January JADA Examines Changes In Facial Profile Resulting From Orthodontic Treatment.

The ADA News (1/4, Manchir) reports that a systematic review published in the January issue of The Journal of the American Dental Association finds “no significant difference exists between the changes in patients’ facial profiles as a result of orthodontic treatment with and without extraction of four premolars in terms of esthetic outcomes.” After reviewing “randomized clinical trials and observational studies” that compared the two types of treatment, researchers concluded that “for patients who initially had greater lip protrusion and more convex facial morphologies, premolar extractions tended to be beneficial to the soft tissue structure.” However, the article also found patients treated without extractions endured “significantly shorter” duration of orthodontic treatment. “This research will help both clinicians in their decision making, and researchers in preparing new studies,” said Dr. Walter Iared, corresponding author of the article and a researcher at the department of emergency medicine and Evidence-Based Medicine at the Federal University of Sao Paulo in Brazil.
