Abstract
The effectiveness of therapeutic ultrasound in managing Grade II and III oral submucous fibrosis is of interest. Sixty patients were divided into three groups: ultrasound therapy alone, active physiotherapy alone and a combination of both. Patients were assessed for burning sensation, maximum mouth opening, and cheek flexibility. Statistical analysis (p<0.05) confirmed that combination therapy provided the most significant improvement. The findings suggest that ultrasound therapy combined with active physiotherapy, specifically jaw-opening exercises, is the most effective treatment modality for oral submucous fibrosis.
