Gummy smile (GS) is a nonesthetic condition that affects the confidence of many young people. The present study aimed to compare the results of two approaches used in the management of GS in a group of Egyptian females.
This comparative cohort study included 24 female patients aged 25-35 years, divided into two groups. Group A included patients treated with diode dental laser gingivectomy, while Group B included patients who were treated with Botox injection. The clinical assessment of the pre-and post-operative measurements of exposed gums in millimetres on an active full smile was analyzed and compared for both groups. The paired -test was used to compare pre and post measurements in each group, and the mean difference between the groups was compared using the independent -test.
Group A showed instant improvement, while Group B results appeared 1 week later. The variation between preoperative and postoperative GS measurements in both groups was statistically significant. The preoperative and postoperative mean ± standard deviation was (5.17 ± 0.9 and 1.89 ± 0.5) in Group A and (4.27 ± 1.0 and 1.79 ± 1.0) in Group B. Comparison between the two groups revealed a highly significant greater mean difference of 3.27 ± 0.5 mm in Group A than Group B ( < 0.001). The findings were satisfactory in all cases of both approaches, and there were no complications.
Using a diode laser to treat gummy smiles for oro-dental genetics case with gingival hypertrophy saves time and effort compared to conventional surgical techniques. Diode dental laser is a safe fast and effective method of treatment giving more superior results than Botox injection which showed a less invasive alternative temporary GS therapy that is easily guaranteed and more patient-favored.
露龈笑（GS）是一种影响许多年轻人自信心的非美观状况。本研究旨在比较在一组埃及女性中用于治疗露龈笑的两种方法的效果。
这项比较队列研究纳入了24名年龄在25至35岁之间的女性患者，分为两组。A组包括接受二极管牙科激光牙龈切除术治疗的患者，而B组包括接受肉毒杆菌毒素注射治疗的患者。对两组患者在主动全口微笑时以毫米为单位的术前和术后牙龈暴露量进行临床评估并分析比较。采用配对t检验比较每组术前和术后的测量值，并使用独立t检验比较两组之间的平均差异。
A组显示出即时改善，而B组的效果在1周后出现。两组术前和术后露龈笑测量值的差异具有统计学意义。A组术前和术后的平均±标准差为（5.17±0.9和1.89±0.5），B组为（4.27±1.0和1.79±1.0）。两组之间的比较显示，A组的平均差异比B组高3.27±0.5毫米，差异极显著（P<0.001）。两种方法的所有病例结果均令人满意，且无并发症。
与传统手术技术相比，使用二极管激光治疗因口腔牙齿遗传学病例伴牙龈肥大导致的露龈笑省时省力。二极管牙科激光是一种安全、快速且有效的治疗方法，其效果优于肉毒杆菌毒素注射，后者是一种侵入性较小的替代性临时露龈笑治疗方法，易于实施且更受患者青睐。
