Here we report the unusual case of a patient who suffered neurological deficit of the facial nerve as a complication of a root canal treatment. During the canal treatment, 3% hydrogen peroxide and 90% ethanol rinses were performed. The present case demonstrated rinse toxicity to vital tissue as evidenced by severe clinical damage. Chlorhexidine can be used instead of potentially toxic rinses with good antimicrobiological results. Furthermore, special attention should be paid to determination of the root canal length and the integrity of the canal system before rinsing. Also irrigation should be applied at a low pressure.
在此，我们报告一例不寻常的病例，该患者在根管治疗后出现面神经神经功能缺损这一并发症。在根管治疗期间，使用了3%过氧化氢和90%乙醇冲洗。本病例显示冲洗液对重要组织具有毒性，严重的临床损伤即为证据。氯己定可替代具有潜在毒性的冲洗液，且具有良好的抗菌效果。此外，在冲洗前应特别注意根管长度的测定以及根管系统的完整性。冲洗时也应采用低压冲洗。
