Dentists belong to a professional group potentially exposed to harmful biological factors which most often are infectious microorganisms, less frequently - allergenic or toxic microorganisms. The fundamental routes of spreading harmful microorganisms in a dental surgery are: blood-borne, saliva-droplet, direct contact with a patient and with infected equipment, and water-droplet infections. In this paper, the current status of knowledge on microbiological hazards in a dentist's work is presented. Groups of microorganisms, such as prions, viruses, bacteria, fungi and protozoa, to which a dentist is, or may be exposed, are discussed. Epidemiological assessment of microbiological hazards in a dentist's work was performed and the basic principles of prevention formulated. Special attention was given to microflora in dental unit waterlines, and the biofilm persisting in them, as a source of occupational hazards specific for a dentist's workplace.

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.
