The effects of technical factors on the fractal dimension in different dental radiographic images.

Purpose: The aim of this study was to assess the impact of exposure parameters and image formats on fractal dimension (FD) values in periapical, panoramic, and CBCT images.

Materials And Methods: Seven dry male mandibles were selected, and a Gutta-Percha was used to identify identical regions of interest. A periapical radiograph was taken with 60 kVp/7 mA and exported in DICOM, JPEG, TIFF, and PNG formats.

Effects of conventional complete dentures and implant-supported overdentures on alveolar ridge height and mandibular bone structure: 2-year and 6-year follow-up study.

Objectives: The aim of this study was to compare the changes in mandibular bone structure in edentulous patients who were rehabilitated with conventional complete dentures (CCD) and implant supported overdentures (ISO), by evaluating alveolar bone loss (ABL), panoramic mandibular index (PMI), mandibular cortical width (MCW), gonion index (GI), antegonial index (AI), and articular eminence inclination (AEI).

Materials And Methods: Panoramic radiographs of 63 edentulous patients using CCD, 63 edentulous patients using ISO, and 126 patients without tooth loss were evaluated. Edentulous patients had a 2-year and 6-year follow-up panoramic radiograph image.

Evaluation of chronic renal failure with cone beam computed tomography radiomorphometric indices and fractal analysis in the mandible.

Objectives: The purpose of this study is to evaluate the mandibular bone structure of patients with chronic renal failure (CRF) and compare to control group via the fractal analysis (FA) and radiomorphometric indices in the cone beam computed tomography (CBCT) images.

Methods: Three observers retrospectively investigated 44 CBCT images to compare patients with CRF to healthy controls. FA was performed in two different areas, volume of interests (VOI) were chosen in the mandibular ramus and corpus.

Fractal properties and radiomorphometric indices of the trabecular structure of the mandible in patients using systemic glucocorticoids.

Objectives: The aim of this study is to evaluate the mandibular trabecular and cortical bone structure of patients using systemic glucocorticoid (GC) and compare to control group with the fractal analysis (FA) and radiomorphometric indices.

Methods: Two researchers retrospectively investigated 192 dental panoramic radiographs to compare individuals using systemic GCs to healthy controls. FA was performed in 4 different regions; geometrical center of the mandibular ramus (ROI1), cancellous bone on supracortical mandibular angle area inferior to the mandibular canal (ROI2), cancellous bone on mesial to the mental foramen (ROI3), basal cortical bone extending mental foramen to the first molars' distal root in the mandibular corpus (ROI4).
