Abstract：
Second molars are more susceptible to periodontitis when present adjacent to periodontally hopeless third molars. It is crucial to restore the health of the second molar and to prevent a dry socket after third molar extraction. To ensure complete eradication of infection along with regeneration, mere nonsurgical periodontal therapy might be inadequate. Thus, in this case report, high-level laser therapy (HLLT), advanced-platelet-rich fibrin (A-PRF), and low-level laser therapy (photobiomodulation [PBM]) were adapted to obtain a synergistic effect. HLLT was accomplished for decontamination and clot stabilization following the third molar extraction. Further, A-PRF was placed and irradiated with PBM on 3rd, 7th, 15th, and 21st days, postoperatively. There was reduced clinical probing depth and gain in clinical attachment level with a significant radiographic bone fill distal to second molar at 3 months follow-up. This combined use of HLLT, and PBM along with PRF could be a reliable treatment approach for regeneration, particularly in acute infections.
摘要：
当第二磨牙与牙周无望的第三磨牙相邻时，第二磨牙更容易患牙周炎。恢复第二磨牙的健康和防止第三磨牙拔除后的干燥窝至关重要。为了确保完全根除感染和再生，单纯的非手术牙周治疗可能是不够的.因此，在这个案例报告中,高水平激光治疗（HLLT），晚期富血小板纤维蛋白（A-PRF），和低水平激光治疗（光生物调节[PBM]）被调整以获得协同作用。在第三摩尔提取之后,实现HLLT用于净化和凝块稳定。Further,放置A-PRF并在3日用PBM照射，Seven,15th,第21天,术后。在3个月的随访中，第二磨牙远端的放射学骨填充明显，临床探查深度和临床附着水平降低。这种HLLT的结合使用，PBM和PRF可能是一种可靠的再生处理方法，特别是在急性感染中。
