dc.description.abstract | Aims: To elucidate the effects of decreased occlusal loading (DOL), with or without reloading (RL), on the structure and bite force function of the mandibular condylar fibrocartilage in skeletally mature male mice.Methods: At 13 weeks old, 30 wild type (WT) male mice were subjected to: (1) 6 weeks normal loading (NL); (2) 6 weeks DOL; or (3) 4 weeks DOL + 2 weeks RL. Histomorphometry, cell metabolic activity, gene expression of chondrogenic markers, and bite force tests were performed.Results: DOL resulted in a significant increase in apoptosis (P < .0001) and significant decreases in fibrocartilage thickness (P < .05) and hypertrophic chondrocyte markers indian hedgehog and collagen type X (P < .05). A corresponding decrease in bite force was also observed (P < .05). RL treatment resulted in a return to values comparable to NL of chondrogenic maturation markers (P > .10), apoptosis (P > .999), and bite force (P > .90), but not in mandibular condylar fibrocartilage thickness (P > .05).Conclusions: DOL in skeletally mature mice induces mandibular condylar fibrocartilage atrophy at the hypertrophic cell layer with a corresponding decrease in bite force. | en_US |
