The title states that this paper is a critical review. However, two key questions are not explored namely, 1) what is the prevalence of oral signs in those who have eating disorders (ED), and 2) how long has the ED to be experienced before these are manifest? Nevertheless, this paper reinforces the dental findings of ED. 'Reduction in intake of vitamins and other nutrients, as well as other metabolic alterations and iron deficiency anaemia' may result in generalised mucosal atrophy and glossodynia. It is also stated that sialadenosis, particularly of the parotid glands, is a frequent occurrence in ED and may be the presenting sign. There are ongoing studies examining 'the use of bisphosphonates in prevention and management of generalized bone loss.' The dentist should be vigilant that those with anorexia nervosa may be taking bisphosphonates with their associated dental implications.
