title: Panoramic radiographs: a tool for investigating skeletal pattern.
abstract: The objective of this study was to investigate the possibility of enhancing the clinical versatility of the panoramic radiograph, which is an indispensable tool for dental diagnosis. The material of this study consisted of lateral cephalograms and panoramic radiographs obtained from 30 patients. A correlation test was performed between the parametric measurements, and the predictability level of the cephalometric measurements from panoramic radiograms was determined by using regression equations. The equations showed that the Go-Gn/S-N, ANS-PNS/Go-Me (palatal plane/mandibular plane), and Co-Go/Go-Me parameters could be predicted from panoramic radiographs within statistically significant levels, and their predictability levels were 20.6%, 15.6%, and 11.2%, respectively. Statistically significant correlations and predictability levels were also determined for the cephalometric and corresponding panoramic parameters in which Frankfort horizontal plane was used. It can be concluded that even though panoramic radiographs provide information on the vertical dimensions of craniofacial structures, clinicians should be vigilant when predicting skeletal cephalometric parameters from panoramic radiographs, because of their lower predictability percentages.
