Recently, natural ingredients have focused on the inhibition of bacteria-induced alveolar bone resorption in orthodontic treatment. Jixueteng (Jix), a Chinese traditional medicine, contains several kinds of flavonoids given their biological properties. We evaluated the effects of Jix on experimental periodontitis during orthodontic tooth movement (OTM) in rats. To this end, 9-week-old male Wistar rats, which were equipped with orthodontic appliance, were orally infected with Porphyromonas gingivalis (Pg), while Jix was administered in their drinking water. A total of 28 days after the beginning of OTM, alveolar bone resorption on the right side of the upper jaws was scanned with micro-computed tomography. These were also used as histological specimens and underwent tartrate-resistant acid phosphatase (TRAP) staining. TRAP-positive multinucleated cells were counted as osteoclasts. As a result, the distance of tooth movement in the OTM and Pg infection with Jix administration (OTM + Pg + Jix) group was the same as that of the sham-infected group. The amount of bone resorption and number of osteoclasts in the OTM + Pg + Jix group was more significantly decreased than that in the OTM and Pg-infected group ( P < 0.05). Hence, Jix had little effect on OTM and inhibited Pg-induced alveolar bone destruction. We suggested that the administration of Jix can support tooth movement and contribute to the prevention of periodontitis during orthodontic treatment.
