Hemisection
Hemisection
Hemisection (pronounced: heh-mi-sek-shun) is a surgical procedure in dentistry where the involved tooth, usually a molar, is divided into two halves. This procedure is typically performed when a tooth has severe periodontal disease or when one root is affected while the other is still healthy.
Etymology
The term "hemisection" is derived from the Greek words "hemi," meaning half, and "section," meaning to cut.
Procedure
The hemisection procedure involves the removal of one root and the associated crown portion, leaving a healthy one-rooted molar which can be maintained in the mouth. The procedure is performed under local anesthesia and the remaining tooth structure is usually restored with a crown.
Indications
Hemisection may be indicated in cases of root fractures, severe bone loss due to periodontal disease, root caries, or other conditions affecting only one root of a multi-rooted tooth.
Contraindications
Contraindications for hemisection include inadequate crown-root ratio, poor periodontal status, non-restorable crown, and unfavorable endodontic prognosis.
