What is the first step for biopsy specimens removed with a dental laser?

The first step for biopsy specimens removed with a dental laser is to fix them in formalin. This process is crucial because fixation preserves the cellular architecture and prevents degradation of the tissue sample prior to processing. Formalin essentially stabilizes the proteins in the tissues, making them easier to analyze when they are sent for histological examination.

Once the tissue has been fixed properly, it can then be evaluated by an oral pathologist and subsequently processed, which might include dehydration and mounting with proper orientation. However, fixation in formalin must occur first to ensure that the tissue remains intact and suitable for further analysis.
