The brain is almost entirely enclosed by the neurocranium with the exception of the foramen magnum and other foramina at the skull base which serve as entry and exit point for blood vessels and cranial nerves. Also, the skull provides support for all of the facial structures. Key facts Function The teeth are the hardest substances in the human body. Besides being essential for chewing, the teeth play an important role in speech. Parts of the teeth include: Surfaces that are nearest the cheeks or lips are referred to as either buccal (when found on posterior teeth nearest the cheeks) or labial (when found on anterior teeth nearest the lips). Those nearest the tongue are known as lingual. Lingual surfaces can also be described as palatal when found on maxillary teeth beside the hard palate. Humans usually have 20 primary (deciduous, "baby" or "milk") teeth and 32 permanent (adult) teeth. Teeth are classified as incisors, canines, premolars (also called bicuspids), and molars. Incisors are primarily used for cutting, canines are for tearing, and molars serve for grinding. Openings: foramen magnum, internal acoustic meatus, jugular foramen, anterior condylar (hypoglossal) canalMain article: Human tooth development Radiograph of lower right (from left to right) third, second, and first molars in different stages of development. Panoramic x-ray radiography of the teeth of a 64-year-old male. Dental work performed mostly in UK/Europe in last half of 20th Century The maxillary central incisors are usually the most visible teeth, since they are the top center two teeth in the front of a mouth, and they are located mesial to the maxillary lateral incisor. The overall length of the deciduous maxillary central incisor is 16mm on average, with the crown being 6mm and the root being 10mm. [17] In comparison to the permanent maxillary central incisor, the ratio of the root length to the crown length is greater in the deciduous tooth. The diameter of the crown mesiodistally is greater than the length cervicoincisally, which makes the tooth appear wider rather than taller from a labial viewpoint. Most dogs have the same number of teeth. However, they will have a different number of adult teeth compared to a puppy. Puppies will usually have a total of 28 teeth when all of their milk teeth have grown. That’s 14 in their upper jaw and 14 in their lower jaw. Microdontia of a single tooth is more likely to occur in a maxillary lateral incisor. The second most likely tooth to have microdontia are third molars. Macrodontia of all the teeth is known to occur in pituitary gigantism and pineal hyperplasia. It may also occur on one side of the face in cases of hemifacial hyperplasia.

Minerva Stomatol (Review). 59 (1–2): 33–43. PMID 20212408.This article will discuss adult and child dentition, different tooth types, basic tooth cross-sectional and surface anatomy, and the various methods of dental notation. Relevant clinical considerations are discussed throughout the article. Humans, like most other mammals, are diphyodont, meaning that they develop two sets of teeth. The first set, deciduous teeth, also called "primary teeth", "baby teeth", or "milk teeth", normally eventually contains 20 teeth. Primary teeth typically start to appear (" erupt") around six months of age and this may be distracting and/or painful for the infant. However, some babies are born with one or more visible teeth, known as neonatal teeth or "natal teeth". a b Ash, Major M. and Stanley J. Nelson.

Dentin: A layer underlying the enamel. It is a hard tissue that contains microscopic tubes. When the enamel is damaged, heat or cold can enter the tooth through these paths and cause sensitivity or pain.
