Hemisection is usually suggested in Mandibular Molars which have undergone failed Root canal treatment cases where we can see Furcation involvement making it difficult to clean using traditional Root canal therapy. The other reason can be due to procedural Errors by the Dentist is treating infected teeth such as Perforations etc.
The main idea behind Hemisection is to preserve as much of natural tooth structure as possible for future prosthetic process. Success rate of Hemisection is pretty good if all protocols are followed. Other procedures similar to Hemisection: Radisection: It is a procedure done to remove affected roots of Maxillary teeth, it is similar to Hemisection but done on Maxillarry teeth.
Let us look at the Indications and Contra-Indications of Hemisection. Vertical fracture of the tooth one root , in cases where the vertical fracture is restricted to only one root while the other root is not affected, hemisection is preferred to save the tooth. A single tooth one root of multirooted tooth is affected in a multi unit Prosthetic Bridge, it is financially and ethically best to go for Hemisection if possible and remodel the bridge instead of removing and replacing the entire bridge.
Contraindications of Hemisection: Complicated Root anatomy making it difficult to Section one root without damaging the adjacent root. Fusion of Roots, Curved Roots etc. Retained Root having calcified or inoperable canals Adjacent teeth are strong enough for fabricating a bridge Hemisection Procedure: The affected or involved tooth needs to be accessed to make sure whether the root which is going to be retained is without infection and has sufficient bone support.
The tooth which is going to be Hemisected should undergo Root canal Treatment, in case it is a failed root canal treated tooth, Re-RCT should be done. Now proper Radiographic analysis should be done to decide of the location of the sectioning without damaging the root which is set to be retained. With a new Bur section the Tooth crown down till the Furcation is reached and with the help of an elevator using mild rotating force break the tooth into two Now carefully luxate the root to be extracted and remove it.
The retained tooth portion should be filled with Composite restoration Crown portion. After the healing of the extraction site is completed, a bridge or single crown is preferred over the remaining tooth.

E-mail: moc. Abstract Hemisection is sectioning of multi-rooted teeth with its crown portion, with the loss of periodontal attachment and is performed to retain the original tooth structure and attain the fixed prosthodontic prosthesis. We describe hemisection of a mandibular molar tooth followed by adequate restoration in a young patient. Management of periodontally involved molars with extensive decay is a challenging and is limited to dental extraction and replacement with implants. Pain was mild and intermittent in nature, which aggravated on mastication. Clinical examination revealed deep caries with no other detectable abnormality. On intraoral examination, tooth was tender on percussion and deep caries was present in relation to lower right first and second molar teeth with a deep periodontal pocket on the mesial surface of the first molar.

Tooth hemisection What is a hemisection? A hemisection is the procedure of cutting a tooth that has two roots in half. This will create a front half and a back half. This procedure can be done by a periodontist, an experienced dentist, an endodontist, or an oral surgeon. Hemisection means division into two. Since the upper molars have three roots, hemisections can not be performed on the upper molars.
