ABSTRACT This study investigated the influence of changes in tooth color on judgments of facial attractiveness. Standardized photographs were presented, and teeth were digitally manipulated (main categories: original, whitened, colored; filler category: impaired). Participants were instructed to evaluate the faces for attractiveness. Additionally, they were asked to name facial features they found either positive or negative with regard to attractiveness. Whitened teeth were mentioned more often in a positive way but did not improve participants' assessment of attractiveness. A colored tooth did not attract attention, and the attractiveness judgment did not worsen. Tooth color is thus not necessarily perceived and does not have a major impact on facial attractiveness.

    ABSTRACT: Objective. To identify participants' satisfaction with appearance and the desired treatment to improve aesthetics. Materials and Methods. 220 participants (127 males and 93 females, mean age = 21.4 ± 1.5 years) were recruited into the study. A structured questionnaire was used to assess patients' satisfaction with appearance and what treatment they desire to improve aesthetics. Participants scored the level of satisfaction with appearance using visual analogue scale. Results. The VAS mean score of satisfaction with general appearance was 6.8 ± 2.3. Half participants were dissatisfied with tooth appearance and 65.9% were dissatisfied with tooth colour. Higher VAS scores were associated with higher desire for all treatments that improve tooth appearance (P < .05). Dissatisfaction with tooth appearance increased with increased dissatisfaction with teeth colour, feeling of poor tooth alignment, presence of fractured anterior teeth, and increased desire for orthodontic, crowns, and dentures treatments (P < .05). Dissatisfaction with tooth colour was associated with increased desire for tooth whitening and tooth coloured fillings (P < .05). Conclusions. Participants had high levels of dissatisfaction with tooth appearance and tooth colour. Dissatisfaction with tooth colour contributed to the increased dissatisfaction with tooth appearance. Dissatisfaction with tooth appearance, colour, alignment, and condition was significantly related to high desire for aesthetic treatments.

    ABSTRACT: Objectives. To illustrate some of the fundamental orthodontic guidelines for maintaining the harmony of the dento-periodontal unit and the face, which includes a dynamic component: the smile. Materials and methods. This dossier examines the golden ratio of dental to gingival components in the smile; the relationships between teeth, gums, and lips in the dynamic smile; the effects on the smile of excessively large buccal corridors and their relation to the position of the teeth within the dental arches; and the role of the smile the overall facial esthetics. It also reviews the modifications that will be produced by aging in the soft and hard tissues of the face, for the orthodontist must always evaluate the patients face prospectively: not only as it appears at the time of treatment, but also as it will appear after the passage of time. Results and conclusions. Esthetics is a relative concept, and it is difficult to establish rigid guidelines for producing a beautiful smile and a beautiful face. However, orthodontics has introduced some general rules that can help maintain the harmony of the face through the dynamic component of the smile.

    ABSTRACT: Dental appearance may play a key role on the way we develop a first impression of another person. To test whether relatively minor changes in the lightness of tooth colour would influence the perceived social appeal (social, intellectual, psychological and relational abilities) of an unknown male and unknown female, this cross-sectional study was performed on 555 Spanish adults. The two major independent variables related to the photograph were tooth lightness (computer-derived), divided into three levels that included lightened teeth, natural teeth and darkened teeth, and the gender of the observed face. Moreover, six independent variables related to the observer were assessed (age, gender, educational level, place of residence, frequency of brushing and self-reported health status). The dependent variables were scored on five-point Likert scales designed to quantify four domains (social, intellectual, psychological and relationship competences) of the Social Appeal Scale (SAS). Tooth lightness influences the perception of social appeal in all dimensions, as darkened smiles received significantly poorer scores than natural-colour smiles, but these were also worse than lightened smiles. A logistic regression analysis revealed that the major predictor of social appeal was tooth lightness, and for each increment in lightness (from darkened to lightened smiles), the odds ratio (OR) of positive values being perceived increased significantly in all items (from 2·3 in Popularity to 6·9 in Happiness). A perceptible change in dental lightness is the strongest factor associated with the dental attractiveness stereotype, affecting significantly the 12 traits assessed, but mainly the Happiness, Social Relations and Academic Performance.
