Lateral transcranial radiography of temporomandibular joints. Part II: Image formation studied with computerized tomography.
Two series of radiographs of 15 subjects (30 TMJs overall) were compared in order to evaluate the reliability of OLTP carried out with different techniques: individualization of incidence through radioscopy (OLTP/fluo) or through the submental vertex method (OLTP/sub). Reasons for formation of noninterpretable radiographs (prevalently with OLTP/sub) and for diagnostic errors in judging condyle position were evaluated for each technique through a CT scanning study of the same patients. The reasons for the wide range of constancy of results found in OLTP/fluo are also discussed. Overall the study demonstrated reliability of the OLTP carried out with the technique of individualizing the incidence through fluoroscopy.
