The aim of this study was to evaluate the effects of photobiomodulation therapy (PBM) and ozone applications on patients' quality of life after gingivectomy and gingivoplasty. In this study, 36 patients with chronic inflammatory gingival enlargement underwent gingivectomy and gingivoplasty. The groups were randomly divided into control (n = 12), PBM (n = 12) and ozone (n = 12) groups. GaAlAs diode laser 810 nm wavelength at a non-contact and continuous mode with a power of 0.3 W and a density of 4 J/cm used for PBM for 1 min. Ozone was applied for 1 min for every 5 mm in contact mode at power level 9 using probe number 3. PBM and ozone applications were performed immediately after the operation, on the 3rd and 7th days. Pain assessment was performed at 3rd, 7th, 14th and 28th days after gingivectomy and gingivoplasty by using visual analogue scale (VAS). Oral Health Impact Profile (OHIP-14) records were obtained from the patients before gingivectomy and gingivoplasty and postoperative 7th and 14th days. OHIP-14 questions were also evaluated individually. VAS pain levels of the control group measured on the 3rd day were higher than the PBM group and on the 7th day were found to be significantly higher than both groups (p < 0.05). The total OHIP-14 score of the control group on the 7th postoperative day was found to be higher than the PBM group (p < 0.05). The mean score obtained from the third question of OHIP-14 at 7th and 14th day of the PBM group was found to be lower than the control and ozone groups (p < 0.05). The PBM and ozone applications after gingivectomy and gingivoplasty reduce the pain levels of patients and have a positive effect on patients' quality of life.
本研究旨在评估光生物调节疗法（PBM）和臭氧应用对牙龈切除术和牙龈成形术后患者生活质量的影响。本研究纳入 36 例患有慢性炎性牙龈肥大的患者，行牙龈切除术和牙龈成形术。将患者随机分为对照组（n=12）、PBM 组（n=12）和臭氧组（n=12）。使用波长 810nm 的 GaAlAs 二极管激光，以非接触、连续模式，功率 0.3W，密度 4J/cm2 进行 PBM，治疗 1 分钟。在接触模式下，功率水平为 9，每 5mm 探头 3 号应用臭氧 1 分钟。PBM 和臭氧应用于手术后立即进行，分别在第 3、7 天进行。在牙龈切除术和牙龈成形术后第 3、7、14 和 28 天，采用视觉模拟量表（VAS）评估疼痛。在牙龈切除术和牙龈成形术前、术后第 7 和第 14 天，从患者处获得口腔健康影响简表（OHIP-14）记录。还分别评估了 OHIP-14 问题。对照组在第 3 天测量的 VAS 疼痛水平高于 PBM 组，在第 7 天发现显著高于两组（p<0.05）。对照组在术后第 7 天的总 OHIP-14 评分高于 PBM 组（p<0.05）。在 PBM 组第 7 和第 14 天，OHIP-14 第 3 个问题的平均得分低于对照组和臭氧组（p<0.05）。牙龈切除术和牙龈成形术后应用 PBM 和臭氧可降低患者疼痛水平，并对患者生活质量产生积极影响。
