Dental Code D3920: Hemisection (including any root removal), not including root canal therapy

Dental Code D3920 refers to a dental procedure known as hemisection, which involves the removal of a specific portion of a multi-rooted tooth, typically due to severe damage or infection. It is important to note that this procedure does not include root canal therapy. 

Dental Code D3920, hemisection, is a dental procedure performed when a multi-rooted tooth is extensively damaged or infected. This code specifically refers to the removal of one root and the associated portion of the tooth, excluding the need for root canal therapy. Hemisection is typically performed when the affected tooth cannot be saved entirely, but a portion of it is still healthy and can be preserved.

The first step in the hemisection procedure involves a comprehensive examination and diagnosis by a dental professional. The dentist will evaluate the affected tooth's condition, considering factors such as decay, infection, gum disease, bone loss, and the overall feasibility of preserving a portion of the tooth. X-rays and other imaging techniques may be used to assess the extent of damage and plan the treatment accordingly.

Before starting the procedure, the dentist will administer local anesthesia to ensure that the patient remains comfortable and pain-free throughout the process. Local anesthesia numbs the area around the tooth and prevents any discomfort during the hemisection. The dentist may use a topical anesthetic gel to numb the gums before injecting the local anesthetic. The gel is applied with a cotton swab or a special syringe, and it helps reduce the sensation of the needle prick.

Once the anesthesia takes effect, the dentist will isolate the tooth using a dental dam or other suitable methods. A dental dam is a thin, flexible sheet made of latex or non-latex material that is placed over the tooth to keep it isolated from saliva and other oral fluids. This isolation helps in maintaining a clean and dry operating field. The dentist will then carefully access the tooth by creating an incision in the gum tissue near the affected area, allowing clear visibility and access to the roots. The gum tissue is gently pulled back, and a small flap is created to expose the root surfaces.

In this crucial step, the dentist will remove the diseased or damaged root and the associated portion of the tooth. Advanced dental instruments, such as dental drills and ultrasonic devices, may be used to carefully section the tooth, separating the healthy portion from the affected roots. The dentist will ensure that no infected or damaged tissues remain, promoting optimal healing and preventing further complications. The use of ultrasonic instruments helps in precise and controlled removal of the root and reduces the risk of damaging the surrounding healthy tissues.

After removing the affected root and tooth portion, the dentist will thoroughly clean and disinfect the remaining healthy portion of the tooth. This step is crucial to eliminate any residual bacteria or debris, reducing the risk of infection and promoting successful healing. The dentist may use a combination of specialized dental instruments, such as root canal files and irrigating solutions, to clean the root canals and ensure proper disinfection. This thorough cleaning helps remove any remaining infected or necrotic tissue and prepares the tooth for the final restoration.

Once the tooth is cleaned and disinfected, the dentist will proceed with the restoration process. Depending on the extent of the hemisection, a suitable restoration option will be chosen, such as a dental filling, crown, or a dental bridge. The restoration aims to reinforce the remaining healthy portion of the tooth, ensuring its stability, function, and aesthetic appearance. If a significant portion of the tooth is missing after the hemisection, a dental crown or bridge may be recommended to restore its shape, strength, and chewing ability. The dentist will take impressions of the tooth and surrounding teeth to create custom-made restorations that fit precisely and blend seamlessly with the natural teeth.

Dental Code D3920, hemisection, is a dental procedure performed to remove a damaged or infected root and the associated portion of a multi-rooted tooth. This procedure aims to preserve the healthy portion of the tooth while eliminating the diseased or damaged portion. The steps involved in hemisection include diagnosis and treatment planning, local anesthesia, isolation and access, root removal, cleaning and disinfection, and restoration. By following these steps, dentists can effectively manage severe dental conditions while promoting oral health and preserving the patient's natural dentition.
