FAQ 常见问答题

Since the root of a human tooth is surrounded by alveolar bone, in the traditional root canal treatment, the doctor can hardly see the root canal structure, only by the X-ray film, can understand a little about the tooth root and root canal, the doctor can only judge and treat by hand. However, if the image of the medullary cavity and root canal structure can be enlarged, so that doctors can see the internal structure of the medullary cavity and root canal clearly and perform fine operations, the quality of root canal treatment can be significantly improved. Therefore, microscopic root canal therapy can be said to be the “devil in the details.
由于人的牙根是被牙槽骨所包绕的，在传统的根管治疗过程中，医生几乎不能看见根管内结构，仅仅凭借X线片，可稍稍了解牙根和根管的情况，医生只能凭手感进行判断和治疗；但如果能放大髓腔和根管结构的影像，使医生能够看清楚髓腔和根管内部的结构，精细操作，则可以明显提高了根管治疗的质量；所以，显微镜根管治疗可以说是“细节决定成败”的关键。

Clinically, some root canals have variation, calcification, hidden location, or small root canals, which makes them difficult to be detected by the naked eye. For example, in some failed cases of pulp plasticization treatment, there are more reddish-brown or dark brown plasticizers in pulp cavity and root canal, which increases the difficulty of root canal location. Or the affected tooth with a perforated root canal wall, which used to be repaired surgically or removed directly, but was locally enlarged through good lighting of the root canal microscope, so that the doctor could clearly identify and locate it, effectively increasing the success rate of treatment.
临床上有些根管存在变异，或钙化，或位置隐匿，或根管细小，导致肉眼难以察觉；比如一些做过牙髓塑化治疗的失败病例，由于髓腔和根管内，存在较多红褐色或深褐色的塑化剂，增加了根管口定位的难度；又或者是根管壁穿孔的患牙，以往使用外科方法修补或直接拔除，但通过根管显微镜的良好照明好局部放大，使医生可以清晰地辨别和定位，有效增加了治疗的成功率。

It is not necessarily necessary, generally after the microscope root canal treatment should be closed in time for filling treatment, and it is recommended to perform crown repair after surgery to prevent tooth fractures and prolong tooth life.
不一定的，一般显微镜根管治疗后要及时的封闭，进行补牙处理，建议术后行冠修复，防止牙齿折裂，延长牙齿的寿命。

When surgery is performed, local anesthesia is administered (some doctors may choose other forms of anesthesia); There may be mild postoperative pain, usually lasting 72 hours; But for the vast majority of patients, a painkiller can reduce the pain.
进行手术时，会行局部麻醉（一些医生可能选择其他形式的麻醉）；可能会有轻微的术后疼痛，一般持续72小时；但对于绝大多数患者来说，一片止痛药就可以减轻疼痛。

Microscopic root canal treatment, with the help of microscope and ultrasonic instruments, the Angle of the apical section and the tooth axis is controlled from the traditional 45 degrees to 0-10 degrees, thus effectively reducing the occurrence of apical microleakage.

显微镜根管治疗，在显微镜及超声器械的帮助下，根尖断面与牙体长轴的角度，从传统的45度控制到0-10度间，从而有效减少根尖微渗漏的发生。

Microscopic root canal therapy should be performed step by step according to the clinical examination of the patient; In general, root canal treatment requires about 2 visits.

显微镜根管治疗要根据患者临床检查情况，分步分次进行治疗；一般来说，根管治疗要约2次左右的就诊。
