The Protective Effects of β-Cryptoxanthin on Inflammatory Bone Resorption in a Mouse Experimental Model of Periodontitis

We examined the effects of β-cryptoxanthin, a typical carotenoid, on inflammatory periodontitis. β-Cryptoxanthin suppressed lipopolysaccharide (LPS)-induced osteoclast formation in co-cultures of bone marrow cells and osteoblasts. In a mouse model of periodontitis, it suppressed bone resorption in the mandibular alveolar bone in vitro and restored alveolar bone loss induced by LPS in vivo. β-Cryptoxanthin might protect against periodontal disease.
