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]
Teeth are depicted in left lateral view (left side and center of the image) or occlusal view (right side of the image). The positions of tooth features are described along four directions: mesial (forwards, towards the chin), distal (backwards, towards the jaw joint), lingual (inwards, towards the tongue), and buccal or labial (outwards ...
The tooth bud (sometimes called the tooth germ) is an aggregation of cells that eventually forms a tooth. It is organized into three parts: the enamel organ, the dental papilla and the dental follicle. [27] The enamel organ is composed of the outer enamel epithelium, inner enamel epithelium, stellate reticulum and stratum intermedium. [27]
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 occlusal surface has four grooves. The central groove is not straight but runs down the center of the tooth mesially to distally and contains four pits (mesial, central, central, and distal). The distobuccal groove runs from the distal pit in the central groove distobuccally separating the distal and distobuccal cusps.
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).
In contrast, the left mandibular teeth move medially, downwards and anteriorly across their opposing posteriors and this is called the non-working side (the side to which the mandible is moving away from). Retrusive movements: This is when the mandible moves posteriorly from ICP. Compared with protrusive and lateral movements, retrusive ...
