    The dental specialty that deals with the removal of the pulp is:

    • Orthodontics

    • Periodontics

    • Oral Surgery

    • Endodontics

    • Pathology

    Correct Answer
    A. Endodontics
    Explanation
    Endodontics is the dental specialty that deals with the removal of the pulp. The pulp is the soft tissue inside the tooth that contains nerves, blood vessels, and connective tissue. Endodontists are trained to perform root canal treatments, which involve removing the infected or damaged pulp from the tooth and then cleaning, shaping, and filling the root canal system. This specialty focuses on saving teeth and treating conditions that affect the dental pulp, such as tooth decay, dental trauma, and pulp infections. Orthodontics, periodontics, oral surgery, and pathology are different dental specialties that deal with other aspects of dental care.

    A bump found on the crown of a tooth is called:

    • Primary groove

    • Fissure

    • Pit

    • Cusp

    • Cervix

    Correct Answer
    A. Cusp
    Explanation
    A bump found on the crown of a tooth is called a cusp. This term refers to the elevated point or ridge on the chewing surface of a tooth that helps in the process of breaking down food during chewing. Each tooth typically has one or more cusps, which vary in shape and size depending on the type of tooth. The cusps play a crucial role in the overall function and effectiveness of the tooth in the chewing process.

    The hardest tissue in the body is:

    • Bone

    • Cementum

    • Dentin

    • Enamel

    • Pulp

    Correct Answer
    A. Enamel
    Explanation
    Enamel is considered the hardest tissue in the body. It is the outermost layer of the tooth and provides protection to the underlying structures. Enamel is composed of a mineral called hydroxyapatite, which gives it its hardness. It is highly mineralized and does not contain living cells, making it resistant to wear and decay. Enamel is stronger than bone, dentin, cementum, and pulp, which are all other tissues found in the body.

    Which teeth are not found in primary dentition?

    • Molars

    • Cuspids

    • Bicuspids

    • Incisors

    • Laterals

    Correct Answer
    A. Bicuspids
    Explanation
    Bicuspids are not found in primary dentition. Primary dentition refers to the set of teeth that a child has before their permanent teeth come in. Bicuspids, also known as premolars, are the teeth located between the molars and the cuspids. They are not present in primary dentition and only appear when the permanent teeth begin to erupt.

  • 11. 

    The bulk of the tooth is made up of:

    • Enamel

    • Cementum

    • Dentin

    • Pulp

    • Tubules

    Correct Answer
    A. Dentin
    Explanation
    Dentin is the correct answer because it makes up the bulk of the tooth. Dentin is a hard, calcified tissue that lies underneath the enamel and cementum. It forms the main structure of the tooth and provides support and protection. Dentin contains microscopic tubules that connect to the pulp, which is the innermost part of the tooth. These tubules allow for the transmission of sensations such as hot or cold temperatures. Enamel is the outermost layer of the tooth, cementum covers the root surface, and pulp is the soft tissue containing nerves and blood vessels.

    The band of connective tissue found next to the bicuspids and lips is called:

    • Frenum

    • Mucosa

    • Labia

    • Alveolar ridge

    • Tuberosity

    Correct Answer
    A. Frenum
    Explanation
    The band of connective tissue found next to the bicuspids and lips is called a frenum. A frenum is a small fold of tissue that helps to stabilize and support the movement of the lips and tongue. It can be found in various locations in the mouth, including the area next to the bicuspids. The other options, mucosa, labia, alveolar ridge, and tuberosity, do not specifically refer to the band of tissue next to the bicuspids and lips.

    Correct Answer
    A. Cleoid discoid
    Explanation
    A cleoid discoid is a dental instrument used to carve tooth anatomy in a restoration. It has a disc-shaped working end with two different shaped sides - a cleoid side and a discoid side. The cleoid side is used to carve grooves and fossae on the occlusal surface of the tooth, while the discoid side is used to carve smooth, rounded surfaces. This instrument allows for precise shaping and carving of tooth anatomy during the restorative process.

    The portion of the tooth that is visible in the mouth is called the:

    • Cusp

    • Anatomic Crown

    • Tooth

    • Clinical Crown

    • Enamel

    Correct Answer
    A. Clinical Crown
    Explanation
    The clinical crown refers to the part of the tooth that is visible in the mouth above the gum line. It is the portion of the tooth that can be seen when we smile or open our mouths. The clinical crown does not include the root of the tooth that is embedded in the jawbone. This term is commonly used in dentistry to differentiate between the visible part of the tooth and the part that is hidden beneath the gums.

    • Class V

    • Class I

    • Class II

    • Class III

    • Class IV

    Correct Answer
    A. Class II
    Explanation
    A tofflemire & matrix band is used to form a wall for cavity classification in Class II. This type of cavity involves the proximal surfaces of posterior teeth, specifically involving two or more surfaces. The tofflemire & matrix band helps to create a tight seal and provide support for the restorative material used to fill the cavity.

    Which type of dental cement is used to irritate the dentin and stimulate the growth of secondary dentin?

    • Lining Base

    • Insulating Base

    • Amalgam

    • Varnish

    • Composite

    Correct Answer
    A. Insulating Base
    Explanation
    Insulating base is the correct answer because it is a type of dental cement that is used to irritate the dentin and stimulate the growth of secondary dentin. Secondary dentin is formed in response to irritation or injury to the pulp, and the insulating base is specifically designed to promote this process. It helps protect the pulp from further damage and encourages the formation of new dentin, which can help strengthen and protect the tooth.

    The dividing line between the anatomic crown and the root of the tooth is called:

    • Cementum

    • Midline

    • Cervix (CEJ)

    • Cusp

    • Tubule

    Correct Answer
    A. Cervix (CEJ)
    Explanation
    The dividing line between the anatomic crown and the root of the tooth is called the cervix. This term is commonly used in dentistry to refer to the point where the enamel of the crown meets the cementum of the root. It is also known as the cementoenamel junction (CEJ). The cervix is an important landmark in dental anatomy and is significant for various dental procedures, including restorative and periodontal treatments.

    • Alveolar ridge

    • Tuberosity

    • Retro Molar Pad

    • Foramen

    • Alveolar socket

    Correct Answer
    A. Tuberosity
    Explanation
    The area found just behind the upper 3rd molar is called the tuberosity. The tuberosity is a bony prominence that provides support for the attachment of the muscles involved in chewing. It helps to distribute the forces exerted during chewing and prevents excessive pressure on the surrounding structures.

    Which of the following is the primary responsibility of a dental assistant during a restorative dental procedure?

    • Administering anesthesia

    • Handling and passing instruments

    • Performing tooth extractions

    • Diagnosing dental conditions

    Correct Answer
    A. Handling and passing instruments
    Explanation
    During a restorative dental procedure, the primary responsibility of a dental assistant is handling and passing instruments to the dentist. The dental assistant ensures that the dentist has the necessary tools quickly and efficiently, helping maintain a sterile environment and smooth workflow. While assisting, they also manage suctioning, mixing dental materials, and keeping the patient comfortable. Tasks like administering anesthesia or diagnosing dental conditions are performed by dentists or specialists, not dental assistants.

    • 1

    • 2

    • 3

    • 4

    • 5

    Correct Answer
    A. 2
    Explanation
    A size 2 hole is typically used for a 1st molar when using a rubber dam. The size of the hole refers to the diameter of the opening in the rubber dam through which the tooth is isolated. The size 2 hole is suitable for a 1st molar because it provides a snug fit around the tooth, ensuring effective isolation and protection during dental procedures.
