fundamentals chapter 17

a secondary canal extending canal extending from the pulp to the surface of the root; frequently found near the apex of a root but may occur higher and provide a connection to a perio pocket

production and development of enamel

dentition that begins in utero

primary teeth are being exfoliated and permantent teeth come in 6-12 years old

mineralization begins at birth and continues into adolescenece
toots are complete usually by 3 years after eruption

the tearing away or forcible separation of a structure or part.

an oral habit of grinding, clenching, or clamping the teeth;

conducive to dental caries

used to define a carious lesion

a calcified spherical body composed of cementum, lying free within the pdl, attached to the cementum or imbedded within the cementum

disease of mineralized structures of the teeth characterized by demineralization of the hard components and dissolution of the organic matrix

carious lesion that has become stationary and does not show a tendency to progress further; frequently has a hard surface and takes on a dark brown or reddish-brown color

occures on surfaces not previously affected; also called initial caries; early lesion may be referred to as incipient caries

widespread formation of chalky white areas and incipient lesions that may increase in size over a comparatively short time

occures on a surface adjacent to a restoration; may be a continuation of the original lesion; also called secondary caries

the natural teeth in a dental arch

the permanent teeth that erupt into the positions of exfoliated primary teeth

what pH does cementum demineralize

what pH does enamel demineralize

the pH at which demineralization occures

localized, post-eruptive, pathologic process of external origin involving softening of the hard tooth tissue and proceeding to the formation of cavity

what are the requirements for the development of a cavity (6)

involves one tooth surface

involves two tooth surfaces

involves more than two tooth surfaces

what are the steps of the formation of cavities

what are the three root caries

steps in root caries

clinical recognition of root caries

wearing away of a tooth as a result of tooth-to-tooth contact

what is caused from aggressive brushing

what is caused from to much acid
