Mandibular incisor

Mandibular Incisor

The Mandibular Incisor is one of the four types of teeth found in the human mouth. They are located in the mandible, or lower jaw, and are primarily used for cutting and slicing food.

Anatomy

There are two types of mandibular incisors: the central incisor and the lateral incisor. The central incisor is located closest to the midline of the face, while the lateral incisor is located next to the central incisor. Each mandibular incisor has a single root and a sharp, flat edge, or cusp, for cutting food.

Development

The development of the mandibular incisors begins in the embryo during the sixth week of pregnancy. The process, known as odontogenesis, involves the formation of the tooth bud, the growth of the tooth, and the eruption of the tooth through the gums. The mandibular incisors are typically the first teeth to erupt, usually appearing between the ages of six and ten months.

Clinical significance

Mandibular incisors are often the first teeth to show signs of dental caries, or tooth decay, due to their location and the difficulty in cleaning them properly. They are also commonly affected by periodontal disease, which can lead to tooth loss if not treated. In addition, mandibular incisors can be affected by malocclusion, a condition in which the teeth do not align properly when the mouth is closed.
