flil the maxillary central incisors, it is often the result of a pronounced labial frenum.

A space, or lack of contact area, between any two teeth in the same arch is called a
flil flil flil flil flil flil flil flil flil flil flil flil flil flil flil flil flil
diastema. When a diastema occurs between the maxillary central incisors, it is often the
flil flil flil flil flil flil flil flil flil flil flil flil flil flil
result of a pronounced labial frenum extending to the crest of the alveolar ridge and
flil flil flil flil flil flil flil flil flil flil flil flil flil flil flil
possibly over the ridge. This band of firm connective tissue causes the erupting incisors
flil flil flil flil flil flil flil flil flil flil flil flil flil flil
to be pushed aside resulting in a diastema, or space. Correction of a diastema usually
flil flil flil flil flil flil flil flil flil flil flil flil flil flil flil
involves surgical removal, or cutting, of the frenal tissue between teeth.

Torus palatinus is excess bone growth and occurs in the midline of the hard palate. It
flil flil flil flil flil flil flil flil flil flil flil flil flil flil flil
may grow to varying sizes and is generally only a problem when the construction of a
flil flil flil flil flil flil flil flil flil flil flil flil flil flil flil flil
maxillary denture is necessary. In health, such bony protuberances, or excess bone
flil flil flil flil flil flil flil flil flil flil flil flil
growths, do not occur on the soft palate, alveolar ridge, or oral pharynx.

Contraction of the mylohyoid muscle raises the tongue. The palatopharyngeal muscle and the flil flil flil flil flil flil flil flil flil flil flil flil
palatoglossal muscle form the posterolateral borders of the oral cavity. There is not a

The oral vestibule is the space or potential space that exists between the lips or cheeks
flil flil flil flil flil flil flil flil flil flil flil flil flil flil flil
and teeth. In an edentulous person, the vestibule would extend between the lips or cheeks
flil flil flil flil flil flil flil flil flil flil flil flil flil flil flil
and the alveolar ridges. The oral cavity proper is surrounded by teeth or alveolar ridges
flil flil flil flil flil flil flil flil flil flil flil flil flil flil flil
and extends all the way back to the palatine tonsils. This includes the region from the
flil flil flil flil flil flil flil flil flil flil flil flil flil flil flil flil
floor of the mouth upward to the hard and soft palates.

incisive papilla, which is located on the hard palate. Note that the incisive papilla is a

The laryngeal pharynx is located below the oral pharynx and cannot be seen while

examining the oral cavity. The fovea palatinae, the tonsillar pillars, and the sublingual
flil flil flil flil flil flil flil flil flil flil flil flil flil
fold can be seen when examining the oral cavity. Fovea palatinae are small depressions

in mucosa on either side of the posterior nasal spine indicating the junction of the hard
flil flil flil flil flil flil flil flil flil flil flil flil flil flil flil flil
and soft palate. Tonsillar pillars are folds of tissue that partially surround the tonsils. The
