Dental Implant Abutment Screw Loss: Presentation of 10 Cases.

Re-tightening the loosened dental implant abutment screw is an accepted procedure, however the evidence that such screw will hold sufficiently is weak. The purpose of this study was material analysis of lost dental implant abutment screws made of the TiAlV alloy from various manufacturers, which became lost due to unscrewing or damaged when checking if unscrewed; undamaged screws could be safely re-tightened. Among 13 failed screws retrieved from 10 cases, 10 screws were removed due to untightening and 3 were broken but without mechanical damage at the threads.

The Effect of Exposure to Candida Albicans Suspension on the Properties of Silicone Dental Soft Lining Material.

While functioning in the oral cavity, denture soft linings (SL) are exposed to contact with the microbiota. Dentures can offer perfect conditions for the multiplication of pathogenic yeast-like fungi, resulting in rapid colonisation of the surface of the materials used. In vitro experiments have also shown that yeast may penetrate SL.

The effect of porous compliance bushings in a dental implant on the distribution of occlusal loads.

Porous dental implants are clinically used, but the mechanism of load distribution for stepped implant shaft surrounded by compliance bushings is still not known, especially for different bone conditions. The aim of the study was to assess the impact of the design of a dental implant with compliance bushings (CBs) on the occlusal load distribution during primary and secondary stability using finite element simulation (FEA), with a distinction between low and high quality cervical support under primary stability. The FEA of the oblique occlusal load transfer (250 N; 45°) was carried out for implants under variable bone conditions.

What is a biosecurity measure? A definition proposal for animal production and linked processing operations.

While biosecurity, a central component of the One Health concept, is clearly defined, a harmonized definition of the term ´biosecurity measure´ (BSM) is missing. In turn, particularly at the farm and policy level, this leads to misunderstandings, low acceptance, poor implementation, and thus suboptimal biosecurity along the food animal production chain. Moreover, different views on BSMs affects making comparisons both at the policy level as well as in the scientific community.

Non-Invasive Sampling in the Aspect of African Swine Fever Detection-A Risk to Accurate Diagnosis.

African swine fever remains one of the most economically important and dangerous diseases of the family. Until now, neither a safe vaccine nor a treatment against ASF has been available, which is why prevention of the disease involves biosecurity measures and early recognition based on accurate diagnosis. Nowadays, different strategies for ASF detection are discussed to reduce both animal suffering and the costs of ASF surveillance.

In total, 64 patients with clinical TMD were examined.

Temporal trends (1953-2012) of toxic and essential elements in red deer antlers from northeastern Poland.

Red deer antlers have a number of advantages that make them a unique material for monitoring trace elements. As antlers are shed and regrown every year, results of toxicological investigations can be applied to a particular region and time. We analyzed the content of four toxic (Pb, Cd, Hg, As) and three essential (Cu, Zn, Fe) trace elements in 254 red deer antler samples spanning between 1953 and 2012.

and Antimicrobial Resistance in Wild Rodents-True or False Threat?

Transmission of pathogenic and resistant bacteria from wildlife to the bacterial gene pool in nature affects the ecosystem. Hence, we studied intestine content of five wild rodent species: the yellow-necked wood mouse (, = 121), striped field mouse (, = 75), common vole (, = 37), bank vole (, = 3), and house mouse (, = 1) to assess their potential role as an antimicrobial resistance (AMR) and vector. The methods adopted from official AMR monitoring of slaughtered animals were applied and supplemented with colistin resistance screening.

Total mercury levels in the muscle and liver of livestock and game animals in Poland, 2009-2018.

The bioaccumulation of mercury (Hg) in the food chain may pose a threat to human health. The risk of dietary Hg intake is mostly caused by the consumption of fish and seafood, therefore the knowledge on the exposure from land animal products is limited. In our article, we summarized the results of analyses of Hg in muscle tissue and liver of different livestock and game animals obtained during ten years of official monitoring that was carried out in Poland from 2009 to 2018.

The Prevalence of and in Small Wild Rodents in Poland.

Use of finite element analysis for the assessment of biomechanical factors related to pain sensation beneath complete dentures during mastication.

Statement Of Problem: The pain commonly suffered by denture wearers during mastication is not documented in the objective biomechanical criteria for the pressure pain threshold.

Purpose: The purpose of this finite element analysis study was to determine whether the pressures developed beneath a removable mandibular complete denture during mastication would exceed the average pressure pain threshold in patients for whom the denture foundation had an acceptable load-bearing capacity.

Material And Methods: A patient with an acceptable load-bearing denture foundation was modeled with finite element analysis.

Seroprevalence of 12 serovars of pathogenic Leptospira in red foxes (Vulpes vulpes) in Poland.

Background: Leptospira spp. infect humans and a wide range of domestic and wild animals, but certain species such as small rodents and red foxes (Vulpes vulpes) play a particular role as reservoirs and transmission of leptospirosis as they easily adapt to many habitats including human environments. To investigate the significance of red foxes in the epidemiology of leptospirosis in Poland, a seroprevalence survey was conducted.

Relevance of Tongue Force on Mandibular Denture Stabilization during Mastication.

Purpose: Tongue activity, involving stereognosis of denture position, food bolus distribution, and direct denture pressing, can affect the stability of removable mandibular dentures. Knowledge of details of tongue activity in patients with removable dentures could contribute to the development of training methods to improve bilateral mastication. The hypothesis of this study was that tongue force improves mandibular complete denture stabilization on the atrophied foundation during mastication load transfer with a typical balanced occlusion.

The effect of diet enriched with rapeseed meal on endogenous thiouracil contents in urine and milk of cattle.

Thyreostatic compounds, such as thiouracil, are orally active drugs that can be used to increase the weight of cattle before slaughter. Due to potentially teratogenic and carcinogenic effects of their residues on public health, the use of thyreostats in animal production has been banned in the European Union since 1981. Systematic detection of low concentrations of thiouracil in the urine of livestock in many countries is believed to be of endogenous origin due to the use of Brassicaceae plants in the animal diet.
