Excessive gingival display can be treated with crown lengthening by scalpel, lasers, or electrosurgical equipment. This study aimed to evaluate the effects of crown lengthening, performed with diode laser or radiofrequency in terms of patient comfort and clinical outcomes.
19 patients with type 1A altered passive eruption in the maxillary anterior treated with diode laser (n = 11) or radiofrequency (n = 8) were included. A total of 114 teeth were analyzed. Patient-centered outcomes (post-operative bleeding, pain level, esthetic satisfaction) and clinical outcomes (swelling, gingival color, gingival margin stability) were evaluated at baseline and post-operative seven days, six weeks, and six months.
No significant differences were observed in terms of post-operative bleeding, pain, swelling, and gingival color at different time intervals between groups. In both groups, gingival margin change was significant from baseline to six weeks (p < 0.05); while it was non-significant between six weeks and six months, confirming the gingival margin stability (p > 0.05). In terms of esthetics, 17 patients were fully satisfied, with a higher proportion in the laser group.
A clinician can safely use both laser and radiofrequency in the treatment of excessive gingival display as both yield favorable clinical and patient-centered outcomes.
牙龈过度外露可通过手术刀、激光或电外科设备进行牙冠延长术治疗。本研究旨在评估二极管激光或射频进行牙冠延长术在患者舒适度和临床效果方面的作用。
纳入19例上颌前牙1A型被动萌出异常患者，其中11例采用二极管激光治疗，8例采用射频治疗。共分析114颗牙齿。在基线、术后7天、6周和6个月时评估以患者为中心的结局（术后出血、疼痛程度、美学满意度）和临床结局（肿胀、牙龈颜色、牙龈边缘稳定性）。
两组在不同时间间隔的术后出血、疼痛、肿胀和牙龈颜色方面均未观察到显著差异。两组中，从基线到6周牙龈边缘变化均显著（p<0.05）；而在6周和6个月之间无显著差异，证实了牙龈边缘的稳定性（p>0.05）。在美学方面，17例患者完全满意，激光组比例更高。
临床医生在治疗牙龈过度外露时可安全使用激光和射频，因为两者都能产生良好的临床效果和以患者为中心的结局。
