LONDON U.S. private equity group Carlyle (CG.O) has appointed Rothschild ROT.UL to explore possible exit options for UK firm Integrated Dental Holdings (IDH), two sources familiar with the matter said on Wednesday, in a deal which one said could be worth between 1 billion pounds ($1.7 billion) and 1.5 billion.
IDH, Europe's largest corporate dental company, was bought by Carlyle in May 2011 for a reported 450 million pounds.
Rothschild has been appointed to look at options that could include a sale or a stock market listing, one of the sources said, cautioning that discussions were still in their early stages.
IDH has around 550 dental practices and 10 million patients across Britain, primarily as part of the UK's publicly funded National Health Service (NHS).
Carlyle declined to comment. Rothschild was not immediately available for comment.
