Deep periodontal pockets pose a great challenge for nonsurgical periodontal treatment. Scaling and root planing (SRP) alone may not suffice in cases where surgical therapy cannot be undertaken. Various recent studies have suggested the use of antimicrobial Photodynamic Therapy (aPDT) for the management of periodontal infections. The aim of this study was to evaluate the effects of using aPDT along with SRP, compared to SRP alone for the management of deep periodontal pockets. Thirty patients with chronic periodontitis, who met the criteria of having periodontal pockets with depth ≥ 6 mm and bleeding on probing (BOP) in at least 2 different quadrants were included. After SRP, one quadrant was randomly selected for aPDT (test), while another served as control. Clinical parameters i.e. plaque index (PI), modified sulcular bleeding index (mSBI), probing depth (PD) and clinical attachment level (CAL) were measured at baseline, 1 month and 3 months post-treatment intervals. All clinical parameters significantly improved in both groups after 1 and 3 months. At 1-month interval, inter-group difference in mean change was statistically significant ( < 0.05) in terms of mSBI (0.85 ± 0.41in test vs 0.54 ± 0.47 in control group) and PD (1.77±0.86 in test vs 1.3 ± 0.95 in control group). At 3 months interval, no statistically significant difference was observed between test and control groups except in terms of mSBI (0.97 ± 0.45 in test vs 0.73 ± 0.42 in control group). aPDT appears to play an additional role in reduction of gingival inflammation when used along with nonsurgical mechanical debridement of deep periodontal pockets.
深牙周袋对非手术牙周治疗构成了巨大挑战。在无法进行手术治疗的情况下，仅靠龈上洁治和根面平整（SRP）可能并不够。最近的各种研究表明，可使用抗菌光动力疗法（aPDT）来治疗牙周感染。本研究的目的是评估与单独使用SRP相比，联合使用aPDT和SRP治疗深牙周袋的效果。纳入了30例慢性牙周炎患者，这些患者符合至少2个不同象限存在深度≥6 mm的牙周袋且探诊出血（BOP）的标准。在进行SRP后，随机选择一个象限进行aPDT（试验组），另一个象限作为对照组。在基线、治疗后1个月和3个月时测量临床参数，即菌斑指数（PI）、改良龈沟出血指数（mSBI）、探诊深度（PD）和临床附着水平（CAL）。两组在治疗1个月和3个月后所有临床参数均有显著改善。在1个月时，试验组和对照组在mSBI（试验组为0.85±0.41，对照组为0.54±0.47）和PD（试验组为1.77±0.86，对照组为1.3±0.95）方面的组间平均变化差异具有统计学意义（<0.05）。在3个月时，试验组和对照组之间除了mSBI（试验组为0.97±0.45，对照组为0.73±0.42）外，未观察到统计学显著差异。与深牙周袋的非手术机械清创联合使用时，aPDT似乎在减轻牙龈炎症方面发挥了额外作用。
