The premolars, also called premolar teeth, or bicuspids, are transitional teeth located between the canine and molar teeth. In humans, there are two premolars per quadrant in the permanent set of teeth, making eight premolars total in the mouth. [1][2][3] They have at least two cusps. Premolars can be considered transitional teeth during ...
Humans have four types of teeth: incisors, canines, premolars, and molars, which each have a specific function. The incisors cut the food, the canines tear the food and the molars and premolars crush the food. The roots of teeth are embedded in the maxilla (upper jaw) or the mandible (lower jaw) and are covered by gums.
Dental anatomy is a field of anatomy dedicated to the study of human tooth structures. The development, appearance, and classification of teeth fall within its purview. (The function of teeth as they contact one another falls elsewhere, under dental occlusion.) Tooth formation begins before birth, and the teeth's eventual morphology is dictated ...
The inferior alveolar nerve (IAN) (also the inferior dental nerve) is a sensory [1] [contradictory] branch of the mandibular nerve (CN V 3) (which is itself the third branch of the trigeminal nerve (CN V)). The nerve provides sensory innervation to the lower/mandibular teeth and their corresponding gingiva as well as a small area of the face ...
Tooth decay in primary teeth tends to progress quite quickly and often reaches the pulp of the tooth. In cases of extensive tooth decay, the pulp must be treated to maintain the health of the tooth and its supporting tissues. In pulp therapy, areas of decay and infected pulp tissue are removed, then the pulp is sealed with medicaments. [5]
Covered California is the health insurance marketplace in the U.S. state of California established under the federal Patient Protection and Affordable Care Act (ACA).

The state increased the payment rate for evaluating a child's teeth, for example, from $15 to $45, and up to $100 if a dentist sees the same child two years in a row, according to the California ...
The mandibular first premolar is the tooth located laterally (away from the midline of the face) from both the mandibular canines of the mouth but mesial (toward the midline of the face) from both mandibular second premolars. The function of this premolar is similar to that of canines in regard to tearing being the principal action during ...
