2016 Glossary - 56
pressure indicating paste n: a material injected or
spread on the intaglio surface of the denture to determine the pressure area on the supporting tissue of
a dental prosthesis.
pressure relief n: an obsolete term referring to the
alteration of the intaglio surface of the denture to
eliminate the pressure area of the denture-supporting tissue.
primary pain n: pain proximately associated with a
noxious stimulus versus referred pain, which is nonproximate.
probe n: a slender instrument, often calibrated, that is
used to explore or measure a wound, body cavity,
passage, or periodontal pocket.
probing depth n: the distance measured from an established reference point to the tip of the periodontal probe.
process n: (1) a bony projection or prominence; (2) any
technical procedure that involves multiple steps; (3)
the procedure to polymerize dental resin in the production of dental prostheses or bases.
processed denture base n: a heat polymerized, dense,
color-stable acrylic foundation that attaches to artificial teeth.
prodrome n: an early symptom indicating the onset of
a disease or condition.
profile n: an outline image of an object or structure as
viewed from the side.
profile record n: a record or registration of a patient
progenitor cell n: an undifferentiated cell that can differentiate into a specialized cell; also called a stem
prognathic n: a protruded position of the maxilla and/
or mandible in relation to the face;
prognathic adj: a forward relationship of the jaws, usually used with reference to the mandible.
prognathism n: the condition of a protruded position
of the maxilla and/or mandible in relation to the face.
progressive loading n: the gradual applications of
force on a dental implant either deliberately, as done
through a dental prosthesis, or inadvertently, from
forces placed by anatomic structures or parafunction.
progressive mandibular lateral translation n: the
lateral positional change of the mandible as the nonworking condyle translates along the articular eminence.
progressive systemic sclerosis n: a progressive autoimmune disorder resulting in overproduction of abnormal collagen leading to sclerosis and fibrosis of
the skin and internal organs. Oral structures become
stiff and indurated leading to a reduction of oral cavity access. The periodontal ligament spaces may appear enlarged on a radiograph. Also called systemic
projected pain n: the sensation of pain at an area remote from the site of origin.
prophylaxis, oral n: the art and science of preventing
gingivitis through the removal of bacterial plaque,
material alba, calculus, and extrinsic stain from the
teeth and roots performed by a dentist or hygienist.
Also called a prophy.
proportional limit n: the measurement of stresses that
is the point beyond which deformation is not directly
proportional to the load being applied.
proprioception n: the reception of sensory nerve terminal signals that provide information pertinent to
movements and the position of the body; awareness
mediated by signals from proprioceptors.
proprioceptor n: sensory nerve terminals that mediate signals related to movement and position of the
body and its parts.
prostaglandins n: a family of fatty acids, unsaturated
carboxylic acids, generated by arachidonic acid metabolism via the cyclooxygenase pathway. They are
produced by most cells and are potent regulators of
a number of biological processes. Their production is
inhibited by aspirin, ibuprofen, and other inhibitors
prosthesis (pl, prostheses) n: (1) a fabricated, artificial
replacement of a missing part of the human body; (2)
a device to improve or alter function of a damaged or
missing body part; (3) a device used to help achieve a
desired surgical outcome.
