Phleboliths of the Head and Neck Region - A Case Report.

Rationale: Phleboliths are idiopathic calcifications resulting from mineralised structures inside veins, venules or blood vessels.

Patient Concerns: A 48-year-old woman presented with multiple hard bodies on palpation.

Diagnosis: Imaging studies revealed multiple, round, well-defined radiopaque lesions, extending from the coronoid process region down to the base of the mandible.

Indices in dental image exams for bone mineral density evaluation of aromatase inhibitor users.

We evaluated the accuracy of radiomorphometric indices (RI) and fractal dimension (FD) for screening bone mineral density (BMD) in postmenopausal patients who had breast cancer and were using aromatase inhibitors (AI). The sample consisted of 40 participants. Digital panoramic radiography (DPR) and cone beam computed tomography (CBCT) were evaluated along with dual-energy X-ray absorptiometry (DXA), which is the gold standard for detecting low BMD.

New mandibular indices in cone beam computed tomography to identify low bone mineral density in postmenopausal women.

Objective: The aim of this study was to evaluate new radiomorphometric indices in cone beam computed tomography (CBCT) for assessing bone mineral density (BMD) status in postmenopausal women.

Study Design: Mandibular inferior cortical bone thickness was evaluated in 48 postmenopausal women in cross-sectional images at 4 sites: (1) symphysis (S): cross-sectional image equidistant from the centers of the right and left mental foramina (MF); (2) anterior (A): 10 mm anterior to the MF; (3) molar (M): 10 mm posterior to the MF; and (4) posterior (P): 25 mm posterior to the MF. Participants underwent dual-energy x-ray absorptiometry and were divided into normal, osteopenia, and osteoporosis groups.

Cone-beam computed tomography analysis of cemento-osseous dysplasia-induced changes in adjacent structures in a Brazilian population.

Objectives: To describe the effects of cemento-osseous dysplasia (COD) on anatomical structures.

Methods: CBCT scans were retrospectively selected from a database of individuals who attended an Oral Medicine service. Cases with a confirmed diagnosis of periapical, focal, or florid COD were included.

Mandibular radiomorphometric parameters of women with cemento-osseous dysplasia.

Objective: To compare the radiomorphometric parameters of mandibular trabecular and cortical bone of females with and without cemento-osseous dysplasia (COD).

Methods: A retrospective cross-sectional paired study was conducted. Digital panoramic radiographs were obtained from females diagnosed in a public service of Oral Medicine.

Use of fractal analysis in dental images: a systematic review.

Objectives: This study reviewed the use of fractal analysis (FA) in dental images.

Methods: A search was performed using PubMed, MEDLINE, LILACS, Web of Science and SCOPUS databases. The inclusion criteria were human studies in the English language, with no date restriction.

Digital panoramic radiography and cone-beam CT as ancillary tools to detect low bone mineral density in post-menopausal women.

Objectives: To evaluate the usefulness of the mandibular cortical index (MCI) obtained by digital panoramic radiography (DPR) and by panoramic reconstruction (PR) of cone-beam CT (CBCT) with three different slice thicknesses for the screening of low bone mineral density (BMD) in post-menopausal women.

Methods: Two trained oral and maxillofacial radiologists assessed the MCI based on the morphology of the mandibular bone cortex (classified as C1, C2 or C3). The DPR and PR of CBCT with slice thicknesses of 5, 15 or 25 mm were compared to the BMD obtained by dual-energy X-ray absorptiometry (DXA) in post-menopausal women.

Mandibular canal branching assessed with cone beam computed tomography.

Purpose: The mandibular canal must be considered in dental procedures to avoid injuries of the alveolar inferior nerve. The occurrence of anatomical variations of the mandibular canal increases the risk of neurovascular injuries. The purpose of this study was to identify and describe the prevalence of mandibular canal branching (MCB) using cone beam computer tomography (CBCT).

Radiographic and computed tomography monitoring of a fractured needle fragment in the mandibular branch.

Some complications can arise with the usage of local anesthesia for dental procedures, including the fracture of needles in the patient. This is a rare incident, usually caused by the patient's sudden movements during anesthetic block. Its complications are not common, but can include pain, trismus, inflammation in the region, difficulty in swallowing, and migration of the object, which is the least common but has the ability to cause more serious damage to the patient.
