Full title: Request for collaboration from University of Lisbon Department of Endodontics regarding a Survey of members of European Endodontic Societies accredited by the European Society of Endodontology regarding obturation trends.

Esteemed Sir/Madam,

I am writing to you to request your collaboration in a research project being conducted by the Endodontics Department of the University of Lisbon in Portugal.

We would kindly request you to invite all the registered members of your society to participate in our online survey. As part of a department project about obturation trends, we designed a survey that will help us understand what is the daily practice of Endodontists in Europe.

The survey is very brief and will only take about 3 minutes to complete. The participation in the survey is completely voluntary and all of the responses will be kept confidential. No personally identifiable information will be acquired or associated with the responses. The access to the survey is done by clicking on a link which will take the participant to the survey’s Web site.
