How mechanical stress can accelerate bone destruction in periodontitis

Article excerpt

Researchers found that excessive bite force alone doesn't destroy bone, but when combined with periodontitis, a gum disease, it dramatically accelerates bone loss. Using mouse models and gene expression analysis across periodontal tissues, scientists identified the inflammatory pathways that explain how mechanical stress amplifies the damage already caused by infection. The discovery fills a long-standing gap in understanding why traumatic occlusion worsens gum disease outcomes, potentially opening new treatment approaches that address both the infection and the biomechanical forces at work.
