Introduction Dental implant placement in the region of the mental foramen has been known to cause neurosensory deficit due to nerve injury.1-4 The identification and preservation of the anterior loop (AL) of the mental nerve is an important means of avoiding such neurosensory deficit.5-7 There is a general consensus that plain film radiographs are inadequate for the accurate identification of t...

HEIDI KOHLTFARBER, DDS: A Comparison of 2D versus 3D Radiography in the Diagnosis and Treatment Planning of Root Canal Treated Teeth with Periapical Lesions (Under the direction of Donald Tyndall) Objectives: The aims of the study were to assess diagnostic efficacy in lesion detection, evaluate the effect of cone beam CT on treatment planning and clinician confidence. Methods: Forty digital per...

The purpose of this study was to evaluate a new periapical index based on cone beam computed tomography (CBCT) for identification of apical periodontitis (AP). The periapical index proposed in this study (CBCTPAI) was developed on the basis of criteria established from measurements corresponding to periapical radiolucency interpreted on CBCT scans. Radiolucent images suggestive of periapical le...

INTRODUCTION Vertical root fracture (VRF) is the longitudinal fracture of the root in endodontically treated teeth. Considering the limitations of two-dimensional radiographic images in detection of VRF and introduction of cone-beam computed tomography (CBCT), this study was designed to find the sensitivity, specificity and accuracy of CBCT and periapical (PA) radiography in detection of VRFs. ...

Retrieval of cement-retained implant prostheses can be more demanding than retrieval of screw-retained prostheses. This case report describes a simple and predictable procedure to locate the abutment screw access openings of cementretained implant-supported crowns in cases of fractured ceramic veneer. A conventional periapical radiography image was captured using a digital camera, transferred t...
