Brooks Flashcards
ABFRACTION
The hypothetical process leading to the loss of cervical tooth structure due to a combination of abrasion, erosion, and/or occlusal forces; data supporting this term as a discrete clinical entity are equivocal. See also ABRASION and EROSION
ABRASION
The wearing away of tooth structure or restorative material through an abnormal mechanical process. Examples include gingival and dental abrasions due to incorrect brushing.
ABSCESS
Localized collection of purulent exudate (pus) in a cavity formed by the disintegration of tissues due to an infectious process or foreign material.
ACUTE ABSCESS
Abscess of rapid onset, typically producing pain and local inflammation.
APICAL ABSCESS
Inflammatory condition characterized by formation of purulent exudate involving the dental pulp or pulpal remnants and the tissues surrounding the apex of a tooth.
CHRONIC ABSCESS
- Abscess of comparatively slow development with little evidence of inflammation. There may be an intermittent discharge of purulent matter. 2. Long-standing collection of purulent exudate. It may follow an acute abscess. See also RESIDUAL ABSCESS
GINGIVAL ABSCESS
A localized purulent infection that involves the marginal gingiva or interdental papilla.
PERICORONAL ABSCESS
A localized purulent infection within the tissue surrounding the crown of a partially erupted tooth.
PERIODONTAL ABSCESS
Localized purulent collection in the periodontal tissues; also called lateral periodontal abscess.
PULPAL ABSCESS
Inflammation of the dental pulp characterized by the formation of purulent exudate.
RESIDUAL ABSCESS
Persistent abscess formed by the residues of a previous infection or foreign material.
ABSORPTION
- Passage of a substance into the interior of another substance. 2. Passage of fluids or substances through tissues. 3. Attenuation of radiation energy by the substance through which it passes.
ABUTMENT
Tooth, root, or implant used to support and/or retain a fixed or removable prosthesis.
ACANTHOLYSIS
Dissolution of the intercellular attachments within the prickle cell layer (stratum spinosum) of stratified squamous epithelium. Classically seen in pemphigus vulgaris during vesicle and bulla formation.
ACANTHOSIS
Hyperplasia of the prickle cell layer (stratum spinosum) of stratified squamous epithelium, resulting in thickened rete ridges or widening of this layer.
ACCRETION
Accumulation on the teeth of foreign materials such as plaque, materia alba, and calculus.
ACELLULAR
Substance that is devoid of cells.
ACELLULAR DERMAL MATRIX
An allogenic collagen material that has been treated to remove all cells to provide a matrix to support tissue regeneration and re-vascularization ultimately being transformed into host tissue. Indicated in mucogingival/regenerative procedures.
ACHE
Any dull, continuous or throbing pain. It is a subjective sensation, thought to be the psychological manifestation of c-fiber (slow, nonmyelinated) nociceptive impulses with origin outside the central nervous system.
ACQUIRED
Not congenital, but attained after birth. Examples include acquired immunodeficiency syndrome, acquired immunity and acquired reflexes.
ACTINOMYCES ISRAELII
A gram-positive, non-motile, facultatively anaerobic, pleomorphic bacterium. It is commonly found in the soil but can also be found in dental plaque and the intestinal tract of mammals. It is typically a commensal bacterium but is the most common actinomyces species found in the opportunistic infection actinomycosis.
ACTINOMYCES NAESLUNDII
A gram-positive, non-motile, facultatively anaerobic, pleomorphic bacterium found in marginal and interproximal plaque of healthy individuals. Cell morphology is often curved or branching rods. An early colonizer of the tooth surface and generally associated with oral health, however along with other Actinomyces species, it is associated with acid production and root caries, and may be found in elevated numbers in periodontal diseases.
ACTINOMYCES VISCOSUS
A gram-positive, non-motile, facultatively anaerobic, pleomorphic bacterium found in marginal and interproximal plaque of healthy individuals. Cell morphology is often curved or branching rods. An early colonizer of the tooth surface and generally associated with oral health, however along with other Actinomyces species, it is associated with acid production and root caries, and may be found in elevated numbers in periodontal diseases.
ACUTE
- Sharp, severe. 2. Denoting the swift onset and course of a disease.
ACYCLOVIR
A synthetic acyclic purine nucleoside that may be used systemically. Drug of choice in simple mucocutaneous herpes simplex, in immunocompromised patients with initial herpes genitalis. Also active against herpes virus including herpes zoster and varicella.
ADENITIS
Inflammation of a lymph node or gland.
ADENOPATHY
Pathologic enlargement of glands, especially lymphatic glands.
ADENOVIRUS
A DNA virus 80 to 90 nanometers in size. It can cause respiratory illness and conjunctivitis in humans. Human adenoviruses comprise at least 31 serotypes that can be divided into three groups on the basis of oncogenicity.
ADHERENCE
The act or quality of uniting two or more surfaces or parts.
ADHESION
The property of remaining in close proximity; the molecular attraction existing between the surfaces of contacting bodies.
ADJUNCTIVE TREATMENT
Supplementary and additional therapeutic procedures. In periodontics, it generally refers to procedures other than scaling and root planing and surgical therapy, such as chemotherapy, occlusal therapy.
ADSORPTION
The attachment of a substance to the surface of another.
AEROBE
A microorganism that can live and grow in the presence of molecular oxygen.
AEROBIC
Environmental conditions that contain atmospheric levels of oxygen. Used in reference to microorganisms that grow optimally under these conditions. See also FACULTATIVE.
AGGREGATIBACTER ACTINOMYCETEMCOMITANS
A gram-negative, non-motile, facultatively anaerobic, rod-shaped bacterium found in subgingival and marginal plaque of healthy and periodontally diseased individuals. A periodontal pathogen that is implicated as a minor causative agent in chronic periodontitis but is more often associated as the predominant causative bacteria of aggressive periodontitis. Formerly named Actinobacillus actinomycetemcomitans. ALLELE: One of two or more different genes that may occupy the same locus on a specific chromosome.
ALLERGEN
A substance capable of producing allergy or specific hypersensitivity.
ALLERGY
The altered reactivity of a sensitized individual on exposure to an allergen.
ALVEOLAR CREST
The most coronal portion of the alveolar process.
ALVEOLUS
The socket in the bone into which a tooth is attached by means of the periodontal ligament.
AMERICAN SOCIETY OF ANESTHESIOLOGISTS (ASA) PATIENT CLASSIFICATION SYSTEM
System used as a basis for identifying the physical status of sedation patients.
ASA I: Normal, healthy patient.
ASA II: Patient with mild systemic disease.
ASA III: Patient with severe systemic disease that limits activity.
ASA IV: Patient with an incapacitating disease that is a constant threat to life.
ASA V: Moribund patient who is not expected to survive 24 hours
ASA VI: Patient is declared brain-dead and organs are being removed for transplant.
E: Emergency operation of any variety used to modify one of the above classifications.
