Copper Accumulation in the Lips of Brass Players: Case Report of a Rare Phenomenon.

Work-related exposures affecting oral health are important factors of morbidity and decreased quality of life, which may emerge from numerous physical, chemical, or mental occupational exposures. Copper (Cu) is an important trace element, however, it may also cause allergies, depose and accumulate in the body, leading to acute and chronic toxicity. In the present report, we describe a rare phenomenon found during the examination of two professional brass players, after incidentally noting an artefact during magnetic resonance imaging (MRI) scans, which were performed to monitor bone healing after bone augmentation procedures in an unrelated clinical study.

Biomechanical properties of the bone during implant placement.

Background: In this research the biomechanical properties of a bone model was examined. Porcine ribs are used as experimental model. The objective of this research was to investigate and compare the biomechanical properties of the bone model before and after implant placement.

Within-litter covariance of allele-specific MHC heterozygosity, coccidian endoparasite load and growth is modulated by sibling differences in starting mass.

Although littermates in altricial mammals usually experience highly similar environmental conditions during early life, considerable differences in growth and health can emerge among them. In a study on subadults of a European rabbit (Oryctolagus cuniculus) population with low MHC polymorphism, we tested whether litter-sibling differences in endoparasitic coccidia load and body mass at the end of the vegetation period were associated with within-litter differences in starting body mass (measured around 2 weeks prior to weaning) and in immune-genetic (MHC class II DRB) constitution. We hypothesized that siblings with a lighter starting mass might be more susceptible to endoparasite infections and thus, negative effects of a more unfavourable MHC constitution might be particularly pronounced in such individuals.

[Effect of the treatment of periodontal disease on the outcome of pregnancy].

Introduction: Correlations between periodontitis and its effects on the outcome of pregnancies are actually more focused topics. Maternal motivation for a good oral hygiene and preventive dental treatment must be highlighted tasks during pregnancy care.

Aim: The authors analysed the effect of the preventive dental treatment during pregnancy and its obstetrical effects.

Change in the Caries Status of Pregnant Women in Southeast Hungary and Its Background.

Purpose: To examine the caries status of pregnant women in southeast Hungary and compare the results with a similar study completed in the same region ten years earlier to determine whether any improvement has taken place in the past decade. Another objective was to assess the effects of age, socioeconomic status and number of pregnancies on oral health.

Materials And Methods: The dental examination of 130 pregnant women was carried out at the Dental Clinic of University of Szeged, Faculty of Dentistry in 2011-2013 (group 1).
