Visceral pain
Deep somatic pain that results from the activation of nociceptors of the mucosal linings, walls of hollow viscera, parenchyma of organs, glands, dental pulps, and vascular structures. These visceral structures may not respond to stimuli that normally evoke pain, such as cutting or burning are sensitive to distension (stretch), ischemia, and inflammation. Pain caused by…

Virus
One of a group of minute (15–300 nm) infectious agents characterized by a lack of independent metabolism and the ability to replicate only within living cells. Submicroscopic organism that causes infectious disease. In cancer therapy, some viruses may be made into vaccines that help the body build an immune response to, and kill, tumor cells.…

Virulence
The disease‐producing potential of a microorganism. Often defined in terms of virulence factors, which are specific characteristics or abilities of the microorganism. The degree of pathogenicity within a group or species of microorganisms or viruses as indicated by case fatality rates and/or the ability of the organism to invade the tissues of the host. The…

Virtual surgical planning
Presurgical manipulation of 3D models of the surgical site to predict outcomes, design surgical guides, or develop options. Generally limited to surgery involving movement of bone, specifically in craniofacial, orthopedic surgery, dental implant placement, and heart and other soft tissue surgical planning.

Virtual reality modeling language (VRML)
Text file format where, for example, vertices and edges for a 3D polygon can be specified along with the surface color, UVmapped textures, shininess, transparency, etc.

Virtual reality (VR)
A term that applies to computer‐simulated environments that can simulate a physical presence in places in the real world, as well as in imaginary worlds. Most current VR environments are primarily visual experiences, displayed either on a computer screen or through special stereoscopic displays. Some simulations include additional sensory information, such as sound through speakers…

Virtual model
Digital 3D representation of a dental model created from an intraoral or desktop scan of an object.

Virtual articulation
The process of simulating static and dynamic relationship of teeth in opposite arches using computer software.

Virology
The study of viruses – biosystems that require a host to replicate, are capable of being pathogenic and can be classified according to their nucleic acid genome (DNA or RNA). The science that deals with the study of viruses. The study of viruses under the headings of: (1) human and animal diseases; (2) bacteriophages; (3)…

Vincent’s angina
Painful membranous ulceration of the oropharynx, throat, or gums that may be caused by Fusobacterium nucleatum infection. It is usually associated with necrotizing ulcerative periodontitis and referred to as trench mouth. Putrefactive infection of the tonsils, oral cavity and gums, caused by the joint action of Borrelia vincentii and Fusobacterium fusiforme—an example of bacteriological symbiosis.…
