Teeth were manually sectioned longitudinally using a carborundum disk and examined under a light microscope (10× magnification) to assess enamel lamellae, enamel tufts, enamel spindles, interglobular dentin, the cementoenamel junction (CEJ), and incremental lines in cementum. Data were analyzed using the Chi-square (χ²) test to determine statistical significance.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Molars were the most examined teeth (37.0%), followed by premolars (25.5%), canines (22.5%), and incisors (15.0%).

Further, the cluster analysis with Cytohubba plug-in identified the <i>basic leucine zipper and W2 domains 1 (BZW1)</i> gene as a key target of miRNAs (hsa-let-7d-5p, hsa-miR-101-3p, and hsa-miR-15b-5p) in osteoblast cells.
