODUCTION: Artificial Intelligence (AI) is a tool that is already part of our reality, and this is an opportunity to understand how it can be useful in interacting with patients and providing valuable information about orthodontics. OBJECTIVE: This study evaluated the accuracy of ChatGPT in providing accurate and quality information to answer questions on Clear aligners, Temporary anchorage devices and Digital imaging in orthodontics. METHODS: forty-five questions and answers were generated by the ChatGPT 4.0, and analyzed separately by five orthodontists. The evaluators independently rated the quality of information provided on a Likert scale, in which higher scores indicated greater quality of information (1 = very poor; 2 = poor; 3 = acceptable; 4 = good; 5 = very good). The Kruskal-Wallis H test (p< 0.05) and post-hoc pairwise comparisons with the Bonferroni correction were performed. RESULTS: From the 225 evaluations of the five different evaluators, 11 (4.9%) were considered as very poor, 4 (1.8%) as poor, and 15 (6.7%) as acceptable. The majority were considered as good [34 (15,1%)] and very good [161 (71.6%)]. Regarding evaluators' scores, a slight agreement was perceived, with Fleiss's Kappa equal to 0.004. CONCLUSIONS: ChatGPT has proven effective in providing quality answers related to clear aligners, temporary anchorage devices, and digital imaging within the context of interest of orthodontics.

Orthodontics social media, perceptions of science- and non-science-based posts among orthodontists, dentists, students and laypeople.

Worldwide, social media is gaining popularity year after year. In Brazil, by 2027, there will be more than 188 million users of social media sites, against 165 million in 2022, therefore, the usage of general population and health care professionals, including orthodontists, is increasing. Differently from scientific journals that undergo a rigorous peer review process prior to publication, the same level of demand is not found on social media. Hence, this study aimed to assess whether orthodontists can recognize scientifically based and non-science-based posts and if their perceptions are different from general opinion (laypeople), dentistry students, and dentists (non-orthodontists). The posts were created using the search tool on Instagram with the hashtags #clearaligners #acceledent #selfligatingbraces and #propelorthodontics, four scientific based posts and four without or with low scientific evidence were selected and evaluated through a virtual questionnaire in the QUALTRICS platform by 385 people, (175 laypeople, 102 dentists, 58 dentistry students, and 50 orthodontists) using a visual analogue scale (VAS). In addition, four questions were asked. ANOVA (Adjusted Bonferroni correction) and Pearson's chi-squared, and Student T tests were applied to identify statistical differences. Significant difference was found only for posts with no scientific evidence between orthodontist's group when comparing with laypeople (p < 0.001) for the #selfligatingbraces, and the #propelorthodontics for the group orthodontists when compared with laypeople (p = 0.031) and dentists (p = 0.033). Instagram was the favorite social media where most of the participants spend more than 3 h. Of the participants, 97% used social media to keep informed and read the news. Almost half of the respondents search for orthodontics services on social media. Orthodontists were able to perceive differences in only two posts from the general perception (laypeople) regarding non- or low-scientific-evidence posts.

The Esthetics of the Nasolabial Fold and Age in the Elderly Via Eye-Tracking.

Background: Facial aging is associated with the loss of soft tissue fullness. Perioral signs of facial aging can add years to individuals' appearances and even affect their facial expressions in smiling and nonsmiling images. Aims: To evaluate the influence of the nasolabial fold on the visual perception of esthetics and age in the elderly, eye-tracking and a visual analog scale were used. Material and Methods: This study applied a cross-sectional study using 40 laypeople. Facial images of an elderly woman were modified to include facial expression lines such as nasolabial folds and marionette lines with no folds, intermediate, and accentuated depths folds. Eye tracking was implemented to measure the average number of fixations. Heat maps and dot maps were generated using eye-tracking software. A visual analog scale of attractiveness and age perception questionnaire were also incorporated into the study. Statistical analysis was performed using a significance of (P<0.05). Results: The majority of visual attention was paid to the eye and mouth areas. In the images with no folds, the right eye attracted a greater degree of fixation. In the images in which nasolabial folds were accentuated, the mouth area served as an area of high fixation. No statistical difference was observed between the groups in which smiling images were viewed. Nonsmiling images demonstrated significant differences between groups for variables including time until first fixation, complete fixation time, and number of fixations on the eyes and hemifaces. Old age and diminished attractiveness were associated with attenuated nasolabial folds, especially in nonsmiling images. Conclusion: The facial lines and expressions of elderly female individuals were assessed by laypeople using eye-tracking, showing that the deeper one's nasolabial folds, the more aged and less attractive one appears, especially in nonsmiling images. Smiling pictures were perceived to be more attractive and youthful; these perceptions should be considered in the search for improved esthetic results, whether in dental or facial esthetic treatments.

The influence of malocclusion on social aspects in adults: study via eye tracking technology and questionnaire.

BACKGROUND: Smile esthetics has a strong influence on perception, attractiveness, and personal characteristics. It is unknown how malocclusions may influence the appearance of the individual's smile. This study aimed to investigate whether malocclusion affects the visual perception of esthetics, age, employability, honesty, intelligence and to meet its obligation in time in middle-aged adults. Facial frontal smiling photographs of a male and a female middle-aged adult with 3 different malocclusions were shown to and evaluated by 90 laypeople (non-dentists), divided into groups: young adults (14-44 years), middle-aged adults (45-59 years), and elders (over 60 years). The index of treatment need (IOTN) was used, and IOTN 1, 5, and 8 images were created in Photoshop using the male and female photographs. In total, 6 photographs were evaluated, 3 areas of interest (AOI)-eyes, nose, and mouth-were created for statistical comparison. The Ogama and Eye Tribe tracker were used in conjunction to measure eye tracking. A visual analog scale (VAS) was employed with a questionnaire surveying individuals' perception of age, employability, honesty, intelligence, and ability to meet obligations. Kruskal-Wallis, one-way analysis of variance, Pearson's-chi-squared, and Pearson correlation test were applied. RESULTS: No statistical difference was found in complete fixation time and time until the first fixation for each AOI for eye-tracking. VAS showed statistical differences in the male and female IOTN 1 images when compared with the IOTN 5 and 8 for both models, and there was no difference between genders in the IOTN 1. As the perceived age of the model increased, the chances of getting hired decreased. Employability, honesty, intelligence, and ability to meet obligations showed higher values for IOTN 1. There were significant differences between age ranges; perception of intelligence in the female IOTN 1 model (p = 0.002) and IOTN 8 model (p < 0.001) and honesty between young adults and middle-aged adults in the male IOTN 1 and 8 images (p < 0.001). CONCLUSIONS: There was a difference between age groups in the perception of honesty and intelligence. A well-balanced and attractive was perceived as more youthful and attractive in both genders and may increase the chance of being selected for a job interview or being hired.

Social attractiveness perception of a cleft lip repair in an adolescent via eye-tracking.

PURPOSE: The present study was designed to investigate the perception of unilateral cleft lip (UCL) repair scar using an image of an adolescent and eye-tracking technology. MATERIAL AND METHODS: Frontal and oblique views of an image of an adolescent with a unilateral upper lip scar result of a corrective surgery. Eighty-five laypeople respondents were divided into three groups: Group A (15-44 years of age); Group B (45-59 years of age); and Group C (≥ 60 years of age). Gaze tracking was carried out to assess the location on the image of greatest fixation, to create dot maps and to follow the trajectory of the gaze. Respondents also assessed six attention questionnaires. The answers and assessment of the VAS were compared. P-values <0.05 were considered significant in the analyses. RESULTS: The central focus of the visualization was concentrated on the upper lip and the region of the nostril, followed by the eyes. Time until 1st fixation upon right lip and mouth showed differences with regard to different images. Images of the model shown in various guises including smiling or not, in a frontal or oblique views showed significant differences in VAS scoring (p<0.001). CONCLUSION: The presence of a scar from the UCL repair in an adolescent was noted in the foreground by laypeople. The scar was associated with a lower degree of attractiveness, happiness, and intelligence, as well as with shyness and sympathy, although a visible scar did not influence the perception of "good hygiene habits".
