User Insights into Fake Snap-on Veneers: Perceptions and Experiences.

The aim of this pilot study was to assess the knowledge and perceptions surrounding the use of fake snap-on veneers, as well as to evaluate the experiences of individuals who have used them. This study was conducted between October 2021 and January 2022. A questionnaire was distributed through social media platforms to individuals aged >18 years in Saudi Arabia, which assessed their personal and sociodemographic information and perceptions and experiences with fake snap-on veneers. The statistical analyses included descriptive statistics, bivariate analyses, and multiple logistic regressions. The study included 466 participants, with the majority being young adults, with an almost equal sex distribution. The study highlighted a general reluctance to use these veneers because of concerns about dental damage and esthetics. Women and younger individuals showed higher awareness, and regional variations indicated potential cultural influences on the perception of these dental devices. Most users experienced discomfort and did not recommend the fake snap-on veneers. This study sheds light on a cautious approach toward fake snap-on veneers, despite their esthetic appeal. This underscores the need for strict regulations, public awareness campaigns, and ethical dental practices to ensure informed decision-making and safeguard dental health. The concept of an ideal smile has led to various cosmetic dental procedures. Snap-on veneers offer a pain-free and affordable solution, but fake versions raise concerns about discomfort, unrealistic results, and oral health issues. User complaints emphasize the need for strict regulations and public awareness campaigns to ensure informed decisions.

Dental Aesthetic Perception of Dentistry Students: A Literature Review

The appearance of a smile has increasingly become a factor that significantly impacts an individual's self-esteem and social context. Consequently, there is a growing desire for changes in the oral region to achieve what is considered an ideal smile, particularly in light of new beauty standards, where white and aligned teeth are deemed highly relevant. However, the concept of beauty is highly subjective, and sometimes dental standards do not align with patients' aesthetic desires. This study aims to evaluate the dental aesthetic perception of dentistry students through an integrative review. For the reference framework, we searched articles from the PubMed and Lilacs databases from the past five years, using the keywords "Dental esthetic," "dental student," and "Smiling," with the Boolean operator "and." After a thorough reading of all the articles, nine studies were selected. This review showed that the level of education and gender presented differences in the perception of dental aesthetics. However, students generally agree that aesthetics must be associated with the health and naturalness of the smile, following dental anatomy, dental alignment, buccal corridor, level of gingival exposure, and color.

Aesthetic crown lengthening

Ideal smile aesthetics includes ‘pink’ aesthetics and aesthetic crown lengthening surgery is an integral surgical procedure that is commonly used to achieve optimal overall aesthetics. Understanding the reasons for a ‘gummy’ smile, or gingival excess, is key. A thorough assessment and careful treatment planning are required for successful results. Crown lengthening can be carried out as a stand-alone procedure or as part of a wider restorative treatment plan. CPD/Clinical Relevance: This article discusses the ideal ‘pink’ aesthetics, indications for crown lengthening as well as the treatment sequence.

A Photographic Assessment of Smile by Modifying Crown Height, Width and Angulation of Maxillary Lateral Incisor among Orthodontic Patients of Karachi, Pakistan

Abstract: Background: Smile aesthetics vary culturally, influenced by media and the Golden Proportion in dental beauty. Challenges arise with missing lateral incisors, treated through composite build-up or canine substitution, highlighting the importance of crown dimensions and the need for clinician expertise in personalized treatments. Objectives: The objective of the study is to evaluate the influence of altering height, width and angulation of maxillary lateral incisors on the perception of smile. Materials and Methods: This cross-sectional study was conducted at OPD of Jinnah Medical and Dental College, Karachi from January 2020 to June 2020, on 120 orthodontic patients (44 males and 76 females) aged between 15 and 35 years. Photoshopped photographs of an ideal smile were shown to the participants. In an ideal smile photo, the width of lateral incisor was 62% of the width of maxillary central incisors. The pictures showed to the participants had modifications in terms of crown heights, width and angulation of only maxillary lateral incisor without doing any changes to the other maxillary teeth. The responses of the participants were graded on the basis of perception of attractiveness. Result: Mean score for height, width and angulation changes were obtained. The highest score by males was given to lateral incisor whose length was increased by 1mm (6.87±2.21) and in females; the highest score was given to lateral incisor which is modified by adding 0.5 mm increment (6.98±1.05). Both males and females preferred narrow lateral incisors as esthetically attractive. The mean highest scores for the decrease in width given by males were 6.52±2.52 and 6.8±2.217 by females, respectively. Both males (6.37±2.18) and females (6.64±1.81) preferred 10 degrees of mesial angulation of lateral incisor as more esthetically pleasing. Changes in distal angulation of more than 5 degrees are considered unattractive by both genders. Mean values were 6.04±2.15 for males and 6.00±1.99 for females. Conclusion: In conclusion females are more concerned to the change in height, while in terms of width both genders preferred narrower maxillary lateral incisors over wider ones. Both genders perceived a 10 degree mesially angulated lateral incisor as more attractive.

Clinical and practical aspects of the gingival smile. A questionnaire-based survey.

Abstract Introduction: One of the main elements of facial esthetics is represented by the smile. A harmonious proportion between the elements of facial esthetics is an important subject of interest in dentistry. Aim of the study: This research aims to evaluate the impact of the gummy smile on future dental practitioners. Materials and Methods: A survey containing 16 questions was designed to find out the students’ perceptions about the ideal smile and if the gingival smile is considered youthful or unpleasing. The impact on their self-esteem, their willingness to change the gummy smile or not, the nonsurgical and surgical methods of treatment were also evaluated. Results: 212 answers were recorded and analyzed. Nearly three quarters (70.3%) of the respondents believe that having a gummy smile is unesthetic, while only 29.3% considered it to be a sign of youth. Self-esteem can be affected by having a gingival smile, but, according to the results, most of the students (45.8%) said that their daily lives have not been affected by it, 40.6% said that in a small amount, 10.4% said that their self-assurance has been very affected and only 3.3% admitted that the gummy smile distressed their confidence. When asked if they were willing to correct their gingival smile, 51.4% were open to improving it while 48.6% would not change it. Conclusions: Among dentistry students, excessive showing of the gums is believed to be unesthetic rather than a sign of youthfulness. The respondents are generally not affected in their daily life by having a gummy smile. Education regarding the methods of correcting it still needs to be addressed amongst future dental practitioners.

Knowledge and Attitude Toward Esthetic Dentistry and Smile Perception.

A smile is important in human communication and is increasingly valued in modern society. The perception of smile attractiveness is subjective and depends on many factors. This study aimed to evaluate and compare knowledge and attituderelated to esthetic dentistry in dental students versus dental interns, general dentists, and dental specialists, examine the self-perception of their smile, and identify parameters that influence smile perception. This cross-sectional study was conducted at King Abdulaziz University Dental Hospital in Jeddah, Saudi Arabia. Participants included dental students, interns, general practitioners, and specialists. They completed an electronic questionnaire covering demographics, knowledge about esthetic dentistry, attitudes towardsmile perception, and previous dental treatments. Data analysis involved descriptive statistics, bivariate analysis, and chi-square tests. A total of 275 individuals participated in our study. The study found that dental students' exposure and awareness of esthetic dentistry topics increased with academic progression. Gender, age, and marital status influenced self-perception and smile evaluation. More females perceived gender as an influencing factor in smile evaluation, while more males believed in the existence of an ideal smile. A substantial portion of the sample had undergone dental treatments, with no significant income-related disparities observed. This study highlights differences in knowledge and attitudes among dental students and professionals. Dental education appears to impact students' exposure to esthetic dentistry concepts. Moreover, gender, age, and marital status influence self-perception and evaluation of others' smiles.

The relationship between different levels of facial attractiveness and malocclusion perception: an eye tracking and survey study

IntroductionThe aim of this study was to investigate the relationship between levels of facial attractiveness and the perception of different types of malocclusion.MethodsA preliminary questionnaire was used to assign photographs of three female patients to low, moderate, and high facial attractiveness designations. Seven modified photographs for each smile photograph of each of these three patients were created. The evaluated photographs were as follows: P0: at rest position, P1: ideal smile, P2: − 2-mm (low) smile line, P3: + 4-mm gummy smile, P4: + 6-mm gummy smile, P5: maxillary anterior crowding, P6: median diastema, P7: polydiastema. An eye tracking device and a questionnaire were used to collect data from orthodontists, dentists, orthodontic patients, and laypeople.ResultsTotal fixation duration varied depending on the type of malocclusion, the level of facial attraction, and the participants’ occupations. In general, orthodontists and dentists had higher total fixation duration scores than orthodontic patients and laypersons. The maxillary anterior crowding photograph had the lowest visual analysis scale score at each attractiveness level (low, medium, and high). Visual analysis scale scores became similar at each attractiveness level only in the P4 photographs, and thus the difference in facial attractiveness disappeared.ConclusionWhile a worsening of the ideal smile had a smaller impact on aesthetic perceptions in an individual with low facial attractiveness, it had a significant negative impact on a person with high facial attractiveness. Anterior crowding and diastema had a more negative impact on facial attractiveness than low or high smile lines.

Influence of social media and corrected smile photographs in patients with malocclusion

The increased use of social networking sites, such as Instagram (Meta Platforms, Menlo Park, Calif), has been silently affecting facial satisfaction among patients. However, the potential of Instagram to motivate participants for orthodontic treatment when used with an adjunct, a photograph editing software, is yet to be assessed. From the initial 300 participants, 256 were included and randomly divided into an experimental group (participants were asked to provide their frontal smiling photograph) and a control group. The photographs received were corrected using photograph editing software and were shown along with other ideal smile photographs in an Instagram account to the experimental group, whereas the control group participants had access to only the ideal smile photographs. After browsing, the participants were given a modified version of the Malocclusion-Related Quality of Life Questionnaire. Questions assessing the general perception about one's smile, comparison with peers, desire to undergo orthodontic treatment, and the role of socioeconomic status showed a statistically significant difference (P<0.05) as most of the control group participants were unsatisfied with their teeth, had less desire to undergo orthodontic treatment and did not feel family's financial income to be a hurdle, contrary to the experimental group participants. A statistically significant difference (P<0.05) was also seen in assessing external acceptance, speech difficulties, and the influence of Instagram on orthodontic treatment, whereas the influence of photograph editing software did not show the same. The study concluded that the experimental group participants were motivated to undergo orthodontic treatment after viewing their corrected photograph.

A smile is a form of one's facial expression that is widely used and easy to see. Having an aesthetic and attractive smile can make a person more confident when interacting socially in their environment. There are eight main components that are assessed in a smile, two of which are the smile arc and gingiva display. Both have received a lot of attention because they are known to have a major influence on an aesthetic smile.The harmony of the smile arc and gingival display will produce an attractive smile. A consonant smile and a moderate smile line are considered the ideal smile arc and gingival display.

Pink Aesthetics: Gummy Smiles and Gingival Recession.

The ideal smile is one where there is harmony between the 'white' (tooth) and 'pink' (periodontal) aesthetics. The developments in the field of periodontology have enhanced aesthetic outcomes when managing excessive gingival exposure in a 'gummy' smile or excessive tooth exposure in gingival recession cases. This paper aims to outline the aetiology, classification, and management of both a 'gummy' smile and gingival recession, putting a spotlight on aesthetics.

VITAL ELEMENTS OF SMILE DESIGNING IN RESTORING DENTAL AESTHETICS

Smile is a component that draws interest of majority of dental specialties. It should be well understood what an ideal smile is and what are the factors that can affect it. Also, it should certainly be reected on the required successful treatment plan. It is the aim of this review to acquaint the reader to the various principles and the science behind designing a smile that is holistic and does not compromise the function.

Smile Preferences of Orthodontists and Patients from Frontal View about Gingival Display, Occlusal Cant and Smile ARC: A Study from Isra Dental College

Objective: Was to determine preferences of orthodontists and patients about gingival display, occlusal cant and smile arc. Material and methods: This descriptive cross sectional study was conducted on 65 participants (15 orthodontists and 50 patients). The inclusion criteria were participants who gave consent, Pakistani nationals, age from 20 to 45 years, and Layperson/patients. Exclusion criteria were mentally retarded, uncooperative, color blinded individual and dental students, dental attendants and technicians. Adobe photoshop CS6 was used to alter the smile arc, occlusal plane and gingival display incrementally. Student t test was run to compare the smile preferences between orthodontists and patients. P≤0.05 was considered significant. Results: The mean age of the participants was 33.15±6.29 years. Females (n=38, 58.5%) were more than males (n=27, 41.5%). For 0mm gingival show the score assigned by laypersons (6.86±0. 756) was statistically higher than orthodontists (6.40±0.507) (P=.031). Gingival show of 5mm was less acceptable to laypersons (1.92±0.752) than orthodontists (3.27±0.594) statistically (P&lt;0.001). Ideal smile arc was attractive for both laypersons (8.04±0.638) and orthodontists (9.33±0.724) but statistically more among orthodontists (P&lt;0.001). Significant difference was found between perception of orthodontists and laypersons for normal smile (P=.034) and canted smile (P&lt;0.001). Conclusion: Significant differences exist between opinions of orthodontists and laypersons in evaluating gingival display, smile arc and occlusal cant. Patient should be participated in treatment planning involving alteration of these smile parameters. Keywords: Smile perception, gingival show, smile arc, occlusal cant

The Perspective of Dental Aesthetics in Finding a Job as a Dentist: A Cross-Sectional Study

This study aimed to determine the influence of dental aesthetics in finding a job as a dentist and the employer’s willingness to interact in personal and professional setting. Ten dental students’ smiling photographs were taken prior to the correction of their dental aesthetic problems. The images were digitally altered to an ideal smile. Two different questionnaires were prepared (Groups A and B) with the images with or without alteration (ideal and non-ideal smile). The images with an ideal smile and non-ideal smile were randomly allocated in each group and assessed by 84 private dental practitioners who has the authority of hiring another dentist in their practice. Four questions were asked on the likelihood of being hired, friendliness, intelligence, and good clinical skills. In general, the students with ideal smile were more likely to be hired (p &lt; 0.05) except for those presented with buccally erupted canine and mild median diastema. Students with ideal smile scored higher in terms of friendliness and intelligence than the non-ideal smile. Most of them did not correlate a smile to an individual’s clinical skills and manual dexterity (p &gt; 0.05). In conclusion, individuals with an ideal smile was graded more friendly and intelligent thus increases the employer’s willingness to interact personally and is more likely to be hired in contrast to a person with a non-ideal smile. Therefore, an aesthetically pleasing smile is one of the factors affecting the chances of a dentist to be hired and improve their personal interaction with people.

Anatomical contribution of the orbicularis oculi to the zygomaticus major: An improved understanding of the smile with consideration for facial cosmetic procedures.

The aim of the present study was to determine the contribution of the orbicularis oculi (OOc) to the zygomaticus major (Zmj) in connecting the orbital region to the corner of the mouth. The OOc and Zmj of 22 embalmed adult Korean cadavers were dissected in 44 hemifaces. The OOc fibers were traced to determine their contribution to the Zmj. Parts of the superficial bundle in the orbital region of the OOc extended directly or indirectly to the Zmj in 22.7% of the specimens. The anatomical contribution of the OOc to the Zmj was divided into three categories depending on whether the connection between them was direct or indirect: (1) superficial orbital OOc fibers extended directly to the Zmj in 6.8% of the specimens, (2) superficial orbital OOc fibers extended to the zygomaticus minor and their small portion joined to the upper fibers of the Zmj in 15.9% of the specimens, and (3) no connection was identified between the OOc and Zmj in 77.3% of the specimens. The results of this study provide further anatomical insight into the relationship between the OOc and zygomaticus muscle complex. This information could be helpful for elucidating the anatomy of smiling and treatment and surgery designs for balanced or ideal smiles.

Development and validation of an occlusal cant index

BackgroundOcclusal cant (OC) is a malocclusion trait lacking indexing or classification that describes the extent and severity of tilt in the occlusal plane. The aims of this study were to develop an occlusal cant index (OCI) based on the degree of OC detection among orthodontists and laypeople and to validate the newly developed OCI by a panel of experts using content validity.MethodsThe ability to perceive OC was assessed in 134 participants (orthodontists = 67 and laypeople = 67). A frontal photograph of a model with an ideal smile with 0° of OC was obtained and manipulated to create various degrees of OC from 1–5° at the right and left sides. A set of 11 electronic photographs was displayed to the participants. The participants were asked to report whether they detected an OC in each photograph. The collected data was used as a baseline to develop an OCI. Then, a content validation of the OCI was performed using a questionnaire provided to a panel of experts comprising ten orthodontists.ResultsThe OCI was designed based on the threshold of OC detection. In both orthodontists and laypeople, the accuracy of OC detection increased as the amount of tilt increased. The threshold point of OC detection in orthodontists was at 2°, while in laypeople it was at 4°. There was a significant difference between orthodontists and laypeople in their ability to detect OC at 2–3° of tilt. The content validity index (CVI) showed excellent validity between the item-level CVI and the scale-level CVI of the OCI.ConclusionThe OCI was developed and implemented for diagnostic, communication, and research purposes. The index showed strong evidence supporting content validity.

ВЛИЯНИЕ ВОЗРАСТА И ЭСТЕТИЧЕСКИХ ПАРАМЕТРОВ УЛЫБКИ НА ЖИЗНЕННЫЕ АСПЕКТЫ ЧЕЛОВЕКА

Subject. A person's individuality depends on the peculiarities of his behavior in the conditions of modern life realities of society, his way of thinking and his communication skills. All the features of human behavior are interconnected, but some of them, in our opinion, play the most decisive role in life, in particular the appearance of a person. The dental status, namely, the ideal smile, is taken into account not only as a dentofacial composition, but also determines the special role of the aesthetic aspect of orthopedic rehabilitation, which is an integral part of the form of individual and collective life activity of a modern person. Thus, the study of aesthetic problems remains especially relevant dental care being provided to the dental patients.&#x0D; The aim is to study the relationship between the influence of age and aesthetic parameters of a smile on the sociability of patients.&#x0D; Methodology. Our study involved 30 male and female patients aged 30 to 40 years. We conducted the main (collecting anamnesis, study of diagnostic models) and additional (analysis of the results of the assessment of the dental aesthetic index (DAI)) research methods and questionnaires according to the V.F. Ryakhovsky test "Assessment of the level of sociability".&#x0D; The results of the study. Analysis of the results of the study allows us to conclude that 50% of patients from the examination group of the age category of 30-40 years have severe and very severe malocclusion, which directly affects the harmony of the smile. People smile less, they are embarrassed to speak, communication efficiency is not high, thus one of the conditions for building a successful career is not achieved. &#x0D; Conclusions. Having completed our research, we came to the conclusion that the age of the studied patients and the state of the dental system affect people's communication efficacy. Thus, dental health has a significant impact to the components of human well-being.

Smile esthetics perceptivity among dental practitioners and other professionals

To evaluate the perception of ten commandments of the smile esthetics among dental practioners and other professionals.The study population consisted of 540 samples (GroupI: 260 dental practitioners and Group II: 280 other professionals). A web based survey was conducted using google forms. Questionnaire was prepared including all the 10 variables determining smile esthetics using various smile photograph. Each questions has 4 options (A- ideal smile esthetics, B- mild deviation from ideal smile esthetics, C - moderate deviation and D- Marked deviation).The participants were asked to select the most attractive smile (the best options) for each of the ten variables that determines the smile esthetics. The rate the attractiveness of different smile variables were assessed by two group of the study population.Option A received the highest no: of responses for all the components of smile esthetics by both the dental and other professionals except the sixth and eighth smile component (gingival exposure and midline) where more responses received towards mild deviation from ideal by the other professional than the dental professional. There is no significant difference between the smile esthetic perception betwen the dental professionals and the other professionals. Orthodontist should pay more attention to improve smile esthetics in coordination with other dental speciality in addition to the correction of malocclusion

Influence on smile attractiveness of occlusal plane cant in conjunction with axially dental midline deviation

Today, smile esthetics are the primary concern of patients and orthodontists. Very limited studies have assessed the interactions between beauty variables. This study aimed to investigate the impact of the occlusal plane cant combined with midline axial deviation on smile attractiveness and determine the combined esthetic threshold of these two variables. The study was performed in a population in Zanjan, Iran. Frontal photos of a woman and a man with an ideal smile were downloaded from the Inte

Smile microesthetics as perceived by dental professionals and laypersons.

To evaluate and compare the perception of different dental professionals and laypersons toward altered gingival characteristics (microesthetics) and to identify those characteristics that are most negatively and positively rated. A smiling photograph of a female dental student was selected and digitally manipulated to create changes in different microesthetic parameters. These altered images were rated by the following five groups: 120 orthodontists, 45 periodontists, 49 prosthodontists, 130 general dentists, and 172 laypersons. Smile esthetics scores were calculated, and comparisons between groups were performed using the univariate general linear model. The presence of black triangles between the upper incisors was the most negatively rated, and the ideal smile was the most positively rated. Significant differences were detected in the rating scores among the different study groups (P < .05). Orthodontists, prosthodontists, and general dentists scored the presence of a black triangle in the smile as the least attractive, whereas periodontists and laypersons perceived the inflamed gingiva and pigmented gingiva as the least attractive, respectively. Dental specialists tended to give the altered smile images lower scores than the laypersons. The ideal smile and that with black triangles between the upper incisors were rated as the most and the least attractive smiles, respectively. Orthodontists, prosthodontists, and general dentists scored the presence of black triangles in the smile as the least attractive, whereas periodontists and laypersons perceived the inflamed gingiva and pigmented gingiva as the least attractive smiles, respectively. Dental specialists tended to give the altered smile images lower scores than the laypersons.
