Antimicrobial photodynamic therapy (aPDT) is an effective method for eradicating bacteria in periodontal therapy. Standard aPDT requires the insertion of a laser tip into a periodontal pocket, in which the direction of irradiation is limited. Therefore, we devised an aPDT method that uses a transgingival near-infrared wavelength and indocyanine green-encapsulated and chitosan-coated nanoparticles as a photosensitizer.

使用穿龈照射的抗菌光动力疗法抑制龈下细菌：一项随机临床试验

抗菌光动力疗法（aPDT）是牙周治疗中消灭细菌的有效方法。标准 aPDT 需要将激光尖端插入牙周袋，其中照射方向受到限制。因此，我们设计了一种 aPDT 方法，该方法使用穿龈近红外波长和吲哚菁绿封装的壳聚糖涂层纳米颗粒作为光敏剂。
