所谓根分歧部病变,乃是一种边缘性牙周病变。由于多根牙的解剖学上的特殊性,其早期症状较难确诊,处理时困难也不少。因而,根分歧部病变及其处理,是牙周治疗学方面的重要部份。根分歧部病变的原因及其特殊性引起根分歧部病变的原因,通常有以下四方面:一,由局部原因所致的边缘性炎症,沿根面波及多根牙分歧部,结果引起该部发生和单根牙的破坏本质上相同的病变。二,创伤性咬(牙合)引起,多根牙所在的支持组 The so-called root branch disease, but a marginal periodontal disease. Due to the anatomical specificity of multiple teeth, the early symptoms are more difficult to diagnose and there are many difficulties in handling. Thus, the root branch disease and its treatment, is an important part of periodontal therapy. The root causes of branching lesions and their particularities Root causes of branching lesions, usually in the following four aspects: First, the marginal inflammation caused by the local causes, along the root surface of multiple teeth and spread to the Ministry of the Ministry of the Department Lesions that are essentially the same as the destruction of a single tooth occur.
