TEST YOURSELF ON THE TEETH - MCQ
1. Which of the following is the hardest substance in the human body?
A) Enamel
Answer: A) Enamel
Rationale: Enamel is the outermost layer of the tooth, and it is the hardest substance in the human body. It protects the tooth from wear and tear caused by chewing and other activities. Dentin is the layer under the enamel and is less hard than enamel but still quite durable. Pulp is the soft tissue located in the center of the tooth, while cementum is the layer of connective tissue that covers the root of the tooth.
2. What is the function of the periodontal ligament?
Answer: A) It provides shock absorption during chewing
Rationale: The periodontal ligament is the tissue that attaches the cementum to the bone that surrounds the tooth. It provides shock absorption during chewing and helps to keep the tooth stable. It does not nourish the tooth or protect it from wear and tear, and while it does anchor the tooth to the jawbone, this is not its primary function.
Answer: A) Incisors
Answer: D) Molars
Answer: C) Pulp
Answer: B) TartarWhat is the term for a tooth that has not emerged from the gumline? A) Impacted B) Decayed C) Infected D) Abscessed
Answer: A) Impacted
Answer: C) Decay
Answer: B) Canine
Answer: A) Extraction
Answer: B) Crown
Answer: C) Malocclusion
STRUCTURE OF THE TEETH
Teeth are a crucial component of the human body's digestive system. They are responsible for mechanically breaking down food into smaller pieces, which aids in the digestion process. Teeth are composed of multiple layers of specialized tissues that work together to support the tooth's function.
A normal adult mouth has 32 teeth, which have erupted by about age 13, except the wisdom teeth.• Incisors (8 total): The middlemost four teeth on the upper and lower jaws.
• Canines (4 total): The pointed teeth just outside the incisors.
• Premolars (8 total): Teeth between the canines and molars.
• Molars (8 total): Flat teeth in the rear of the mouth, best at grinding food.
• Wisdom teeth or third molars (4 total): These teeth erupt at around age 18, but are often surgically removed to prevent displacement of other teeth.
The anatomy of the tooth can be divided into two parts: the crown and the root. The crown is the visible portion of the tooth above the gumline, while the root is the portion of the tooth that is embedded in the jawbone.
Here are the different layers of the tooth and their functions:
Enamel - This is the hard, outermost layer of the tooth. It is the hardest substance in the body and protects the tooth from wear and tear.
Dentin - This is the layer under the enamel that makes up most of the tooth's structure. It is less hard than enamel but still quite durable. Dentin is responsible for giving teeth their color.
Pulp - This is the soft tissue located in the center of the tooth. It contains nerves, blood vessels, and connective tissues that nourish the tooth and keep it healthy.
Cementum - This is the layer of connective tissue that covers the root of the tooth. It anchors the tooth to the jawbone and helps to hold it in place.
Periodontal Ligament - This is the tissue that attaches the cementum to the bone that surrounds the tooth. It provides shock absorption during chewing and helps to keep the tooth stable.
Overall, the different layers of the tooth work together to support the tooth's function in the digestive process. Proper dental hygiene, such as regular brushing and flossing, can help to keep these layers healthy and prevent tooth decay and other oral health problems.
