INCISOR Meaning and
Definition
-
An incisor refers to one of the primary types of teeth found in mammals, including humans, located in the front of the mouth. These teeth play a fundamental role in biting, cutting, and tearing food during mastication. Incisors are typically characterized by their sharp edges, smooth appearance, and comparatively simple shape. Humans generally have eight incisors, four in the upper jaw and four in the lower jaw, with two central incisors in the middle and two lateral incisors on either side.
The primary function of incisors is to facilitate the initial breakdown of food, preparing it for further digestion. They possess a strong and sturdy structure, aiding in the process of cutting and biting, as well as grasping objects. Incisors are positioned in the mouth with their surfaces facing forward, allowing for efficient gripping and shearing actions. Additionally, they contribute to the pronunciation of certain sounds, such as the "s" and "th" sounds in speech.
Incisors are distinguishable from other teeth by their relatively shorter and narrower shape, lacking cusps or deep roots. They are predominantly flat on the biting surface, exhibiting a chisel-like appearance. The enamel covering the crown of incisors is the hardest substance in the human body, providing protection and durability necessary for their task. Overall, incisors play a vital role in the proper functioning of the mouth and the oral phase of digestion, aiding in both the breaking down of food and the articulation of speech.
