It is a great idea to develop the AJO-DO Resource Center (Turpin DL, Behrents RG, Abdelkarim AA. Proposed AJO-DO Resource Center on cone-beam computed tomography imaging. Am J Orthod Dentofacial Orthop 2014;145:711). It would be great to include information on coregistering of cone-beam computed tomography (CBCT) scans and 3-dimensional face surface scans. I am working on some studies looking at facial biomarkers that relate to allergic and airway-compromised children and adults. These can only be quantified from 3-dimensional facial surface images. If these biomarkers show up on a child’s face, then it might give us a reason to look deeper at the airway, using CBCT, especially in the new paradigm of early airway disorders that might lead to future sleep disorders (eg, obstructive sleep apnea) and chronic diseases (heart disease, stroke, and so on) later in life. Dr Steve Schendel and his colleagues at Stanford University and others are studying obstructive airway and its effect on craniofacial growth in children and the long-term health effects in adults. It is interesting that we as orthodontists might see these disorders at their beginning. I do think that CBCT can help us to understand these relationships better in the future.
