Root resorption can be divided into two main categories: internal root resorption and external root resorption. Internal root resorption is a pathology that can lead to tooth destruction in the short term and must consequently be stopped as soon as possible by applying adequate canal treatment. Until now, despite many research studies, very little is known about its causes and the way this kind of resorption appears. There are many different forms of external root resorption and it has a very diverse etiology. An external root resorption can thus appear in case of orthodontic treatment or due to the pressure brought by cysts, tumours or impacted teeth. A trauma or an infection may also lead to the development of an external root resorption. Because they are so diverse, each of these forms of external root resorption requires a specific treatment. It should also be noted that internal root resorptions, and some forms of external resorption too, often respond favourably to a calcium hydroxide treatment.
内部牙根吸收和外部牙根吸收。内部牙根吸收是一种短期内可导致牙齿破坏的病变，因此必须通过进行适当的根管治疗尽快予以阻止。到目前为止，尽管有许多研究，但对其病因以及这种吸收出现的方式了解甚少。外部牙根吸收有许多不同的形式，其病因也非常多样。因此，正畸治疗、囊肿、肿瘤或阻生牙所带来的压力都可能导致外部牙根吸收。创伤或感染也可能导致外部牙根吸收的发生。由于这些外部牙根吸收的形式各不相同，每种形式都需要特定的治疗方法。还应注意的是，内部牙根吸收以及某些形式的外部牙根吸收，通常对氢氧化钙治疗反应良好。
