Impact of CBCT acquisition protocols and artifact reduction filters on diagnosing vertical root fractures.

Aim: To evaluate the impact of acquisition protocols and artifact reduction filters in cone beam computed tomography on diagnosing vertical root fractures in endodontically treated teeth with and without intraradicular posts.

Materials And Methods: We analyzed 480 tomographic images acquired from two J. Morita scanners (0.

Development of a correction coefficient for radiographic evaluation of the alveolar bone crest: a pilot study.

Objectives: To analyze the differences in cusp height on radiographs, establishing proportional relationships between cusp and alveolar bone crest (ABC) measurements. The goal of this study was to develop a correction coefficient by considering this proportion.

Materials And Methods: Twenty-one artificial teeth, molars and premolars, and bovine ribs were used.

Influence of age and experience with magnification on locating the second mesiobuccal canal in maxillary first molars: A preliminary study.

The aim was to evaluate the effectiveness of clinical methods in identifying the presence of second mesiobuccal canal in maxillary first molars. The influence of age and experience with microscopy was also assessed. Sixty six teeth were selected and the mesiobuccal canal was confirmed in all of the samples by Cone-Beam Computed Tomography.

Association between internal carotid artery calcifications detected as incidental findings and clinical characteristics associated with atherosclerosis: A dental volumetric tomography study.

Purpose: To evaluate the presence of calcifications in the internal carotid artery (ICA) in cone-beam computed tomography (CBCT), and to verify the association of these findings with sex, age, dental condition, and risk factors associated with vascular disorders.

Methods: The CBCT scans used in this study were obtained from the database of a private dental clinic requested for the planning of rehabilitation with dental implants. The selection criteria were patients aged 40 years and above.

Exploring digital filters for internal root resorption: how can we improve the diagnosis of small lesions?

Objectives: This study aimed to evaluate the impact of enhancement filters in detecting small simulated internal root resorptions (IRR).

Methods:: Forty-two extracted human teeth were sectioned, connected, and stored in a dry human jaw and X-rayed with photostimulable phosphor plates (PSPs), composing the control group (CG). In the middle-third of the root canals, IRR lesions were simulated using Da Silveira protocol.

Benefits of using a photostimulable phosphor plate protective device.

Objectives: To develop and test a protective device (PD) to increase the resistance of photostimulable storage phosphor (PSP) plate to compressive load, and assess the resulting image quality.

Methods: Two prototypes, polyvinylchloride sheets of 0.3 mm and 0.
