Orthodontic patients of African descent often seek some measure of reduction in profile protrusion. Lip retraction, however, seems to imply a need for premolar extraction. But in a nonextraction era, what does orthodontics have to offer the bimaxillary protrusion patient? To a considerable extent, it depends on what the patient wants and what treatment can provide. The present study was designed to address these questions by comparing the esthetic impact of extraction and nonextraction therapy on two morphologically similar samples of African American patients with Class I and II malocclusions. In addition to the patients, four panels of judges (black and white orthodontists and black and white laypersons) were asked to compare the pretreatment and posttreatment profile tracings and to quantify their perceptions of the esthetic impact of the change that occurred during treatment. Although there was a strong correlation among the various groups' ratings, there were a number of"
