Questions and Answers
  • 1. 

    How many teeth does an adult human have?

    • A.

      32

    • B.

      24

    • C.

      30

    • D.

      16

    Correct Answer
    A. 32
    Explanation
    An adult human typically has 32 teeth. This includes 8 incisors, 4 canines, 8 premolars, and 12 molars (including 4 wisdom teeth). These teeth serve various functions such as biting, tearing, and grinding food. The number of teeth can vary slightly from person to person, as some individuals may have fewer teeth due to dental issues or extractions. However, the average number of teeth in an adult human is 32.

    Rate this question:

  • 2. 

    What kind of tooth is adapted for cutting?

    • A.

      Canine 

    • B.

      Incisor 

    • C.

      Premolar 

    • D.

      Molar 

    Correct Answer
    B. Incisor 
    Explanation
    Incisors are adapted for cutting because they have a sharp, chisel-like edge that allows them to slice through food. They are located at the front of the mouth and are used for biting into and cutting food into smaller pieces. Canines, premolars, and molars have different shapes and functions, such as tearing, grinding, and chewing, but they are not specifically adapted for cutting like incisors are.

    Which of these pioneered the field?

    • D.

      Joe Rogers 

    Correct Answer
    C. Edward Angle 
    Explanation
    Edward Angle is the correct answer because he is widely recognized as the founder of modern orthodontics. He developed many important orthodontic techniques and principles that are still used today. Angle's contributions to the field include the classification system for malocclusions, the use of appliances to correct tooth and jaw alignment, and the establishment of orthodontics as a separate dental specialty. His work laid the foundation for the field of orthodontics and greatly advanced the understanding and treatment of dental and facial irregularities.

  • 4. 

    What is misalignment between dental arches called?

    • A.

      Malocclusion

    • B.

      Plaque

      Floss

    • D.

      Dental occlusion

    Correct Answer
    A. Malocclusion
    Explanation
    Malocclusion refers to the misalignment between dental arches, which can result in various dental issues such as overcrowding, overbite, or underbite. It can lead to difficulties in chewing, speaking, and maintaining oral hygiene. Malocclusion can be caused by factors like genetics, thumb sucking, or improper dental care. Treatment options for malocclusion include braces, dental appliances, or in severe cases, surgery.

  • 5. 

    Which of these is not located in the oral cavity?

      Tonsils

    • D.

      Pharynx

    Correct Answer
    D. Pharynx
    Explanation
    The pharynx is not located in the oral cavity. The oral cavity refers to the mouth, which includes the tongue, gums, and tonsils. The pharynx, on the other hand, is a passage that connects the mouth to the esophagus and the nasal cavity. It is located behind the oral cavity and serves as a pathway for both food and air.

    Explanation
    The main parts of a bracket are typically four in number. These include the left bracket, right bracket, top bracket, and bottom bracket. These parts are used to enclose or group together elements in mathematics, programming, or other contexts.

    Rate this question:

  • 7. 

    Which of these parts of brackets is used to spot weld onto orthodontic bands?

    • A.

      Wire slots 

    • B.

      Bracket base 

    • C.

      Tie wing 

    • D.

      Arch wires 

    Correct Answer
    B. Bracket base 
    Explanation
    The correct answer is "Bracket base." In orthodontics, spot welding is used to attach orthodontic bands to the teeth. The bracket base is the part of the bracket that is directly bonded to the tooth surface, providing a stable foundation for the orthodontic treatment. The wire slots, tie wings, and arch wires are all components of the bracket that play different roles in the orthodontic treatment process but are not specifically used for spot welding onto orthodontic bands.

    Rate this question:

  • 8. 

    Which of these is used on the premolar?

    • A.

      Orthodontic bands 

    • B.

      Arch wire

    • C.

      Coils 

    • D.

      Springs

    Correct Answer
    A. Orthodontic bands 
    Explanation
    Orthodontic bands are used on the premolars. These bands are metal rings that are placed around the tooth and serve as an anchor for other orthodontic appliances. They provide support and stability for various orthodontic treatments, such as braces or retainers. The bands are custom-made to fit each individual tooth and are typically placed on the premolars and molars to provide a strong foundation for the orthodontic treatment.

    Rate this question:

  • 9. 

     Which of these is done to prevent orthodontic movement?

    • A.

      Malocclusion

    • B.

      Adjunctive therapy 

    • C.

      Alveolar decortication

    • D.

      Disocclusion

    Correct Answer
    B. Adjunctive therapy 
    Explanation
    Adjunctive therapy is done to prevent orthodontic movement. This type of therapy involves using additional treatments or procedures alongside orthodontic treatment to enhance the results and prevent unwanted movement. It can include the use of appliances, exercises, or medications to support the orthodontic treatment and ensure that the teeth and jaw remain in their desired positions. By combining adjunctive therapy with orthodontic treatment, orthodontists can achieve better and more stable results for their patients.

    Rate this question:

  • 10. 

    Which of these is not a way of treating malocclusion?

    • A.

       Growth Modification

    • B.

      Orthodontic Camouflage

    • C.

      Facial Aesthetics

    • D.

      Orthognathic Surgical Treatment

    Correct Answer
    C. Facial Aesthetics
    Explanation
    Facial aesthetics is not a way of treating malocclusion. Malocclusion refers to misalignment of the teeth and jaws, and it requires orthodontic or surgical interventions to correct it. Growth modification involves using appliances to guide the growth of the jaws and correct malocclusion in children. Orthodontic camouflage involves using braces or aligners to move the teeth into proper alignment. Orthognathic surgical treatment involves surgically repositioning the jaws to correct severe malocclusion. Facial aesthetics, on the other hand, focuses on enhancing the appearance of the face through procedures like botox, fillers, or facelifts, but it does not directly address malocclusion.
