根分叉形态通常出现在上颌磨牙、下颌磨牙和上颌双尖牙,也可出现在多根牙的前牙、尖牙和下颌前磨牙中。根分叉病变是指牙周炎的病变波及多根牙的根分叉区,在该处出现牙周袋、附着丧失和牙槽骨破坏,可继发于牙周炎、牙髓炎和根尖周的病变。由于磨牙根分叉部位解剖结构的复杂与多变,造成了该部位病变治疗的特异性,加之致病因素复杂,病变破坏程度不同,给临床治疗工作增加了一定难度。目前,根
Root bifurcation usually occurs in the maxillary molars, mandibular molars and maxillary bicuspids, also can appear in the multi-root anterior teeth, canines and mandibular premolar. Root bifurcation disease refers to the periodontitis lesions spread to the root of the root bifurcation of multiple teeth, there in the periodontal pocket, loss of attachment and alveolar bone destruction, may be secondary to periodontitis, pulpitis and root Peripheral lesions. Due to the complexity and variety of the anatomic structure of the molars root bifurcation, the specificity of lesion treatment in this site is caused. In addition, the complicated pathogenic factors and the different degrees of lesion damage add some difficulty to the clinical treatment. At the moment, root
