Objectives: The aim of the present study was to compare cone-beam computerized tomography (CBCT) findings and joint space measurement in temporomandibular disorder (TMD) and non-TMD joints, and to correlate these findings with the clinical diagnosis.
Methods: The study was conducted on patients diagnosed with temporomandibular joint (TMJ) osteoarthritis or closed lock according to the Research Diagnostic Criteria for TMDs (Group IIb, IIc, and III). CBCT and clinical records of non-TMD patients who sought treatment for purposes other than TMD were used retrospectively as a control. The following radiographic criteria were assessed: flattening, osteophyte, Ely's cyst, condylar surface irregularities, and joints' space measurements.
Results: Osteoarthritic joints had significantly more condylar irregularities (P50.0), osteophytes (P50.0), and condylar flattening (P50.003) than non-TMD joints. Osteoarthritic joints had significantlymore superior surface irregularities (P50.0) and osteophytes (P50.006) than closed lock joints.Non-TMDjoints had significantlymore joint space (5.64+1.88) compared with osteoarthritic joints (4.57+1.97), (P50.025). The correlation among TMD, osteophytes, and flattening of the condylar surface was statistically significant (r50.331, Pv0.000).
Discussion: Cone-beam computerized tomography findings are significantly associated with the clinical diagnosis of TMD. Osteophytes and flattening of the condylar surface are common features of TMD.

This study aimed to investigate the computed tomography (CT) values and morphology of the temporomandibular joint (TMJ), specifically the condyle and glenoid fossa, in female patients with jaw deformities before and after orthognathic surgery. The maximum CT values were measured on the condylar and glenoid fossa surfaces. In addition, the height, length, and area of the glenoid fossa in the sagittal plane were evaluated for the bilateral TMJs, preoperatively and one year postoperatively.

Background: Bicondylar tibial plateau fractures are often associated with significant soft tissue compromise making operative treatment challenging. Dual plating through a two-incision approach following temporary external fixation has been shown to improve complication rates although deep infection rates remain high.The objective was to evaluate early outcomes following a novel technique of percutaneous application of the medial plate superficial to the pes anserinus tendons.

Introduction The role of the condylar position in the correct functioning of the stomatognathic system has been the center of the study. Using cone-beam computed tomography (CBCT), this study looked at the three-dimensional (3D) position of the condylar bone in patients from Class I, Class II, Division 1, and Division 2. Materials and methods This cross-sectional, retrospective study was conducted using 102 CBCT records, with 34 records allocated to each category of malocclusion classification, such as dentoskeletal Class I, skeletal Class II, and dental Class II, Division 1 and 2.

Background: Studies have revealed abnormalities of the epiphyseal plate of the distal femur in patients with trochlear dysplasia, but it is unclear whether the epiphyseal plate could be remodeled after surgical correction of patellar dislocation.
Purpose: To investigate whether the morphology of the epiphyseal plate and trochlea could be improved after medial patellar retinaculum plasty in skeletally immature patients and to investigate the correlations between the morphology of the epiphyseal plate and trochlear dysplasia as well as clinical outcomes.
Study Design: Cohort study; Level of evidence, 3.
