PURPOSE The focus of this systematic review was to assess the published data concerning zirconia dental implant abutments from various aspects. MATERIALS AND METHODS To identify suitable literature, an electronic search was performed using PubMed. The keywords "zirconia," "zirconium," "ceramic," "dental abutments," "dental implants," "plaque," and(More)
The aims of this paper were to review the literature on shortened dental arches with special focus on publications of the Käyser/Nijmegen group, and to evaluate the discussions on the shortened dental arch concept found in the literature. A MEDLINE (PubMed) search was conducted for articles in English published in the dental literature from 1966 to November(More)
The aim of the present investigation was to study the influence of grain size on the strength of yttria-stabilized zirconia upon exposure to an additional heat treatment, mimicking the veneering process. The green bodies of zirconia discs prepared by cold isostatic pressing were sintered at 1,425, 1,500, or 1,575°C to customize the grain size. The(More)
BACKGROUND Acid electrolyzed water (AEW), which is produced through the electrolysis of dilute sodium chloride (NaCl) or potassium chloride solution, is used as a disinfectant in various fields because of its potent antimicrobial activity. The hydroxyl radical, an oxygen radical species, is often suggested as a putative active ingredient for AEW(More)
It is known that gallic acid shows antimicrobial activity. In the present study, photoirradiation induced reactive oxygen species formation was investigated for augmentation of the antimicrobial activity of gallic acid. Staphylococcus aureus suspended in 4 mmol/L gallic acid was exposed to blue light of a LED at 400 nm. This treatment killed the bacteria,(More)
The purpose of the present study was to evaluate the postantibiotic effect (PAE) of the disinfection treatment by photolysis of H2O2. Postantibiotic effect was induced in Staphylococcus aureus and Streptococcus salivarius by exposing the bacteria to H2O2 at concentrations of 250-1000 mmol/l, laser irradiation at a wavelength of 405 nm, and the combination(More)
Human oral polymorphonuclear cells (OPMNs) play an important role in the defence of oral cavity from bacteria by releasing reactive oxygen species (ROS). The purpose of the study is to determine ROS generated by OPMNs collected from healthy volunteers without any dental problems by applying a luminol analogue(More)
PURPOSE To review the clinical literature on fixed partial denture (FPD) and removable partial denture (RPD)treatment for periodontally compromised patients with partial dentate. In addition, prosthodontic management in periodontitis-susceptible subjects was evaluated from the results of Part 1 and Part 2. STUDY SELECTION Clinical studies that documented(More)
PURPOSE From a large number of experimental and clinical studies, it has been suggested that dental implant therapy has good prognosis for totally and partially edentulous patients. However, it is unclear whether we can use the implants for periodontally compromised patients. The aim of the present study was is to consider scientific evidence on implant(More)
