What is the composition of dental plaque?
What is the composition of dental plaque?
- Microorganisms floating freely in the mouth, attached to the tooth surface and surrounded by saliva and diet
- Microorganisms forming a loose structure on the tooth surface, surrounded by saliva and diet
- Microorganisms attached to each other and to the tooth surface, embedded, interwoven and surrounded by extracellular material of a triple abiotic origin: bacterial, saliva, and diet (correct)
- Viruses and fungi attached to each other and to the tooth surface, surrounded by bacteria, saliva, and diet
Why is the term 'dental plaque' preferred over 'bacterial plaque'?
Why is the term 'dental plaque' preferred over 'bacterial plaque'?
- Because it includes microorganisms such as viruses, fungi, and protozoa in its content (correct)
- Because it specifies that the plaque is located on the tooth surface
- Because it highlights the importance of saliva and diet in plaque development
- Because it emphasizes the prominent role of bacteria in plaque formation
