Which instrument is designed to remove supragingival calculus from anterior teeth?
elena55 [62]

Periodontal curettes instrument is designed to remove supragingival calculus from anterior teeth.

What is periodontal curette ?

Periodontal curettes have a rounded back and toe, one face, and one or two cutting edges. They are often the tool of choice for removing supragingival calculi. When doing nonsurgical periodontal therapy as part of a patient's oral hygiene care, universal and Gracey curettes are frequently employed.

What type of instrument is periodontal curette ?

ultrasound instruments The main kind of treatment for eliminating plaque and calculus is ultrasound technology. These power-driven devices oscillate at incredibly fast rates, creating tiny vibrations that help eliminate calculus and subgingival plaque.

All matter is composed of atoms or molecules that have energy of motion, which is also known as _____. kinetic energy solar ener
lora16 [44]

Answer:

kinetic energy

Explanation:

When the molecules or atoms of a substance have high kinetic energy, the atoms/molecules move rapidly and collide frequently and harder. Most collisions are inelastic meaning that some of the energy in the collision is lost mostly as heat. This is why increasing the kinetic energy of a substance’ atoms/molecules causes the temperatures of the substance to rise. This is how heating by magnetic induction works.

Describe accurately the the basement membrane which underlies epithelial tissues
Nady [450]

Answer:

The basement membrane or basal lamina on which the epithelium form, made by extracellular matrix.

Explanation:

The basement membrane is the layer underlies all epithelia that is made up extracellular matrix secreted by the epithelium cells that provide structural support to the structure of epithelia.

It forms the barrier between epithelial tissues therefore once a epithelial cancer penetrate this basement membrane it will spread to all underlying tissues.

Thus, the correct answer is - The basement membrane or basal lamina on which the epithelium form, made by extracellular matrix.

The basement membrane is form of extracellular matrix that underlies all epithelia. It provides structural support to epithelia and forms a mechanical connection between epithelia and underlying connective tissue.

The basement membrane, or basal lamina, is a sheet of proteins and other substances to which epithelial cells adhere and that forms a barrier between tissues.

Epithelial cancers may have the ability to penetrate through the basement membrane and spread to underlying tissues.
