Biopsy - Dr. Dadoo's Family Dental Clinic

A biopsy in dentistry is a diagnostic procedure in which a small sample of tissue is removed from the mouth or jaw and examined under a microscope. It is performed to identify the nature of abnormal growths, lesions, or persistent changes in oral tissues.

Why is a Dental Biopsy Needed?

A biopsy is advised when there are signs of abnormal changes in the oral tissues that need further evaluation:

  • Persistent ulcers or sores: Lesions that do not heal over time may indicate underlying issues and require investigation
  • Unusual lumps or swelling: Any unexplained growth in the mouth or jaw should be examined to determine its nature
  • White or red patches: Conditions like leukoplakia or erythroplakia can sometimes be precancerous and need careful assessment
  • Suspicious growths: Tissue changes that may suggest infection, cysts, or tumors require confirmation through biopsy
  • To rule out or confirm oral cancer: A biopsy is the most reliable way to diagnose or exclude cancerous conditions

Early detection through biopsy helps ensure accurate diagnosis and timely treatment, improving overall outcomes and oral health.

Types of Dental Biopsy

1. Incisional Biopsy

In an incisional biopsy, only a small portion of the suspicious tissue is removed for examination. This method is typically used when the lesion is large or located in an area where complete removal is not initially possible. It helps in diagnosing the condition before planning further treatment.

2. Excisional Biopsy

An excisional biopsy involves the complete removal of the lesion or abnormal growth. It is commonly performed for small, well-defined, and easily accessible lesions. In many cases, this procedure can be both diagnostic and therapeutic, as the entire problem area is removed.

3. Fine Needle Aspiration (FNA)

Fine Needle Aspiration uses a thin, hollow needle to withdraw cells or fluid from a swelling or lump. It is a minimally invasive technique often used for cystic lesions or soft tissue swellings, helping to quickly determine the nature of the condition with minimal discomfort.

Procedure Overview

Performed Under Local Anesthesia

The biopsy procedure is usually carried out under local anesthesia, ensuring the area is completely numb and the patient remains comfortable and pain-free throughout.

Tissue Sample Removal

The dentist or oral surgeon carefully removes a small sample of the affected tissue using precise instruments, depending on the type and location of the lesion.

Suturing (If Required)

If the biopsy site is large or needs support for proper healing, stitches (sutures) may be placed. These help control bleeding and promote faster recovery.

Laboratory Examination

The collected tissue sample is then sent to a specialized laboratory for histopathological examination. Under a microscope, experts analyze the cells to determine the exact nature of the condition and provide an accurate diagnosis.
