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.

Introduction: Asymptomatic inflammatory foci resulting from chronic dental infections or the presence of foreign bodies, e.g., in the sinuses, leading to serious local and systemic complications. These conditions, despite the absence of symptoms, are a source of bacterial, toxic, allergic, and neurogenic effects. Despite the developed radiological diagnostics in the form of pantomographic images and cone beam computed tomography (CBCT), thermal imaging is increasingly mentioned as an auxiliary tool in detecting and treating inflammatory foci of the craniofacial region. It is due that thermal imaging can bring indirectly metabolic information about studied tissues and thus allow the detection of early inflammatory lesions yet not invisible on X-ray diagnostics. The purpose of the study was to apply and validate a protocol for identifying asymptomatic inflammatory foci in the maxillofacial area using thermal imaging. Material and methods: Patients referred to the institute were examined for the presence of inflammatory foci. Analysis of radiographs revealed asymptomatic foci in the maxillary sinus, which were associated with the presence of a displaced foreign body. Thermographic examinations were performed using a FLIR T540 thermal imaging camera. Results: The obtained results showed a significant temperature difference between the suspected and opposite sinus. It was also confirmed that after the foreign body was removed from the sinus the temperature showed a dynamic decrease in time. Conclusions: According to the study, thermography has the potential to become an essential diagnostic tool for inflammation of odontogenic origin. It offers non-invasiveness, safety, real-time imaging, painless and completely safe.

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.

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.

Introduction. Glass-ionomers have the ability to chemically bond to enamel and dentin, and are characterized by longterm fluoride release and absorption of fluoride from surrounding sources. Objective. The aim of the presented long-term clinical trial was to evaluate and compare the three-year clinical performance of the experimental glass-ionomer cement ‘SJZ/W’ with the bi-functional fluid placed in carious and non-carious cavities. Material and methods. Seventy restorations were made in adult patients of both genders. Clinical evaluation was performed at baseline and yearly intervals after placement using Ryge’s scale, considering the surface structure, anatomical form of the restoration and marginal integrity. Results. Immediately after placement, 70 restorations were assessed, 65 of which were subject to clinical evaluation after a year, 63 subject to clinical evaluation after 2 years, and 3-year evaluation was made for 55 restorations. The material showed minor changes in evaluated parameters and no differences were detected between their performance at baseline, and after three years only in anatomical shape. No post-operative sensitivity was recorded. Conclusion. The examined glass-ionomer ‘SJZ/W’ provided an acceptable clinical performance over a three-year period.

Governments of different countries and healthcare organisations working in various areas face enormous challenges when trying to combat the COVID-19 pandemic and protect employees, their families and communities. Workplaces can be high-risk environments in terms of the virus outbreak and transmission. This paper aims to disclose the ways for workplace safety improvement in dentistry in the context of COVID-19. The authors present the theoretical model of workplace safety improvement with regard to COVID-19 infection prevention and control measures. The expectations, fears and tasks of dental employees at their workplace in the context of the COVID-19 pandemic were investigated based on the systematic literature review and the qualitative empirical study conducted in Lithuania. The study disclosed that unmet employee expectations could lead to different kinds of fear; the most common sources of anxiety are linked to a higher risk of getting infected, a lack or misuse of protection measures and inadequately performed work. Occupational risks are closely related to the components of a workplace system. Therefore, it is important to apply a holistic approach to improve workplace safety, enhance work performance and minimise the negative effects on an employee, an organisation, a patient and a society.

Zbadano wpływ czasu prowadzenia fotopolimeryzacji na wybrane właściwości, w tym efektywność fotopolimeryzacji, materiału Filtek Ultimate. Badania uwzględniały ocenę twardości, mikrotwardości, średnicowej wytrzymałości na rozciąganie oraz oszacowanie stopnia konwersji w masie, jak i w warstwie wierzchniej. Zmienny czas naświetlania kompozytu nie wpłynął w znaczący sposób na właściwości materiału. Każdorazowo uzyskano zadowalający stopień konwersji (powyżej 65%). Najlepszymi właściwościami, również z punktu widzenia głębokości sieciowania, charakteryzował się kompozyt naświetlany przez 120 s.

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 concentration and composition of fungal flora in dental unit waterlines (DUWL) were evaluated. For this purpose, water samples from unit reservoirs and high-speed handpieces, and biofilm samples from the waterline walls from units were collected. Subsequently, analogous samples from DUWL were taken before and after disinfection using agent containing hydrogen peroxide. In the examined samples, the yeast-like fungi Candida albicans, Candida curvata and Geotrichum candidum were found. The following species of mould were also identified: Aspergillus amstelodami, Aspergillus fumigatus, Aspergillus glaucus group, Aspergillus (=Eurotium herbariorum) repens, Citromyces spp., Penicillium (glabrum) frequentans, Penicillium pusillum, Penicillium turolense and Sclerotium sclerotiorum (Sclerotinia sclerotiorum) . Before disinfection, Candida curvata and Candida albicans constituted the greatest proportion of the total fungi in the reservoirs water; in the water of handpieces - Candida albicans and Aspergillus glaucus group; and in the biofilm samples - Aspergillus glaucus group and Candida albicans. After disinfection, in all 3 kinds of samples, Candida albicans prevailed, constituting from 31.2-85.7% of the total fungi. The application of agent containing hydrogen peroxide caused a significant decrease both in the number of total fungi and individual fungal species, which confirms the product effectiveness in fungal decontamination of DUWL.
