Comparison of Effectiveness, Duration, and Patient's Satisfaction of Botulinum Toxin A and Hyaluronic Filler in the Treatment of Gummy Smile: An Study.

[AIM] This study aimed to compare the effectiveness, duration, and patient satisfaction of botulinum toxin A (BTX-A) and hyaluronic fillers in treating gummy smiles.

[MATERIALS AND METHOD] A prospective clinical study was conducted at D.Y. Patil University, involving 14 patients aged 18-40 years with a gummy smile of ≥3 mm. Participants were divided into two groups: Group A (BTX-A injections) and Group B (hyaluronic fillers). Gingival display was measured using standardized photographic methods at baseline and follow-up visits (14, 30, 60, and 90 days). Patient satisfaction was evaluated using the Global Aesthetic Improvement Scale (GAIS).

[RESULT] The results indicated that while BTX-A provided immediate improvements, hyaluronic fillers demonstrated more consistent and prolonged results. Patient satisfaction was higher in the hyaluronic filler group, with most patients reporting exceptional improvement (GAIS score of 1) across all follow-ups. No severe adverse effects were observed in either group.

[CONCLUSION] Hyaluronic fillers demonstrate superior effectiveness and patient satisfaction compared to BTX-A in the treatment of gummy smiles.
