The purpose of this study was to compare the clinical, radiographic, and histo[ogic changes that occur in response to three of the most commonly used materials to repair furcation perforations. The results of the experiment showed that amalgam was superior to Cavit and calcium hydroxide as a sealing material of furcation perforations. The most severe reactions occurred in the control group wher...

This human clinical trial evaluated the clinical and histologic response to recombinant human platelet-derived growth factor-BB (rhPDGF-BB) delivered in bone allograft for the treatment of advanced Class II furcation defects. Three mandibular and one maxillary molar furcation defects were treated: Two received 0.5 mg/mL and two received 1.0 mg/mL rhPDGF-BB, in all cases mixed with DFDBA. Clinic...

Furcation lesions are associated with increased risk of progressive loss of connective tissue attachment, alveolar bone resorption, and tooth mortality (Bjorn and Hjort, 1982; Becker et al, 1984; Wang et al, 1994; Wood et al, 1989; Hirshfield and Wasserman, 1978; McFall, 1982; Carranza and Jolkovsky, 1991), representing one of the greatest challenges in periodontal therapy. Surgical management ...

Purpose: A randomized, single-blind, prospective clinical trial was performed to evaluate the effects of plaque control by inter-radicular brushing on class II furcation of lower molars. Methods: Twenty-two patients presenting with at least one class II furcation with horizontal probing depth (PD) ≥ 4 mm on the buccal aspect of lower molars were recruited. Each patient was randomly assigned to ...

INTRODUCTION The present case series evaluates the efficacy of a hydroxyapatite graft material in the management of grade II furcation involvement in first molars. MATERIAL AND METHODS Eight patients presenting with a total of 9 grade II furcation defects in relation to the facial aspect of either maxillary or mandibular first molars were treated with a porous hydroxyapatite alloplast. The cl...

The aim of this in vitro study was to measure critical morphology of molar pulp chambers. One hundred random human maxillary and mandibular molars (200 teeth in total) were used. Each molar was radiographed mesiodistally on a millimeter grid. Using a stereomicroscope, the measurements were read to the nearest 0.5 mm. Results were as follows (mean, mm): pulp chamber floor to furcation, maxillary...

BACKGROUND The objective of this multicenter, randomized trial was to compare enamel matrix derivative (EMD; test) with barrier membranes (control) for the treatment of mandibular buccal Class II furcation defects. METHODS Forty-five patients with 90 comparable defects on contralateral molars were included. Defects were randomly assigned to EMD or bioabsorbable barrier membrane; the contralat...

Purpose: The treatment for furcation involvement is a great challenge to the general dentists. Tunneling may be a treatment alternative for class II and III furcation involvements in mandibular molars with large angle separation and great divergence between the mesial and distal roots. This alternative is a conservative treatment that allows a great condition to oral hygiene maintenance by the ...
