When you flash your biggest and brightest smile, your central incisor teeth are front and center. These are the two upper and lower teeth at the very front of your mouth. On either side of your central incisors are the lateral incisors, making eight incisors in total..
How many roots does a central incisor have?
The maxillary central incisors are frequently to be reported to have only one root and one canal, and some clinical reports described a maxillary central incisor with two canals or two root. The maxillary central incisor with three or four root canals were very rarely been reported..
What is the anatomy of the incisors?
All eight incisors share a general tooth anatomy, consisting of a crown that is continued by the root. The crown is covered by enamel, while the root is covered by cementum. The body of the tooth consists almost entirely of dentine which surrounds a central pulp cavity..
What is the facial anatomy of the central incisor?
The maxillary central incisor is a human tooth in the front upper jaw, or maxilla, and is usually the most visible of all teeth in the mouth. It is located mesial (closer to the midline of the face) to the maxillary lateral incisor..
What is the surface anatomy of the central incisor?
Lingually, the surface form of the maxillary central incisor is more irregular. The largest part of the middle and incisal portions of the lingual area is concave. Mesial and distal marginal ridges border the concavity, the lingual portion of the incisal ridge, and the convexity apically to the cingulum.Jan 9, 2015.

Central incisors are the two upper and lower teeth at the very front of the mouth. On either side of them are the lateral incisors, making eight incisors in total in the adult dentition.
For example - You are identifying a maxillary incisor from the labial surface. And your right incisal angle is sharper than your left or your left outline of the crown is more convex than your right or your left incisal angle is not so sharp or more convex, the given tooth is your right maxillary incisor.
This difference is most pronounced on anterior teeth. The amount of curvature of the cervical line on the mesial of the maxillary central incisor is larger than for any other tooth, extending incisally one fourth or more of the crown length (Fig. 2-16), whereas the distal cervical line curves less.
As you know, the two maxillary central incisors are part of the maxillary dental arcade, either side of the midline. They are the most prominent teeth, having a rectangular or square shape. Each maxillary central incisors measures approximately 22.5 mm in length, half of which (10-11 mm) represents the crown.

Lingual Surface
In contrast to the smooth labial surface, the lingual surface is full of convexities and concavities. In addition
Mesial Surface
The mesial aspect of the maxillary central incisors is triangular. The base is located at the cervix and the apex at the incisal ridge
Distal Surface
The crown outlines present on the distal surface are almost identical to the ones on the mesial surface
Incisal Surface
The crown of the maxillary central incisors appear bulkier when viewed from the incisal surface
Internal Structure
Thepulp chamberof the maxillary central incisors is located equidistant from the walls, within the centre of the crown
Dental anatomy central incisor
Front teeth of most mammals
Incisors are the front teeth present in most mammals. They are located in the premaxilla above and on the mandible below. Humans have a total of eight. Opossums have 18, whereas armadillos have none.
The mandibular central incisor is the tooth located on the jaw
The mandibular central incisor is the tooth located on the jaw, adjacent to the midline of the face. It is mesial from both mandibular lateral incisors. As with all incisors, its function includes shearing or cutting food during mastication, commonly known as chewing. There are no cusps on the tooth. Instead, the surface area of the tooth used in eating is called an incisal ridge or incisal edge. Though the two are similar, there are some minor differences between the deciduous (baby) mandibular central incisor and that of the permanent mandibular central incisor. The mandibular central incisors are usually the first teeth to appear in the mouth, typically around the age of 6–8 months.
The mandibular lateral incisor is the tooth located distally from
The mandibular lateral incisor is the tooth located distally from both mandibular central incisors of the mouth and mesially from both mandibular canines. As with all incisors, their function is for shearing or cutting food during mastication, commonly known as chewing. There are no cusps on the teeth. Instead, the surface area of the tooth used in eating is called an incisal ridge or incisal edge. Though relatively the same, there are some minor differences between the deciduous (baby) mandibular lateral incisor and that of the permanent mandibular lateral incisor.

Tooth
The maxillary central incisor is a human tooth in the front upper jaw, or maxilla, and is usually the most visible of all teeth in the mouth. It is located mesial to the maxillary lateral incisor. As with all incisors, their function is for shearing or cutting food during mastication (chewing). There is typically a single cusp on each tooth, called an incisal ridge or incisal edge. Formation of these teeth begins at 14 weeks in utero for the deciduous (baby) set and 3–4 months of age for the permanent set.
The maxillary lateral incisors are a pair of upper (
The maxillary lateral incisors are a pair of upper (maxillary) teeth that are located laterally from both maxillary central incisors of the mouth and medially from both maxillary canines. As with all incisors, their function is for shearing or cutting food during mastication, commonly known as chewing. There are generally no cusps on the teeth, but the rare condition known as talon cusps are most prevalent on the maxillary lateral incisors. The surface area of the tooth used in eating is called an incisal ridge or incisal edge. Though relatively the same, there are some minor differences between the deciduous (baby) maxillary lateral incisor and that of the permanent maxillary lateral incisor. The maxillary lateral incisors occlude in opposition to the mandibular lateral incisors.
