Reversible, non-plaque-induced marginal bone loss around an osseointegrated implant: A case report.

This case report documents a non-plaque-induced marginal bone loss around an osseointegrated implant. The loss of osseointegration, most likely caused by overload and/or suboptimal distribution of occlusal loading, may be reversed when the loading is reduced by optimally transmitting stress forces to the implant-to-bone interface and surrounding bone.

The effect of different cleansing methods for removing temporary cement on the tensile bond force of permanently cemented implant-supported metal copings: An in vitro study.

Objectives: Complete cleaning of temporary cement before permanent cementation of cement-retained implant-supported prosthesis (CISP) when recementing the crown is critical. This study evaluated the effect of different cleaning methods for removing traces of temporary cement on the final tensile bond force (TBF) of CISP recemented with resin cement.

Materials And Methods: Seventy computer-aided design/computer-aided manufacturing metal implant-supported copings were prepared and distributed into seven groups (N = 10).

When performing a frenectomy in patients with an increased risk of exposing bone dehiscence, it is essential that the distance between the incisions is not too wide and that they are mainly made in the movable mucosa to secure optimal wound closure.

An 8-10 Year Follow-up of Denture Satisfaction and Oral Health-Related Quality of Life with Implant-Retained Mandibular Overdentures.

Purpose: To report changes in denture satisfaction and oral health-related quality of life (OHRQoL) in edentulous patients treated with two-implant mandibular overdentures (IODs) over a follow-up of 8 to 10 years.

Materials And Methods: This is a follow-up of a previous study carried out between 1997 and 2005. The patients were originally randomly divided into one group receiving IODs and another group who had their conventional mandibular dentures relined (RCD group).

Ionizing radiation, genotoxic stress, and mitochondrial DNA copy-number variation in Caenorhabditis elegans: droplet digital PCR analysis.

Mitochondria are vulnerable to the effects of ionizing radiation; damage to mitochondrial DNA (mtDNA) may be more extensive and persistent than damage to nuclear DNA (nDNA). Variation in mtDNA copy number has been proposed as a marker for mitochondrial dysfunction in response to ionizing radiation. We have developed a precise and sensitive duplex droplet digital PCR (ddPCR) method for quantitation of the mtDNA/nDNA ratio in the model organism Caenorhabditis elegans.

Randomized controlled trial of the effectiveness of three different oral moisturizers in palliative care patients.

Most patients in palliative care have problems with dry mouth caused by medication or as a direct result of their condition. Dry mouth may cause problems that affect the primary disease negatively and contribute to poorer quality of life in palliative patients. This randomized controlled trial compared the efficacy of three different oral moisturizers: 17% watery solution of glycerol; oxygenated glycerol triester (marketed as Aequasyal in Europe and as Aquoral in the USA); and a newly developed product, Salient.

Rate of avoidable deaths in a Norwegian hospital trust as judged by retrospective chart review.

Background: The proportion of avoidable hospital deaths is challenging to estimate, but has great implications for quality improvement and health policy. Many studies and monitoring tools are based on selected high-risk populations, which may overestimate the proportion. Mandatory reporting systems, however, under-report.

Plasmid and Host Strain Characteristics of Escherichia coli Resistant to Extended-Spectrum Cephalosporins in the Norwegian Broiler Production.

Escherichia coli resistant to extended-spectrum cephalosporins have been detected in the Norwegian broiler production, despite the fact that antimicrobial agents are rarely used. The genetic mechanism responsible for cephalosporin resistance is mainly attributed to the presence of the blaCMY-2 gene encoding a plasmid-mediated AmpC-beta-lactamase (pAmpC). The aim of this study was to characterize and compare blaCMY-2 containing Escherichia coli isolated from the intestinal flora of broilers and retail chicken meat (fillets) to identify possible successful clones and/or resistance plasmids widespread in the Norwegian broiler production.

Evaluation of the ability of four ESBL-screening media to detect ESBL-producing Salmonella and Shigella.

Background: The aim of this study was to compare the ability of four commercially available media for screening extended-spectrum beta-lactamase (ESBL) to detect and identify ESBL-producing Salmonella and Shigella in fecal samples. A total of 71 Salmonella- and 21 Shigella-isolates producing ESBL(A) and/or AmpC, were received at Norwegian Institute of Public Health between 2005 and 2012. The 92 isolates were mixed with fecal specimens and tested on four ESBL screening media; ChromID ESBL (BioMèrieux), Brilliance ESBL (Oxoid), BLSE agar (AES Chemunex) and CHROMagar ESBL (CHROMagar).

Increased severity and mortality in adults co-infected with malaria and HIV in Maputo, Mozambique: a prospective cross-sectional study.

Background: Co-infection with falciparum malaria and HIV-1 increases the severity and mortality of both infections in unstable malaria-transmission areas. In contrast, in stable transmission areas, HIV co-infection increases the severity of both infections but has not been found to influence malaria mortality.

Methods: In a prospective cross-sectional study, clinical and laboratory data were consecutively collected for all adults admitted with fever and/or suspected malaria to the medical department of the Central Hospital of Maputo, Mozambique, during two malaria seasons from January 2011.

A critical appraisal of holistic teaching and its effects on dental student learning at University of Bergen, Norway.

The curriculum of the dental faculty at the University of Bergen, Norway, was revised and a new curriculum implemented in 1998 based on the principles of holistic teaching and patient-centered treatment. The first candidates graduated in 2003. The change of curricula, experience gained, and lack of an evidence base for holistic teaching justify a general discussion of all relevant aspects associated with this approach.

The influence of relining or implant retaining existing mandibular dentures on health-related quality of life: a 2-year randomized study of dissatisfied edentulous patients.

Purpose: The purpose was to assess and compare self-reported oral health and oral and general health related quality of life (OHRQoL and HRQoL) in two groups of edentulous adults who reported dissatisfaction with their mandibular dentures, and who were treated with a conventional relining of this denture or by having it converted into an implant-retained one.

Materials And Methods: Sixty subjects were randomly allocated into two equal groups, a relined conventional denture (RCD) group and an implant-retained overdenture (IOD) group. Data on demographics, oral health, OHRQoL, and HRQoL were recorded by means of a self-administered questionnaire at baseline, 3 months, and 2 years.
