RESUMO
BACKGROUND: A person's smile has been identified as one of the first observed facial characteristics. Even minor deviations from societal beauty standards, especially among younger individuals, can have a negative effect on their self-esteem. The aim of this research is to evaluate the self-perceived psychosocial impact of dental aesthetics and self-esteem among respondents and their association, as well as to determine the main factors contributing to dissatisfaction with dental appearance. METHODS: This research was conducted as a cross-sectional study that surveyed students of the University of Novi Sad. Other Universities and private faculties were excluded from participation. Data collection used standardized questionnaires measuring the Psychosocial Impact of Dental Aesthetics (PIDAQ) and the Rosenberg Self-Esteem Scale (RSES). Questionnaire (an online GoogleForms) was sent to the students via official Facebook groups of the faculties, student's e-mails and Instagram profiles. Data analysis included descriptive statistics, Students T-test, ANOVA, multiple linear regression analysis and Spearman coefficient. To test internal consistency, Cronbach's alpha(α) was calculated for the questionnaire as a whole (0,761) and each used questionnaire (PIDAQ - 0.766; RSES - 0.765). Cronbach's alpha(α) was also calculated for each domain from PIDAQ (DSC-0.946; SI-0.882; PI-0.953; AC-0.916). RESULTS: The study involved 410 participants, predominantly female (80%), aged between 21 and 23 (45.4%), primarily in ther first academic year (21.5%), and with a grade point average between 8.01 and 9.00 (42.4%). Data analysis has shown a statistically significant difference in the total PIDAQ score and SI subdomain in relation to the academic year (total PIDAQ p = 0.025; SI p = 0.000). In terms of self-esteem, results of multiple linear regression analysis showed that the academic year (95%CI: 0.410-1.837; p = 0.002) and the average point grade (95%CI: -0.025-1.600; p = 0.047) were significant predictors of greater self-esteem. The Spearman coefficient value (r=-0.316, p < 0.001) confirmed a statistically significant negative correlation between PIDAQ and self-esteem. Only 34% of respondents expressed satisfaction with their teeth. Dissatisfaction about the smile was primarily attributed to the arrangement and positioning of their teeth (32.2%). Financial constraints were identified as the main barrier for seeking interventions to improve smile satisfaction (39.5%). CONCLUSION: Students experiencing a greater psychosocial impact of dental aesthetics tended to exhibit lower self-esteem.

OBJECTIVE: To evaluate the prevalence of bullying among schoolchildren and to study the correlation between bullying and a specific type of malocclusion, self-esteem, oral health-related quality of life (OHRQoL), the need for orthodontic treatment and socioeconomic status. DESIGN: A cross-sectional study. SETTING: Low, middle and high socioeconomic-class schools in the same educational district in Cairo, Egypt. PARTICIPANTS: A total of 324 Egyptian schoolchildren aged 11-14 years. METHODS: Validated questionnaires were used to assess self-reported bullying frequency and intensity, self-esteem and OHRQoL. The Index of Orthodontic Treatment Need (IOTN) was used to assess the orthodontic treatment need and the participants' occlusion was classified according to the British Standard Incisors (BSI) classification. RESULTS: Bullying was found to be prevalent in 61.7% of the sample. Regression analysis revealed that participants with a Class II division 1 incisor relationship had the highest odds ratio (OR) for predicting bullying (OR = 1.86, 95% confidence interval [CI] = 1.38-2.15). Being bullied was significantly associated with lower self-esteem (OR = 0.47, 95% CI = 0.13-0.78), worse OHRQoL (OR = 2.73, 95% CI = 1.95-3.15) and a high need for orthodontic treatment, as determined by the IOTN Dental Health Component score (OR = 1.33, 95% CI = 1.05-1.95) and IOTN Aesthetic Component score (OR = 1.52, 95% CI = 1.12-1.88). Moreover, participants in high and middle socioeconomic-class groups had a lower OR for predicting bullying than those in the low socioeconomic-class group (OR = 0.27, 95% CI = 0.13-0.54). CONCLUSION: The bullying prevalence among Egyptian schoolchildren aged 11-14 years was very high. The prevalence of bullying was higher in schoolchildren with higher orthodontic treatment need and Class II division 1 incisor relationship. Bullying was correlated to poor self-esteem as well as poor OHRQoL. In addition, low socioeconomic status was found to be a potential predictor for bullying.
RESUMO
OBJECTIVE: This study aimed to evaluate the relationship between aesthetic concern and self-esteem in adolescents with severe malocclusion. METHODS: A cross-sectional study developed with 543 adolescents from 11 to 13 years of age and severe malocclusion was selected. Dental aesthetic index (DAI) diagnosed the malocclusion and selected the groups with greater severity (DAI 3 and 4). Aesthetic concern was assessed using the oral aesthetic subjective impact scale (OASIS) and considered an outcome variable. The global negative self-evaluation (GSE) evaluated self-esteem. The variables were analysed using Poisson multiple regression and the model adjustment determined by the Akaike information criterion (AICC). The effect of each variable on OASIS was expressed as a prevalence ratio (PR) with 95% confidence intervals. The analyses were performed using the R program with a significance level of 5%. RESULTS: A significant association was observed between aesthetic concern scores and self-esteem (p<.05). Individuals with low self-esteem had OASIS scores 14% higher (PR: 1.14; 95% CI: 1.08-1.21). There was no significant association between OASIS and gender and age (p>.05). CONCLUSIONS: Self-esteem modulates how the individual perceives malocclusion. Adolescents with severe and very malocclusion and low self-esteem have greater aesthetic concerns.

OBJECTIVES: This study compared two surgical techniques using acellular dermal matrix (ADM) for the treatment of multiple gingival recessions. MATERIAL AND METHODS: Twenty patients, with bilateral RT1 gingival recessions, were selected. One side received a modified extended coronally advanced flap (MECAF), and the contralateral side a supra-periosteal flap (TUN). The evaluated parameters were probing depth (PD), relative clinical attachment level, gingival index, gingival recession height (GR), width of keratinized tissue, keratinized tissue thickness, and gingival recession area at baseline and 6 months postoperative. Pain was evaluated weekly, using a visual analog scale (VAS) during first month postoperative. RESULTS: Both groups were effective in reducing GR (ΔGR: MECAF 2.28 mm; TUN 1.93 mm), without significant differences. The % of root coverage was numerically superior favoring MECAF (MECAF 61.24%; TUN 56.07%), without significant differences between groups. VAS scale failed to provide differences between groups. CONCLUSIONS: Both treatment were effective in root coverage and might be valuable for the treatment of multiple gingival recessions. The use of vertical releasing incisions and a flap design including the papillae did not hamper root coverage. CLINICAL RELEVANCE: This study compared two techniques for use of ADM in large multiple gingival recessions. Within its limitations, both treatments successfully achieved root coverage and were able to reduce gingival recession. It is expected a partial root coverage when using these techniques in large gingival recessions. The study failed to provide significant differences between groups. The use of modified extended coronally advanced flap may be advisable for the treatment of multiple gingival recessions, specially involving large defects when using ADM, to avoid early matrix exposure.

OBJECTIVE: (i) To study the measurement invariance of Orofacial Esthetic Scale (OES) and Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ), (ii) to compare the perception of orofacial appearance (OA) and (iii) to study the frequency of individuals who have sought or received aesthetic dental treatment between Brazil and Finland. METHODS: This was a cross-sectional observational study with snowball non-probability sample selection. Students and staff from universities in Finland and Brazil were invited to participate. Data were collected online using a demographic questionnaire, OES and PIDAQ. The samples consisted of 3636 Finns (75.0% female; age: 32.0 years) and 1468 Brazilians (72.6% female; age: 33.2 years). The frequency of receiving aesthetic dental treatment was estimated. If configurational invariance was observed, cross-national measurement invariance was verified by multigroup analysis. When measurement invariance was attested, factor scores were compared using Welch's t-test. RESULTS: OES showed configurational and measurement invariance and no significant difference between the countries. Despite similarity in satisfaction with OA, 71.9% of Brazilians had received aesthetic dental treatment, while 59.4% of Finns had never sought such treatments. PIDAQ did not present configurational invariance between the countries. CONCLUSION: Although there is no difference in satisfaction with OA, seeking and receiving aesthetic dental treatment is significantly greater for Brazilians. Psychosocial impact of OA is perceived differently in the studied countries.

OBJECTIVE: To develop the Finnish version of the Orofacial Esthetic Scale (OES-Fi) and the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ-Fi) and estimate the psychometric properties of these instruments applied to adult Finns. METHODS: The English versions of the instruments were translated into Finnish and back-translated. Thereafter, OES-Fi and PIDAQ-Fi were established in a pilot study. The factorial validity was estimated using Confirmatory Factor Analysis (CFI, TLI, SRMR) in independent samples (Test and Validation samples). The measurement invariance of the factorial models was tested using multigroup analysis (ΔCFI). Convergent validity [Average Variance Extracted (AVE)] and reliability [Composite Reliability (CR) and α] were estimated. RESULTS: A total of 3636 individuals [mean age = 32.0 (SD = 11.6) years, 75% women] participated in the study. After refinements, the factorial model of the instruments showed an adequate fit to the data (CFI ≥0.94, TLI ≥0.90, SRMR ≤0.07) and showed measurement invariance in two independent samples (|ΔCFI| <0.01). Convergent validity (AVE = 0.54-0.82) and reliability (α = 0.86-0.94) were adequate. CONCLUSION: The data obtained using OES-Fi and PIDAQ-Fi were valid and reliable. Thus, these instruments could be useful for evaluating individual satisfaction with orofacial appearance and the psychosocial impact of dental aesthetics in a clinical or research setting.

BACKGROUND: Based on previous theoretical oral-health-related quality of life (OHRQoL) models and most recently framework, as well as sociocultural model of body image dissatisfaction, the current study aimed to investigate the effect of individual (dental aesthetics and dental appearance social comparison) and sociocultural factors (social reinforcement from parents, peers and mass media on dental aesthetics) as well as their interaction on psychosocial dimension of OHRQoL among adolescent orthodontic patients. METHODS: In this cross-sectional study comprising 427 adolescent orthodontic patients (151 boys and 276 girls) aged between 11 and 16 years old, the psychosocial dimension of OHRQoL was measured by Psychosocial Impact of Dental Aesthetics Questionnaire. Individual predictor of dental aesthetics was defined by the Aesthetic Component of the Index of Orthodontic Treatment Need, and dental appearance social comparison was assessed by four items adapted from Physical Appearance Comparison Scale. Sociocultural predictor of social reinforcement was measured by six items adapted from Perceived Sociocultural Pressure Scale. Spearman correlations, path analyses, and structural equation modeling were used to build up several predictive models. RESULTS: As hypothesized, two direct pathways were observed that patients' dental aesthetics and all three sources of social reinforcement directly predicted the psychosocial dimension of OHRQoL. Meanwhile, we observed one indirect pathway, that three sources of social reinforcement predicted the psychosocial dimension of OHRQoL, in part, through dental appearance social comparison. CONCLUSIONS: This study provides preliminary evidence indicating that dental aesthetics, social reinforcement and dental appearance comparison are reliable predictors of psychosocial dimension of OHRQoL among adolescent orthodontic patients.

BACKGROUND: A number of reference patterns such as the interincisal line, curve of the upper lip, width of the smile or shape of the teeth have been studied in different populations. Determining the frequency of different smile aesthetic parameters in a European Caucasian population and exploring possible gender differences is important in order to obtain predictable treatment outcomes. METHODS: Photographs were obtained under resting and forced smiling conditions in 140 individuals (70 males and 70 females) with a mean age of 20.1 ± 4.3 years. Different variables were recorded, including the position of the maxillary interincisal midline in relation to the facial midline, the arc and width of the smile, and the shape of the teeth. The data were processed using the SPSS version 15.0 statistical package, with application of the chi-squared test and a confidence level of 95%. The statistical power was 80%, and the level of significance 5% (α = 0.05). RESULTS: A total of 94.3% of the sample presented a maxillary interincisal midline coinciding with the facial midline, and 80% had a consonant smile line. The curve of the upper lip was upwards in 47.1% of the cases, followed by a straight curve in 41.4%. Most of the subjects (84.3%) presented a medium smile line with tooth exposure to the second premolar (61.4%). There were no significant differences between males and females. CONCLUSIONS: The integration of aesthetic criteria is needed in order to guarantee satisfactory and predictable dental treatment outcomes. There were no statistically significant differences between males and females. The maxillary interincisal midline coincided with the facial midline, with a consonant smile arc and a medium smile line, upward lip curve and oval tooth shape.

OBJECTIVE: To determine the effects of dental aesthetics and socio-demographics on psychosocial well-being among students of health sciences. Methods: The analytical cross-sectional study was conducted at a private tertiary care health centre in Karachi from March to August 2018, and comprised medical, dental and pharmacy students. Data was collected using a structured adapted questionnaire comprising Psychosocial Impact of Dental Aesthetics Questionnaire and Aesthetic Component of Index of Orthodontic Treatment Need which was graded from group 1 to group 5. Data was analysed using SPSS 22. RESULTS: Of the 385 subjects, 122(31.7%) were males and 263(68.3%) were females. The overall mean age was 20.6±1.70 years. There were 177(46%) medial students, 125(32.5%) dental and 83(21.6%) pharmacy undergraduates. Dental aesthetics concern and social impact factors were significantly different between the genders (p<0.05). The two factors were also significantly different with respect to years of study (p<0.05). Significant difference was observed between aesthetic concern and age (p<0.05). Dental self-confidence the highest in group 1 with a mean of 2.6±1.02, and the lowest in group 5 with a mean of 2.0±1.16 of Aesthetic Component of Index of Orthodontic Treatment Need. CONCLUSIONS: The psycho-social life was affected by poor dental aesthetics, indicating that dental therapy and cosmetic treatments had an influence over psychological well-being of individuals.

OBJECTIVE: The purpose of the present study was to assess dentin shear bond strength (SBS) and mode of bond failure of bioactive cement (BA) in comparison to conventional resin cement when photosensitized by Er,Cr: YSGG Laser (ECL). METHODS: The present in-vitro study was carried out from March 2019 to May 2019. Sixty permanent non-carious, intact, non-fractured molars were isolated and mounted vertically in acrylic resin. Buccal surface of each molar tooth was ground, polished and surface treated with ECL. Ketac conditioner was applied on the surface washed and air dried surface. Tetric -N-Bond adhesive was applied on forty-five samples and light cured. The specimens were allocated into four groups (n=15) according to the type of cement used i.e., Calibra (C), BA, Variolink II (V) and Maxcem-Elite (ME). For SBS testing was performed using the universal testing machine. Eight samples from each group were assessed for modes of failure. Means and standard deviations were compared using analysis of variance (ANOVA) and Tukey's post hoc test at a significance level of p < 0.05. RESULTS: The highest mean SBS was observed in group ECL-C (21.55±3.08). The lowest mean SBS was displayed in group ECL-ME (14.25±3.55). Mean SBS values for group ECL-C (21.55±3.08) and group ECL-V (20.74±4.15) were comparable (p <0.05). Similarly, SBS values of group ECL-BA (15.48±3.62) and group ECL-ME (14.25±3.55) were comparable (p <0.05). CONCLUSION: Dentin surface conditioned with Er,Cr: YSGG and bonded to C and V cements exhibit favourable bond strength values.
RESUMO
BACKGROUND: Although ample evidence supports connective tissue graft (CTG) use for root coverage, there is need for research on recipient site preparation approaches. The purpose of this study was to compare the outcomes of trapezoidal coronally advanced flap (CAF) and coronally advanced tunnel flap (TUN) when used in conjunction with CTG. METHODS: Forty-two patients presenting 42 single maxillary, Miller Class I and II, gingival recession defects were randomly assigned to receive either CAF + CTG (N = 21) or TUN + CTG (N = 21). Clinical, patient-centred, and aesthetic outcomes were assessed. RESULTS: Six months postoperatively, both groups resulted in significant reduction in recession depth and increases in keratinized tissue thickness and width. CAF + CTG and TUN + CTG mean root coverage was 87.2 ± 27.1% and 77.4 ± 20.4% respectively (p = 0.02). Complete root coverage was achieved in 71.4% and 28.6% of defects treated with CAF + CTG and TUN + CTG respectively (p = 0.01). At 7 days postoperatively, TUN + CTG patients reported significantly less pain experience (p = 0.04). Both approaches reduced dentine hypersensitivity by approximately 85% (p < 0.05). Patient-based aesthetic evaluation indicated significant improvement for both groups. Although patient- and professional-based aesthetic assessments revealed no differences between groups, tissue texture was significantly better for TUN + CTG (p = 0.02). CONCLUSIONS: For root coverage of single maxillary recession defects, CAF + CTG was more effective than TUN + CTG (ClinicalTrial.org-NCT02814279).

BACKGROUND: Sense of coherence (SOC) is a psychosocial factor capable of influencing perception of health, improving one's ability to manage life. It is the central construct of salutogenesis. SOC allows for identification and mobilization of resources to effectively manage or solve problems, promoting health and quality of life. Using Wilson-Cleary's conceptual model we hypothesized that SOC might contribute to self-perception of dental aesthetics. The aim of this study was to investigate whether SOC levels were related to self-perception of dental aesthetics against assessed normative orthodontic treatment need among adolescents. METHODS: A cross-sectional study was conducted with 615 male and female adolescents aged 12 to 15 years. Data collection comprised socio-demographic and socio-economic characteristics, SOC (SOC 13), self-perceived dental aesthetics (Oral Aesthetic Subjective Impact Scale), and assessment of orthodontic treatment need (Dental Aesthetic Index). Statistical analysis involved Pearson's chi-square test, Kruskal-Wallis test, Mann-Whitney test and multiple linear regression. Spearman's correlation coefficient was calculated for the determination of the strength of correlations among the numerical variables. The level of significance was set at 5% (p < 0.05). RESULTS: 50.1% of the participants were classified as having a high SOC (≥ median). Overall, SOC was associated with self-perceived dental aesthetics (p = 0.048). In the adolescents with no orthodontic treatment need, those with a low SOC perceived their dental aesthetics more negatively than those with high levels of SOC. The multiple regression analysis demonstrated an inverse relationship between SOC and: 1) age (p = 0.007), SOC being higher in the younger age group; 2) self-perceived dental aesthetics (p = 0.001), a higher SOC being associated with those who had a positive dental self-perception. CONCLUSIONS: SOC was associated with self-perceived dental aesthetics and adolescents with a high SOC were more likely to perceive their dental aesthetics more positively. SOC did not seem to influence self-perception of dental aesthetics in adolescents who were clinically assessed as having an orthodontic treatment need, however, in those where there was no orthodontic treatment need, a low SOC was associated with a negative self-perception of dental appearance.

OBJECTIVES: To investigate objective and patient-centred aesthetic outcomes for single-tooth implants in the anterior maxilla. MATERIALS AND METHODS: Ninety-eight patients (21 men and 77 women) with a mean age of 51.2 ± 3.8 years were included in this retrospective study. A total of 98 maxillary anterior single-tooth implant crowns with a mean functional time of 68.1 months (range 12-245) were evaluated. Aesthetic outcomes were measured by PES and WES. Statistical analysis was performed using the Mood's median and stepwise logistic regression with backward elimination to assess the effect of patient demographics, clinical parameters and surgical methods on aesthetic outcome (P < 0.05). RESULTS: The median PES was 11 and 94% of implants were deemed aesthetically acceptable. The median WES was 9 and 98% of implants were deemed aesthetically acceptable. The PES was positively influenced by the use of a connective tissue graft (CTG), adding 1 to the score (P = 0.002) and negatively influenced by membrane use (P = 0.026). Flapless techniques employed as part of an immediate implant placement protocol yielded better outcomes compared to flapped sites (P = 0.017). Immediate implant placement demonstrated greater variability in outcomes compared to early implant placement. CONCLUSIONS: Satisfactory objective and patient-reported aesthetic outcomes were achieved with dental implants replacing missing single teeth in the anterior maxilla. The use of CTG improved the aesthetic outcome mainly by increasing the alveolar process contour. Less variation in outcomes was observed with early (type 2) placement compared to immediate (type 1 placement).

Changes in occlusal vertical dimension (OVD) and age have been found to affect Smile Index (SI, width/height of smile). Limited information is available regarding the aesthetic effects of these changes. The objective of this study was to evaluate the attractiveness of digitally manipulated smile images with differences in SI and incisal edge position (IEP) judged by respondents in different age groups. A total of 12 smile images were generated with varying SI (3·5, 5·3, 7·2, 9·0) and IEP (High, Medium, Low). Fifty respondents each in four age groups (15-24, 25-39, 40-54, 55+) evaluated the attractiveness of the 12 images using a 0-10 visual analog scale (VAS, 10 being most attractive). A repeated-measures three-factorial mixed model assessed differences. SI, IEP and age of respondents were found to significantly influence attractiveness score (P < 0·01 for all). With all age groups combined, SI = 7·2/IEP = Medium was most attractive (VAS = 7·22), followed by SI = 9·0/IEP = Medium, and SI = 5·3/IEP = Medium (VAS = 6·53 and 6·48, respectively). SI = 3·5/IEP = High and SI = 3·5/IEP = Low were least attractive (VAS = 1·99 and VAS = 2·58, respectively). Age group significantly influenced aesthetic perception, with younger respondents more critical in differences in SI and IEP. SI and IEP significantly influenced attractiveness of the smile in all respondent age groups. Low SI (i.e. 3·5) combined with high or low IEP was unattractive. Medium SI to high SI (i.e. 5·3-9·0) combined with medium IEP were considered attractive.

The purpose of this study was to evaluate the training effect and to determine the optimal training protocol for a recently developed online colour training system. Seventy students participated in the evaluation. They first completed a baseline test with shade guides (SGT) and the training system (TST), and then trained with one of the three system training methods (Basic colour training for group E1, Vitapan Classical for E2, and Vitapan 3D-Master for E3) or shade guides (group C1) for 4 days. The control group (C2) received no training. The same test was performed after training and they finally completed a questionnaire. The correct matches after training increased in three experimental groups and group C1. Among experimental groups, the greatest improvement of correct matching number was achieved by group E3 (4·00 ± 1·88 in SGT, 4·29 ± 2·73 in TST), followed by E2 (2·29 ± 2·73 in SGT, 3·50 ± 3·03 in TST) and E1 (2·00 ± 2·60 in SGT, 1·93 ± 2·96 in TST). The difference between E3 and E1 was statistically significant (P = 0·036 in SGT, 0·026 in TST). The total average training time was shorter in group E2 (15·39 ± 4·22 min) and E3 (17·63 ± 5·22 min), with no significant difference between them. Subjective evaluations revealed that self-confidence in colour matching were improved greater in group C1 and E3. In conclusion, all tested sections of the system effectively improved students' colour-matching ability. Among system training methods, Vitapan 3D-Master showed the best performance; it enabled greater shade-matching improvement, it saved time and was superior in subjective evaluations.

The objectives of this study were to investigate the degree of effective recognition by professionals of patient-estimated oral aesthetic impairment and the most reliable aspects in such recognition. Participants consisted of 95 patients with partial dentition in need of prosthodontic replacements. The oral aesthetics was professionally evaluated using the Prosthetic Esthetic Index (PEI), compiling 13 aesthetic aspects and an overall evaluation. The patient-reported impairment was evaluated using the Oral Health Impact Profile Aesthetic (OHIP-Aes) and the Oral Esthetic Scale (OES). Background variables were as follows: gender, age, work situation, education level, marital status, number and location of teeth, wearing a removable dental prosthesis (RDP) and smile line. A significant correlation was found between the overall professional evaluation and the OHIP-Aes score (R = 0·43, P < 0·05), the OES score (R = 0·46, P < 0·05) and the overall patient evaluation (0·35, P < 0·05). Correlations of the 13 specific aspects of the PEI with the patient-reported evaluations were generally small to moderate: the aspect 'discoloration of the teeth' showed the highest correlation. The multivariate analyses showed that up to 57% of the patient-reported impairment could be explained by the professionally evaluated oral aesthetic in combination with background variables. Discoloration of the teeth was the greatest explanatory variable, but also dental arch symmetry, and position and colour of the teeth were significant aspects. A high percentage of the patient-reported aesthetic impairment can be recognised by the professionals. The most reliable aspect is discoloration of the teeth, but also dental arch symmetry, and the position and colour of the teeth are important for recognising the aesthetic impairment.

OBJECTIVE: The aim of this study was to develop a reliable and valid Nepali version of the Psychosocial Impact of Dental Aesthetic Questionnaire (PIDAQ). DESIGN: Cross-sectional descriptive validation study. SETTINGS: B.P. Koirala Institute of Health Sciences, Dharan, Nepal. METHODS: A rigorous translation process including conceptual and semantic evaluation, translation, back translation and pre-testing was carried out. Two hundred and fifty-two undergraduates, including equal numbers of males and females with an age ranging from 18 to 29 years (mean age: 22·33±2·114 years), participated in this study. Reliability was assessed by Cronbach's alpha coefficient and the coefficient of correlation was used to assess correlation between items and test-retest reliability. The construct validity was tested by factorial analysis. Convergent construct validity was tested by comparison of PIDAQ scores with the aesthetic component of the index of orthodontic treatment needs (IOTN-AC) and perception of occlusion scale (POS), respectively. Discriminant construct validity was assessed by differences in score for those who demand treatment and those who did not. RESULTS: The response rate was 100%. One hundred and twenty-three individuals had a demand for orthodontic treatment. The Nepali PIDAQ had excellent reliability with Cronbach's alpha of 0·945, corrected item correlation between 0·525 and 0·790 and overall test-retest reliability of 0·978. The construct validity was good with formation of a new sub-domain 'Dental self-consciousness'. The scale had good correlation with IOTN-AC and POS fulfilling convergent construct validity. The discriminant construct validity was proved by significant differences in scores for subjects with demand and without demand for treatment. CONCLUSION: To conclude, Nepali version of PIDAQ has good psychometric properties and can be used effectively in this population group for further research.

Discrepancies in tooth size and shape can interfere with smile harmony. Composite resin can be used to improve the esthetics of the smile at a low cost while offering good clinical performance. This article presents an approach for restoring and correcting functional, anatomic, and esthetic discrepancies with minimal intervention, using composites and a direct adhesive technique. This conservative restorative procedure provided the patient with maximum personal esthetic satisfaction.

BACKGROUND: Coronavirus disease 2019 (COVID-19) has badly affected the mental health, quality of life, and self-esteem of students worldwide. OBJECTIVE: The current study aimed to evaluate the psychological impact and self-esteem of dental students using Rosenberg self-esteem scale and PIDAQ during the COVID-19 pandemic. METHOD: This cross-sectional research was conducted amongst the dental students studying at various dental colleges in Karachi, Pakistan from January to May 2022. Evaluation of psychological aspect and self-esteem of students was carried out using "Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ)", and "Rosenberg self-esteem scale" as perceived by students during the pandemic. For data analysis SPSS v24 was used. Data analysis comprised of descriptive analysis, Spearman correlation, One-way Anova and Linear regression. The level of significance of p value was less than 0.05. RESULTS: Overall 332 students participated, among which there were 181 females (54.5%), 151 males (45.5%). Dental self-confidence showed a negative relationship with social influence, psychological effect, and aesthetic concern, while it was positively linked with self-esteem during the pandemic. Social impact demonstrated association with psychological impact, aesthetic concern, and self-esteem, while it was negatively correlated with dental confidence. Rosenberg score showed positive correlation with all the variables. Statistically significant association was identified for variables when compared with gender. Regression analysis indicated association of age with dental confidence and RSS, while gender with social influence. CONCLUSION: The pandemic, aside from affecting the health of individuals worldwide, also badly affected the well-being, mental health, and self-esteem of the dental students. Dental aesthetics plays a crucial role in the mental wellbeing and self-esteem of the students.

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.
