牙髓塑化及根管充填目前仍采用手持光滑髓针插入根管上下捣动及旋转导入法，临床操作繁琐，效果且常不够满意。作者研制成功了牙髓塑化及根管充填导入器，临床应用取得了满意的效果。现介绍如下：1仪器构成分4部分（见图1）。（1）12V直流电源：由220V交流电经变压及整流。（2 Dental pulp plasticization and root canal filling are still using the hand-held smooth spinal needle inserted into the root canal up and down rotation and rotation into the method, the clinical operation is cumbersome, the effect is often not satisfactory enough. The authors successfully developed the dental pulp plasticizer and root canal filling introducer, and the clinical application has achieved satisfactory results. Now introduced as follows: 1 Instrument consists of 4 parts (see Figure 1). (1) 12V DC power supply: Transformed and rectified by 220V AC. (2
