Article Synopsis
- - The study aimed to see how different surface treatments of zirconia affect biofilm formation compared to polished titanium in a lab setting and real-life conditions.
- - Various zirconia surfaces were tested (polished, heat-treated, machined, and sandblasted), and findings showed that polished surfaces led to significantly lower biofilm growth in vitro than titanium and some treated zirconia samples.
- - Results indicated that for in vitro biofilms, surface treatments influenced growth, while in situ, the roughness of the surfaces was more critical, suggesting polishing zirconia helps minimize biofilm formation.
In the surroundings of five industrial plants, noise immissions (industrial noise and non-industrial noise) were measured and residents asked by a questionnaire about the effects (annoyance and reactions) caused by industrial noise. The questionnaires of a total of 1498 (58%) residents could be analyzed. The Leq for the industrial noise ranges from 37 to 68 dB(A) in the daytime and from 37 to 59 dB(A) in the nighttime.

The results revealed that noise immissions exceed the "alarm-value" of 70 dB(A) and that pollution of the air is situated in the range of limit values.
