Dental pad of domestic livestock. Note the lack of upper incisors and canine teeth. The dental pad or browsing pad is a feature of ruminant and camelids [1] dental anatomy that results from a lack of upper incisors and helps them gather large quantities of grass and other plant matter. [2] [3] This feature can be found in ruminants such as ...
Instead of the upper incisors, bovids have a thick and tough layer of tissue, called the dental pad, that provides a surface to grip grasses and foliage. They are hypsodont and selenodont, since the molars and premolars are low-crowned and crescent-shaped cusps. The lower incisors and canines project forward.
The order in which teeth emerge through the gums is known as the dental eruption sequence. Rapidly developing anthropoid primates such as macaques , chimpanzees , and australopithecines have an eruption sequence of M1 I1 I2 M2 P3 P4 C M3, whereas anatomically modern humans have the sequence M1 I1 I2 C P3 P4 M2 M3.
The dental lamina is a band of epithelial tissue which connects the developing tooth bud to the oral epithelium. The dental lamina eventually disintegrates into small clusters of epithelium and is reabsorbed. The dental lamina is first evidence of tooth development and begins at the sixth week in utero.

The retromolar area of a human mandible is covered by the retromolar pad (also known as the piriformis papilla), an elevated triangular area of mucosa.It is composed of non-keratinized loose alveolar tissue covering glandular tissues and muscle fibers. [4]

Dental quadrants The dentition is divided into four quarters. The two dental arches form an oval, which is divided into quadrants which are numbered from 1 to 4: [7] Upper right quadrant: upper right first incisor to upper right wisdom tooth; Upper left quadrant: upper left first incisor to upper left wisdom tooth
