How many teeth does an adult human have?
- A.
32
- B.
24
- C.
30
- D.
16
Correct Answer
A. 32Explanation
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:

What kind of tooth is adapted for cutting?
- A.
Canine
- B.
Incisor
- C.
Premolar
- D.
Molar
Correct Answer
B. IncisorExplanation
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.Rate this question:

Who pioneered the field of orthodontics?
- A.
William Ferguson
- B.
Maurice Stone
- C.
Edward Angle
- D.
Joe Rogers
Correct Answer
C. Edward AngleExplanation
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.Rate this question:

What is misalignment between dental arches called?
- A.
Malocclusion
- B.
Plaque
- C.
Floss
- D.
Dental occlusion
Correct Answer
A. MalocclusionExplanation
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.Rate this question:

Which of these is not located in the oral cavity?
- A.
Tongue
- B.
Gum
- C.
Tonsils
- D.
Pharynx
Correct Answer
D. PharynxExplanation
The pharynx, also known as the throat, is not located in the oral cavity but rather behind it, connecting the mouth and nasal passages to the esophagus and larynx. The oral cavity includes structures such as the tongue, gums, and teeth. Tonsils are also considered part of the oral cavity as they are located at the back of the throat near the pharynx. The pharynx plays a crucial role in both the respiratory and digestive systems, helping to pass air to the lungs and food to the esophagus.Rate this question:

How many are the main parts of a bracket?
- A.
4
- B.
5
- C.
6
- D.
7
Correct Answer
A. 4Explanation
A typical orthodontic bracket, used in braces to align and straighten teeth, consists of four main parts. These include the base, which is attached directly to the tooth; the slot, where the archwire is placed; the tie wings, which hold the archwire in place; and sometimes a hook, used for attaching elastics. These components work together to hold the archwire that moves the teeth into the desired position over time. The bracket system is fundamental in orthodontic treatments as it provides the necessary force to correct malocclusions and improve dental alignment.Rate this question:

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 baseExplanation
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:

Which of these is used on the premolar?
- A.
Orthodontic bands
- B.
Arch wire
- C.
Coils
- D.
Springs
Correct Answer
A. Orthodontic bandsExplanation
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:

Which of these is done to prevent orthodontic movement?
- A.
Malocclusion
- B.
Adjunctive therapy
- C.
Alveolar decortication
- D.
Disocclusion
Correct Answer
B. Adjunctive therapyExplanation
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:

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 AestheticsExplanation
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.Rate this question:
