The recall interval in patients with furcation involvement is comparatively shorter than the patients with no furcation involvement. How to do research? Six months postsurgical vertical measurements at the control site with the stent. Leave a Reply Click here to cancel reply. The mesial and distal roots may have a definite bifurcation point or they may be fused for all or part of their length.
In mandibular molars, the procedure involves removal of one root with retaining the complete crown of the tooth. Following are the treatment procedure which are considered while making a treatment plan for maxillary and mandibular molars with grade III furcation involvement.
Probing of pockets related to the attachment level. Sanz M, Givannoli JL. Prior to the surgical procedure, thorough scaling and root planing were performed. It has been observed managemebt molars with restorations have a higher prevalence of furcation involvement than the non-restored molars.
Root divergence of mandibular second molar is less than the first molar.
[Furcation involvement and its management].
The test and the control sites were chosen with the toss of a coin. Both the treatment modalities resulted in the reduction of horizontal probing depth values. There is slight bone loss in the furcation area. Managemnt root cones start at the furcation point from where they may take various shapes diverging from the root trunk.
Presently, there is no uniformity in the terms used to describe various treatments for teeth with furcation involvement.
Both short term and long term results of this therapy have reported variable results with this therapy. Bunyaratavej P, Wang HL. All the depressions found on the root surface of the second molar are usually shallower than the first molar.
However, reduction in the mean horizontal probing depth suggested a considerable change from grade II to involveement I in all of the defects studied. The coronal portion of the membrane was tightly secured to the cementoenamel junction CEJ of the tooth, with chromic catgut sutures [ Figure 10 ].
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. This is named as a Cul-de-sac which means a dead end street. Healing and repair of osseous defects.
Table 1 Changes in gingival and plaque scores. In the case of vertical root fracture involving trunk of the root, frequently its extension to furcation area is found. In one study, the prevalence of assessor canals in the furcation region of molars has been found to be The contents were then mixed with the blunt instrument and transferred to the defect with a plastic filling instrument and condensed.
The interproximal furcation is best maintained by an interdental brush whereas facial and lingual furcations are better maintained by end tuft brush, rubber tip stimulator, or toothpick-in-holder. Reliability of attachment measurements using the cementoenamel junction and a plastic stent.
Automatically changes to Flash or non-Flash embed. Bone loss is present on one or more aspects of the furcation, but a portion of the alveolar bone and periodontal ligament remains intact, allowing only a partial penetration of the probe into the furcation. The procedure involves removal of a root without removal of the overhanging portion of the crown Figure However, complete hard and soft tissue formation may take as long as 6 months or more. TFO is a predisposing factor for a more rapid involvement of furcation in inflammatory periodontal diseases.
Further, it has been stated that probing depth reduction was more with all barrier types in GTR procedure as compared to open flap debridement. Factors affecting decision-making knvolvement treatment of molars with furcation involvement include tooth mobility, tooth position, lack of antagonist tooth, the degree of furcation involvement and remaining bone support. Presurgical horizontal measurement at the control site with the stent.
These factors may be classified into three categories, Local factors: The interradicular bone is completely destroyed similar to grade III lesions, in addition, there is gingival tissue recession making furcation opening clinically visible. Etiology of furcation involvement The most common etiology of furcation involvement is bacterial plaque causing inflammation in periodontal tissues.
Furcation involvement and its treatment –
The membrane was soaked in normal saline solution to improve its adhesion properties as recommended by the manufacturer. The root trunk of both first and second molar has a depression between the bifurcation and cervical line.
