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 ...

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.
It is called preauricular sinus which, according to the U.S. National Institutes of Health, or NIH, "generally appears as a tiny skin-lined hole or pit, often just in front of the upper ear where ...
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 ...
