The patient, a 12-year-old boy, shows several areas of tooth decay: #3 mesial, #12 occlusal, #20 occlusal, and #30 on the occlus
yawa3891 [41]

Since the amount of decay is too much, the dental assistant should respond by advising the mother of the patient to reduce the quantity of sugary food intake and to enhance oral hygiene.

A dental assistant is an individual that are usually certified to assist dentists during dental treatment procedures.

During a dental procedure, they help to perform the following tasks:

  • preparing patients for the treatment,
  • passing dentists instruments and other materials, and
  • keeping patients' mouths dry and clear using suction and other devices.

Tooth decay is the formation of a hole through the tooth cavity.

Tooth decay can occur in several areas when there is poor oral hygiene and excess intake of sugary foods.

When sugary food is taken in excess without proper oral hygiene, it reacts with plaque bacteria in the mouth producing acids.

The acid then dissolves your enamel slowly, creating the cavities in your teeth.

Therefore, the dental assistant should respond by advising the mother of the patient to reduce the quantity of sugary food intake and to enhance oral hygiene.

Which of the following is characteristics of a steroid hormone action?
aleksklad [387]

Answer:

internal receptor binding

Explanation:

This is because steroid hormones are lipids by nature (usually composed of cholesterol) so they are hydrophobic. This means that steroid hormones can easy pass through the membrane and bind to their internal receptors.

Internal receptors also known as intracellular receptors have DNA binding domain and when hormones bind to them DNA-binding site becomes exposed. Hormone-receptor complex gets into the nucleus and binds to  regulatory regions of the DNA. Cellular response is gene expression.
