Introduction: Body image is a multidimensional concept defined as the representation that an individual makes of his/her body. The attitudinal dimension of body image is composed of affective, cognitive, behavioral aspects and general subjective satisfaction. Therefore, the construction of this concept occurs by the simultaneous structuring of these aspects. There is no instrument in the literature that evaluates this aspect considering all the parts of the body simultaneously. For this reason, association of measuring instruments is necessary. It should be emphasized that studies generally do not consider the impact of orofacial esthetic in this context. This fact deserves attention since the face may be important in the composition of the individual's body image and this may interfere with his/her general well-being. Aims: i. to elaborate a concept of body image associating different component aspects including orofacial esthetic, ii. to estimate the impact of body image components on the perception of orofacial esthetic of adult individuals, iii. to verify the influence of orofacial esthetic on the oral health impact profile on adult, iv. to verify the relation of perception of orofacial esthetics and body image with body composition, v. to evaluate the influence of body image, oral health impact profile, satisfaction/psychosocial impact of orofacial esthetic, demographic and clinical characteristics on the satisfaction with life of adult individuals, vi. to verify the affective reactions through the facial expressions of individuals with different profiles of concern with esthetics facing visual stimuli related to the mouth appearance, and vii. compare the attractiveness of the smile reported by dentists and adult individuals. Methods: This is an observational study with a non-probabilistic sampling design. Two study samples, adult individuals (age between 18 and 40 years) from the community (normative sample) and individuals seeking dental treatment at the School of Dentistry will be delineated. The sample size should be 700 individuals for each sample. Considering that the concept of body image is perceived differently between men and women, the minimum sample size should also be reached for each gender. Demographic and clinical information will be collected. Body image and orofacial esthetic will be evaluated by the instruments: Attention to Body Shape Scale (ABS), Social Physique Anxiety Scale (SPAS), Body Checking and Avoidance Questionnaire (BCAQ), Escala Situacional de Satisfação Corporal (ESSC), Orofacial Esthetic Scale (OES) and Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ). The oral health impact profile on individuals' lives will be evaluated by the Oral Health Impact Profile-14 (OHIP-14) and life satisfaction will be estimated by Satisfaction with Life Scale (SWLS). The face, construct and discriminant criterion validities will be estimated. Confirmatory factor analysis with robust estimation of Weighted Least Squares Mean and Adjusted Variance will be used. The internal consistency (a) and composite reliability will be estimated. Structural equation analysis will be used to prepare four structural models to respond the proposed aims. Models should be tested for total sample and for subsamples. Scores of satisfaction with orofacial esthetics and of the psychosocial impact of esthetics on individuals' lives will be calculated. Participants will then be allocated into 2 groups considering the 75th and 25th percentiles of each scale. Facial expressions will be filmed and the affective reactions of the individuals of these groups facing visual stimuli of images of the mouth. The intensity and valence of six basic emotions (happy, sad, angry, surprised, scared and disgusted) and neutral expression will be estimated and compared between groups using ANOVA. Dentists will also evaluate the images and the intensity and valence obtained will be compared with those of the sample. (AU)
