Oral Pathology
Acanthosis refers to the hyperplasia or
thickening of the stratum spinosum layer of the epidermis or epithelium. It is
often seen in conditions such as psoriasis or lichen planus. This is distinct
from other phenomena like increased mitotic division or disruption of the basal
lamina.

A permissive occlusal splint (also called a stabilization
splint or Michigan splint) is designed to: Allow the condyles to seat in the centric relation (CR)
position. Provide uniform posterior occlusion when the mandible is
in CR. Guide mandibular movements with anterior guidance,
ensuring posterior disocclusion during lateral and protrusive movements. This design "permits" the muscles and joints to function without
interference, reducing abnormal loading and parafunctional activity.

Periodontics
This process occurs due to the deposition of minerals, primarily calcium and
phosphate ions, in the presence of organic matrix components and bacteria within
the plaque.
Mineralization in dental plaque often starts at the interface between the tooth
surface and the plaque, where the organic matrix provides a substrate forthe
deposition of mineral ions.
As the process continues, the plaque can become increasingly calcified, with the
mineral content moving from the tooth surface outwards towards the surface of
the plaque.
This can lead to the formation oftartar or dental calculus, which is a hardened
deposit of mineralized plaque that can contribute to dental diseases like
gingivitis and periodontitis.

Oral PathologyMarcus Gunn phenomenon is characteristic of jaw winking syndrome, where there is synkinetic movement between the pterygoid muscles and the levator palpebrae superioris. This causes the eyelid to elevate when the jaw moves (especially with lateral jaw movements). This congenital condition involves aberrant neural connections. Marin-Amat syndrome, Horners syndrome, and Eagles syndrome do not involve this jaw-eyelid synkinesis.
