作者用“CCQ”材料作根管充填,并随访观察了年龄在9～70岁之间的病员,共304个根管充填的疗效。结果表明,成功率为98.7%。CCQ 牙髓治疗剂对根尖周组织无不良刺激,促进根尖周病变的愈合较快,超填后能被吸收,少量欠填对疗效未见明显影响。此材料流动性好,容易输入根管,对 X 射线阻射,并且不使牙齿变色。必要时能较易地用根管扩大针取出。作者经过2年半的观察,根管内的充填材料未见吸收。 The author used “CCQ” material for root canal filling, and followed up to observe the age of 9 to 70 years old patients, a total of 304 root canal filling effect. The result shows that the success rate is 98.7%. CCQ endodontic treatment agent on the periapical tissue without adverse stimuli and promote faster periapical lesions heal, can be absorbed after overfilling, a small amount of underfill no significant effect on the treatment. This material is fluid, easy to enter into the root canal, blocks X-rays and does not discolor the teeth. When necessary, can be easier to use the root canal to expand the needle out. After 2 and a half years of observation, there was no absorption in the filling material in the root canal.
