Fast calculating surrogate models for leg and head impact in vehicle-pedestrian collision simulations.

Objective: In previous research, a tool chain to simulate vehicle-pedestrian accidents from ordinary driving state to in-crash has been developed. This tool chain allows for injury criteria-based, vehicle-specific (geometry, stiffness, active safety systems, etc.) assessments.

[Rare case of the large-sized, unilateral incisive canal cyst].

A rare case of an extremely large, unilateral incisive canal cyst (nasopalatine duct cyst), located between the teeth #11 and #25 is presented. The upper border of the cyst extended to the nasal cavity, the posterior border was the maxillary sinus while the lower border was 5 mm above the maxillary alveolar process. The apices of the vital teeth 21, 22, 23 were in the cyst.

[Bacteriological study of air in dental offices].

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.

[Frequency of blood contamination of the dentist during conservative and prosthetic treatment].

The endangerment caused by the blood contents of spray formed in the course of oonserving and prosthetical work of dentists performed by dental drill was examined. It was found that the protective mask in case of grinding and drilling the front teeth becomes always while in case of treating the molars less frequently soiled. In the course of prosthetical work it occurs frequently that bloody spray reaches the hair of the physician.
