Schwendicke F, et al. – The present study was undertaken to evaluate the quality of German dentists’ websites on periodontitis, hypothesizing that it was significantly correlated with a number of practice–specific parameters. Findings revealed that most German dentists’ websites on periodontitis were not fully reliable and relevant information was not or insufficiently considered. Therefore, there was a great need to improve the information quality from such websites at least with regards to periodontitis.
