Dear Colleagues,

To give as many dentists as possible the opportunity to answer the survey, we have decided to push back the deadline to June 10, 2015.

We would like to thank all of you who have already filled out this questionnaire: Since your participation is confidential, you have received this letter even if you have already participated. If you have not already answered the survey, we ask  once again that you please do so, as it is essential that each and every one of you answers it as soon as possible. (read more)
