Abstract

LINEAR TOMOGRAPHY is one of the imaging modalities used for patient assessment prior to DENTAL IMPLANT placement. This research evaluates the accuracy and validity of LINEAR TOMOGRAPHY in the imaging of human mandible. Eight edentulous mandibles were prepared. They were sectioned sagittaly in the midline and eight hemisectioned mandibles were selected. LINEAR TOMOGRAPHY was applied for two locations in each mandible, one in 2nd premolar and the other in 2nd molar area. These locations were sectioned in coronal plane using a thin saw and the following parameters were measured: A) Bucco lingual width in three vertical distances from surface: 5mm, 10mm and 15mm B) Vertical distances between the superior border of mandibular canal and superior surface of alveolar bone. These measurements were compared with their counterparts in tomographic images. From this comparison we concluded that there is no significant difference between LINEAR TOMOGRAPHY and direct observation in measuring the distance between superior bone surface and superior border of mandibular canal (P>0.05). There is significant difference when we consider horizontal measurements with the exception of buccolingual width in premolar area at the 5mm vertical distance from the surface which shows no significant differences (P> 0.05). The validity of tomographic technique is acceptable since there were no significant differences between different radiologists' observations and between one radiologist's observation in different sessions (P> 0.05).
