破牙细胞在人乳牙根生理性吸收和炎性牙根内吸收等病理吸收中起非常重要的作用。其调控机制的研究尤其对理解机制尚不完全明确的炎性牙根内吸收有着重要的意义。本文综合新近文献中有关其调控机制及在牙根生理性及病理性吸收过程中作用机制的研究现状,阐述如下。一、破牙细胞与 Tooth cells in human deciduous root physiological absorption and inflammatory root resorption and other pathological absorption plays a very important role. The study of its regulation mechanism is of great significance especially for the absorption of inflammatory root, which is not yet fully understood. In this paper, the recent literatures about their regulatory mechanisms and the physiological and pathological effects of root resorption during the study of the status quo, described below. First, broken teeth cells and
