The aim of this study is to compare the conventional and diode laser techniques in terms of patient's perceptions, epithelization, reattachment, and periodontal clinical parameters in the treatment of abnormal papillary frenum. Forty-eight patients with abnormal papillary frenum were enrolled in the study. Patients were randomly assigned into three groups; conventional frenectomy operation (C group), diode laser-assisted frenectomy (L group), and diode laser-assisted frenectomy with conventional horizontal incision on the periosteum (L + P group). Postoperative pain, discomfort in speaking, and chewing scores were assessed with visual analogue scale (VAS) at postoperative 3rd hour and on days 1, 7, 14, 21, and 45. Epithelialization process of the wound surface was evaluated by hydrogen peroxide solution applied to the wound on days 7, 14, 21, and 45 following operations. The distance between the frenum attachment point and mucogingival junction (FMGJ) was recorded at baseline, postoperative 45th day, and 6th month to assess the reattachment of the frenum. Plaque index, gingival index, bleeding on probing, and probing depth were recorded at baseline and postoperative 7th, 14th, 21, and 45th days. On the 1st and 7th day after operation, VAS pain score in the C group was significantly higher than in the L and L + P groups ( < 0.017). Difficulty in speaking and chewing scores were significantly lower in the L and L + P groups compared to the C group at postoperative 3rd hour and 7th day ( < 0.017). The FMGJ and epithelization period demonstrated no difference among the groups at any time point ( > 0.05). Our results suggest that diode laser provides better postoperative patient's perceptions than the conventional technique in frenectomy operation. In addition, both conventional and laser-assisted frenectomy surgeries prevent the frenum reattachment regardless of periosteal horizontal incision.
本研究旨在比较传统和二极管激光技术在治疗异常纤维系带方面，从患者感知、上皮化、再附着和牙周临床参数方面的差异。本研究共纳入 48 例异常纤维系带患者。患者被随机分为三组：传统纤维系带切除术（C 组）、二极管激光辅助纤维系带切除术（L 组）和在骨膜上进行传统水平切口的二极管激光辅助纤维系带切除术（L+P 组）。术后第 3 小时及第 1、7、14、21 和 45 天，使用视觉模拟量表（VAS）评估术后疼痛、说话和咀嚼不适评分。术后第 7、14、21 和 45 天，用双氧水涂抹伤口评估伤口表面上皮化过程。记录基线、术后第 45 天和第 6 个月时纤维系带附着点与龈缘黏膜交界（FMGJ）之间的距离，以评估纤维系带的再附着情况。在基线、术后第 7、14、21 和 45 天记录菌斑指数、牙龈指数、探诊出血和探诊深度。术后第 1 天和第 7 天，C 组 VAS 疼痛评分明显高于 L 组和 L+P 组（<0.017）。术后第 3 小时和第 7 天，L 组和 L+P 组的说话和咀嚼困难评分明显低于 C 组（<0.017）。在任何时间点，FMGJ 和上皮化时间在组间均无差异（>0.05）。我们的结果表明，与传统技术相比，二极管激光在纤维系带切除术中提供了更好的术后患者感知。此外，传统和激光辅助纤维系带切除术均能防止纤维系带再附着，与骨膜水平切口无关。
