Cone-beam computed tomographic study of the persistent foramen tympanicum according to age, sex, and skeletal patterns.

This cross-sectional study evaluated the influence of prevalence, laterality and diameter of persistent foramen tympanicum (PFT) in cone beam computed tomographic (CBCT) scans of adult patients with different sagittal skeletal patterns, sex and age. CBCT of 510 patients were assessed for the presence of PFT. Skeletal pattern, age and sex of the affected patients were recorded, as well as laterality and diameter of PFT.

Imaginology Tridimensional Study of Temporomandibular Joint Osseous Components According to Sagittal Skeletal Relationship, Sex, and Age.

Objective: To assess the temporomandibular joint (TMJ) osseous components morphology and the condyle position in patients with different sagittal skeletal relationships, sex, and age, using cone-beam computed tomography (CBCT).

Methods: The CBCT images of 180 asymptomatic patients (60 class I, 60 class II, and 60 class III) were assessed retrospectively. Groups were also divided according to age (<40 years, n = 90; ≥40 years, n = 90) and sex (male, n = 90; female, n = 90).

Cone beam computed tomography study of osteoarthritic alterations in the osseous components of temporomandibular joints in asymptomatic patients according to skeletal pattern, gender, and age.

Objective: The aim of this study was to evaluate the prevalence of osteoarthritic alterations in the osseous components of the temporomandibular joint (TMJ) in asymptomatic patients with different skeletal patterns, gender, and age groups with cone beam computed tomography (CBCT) images.

Study Design: CBCT images of 213 asymptomatic patients were assessed for the presence of any degenerative changes in the condyle and fossa/eminence complex. Each TMJ was evaluated separately and was classified as normal, indeterminate for osteoarthritis, or affected by osteoarthritis.

Reliability and accuracy of linear measurements in cone-beam computed tomography using different software programs and voxel sizes.

Objectives: The aim of this study is to evaluate the accuracy of linear measurements on cone-beam computed tomography (CBCT) images using three software programs and different voxel sizes.

Methods: Ten human mandibles with 25 silica markers were scanned for 0.250-, 0.
