The procedure involves root canal treatment of the involved tooth and dividing the molar into two parts each having an individual crown Figure The bone loss is minimal, so sometimes is not shown on the radiologic image.
As already mentioned furcations are areas of complex anatomic morphology 29 and are difficult to debride by routine periodontal instrumentation The resorbable GTR membrane with bone material was more effective in the treatment of furcation defects than open debridement alone.
A textbook of periodontics and implantology. Biological aspect Dental implants: Leave a Reply Click here to cancel reply. The endodontic treatment of tooth resolves the periodontal problem also.
The shape of mandibular third molar varies considerably from individual to individual. Presently, there is no uniformity in the terms used to describe various treatments for teeth with furcation involvement.
It must be made sure by clinical and radiographic examination that following root furaction each root cone has an adequate amount of bone support following the procedure. Furcation involvement is probably the most difficult type of defect to standardize.
[Furcation involvement and its management].
Other predisposing and contributing factors which facilitate furcation involvement include tooth brush trauma causing recession and loss of attachment, trauma from occlusion, endodontic lesions that get an access to furcation area, the thickness of investing alveolar process, root fracture and iatrogenic factors. TFO is a predisposing factor for a more rapid involvement of furcation in inflammatory periodontal diseases. The access to the furcation area is difficult both for the dentist and patient, and their treatment constitutes an enormous challenge.
The major disadvantage of the procedure is disease progression in the furcation hidden by the covering and therapeutic failure. The clinical significance of CEP is that while attempting regeneration in involved furcation, CEP should be removed because connective tissue does not attach to enamel and a long junctional epithelium shall be formed which is easily susceptible to breakdown. There is slight bone loss in the furcation area. The root cone with adequate bone support should be saved so that it can withstand occlusal forces.

Tarnow and Fletcher 27 proposed a classification used Grades I, II, III proposed previously by Glickman 22 with an additional sub-classification based on manzgement invasion from the furcation fornix: Grade II or Cul-de-sac like furcation defect can be treated by both regenerative and resective procedures. Periodontal disease in pregnancy. Furcationplasty can be applied to the buccal and lingual furcation areas. This was carried out at the baseline and at six months postoperatively.
References available in the hard copy of the website Periobasics: The furcation defect is clearly visible on radiographs. Another treatment is covering the furcation with rurcation plastic surgery. These materials have been shown to be osteoconductive, that is, they can promote the growth of bone into areas that they would not normally occupy.
Trauma from occlusion TFO: Hemisection is defined as the removal of half of a tooth performed by sectioning the tooth and removing one root. Sanz M, Givannoli JL. The bone graft material and the bioabsorbable collagen membrane used in the study appeared to be biocompatible and safe.
The treatment performed included coronal scaling only, scaling and root planing, scaling and root planing plus modified Widman flap, and open flap scaling and root planing with osseous resection.
Both vertical and horizontal attachment gains were of the magnitude of within 1 mm, and in none of the cases was the furcation closed or any significant difference between the guided tissue regeneration and open flap debridement seen. All the depressions found on the root surface of the second molar are usually shallower than the first molar.
The prognosis of the tooth is established only after the exact condition of furcation is known. Root amputation Hemisection Trisection Tunneling procedure: This is an open-access article distributed under the terms of the Creative Commons Attribution-Noncommercial-Share Alike 3.
This may be explained by the biocompatibility of the collagen membrane and its hemostatic and chemotactic functions.
The mean gain in the relative clinical attachment levels in the test and control groups at the end of six months were 2. The results of the study demonstrated Tooth anatomy Tooth mobility Crown-root ratio Severity of attachment loss Inter-arch and intra-arch occlusal relationship Cost-benefit ratio for retaining a portion of the root Patient-related factors: Furcation-involved molar teeth respond less favorably to conventional periodontal therapy, and molars are lost more often than any other tooth type.
The subjects were recalled after four to six weeks for surgery. The managmeent were seen at the end of the first week when the sutures were removed and were instructed to use 10 ml of 0. These changes reflect reduction of the horizontal inter-radicular probe penetration.
