Does the aesthetic perception of protrusion correction change if the face is evaluated from the frontal or profile perspectives?

Objective: verify if reduction of facial convexity obtained with dental extractions promotes changes that are noticeable in frontal view. Compare whether the correction different degrees protrusion distinct aesthetic perception and profile analysis. Methods: two brown female patients class I malocclusion, incisors convex were selected. Patients displayed initially magnitude (moderate x excessive) both treated premolars extraction anterior teeth retraction. Two sets images composed enclosing lateral records at before after treatment. Sample 194 laypeople evaluated answered following questions: (1) Can you notice any differences between correspondent presented? (yes or no). (2) Which image do find most attractive? (3) Assign a score for each from 0 to 10. Results: position face had an influence on moderate protrusion. In this case, less negative impact aesthetics was evidenced when frontally. addition, resulting treatment more analyzed perspective. Regarding excessive protrusion, no significant observed comparing views, indicating effects can be perceived equally views. Conclusions: generates impacts easily noticed However, promoted by analysis same way as profile.
