The complete elimination of bacteria inside the root canal is a difficult task, and inconsistent removal of the innermost layer of contaminated dentin leaves bacteria behind. PDT is an adjunct to conventional endodontic treatment due to its potential to reduce bacteria and its biocompatibility.
Report a case of endodontic treatment associated with Photodynamic Therapy (PDT).
STUDY DESIGN/PATIENT AND METHODS: A patient with chronic dentoalveolar abscess with radiolucent lesion next to the apexes of teeth 11 and 21 was submitted to conventional endodontic treatment associated with PDT. The canals were filled after two PDT sessions with an interval of 15days between applications.
After six months, total regression of apical periodontitis and no fistula or associated symptoms were observed.
The treatment proposed is a viable option for the clinician as it is easy to perform, has relatively low-cost and allows the improvement of symptoms in a short period of time.
彻底清除根管内的细菌是一项艰巨的任务，而对最内层受污染牙本质的清除不一致会导致细菌残留。由于光动力疗法（PDT）具有减少细菌的潜力及其生物相容性，它是传统牙髓治疗的辅助手段。
报告一例与光动力疗法（PDT）相关的牙髓治疗病例。
研究设计/患者与方法：一名患有慢性牙槽脓肿且在11和21号牙根尖旁有透射性病变的患者接受了与PDT相关的传统牙髓治疗。在两次PDT治疗后，间隔15天进行根管充填。
六个月后，根尖周炎完全消退，未观察到瘘管或相关症状。
所提出的治疗方法对临床医生来说是一个可行的选择，因为它操作简便、成本相对较低，并且能在短时间内改善症状。
