Article Synopsis
- - In oral squamous cell carcinoma (OSCC), macrophages, especially those with an M2-like phenotype, play a significant role in the tumor microenvironment and are associated with poorer patient outcomes.
- - This study examines how transforming growth factor beta (TGF-β), secreted by OSCC cells, influences macrophage behavior and their role in tumor invasion by testing various inhibition strategies in lab settings.
- - Results showed that blocking TGF-β signaling altered macrophages toward a more inflammatory (M1) phenotype and decreased the tumor invasion capabilities of specific OSCC cell lines, highlighting the complex interaction between tumors and immune cells.
Objective: To evaluate the diagnostic efficacy of the combined assessment of the original radiographic image with the Invert or Emboss digital enhancement filters in periapical radiographs obtained with different horizontal projection angles in the detection of simulated dental root fracture.
Materials And Methods: Thirty-four single-rooted teeth were selected, out of which 17 teeth were subjected to root fracture. Each tooth was individually placed in an empty socket of a dry human maxilla or mandible and X-rayed following the paralleling technique at three horizontal projections: mesial, right angle, distal.
