Root resection procedures are indicated in the treatment of periodontal furcation involvement and root fractures in one of the roots of multirooted teeth. Their long-term prognosis is comparable to that of implants. The present article is a case report of root separation and removal of the mesial root along with crown in mandibular first molar which was successfully employed as a part of the oral rehabilitation procedure. [ABSTRACT FROM AUTHOR]

Hemisection of a molar denotes the removal or separation of a root along with its accompanying part of crown. It is a suitable treatment option when caries or periodontal damage is restricted to one root while the other root is relatively healthy. Hemisection of the affected tooth helps to retain the tooth structure, surrounding alveolar bone, and may also facilitate the placement of a fixed prosthesis. This report describes the hemisection as a successful treatment option to save grossly carious mandibular first molars with or without periodontal involvement. With careful treatment planning and precise surgical management hemisection and prosthetic rehabilitation can yield promising results. Undesirable consequences of tooth loss were prevented in this way. [ABSTRACT FROM AUTHOR]

Hemisection denotes removal or separation of root with its accompanying crown portion of mandibular molars. It is one of the treatment options for preserving the remaining part of the molar having sound periodontium. Careful case selection is necessary for long-term success. The present case report demonstrates the successful management of hemisection of 36 with a fixed partial denture. [ABSTRACT FROM AUTHOR]

Hemisection is a procedure involving the removal of an untreatable root with an accompanied crown portion while saving the other healthy root with adequate bone support. This case report represents the treatment of 2nd mandibular molar with irretrievable and unable to bypass separated instruments in the mesiobuccal canal of the mesial root. After sectioning the tooth, mesial root with the crown portion was extracted, and the remaining part of the tooth was restored as a premolar. Restorative rehabilitation was done by cementing a three-unit metal ceramic bridge. The good outcomes of endodontic treatment and patient demand towards the conservation of tooth encouraged the procedure of hemisection. For the preservation of terminal mandibular molars with irretrievable and unable to bypass separated instruments, hemisection can be considered as an alternative treatment option our objective is to conserve terminal mandibular molar with adequate bone support as a replacement in this area is complex, time consuming, and costly.

The disciplines of endodontics and periodontics fuse when molars that have bifurcation or trifurcation involvements are treated with hemisection and radosection. Attempts to save parts of teeth go back 100 years or more, but it is the increased predictability of success of endodontic therapy and the increased sophistication of periodontal treatment that have given us the means to save molars with furcation problems that, otherwise, would be lost. When restorative dentistry has already been finished, and the retention of part of the tooth will extend the life of a crown or fixed partial denture, the patient certainly deserves the option of hemisection or root amputation rather than extraction. The aim of the study is to evaluate the knowledge, attitude and practice of hemisection and radisection among dentists. This survey is conducted among dental students and dental practitioners. A self administered questionnaire was made and circulated among the participants. The sample size was 132 and the questionnaire was circulated through online means. The data was obtained and the results were tabulated using excel and statistical analysis was done using SPSS software. From the survey, all dental practitioners (58) and interns (72) knew that there are procedures to save the tooth when furcation is involved; however interns (2) didn't know about such procedures, however Pearson's Chi square test was not significant (p>0.05). Dental practitioners (56) and interns (67) knew that mandibular molars commonly undergo hemisection, however the Pearson's Chi square test was not significant (p>0.05). From this study it can be concluded that both dental practitioners and interns had sufficient knowledge about hemisection and radisection. However only dental practitioners who are having experience and confidence have responded that they will be able to perform hemisection and radisection in their regular practice. It is always better to save and preserve natural tooth as much as possible and it is important to train the upcoming dental graduates in performing hemisection and radisection.

Mandibular molar tooth function is important for cats, however, current veterinary dental practice is to extract teeth affected by even very small resorptive lesions. The aim of this article was to describe an attempt at salvaging mandibular molar teeth where the mesial root and associated crown remained unaffected by resorption. Three cats presented with localised resorption of the distal root of a mandibular molar tooth were treated by hemisection, extraction of the distal root and endodontic treatment of the mesial root. The oral function was maintained in all three cats with no clinical evidence of pain or further resorption at follow-up 10 months post treatment. One cat was also examined at 27 months post treatment, at which stage there was still no oral discomfort and the tooth appeared fine but there were radiographic signs suggestive of early apical resorption. Whilst longer term follow-up is required, it appears that hemisection may be an acceptable treatment for these localised resorptive lesions, at least for the short to medium term.

Hemisection is the separation of the whole tooth from the mesial to distal in the upper molars and premolars and from the buccal to lingual in the lower molars, and removal of the pathological root together with the crown. Hemisection is an appropriate treatment option when caries, resorption, iatrogenic complication or periodontal damage is limited to one root and the other root is relatively healthy. Hemisection of the affected tooth helps to preserve alveolar bone which surrounding the tooth structure and supports fixed dentures. Therefore, when a molar tooth should be extracted only because of damage at one root, hemisection or root amputation treatment alternatives should be kept in mind. This case series describes hemisection as a successful treatment method to recover teeth with iatrogenic complications and irretrievable root caries were limited to single root.

Gemination aka twinning and fusion, are rare occurrences in posterior mandibular teeth, often requiring endodontic and surgical treatment for functional, orthodontic or cosmetic reasons. The diagnosis and design of a precise treatment plan in cases involving double teeth are in most cases challenging. The purpose of this case report is to describe a successful multidisciplinary treatment protocol for a double tooth. Upon completion of the endodontic, restorative and orthodontic treatments, the clinical and radiographic three-year follow-up revealed that the rest of the transected premolar showed evidence of healing of the supporting tissues and satisfactory cosmetic result.

Tooth hemisection preserves partial tooth structure and reduces the resorption of alveolar bone. The aim of this study was to analyze the feasibility of preserving a molar after hemisection and inserting a dental implant with different prosthetic superstructures by means of finite element analysis. First, the distance between the root of the mandibular second premolar and the distal root of the first molar were measured in 80 cone beam computed tomography (CBCT) data sets. Based on these data, the lower right posterior jaw segment was reconstructed and the geometries of the appropriate implant were imported. Four models were created: (1) Hemi-1: An implant (3.7 × 9 mm) replaced the mesial root of the molar, and a single crown was placed on the implant and residual tooth. (2) Hemi-2: Two separate crowns were generated for the implant and the residual tooth. (3) Single: An implant (5.5 × 9 mm) with crown replaced the whole molar. (4) FPD: A 3-unit fixed partial denture combined the distal residual part of the molar and premolar. The results indicated that stresses in the cortical bone and strains in the majority region of the spongious bone were below the physiological upper limits. There were higher stresses in implant with the Hemi-1 and Single models, which had the same maximum values of 45.0 MPa. The FPD models represented the higher values of stresses in the teeth and strains in PDL compared to other models. From a biomechanical point of view, it can be concluded that a combination of an implant and residual molar after tooth hemisection is an acceptable treatment option. [ABSTRACT FROM AUTHOR]

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 peri-cemental 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. Hemisection may be a valuable form of treatment for molar teeth when caries has progressed to the furcation, or where there is an extensive carious lesion extending subgingivally in one area of the root, making it impossible to place an adequate restoration in that area and the root is considered unrestorable. Hemisection and prosthetic rehabilitation yielded a satisfactory result. [ABSTRACT FROM AUTHOR]

Introduction: Hemisection involves sectioning of a periodontally involved mandibular molar so as to remove the involved root and save the remaining tooth. This procedure helps in saving a tooth which otherwise would have been deemed for extraction. Hemisection refers to removal or separation of root with its accompanying crown portion of two-rooted teeth, most commonly mandibular molars. Method: In this case report, an advanced Endo-Perio lesion on a left mandibular first molar was successfully treated by root-canal treatment and hemisection. This procedure helps preserve the tooth structure, alveolar bone and promote cost savings over other treatment options. Conclusion: Hemisection is a treatment option for saving a mandibular molar which is in advanced stage of periodontal disease of one root. Removal of the affected root will help in retaining the remaining tooth structure. [ABSTRACT FROM AUTHOR]

Diagnosis and management of vertical root fracture is a challenging task for the clinician. The most predictable treatment option for vertical root fractures would be extraction in case of anterior teeth, and hemisection or root amputation of the involved root in the multi-rooted teeth. This case report describes the treatment of a vertically fractured mandibular molar by hemisection followed by the placement of a three unit bridge combining the hemisected root and adjacent second premolar which is successfully in service for more than a year.

The progressing inflammatory periodontal disease, if untreated, ultimately results in attachment loss. This can affect the bifurcation or trifuracation of multirooted teeth. Hemisection is the splitting of a two-rooted tooth into two separate portions. The treatment, management and long-term retention of mandibular molar teeth exhibiting furcation involvement always have been a challenge, especially when the furcation involvement has progressed to a class III furcation. Hemisection refers to removal or separation of root with its accompanying crown portion of two-rooted teeth most likely mandibular molars. Hemi-section of the affected tooth helps preserve the tooth structure, alveolar bone and promote cost savings over other treatment options. This article describes a simple procedure for hemisection in mandibular molar by vertical cut method and its subsequent restoration. [ABSTRACT FROM AUTHOR]

Root resection therapy has been used in the treatment of advanced periodontal disease for nearly 100 years. The preservation of posterior abutment teeth permits oral rehabilitation with fixed bridges instead of removable prosthesis. A case of iatrogenic removable partial denture in relation to 47, causing bone loss till the apex of distal root of 46 came to the department of Periodontics, Sri Siddhsrtha dental college, Tumkur. The decision was taken to hemisect the distal root, as mesial bone and furcation bone was relatively unaffected. Procedure: After phase I therapy, periodontal flap was reflected, area debrided and distal root was resected. The case was followed up for 8 months for the survival of the resected molar. A fixed bridge was given to the patient using 45 and the resected molar with 48 as abutments to replace 47. It has been a year since and hemisected 46 is stable. The keys to long term success appear to be thorough diagnosis, selection of patients with good oral hygiene and careful surgical and restorative management. [ABSTRACT FROM AUTHOR]

Recently, successful implant placement in fresh extraction sockets has been reported. In this case report, we present the results of an immediate implant placement in a fresh extraction socket of a mandibular molar with simultaneous bone regeneration using a nonresorbable membrane and no other graft materials. Clinical and radiographic findings acquired 8 years after implant placement demonstrated a stable peri-implant situation and confirmed a satisfactory treatment result. [ABSTRACT FROM AUTHOR]

An increased wish by patients to maintain their dentition and recent advances in dentistry have led to the treatment and preservation of teeth that once would have been removed. Consequently, hemisections, root amputations, and bisections are procedures frequently used. The prognosis of endodontically treated teeth depends on the type of reconstruction as well as the success of the endodontic treatment. Along with technological improvementsin adhesive resins, cements, and composite restoratives, the evolution of fiber-reinforced posts enables the rehabilitation of endodontically treated teeth with greater esthetics and virtually no predisposition to root fracture. The purpose of this report was to describe the endodontic, surgical, and restorative treatments of a mandibular first molar with anendo-dontically and periodontally diseased mesial root, for functional, orthodontic, and aesthetic reasons. This case report shows that the clinical application of fiber-reinforced composite resins in hemisectioned teeth may be a treatment choice for highly damaged teeth with endodontic and/or periodontal lesions. It also emphasizes the advantages of the elimination of orthodontic and prosthetic treatment needs by different treatment strategies, especially in adolescent patients. [ABSTRACT FROM AUTHOR]

Root amputation and hemisection should be consideredas another weapon in the arsenal of the dental surgeon,determined to retain and not remove the natural teeth.With recent refinements in endodontics, prosthodonticsand restorative dentistry, hemisection is a baton for the extracting teethand has received acceptance as a conservative and dependable dentaltreatment. Careful case selection determines the long term success of the procedure. This case report presents a multidisciplinary approach to salvaging mandibular molar with grossly decayed roots and grade III furcation defect with help of hemisection followed by prosthodonticrehabilitation to maintain a functional rehabilitation.

Advances in dentistry, as well as the increased desire of patients to maintain their dentition, have lead to treatment of teeth that once would have been removed. In order to carry out this present day mandate, periodontally diseased teeth with severe bone loss may well be retained by removal of one or more of their roots. Hemisection of a mandibular molar may be a suitable treatment option when the decay is restricted to one root and the other root is healthy. Hemisection denotes removal or separation of root with its accompanying crown portion of mandibular molars. This procedure represents a form of conservative dentistry, aiming to retain as much of the original tooth structures possible. The success rates in such procedures are very high if selections of cases are done judiciously. This article describes a simple procedure for hemisection in mandibular molar and its subsequent restoration. [ABSTRACT FROM AUTHOR]

Hemisection denotes removal or separation of root with its accompanying crown portion of mandibular molars. This procedure represents a form of conservative dentistry, aiming to retain as much of the original tooth structure as possible. The results are predictable and success rates are high. In this paper a case is presented in which hemisection was done because the tooth was grossly carious along with furcation involvement. Mesial half of tooth was extracted and the remaining tooth was restored as premolar which helped to reduce the masticatory load. [ABSTRACT FROM AUTHOR]
