Authors’ response
We want to thank the authors of this letter to the editor for their comments regarding our article. We are fully aware of the limitation of using Hounsfield units (HU) to…
Use of Hounsfield units in cone-beam computed tomography
The article “Hounsfield unit change in root and alveolar bone during canine retraction” focused on HU changes in the alveolar bone and root surface as the canines were moved by…
Solving the faculty shortage might require more than money
Just how big a problem is faculty recruitment and retention? Consider a few numbers. About 2 decades ago, a quarter of orthodontics departments were seeking to fill vacant positions; during…
The image we cast
Over the years, many articles have appeared in the AJO-DO regarding public relations and image. These have included discussions of the many “publics” that are involved, including our relationships with…
Three-dimensional finite element analysis of maxillary protraction with labiolingual arches and implants
