* dental prosthesis: replacement of a missing part
of the natural dentition or oral cavity by an artificial device; fixed partial denture. See also denture
and removable partial denture.
* temporary prosthesis: a fixed or removable
restoration that is fabricated to be eventually replaced with a more permanent device.
prosthetic adj: concerning a prosthetics or a prosthesis.
prosthetically adv: concerning a prosthetics or a prosthesis.
protrusion n: (1) pertaining to mandibular jaw bone relationships-projection of the mandible anterior to
the position of centric relation; (2) pertaining to teeth
or jaw bones-projection of teeth or bony structures
anterior to the normal standard.
protrusive adj: forcing forward; adjective signifying
protrusion; the forward or thrusting movement of
the mandible.
protrusive deflection n: the displacement of the mandible from the midline during the protrusive movement of the mandible; the symptomatic restriction
of mandibular movement.
protrusive deviation n: the amount of protrusive
deflection during the protrusive movement of the
mandible. Protrusive deviation indicates interference during movement.
protrusive interocclusal record n: a registration of
the mandibular movement relative to the maxilla
during forward movement of the condyles in the
temporal fossa.
protrusive jaw relation n: an obsolete term referring
to the relationship of the mandible to the maxilla
that results from the protrusion of the mandible.
protrusive movement n: the movement of the mandible anterior to centric relation.
protrusive occlusion n: an obsolete term referring to
an occlusion that results when the mandible is advanced anterior to centric maximum intercuspation.
provisional cementation n: the cementation of an
interim or final restoration with a weak luting agent
such that the restoration can be easily removed at a
future date

provisional splint n: an interim device that stabilizes
mobile teeth during diagnostic or therapeutic procedures. Also known as an interim splint.
proximal adj: (1) nearest or adjacent to the reference
point; (2) situated near a point of origin, the midline
or attachment; (3) in dentistry the tooth surface adjacent to another tooth.
pseudomembrane n: a thin, adherent, gray-white exudative layer that forms over mucosa. It appears as a
false membrane and is composed of necrotic cells,
debris, and bacteria. Pseudomembranes are seen in
necrotizing ulcerative periodontitis.
pseudopocket n: a periodontal pocket that forms as a
result of tissue hypertrophy rather than as a result of
recession and apical migration of the junctional epithelium. See also periodontal intrabony pocket.
* pseudopocket space: the gingival crevice containing the periodontal ligament.
* pseudopocket syndrome: a collection of symptoms and clinical signs characteristic of periodontal diseases such as inflammation, loss of the gingiva, tooth mobility, etc.
* pseudopocket traumatism: see occlusal traumatism.
* suprabony pocket: a periodontal pocket with its
deepest point coronal to the alveolar bone.
psychophysical adj: a term referring to the relationship between physical stimuli and the sensory perception of the physical stimuli.
psychophysical color n: a measurement of color stimuli by scientifically defined values, such as 3 tri-stimulus coordinates.
pulp n: richly vascularized and innervated connective
tissue found at the inner core of a tooth called the
pulp cavity. The pulp is divided into the coronal aspect (coronal pulp) and root aspect (radicular pulp).
pulp capping v: the placement of a material or medicament to serve as a barrier to protect the pulp and
promote healing of the pulpal tissues. Pulp capping
is accomplished either directly or indirectly.
pulpectomy n: complete extirpation of the coronal
and radicular pulp.
