Microbiota of the Dorsum of the Tongue After Plaque Accumulation: An Experimental Study in Humans
Journal of Periodontology - Tập 77 Số 9 - Trang 1539-1546 - 2006
Marcelo Faveri, Magda Feres, Jamil Awad Shibli, Roberto F. Hayacibara, Mitsue Fujimaki, Luciene Cristina Figueiredo
Background: The purpose of the present investigation was to determine the effect of the absence of tongue hygiene on the microbiota of the dorsum of the tongue.Methods: Ten volunteers (aged 19 to 22 years) entered the study at baseline and were instructed to abstain from tongue cleaning for 7 days, followed by a period of 3 day...... hiện toàn bộ
Evaluation of Pluronic Polyols as Carriers for Grafting Materials: Study in Rat Calvaria Defects
Journal of Periodontology - Tập 73 Số 2 - Trang 191-197 - 2002
Edward B. Fowler, Michael F. Cuenin, Steven D. Hokett, Mark E. Peacock, James C. McPherson, Thomas R. Dirksen, Mohamed Sharawy, Michael A. Billman
Background: Pluronic polyols are a family of non‐ionic surfactants currently used as drug carriers for antibiotic, anti‐inflammatory, and anti‐neoplastic agents. Therapeutic administration of non‐ionic surface‐active agents is known to facilitate early collagen synthesis and microcirculation, thus promoting wound healing. The purpose of this study was to determine th...... hiện toàn bộ
The Causes of Early Implant Bone Loss: Myth or Science?
Journal of Periodontology - Tập 73 Số 3 - Trang 322-333 - 2002
Tae‐Ju Oh, Joongkyo Yoon, Carl E. Misch, Hom‐Lay Wang
The success of dental implants is highly dependent on integration between the implant and intraoral hard/soft tissue. Initial breakdown of the implant‐tissue interface generally begins at the crestal region in successfully osseointegrated endosteal implants, regardless of surgical approaches (submerged or nonsubmerged). Early crestal bone loss is often observed after the first...... hiện toàn bộ
The Osteogenic Potential of Two Human Demineralized Bone Preparations Using a Xenogeneic Model
Journal of Periodontology - Tập 60 Số 1 - Trang 12-18 - 1989
Kenneth W. Marinak, James T. Mellonig, Herbert J. Towle
The relative osteogenic potential of two different preparations of lyophilized human demineralized bone were evaluated using a heterotopic site in a rodent model. Human diaphyseal cortical bone (75‐850 μm) was demineralized according to two different protocols for decalcified bone allograft (A. H. Reddi and M. R. Urist). Equal volumes of mineralized lyophilized human bon...... hiện toàn bộ
Antigenicity of Freeze‐Dried Cortical Bone Allograft in Human Periodontal Osseous Defects
Journal of Periodontology - Tập 59 Số 6 - Trang 394-397 - 1988
J. Bryan Quattlebaunr, James T. Mellonig, Nancy F. Hensel
The purpose of this investigation was to determine whether donor‐specific anti‐HLA antibodies could be detected against freeze‐dried cortical bone allograft (FDBA) placed in human periodontal osseous defects. Twenty patients with multiple periodontal bony defects amenable to treatment in two allografting procedures were enrolled. No patient had preexisting anti‐HLA antib...... hiện toàn bộ
Blur Reduction of Conventional Film‐Based Tomograms For Pre‐Surgical Evaluation of Potential Mandibular Implant Sites
Journal of Periodontology - Tập 68 Số 4 - Trang 362-368 - 1997
T Mayfield-Donahoo, Ernest M. Stokely, Matthew Doyle
The usefulness of motion‐based cross‐sectional tomography to evaluate osseous support and adjacent anatomical structures for dental implant placement is limited by the inherent blurring in these images. The goal of this study was to develop a method to remove blurring while permitting accurate dimensional analysis of the potential implant site. Defined regions (anterior,...... hiện toàn bộ
Intragingival Occurrence of Actinobacillus actinomycetemcomitans and Bacteroides gingivalis in Active Destructive Periodontal Lesions
Journal of Periodontology - Tập 59 Số 4 - Trang 259-265 - 1988
F. R. Saglie, A. Marfany, Paulo M. Camargo
A total of six active and six nonactive sites from six untreated Periodontitis patients were examined for intragingival presence of Actinobacillus actinomycetemcomitans and Bacteroides gingivalis. The active destructive periodontal disease was determined by the “tolerance method.” The method of immunoperoxidase was us...... hiện toàn bộ
Soft Tissue Augmentation Using Silk Gels: An In Vitro and In Vivo Study
Journal of Periodontology - Tập 80 Số 11 - Trang 1852-1858 - 2009
Etienne Olivier, Aurore Schneider, Jonathan A. Kluge, Claire Bellemin‐Laponnaz, Camille Polidori, Gary G. Leisk, David L. Kaplan, William P. Meehan, Christophe Egles
Background: Restoration of a three‐dimensional shape with soft tissue augmentation is a challenge for surgical reconstruction and esthetic improvement of intraoral mucosa and perioral skin tissues. A connective tissue graft or free gingival graft, classically used for such indications, requires a donor site, which may lead to various clinical complications.<...... hiện toàn bộ
Osteogenesis Enhanced by Chitosan (Poly‐N‐Acetyl Glucosaminoglycan) In Vitro
Journal of Periodontology - Tập 67 Số 11 - Trang 1170-1175 - 1996
Perry R. Klokkevold, Lorese Vandemark, E. Barrie Kenney, George W. Bernard
Chitosan, with a chemical structure similar to hyaluronic acid, has been implicated as a wound healing agent. The purpose of this research was to evaluate the effect of chitosan on Osteoblast differentiation and bone formation in vitro. Mesenchymal stem cells were harvested from fetal Swiss Webster mice calvariae prior to osteoblast differentiation and calcification (12 ...... hiện toàn bộ
Connective Tissue Growth Factor in Drug‐Induced Gingival Overgrowth
Journal of Periodontology - Tập 72 Số 7 - Trang 921-931 - 2001
M. Ilhan Uzel, Alpdoğan Kantarcı, Hsiang‐Hsi Hong, Cem Uygur, M Sheff, Erhan Fıratlı, Philip C. Trackman
Background: Drug‐induced gingival overgrowth is a known side effect of certain chemotherapeutic agents used for the treatment of systemic disorders. The pathogenesis and mechanisms responsible for this condition are not fully understood. This study assesses for the presence and localization of connective tissue growth factor (CTGF) in drug‐induced gingival overgrowth...... hiện toàn bộ
