2.
What do you bite into to leave your bite mark to show how your teeth are aligned?
Correct Answer
D. Wax
Explanation
Wax is a material that can be easily bitten into and leave a clear impression of the teeth. It is commonly used in dental procedures to create molds of the teeth and assess the alignment. Biting into wax allows the dentist or orthodontist to examine how the upper and lower teeth come together, helping them determine if there are any alignment issues or abnormalities. Plastic, rubber, and steel are not typically used for this purpose and may not provide the same level of detail or accuracy as wax. Therefore, the correct answer is wax.

Enamel, cementum, pulp and what are the major components of a tooth?
Correct Answer
D. Dentin
Explanation
Dentin is one of the major components of a tooth, along with enamel, cementum, and pulp. Dentin is a hard, calcified tissue that forms the bulk of the tooth structure. It lies beneath the enamel and cementum and surrounds the pulp, providing support and protection. Dentin is composed of microscopic tubules that contain fluid and nerve fibers, allowing for sensation and transmitting stimuli to the pulp. It is responsible for giving the tooth its shape and strength.
8.
How many types of dentin are there?
Correct Answer
D. Three
Explanation
There are three types of dentin. Dentin is a hard tissue that makes up the majority of a tooth. The three types of dentin are primary dentin, secondary dentin, and tertiary dentin. Primary dentin forms during tooth development, secondary dentin forms after the tooth has erupted, and tertiary dentin forms in response to injury or decay. Each type of dentin serves a different purpose in maintaining the structure and function of the tooth.
9.
Swollen gums, gums that are tender and bleeding are signs of what disease?
Correct Answer
