The golden standard of the treatment of radicular cysts is mainly root canal therapy or surgical excision with apicectomy. The root canals are usually disinfected by the mechanical and chemical actions of instruments and chemical irrigating solutions respectively. To improve the efficacy of the root canal disinfection process, many techniques have been used and many researchers are still trying to reach the quickest and most convenient way to achieve this goal. Diode lasers have shown antibacterial activity on dentinal tubules, and they can penetrate more than 1000 μm into the dentin. Our patient was a 25-year-old female with an infraorbital abscess caused by a non-vital maxillary canine with periapical radiolucency. After completing the conventional treatment, the optical fiber was inserted into the canal according to the working length previously measured. An 810 nm diode laser at the output power of 4 W was used to irradiate the root canals, with a 300 μm fiber. The patient was free of pain within a few days. The lesion was resolved in radiographic follow-ups, 3 and 6 months after the root canal treatment. A combination of conventional root canal therapy and an 810 nm diode laser is an effective treatment for non-vital teeth with periapical lesions.
根管囊肿治疗的金标准主要是根管治疗或根尖切除术联合手术切除。根管通常分别通过器械的机械作用和化学冲洗液的化学作用进行消毒。为了提高根管消毒过程的疗效，人们已经使用了许多技术，许多研究人员仍在努力寻找达到这一目标的最快、最便捷的方法。二极管激光已显示出对牙本质小管的抗菌活性，并且它们可以穿透牙本质超过1000μm。我们的患者是一名25岁女性，患有由一颗无活力的上颌尖牙伴根尖周透射区引起的眶下脓肿。在完成常规治疗后，将光纤根据先前测量的工作长度插入根管。使用输出功率为4W的810nm二极管激光，通过300μm的光纤照射根管。患者在几天内就不再疼痛。在根管治疗后3个月和6个月的影像学随访中，病变得到了解决。常规根管治疗与810nm二极管激光联合应用是治疗伴有根尖周病变的无活力牙齿的有效方法。
