Liners, Temporary Restorations, and Coronal Polishing

These vocabulary flashcards cover the fundamental concepts of restorative dentistry, cavity liners, temporary restorations, and coronal polishing techniques based on Chapter 9 and 10 lecture notes.

Restorative Dentistry

The process of restoring teeth to their original form, function, and shape through the use of direct or indirect restorative materials.

Cavity preparation

The process of removing all diseased tooth structure while leaving the healthy tooth structure that is remaining.

Pulpitis

Inflammation of the pulp which can be caused by decay, traumatic occlusion, cavity preparation, desiccation, chemical irritants, thermal changes, or lack of a marginal seal.

Desiccation

A process that dehydrates and destroys pathogenic biofilm, calculus, and necrotic tissue in periodontal pockets.

Cavity Liner

A thin and weak layer used only for chemical protection of the deepest areas in the tooth preparation, specifically the pulpal floor or axial wall.

Dentin Stimulator

A function of liners used to protect the pulp and accelerate the formation of reparative dentin.

Sealers

Materials used to seal dentinal tubules; they may also be referred to as liners when applied thinly.

Varnish

A topical preventative treatment applied to prevent decay, remineralize enamel, and treat sensitivity.

Eugenol

An oily substance found in $IRM$ that interferes with resin adhesion to dentin.

Glass ionomers

Materials that can be used as temporary restorations before resins have been placed.

Self Cured

A material that sets by a chemical reaction triggered by mixing a base and a catalyst or a base and an accelerator.

Dual Cured

A material that uses a chemical reaction for initial placement and requires light to achieve a final set.

Light Cured

A material that uses a light to set; some are sensitive enough that overhead light can begin the setting process.

Plaque

A soft, sticky, colorless mass of bacteria that constantly sticks to the crown of the teeth and feeds on sugar to produce acid.

Calculus

Hardened plaque, also known as tartar.

Disclosing solution

A liquid painted around the teeth that temporarily dyes them to help analyze any remaining plaque.

Dental Caries

An infectious, communicable disease transmittable by bacterial infection, primarily involving streptococci and lactobacilli.

Fluoride Varnish ($5\%$ Neutral)

A professional application used for caries prevention, elimination of hypersensitivity, and strengthening teeth against solubility.

Coronal

The clinical portion of the tooth crown that is cleaned during polishing.

Intrinsic stains

Stains incorporated within the tooth structure, such as those from tobacco, pulpless teeth, or tetracycline, which cannot be removed by scaling or polishing.

Extrinsic stains

Stains found on the outside of the tooth caused by food, drinks, iron supplements, or chlorohexidine, which are easier to polish away.

Indirect illumination

A use of the dental mirror where light is reflected off the mirror surface to light up the oral cavity.

Indirect vision

A use of the dental mirror where the clinician looks directly into the mirror to see the tooth surface.

Retraction

Using a dental mirror to pull against the cheek side for better accessibility and visibility.

Prophy Angle

A prophylaxis angle connected to a slow-speed dental handpiece used for coronal polishing.

Fulcrum

A finger rest used to stabilize the handpiece or instrument, prevent injury to tissues, and provide control.

Xerostemia

Dry mouth, commonly seen in patients undergoing chemotherapy, often treated with Biotene products.

Mouthrinse

A liquid solution swished around the mouth to promote oral hygiene, reduce discomfort, or provide moisture to oral tissues.

EDDA

Expanded Duty Dental Assistant; a certified professional who can perform coronal polishing, apply fluoride, and apply desensitizing agents.
