Abstract

Objective: This current study aimed at investigating the effect of using Botulinum toxin A injection in gummy smile due to hyperactivity of the upper lip. Research subjects and Study design: Series of cases were observed on 15 patients of 18 years old with mean maximum gummy smile of 2mm from teeth 14 to 24 due to hyperactive upper lip muscles who came for examination and treatment at Ho Chi Minh City Hospital of Dermato-Venereology from 10/2022 to 07/2023. Botulinum toxin A injections were performed on multiple sites, with 2 U of each dose. Photos of the patients’ smiles were taken before and 2 weeks, 4 weeks, 6 weeks, 8 weeks after treatment. Results and Conclusions: The average dimensionof gingiva was 4.33 ± 1.01 mm at the beginning of the treatment and 1.16 ± 1.43 mm after 8 weeks. Treatment of gum exposure due to upper lip hyperactivity with Botulinum toxin A helps improve the patients’ smiles by giving to patients a standard, confident and attractive smile. Besides, it helps reduce pain pressure and treatment costs.
