Efficacy of several digital radiographic imaging systems for laboratory determination of endodontic file length

Abstract

The three digital radiographic imaging systems were precise. The CDR Wireless system was significantly more accurate in determining endodontic file lengths, and similarly to Digora Optime, was considered the least difficult to use when assessing endodontic file lengths.

Influence of cone-beam computed tomography image artifacts on the determination of dental arch measurements

“…10 Despite the high resolution and great image quality presented by current digital images, it is important to check if they allow better accuracy and precision on different tasks. 11 Several studies have evaluated the ability of CBCT in measuring the dental arch and surrounding structures. 1,2,4,5,8,9 Mullen et al 5 and Luu et al 12 demonstrated that CBCT is as accurate as DPM in the attainment of measurements, which is in agreement with the present study.…”

Image quality evaluation of eight complementary metal-oxide semiconductor intraoral digital X-ray sensors

“…Intraoral solid‐state sensors have been tested in different settings. Nonetheless, such studies tested a small number of sensors that generated images which were evaluated by a relatively small number of clinicians. This study has greater validity than previous studies, all of which used fewer types of sensors, fewer evaluators or both.…”

Gray scale inversion in digital image for measurement of tooth length

“…Studies determining file lengths in the root canal have been performed previously (6,7,14,16). This measurement does not address the exact clinical procedure during an endodontic treatment.…”

“…In the present study, endodontic files were introduced in the root canal according to the method proposed by Ingle (15). Tooth length was obtained from a previous study (7) in which, after an initial film-based radiograph, the distance between the incisal border and the apical root was measured.…”

“…Ten phantoms containing 4 extracted human permanent single-rooted teeth mounted in a stone plaster block were used. All of the teeth had standard access cavities and the record of their length value from a previous study (7). In an effort to simulate the periodontal ligament space and the trabecular bone, the root of each tooth was coated with a layer of wax and the plaster was mixed with powdered rice in a ratio of 1:1.…”
