What is the difference between maxillary central incisor and maxillary lateral incisor?
Maxillary. Central incisors are larger than lateral incisors in both permanent and deciduous dentition. Viewed from the buccal aspect, the incisal (cutting) edge of central incisors are straight, whereas the incisal edge of lateral incisors slope toward the distal side, giving them a shorter distal crown height.
Which tooth is the central incisor?
There are two types of incisors: Central incisors are those in the very front and center of the jaw, known as the mesial position. The largest incisors are the maxillary central (top and center) incisors. They are the most prominent teeth visible when a person smiles.
Which teeth are maxillary incisors?
The maxillary central incisors are the two teeth which are adjacent to the midline in the maxillary arch. They share a mesial contact with each other and have a distal contact with the lateral incisors.
How long is a maxillary central incisor?
Maxillary central incisors vary in root length with reported average length of 22mm to 23.8mm6-8.
How many canals are there in maxillary central incisor?
The internal anatomy of the maxillary central incisor is well-known and usually presents one root canal system.
What is central incisors?

How many central incisors are there?
two central incisors
In each arch there are two central incisors, two lateral incisors, two canines, four premolars, and six molars.
What is the difference between maxillary and mandibular incisors?
Maxillary Incisors are larger than Mandibular Incisors. Maxillary incisors have wider Mesio-Distal diameter than Labio-Lingual Diameter. Mandibular Incisors have wider Labio-lingual Diameter than Mesio-Distal diameter. Maxillary Incisors have more distinct lingual Anatomy.
What is the function of maxillary teeth?
Since it houses the upper teeth and forms a portion of the jaw, the maxilla is necessary for the process of mastication (chewing) and speaking.
How many roots do central incisors have?
Different types of teeth have a different number of roots and root formations. Typically incisors, canines and premolars will have one root whereas molars will have two or three.
How wide is a central incisor?
The average width of a natural maxillary central incisor is 8.92 mm. This value is determined from the results of three studies of natural dentitions. The average width of a mandibular central incisor is 5.5 mm.
Which teeth do the most chewing?
Molars are the teeth that do most of the chewing, because those flat surfaces are perfect for grinding and crushing food until it’s ready to be swallowed.
What is a maxillary lateral incisor?
The maxillary lateral incisors are a pair of upper (maxillary) teeth that are located laterally (away from the midline of the face) from both maxillary central incisors of the mouth and medially (toward the midline of the face) from both maxillary canines.
