What does a "smear biopsy" refer to in dental diagnostics?

A "smear biopsy" refers specifically to exfoliative cytology, which involves collecting cells from the surface of a lesion or tissue without the need for invasive procedures. This technique is useful in dental diagnostics to evaluate cellular changes, detect abnormal cells, and assist in diagnosing conditions such as oral cancers or other mucosal diseases.

In exfoliative cytology, cells are typically obtained with a brush or a swab and are then spread onto a microscope slide for examination. This method is valuable because it is relatively quick, minimally invasive, and can provide immediate insights into the cellular characteristics of the lesion being examined.

Understanding this technique in the context of dental diagnostics highlights its importance in early detection and monitoring of pathological changes in the oral cavity, making it an essential tool in preventive dental care.
