Dental Plaque and Oral Health

The video tutorial covers the nature and formation of dental plaque, its bacterial composition, and the process of biofilm maturation. It explains how plaque can lead to tooth decay and transform into calculus if not properly managed. The tutorial also discusses methods for detecting and controlling plaque, including physical removal and chemical treatments like chlorhexidine. Additionally, it touches on the potential for vaccination against dental caries and concludes with the importance of maintaining oral hygiene.

What is the primary composition of dental plaque?

• A mix of bacteria and fungi

• Only bacteria

• Mostly fungi with some bacteria

• Mostly bacteria with some fungi

Which bacteria is primarily involved in the formation of dental plaque?

• Actinomyces

• Streptococcus salivarius

• Streptococcus mutans

• Lactobacillus

What is the main difference between supragingival and subgingival biofilms?

• Both contain only aerobic bacteria

• Subgingival biofilms contain aerobic bacteria

• Supragingival biofilms contain anaerobic bacteria

• Supragingival biofilms contain aerobic bacteria

How can dental plaque be detected?

• Using X-rays

• Through disclosing agents and tactile detection

• Using a microscope

• By tasting the plaque

What happens when plaque is not removed and turns into calculus?

• It hardens and can cause periodontal complications

• It leads to tooth whitening

• It becomes softer

• It can be easily brushed away

What is the role of Streptococcus mutans in tooth decay?

• It prevents tooth decay

• It produces acid that leads to decay

• It strengthens the enamel

• It neutralizes acids

What is the most effective way to control dental plaque?

• Using mouthwash only

• Flossing alone

• A combination of brushing, rinsing, and professional cleaning

• Brushing alone

Why is chlorhexidine used in dental care?

• To whiten teeth

• To remove calculus

• To act as a bactericidal and fungicidal antiseptic

• To strengthen gums

What is a major challenge in developing a vaccine against dental caries?

• Lack of research

• Difficulty in targeting specific bacteria

• Lack of interest in dental health

• High cost of production

What is the recommended frequency for professional teeth cleaning?

• Once a month

• Twice a year

• Once a year

• Every two years
