Sir, I have read Dr Hussain's letter in the 25 August issue of the BDJ (213: 147) and have great sympathy in his battles to deal with public comments on the NHS Choices website that is attempting to turn NHS dentistry into a health version of Trip Advisor.

I have been contacted by many colleagues equally affected by such things as anonymous potentially libellous comments with poor moderation of the site and reluctance to remove comments that are completely without foundation.

I am aware of a group of dentists who have a strong legal opinion that may challenge the duty of care of the site that has allowed commercially damaging comments attached to many practices.

I'm keen to hear from anyone who may have similar stories to Dr Hussain and would value their assistance if they could contact me at ecrouch9@btinternet.com.
