CAMBRA

Caries management by risk assessment.

Caries

Tooth Decay
Infectious & communicable disease.

Caries Risk Test ( CRT)

Test for carogenic bacteria.

Cariology

The science & study of dental caries.

Carious lesions

White spots, brown spots, decay on tooth surfaces.

Cavitation

Formation of cavity or hole.

Demineralization

Loss of minerals from the tooth.

Fermentable carbohydrates

Sucrose
Fructose
Lactose
Glucose

Flouride

Mineral used in dental products to make teeth more resistant to decay.

Incipient caries

Tooth decay that is beginning to form or become apparent.

Lactobacilli

Bacteria that produce lactic acid from carbohydrates.

Mutans streptococci

Type of bacteria primarily responsible for caries.

What two type of bacteria is responsible dental caries???

Lactobacilli (LB)
Mutans streptococci (MS)

Lactobacilli

High sugar intake

Mutans streptococci

Major pathogenic (disease producing) bacteria found in dental plaque.

Carious lesions can occur in four general areas of the tooth.

1. Pit & fissure caries
2. Smooth surface caries
3. Root surface caries
4. Secondary (recurrent) caries

Pit & fissure caries

On occlusal surfaces, on buccal & lingual grooves of posterior teeth, & on lingual pits of the maxillary incisors.

Pellicle

Micro-colonies of bacteria embodied in an adhesive substance.
Thin film coating of salivary.

Plaque

Soft deposit of teeth that consists of bacteria & bacterial by-products.

Rampant caries

Develops rapidly & is widespread throughout the mouth.

Remineralization

Replacement of minerals in the tooth.

Saliva rate flow test

Determines flow rate of saliva in millimeters per minute.

Xerostomia

Dryness of the mouth.

Xylitol

Ingredient in chewing gum that has an antibacterial effect against decay-causing bacteria.

_____ is the most highly mineralized tissue in the body.

Enamel

What is the mineral in the enamel that makes the crystal easier to dissolve???

Carbonated apatite

What are the three factors for caries to develop???

1. A susceptible tooth
2. a rich diet in fermentable carbohydrates
3. Specific bacteria

Smooth surface caries

On enamel surfaces, including mesial, distal, facial, & lingual surfaces.

Root surface caries

On any surface of the exposed root.

Secondary (recurrent) caries

Form in the small spaces & gaps.
Between the tooth.
Margins of the restoration.

Carious lesions develop in two stages:

1. Incipient caries
2. Cavitation

Early childhood caries affects ___ of preschool children.

One third

True/False
Early childhood caries is more common among children with special needs.

True

What are the risk factors for Early childhood caries???

Low-income families
Particular ethnic groups
Limited access to care
Lack of water flouridation

What is another term for Early Childhood Caries???

Baby bottle tooth decay

What three protective mechanisms are produced by saliva???

Physical protection
Chemical protection
Antibacterial protection

What can plaque cause???

The bacteria in plaque is fed by the sugar foods we eat.
The bacteria rich plaque converts sugars into acid.
The acid attacks the tooth & causes demineralization.

Baby Bottle Syndrome

Extensive dental decay caused by putting small children to bed with a bottle of milk, juice or any liquid other than water.

How dental decay occurs???

Plaque/bacteria
Carbohydrates
Tooth structure

What help prevent the process of secondary caries???

Bonding the restoration at the prepared tooth.
Dental material that slowly release flouride.

Plaque + sugar/ carbohydrates =

Acids

Acids + tooth =

Decay

Bacteria + carbohydrates/food =

Acids

Acids + susceptible tooth structure =

Decay
