What this trial studies

This study examines how botulinum neurotoxin affects the jaw-neck envelope of motion in individuals who experience tooth wear due to bruxism. Participants will be randomly assigned to receive either the botulinum toxin or a placebo across three sessions, spaced 12 weeks apart. The researchers will measure the jaw-neck movement before the treatment and six months after the final intervention using advanced 3D optoelectronic recording systems to assess any changes.

Who should consider this trial

Good fit: Ideal candidates are individuals with tooth wear that has progressed into the dentin.

Not a fit: Patients with temporomandibular disorders or those on medications affecting the central nervous system may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new approach to managing tooth wear and bruxism symptoms.

How similar studies have performed: While the use of botulinum toxin for bruxism is explored in other studies, this specific approach focusing on the jaw-neck envelope of motion is relatively novel.
