How Much Do You Know About Disrupting Oral Biofilm?

Biofilms are composed of bacteria adhering to each other or to living or nonliving surfaces. They form complex communities surrounded by extracellular polymeric substances. Cells within these biofilms have changing physiologic and metabolic properties that contribute to their persistence. Take our quiz to test your knowledge on disrupting oral biofilm.


If not removed regularly, a complex and mature biofilm develops, containing up to how many bacterial species at a single site?

Correct! Wrong!

Oral biofilm exposed to an excess of carbohydrates contains mainly Gram-positive carbohydrate-fermenting bacteria that may cause demineralization, caries, pulpitis, and periodontitis.
