Occlusal effects on text reading: an eye-tracker study.

Introduction: Asymmetric electromyographic (EMG) activity during teeth clenching has been linked to cognitive impairment, as evaluated by the Spinnler-Tognoni matrices test, and to asymmetric pupil size (anisocoria). Anisocoria indicates an asymmetric Locus Coeruleus activity, leading to an asymmetric hemispheric excitability worsening cognitive performance. Bite splint wearing corrects EMG asymmetry, reduces anisocoria and improves cognitive performance.

Trigeminal Stimulation and Visuospatial Performance: The Struggle between Chewing and Trigeminal Asymmetries.

Chewing improves visuospatial performance through locus coeruleus (LC) activation. The effects of bilateral and unilateral mastication were investigated in subjects showing different degrees of asymmetry in masseter electromyographic (EMG) activity during clenching and in pupil size at rest (anisocoria), which is a proxy of LC imbalance. Correlations between performance changes and asymmetry values were found in males, but not in females.

Inverted gracilis muscle free flap with intraoral vascular anastomoses for facial reanimation in vessel depleted neck: A case report.

The reinnervated gracilis muscle free flap represents a workhorse of facial reanimation. This procedure is carried out secondarily to parotid resections, due to advanced tumors that spread to the surrounding structures. Finding recipient vessels might be problematic if other reconstructive procedures are needed to address the defects.
