EMG-guided Botox Injection Versus Conventional Botox Injection in Gummy Smile Patients

Sponsor: Cairo University

Summary

The goal of this clinical trial is to compare the effect of EMG-guided Botox injection with conventional Botox injection in Yonsei point, in patients with excessive gingival display. The main question it aims to answer is: • Does the use of electromyography (EMG) as a guide during Botox injection for patients with gummy smile has better effect than conventional injection in Yonsei point? Participants will be randomized in equal proportions between intervention and control groups. * Preoperative assessment of amount of gingival display, lip length (philtrum and vermilion length), and smile type. * For the intervention group, EMG readings will be done in Clinical Neurophysiology Department, Kasr Al-Ainy Hospital EMG-guided Botox injection (Intervention group). Conventional Botox injection in Yonsei point (Control group).
