Oral Biopsy - An Overview

What is an Oral biopsy?

In Oral biopsy is a surgical procedure in which a small tissue sample removes from any abnormality or suspicion section for microscopic examination and further detects the presence or absence of any cancerous cells. Intra-oral biopsies perform to make sure a proper diagnosis.

Oral biopsies used to diagnose situations consisting of oral cancer:

  • Mouth cancer
  • Oropharynx cancer (which includes the tonsils, base of tongue, and soft palate)


Why need of oral biopsy?


Dentists recommended oral biopsy in such cases:


  • Dentists often recommend a biopsy when they are unsure of the cause of the disease or do not know how far it has spread or precisely what it is like.
  • Some lesions can intrude along with your oral function, persisting for more than two weeks even after removing local irritants. You may want a biopsy to determine what's causing the lesion so that a correct prognosis can be supplied and a proper remedy can be done.
  • Some bone lesions could not be identified generally by clinical examination or X-rays. To examine that lesion, an oral biopsy is recommended.
  • To check what causes oral symptoms such as mouth sores, white or black patches on the tongue or gums, change of taste, or trouble swallowing.
  • Sometimes, after examination, the dentist suspects a patient has oral cancer, and a biopsy can be performed to confirm the examination.


Types of biopsy


Aspiration biopsy: In this biopsy, a tiny sample of cells from a lesion is taken by a needle or syringe. If the surgeon cannot drain any fluid or air, it means the lesion is solid.


Punch biopsy: This biopsy is done with a punch tool for incisional and excisional purposes. This type of Oral Biopsy is best suited for diagnosing oral manifestations of mucocutaneous and painful situations of the oral cavitywhich includes lichen planus.


Bone biopsy: This biopsy is used to diagnose abnormal conditions affecting your jaw bone. The dental surgeon will take a small sample of bone after making a small cut in your gum and then stitch the cut together.


Brush Biopsy: In this kind of Oral Biopsy, firm pressure with a round brush is implemented and rotated give to ten times, causing light abrasion. The brush's cellular material is transferred to a glass slide, preserved, and dried.


Is oral biopsy painful?

The oral biopsy is painless. A patient only feels a sharp pinch or pinprick because of the needle; the surgeon used to take a biopsy or inject local anesthetics. After the biopsy patient may experience mild pain for 4 - 6 hours or when the local anesthetic stop. Oral painkillers can treat this pain. 

Some patients may experience swallowing after the biopsy procedure within 2 or 3 days, which can be lessened by using ice on the biopsy site for 2-3 days. It is normal to have some



oozing, blood-tinted Sliva overnight or for the next day. If you feel it necessary, take simple painkillers to help with your pain.


Will there be bleeding after the biopsy?

There'll be a little bleeding at the time of biopsy that usually stops very quickly, and there will be no further problem if your wound is stitched correctly. Sometimes biopsy site starts to


bleed again when patients reach home, which can be stopped through making pressure over the place for 10 minutes with a handkerchief or swab. If bleeding doesn't stop, contact your surgeon as soon as possible.


How long does it take to heal?

Oral biopsy typically takes 2-3 days to 2 weeks to heal, depending on the location and type of biopsy done.

If a biopsy is done generally with local anesthetics without any stitches, the pain will last only for the initial 2 -3 days. The patient will feel improvement after it.

The biopsy commonly leaves a tiny hollw that often needs stitching. If a biopsy is done under local anesthetics with stitches, it takes two weeks to heal completely.


Instructions to follow after biopsy:


  • On the day of the biopsy, the patient should avoid rinsing their mouth out vigorously; this may cause bleeding.
  • Avoid biting the area of biopsy and brush gently.
  • Start taking pain relievers before the anesthesia wears off.
  • The patient will not be able to drink or generally eat after biopsy, avoid eating hot, spicy, or sharp food and don't drink anything hot (coffee, tea), and allow all meals or drinks to cool down to room temperature.
  • Avoid any exhausted exercise for the rest of the day, either at work or during your leisure time.
  • The affected person should avoid smoking for at least 72 hours, as it increase the risk of wound smoking.

  • Increased redness or soreness at the biopsy site even after a painkiller.
  • If the wound bleeds persistently.
  • Severe pain.
