What is the water content percentage of plaque by weight?

The correct percentage of water content in dental plaque by weight typically falls between 80-90%. This high water content contributes to the plaque's gel-like characteristics, making it an effective medium for bacteria to thrive. The high moisture level facilitates the growth of microorganisms within the plaque, which can lead to dental issues such as caries and periodontal disease if not adequately managed through oral hygiene practices.

Understanding the water content of plaque is crucial in dental nursing, as it informs both the prevention and treatment strategies for dental diseases. When plaque accumulates, it can lead to a greater risk of tooth decay and gum disease, emphasizing the importance of regular dental cleaning and effective oral hygiene practices.

The percentages in other choices do not accurately reflect the established scientific measurements related to the composition of dental plaque. For instance, options indicating lower water content percentages do not align with the knowledge that plaque is predominantly composed of water, which underscores its role as a habitat for bacteria.
