This study was carried out in order to determine the efficacy of CaO-P2O5-MgO-SiO2-CaF system glass ceramics, which are made as implant materials, for treatment of furcation lesions. Glass ceramic granules were implanted in artificial class II furcation bony defects in monkeys. As controls, non-implanted sites were preserved. Radiographic and various clinical examinations were performed before ...

Aim: To evaluate the accuracy of panoramic radiography in determining dentin thickness danger zone (DZ) using cone-beam computed tomography (CBCT) imaging to examine thicknesses mandibular molars at different levels. Materials and Methods: For study, 250 were selected. Dentine measured on radiography. On CBCT view, dentine mesiobuccal (MB), mesiolingual (ML), distal roots measured. The referenc...

this study aimed to compare the efficacy of mta and cem cement in class ii furcation defects in human mandibular molars.forty furcation defects were treated in 16 patients with chronic periodontitis. the clinical parameters of probing depth (pd), vertical and horizontal clinical attachment levels (vcal and hcal), open vertical and horizontal furcation depths (ovfd and ohfd), and gingival margin...

The purpose of this study was to evaluate the ability of gray and white ProRoot MTA to seal furcation perforations in mandibular molars using a dye extraction leakage model. Sixty-four mandibular molars were randomly divided into four experimental groups. Six teeth with perforations were used as positive controls and six teeth without perforations were used as negative controls. Perforations in...

This paper presents a case series of furcation involved teeth complicated with endodontic involvement which were treated with periodontal, endodontic and restorative procedures using different bone regenerative materials like; (a) Calcium phosphosilicate bone substitute having bioactive glass 69% mixed with glycerin 19% and poly-ethylene 12% dispensed in a putty form; (b) hydroxyapatite 70% and...

Two molars having furcation grade II involvements were selected from each of six patients with periodontal diseases. One molar received a local application of tetracycline immobilized cross-liked collagen film four times at one-week intervals (TC film-treated group) and the other received no treatment (non-treated group). The clinical and microbiological effects were, as follows, 1. Throughout ...

We study the scaling behavior of M -furcation (M =2, 3, 4, . . .) sequences of M-period (n = 1, 2, . . .) orbits in two coupled one-dimensional (1D) maps. Using a renormalization method, how the scaling behavior depends on M is particularly investigated in the zero-coupling case in which the two 1D maps become uncoupled. The zero-coupling fixed map of the M -furcation renormalization transforma...

The aim of this study was to investigate the effect of the pore characteristics of β-tricalcium phosphate (β-TCP) on periodontal healing in class III furcation defects in dogs. Two types of β-TCP were prepared for grafting; 1) a tunnel pipe structure with an inner diameter of 300 μm, and 2) continuous pore structure with interconnected macropores. The furcations of thirty mandibular premolar te...
