Vertical Gingival Display Changes Associated with Upper Premolars Extraction Orthodontic Treatment: A Prospective Clinical Trial.

This clinical research paper – recently published in the November issue of the Journal of Clinical and Experimental Dentistry (J Clin Exp Dent) and which I’ve had the pleasure to have been a part of – aimed at investigating and comparing vertical gingival display (VGD) changes associated with upper (first vs second) premolars extraction during orthodontic treatment.

Sixty orthodontic patients were included in the study , done at the Postgraduate dental teaching clinics at Jordan University of Science and Technology (JUST). They were treated with upper first or second premolars extraction according to the underlying problem and the individualized treatment plan of each patient. Full Records (radiographs, study casts and standardized clinical photographs) were taken for all subjects pre- and post- orthodontic treatment. Outcome measures: Pre- and post-treatment VGD, lip length in static and dynamic positions and the amount of upper teeth retractions were recorded.
