Abstract
This investigation was conducted to evaluate the periodontal, cephalometric, and esthetic sequelae in a small sample of clear-cut four first premolar extraction cases that were treated by a nonextraction modality. These patients were compared to an equal number of correctly treated four first premolar extraction cases and another group of nonextraction cases. Periodontal pocket depths and width of keratinized gingiva were measured clinically. Pre-treatment and post-treatment cephalometric measurements were also collected. Patients were asked to rate their own perception of the extent of esthetic change in their pre- and post-treatment facial profiles on a visual analog scale. A similar visual analog scale was used by laypersons to evaluate the esthetics of post-treatment facial profile photographs. Results showed that the patients in the ‘wrong treatment’ group had significantly less keratinized gingiva associated with both upper and lower anterior teeth as well as the upper and lower left first molars. Cephalometric measurements showed an excessive increase in the protrusion of teeth in patients who received the wrong treatment as compared to both control groups. Patients who were treated with first premolar extractions reported significant favorable profile changes. Laypersons could not detect any differences amongst the three groups in post-treatment profile esthetics. This study could not demonstrate a benefit to the patient from an ill-applied, fashionable nonextraction therapy.
