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.
