Root amputation, also known as root resection, is a dental surgical procedure in which one or more roots of a multi-rooted tooth are removed while preserving the remaining healthy portion of the tooth. This procedure is typically performed to address specific dental issues affecting one root of a multi-rooted tooth, such as extensive decay, infection, or trauma, while retaining the functionality and stability of the remaining roots and tooth structure.

Here’s an overview of the root amputation procedure:

1. Indications:

• Root amputation is indicated when one root of a multi-rooted tooth is significantly compromised or affected by conditions such as advanced periodontal disease, root fractures, extensive decay, or localized infection.
• The goal of root amputation is to remove the diseased or damaged root while preserving the remaining healthy roots and tooth structure, thus maintaining the functionality and integrity of the tooth.

1. Preoperative Assessment:

• Before the procedure, the dentist will conduct a comprehensive evaluation of the affected tooth, including clinical examination and radiographic assessment, to determine the extent of damage or infection and plan the treatment accordingly.
• Local anesthesia is administered to ensure the patient’s comfort during the procedure.

1. Procedure:

• Tooth isolation: The tooth and surrounding area are isolated using a dental dam or other protective barrier to maintain a clean and sterile field.
• Tooth sectioning: Using precise dental instruments, the dentist carefully divides the tooth along the furcation (the area where the roots meet) to access the affected root.
• Root removal: The diseased or damaged root is surgically removed, along with any associated infection, debris, or damaged tissue. The remaining healthy roots and surrounding bone are preserved.
• Root-end sealing: After root removal, the root canal(s) of the remaining roots may be cleaned, shaped, and filled with a biocompatible material to seal the root ends and prevent recontamination or reinfection.
• Restoration: Once the root amputation procedure is completed, the remaining portion of the tooth may be restored with a filling material or crown to restore function and aesthetics.

1. Postoperative Care:

• Following the procedure, the patient may experience some discomfort or swelling, which can be managed with pain medication and cold compresses applied to the outside of the cheek.
• Patients are advised to follow postoperative instructions provided by the dentist, including dietary restrictions, oral hygiene practices, and any prescribed medications.
• Regular follow-up appointments are scheduled to monitor healing, assess the stability of the remaining tooth structure, and address any concerns or complications.

1. Prognosis:

• The success of root amputation depends on various factors, including the extent of damage or infection, the patient’s oral hygiene, and compliance with postoperative care instructions.
• With proper care and maintenance, a tooth that has undergone root amputation can continue to function effectively for many years, providing chewing function and aesthetics similar to a natural tooth.

In summary, root amputation is a dental procedure performed to remove one or more roots of a multi-rooted tooth while preserving the remaining healthy roots and tooth structure. It is indicated to address specific dental issues affecting one root of a tooth, such as extensive decay, infection, or trauma, while retaining the functionality and stability of the tooth. If you have a tooth that may require root amputation or if you have any questions about the procedure, it’s important to consult with your dentist for a thorough evaluation and personalized treatment plan.
