Biopsy refers to the removal of living tissue from the site of lesion for the purpose of microscopic examination of that part and to reach a confirm diagnosis. Biopsy procedure helps in the treatment plan. It not only helps in the diagnosis but also serves as a treatment option for smaller lesions of the oral cavity by excising. If a patient is told by his dentist that oral biopsy is to be done for any oral lesion present in his mouth, it doesn’t mean that there is some malignant or cancerous condition present. Biopsy is just a diagnostic test which will further help the dentist in treatment planning.

Excisional Biopsy for Oral Lesions:
Incision in elliptic manner in Excisional Biopsy. Normal tissue is also removed along with the lesion.
Section of the tissue can be taken from the scalpel, cautery or high frequency cutting knife or lasers. Scalpel is the instrument of choice as it cleanly removes the tissue and doesn’t dehydrate as cautery or high frequency cutting knife. Cautery and high frequency cutting knife is of great value in dealing with vascular lesions where it controls the bleeding at the biopsy site.
Frozen Section Biopsy for Oral Lesions:
Punch Biopsy for Oral Lesions:

Brush Biopsy is used to detect oral cancer. Spots and lesions on lips, throat, tongue and gums are evaluated. Brush biopsy test is very convenient for dentist and the patient. No anesthesia is required for the procedure. With a soft nylon brush, transepithelial biopsy specimen is obtained and specimen is then analyzed by computer. Results are very accurate. Staff pathologists also review the slides.
No special precaution is taken before oral biopsy procedure and after appointment; the biopsied area might be sore and cause discomfort for which pain meds can be given to the patient. .
