Masters and Hoskins 7 reported the incidence of CEPs in extracted human teeth and suggested their possible implication in isolated furcation involvement.
The pocket is suprabonyinvolving the soft tissue. The studies included in this systematic review were analyzed for furcation closure rate, horizontal attachment level gain HALvertical attachment level gain VALhorizontal bone fill HBFand vertical bone fill VBF.
The qnd of root divergence also varies from tooth to tooth. The mean gingival and plaque scores were significantly reduced at the end managememt three months and six months in both the test and the control groups.
FURCATION INVOLVEMENT AND ITS MANAGEMENT |authorSTREAM
Presurgical vertical measurements at the test site with the stent. Two occlusal stents, one of clear resin and the other of pink auto polymerizing resin were fabricated by the sprinkle-on method for both the test and control sites. It has been observed that molars with restorations have a higher prevalence of furcation involvement than the non-restored molars.
Connective tissue grafts and coronally positioned flaps can be employed to cover the furcation. There are various factors which are considered while making a diagnosis of furcation involvement furcatkon establishing the prognosis of the involved tooth.
[Furcation involvement and its management].
The resorbable GTR membrane with bone material was more effective in the treatment of furcation defects than open debridement alone. Root divergence of mandibular second molar is less than the first molar. Radiographic change is not usual since bone loss is minimal. The alveolar bone thickness on the buccal aspect of the first molar is less as compared to the second molar and thus chances of fenestration and dehiscence are more on the buccal aspect of the first mandibular molar.
The mean gain in the relative clinical attachment level in the test group was statistically significant at the end of three months and also at the end of six months.
Overhanging restorations result in harboring of plaque resulting in inflammation and thus initiating the development of a furcation lesion. The area under the crown from where the root has been removed should be made self-cleansable by the patient and should allow adequate plaque removal.
The resorbable collagen membrane had excellent handling characteristics and biological acceptance.
Following are some of these proposed classifications for furcation involvement. In addition to this, the surviving root should be aligned so as to provide a proper draw for the resulting fixed prosthetic restoration. The classification proposed by Easley and Drennan 26 was based upon the involvement of the horizontal component aand furcation.
There is a high percentage of molars with patent accessory canals that open in their furcation area In such a situation soft tissue flap can be raised to get access to the root surface.
The presentation is successfully added In Your Favorites. Slight attachment loss has fucation observed in cases where resective osseous surgery for tunnel preparation is done.
The involvwment of resorbable membrane materials brings clear advantages in the clinical management of guided tissue regeneration procedures: Tooth anatomy is the primary determinant in establishing treatment planning for grade III furcation involvement. Before we discuss the treatment of furcation defects, let us discuss these terminologies first.
Periodontitis as a risk factor for cardiovascular diseases Diabetes and periodontal disease: There is slight bone loss in the furcation area.
It is important to determine the extent of furcation involvement to a make an appropriate diagnosis and developing a treatment plan. In general, the overall size of maxillary second molar is smaller than the first molar and larger than the third molar. Following is the detailed description of these factors, Extension of inflammatory periodontal diseases into furcation: Another recent systematic review by Avila-Ortiz et al.
One site in each patient was randomly allocated to the test group and was treated by GTR and Hydroxyapatite bone grafting. 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. Tarnow and Fletcher 27 proposed a classification used Grades I, II, III proposed previously by Glickman 22 with an additional sub-classification based on vertical invasion from the furcation fornix: A retrospective study 60 investigated factors affecting treatment decisions and outcome of root resected molars using a nationwide population-based dataset in Taiwan.
Various terms have been used to describe treatment procedures for furcation involvement in the literature viz; furcationplasty, root amputation, hemisection, root resection, root separation and tunnel preparation.
The results of the study demonstrated It has also been shown that the guided tissue regeneration procedure, using membranes, holds promise for increasing the success of bone grafting. The bone graft material and the bioabsorbable collagen membrane used in the study appeared to be biocompatible and safe. Grade III — The enamel projection extends horizontally into the furcation. Vertical destruction reaching two-thirds of the inter-radicular height mm.
Loe H, Silness J. The maxillary first molar is the largest tooth in the maxillary dental arch. In a study Hirschfeld and Wasserman 1reported that percentage of tooth furccation in furcation-involved molars was However, Lekovic et al [ 16 ] demonstrated that the use of the bone graft did not enhance the effect of the membrane furcqtion respect to the frcation of clinical attachment in furcation defects.
