Study Notes
Overview of Teeth and Jaw Structure
- The lower jaw is known as the mandible.
- The upper jaw is referred to as the maxilla.
- Teeth are symmetrical; each type appears in both jaws.
Types of Teeth
-
Central Incisors
- Four total: two in the lower jaw and two in the upper jaw.
- Primary function: cutting food. The name "incisor" relates to making an incision.
-
Lateral Incisors
- Four total, similar to central incisors.
- Used for cutting as well.
-
Canines (Fangs)
- Four total; found between incisors and premolars.
- Longest and sharpest teeth, used for gripping food (e.g., tearing bread).
-
Premolars
- Eight total; two on each side of both jaws.
- Primary function: grinding food, derived from the Latin word "mola," meaning grindstone.
-
Molars
- Twelve total; three on each side of both jaws.
- Used for grinding food, similar function to premolars.
Wisdom Teeth
- Third molars are referred to as wisdom teeth.
- 72% of the population has their wisdom teeth removed.
- Commonly removed due to insufficient space in the gums for eruption, leading to potential complications like inflammation or infection.
- Eruption of wisdom teeth usually occurs between ages 17 to 25.
Dental Health Considerations
- Eruption issues arise when wisdom teeth attempt to grow through gingiva (gums), leading to pain and potential health risks.
- Regular dental check-ups using methods like X-rays can help monitor wisdom teeth development and prevent complications.
Interesting Dental Facts
- The typical textbook representation of the jaw is accurate for only 28% of individuals.
- The panoramic X-ray is a diagnostic tool for evaluating tooth alignment and wisdom teeth status.
