The enteric nervous system is the intrinsic nervous system of the gastrointestinal tract and is responsible for the regulation of digestion and other gastrointestinal functions. It can operate independently of the central nervous system and consists of a network of neurons and glial cells that are embedded within the wall of the gut, coordinating local reflexes and influencing the muscle and secretory activities of the digestive system.

Tooth discoloration most commonly results from pulp necrosis. When pulp tissue dies: 1) Hemoglobin breaks down into iron sulfide and other dark pigments, 2) Protein degradation products penetrate dentin tubules, 3) These pigments become embedded in the tooth structure, 4) The discoloration progresses from pink to dark brown/gray over time. This is more common than hyperemia (which is reversible), pulpal abscess (which may not always cause visible discoloration), making pulp necrosis the primary cause of intrinsic tooth discoloration.

In orthodontics, wires with a low load deflection rate are typically preferred for areas requiring large tooth movements because they provide a more constant force as the tooth moves and the appliance is deactivated. This constant force is beneficial for controlling the rate of tooth movement.

Piezoelectric devices used in dentistry, such as for periodontal surgery or scaling, operate at high frequencies, typically in the ultrasonic range. The frequency range for these devices is generally between 30,000 Hz and 50,000 Hz (or 30 kHz to 50 kHz).

The IMViC test series is used to differentiate members of the Enterobacteriaceae family, including E. coli. E. coli typically has an indole positive (indole is produced when tryptophan is metabolized), methyl red positive (indicating the ability to ferment glucose and produce acid), Voges-Proskauer positive (produces acetoin from glucose), and citrate negative (does not utilize citrate as a sole carbon source) biochemical profile. This profile helps distinguish it from other related bacteria like Proteus and Klebsiella species.

A lingual arch is used as a bilateral space maintainer in the mandibular arch when there is bilateral loss of primary teeth.

It is a fixed appliance that maintains the arch length and circumference.
A distal shoe is a unilateral appliance used when a primary second molar is lost before the eruption of the permanent first molar.
A band and loop is also a unilateral appliance used for single tooth loss.

A band and bar is similar to a band and loop but with a more rigid bar.
