根管清洁和成形是根管治疗成功的根本条件,若清理不彻底,根管内残存的碎屑有可能引起炎症、感染,导致治疗失败,而根管器械、超声预备、冲洗液、药物皆不能清除全部碎屑。新技术与传统方法相结合有可能提高清除根管内微生物和碎屑的能力。本文目的是评价氩激光辐射清除根管内碎屑的效能。 Root canal cleaning and shaping are the fundamental conditions for the success of root canal therapy. If the cleaning is incomplete, residual debris in the root canal may cause inflammation and infection, leading to failure of treatment. However, root canal equipment, ultrasonic preparation, irrigation fluid and drugs Can not clear all debris. The combination of new technologies and traditional methods has the potential to improve the ability to remove microorganisms and debris in the root canal. The purpose of this paper is to evaluate the effectiveness of Argon laser radiation in removing root canal debris.
