Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Ipsilesional Side Stimulated Occlusal Imbalance Group
In this group, occlusal imbalance will be induced by placing a cotton roll on the ipsilesional occlusal surfaces of the patients.
Ipsilesional Side Stimulated Occlusal Imbalance
In this group, a 1 cm thick cotton roll will be placed on the ipsilesional occlusal surfaces of the patients, and they will be instructed to hold it in place without clenching.
Contralesional Side Stimulated Occlusal Imbalance Group
In this group, occlusal imbalance will be induced by placing a cotton roll on the contralesional occlusal surfaces of the patients.
Contralesional Side Stimulated Occlusal Imbalance
In this group, a 1 cm thick cotton roll will be placed on the contralesional occlusal surfaces of the patients, and they will be instructed to hold it in place without clenching.
Bilateral Cotton Roll with Jaw Clenching Group
Patients in the bilateral cotton roll with jaw clenching group will clench their teeth while cotton rolls are placed on both sides of the occlusal surfaces.
Bilateral Cotton Roll with Jaw Clenching
In this group, a 1 cm thick cotton roll will be placed on both occlusal surfaces, and the patients will then be instructed to clench their teeth.
