Dental Caries by Mind Map: Dental Caries

1. Acc to stage

1.1. Spot caries

1.2. Enamel caries

1.3. Dentin Caries

1.4. Deep dentin Caries

2. Definition:.

2.1. Localized,bacterial,multi-factorial&dynamic disease resulting from imbalance between demineralization&remineralization processes leading to net mineral loss over time

3. Etiology

3.1. Host Factors

3.1.1. susceptible tooth exposed in the mouth

3.1.2. Saliva Xerostomia Viscous saliva Decrease in buffers Anti-bacterial effect

3.2. CHOs

3.2.1. Disaccharides>monosaccharides> polysaccharides CHO intake>>inc in caries incidence Texture: sticky CHO>> more cariogenic Refined CHO>> more cariogenic

3.3. Cariogenic bacteria

3.3.1. Streptococcus mutans

3.3.2. Lactobacilli

3.3.3. Intake frequency >>inc in caries incidence

3.4. Time

4. Types

4.1. Acc to site

4.1.1. Pits&fissure

4.1.2. Smooth surface

4.1.3. Root surface

4.2. Acc to progression rate

4.2.1. Rampant

4.2.2. Acute

4.2.3. Chronic

4.2.4. Arrested

5. Theories of dental caries

5.1. Acidogenic theory >> most acceptable one

5.2. Proteolytic theory

5.3. Proteolysis chelation theory

6. Caries balance

6.1. Demineralization

6.2. Remineralization

7. Experiments concerning caries & its etiologic factors

7.1. Turku Study stated that sucrose is highly cariogenic>fructose...xylitol is non-cariogenic

7.2. Vipeholm experiment concluded that frequency&texture of CHO are more effective on caries activity (inc in intake amount&frequency&sticky CHO>>inc in caries activity)

7.3. Hopewood House experiment reported that children with low CHO diet showed low caries incidence & vice versa

7.4. Miller reported that bacteria produced acids causing tooth decay.Then, Orland concluded that not all bacteria are cariogenic & Streptococcus mutans > cariogenic than lactobacilli

7.5. Stephan concluded that enamel demineralization occurs at critical PH 5.5,then remineralization occurs with increase in PH

8. Salma Saeed Abd EL-Naby Shehata 186 section 10

9. Dental plaque

9.1. Composition

9.1.1. Bulk of micro-organisms

9.1.2. Amorphous matrix of proteins,CHO,Ca,P&F

9.2. Formation mechanism

9.2.1. Formation of an acquired enamel pellicle

9.2.2. Bacterial colonization of the pellicle Pioneer community Intermediate community Mature community
