MAC is a measure of potency; lower MAC indicates higher potency. A MAC value over 100% (like 105% for N2O) indicates that it is a very weak anesthetic, requiring a theoretical concentration higher than atmospheric limits to achieve anesthesia in 50% of patients.

Oral Pathology
Periapical granulomas were diagnosed as well-circumscribed periapical
radiolucency measuring less than 1.5 cm in diameter, periapical cysts were
characterized by well-defined periapical radiolucency with sclerotic borders
measuring greater than 1.5 cm, and periapical abscesses were characterized by
ill-defined periapical radiolucency with diffuse margins. While bone resorption can occur in the presence of a periapical granuloma, it
is not a prerequisite for its formation. A periapical granuloma can develop in
response to pulp necrosis or infection without necessarily requiring bone
resorption to occur first. The granuloma can form as a reaction to the
inflammatory process, regardless of the state of the surrounding bone.

Extraction in irradiated bone carries a high risk of Osteoradionecrosis (ORN). RCT is preferred to manage the infection without surgical trauma to the bone.

ProsthodonticsThe main drawback of metallic denture bases in distal extension situations is that they cannot be easily relined when ridge resorption occurs. Metal bases require complex laboratory procedures for relining, unlike resin bases which can be chairside relined. This limitation makes adjustment to tissue changes difficult and expensive.

Epithelial cells migrate rapidly to the root surface and form a new epithelial attachment via hemidesmosomes within approximately one week following periodontal surgery.

Hysteresis in dental gels refers to the temperature lag or difference between the gelation temperature and the temperature at which the gel reverts back to a liquid state.

PhysiologyThe osmolarity of the tubular fluid leaving the early distal tubule is hypotonic, as it has lost solutes while retaining water.
