正畸学与牙髓学的关系,近来日益受到口腔医学界的重视。它们之间的关系包括两个方面:一是在病因方面,例如正畸治疗可能引起某些牙髓病,二是在治疗方面,例如牙髓治疗与正畸联合治疗。这种联合治疗是最近才作为一个重要的统一体提出来的,它不但能保存更多的牙齿,而且能使修复物更符合生理要求。一、病因方面:正畸治疗可以引起某些牙髓病,如牙根吸收、牙髓坏死等。因此,正畸医生在矫治过程中必须注意预防,一旦发生就需要及时治疗。(一)牙根吸收。牙根吸收是正畸治疗中最常见的副作用。Kerr认为:牙齿吸收是一种退行性变化,它可以从牙齿内部发生——内吸收,也可从牙体表面开始——外 The relationship between orthodontics and endodontics has recently received increasing attention from the stomatology community. The relationship between them includes two aspects: First, the etiology, such as orthodontic treatment may cause some pulp disease, the second is in the treatment, such as dental pulp and orthodontic treatment. This combination therapy was recently proposed as an important unity that not only preserves more teeth but also makes the restoration more physiologically responsive. First, the etiology: orthodontic treatment can cause some pulp disease, such as root resorption, pulp necrosis. Therefore, orthodontists in the correction process must pay attention to prevention, in the event of need for timely treatment. (A) root resorption. Root resorption is the most common side effect of orthodontic treatment. Kerr believes that tooth absorption is a degenerative change that can take place inside the teeth - internal absorption, but also from the surface of the tooth - outside
