Treatment planning for the problem patient: restorative, ethical, legal and psychological perspectives. Case I: Emma.

'Emma' is the first of a series of four articles that aims to look at some of the problems patients may present with when they visit their dentist. Each article starts with a brief scenario about the hypothetical patient and his/her clinical problems. As well as the clinical problem, each case also raises ethical, legal or psychological problems. All of these issues are discussed and possible management strategies and treatment options described.
