Definition and Types of Tooth Hemisection
- Tooth hemisection is a form of endodontic surgery.
- It involves separating a root and its overlying crown from the rest of the tooth.
- Root resection and apicoectomy are alternative procedures.
- Root resection involves removing a root while leaving the crown intact.
- Apicoectomy involves removing only the tip of the root.

Applicability and Performers of Hemisection
- Hemisection is performed on molars, which have 2 to 3 roots.
- Incisors, canines, and lower premolars have only 1 root each.
- Hemisections are usually performed on lower molars rather than upper molars.
- General dentists or periodontists perform the procedure.
- The affected side of the molar's root and crown are removed.

Procedure of Tooth Hemisection
- The dentist makes a small incision in the gum tissue to expose the tooth's deeper structure.
- The roots are separated during the procedure.
- Decay and other parts of the tooth are removed to protect overall oral health.
- The area is cleaned with sterile saline solutions.
- If necessary, the small cuts are stitched closed.

Temporary and Permanent Restoration
- After the hemisection, a temporary crown or filling is placed on the tooth.
- The temporary restoration will be replaced with a permanent fixture later.
- The temporary restoration protects the tooth during the healing process.
- The permanent restoration ensures long-term functionality and aesthetics.
- The type of permanent restoration may vary based on individual needs.

Duration and Preparatory Procedures
- A hemisection typically takes between 30 minutes and an hour to complete.
- The duration depends on the extent of decay and periodontal disease.
- In many cases, an initial procedure is required before the hemisection.
- The initial procedure prepares the tooth for the hemisection.
- It may involve addressing specific dental issues or ensuring optimal oral health.
