A tooth which is away from the midline, such as lateral incisor, [1] or the sides of a tooth. [6] Lingual The side of a tooth adjacent to (or the direction toward) the tongue (lingua, compare linguistics and language), as opposed to buccal, labial, or vestibular which refer to the side of a tooth adjacent to (or the direction toward) the inside ...
It is widely accepted that there is a factor within the tissues of the first branchial arch that is necessary for the development of teeth. [2] The tooth bud (sometimes called the tooth germ) is an aggregation of cells that eventually forms a tooth and is organized into three parts: the enamel organ, the dental papilla and the dental follicle. [3]
As a result, the mesial and distal sides of the tooth are further away on the labial side than on the lingual side. Furthermore, a cross-section of the tooth at the cervical line would show a general triangle appearance. One of the triangle's sides would be the facial surface, and the other two sides would be the mesial side and the slightly ...
maxillary lateral incisor (upper jaw, beside the maxillary central incisor) mandibular central incisor (lower jaw, closest to the center of the lips) mandibular lateral incisor (lower jaw, beside the mandibular central incisor) Children with a full set of deciduous teeth (primary teeth) also have eight incisors, named the same way as in ...
In the universal numbering system, one number is used to identify the tooth. The right permanent maxillary first molar is known as tooth "3", and the left permanent maxillary first molar is known as tooth "14". In the Palmer notation, a number and symbol are used to identify the tooth. The number identifies the tooth position relative to the ...
The distal and mesial marginal ridges are evident and the cingulum is prominent. [13] The lingual fossa is more concave than the central incisor. [13] The cingulum will often have a deep developmental groove on the distal side that can continue well into the root. [13] The lingual view of the lateral incisor fits into the geometric shape of a ...
A broken upper front tooth showing the pink of the pulp. Tooth abnormalities may be categorized according to whether they have environmental or developmental causes. [58] While environmental abnormalities may appear to have an obvious cause, there may not appear to be any known cause for some developmental abnormalities.
The dental arches are the two arches (crescent arrangements) of teeth, one on each jaw, that together constitute the dentition.In humans and many other species, the superior (maxillary or upper) dental arch is a little larger than the inferior (mandibular or lower) arch, so that in the normal condition the teeth in the maxilla (upper jaw) slightly overlap those of the mandible (lower jaw) both ...
