摘　　要：下颌髁突软骨(MCC)不同于生长板和身体其他部位的关节软骨,属于继发性纤维软骨,是颞下颌关节的重要组成部分。由于下颌骨附有牙齿行使咀嚼功能的特殊性,MCC在一生中受机械刺激影响不断改建,随年龄增长可能发生退行性变。甲状旁腺激素相关蛋白(PTHrP)最早在恶性体液性高钙血症中发现,在许多组织中以旁分泌或者自分泌的方式发挥调节骨代谢的作用,在MCC的发育、改建和退行性变中具有重要意义。本文就PTHrP在MCC中的作用进行阐述,为PTHrP在正畸功能矫形和颞下颌关节修复再生提供思路和研究方向。Mandibular condylar cartilage(MCC), different from other articular cartilages of the body, belongs to secondary fibrocartilage and is an important component of the temporomandibular joint. MCC constantly experiences reconstruction, responds to mechanical stimulation, and may degenerate with age due to the particularity of the mastication function of mandible with teeth. Parathyroid hormone-related protein(PTHrP), first discovered in malignant humoral hypercalcemia, regulates bone metabolism by paracrine or autocrine in many tissues. PTHrP plays a role in the development,remolding, and degeneration of MCC. This study reviews the research progress of PTHrP on MCC, which can provide new ideas for the research of PTHrP on the orthodontic functional treatment and repair and regeneration of the temporomandibular joint.
