Question 1

Identify the item that is placed on the buccal mucosa, inside the cheek, opposite the maxillary second molar near the Stensen's duct that best absorbs saliva originating from the parotid gland.&#10;A)Cotton rolls&#10;B)Cotton roll holder&#10;C)Dry Aid&#10;D)None of the above

Accepted Answer

Dry Aid is a small device that is designed to be placed on the buccal mucosa of the oral cavity, opposite the maxillary second molar near the Stensen's duct. It is made of a special material that is highly absorbent, and it is used to absorb saliva that originates from the parotid gland. Dry Aid is the best choice for this purpose, as cotton rolls and cotton roll holders are not designed specifically for this application.

Question 2

Fluoride treatments are given&#10;A)to help make the structure of the teeth smooth and shiny.&#10;B)once a month.&#10;C)to help prevent decay by mineralizing the teeth.&#10;D)None of the above

Accepted Answer

Fluoride treatments are given to help prevent decay by mineralizing the teeth. The fluoride helps make the tooth enamel stronger and more resistant to acid attacks from bacteria in plaque and sugar in the diet. It can also reverse early stages of tooth decay. Fluoride treatments are usually recommended every 3, 6 or 12 months depending on a person's risk for cavities. They are typically done in the dental office, but can also be given in the form of fluoride toothpaste, mouthwash or supplements. Fluoride treatments are not meant to make the teeth smooth and shiny, nor are they given every month as a routine.

Question 3

The Diagnodent unit is used to&#10;A)measure the length of the canal in the root of the tooth.&#10;B)detect calculus subgingivally.&#10;C)detect the pit and fissures of the tooth structure.&#10;D)detect caries within the tooth structure.

Accepted Answer

The Diagnodent unit is used to detect caries within the tooth structure by using laser fluorescence technology. It measures the amount of fluorescence reflected back from the tooth; healthy tooth structure reflects less fluorescence than tooth structure affected by caries.

Question 4

_________________ is one of the new devices that can be used to detect caries in the structure of the tooth prior to placing sealants.&#10;A)Diagnodent&#10;B)Intraoral camera&#10;C)Neither a nor b is correct

Accepted Answer

The Diagnodent is a device used to detect caries and is commonly used prior to placing sealants. Intraoral cameras, on the other hand, are used to capture images of the inside of the mouth for diagnostic purposes but do not detect caries.

Question 5

Fluoride treatments usually are given to children&#10;A)once a month.&#10;B)once every 2 months.&#10;C)once every 4 months.&#10;D)once every 6 months.&#10;E)once every 2 years.

Accepted Answer

According to the American Dental Association, fluoride treatments should be given to children once every 6 months. This helps to prevent tooth decay and promote overall dental health.
