Often in the treatment of Stomatology can be seen in the enclosed arsenic inactivation agent, because the patient did not timely referral reasons, causing arsenic apical.
In practice, with 20% of the iodine found in glycerol arsenic into the apical organization of periapical have a good effect. Than in 10 patients with iodine glycerin cotton twist better.
1. Treatment
Shall immediately remove inactivation agent, removal of the pulp through the root canal expansion, rinsing and drying the root canal. Then under local anesthesia, will have a good pumping 20g / L iodine glycerin 0.5 syringe needle, inserted into the root canal along the apical foramen near the narrow place, slowly push the injection, the iodine glycerin were slowly immersed in periapical destruction of arsenic the organization. The amount of visible pressurized injection into the resistance, are dental instruments generally injected 15-30S bell can. Then remove the syringe, in the root canal enclosed 30G / L iodine glycerin cotton twist, is the 3 days after the referral. The iodine glycerin cotton twist 1-2 times root canal dressing pain-free call, you can root canal filling.
2. Note
Before the injection of iodine glycerin, must extend through the root canal. This method is carried out under local anesthesia to avoid injection of iodine glycerin produces pain during and after injection. After injection of iodine glycerin, also enclosed in the root canal iodine Orthodontics pay attention to science glycerin cotton twist. An injection to prevent the liquid back to the immersion of periapical root canal, the second twist makes cotton on a small amount of iodine glycerin immersion apical tissue and increase efficacy.
3. Treatment
Within five years, 10 cases of apical arsenic patients, 8 patients after treatment, this method works well, follow-up observation without exception, the other 2 cases of root canal curvature can not expand through small, this method twice without success.
