What is the appearance of pellicle on the teeth?

The appearance of pellicle on the teeth is characterized by a thin clear film. Pellicle is a proteinaceous layer that forms on the enamel surface almost immediately after the teeth are cleaned. It is derived from saliva and serves as a protective barrier for the enamel, as well as a substrate for the attachment of bacteria and plaque development.

This thin and transparent film can often go unnoticed by patients and dental professionals unless specific diagnostic techniques, such as disclosing agents, are utilized to visualize it. Pellicle plays a significant role in oral health, influencing the formation of biofilm and dental plaque.

Other appearances mentioned, such as a thick white layer, dark stain, or rough surface, do not accurately represent pellicle. A thick white layer typically refers to plaque accumulation rather than pellicle, while dark stains can be due to dietary factors or tobacco use, and a rough surface may indicate the presence of calculus or advanced plaque accumulation.
