It is said that periodontal disease may well be the commonest disease on the planet, it is certainly seen by all dental general practitioners and is one of the major components of the undergraduate clinical dentistry curriculum. This book provides dental students with high quality pictures giving them practice in the visual recognition of periodontal conditions, and with a concise descriptive text in the proven "Colour Guide" format. For consistency and ease of use the text describes each condition under the following headings: aetiology; incidence; clinical features; special investigations; and, treatment. As ever with the "Colour Guide" titles, text and illustrations are on facing pages, making the book both ideal for learning and useful for self-testing.
