Hemisection: A Window of Hope For Freezing Tooth

Abstract

Advances in dentistry, as well as the increased desire of patients to maintain their dentition, have led to treatment of teeth that once would have been removed. Mandibular first molars are the most commonly extracted teeth due to dental caries and periodontal disease. These teeth are the major standpoint for occlusion, and also have a wide pericemental area. Hence, any defect in the root either mesial or distal, extraction is the most common treatment planned. Under specific conditions, only the diseased part of the tooth can be extracted after an endodontic treatment. A modified fixed partial denture design is fabricated to splint the remaining portion of the tooth to adjacent teeth. This procedure though daunting can be easily achieved and maintained successfully.

Hemisection: A conservative management of periodontally involved molar tooth in a young patient

“…Buhler (1988) observed 32% failure rate in hemisection cases attributed to endodontic pathology and root fracture while other authors (0-9%) have shown a greater success in hemisection cases in the long-term studies. [ 5 9 10 ] In the present case, good prognosis was observed with proper occlusion, absence of mobility and healthy periodontal condition up to 6 months of follow-up. Concurring with previous reports, hemisection is a valid treatment option for the molar teeth's in young children, which otherwise have to be extracted due to extensive caries.…”

“…Management of periodontally involved molars with extensive decay is a challenging and is limited to dental extraction and replacement with implants. [ 5 ] Nevertheless, treatment strategy to retain such teeth involves periodontal, prosthodontic and endodontic assessment for appropriate selection to allow for stronger survival. [ 1 ] Hemisection is a conservative way of preserving tooth.…”

Preservation vs Extraction of Carious Multirooted Teeth

“…Management of periodontally involved molars with extensive caries and unrestorable condition is a challenging enterprise and is limited to dental extraction. 8 If caries of multirooted teeth of lower jaw is limited to one root, and the other root is unharmed and robust, hemisection may be a suitable alternative to extraction. Hemisection is also indicated in cases, such as severe vertical bone loss around one root of a multirooted tooth, furcation destruction, nonrestorable portion of a multirooted tooth, bur perforations during endodontic access preparation or during search for canal orifices, and misdirected files during canal negotiation.…”

Coronal-Radicular Amputation or Hemisection? A Report Case in Lower Molar

“…The lower molars are the more frequently extracted because a high incidence of decay and periodontal disease that involved furca or roots that impossibility endodontic and prosthetic treatments. In this topic the radicular hemisection or coronal-radicular amputation plays an important role for conservate these teeth [7]. Saad et al (2009) reported a hemisection in molar with affectation distal, it was pillar in prosthetic restoration of units three, it was affected with extends cavity in middle third.…”
