What is the water composition in plaque?

The correct response indicates that water makes up approximately 80% of plaque, which highlights the significant role that moisture plays in the overall composition of plaque. This high water content contributes to the adhesive properties of plaque, allowing it to adhere to tooth surfaces more effectively. The moisture in plaque also facilitates the activity of bacteria within it, providing an environment where they can thrive and proliferate. Understanding the composition of plaque, particularly the ratio of water, is essential for dental professionals in managing oral health, as it can influence their approaches to hygiene and treatment. This knowledge can help a dental hygienist explain to patients the importance of regular cleaning to disrupt the bacterial accumulation in plaque, which can lead to oral diseases.
