title: [Effect of right chewing-side preference on morphological temporomandibular joint changes].
abstract: OBJECTIVE
  To explore the effect of right chewing-side preference on temporomandibular joint with cone-beam computed tomography (CBCT).
  
  
  METHODS
  Fifty-two patients who were diagnosed as right chewing-side preference were selected and scanned by CBCT in the intercuspal position. The interested region was chosen to reconstruct and the images of bony structure of TMJ at axial view, coronal position, sagittal position, oblique position parallelled to the long axis of condyle and oblique position vertical to the long axis of condyle were evaluated. The data was analyzed with SPSS12.0 software package for paired t test.
  
  
  RESULTS
  There was significant difference between the habitual and unhabitual sides of the joint space of 60° and 90° at oblique position parallelled to the long axis of condyle (P<l0.05), as well as the joint space of 120° and 150° or the thickness of neck of condyle at sagittal position and the oblique position vertical to the long axis of condyle (P<0.01). No significant difference was found in the rest measuring values.
  
  
  CONCLUSIONS
  The results indicate that right chewing-side preference affects the morphology of temporomandibular joint. Supported by National Natural Science Foundation of China (Grant No.30772450) and the Nursery Fund of General Hospital of Chinese PLA (Grant No.09KMM11).
