Study These Flashcards
A

cariogenicity

25
difference between dental plaque and dental biofilm
dental plaque is a clinical term
26
what is dental biofilm?
consortium of microorganisms that are stuck on the tooth surface
27
what is a caries lesion?
Clinical manifestation of caries diseases
28
Non cavitated lesions are characterized by (3)
Change in color Glossiness Surface structure
29
What are the 4 periods that dental caries were present in?
Neolithic Bronze Iron Medieval
30
What is the oldest evidence of caries? (date, place and name of craniums)
1921 Broken hill, Northern Rhodesia (Zambia) Zinc mine Homo Rhodesiensis cranium which is an African version of Homo Heidelbergensis
31
What are the early writings about dental caries? (5)
``` Sumerian text Homer Ebers papyrus Sargonid dynasty of Assyria Guy de chauliac ```
32
What are the 4 early theories on causes of dental caries?
Legend of worms Endogenous theories Chemical theory Parasitic theory
33
What are the 4 body humors?
Yellow and black bile Blood Phlegm
34
This was the first person to reject the worm theory?
Gaubari
35
Who are under the early studies? Give their contributions. (3)
Pierre Fauchard - Father of modern dentistry and stated sugar is a possible cause of cavities Willoughby D. Miller - First oral microbiologist and microorganisms caused caries Miller and G.V. black and J.L. Williams - researched about plaque and investigated the causes of dental caries
36
What are the endogenous theories?
Humoral theory | Vital theory
37
Explain the Vital theory
This basically states that caries starts from within the tooth like a bone gangrene
38
This person talked about an unidentified chymal agent is responsible for caries
Parmly
39
Robertson prosed that dental decay was caused by?
Acid formed by the fermentation of food particles around the teeth
40
He described that there were filamentous organisms in the membrane of teeth
Erdl
41
Who talked about Denticolae?
Ficnus
42
They stated that living microorgranisms continued the disintegration in both enamel and dentin
Leber and Rottenstein
43
They stated that bacteria were essential to caries but acids came from an exogenous source
Clark, Tomes and Magitot
44
they presented a septic theory
Underwood and Miller
45
Discovered different strains of lactobacilli
Fernando E. Rodriguez Vargas
46
Killian clarke discoverd?
Bacterial strains streptococcus mutans caused cavities
47
Hamster studies by ________ & ________ showed the direct correlation of bacteria and cavities
R.J. Fitzgerald and Paul Keyes
48
What are the 2 steps of the chemo-parasitic theory?
Decalcification of enamel and dentin | Dissolution of the softened residue
49
Who proposed the chemo-parasitic theory?
Willoughby D. Miller
50
What are the 3 factors according to chemo-parasitic theory?
Oral microorganisms Carbohydrate substrates Acids
51
What are the drawbacks of the acidogenic theory? (3)
Predilection of specific sites on the tooth Initiation of smooth surface caries Some populations are caries free
52
The theory that the Gottlieb and Gottlieb proposed?
Proteolytic theory
53
Proteolytic theory states that it destroys the ____________ matter first then the decalcification of the hard tissues
organic
54
what are the pathways for microorgranism invasion through the enamel?
Enamel lamellae and/or enamel rod sheaths
55
Drawbacks of the proteolytic theory
No sufficient evidences | Caries still occurred even in absence of proteolytic microorganisms
