Introduction:
Labial frenectomy is a common procedure in the oral surgery specialty. Nowadays, laser surgery seems to provide better post-operative results than scalpel surgery. Thus, the aim of this study was to analyze whether trans-surgical and postoperative variables of labial frenectomy are better when performed with laser than with conventional scalpel.
Materials And Methods:
A systematic review has been performed based on PRISMA criteria. The search included three databases, with no limitations of time or language. After screening, seven papers were included in qualitative analysis and six in meta-analysis. Bias analysis was performed according to Cochrane Handbook. Pain during the first (MD - 3.18, 95% CI - 4.03 to - 2.32) and seventh post-surgical days (MD - 1.04, 95% CI - 1.45 to - 0.64); discomfort during speech on the first (MD - 2.15, 95% CI - 3.94 to - 0.37) and the seventh post-surgical days (MD - 1.60, 95% CI - 1.96 to - 1.24); discomfort during chewing on the first (MD - 2.90, 95% CI - 3.35 to - 2.45) and the seventh days (MD - 1.56, 95% CI - 2.21 to - 0.91); and average surgery time (MD - 1.84, 95% CI - 3.22 to - 0.46) were lower in the laser group than in the scalpel group.
Conclusion:
The results of this systematic review have shown better results to laser group in the following variables: pain, discomfort during speech and chewing. However, the evidence is limited due the high risk of bias.
