Influence of CBCT parameters on image quality and the diagnosis of vertical root fractures in teeth with metallic posts: an study.

Objectives: The aim of this study was to evaluate the influence of peak kilovoltage (kVp) and a metal artifact reduction (MAR) tool on image quality and the diagnosis of vertical root fracture (VRF) in cone-beam computed tomography (CBCT).

Materials And Methods: Twenty single-rooted human teeth filled with an intracanal metal post were divided into 2 groups: control ( = 10) and VRF ( = 10). Each tooth was placed into the socket of a dry mandible, and CBCT scans were acquired using a Picasso Trio varying the kVp (70, 80, 90, or 99), and the use of MAR (with or without).

Brightness and contrast adjustments influence the radiographic detection of soft tissue calcification.

Objective: To assess the influence of subjective enhancement of brightness and contrast of digital panoramic radiographs on the detection of soft tissue calcifications.

Materials And Methods: In this observational study, 500 digital panoramic radiographs were evaluated by two examiners in consensus, who scored the images for the presence of calcifications for each right and left side of the image. After 30 days, all images were revaluated under subjective manipulation of digital brightness and contrast.

Influence of acquisition parameters on the evaluation of mandibular third molars through cone beam computed tomography.

Objectives: The aim of the study was to assess the influence of cone beam computed tomography (CBCT) acquisition parameters on the evaluation of mandibular third molars and their relationship to the mandibular canal.

Study Design: Eight dry human mandibles with 13 mandibular third molars were scanned with one CBCT unit. Voxel size (0.
