Children with a full set of deciduous teeth (primary teeth) also have eight incisors, named the same way as in permanent teeth.

As such, they are considered part of the human digestive system. [1] Humans have four types of teeth: incisors, canines, premolars, and molars, which each have a specific function.

Close up front view. Contact with adjacent teeth in the same arch is referred to as interproximal contacts. The maxillary central incisors are one of only two types of teeth which has an interproximal contact with itself. The other type of teeth is the mandibular central incisors.
Mesiodens: Mesiodens is an extra tooth that grows behind the front teeth. A mesiodens may push the front teeth apart to make room for itself thus creating a gap between the front teeth. [3] 4. Skeletal discrepancy: Dental skeletal discrepancy can be a cause behind gap teeth. If the upper jaw grows more than the lower jaw, teeth on the upper jaw ...
Succedaneous would refer to these teeth as a group. Further, the name depends upon which arch the tooth is found in. The term, "maxillary", is given to teeth in the upper jaw and "mandibular" to those in the lower jaw. There are four classes of teeth: incisors, canines, premolars, and molars. Premolars are found only in permanent teeth; there ...
It was theorized that positive selection for shovel-shaped incisors over the spatulate incisors is more commonly found within cultures that used their teeth as tools due to a greater structural strength in increased shovel-shaped incisors. [2] In some instances, incisors can present a more pronounced version of this called double shovel-shaped.
The red arrow is directly buccal to the right first maxillary molar, and the name label for the patient (Martin) is embedded in the resin directly palatal to the same tooth. Midline Main article: Dental midline. Roughly, an imaginary vertical line dividing the left and right sides of the mouth at the teeth. Occlusal
An African elephant in Tanzania, with visible tusks. Tusks are elongated, continuously growing front teeth that protrude well beyond the mouth of certain mammal species. They are most commonly canine teeth, as with narwhals, chevrotains, musk deer, water deer, muntjac, pigs, peccaries, hippopotamuses and walruses, or, in the case of elephants, elongated incisors.
