Abstract

Objective: Gummy smile (GS) also referred to an excessive gingival display (EGD). it’s an aesthetic disorder that can be managed by a variety of procedures include; modified lip reposition surgery (MLRS) and botulinum toxin type-A injection (BTX-A). This study aimed to evaluate and compare the effect of treatment of GS by surgical technique (MLRS) and non-surgical technique (BTX-A injection) 1 and 4 months after treatment. 

Methods: The study was conducted from November 2018 to November 2019. Forty adult patients aged 18-35 years with a EGD ≥ 4 mm caused by soft tissue disorders were recruited. Patients divided into two groups; Group 1 included 20 patients treated by MLRS and Group 2 (20 patients) treated by BTX-A injection. The amount of gingival display (GD) was evaluated after 1 and 4 months of the treatments by Autodesk AutoCAD computer program. ANOVA test used to compare changes in GD before and following treatments.

Results: The study showed a significant reduction in the amount of GD in both groups after 1 and 4 months of the treatment (p value < 0.05). Non-significant differences between both groups in 1 and 4 months of follow up (p value > 0.05).

Conclusions: Both MLRS and BTX-A injection technique were effective treatment modalities for patients suffering from GS.
