Külglõikehambad

Külglõikehambad, also known as lateral incisors, are a type of tooth located in the mouth. They are situated between the central incisors and the canine teeth. In humans, there are two permanent külglõikehambad, one on each side of the upper jaw, and two on each side of the lower jaw, making a total of four. These teeth play a role in biting and tearing food, although their primary function is generally considered to be assisting the central incisors in cutting.

The morphology of külglõikehambad can vary. They are typically smaller and narrower than central incisors, with a single root. The shape of the crown can be somewhat pointed or blade-like, which aids in their function. In some cases, particularly in the lower jaw, külglõikehambad may be unusually small or even absent, a condition known as hypodontia. This variability can be influenced by genetic factors.

The eruption of permanent külglõikehambad occurs at different times for the upper and lower teeth. In the upper jaw, they usually erupt between the ages of 7 and 8 years, while in the lower jaw, they typically emerge between 6 and 7 years of age. Like other teeth, külglõikehambad are susceptible to decay and other dental issues if proper oral hygiene is not maintained. Their position in the dental arch also makes them important for the overall alignment and function of the dentition.
