This describes the oculocardiac reflex (or a trigeminovagal response). Manipulation of the maxilla stimulates the trigeminal nerve (V), specifically the V2 division, which acts as the afferent limb. The efferent limb is the vagus nerve (X), leading to bradycardia.

Doppler imaging is useful for measuring the velocity and direction of blood flow, and identifying the location of stenosis. However, a monophasic (single-phase) tracing in a coronary artery typically indicates an abnormal, potentially stenotic, flow pattern, not a normal one. Normal coronary artery flow is biphasic or triphasic.

The condensation silicone impression materials are supplied as a base paste and a low-viscosity liquid catalyst (or a paste catalyst).
Putty is a high-viscosity material that has been developed in order to overcome the large polymerization shrinkage of the condensation silicone impression materials.
All the other impression materials are generally supplied as catalyst paste & base paste.

Alpha adrenergic agonists are used in combination with local anaesthetics to increase the concentration of LA at receptor site.

The amount of polymerization shrinkage in composite materials is directly related to the volume fraction of the polymer matrix; increasing the size and number of inorganic filler particles reduces the relative amount of polymer, thus decreasing overall shrinkage.
