After plaque accumulate on the tooth and colonizes what happens



After plaque accumulate on the tooth and colonizes what happens:

  • A. Proliferation.
  • B. Maturation.

The correct answer is: B. Maturation.

Here's why:

- Plaque accumulation:

Bacteria in your mouth adhere to the tooth surface, forming a thin film called the pellicle.

- Initial colonization:

Specific bacteria, mainly Streptococcus mutans, start to colonize the pellicle and multiply rapidly (proliferation).

- Maturation:

As more bacteria join the colony, they diversify, forming a complex biofilm with different layers and structures. This process involves further proliferation of specific bacteria suited to different niches within the biofilm.

- Consequences:

The mature biofilm produces acids from sugars, leading to demineralization of the tooth enamel and potentially causing cavities (dental caries). It can also contribute to gum inflammation (gingivitis) and periodontal disease.

Therefore, both proliferation and maturation are crucial steps in the development of dental plaque and its associated consequences.
