The mean gingival involvenent plaque scores were significantly reduced at the end of three months and six months in both the test and the control groups. Upload from Desktop Single File Upload. Furthermore, the chemotactic function of the collagen membrane promotes fibroblast migration that ensures primary wound coverage.
The shapes of roots may have different shapes and may be completely or incompletely fused. The treatment of teeth with furcation involvement ranges from thorough manaement to regenerative procedures and, if the lesion progresses, to extraction.
Furcation involvement and its treatment –
This was less favorable than the manxgement from the systematic review reported by Murphy and Gunsolley,[ 17 ] which showed that GTR had more reduction in vertical probing depth compared to the Open Flap Debridement OFD controls. It can be determined by clinical and radiographic examination. The most common etiology of furcation involvement is bacterial plaque causing inflammation in periodontal tissues.
These results were in agreement with Lekovic et al [ 16 ] and Anderegg et al. You must be logged in to post a comment. A total of eight patients, four females and four males, in the age group of 18 to 65 years, with bilateral buccal grade II furcation defects in the mandibular molars, participated in the study.
It is one of the co-factors contributing to the development of furcation lesion. It was subsequently adapted over the defect extending 2 – 3 mm apical to the crest of the existing bone, so as to provide a broad base during the placement.
[Furcation involvement and its management].
The results of the study demonstrated that crestal bone levels and attachment levels in the furcations were maintained for this time period. Go to Application Have a question? Furcation involvement worsens the prognosis of the tooth because long-term studies indicate that teeth with furcation involvement are the teeth that tend to be lost over time. Masters and Hoskins 7 reported the incidence of CEPs anx extracted human teeth and suggested their possible implication in isolated furcation involvement.
Vertical destruction reaching two-thirds of the inter-radicular height mm. The furcaion of root divergence also varies from tooth to tooth.
Before we discuss the treatment of furcation defects, let us discuss these terminologies first. Scaling and root planing. Medical grade calcium sulfate hemihydrates versus expanded polytetrafluoroethylene in the treatment of mandibular Class II furcations. Contraindications for the procedure involve poor oral hygiene, fused roots, unfavorable tissue architecture and roots which are endodontically untreatable.
Following is the detailed description of these factors. Extent of attachment loss on furcation depends on presence of these factors: Root resection generally indicates the removal of a root without any information on the crown of the tooth The coronal portion of the membrane was tightly secured to the cementoenamel junction CEJ of the tooth, with chromic catgut sutures [ Figure 10 ].
Occlusal adjustments are done to facilitate balanced distribution of occlusal forces. The mean reduction in the vertical probing depth values in the test and control groups were 1.
The term hemisection has been used interchangeably with root resection In this anr, selection of mandibular grade II defects was done based on the observation by Sanz and Givannoli,[ 11 ] who stated that, “placement of a barrier membrane should not be indicated in the treatment of maxillary molars with furcation involvement. All the eight subjects completed the study. The probe penetrates more than 3 mm without transpierce to the opposed side of the furcation.
Five years follow-up results demonstrated that 4 invoovement of 7 teeth had evidence of carious lesions. In mandibular molars, the procedure involves removal of one root with retaining the complete crown of the tooth. Let us now discuss the anatomy of various bifurcated and trifurcated teeth in detail. Following are some of these proposed classifications for furcation involvement, Classifications on the basis of horizontal component of bone loss in furcation: Footnotes Source of Support: 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.
Some authors have manzgement coronally advanced flap with or without root conditioning and placement of bone graft Mandibular neurovascular considerations Dental implants: In the case of vertical root fracture involving trunk of the root, frequently its extension to furcation area is found.
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. It must be made sure by clinical and radiographic examination that following root separation each root cone has an adequate amount of bone support following the procedure.
