background and aims. in periapical radiographic technique, the changes will be visible only after considerable deposition or resorption while digital subtraction technique visualizes slight density changes. this study was aimed to compare visualization of density changes in conventional periapical radiographs and digital subtraction technique with or without image enhancement. materials and met...
Objectives: To assess and compare five diagnostic imaging methods used in the identification of periapical diseases, of different diameters, mechanically simulated. Methods: The sample of the present study consisted of 12 dried human mandibles. Digital panoramic radiography, conventional and digital periapical radiography (charged couple device and photo-stimulable phosphor plate), and high-res...
Statement of Problem: One of the dental lesions which is mainly diagnosed by periapical radiography is apical root resorption Diagnosis of the presence and extension of this lesion can put some effects on its treatment plan and prognosis. Purpose: The aim of the present study was to evaluate the efficacy of periapical radiography on apical root resorption diagnosis. Materials and Methods: In th...
The aim of this study was to determine the relationship between loss of radiographic crestal bone height in panoramic, bitewing and periapical radiography and to probe the attachment loss after periodontal treatment. Radiographic and probing measurements were made at baseline and after one year The population in the study consisted of 21 individuals, 13 females and 8 males, ages 18-59 [mean 35....
A 20-year-old man presented with the history of pain and swelling in the anterior maxillary segment. The periapical radiography was indicative of a dental anomaly in right maxillary lateral incisor. Due to the insufficient information from conventional radiography, cone-beam computed tomography (CBCT) was ordered. CBCT showed apical root resorption, large apical lucency and two separate canals ...
Purpose: To investigate peri-implant bone resorption around 108 ITI dental implants 1 year after prosthetic loading using extraoral panoramic, conventional intraoral periapical, and digital radiologic techniques. Materials and Methods: A total of 108 implants were placed (59 in the maxilla and 49 in the mandible) in 42 patients (16 men and 26 women) with a mean age of 44.2 years (range 14 to 68...
normal 0 false false false en-us x-none fa microsoftinternetexplorer4 introduction : alveolar bone level is changed due to the balance between bone formation and resorption. radiographic examination has an important role in the diagnosis and treatment of periodontal diseases. this study was performed to compare the accuracy of vertical bitewing and periapical radiography in anterior mandibular ...
Periapical radiography is essential in diagnosis, treatment planning and follow-up in endodontics. However, image interpretation can be confounded by geometric distortion, superimposition of regional anatomy and technique errors. These problems can be overcome by utilizing small or limited-volume cone beamcomputed tomography imaging techniques, which produce accurate 3-D images of the teeth and...
