title: Reliability of ARCUSdigma (KaVo) in diagnosing temporomandibular joint pathology.
abstract: OBJECTIVE
  to assess the sensitivity and specificity of ARCUSdigma in diagnosing temporomandibular joint (TMJ) pathology (TMD).
  
  
  METHODS
  102 TMJs were exmined with ARCUSdigma and "Cadiax Diagnostic" electronic axiography system. Free opening, free protrusion and mediotrusion were recorded with both devices. Guided opening and guided protrusion were examined with "Cadiax Diagnostic". Using free opening and free protrusion diagnosis was established.
  
  
  RESULTS
  Sensitivity of ARCUSdigma was found to be 84,21% and 92,86% for the right and left TMJ respectively. Specificity - 93,75% and 95,65% for the right and left TMJ. The 95% confidence interval for sensitivity and specificity was calculated.
  
  
  CONCLUSIONS
  Within the limitations of this study, ARCUSdigma appeared to be a valuable supplement to clinical findings in diagnosing TMDs.
