What type of caries intervention? Brushing, Flossing, Mouth Wash
Non operative intervention
26
What type of caries intervention? Oral prophylaxis and restoration
Operative Intervention
27
Removal of tooth structure for placement of a restoration which should be minimally invasive and conserve as much natural tooth structure as possible
Surgical Management of Caries
28
What are the non surgical management of caries strategies
Physical barriers (Sealants) Biofilm modification Remineralization by means of chemotherapeutic interventions Change in patient behavior
29
Inhibition of caries initiation
Caries prevention
30
Microorganisms or substances that are capable of promoting/initiating dental caries
Cariogenic
31
Describes how cariogenic a microorganism or substance is
Cariogenicity
32
Capable of arresting dental caries / arrest the progression of dental caries
Cariostatic
33
Is dental biofilm and dental plaque the same thing?
Yes
34
Refers to the total loss of enamel and exposure to the underlying dentin
Cavitated
35
Refers to a microorganism that is capable of producing acids
Acidogenic
36
Refers to a microorganism that is capable of thriving in an acidic environment
Aciduric
37
Oldest evidence of caries was seen where?
Broken Hill, Northern Rhodesia (Zambia)
38
What specimen was unearthed from broken hill northern rhodesia (give both names)
Homo Rhodesiensis Cranium (Homo Heidelbergensis)
39
References to caries was found in the writings of which poet?
Homer
40
In the Sargonid Dynasty of Assyria, what was the reason given by the kings physician for the need of a tooth extraction?
Spreading inflammation (infection)
41
Text which mentions tooth worms as the cause of dental caries
Sumerian Texts
42
Manuscript which mentions diseases of teeth
Ebers papyrus
43
The surgeon that wrote that caries is caused by worms
Guy de Chauliac
44
This muslim dentist who stated that tooth worms do not exist
Gaubari
45
He was one of the first people to cite that sugar is a possible cause of cavities
Pierre Fauchard
46
They researched more about plaque and investigated the causes of dental caries
Miller, G.V. Black, J.L. Williams
47
This theory states that there is an imbalance between the humors of the body which causes tooth decay
Humoral Theory
48
This theory states that tooth decay originates from within the tooth like a bone gangrene
Vital Theory
49
He said that dental decay comes from external factors not internal, opposing the vital theory
Parmly
50
He proposed that decay of the tooth is caused by acids which are produces by the fermentation of food particles around the teeth
Robertson
51
This theory states that caries starts as a chemical process but microorganisms continue the process of disintegration
Parasitic (Septic) Theory
52
Described filamentous organisms in the membrane removed from teeth
Erdl
53
Attributed dental caries to "denticolae"
Ficnus
54
They said that dental caries is a chemical process but living organisms continue the disintegration in both enamel and dentin
Leber and Rottenstein
55
They said that bacteria were essential to caries but there is still an exogenous source of the acids
Clark, Tomes, Magitot
56
They presented a septic theory that acid capable of causing decalcification is produced by bacteria that feeds on the organic fibrils of dentin
Underwood and Miller
57
This scientist discovered that several strains of lactobacilli bacteria is linked to dental caries
Fernando E. Rodriguez Vargas
58
This researcher suggested that bacterial strain streptococcus mutans was responsible for cavities
Killian Clarke
59
Their hamster studies showed a direct correlation between bacteria and cavities
R.J. Fitzgerald and Paul Keyes
60
The chemico-parasitic theory (acidogenic theory) was made by?
Willoughby D. Miller
61
What are the 2 stages of chemico-parasitic process in the acidogenic theory
First decalcification of enamel and dentin | Second dissolution of the softened residue
62
What are the factors in the process of decalcification according to Millers acidogenic theory
Oral microorganisms Carbohydrate substrate Acid
63
What are the drawbacks of Millers Acidogenic Theory
Predilection of specific sites on a tooth (there are areas more prone to caries) Initiation of smooth surface caries Some populations are caries free
64
They proposed the proteolytic theory
Gottlieb and Gottlieb
65
This theory states that the organic or protein elements of the tooth are the initial pathways of invasion by microorganisms
Proteolytic Theory
66
In the proteolytic theory, these are mentioned as the pathways for microorganism invasion through the enamel
Enamel lamellae and Enamel rod sheaths
67
Who made the sulfatase theory?
Pincus
68
What are the stages of the sulfatase theory
1st: proteolytic organisms attack the protein elements of the tooth 2nd: sulfuric acid is formed
69
This theory states that caries start in the inner tooth surface then pulp lymph is affected
Phosphate theory of Csernyei
70
Schatz is responsible for what theory?
The proteolysis chelation theory
71
This is a process that involves the complexing of metallic ion to a substance through a covalent bond which results in a highly stable, poorly dissociated or weekly ionized compound
Chelation
72
This theory states that both the enamel and dentin is attacked simultaneously
Proteolysis Chelation Theory
73
What are the drawbacks of the proteolysis chelation theory
Increased caries incidence with increased sugar consumption Decreased caries incidence following the topical or systemic administration of fluoride The cause of dental caries is not only due to the presence of the chelating agent
74
They made the Sucrose Chelation Theory
Egglers - Laura
75
In the sucrose chelation theory, the uptake of PO4 (phosphate) by plaque bacteria occurs when?
Glycolysis and synthesis of polyphosphates
76
This theory states that sucrose itself can cause dissolution of enamel by forming ionized calcium saccharate
Sucrose Chelation Theory
77
This states that all plaque are pathogenic
Nonspecific Plaque hypothesis
78
This states that plaque is pathogenic only if associated with clinical disease
Specific Plaque Hypothesis
79
This states that a certain change in the environment of the residential plaque flora provides pathogenicity to specific species that produce the disease at only specific sites
Ecological Plaque Hypothesis
