【摘要】：铒激光是一种硬组织激光,在应用过程中,大量的能量被照射区组织吸收,入射的能量几乎无残留,避免了能量的过度聚集,不会对照射区周围组织产生高温损害。根管清理和成形是根管治疗的重要步骤,用铒激光预备根管,根管壁上无涂层,牙本质小管开放。铒激光以及铒激光照射联合乙二胺四乙酸或次氯酸钠冲洗能更有效地去除根管壁的涂层,清洁根管,开放牙本质小管。细菌感染是根尖周病最主要的致病因素,铒激光以及铒激光与传统方法的联合,有很好的杀菌效果。当根管治疗失败时,根尖切除术是根尖周病治疗中常见的手术方法,铒激光根尖切除术后,切口断面光滑整洁、无碳化,组织创伤少,术后愈合好,根尖密闭性好。适宜的铒激光照射能量参数可避免对根尖周组织产生损伤,而且低能量的铒激光照射可为纤维干细胞的黏附提供很好的条件。
[Abstract]:Erbium laser is a kind of hard tissue laser. In the process of application, a large amount of energy is absorbed by the tissue in the irradiated area, and there is almost no residual incident energy, which avoids the excessive accumulation of energy and does not cause high temperature damage to the surrounding tissues of the irradiated area. Root canal cleaning and shaping is an important step in root canal therapy. The root canal is prepared by erbium laser. There is no coating on the root canal wall and the dentine canals are open. Erbium laser and erbium laser irradiation combined with ethylenediamine tetraacetic acid or sodium hypochlorite can effectively remove the coating of root canal wall, clean root canal and open dentin tubules. Bacterial infection is the main pathogenic factor of periapical disease. Erbium laser and the combination of erbium laser and traditional methods have good bactericidal effect. When root canal therapy fails, apical excision is a common method in periapical disease treatment. After erbium laser apical excision, incision section is smooth and neat, no carbonization, tissue injury is less, postoperative healing is good, and apical sealing is good. The proper energy parameters of erbium laser irradiation can avoid damage to periapical tissue, and low energy erbium laser irradiation can provide a good condition for the adhesion of fiber stem cells.
