The investigators studied the case histories of 590 patients between 7 and 18 years of age attending the orthodontic clinic at Case Dental School. They recorded age, gender, height and weight (abstracted from patient chart) along with tongue length and hyoid-to-mandibular-plane distance (measured from lateral cephalograms) in a linear model to generate a CRI score. The 30 patients with the highest and 30 patients with the lowest CRI scores were asked to undergo unattended in-home sleep monitoring to determine their RDI score.
Since children in this small pilot sample with high CRI scores exhibited somewhat higher RDI scores than those with low CRI scores, it may be possible to use cephalometric radiographs to identify teenagers at risk for sleep-disordered breathing.
This is a summary of abstract #2531, by M.G. Hans and co-workers, from Case Western Reserve University, Cleveland, OH, to be presented at 2 p.m. on Friday, March 11, in Exhibit Hall E-F of the Baltimore Convention Center, during the 83rd General Session of the International Association for Dental Research.
