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).

Juxta-Apical Radiolucency: Prevalence, Characterization, and Association With the Third Molar Status.

Purpose: This study aimed to investigate the prevalence of juxta-apical radiolucency (JAR), assessing its association with third molar status and describing its radiologic features through panoramic radiography.

Materials And Methods: We evaluated 1,050 radiographs (1,830 third molars) for the presence of JAR. The JAR and control groups were classified according to the third molar's angulation, impaction, and root development.

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.

Juxta-apical radiolucency: relation to the mandibular canal and cortical plates based on cone beam CT imaging.

Objective: To evaluate the relation of juxta-apical radiolucency (JAR) to the mandibular canal and cortical plates on cone beam computed tomography images, as well as to assess whether the presence of JAR is related to the position of the mandibular canal.

Study Design: Forty-seven JAR cases were evaluated by cone beam computed tomography. JAR position and its relationship to the mandibular canal and cortical plates were investigated.

The impact of nonsyndromic oral clefts on family quality of life.

This study aimed to assess the impact of nonsyndromic oral cleft (NSOC) on families' quality of life (QoL) using the Brazilian version of the Family Impact Scale (B-FIS). A hospital-based case-control study was conducted with NSOC cases and unaffected controls recruited at Dental Clinic in Federal University. The mean B-FIS scores were 10.
