Cone-Beam Computed Tomography Evaluation of the Mandibular Condyle and Articular Spaces Following Orthognathic Surgery Using Freehand Articulation Method in Patients With Class II and III Skeletal Deformity.

This study aimed to assess the changes in the position and size of articular spaces and anteroposterior and mediolateral condyle dimensions following orthognathic surgery. Additionally, it evaluated the correlation between these changes and mandibular movement during surgery. This experimental study examined 31 patients (16 with Class III and 15 with Class II malocclusions) who were candidates for orthognathic surgery.

Age-related variations in physical activity, happiness, and psychological well-being: Evidence from Iran.

Background: Physical activity (PA) is associated with higher levels of PWB and happiness. The high prevalence of physical inactivity among the Iranian population is concerning. Moreover, according to the Happiness Report 2024, Iran is ranked 100th out of 143 countries.

Polyphenol autoxidation and prooxidative activity induce protein oxidation and protein-polyphenol adduct formation in model systems.

Polyphenols are well-known for their antioxidant properties, but their prooxidative activity remain less understood. This study quantitatively examined the formation of hydrogen peroxide (HO) during the autooxidation of nine different polyphenols in model systems, investigating how it impacts protein oxidation and protein-polyphenol covalent adduct formation. Polyphenols (4 mM) generated HO in the range of 0.

Odontogenic carcinosarcoma of the mandible: A case report.

Key Clinical Message: Odontogenic carcinosarcoma, a rare and challenging diagnosis, was identified in a 60-year-old male through histopathology, revealing a biphasic neoplasm with malignant epithelial and mesenchymal components. Surgical resection is crucial for management, highlighting the importance of vigilant postoperative follow-up to ensure early detection of any recurrence.

Abstract: One rare mixed malignant odontogenic tumor is odontogenic carcinosarcoma, which comprises malignant epithelial and mesenchymal components.
