Introduction. Despite great progress in the diagnostics and treatment, breast cancer still remains the most frequently diagnosed malignant cancer in women. The outcomes of cancer treatment depend, to a considerable extent, on the degree of acceptance of the illness. The objective of the study was determination of the level of acceptance of the disease among the examined women with breast cancer. Materials and method. The study covered a group of 231 women who received treatment for breast cancer in the Rev. Bronislaw Markiewicz Subcarpathian Oncology Centre in Brzozow, south-eastern Poland, and conducted by the method of a diagnostic survey, using an author constructed questionnaire and the standard Acceptance of Illness Scale, adapted by Z. Juczyński. Statistical analyses were performed using the software IBM SPSS v. 21.0.0.1. The p values p≤0.05 were considered statistically significant. Results. The mean level of acceptance of the illness in the examined group of women was 26.53 (SD = 7.71; Me = 26). The largest number of respondents (50.6%) obtained scores within the range of 20-29, according to the AIS Scale. From among the adopted variables, the level of acceptance of the illness significantly varied according to age and occupational activity. However, no such differences were confirmed according to the place of residence, marital status, education level, or the type of occupation performed. Conclusions. In the examined group of women, a mediocre level of acceptance of cancer was observed. The respondents' age and occupational situation exerted a significant effect on the level of acceptance of the illness. The results of the study should be considered as satisfactory because the number of women with a high level of acceptance of breast cancer was more than twice as high as those ones with a low acceptance of the disease.

Porosity is an important parameter for characterizing the microstructure of solids that corresponds to the volume of the void space, which may contain fluid or air, over the total volume of the material. Many materials of natural and technically manufactured origin have a large number of voids in their internal structure, relatively small in size, compared to the characteristic dimensions of the body itself. Thus, porosity is an important feature of industrial materials, but also of biological ones. The porous structure affects a number of material properties, such as sorption capacity, as well as mechanical, thermal, and electrical properties. Porosity of materials is an important factor in research on biomaterials. The most popular materials used to rebuild damaged tooth tissues are composites and ceramics, whilst titanium alloys are used in the production of implants that replace the tooth root. Research indicates that the most comprehensive approach to examining such materials should involve an analysis using several complementary methods covering the widest possible range of pore sizes. In addition to the constantly observed increase in the resolution capabilities of devices, the development of computational models and algorithms improving the quality of the measurement signal remains a big challenge.

Enamel, dentin and cementum apatite has a complex composition. The lack of complete reports on the chemical composition of all tooth tissues together and the need to create a modern biomaterial that reproduces the correct ratio of individual tooth mineral components prompted the authors to undertake the research. A detailed evaluation of the micro- and macro-elements of tooth powder, using various methods of chemical analysis was conducted. All four groups of human sound teeth were crushed using the grinder. A fine powder was implemented for the FTIR (Fourier Transform Infrared Spectroscopy), ICP (Inductively Coupled Plasma Optical Emission Spectometry) and for the potentiometric titration, SEM and mercury porosimetry analyses. The obtained studies indicate that there is no significant correlation in chemical composition between the different teeth types. This proves that every removed, crushed tooth free of microorganisms can be a suitable material for alveolar augmentation. It is essential to know the chemical profiles of different elements in teeth to develop a new class of biomaterials for clinical applications.
