Smile Aesthetics among Late Adolescents: Perspective of Adolescents, General Dentists and Orthodontists

Introduction: An adolescent’s personal experiences, peer influences and social environment can affect their preference towards smile aesthetics and have influence apart from the opinion of their orthodontists. Aim: To evaluate and compare the preferences regarding smile arc, gingival display, midline symmetry, shape and size of incisor teeth, buccal corridor space and smile index of adolescent subjects between late adolescents, general dentists and orthodontists. Materials and Methods: A total of 52 orthodontists, 111 general dentists and 275 adolescents (156 females, 119 males) had participated in this cross-sectional study from 1st September 2019 to 31st January 2020. Each participant was shown a photo album consisting of 5 sets of photographs of male and female adolescent subjects and was asked to rate them on 7 selected variables. The data obtained was subjected to comparison between the groups using Chi-square test. Results: While assessing smile of the female subject, other than the incisal edge position, the intergroup comparisons of gingival display (p=0.0001), midline symmetry (p=0.0001), shape of incisor teeth (p-value=0.0001), buccal corridor space (p=0.001), ratio of central: lateral incisor (p=0.016) and smile index (p=0.0001) were statistically significant. While assessing smile of the male subject, the intergroup comparisons of incisal edge position (p=0.0001), gingival display (p=0.001), midline symmetry (p=0.007), shape of incisor teeth (p-value=0.0001), buccal corridor space (p=0.0001), ratio of central: lateral incisor (p=0.0001) and smile index (p=0.0001) were statistically significant. Orthodontists’ accepted gingival display of 0-2 mm, midline deviation up to 2 mm and buccal corridor space of upto 5 mm and upto 25% increase in smile index in both genders. Conclusion: The Orthodontists and dentists have more similarities than differences in comparison to adolescents with respect to the smile preferences of adolescent subjects.

Bimaxillary transverse constriction in adults: Short-term follow-up of non-surgical arch expansion.

Concurrent maxillary and mandibular expansion is a treatment option for patients with maxillary and mandibular transverse constriction. These patients do not present with crossbite but require expansion due to narrow arches and associated crowding, dark buccal corridors and decreased anterior arch contour. The objective of the study is to first establish Bimaxillary Transverse Constriction as an under-recognized malocclusion and second to evaluate whether in adults the maxillary and mandibular arches can be successfully and safely expanded. Pre- and post-treatment study models and lateral cephalograms of 31 adults with Bimaxillary Transverse Constriction expanded non-surgically were analysed. Thirty adult orthodontic patients who did not require expansion served as a control. Expanders were turned no more frequently than every other day in the maxilla and every third day in the mandible. Measurements in both arches made on OrthoCAD models were transarch widths, molar and premolar axial angulation, clinical crown height of posterior teeth and cuspids, and mandibular divergence. Retrospective comparison of the 2 groups used independent Student's t tests for mean differences between groups. At pre-treatment, the expansion group demonstrated significant transverse constriction compared with the control. Increased widths were achieved in the expansion group (4mm in the maxilla and 2.5mm in the mandible), while the control group was unchanged. The mandibular plane was unchanged. There was no buccal attachment loss. Non-surgical expansion in the maxilla and mandible is a viable treatment option for adult patients with Bimaxillary Transverse Constriction.

Awareness of Dental Esthetic Standards Among Dental Students and Professionals.

PurposeThis study investigated the level of esthetic awareness of dental students and professionals.Material and methodsPhotographs depicting facial and smile features that deviate from universally accepted esthetic standards were presented in a questionnaire. Participants were asked to rate the images and to identify the main discrepant criteria. Eight hundred questionnaires were distributed to dental students, and clinicians. The data were analyzed using chi-square tests, Student’s t-test and one-way ANOVA with Tukey’s post hoc tests for multiple comparisons.ResultsStudents had 45.2% correct answers compared to 51.6% for clinicians. Among students, the highest awareness was found among 5th year students, followed by interns, 4th year and 3rd year students. The difference in the percentage of correct answers between clinicians and students overall was significantly higher for some criteria than for others, such as gingival esthetics, lip features, smile zone (incisal plane), facial features, and buccal corridor. Among clinicians, specialists responded correctly more often than did general practitioners in most of the investigated aspects.ConclusionThe ability of different group samples to diagnose discrepancies of smile esthetics was refined and enhanced with increased clinical experience and knowledge.

Comparison of smile esthetics among celebrities, dentists, and dental students in a Han Chinese population

Statement of problemVarious components of smile esthetics have been evaluated. However, whether these components affect smile esthetics in Han Chinese celebrities, dentists, and dental students is unknown. PurposeThe purpose of this study was to evaluate the smile esthetics of celebrities, dentists, and dental students in a Han Chinese population. Material and methodsFrontal images of smiles were obtained from the Internet for the celebrity group, while images of dentists and dental students were collected for the dentist and dental student groups. The buccal and posterior corridor ratios, the alignment discrepancy between the commissural and interpupillary lines, the number of teeth revealed, the width ratio relative to the golden proportion, and the width-to-length ratios of maxillary anterior teeth were calculated by using a photo-editing software program. Statistical analysis was performed by using 2-way ANOVA and the Tukey HSD test (α=.05). ResultsEligible images were obtained for 81 celebrities, 83 dentists, and 78 dental students. The celebrities were found to have the highest buccal and posterior corridor ratios and reveal the least teeth in the smile among the 3 groups (all P<.001). The alignment discrepancy for celebrities was significantly less than that for dental students (P=.025). Moreover, the absolute difference of width ratios from the golden proportion was significantly different from 0 for all groups (all P<.001). ConclusionsSignificant differences were found in the smiles of Han Chinese celebrities, dentists, and dental students in regard to the buccal and posterior corridor ratios, the alignment discrepancy between the commissural and interpupillary lines, and the number of teeth revealed. Chinese celebrities tended to have a smile that displays to the second premolar, with a medium buccal corridor width.

Evaluation of Smile Parameters in Nongrowing Subjects Using Photographs

Abstract Introduction An attractive or pleasing smile enhances the acceptance of an individual in the society by improving interpersonal relationships. In this new era of social media, people are more concerned about their smile; hence, smile esthetics has become the primary objective of orthodontic treatment. It is seen that various smile parameters change with age and gender. Aim The aim of the study was to evaluate various smile parameters in nongrowing patients using photographic analysis. Materials and Methods The sample comprised photographs of 50 subjects (8 males, 42 females) taken in natural head position and then divided into two age groups: Group I (25 subjects, aged 18–20 years) and Group II (25 subjects, aged 23–29 years). The various parameters were analyzed using Adobe Photoshop software (version CS 6; Adobe System Inc., California, United States): upper lip and lower lip lengths during rest and smiling, smile index, buccal corridor, upper and lower lip thickness, interlabial gap, incisal display, widest visible maxillary display, and intercommissural width. Results The results showed that lower lip length at rest and smiling, interlabial gap, incisal display, inner commissure width, and widest visible maxillary display were increased, whereas upper lip length both at rest and smiling, upper and lower lip thickness, outer commissure width, smile index, and buccal corridor were decreased with age. Statistically significant sex-related differences were found in upper lip length at rest and lower lip length both at rest and smiling. Conclusion Orthodontic treatment must incorporate various esthetic elements of smile to achieve desirable results.

Clinical effectiveness of orthodontic treatment on smile esthetics: a systematic review.

Objectives: The aim of this systematic review is to identify how different types of orthodontic interventions affect the esthetics of the smile, any time after orthodontic treatment.Materials and methods: A systematic search of the literature was carried out using 5 electronic databases (PubMed, Embase, The Cochrane Library, Scopus, Dentistry and Oral Sciences Source) that included articles until October 2017. Randomized and non-randomized controlled clinical trials, case–control observational studies, and cohort and cross-sectional studies with validated data collection and/or follow-up periods reporting on orthodontic interventions that changed the smile any time after orthodontic treatment were part of the study protocol. Only studies that were published in the English language and those that had human patients of any age and gender who underwent orthodontic treatment were included.Results: A total of 814 articles were found and 9 of them were included (7 cohort and 2 cross-sectional studies). Among the selected articles, 8 stated the type of orthodontic intervention used during treatment and 1 did not specify the intervention. Eight articles were judged of moderate risk and 1 had high risk of bias.Conclusion: Orthodontic treatment affects the esthetics of the smile in three dimensions. There was slight evidence that extractions do not affect the smile width and buccal corridors area. Evidence on palatal expansion was controversial. The remaining existing data evidence that investigated smile esthetics after orthodontic treatment was uncertain. Therefore, more validated, evidence-based studies are needed.

Changes in smile morphometric indices following maxillary advancement and mandibular setback surgery in skeletal Class III patients

Objectives: The aim of this study was to evaluate the changes in smile morphometric indices following maxillary advancement and mandibular setback surgery in patients with skeletal class III malocclusion.&#x0D; Materials and Methods: Smile morphometric indices were measured on frontal rest and smile photographs of 15 female patients with skeletal Class III malocclusions before and three months after maxillary advancement and mandibular setback surgery. Pre- and post-surgery measurements were compared.&#x0D; Results: The amount of left and right commissural height, philtrum height, and maximum upper incisor show at rest did not change significantly three months after surgery (p&gt;0.05). The amount of maximum upper and lower incisor show, interlabial gap, smile width and index, buccal corridor ratio, gingival display, and smile arc on the frontal smile photographs didn’t showstatistically significant difference before and after surgery (P&gt;0.05).&#x0D; Conclusion: Orthognathic surgery in patients with skeletal Class III malocclusion had no significant effect on rest and smile parameters from the frontal view.&#x0D; Bangladesh Journal of Medical Science Vol.18(2) 2019 p.216-221

Perception of smile attractiveness among orthodontists, restorative dentists, and laypersons in Saudi Arabia.

Background:A smile is defined as a universal welcome. The perception of smile attractiveness is affected by the persons' social background and their own experiences. The existing literature states that orthodontists, restorative dentists, and laypersons have different opinions.Aims:The aim of this study is to compare the perception of orthodontists, restorative dentists, and laypersons regarding smile esthetics.Materials and Methods:A survey-based study was conducted. The target population was orthodontists, restorative dentists, and laypersons in Saudi Arabia. An electronic survey that included digitally altered photographs representing different smile parameters was designed by an Adobe Photoshop Certified Expert. Participants were asked to choose the most attractive smile in each question.Results:Unilateral changes in the width or length of the central incisors were the least attractive among the three groups. About 38%, 48%, and 41% of the participating orthodontics, restorative dentists, and laypersons, respectively, found that wider buccal corridors were more attractive. Moreover, 27% of the laypersons found the reversed smile arc to be attractive.Conclusion:The tolerance level in evaluating the asymmetry and the width of the buccal corridors was similar for the three groups. Laypersons were less sensitive to the deviations from the ideal in the smile arc and the amount of lower lip coverage of the incisors.Clinical Significance:Understanding the differences in the perception of smile attractiveness among orthodontists, restorative dentists and laypersons will undoubtedly be beneficial in diagnosis, setting treatment objectives and treatment planning.

Perception of Buccal Corridor Space on Smile Aesthetics among Specialty Dentist and Layperson.

Objectives:The aim of this study was to assess and compare the perception of smiles with and without buccal corridor spaces (BCSs) among prosthodontists, orthodontists and laypersons on smile aesthetics.Materials and Methods:Smiling photographs of subjects with wide BCSs were collected and digitally manipulated to eliminate the BCSs. Digitally altered and unaltered photographs were placed together and assessed for aesthetic appeal using visual analog scale of one to ten by prosthodontists, orthodontists, and laypersons. One-way analysis of variance (ANOVA) and two-way ANOVA were applied to evaluate the collected data using the Statistical Package for the Social Sciences (SPSS 22), Epi Info 6.0, and GraphPad Prism, version 6.0.Results:The total mean value scores of smiles with BCSs were significantly higher than those of smiles without BCSs (P < 0.001). Orthodontists and prosthodontists significantly appreciated BCSs and graded the smiles with BCSs to be much more attractive (P > 0.005). Laypersons rated the smiles with BCSs with greater mean values, but the difference in mean values of smiles with and without BCSs was not significant (P < 0.005). No significant difference was found between the perceptions of prosthodontists and orthodontists.Conclusion:The results of this study reveal that the smiles with BCSs were notably more desirable than the smiles without BCSs. Laypersons, orthodontists, and prosthodontists evaluated smiles differently. The smiles with BCSs were appraised much more pleasing by prosthodontists and orthodontists. Laypersons could not significantly appreciate BCSs, but rated smiles with BCSs as more acceptable.

Perception of general dentists and laypersons towards altered smile aesthetics.

OBJECTIVES:This study aimed to evaluate how dental practitioners and laypersons differ in their perception of altered smile aesthetics based on viewing images of a digitally manipulated smile.MATERIALS AND METHODS:A photograph with close to ideal smile characteristics was selected and digitally manipulated to create changes in buccal corridor space (BCS), midline diastema, gingival display, and midline shift. These altered images were rated by two groups: dental practitioners and lay persons using a visual analogue scale. The mean ± standard deviation (SD) of both groups were calculated and the Student's t-test was used to identify any statistically significant differences between the groups. Data analysis was done using the Statistical Package for Social Science (version 23.0; SPSS Inc., Chicago, Illinois, USA).RESULTS:The dentists were more sensitive to changes in the midline shift than laypeople and provided lower scores. There were no significant differences between the two groups when the gingival display alteration was ≤3 mm. However, for gingival display of 4 mm and 5 mm, there was significant difference between the two groups, with dentist rating them poorer as compared with the laypeople (P < 0.001). Dentists were more sensitive than the laypeople for midline diastema of 2 mm and 3 mm (P < 0.001 and P = 0.005 respectively). Changes in the BCS had minimal impact on the overall esthetic score for both the groups.CONCLUSIONS:Perception of smile esthetics differed between dentists and laypersons.

Women’s facial attractiveness nowadays – results from analysis of public figures

Aim. To identify the main facial features associated to facial attractiveness in women nowadays. Method. A descriptive study was conducted on a sample of 20 female public figures, very famous and successful women, most frequently actresses, singers or models, considered very beautiful nowadays. Their selection followed the analysis of several recent tops that aimed identifying most beautiful women, in which raters were lay persons. Data was collected by analyzing photos from frontal and lateral view, during rest position and smiling. Results. The persons analyzed registered diverse facial traits. Most obvious trends, encountered in more than 75% of them, included: Caucasian race; straight and long hair; average nasal tip protrusion; maxillary dental midline concordant to facial midline; a thicker lower lip compared to the upper lip; exposure of only maxillary incisors during smile; decreased or absent buccal corridor; maxillary central incisors of oval/rectangular shape; absence of maxillary teeth crowding. Other frequently encountered features were: American nationality; brown hair; eyes with medium size, almond shape, wide set, of green color; nose with an average width; face with a decreased lower third and a slightly convex profile; a thick lower lip and an average upper lip; exposure during smiling till the first molar, with a normal smile line. Conclusions. The public beautiful women nowadays register features that are generally associated to an increased facial attractiveness. Knowledge of trends in facial beauty is useful in dental practice, in order to understand better patient’s need in terms of esthetic expectations.

Comparison of the influence of dental and facial aesthetics in determining overall attractiveness

Orthodontic treatment aims at improving the perceived aesthetics; hence knowing which characteristics play a significant role in determining aesthetics is an important orthodontic objective. The aim of this study was to evaluate among laypersons, general dentists and orthodontists the importance of dental versus facial aesthetics. Frontal face smile photographs of eight volunteers (4 males & 4 females), age group ranging from 16 to 24 years were used for the study. One hundred and fifty evaluators (50-lay people, 50 general dentists and 50 orthodontists) were asked to select which face they found most attractive-an aesthetically pleasing face with a malocclusion evident in their smile or an average face with an aesthetic smile. A questionnaire method was followed. There was a statistical significant difference in the perception of the faces among the group of the evaluators. Crowding and midline diastema have more of an effect on the perception of attractiveness by laypersons than gumminess or increased buccal corridor space. Facial attractiveness is the dominating factor compared to dental aesthetics in cases where the malocclusion is less noticeable.

Facial Esthetic Parameters: A Descriptive Analysis of Facial Class and Smile in Young Subjects

Facial esthetics have an important function in psycho-social relations and is a response to anatomical and muscular dynamics; differences in facial skull position can modify a subject ́s facial esthetic and smile. The aim of this research is to know smile esthetics and the presence of facial modifications. We studied standardized photographs of patients between 18 and 37 years old and determined soft tissue relation to identify the facial class in lateral images defined as class I, II or III; we analyzed their relation to dental/ gingival presentation in reference to a high, normal or low smile. The data was analyzed in a descriptive technique. The results show that the low smile has a minor percentage and a normal smile was present in 47.62% of class I subjects, 34.29% of class II subjects and 75% of class III patients; high smile was present in 54.29% of the class II subjects; the buccal corridors, as an esthetic element follows the normal parameters in a low percentage and the greater or lesser size of the buccal corridors was observed in 71.43% of class I subjects, 74.29% of class II subjects and 75% of the class III subjects. It was concluded that mayor variations exist in the smile of subjects with different facial class and that the buccal corridors was excessive in the majority of subjects, thereby demonstrating the importance of analyzing this concept of esthetics in our population.

Smile attractiveness perception regarding buccal corridor size among different facial types.

The width of the buccal corridor (BC) is one of the factors affecting smile attractiveness. The aim of this study was to determine the effects of the BC size on the smile attractiveness of individuals with short, normal and long faces from the viewpoint of laypersons, general dentists and orthodontists. Smiling photographs of male and female subjects who met the inclusion criteria were digitally altered to create 3 BC sizes (narrow: 2%; normal: 15%; wide: 28%) and 3 facial types defined by the facial index (FI) (short face: FI ≤ 83.9; normal face: 84.0 ≤ FI ≤ 87.9; long face: FI ≥ 88.0). Nine different combinations were made and the evaluators rated the overall attractiveness and acceptability of each smile on a 10-millimeter visual analog scale (VAS). A total of 53 raters (22 laypersons, 16 general dentists and 15 orthodontists) participated in this study. The orthodontists and general dentists had similar viewpoints and they preferred narrow and normal BCs over the wide ones in all facial types. Laypersons preferred normal BC for normal faces, while they did not distinguish different BCs in short faces. Variations in the BC size affect smile attractiveness in different facial types and wide BCs are attributed to the least attractive smiles. Due to the different viewpoints of laypersons and professionals in this regard, there is no justification for expanding the maxillary arch to achieve more attractive smiles.

Perception of facial, dental, and smile esthetics by dental students.

To comprehensively assess dental students' perception of facial, dental and smile esthetics and to assess whether such a perception varies by gender, clinical training, and Grade Point Average (GPA). Series of photographs were digitally manipulated involving three facial, two smile, four dental, and one gingival components. Students in preclinical and clinical levels evaluated the original and manipulated images using a visual analogue scale scored from 1 to 5 where 5 is the standard image and 1 is the least pleasant one. The responses were then analyzed using Mann-Whitney test. A P value of < .05 was considered significant. Four hundred and eight dental students participated in this study. With regard to the overall esthetics, males and clinical students scored higher than females and preclinical students, respectively, did. With regard to the individual esthetic components, males had significantly higher scores in buccal corridors, midline shift, clinical crown width, and gingival marginal height, while females had significantly higher score in median diastema (P < .05). Clinical students had a better perception of facial asymmetry, gingival display, buccal corridors, and clinical crown width compared to the preclinical students. Effect of GPA was minimal and even contradictory; students with lower GPA had a better perception of midline deviation and occlusal canting than those with higher GPA scores. Male dental students, and unexpectedly unlike females, have a better perception of facial and dental esthetics. Unlike GPA, whose effect was minimal, clinical training has a substantial positive effect on the assessment of beauty. Appropriate perception of facial, dental and smile esthetics by dental students is of paramount importance for providing adequate dental services and for improving and polishing their professionalism.© 2018 Wiley Periodicals, Inc.

Comparing Orthodontist, Prosthodontist, Dental and Non-Dental Student Views on the Impact of Buccal Corridor on Smile Attractiveness of Women with Different Face Shapes

Objectives Today, creating a balanced and attractive smile is the main goal of treatment in modern orthodontics. The buccal corridor is one of the controversial aspects of the smile attractiveness. The aim of this study was to compare the impact of buccal corridor on smile attractiveness of women with Mesoprosopic, Leptoprosopic, and Euryprosopic face types, from the perspective of orthodontists, prosthodontists, Dental and non-dental students.Methods In this comparative cross-sectional study, Photos were taken from 3 women with different face types and by making some changes in these photos, 5 buccal corridors (2%, 10%, 15%, 22%and 28%) were created for each one. Eventually, in order to survey, each 15 pictures were provided to individuals in the study group. Statistical analysis was performed by SPSS21 software, using K-S (Kolmogorov-Smirnov), Kruskal Wallis and Mann Whitney tests.p-value<0.05 was considered significant.Results Orthodontist and non-dental students considered that nearly wide smile for leptoprosopic face shape and wide smile with the minimum buccal corridor for variety of mesoprosopic and euryprosopic face shapes have the most attractiveness (p<0.05). Prosthodontists considered wide and narrow smiles as the least attractive regarding all types of faces (p<0.05).Conclusion Face shapes did not have a significant impact on the selection of the most attractive smile by prosthodontists, while orthodontists and non-dental students shared a similar view on the selection of the most attractive smile regarding the face shape.

Evaluation of different smile parameters in the Turkish population

Aim: In the past, patients and dentists thought that the dental aesthetics could only be ensured with modifications on teeth. Together with the latest developments in the smile analysis and aesthetic design, researchers have identified the aesthetics based on facial, oral-facial, dentogingival, and dental components. The aim of this study is to evaluate the smile type (ST), smile line (SL), maxillary incisal line types (ML), and buccal corridor widths (BC) related to the smile aesthetics. Methodology: A total of 190 individuals (92 males and 98 females) aged between 18 and 25 years, living in different cities of Turkey and studying at Atatürk University, Faculty of Dentistry were included in the study. In the study, the smile types, smile lines, maxillary incisal curvatures and buccal corridor widths of the individuals were examined. Results: In the young Turkish population, the most common ST in both genders is the commissural smile, and the least common ST is the complex smile. The most common SL is the SL, and the least common SL is the high SL, and it varies by gender. While the most common ML is the convex line in both genders, the least common ML is the reverse incisal line. While the last visible maxillary tooth during the social smile is mostly the maxillary 2nd premolar tooth, it is the maxillary 2nd molar tooth at least. Conclusion: The incidence of some smile parameters in young Turkish population varies according to gender.

Smile attractiveness related to buccal corridor space in 3 different facial types: A perception of 3 ethnic groups of Malaysians

Statement of problemBuccal corridor space and its variations greatly influence smile attractiveness. Facial types are different for different ethnic populations, and so is smile attractiveness. The subjective perception of smile attractiveness of different populations may vary in regard to different buccal corridor spaces and facial patterns. PurposeThe purpose of this study was to determine esthetic perceptions of the Malaysian population regarding the width of buccal corridor spaces and their effect on smile esthetics in individuals with short, normal, and long faces. Material and methodsThe image of a smiling individual with a mesofacial face was modified to create 2 different facial types (brachyfacial and dolicofacial). Each face form was further modified into 5 different buccal corridors (2%, 10%, 15%, 22%, and 28%). The images were submitted to 3 different ethnic groups of evaluators (Chinese, Malay, Indian; 100 each), ranging between 17 and 21 years of age. A visual analog scale (50 mm in length) was used for assessment. The scores given to each image were compared with the Kruskal-Wallis test, and pairwise comparison was performed using the Mann-Whitney U test (α=.05). ResultsAll 3 groups of evaluators could distinguish gradations of dark spaces in the buccal corridor at 2%, 10%, and 28%. Statistically significant differences were observed among 3 groups of evaluators in esthetic perception when pairwise comparisons were performed. A 15% buccal corridor was found to score esthetically equally within 3 face types by all 3 groups of evaluators. The Indian population was more critical in evaluation than the Chinese or Malay populations. In a pairwise comparison, more significant differences were found between long and short faces and the normal face; the normal face was compared with long and short faces separately. ConclusionsThe width of the buccal corridor space influences smile attractiveness in different facial types. A medium buccal corridor (15%) is the esthetic characteristic preferred by all groups of evaluators in short, normal, and long face types.

Comparison of esthetic smile perceptions among male and female Indonesian dental students relating to the buccal corridors of a smile

Background: A smile constitutes a form of measurement as to whether or not an orthodontic treatment has proved successful. A smile is said to be ideal if a balance exists between the shape of the face and teeth. One benchmark used to assess the quality of an ideal smile is that of buccal corridors. These are formed of the black space between the lateral edge of maxillary posterior teeth and the corner of the lip which appears during the action of smiling. Evaluating the contrasting perceptions of male and female smiles based on buccal corridor aspects is considered important to identifying the specific qualities an ideal smile. Purpose: The purpose of this study was to determine the difference between the perceptions of an ideal smile held by Indonesian dental students of both genders based on buccal corridors. Methods: A total of 36 dental students, equally divided between male and female students and ranging in age from 18-21 years old, were enrolled in this study. The smiles of all subjects were photographed from the front for later assessment by the subjects themselves. Assessment was undertaken twice, with a two-week interval between the first and second, by comparing subjects’ photographs with reference pictures of buccal corridors. Data gathered were analyzed by using kappa-statistic and U-Mann Whitney. Results: The results indicated that all the subjects showed a good level of coincidence in their analysis (κ=0.76). Statistical analysis showed that the score of 0.123 (p&gt;0.05) was shown in U-Mann Whitney. Conclusion: Indonesian male and female dental students have the same perception of an aesthetic smile with regard to its buccal corridor.
