Multiple Choice

Which of the following is true concerning the number and type of permanent teeth in a typical adult human?

There are 20 permanent teeth, including only incisors and canines.

There are 28 permanent teeth, all of which are molars.

There are 32 permanent teeth, including incisors, canines, premolars, and molars.

There are 32 permanent teeth, but no premolars are present.

Verified step by step guidance

Step 1: Begin by understanding the anatomy of the human dentition. A typical adult human has two sets of teeth during their lifetime: primary (baby) teeth and permanent teeth. Permanent teeth replace primary teeth as a person matures.

Step 2: Recall the total number of permanent teeth in a typical adult human. There are 32 permanent teeth, which include different types of teeth specialized for various functions such as cutting, tearing, and grinding food.

Step 3: Identify the types of permanent teeth. These include incisors (used for cutting), canines (used for tearing), premolars (used for grinding), and molars (used for crushing and grinding). Each type has a specific role in the process of mastication (chewing).

Step 4: Break down the distribution of permanent teeth. In each quadrant of the mouth (upper right, upper left, lower right, lower left), there are 2 incisors, 1 canine, 2 premolars, and 3 molars. Multiply this distribution by 4 quadrants to confirm the total number of teeth.

Step 5: Evaluate the options provided in the problem. Compare the descriptions of the number and types of teeth in each option to the anatomical facts about permanent teeth. The correct answer should align with the presence of 32 permanent teeth, including incisors, canines, premolars, and molars.
