Introduction. Higher education institutions thoroughly analyze the labor market. Knowing the career plans of students is important information showing the potential and direction of development of the labor market. Aim The aim of the study was to gather information on career plans and further development of graduates of the Division of Dentistry, Medical University of Lublin in the years 2004-2012. Material and methods The survey covered a group of 743 graduates of medical-dental faculty. Students filled in an anonymous questionnaire after passing the exam in conservative dentistry with endodontics. The questions concerned the location and nature of future work, as well as the desire to specialize and determining the area in which the graduate is planning to specialize. Results The question: “Where are you planning to start work after graduation?” – was answered by more than 35% of the students: “In a big city outside of Lublin.” Over 24% of respondents expressed a desire to return to their hometown, and 21% declared remaining in Lublin. Approximately 13.6% of respondents were considering going abroad, and about 5.65% of the students declared choosing village or a small town, as a place for future work. Among all graduated students, 45.5% would like to work in a medical joint venture, 38.5% wishing to undertake business activity in their own dental office. Only 7.4% of students declared their desire to remain at the university and carry out scientific work. The vast majority of graduates (87.35%) expressed the desire for specialization. The most frequently indicated specialization was conservative dentistry with endo-dontics – the choice was indicated by 22.62% of the respondents. Students expressed similar interest in further development in the field of oral surgery (20.33%), prosthodontics (20.33%) and orthodontics (18.58%). Conclusions Most of the students of dental-medical major of Medical University of Lublin after graduation planned to work in Poland. The respondents were planning to work primarily in medical partnerships or to open their own dental offices. The vast majority of respondents declared a desire to get specialization.

We determined the in vitro corrosion resistance of the composite chitosan-silver(I) [Ag(I)] ion coating on the cobalt-chromium-molybdenum (CoCrMo) dental alloy in a 0.9% sodium chloride (NaCl) solution at 37°C. We obtained the novel composite chitosan–Ag(I) ion coating by electrophoretic deposition at 20 V for 30 s at room temperature in a 2% (v/v) aqueous solution of acetic acid with 1 g dm–3 chitosan and 10 g dm–3 silver nitrate. We evaluated the chemical composition with energy dispersive spectroscopy and Fouriert-ransform infrared spectroscopy. We investigated surface topography and electronic properties with a scanning Kelvin probe. We determined the mechanism and kinetics of the electrochemical corrosion of the obtained coatings by electrochemical impedance spectroscopy. The Ag content in the composite chitosan–Ag(I) ion coating was 1.9 ± 1 wt.%. The cataphoretic co-deposition of chitosan and Ag(I) ions in an aqueous solution can be used to modify the CoCrMo alloy surface to obtain new coatings with antibacterial properties.

The objective of this work was to define the different criteria that a general dentist will have to take into account to equip himself with a three-dimensional (3D) printer for dental use. We have identified a total of 1037 3D printers produced by 342 companies and 211 3D printers from 88 companies that can print with 25µm layers. To be able to compare them, we evaluated 16 different characteristics: 1) family of 3D printing process, 2) minimum layer thickness, 3) presence or absence of scientific study to validate the minimum layer thickness, 4) minimal resolution on XY axes, 5) type of calibration, 6) printing environment, 7) presence of a heated printing plate, 8) maximum printing speed (in mm/s) with a link giving details of the layer thickness used, the XY resolution used and the material used to determine this speed, 9) dimensions of printing capacity, 10) capacity to use materials not originating from the manufacturer, 11) capacity to use biocompatible materials, 12) weight (in kg) and printer dimensions (in cm), 13) compatible operating systems, 14) compatible 3D print file types, 15) after-sales service and warranty period, 16) price, including whether taxes are included s or not. We noted a great heterogeneity of the information present, and information often absent regarding: 1) the type of calibration, 2) the printing speed, 3) the price, 4) the after-sales service, 5) the guarantee as well as 6) the materials which are taken into account by the 3D printer. We described multiple communication difficulties with our contacts and a very dynamic development of the 3D printing world. Finally, we proposed the characteristics of an "ideal" dental 3D printer and of an "ideal" partner company for a dentist wishing to obtain the 3D printer of his choice.

L’objectif de ce travail est de définir les différents critères qu’un dentiste généraliste doit prendre en compte pour s’équiper d’une imprimante tridimensionnelle (3D) à usage dentaire. Nous avons recensé au total 1037 imprimantes 3D produites par 342 entreprises et 211 imprimantes 3D de 88 entreprises pouvant imprimer avec des couches de 25µm. Pour pouvoir les comparer nous avons évalué 16 caractéristiques différentes: 1) famille de procédé d’impression 3D, 2) épaisseur de couche minimale, 3) présence ou non d’étude scientifique de validation de l’épaisseur de couche minimale, 4) résolution XY minimale, 5) type de calibrage, 6) environnement d’impression, 7) présence d’un plateau d’impression chauffant, 8) vitesse d’impression maximale (en mm/s) avec un lien donnant le détail de l’épaisseur de couche utilisée, de la résolution XY utilisée et du matériau utilisé pour déterminer cette vitesse, 9) dimensions de capacité d’impression, 10) capacité d’utiliser des matériaux ne provenant pas de l’entreprise constructrice, 11) capacité d’utiliser des matériaux biocompatibles, 12) poids (en kg) et dimensions de l’imprimante (en cm), 13) systèmes d’exploitation compatibles, 14) types de fichier d’impression 3D compatibles, 15) gestion du service après-vente et durée de la garantie, 16) prix, en indiquant si les taxes sont incluses ou non. Nous avons constaté une grande hétérogénéité des informations présentes et des informations souvent absentes en ce qui concerne : 1) le type de calibrage, 2) la vitesse d’impression, 3) le prix, 4) le service après-vente, 5) la garantie ainsi que 6) les matériaux qui sont pris en compte par l’imprimante 3D. Nous avons décrit des difficultés de communication multiples avec nos interlocuteurs et un développement très dynamique du monde d’impression 3D. Enfin, nous avons proposé des caractéristiques d’une imprimante 3D dentaire « idéale » et d’une entreprise-partenaire « idéale» pour un dentiste désireux de se procurer l’imprimante 3D de son choix.

Aim of the study. The objective of the present study was to assess the occurrence of pain, ergonomic skills in the dental workplace and the frequency of health-promoting behaviour among dentists. Material and methods. The survey was based on an anonymous questionnaire. The group comprised 223 dentists (172 women and 51 men). The respondents gave answers to 3 groups of questions covering demographic data, working methods, experience of pain and the methods dentists used to treat such pain. Results. The survey confirmed that the occurrence of pain in the musculoskeletal system is a universal problem. The cause lies in the failure of dentists to observe the basic rules of ergonomics as well as poor work organisation. 81.86% of dentists and 19.13% of graduate dentists reported musculoskeletal pain over the course of the previous 12 months. Chronic pain affected 30.09% of the respondents. Pain was most frequently located in the lumbosacral region (35.91%). The study revealed a correlation between years of working experience and the percentage of dentists reporting pain. 71.82% of the respondents had undergone treatment for pain, 34% of whom sought the assistance of a doctor. Treatment helped improve the problem in 90.96% of cases. Conclusion. The study showed that dentists already require instruction in ergonomics during their undergraduate training and they should observe these rules during their professional careers. Regular relaxation exercise reduces or eliminates pain in the musculoskeletal system.

Cel pracy. Celem pracy była ocena występowania dolegliwości bólowych, umiejętności ergonomicznej pracy przy fotelu dentystycznym oraz częstości zachowań pro-zdrowotnych wśród lekarzy dentystów. Materiał i metody. Badanie przeprowadzono na podstawie anonimowej ankiety. Grupa składała się z 223 lekarzy dentystów (172 kobiet i 51 mężczyzn). Ankietowani odpowiadali na 3 grupy pytań, które dotyczyły danych demograficznych, metod pracy oraz odczuwanych dolegliwości bólowych i sposobów leczenia z nimi związanych. Wyniki. W przeprowadzonym badaniu potwierdzono, iż występowanie dolegliwości bólowych układu mięśniowo-szkieletowego jest zjawiskiem powszechnym. Przyczyną jest niestosowanie się do podstawowych zasad ergonomii i zła organizacja pracy. Bóle mięśniowo-szkieletowe wystąpiły u 81,86% stomatologów i u 19,13% absolwentów stomatologii - w ciągu ostatnich 12 miesięcy. Ból przewlekły dotyczył 30,09% ankietowanych. Ból najczęściej pojawiał się w odcinku krzyżowo-lędźwiowym (35,91%). W badaniu wykazano zależność pomiędzy stażem pracy a odsetkiem lekarzy, którzy zgłaszają dolegliwości bólowe. 71,82% badanych podjęło się leczenia tych dolegliwości, z czego 34% szukało pomocy u lekarza. W 90,96% przypadków podjęte zabiegi lecznicze przyniosły poprawę. Wnioski. Szkolenie w zakresie ergonomii konieczne jest już w trakcie kształcenia przeddyplomowego, a jej zasady winny być przestrzegane w ciągu pracy zawodowej lekarza dentysty. Regularne wykonywanie ćwiczeń relaksacyjno-uspokajających zmniejszy lub wyeliminuje dolegliwości bólowe układu mięśniowo-szkieletowego.
