Lesson 5.1: Oral Microbiology and Plaque-Associated Diseases

Front

What is periodontal disease?

Back

Periodontal disease refers to inflammation and infection of the gums and supporting structures of the teeth.

Front

What are mutans streptococci?

Back

Mutans streptococci are a group of bacteria that are the most caries-conducive bacteria in the mouth.

Front

What term describes species that contribute to disease processes in periodontal diseases?

Back

Periodontopathogens.

Front

What are the four factors necessary for caries to occur?

Back

Bacteria, sugar, time, and a susceptible tooth surface.

Front

What is periodontitis?

Back

Periodontitis is an infection that can occur when members of the normal oral flora invade tissues.

Front

What is the role of bacteria in dental caries?

Back

Bacteria metabolize sugars to produce acids that demineralize tooth enamel, leading to caries.

Front

What is gingivitis?

Back

Gingivitis is the inflammation of the gums, often a precursor to periodontal disease.

Front

What is the significance of oral flora?

Back

Oral flora consists of microorganisms that normally inhabit the mouth and can contribute to health or disease.

Front

How does sugar contribute to dental caries?

Back

Sugar serves as a food source for bacteria, which produce acids that damage tooth enamel.

Front

What is the relationship between time and caries development?

Back

The longer bacteria and sugars are present on tooth surfaces, the greater the risk of caries development.
