Dental Materials and Fluid Control Quiz

Maintaining a dry and clean operating field for better access, visibility, and patient comfort. It also prevents swallowing or aspirating foreign bodies, ensures the success of dental materials, controls infection, reduces aerosol production, minimizes mirror fogging, and prevents contamination.

Saliva, blood, and gingival crevicular fluids are all sources of moisture that can interfere with dental procedures.

Methods of controlling moisture in the dental environment. They include techniques like mechanical barriers, chemical agents, and other innovative approaches.

Techniques that involve physical barriers or devices to prevent fluid from reaching the treatment area. Examples include rubber dams, suction tips, and high-volume vacuums.

Methods utilizing specific chemicals to reduce salivary flow. Commonly used drugs include anti-sialagogues and local anesthetics.

Drugs that block the action of myoepithelial cells in salivary glands, reducing saliva production. Examples include Bromide, Propantheline bromide, Clonidine hydrochloride, and Atropine.

These techniques involve mechanically retracting gingival tissues to expose the tooth, but they are often associated with complications like tissue trauma.

This technique combines mechanical retraction with a chemical agent like ferric sulfate to displace gingiva, providing better access and reducing bleeding.

The branch of dentistry focused on restoring oral function, comfort, appearance, and health through replacing missing teeth with artificial substitutes.

The area of prosthodontics that uses artificial substitutes that are fixed to natural teeth, roots, or implants.

Any artificial replacement of a missing body part.

The area of prosthodontics that uses removable artificial substitutes to replace missing teeth.

The process of restoring a damaged tooth or replacing a missing tooth with a permanent artificial substitute.

The movement of teeth due to the absence of opposing teeth.

The loss of bone surrounding the teeth due to lack of function and pressure.

The aim to restore proper chewing function, including the ability to grind and tear food.

Restoring the natural appearance of teeth, including shape, color, and alignment.

Maintaining the health of the remaining teeth and gums, preventing further tooth loss.

The amount of tooth structure removed from the occlusal surface during crown preparation.

Grooves placed on the surface of the tooth to guide the preparation, ensuring the right amount of tooth structure is removed.

The space created between the prepared tooth and the opposing tooth during occlusion. It should be 1.5mm on functional cusps and 1mm on nonfunctional cusps.

A beveled edge created on the buccal inclines of lower buccal cusps and palatal inclines of upper palatal cusps to improve the crown's fit and function.

The process of reducing the tooth's axial (side) surfaces to create a proper shape for the crown. Includes buccal, lingual, mesial, and distal surfaces.

A type of preparation finish line that creates a smooth, rounded margin for the crown. It is commonly used for all-metal crowns.

The amount of tooth structure removed from the occlusal surface for a crown preparation. It should be 1-1.5mm to ensure enough metal thickness.

Reducing the occlusal surface by preparing two planes, buccal, and lingual, to create a uniform thickness for the crown in pulpless teeth.

Tools used to measure the amount of tooth structure removed during the preparation process, ensuring the correct amount of reduction.

The amount of occlusal surface preparation.

A concave shape located on the lingual surface of the tooth, designed to ensure even clearance during tooth preparation.

A rounded, mesio-distally curved contour on the facial surface of the tooth, offering retention and resistance during preparation.

This instrument is shaped like a wheel or oval and is used to prepare the concave lingual fossa.

This instrument has a tapered form with a flat end and is specifically designed for preparing the cingulum.

A preparation margin shape that has a smooth, rounded edge, creating a 1mm width.

A preparation margin shape that has a sharp angle and is tapered to create a 1mm width.

The amount of tooth structure removed in the proximal area during preparation. Typical reduction is 1mm.

The direction of tooth reduction, starting from the labial side (front) towards the lingual side (tongue) of the tooth.

A fine tapered instrument that is used to initially open up the contact area between two teeth during proximal reduction.

This process includes smoothing all the surfaces of the tooth preparation, rounding sharp corners, and defining the finish line using specialized instruments.

Type of dental restoration that covers the entire crown of a tooth with a non-metallic material, offering a more aesthetically pleasing alternative to metal crowns. These restorations are designed to restore the tooth's shape, function, and esthetics.

A specific type of ceramic material typically composed of kaolin, quartz, and feldspars, often used in dental restorations to enhance aesthetics. Porcelain is known for its translucency, allowing light to pass through it, mimicking the natural appearance of teeth.

The addition of alumina crystals to traditional porcelain, resulting in increased strength and ability to withstand fracture. However, this higher strength comes at the cost of reduced translucency, making it opaque.

A technique where a stronger, opaque core material is placed within a tooth, and then covered with a thinner, translucent layer of ceramic to achieve the desired esthetics. Similar to a metal-ceramic crown, but the core is not metal!

Relatively new ceramic materials like zirconia often utilized in dental restorations. Known for strength, durability, and esthetics, they address the weaknesses of traditional ceramics. These materials are often incorporated with CAD/CAM technology to improve accuracy and efficiency.
