Abstract

ObjectiveTo establish the frequency of patients selected as attractive showing the golden ratio on their faces according to the Marquardt mask and a class I molar relationship. MethodologyObservational research, transversal, retrospective and comparative study. Were collected 65 pictures (19 male and 46 female) from pre-orthodontic treatment patients at UNITEC Orthodontics Clinic with attractive faces according to beauty criteria established by the authors. Molar class was also evaluated among patients. sample sizediscretionary. sample typenon-probabilistic. The pictures were shown to UNITEC Orthodontics graduate students who were given an evaluation sheet on which they graded patients from the least to the most attractive on a 1 to 5 scale. A study group was made from the results. Paint Shop Pro sc09960 version 7 was used to analyze the images by placing a Marquardt Mask on top of the patient’s picture. ResultsOut of the 65 pictures, 64.6% were described as attractive (42 patients) while 35.4% were found not attractive (23 patients). Out of the attractive patients, 57.1% were well proportioned according to the Marquardt Mask and 42.9% were not proportioned. ConclusionsThe authors concluded that attractive patients are not always well proportioned. They also don’t present an Angle class I molar relationship.
