Anterior and posterior dentition refer to the teeth that are located in the front and back of the mouth, respectively. Here are the differences between the two in terms of the teeth that comprise each of them and their general function:
A. Teeth that comprise anterior and posterior dentition:
1. Anterior dentition: Anterior dentition refers to the teeth that are located in the front of the mouth, including the incisors and canines. Incisors are the four front teeth in the upper and lower jaw, while canines are the sharp, pointy teeth located next to the incisors.
2. Posterior dentition: Posterior dentition refers to the teeth that are located in the back of the mouth, including the premolars and molars. Premolars are located between the canines and molars, while molars are the largest teeth in the mouth, located at the back of the jaw.
B. General function of anterior and posterior dentition:
1. Anterior dentition: The primary function of anterior dentition is to cut and tear food. Incisors have sharp edges that are ideal for biting off pieces of food, while canines are used to tear into tougher foods like meat.
2. Posterior dentition: The primary function of posterior dentition is to grind and crush food. Premolars and molars have flat surfaces that are ideal for grinding food into smaller pieces, making it easier to swallow and digest.
In summary, anterior dentition includes the front teeth, incisors, and canines, which are used to cut and tear food. Posterior dentition includes the back teeth, premolars, and molars, which are used to grind and crush food. Understanding the differences between anterior and posterior dentition can help with proper dental care and maintenance of oral health.
