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]
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 ...

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 ...
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 ...
Among deciduous (primary) teeth, ten are found in the maxilla (upper jaw) and ten in the mandible (lower jaw), for a total of 20. The dental formula for primary teeth in humans is 2.1.0.2 2.1.0.2. In the primary set of teeth, in addition to the canines there are two types of incisors—centrals and laterals—and two types of molars—first and ...
It refers to the portion of the teeth that forms a convex protuberance at the cervical third of the anatomic crown. It represents the lingual or palatal developmental lobe of these teeth. [1] In zoology and palaeontology, cingulum refers to this feature only in the upper teeth. When this occurs in the lower teeth it is called the cingulid.
The hypocone is found on the distal lingual side of the tooth. It fits into the grooves of the lower dentition and is an adaptation for the overall grinding and tearing of foods using the occlusal (chewing side) of the tooth surface during occlusion or mastication (chewing).
