Unlabelled: Authors investigated the quality and quantity of the bacteria in the air of a dental surgery practical-room with 6 chairs. They measured the changes of bacterial count during the practical lessons. Equipment HYCON RCS Plus was used.
Results: Quantity of the bacteria in the air of this dental surgery was very high. The number of the staphylococci didn't meet the authors' previous expectations. Dispersity of the bacteria was not equal, the highest number was measured at the centre of the room.

Background: Bacteria in physiological environments can generate mineralizing biofilms, which are associated with diseases like periodontitis or kidney stones. Modelling complex environments presents a challenge for the study of mineralization in biofilms. Here, we developed an experimental setup which could be applied to study the fundamental principles behind biofilm mineralization on rigid substrates, using a model organism and in a tailored bioreactor that mimics a humid environment.

Background: To improve the success rate of mini-implants, some surgical guides have been developed through digital technologies to achieve three-dimensional (3D) guided mini-implants insertion. However, there is no a surgical guide which can be applied for the insertion of infrazygomatic mini-implant. In this study, we introduced a two-trajectories surgical guide and investigated the success rate of infrazygomatic mini-implants under the guidance of the template.
