Why should a dentist note the type of laser used when sending a biopsy to the lab?

Noting the type of laser used when sending a biopsy to the lab is crucial due to the potential for specific tissue artifacts that can arise from the characteristics of different lasers. Each laser type has its unique interaction with biological tissues, often leading to changes in the tissue structure or cellular morphology. For example, some lasers may cause carbonization or charring at the tissue margins, while others might produce a different thermal effect, impacting how the tissue appears under microscopic examination.

Understanding these effects is vital for pathologists who will evaluate the biopsy. If they are aware of the type of laser used, they can adjust their interpretations based on potential artifacts related to the specific laser system. This knowledge helps in accurate diagnosis, as distinguishing between genuine pathological changes and artifacts caused by laser surgery is essential for providing the best possible patient care.
