    Abstract Aim: There is evidence that regenerative treatment of intra-bony and mandibular class II furcation defects with access flap and an application of an enamel matrix protein derivative (EMD) can result in a clinical benefit compared with access flap alone. The aim of this pilot study was to check if the results of access flap surgery in suprabony defects are improved by additional application of EMD. Material and Methods: Thirty-nine adult subjects with supra-alveolar-type defects were randomly assigned to a test (n=25) and a control group (n=14). Seventy teeth were treated with EMD; 28 teeth were treated by access flap. Probing depth (PD), clinical attachment level and bleeding on probing were evaluated at baseline and after 12 months. Results: PD of the operated teeth was improved in both groups (p<0.001 to p=0.041) but always better in the test group. The attachment gain was 2.72±1.80 mm at sites with an initial PD 7 mm in the test group and 0.78±0.62 mm in the control group (p=0.004). In the test group the mean attachment gain was 0.97±0.92 mm (p<0.001); the mean reduction of PD was 1.55±0.90 mm (p<0.001). Conclusions: The data suggest a significant clinical benefit of supplementary application of EMD during surgical treatment of periodontitis of supra-alveolar pockets, especially in deeper pockets.

    Abstract Objective: A combination of platelet-rich plasma (PRP), bovine porous bone mineral (BPBM) and guided tissue regeneration (GTR) has been shown to be effective as regenerative treatment for intrabony periodontal defects. The purpose of this study was to evaluate the effectiveness of PRP, BPBM and GTR used in combination as regenerative treatment for grade II molar furcation defects in humans. Material and methods: Using a split-mouth design, a total of 52 grade II mandibular molar furcation defects were treated either with PRP/BPBM/GTR (experimental group, n=26) or with an open flap debridement (control group, n=26). The primary outcomes evaluated in this study included changes in pocket depth, attachment level and re-entry bone levels (horizontal and vertical) between baseline and 6 months postoperatively. Results: The results showed that the experimental group presented with significantly greater pocket reduction (4.07±0.33 mm for experimental and 2.49±0.38 mm for control sites), gain in clinical attachment (3.29 ± 0.42 mm for experimental and 1.68±0.31 mm for control sites), vertical defect fill (2.56± 0.36 mm for experimental and ,0.19±0.02 for control sites) and horizontal defect fill (2.28±0.33 mm for experimental and 0.08±0.02 mm for control sites) than the control group. Conclusions: It was concluded that the PRP/BPBM/GTR combined technique is an effective modality of regenerative treatment for mandibular grade II furcation defects. Further studies are necessary to elucidate the role played by each component of the combined therapy in achieving these results. Zusammenfassung Ziel: Eine Kombination von plättchemreichen Plasma (PRP), bovinem porösem Knochenmineral (BPBM) und gesteuerter Geweberegeneration (GTR) wurde als effektiv bei der regenerativen Behandlung von intraalveolären parodontalen Knochendefekten gezeigt. Der Zweck dieser Studie war die Evaluation der Effektivität von PRP, BPBM und GTR in der Kombination als regenerative Behandlung für Grad II Furkationsdefekte bei menschlichen Molaren. Material und Methoden: Unter Nutzung eines split-mouth Design wurden 52 Grad II Unterkiefermolaren Furkationsdefekte entweder mit PRP/BPBM/GTR (experimentelle Gruppe, n=26) oder mit einer offenen Reinigung (Lappenoperation) (Kontrollgruppe, n=26) behandelt. Die primären Ergebnisse die in dieser Studie evaluiert wurden, bezogen die Veränderung der Sondierungstiefen, des Stützgewebeniveaus und des Knochenniveaus bei reentry-Operationen (horizontal und vertikal) zwischen Basis und 6 Monate post operationem ein. Ergebnisse: Die Ergebnisse zeigten, dass die experimentelle Gruppe eine höhere Reduktion der Sondierungstiefen (4.07±0.33 mm für experimentelle und 2.49±0.38 mm für Kontrollflächen), einen höheren Stützgewebegewinn (3.29±0.42 mm für experimentelle und 1.68± 0.31 mm für Kontrollflächen), eine größere vertikale Defektfüllung (2.56±0.36 mm für experimentelle und ,0.19±0.02 für Kontrollflächen) sowie horizontale Defektfüllung (2.28± 0.33 mm für experimentelle und 0.08±0.02 mm für Kontrollflächen) verglichen mit den Kontrollen zeigte. Schlussfolgerungen: Es wird gefolgert, dass die Kombination von PRB/BPBM/GTR eine effektive Modifikation der regenerativen Behandlung bei Grad II Furkationsdefekten bei unteren Molaren ist. Weitere Studien sind notwendig, um die Rolle jeder Komponente dieser kombinierten Therapie in der Erzielung dieser Ergebnisse zu erfassen. Résumé Objectif: Une combinaison de plasma riche en plaquette (PRP), de minéral d'os bovin poreux (BPBM) et de régénération tissulaire guidée (GTR) a prouvé son efficacité en tant que traitement régénératif pour les lésions intra-osseuses parodontales. Cette étude se propose d'évaluer l'intérêt de l'utilisation en combinaison de PRP, BPBM et GTR comme traitement de régénération des lésions furcatoires molaires de classe II chez l'homme. Matériels et Méthodes: Par une étude conçue en bouche croisée, 52 lésions furcatoires molaires mandibullaires ont été traitées soit avec PRP/BPBM/GTR (groupe expérimental, n=26) ou par simple lambeau d'accès (groupe contrôle, n=26). Les objectifs primaires évalués dans cette étude étaient la modification de la profondeur de poche, le niveau d'attache et les niveaux osseux lors de la réentrée (en horizontal et en vertical) mesurés six mois post-op. Résultats: les résultats montrent que le groupe expérimental présentait significativement une plus importante réduction de poche (4.07±0.33 mm contre 2.49±0.38 mm pour les sites contrôles), un gain d'attache clinique plus important (3.29± 0.42 mm contre 1.68±0.31 mm pour les sites contrôles), un comblement vertical des lésions(2.56±0.36 mm contre ,0.19±0.02 pour les sites contrôles) et un comblement horizontal des lésions (2.28±0.33 mm contre 0.08± 0.02 mm pour les sites contrôles). Conclusions: Nous en concluons que la technique combinant PRP/BPBM/GTR est un traitement régénératif efficace pour les lésions de furcation molaire mandibulaire de classe II. Des études complémentaires sont nécessaires pour élucider le rôle joué par chaque élément de cette combinaison dans l'obtention de ces résultats. [source]

    Several growth factors (or cytokines) have been recently investigated for their use as potential therapeutics for periodontal tissue regeneration. The objective of this study was to evaluate periodontal tissue regeneration, including new bone and cementum formation, following topical application of recombinant basic fibroblast growth factor (bFGF, FGF-2) to furcation class II defects. Twelve furcation class II bone defects were surgically created in six beagle dogs, then recombinant bFGF (30 µg/site) + gelatinous carrier was topically applied to the bony defects. Six weeks after application, periodontal regeneration was analyzed. In all sites where bFGF was applied, periodontal ligament formation with new cementum deposits and new bone formation was observed histomorphometrically, in amounts greater than in the control sites. Basic FGF-applied sites exhibited significant regeneration as represented by the new bone formation rate (NBR) (83.6 ± 14.3%), new trabecular bone formation rate (NTBR) (44.1 ± 9.5%), and new cementum formation rate (NCR) (97.0 ± 7.5%). In contrast, in the carrier-only sites, the NBR, NTBR, and NCR were 35.4 ± 8.9%, 16.6 ± 6.2%, and 37.2 ± 15.1%, respectively. Moreover, no instances of epithelial down growth, ankylosis, or root resorption were observed in the bFGF-applied sites examined. The present results indicate that topical application of bFGF can enhance considerable periodontal regeneration in artificially created furcation class II bone defects of beagle dogs. [source]

    Abstract Background:, The aim of this study was to compare the clinical outcomes of applying Bio-Oss®, an anorganic bovine bone xenograft (control group) to the combined use of Bio-Oss® and Bio-Gide® (a bioabsorbable collagen membrane) (test group) in human mandibular Class II furcation defects. Methods:, A total of 18 furcations (8 tests and 10 controls) in 14 patients suffering from chronic periodontitis were treated in this randomized clinical trial. Open vertical and horizontal furcation depths (OVFD and OHFD), vertical and horizontal clinical attachment levels (VCAL, HCAL), probing depth (PD) and free gingival marginal level (GML) were among the clinical parameters measured prior and six months after treatment, at re-entry surgery. The data were analysed by statistical tests while a p value less than 0.05 was considered significant. Results:, At the surgical re-entry, the mean reduction for OVFD of the control and test groups was 1.9 ± 1.3 and 2.1 ± 1.0, and for OHFD 2.1 ± 0.7 and 2.4 ± 1.3, respectively. The control and test treatments resulted in significant reductions in PD, VCAL and HCAL measurements at re-entry but there was no statistically significant difference between the two treatments in all soft and hard tissues measurements. Conclusions:, This clinical trial failed to demonstrate the superiority of the combined use of Bio-Gide® and Bio-Oss® to the use of Bio-Oss® alone, although both therapies resulted in significant gains in attachment level and bone fill.
