Platelet-rich fibrin (PRF) created by Choukroun's protocol concentrates most platelets and leukocytes from a blood harvest into a single autologous fibrin biomaterial. However, no current data is available concerning the use of PRF for the treatment of periapical lesions. Two cases of radicular cysts were reported using an interdisciplinary approach, including regular endodontic therapy followe...

At present, typical approaches employed to repair fractures and other bone lesions tend to use matrix grafts to promote tissue regeneration. These grafts act as templates, which promote cellular adhesion, growth and proliferation, osteoconduction, and even osteoinduction, which commonly results in de novo osteogenesis. The present work aimed to study the bone-repairing ability of hybrid matrixe...

Bioactive glass-ceramic nanoparticles (nBGC) may be produced using sol-gel methodologies. These nanobiomaterials may be used in a series of biomedical applications, such as tissue engineering of mineralised tissues. The preparation of nBGC and their properties are resumed. Example os applicability of nBGC in the orthopaedic field are presented, including in the preparation of scaffolds based on...

A Novel Bioactive Glass-Enhanced Orthodontic Bonding Resin: A shear bond strength study By Cole R. Johnson, D.D.S. A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Dentistry at Virginia Commonwealth University. Virginia Commonwealth University, 2011 Thesis Director: Eser Tüfekçi, D.D.S, M.S., Ph.D Associate Professor, Department of Orthodontic...

Background and Aim: This study aimed to compare the sorption and solubility properties of ACTIVA BioACTIVE liner and resin modified glass ionomer (RMGI).   Materials and Methods: In this in vitro study, a total of 30 samples were fabricated from each liner measuring 15 mm in diameter and 1 mm in thickness according to ISO 2009:4049. They were then divided into 6 subgroups (n=5) to assess th...

BACKGROUND AND PURPOSE Cementless total hip arthroplasty is currently favored by many orthopedic surgeons. The design of the porous surface is critically important for long-term fixation. We examined the clinical and radiographic outcome of the cementless titanium hip implant with a bottom coating of apatite-wollastonite containing bioactive glass ceramic. METHODS We retrospectively reviewed ...

The periodontium is a complex tissue consisting of soft and mineralized structures. Several diseases affect the integrity of periodontium causing the destruction of the connective tissue and cells. In recent decades bioactive glass has been used in several studies in the dental field because of its excellent regenerative properties. It is known that the effect of bioactive glass can be enhanced...

The potential use as a bone substitute material of a three-dimensional bioactive glass fiber scaffold composed of Na(2)O-K(2)O-MgO-CaO-B(2)O(3)-P(2)O(5)-SiO(2) (BG1) was investigated in this work. Scaffolds were pre-treated with simulated body fluid (SBF) to promote the formation of two different bone-like apatite layers on their surfaces. The topography and roughness of the deposited layers we...

OBJECTIVES The purpose of this study was to evaluate the changes in dentinal permeability (i.e. hydraulic conductance) after prophylactic treatment performed using prophy-powders with air-polishing system or prophy-pastes applied on exposed middle dentine. The changes in dentine morphology were evaluate by SEM. STUDY DESIGN Several prophylactic pastes or air-polishing powders were tested in t...

PURPOSE To compare histometrically, in rats, the bone healing after grafting the incisor extraction sockets with inorganic bovine bone or bioactive glass particles. MATERIAL The volume fraction of grafted materials and alveolar healing components was estimated in histologic images at the end of the second and ninth weeks postoperatively by a differential point-counting method. RESULTS Both ...
