1985～1988年,我科用塑化剂充填根管治疗根尖周炎共100例,并进行了随访,现将结果报告如下。 1.塑化治疗的技术操作常规开髓:除去髓室顶及髓室内容物,清洗窝洞,并扩大根管,用1～3号根管钻离根尖约2～3mm,拭干髓室用器械将液体逐渐送入髓室(上颌牙可用带有弯针头的注射器,头部后仰),并以根管钻导入根管离根尖约2～3 mm,用棉球将液体吸去,再送入液体,导入根管后再吸出,如此反复3～4次,最后一次,不能将液体吸出。以丁香油粘固粉与液体剂调拌成千糊剂,用蘸有液体的棉球将糊剂铺于髓室底。拭净窝洞上层多余溢出的液体,垫锌水门汀基底,银汞充填,这是一次法。二次法是在清理扩大根管后,封药消毒(多用甲醛甲酚合剂),复诊时液体充填。急性尖周炎俟病情消退后,再按二次法。液充
From 1985 to 1988, 100 cases of periapical periodontitis were treated with plasticizer and root canal filling, and were followed up. The results are reported as follows. 1. plasticization of the technical operation of the conventional open pulp: remove the pulp chamber and the contents of the pulp chamber, clean the nest hole and expand the root canal, with 1 to 3 root canal drilling apical about 2 ~ 3mm, dry the pulp Room equipment will be gradually liquid into the pulp chamber (maxillary teeth can be used syringe with a curved head, the head backwards), and root canal into the root canal from the apical root about 2 ~ 3mm, with a cotton ball to liquid absorption Go, and then into the liquid into the root canal and then sucked out, so repeated 3 to 4 times, the last time, can not be aspirated liquid. Clove oil with liquid agent to mix into a thousand paste, with a cotton ball dipped in liquid paste shop in the pulp chamber at the end. Wipe the upper hole overflow hole excess liquid, pad zinc cement base, amalgam fill, this is a law. The second method is to expand the root canal after cleaning, sealing drug disinfection (with formaldehyde cresol mixture), referral liquid filling. Acute periapical disease 俟 illness subsided, press the second method. Liquid filling
