牙根吸收的原因与机制

The causes and mechanisms of root resorption

牙根吸收是正畸治疗中的常见并发症之一。牙根吸收的病因机制复杂,所必备的条件为损伤和刺激。牙根吸收活动中起主要作用的是与破骨细胞形态及生物学性质相似的破牙骨质细胞,承担主要破牙骨质功能。本文对各种牙根吸收的原因吸收机制进行综述,重点突出正畸性牙根吸收,以期对今后的基础研究和临床工作起一定的指导作用。

The movement of teeth during orthodontic treatment induces undesirable root resorption frequently.The factors and mechanisms of root resorption are complex.The cells responsible for dental tissue resorption are odontoclasts,which are similar to osteoclasts.This article presented a review of causes of different types root resorption and pathogenesis in orthodontically induced inflammatory root resorption（OIIRR）.
