Aim: This study aimed at assessing the degenerative changes in the Temporomandibular Joint (TMJ)in elderly patients with posterior edentulous maxilla and mandibula according to Cone-Beam Computed Tomography (CBCT) data. Materials and Methods: The study included 32 patients (64 temporomandibular joints) aged from 50 to 81 years (mean age 62 ± 7.9 years; 16 males and 16 females). TMJs were visualized on reconstructed parasagittal, paracoronal, and axial sections of the joint. The following changes in bone tissue were evaluated: condyle flattening, erosion, sclerosis, subchondral cysts, osteophytes. Joint space was evaluated as well. Results and Discussion: 100% of patients had at least one sign of degenerative changes in TMJ at least on one side. In 19 patients, degenerative symptoms were found only on one side. The most common sign was subchondral cysts. It was noted that the number of degenerative symptoms in male patients was statistically more than in the female group. On the right side, the anterior, superior, and posterior joint spaces had the following values: 2.35 mm, 2.95 mm, and 4.84 mm, respectively. On the left side, the anterior, superior, and posterior joint spaces had the following values: 2.14 mm, 2.3 mm, and 4.1 mm, respectively. Conclusion: Both edentulousness and aging affect the bone structure of TMJ in both genders.

Objectives: The effect of metallic objects on the fractal dimension (FD), bone area fraction (BAF) and gray scale values (GSVs) of cone-beam computed tomography (CBCT) images was assessed. Also, FD, BAF, and GSV were compared among CBCT, digital periapical, and panoramic radiographies. Methods: Digital periapical and panoramic radiographs were acquired from six blocks of bovine rib. Additionally, different arrangements of titanium implants and intracanal metallic posts were created in the bone blocks and CBCT scans were taken from the different implant-root arrangements. The three radiographic modalities were compared by analysis of variance. Pairwise comparisons between the modalities were performed by the Tukey test (significance level set at 0.05). Results: Different root- implant arrangements in the CBCT images revealed no significant differences in the FD (p = 0.920), BAF and GSV values (p = 0.623). FD differed significantly among the three modalities (p < 0.001). Significant differences were found between CBCT and each of the periapical and panoramic techniques (p < 0.001), while no remarkable differences were observed in the FD of the periapical and panoramic images (p = 0.294). BAF and GSV showed significantly different results among the three radiographic techniques (p < 0.001). The difference was remarkable between CBCT and periapical (p < 0.001), CBCT and panoramic (p < 0.001), and periapical and panoramic (p = 0.008). Conclusion: Presence of titanium implants and intracanal posts does not produce different results in the fractal analysis (FA) of the CBCT images. The trabecular bone pattern is best assessed by FA of the periapical radiographs followed by the panoramic and CBCT techniques, respectively.
