An oral biopsy is a medical procedure that involves the removal of a small tissue sample from the mouth or oral cavity to examine it under a microscope. The procedure is typically performed to diagnose and confirm the presence of oral diseases or conditions, such as oral cancer, precancerous lesions, infections, inflammatory conditions, and autoimmune disorders.
During an oral biopsy, a small area of the tissue is numbed with a local anesthetic, and then a small piece of the tissue is removed using a scalpel or a biopsy punch. The tissue sample is then sent to a laboratory for analysis by a pathologist, who will examine it under a microscope to determine the presence or absence of abnormal cells or tissues.
Oral biopsies are relatively quick and safe procedures and can be performed in a dental office or an outpatient setting. They are generally recommended when there is a suspicion of oral cancer or other potentially serious conditions, or when other diagnostic tests have been inconclusive.
