Cawsons Essentials of Oral Pathology and Oral Medicine is a new edition of a classic textbook of oral pathology and oral medicine
Undergraduate students will never see many of the conditions discussed in this book. Despite this, on qualifi cation they are expected to not only diagnose them, but also institute appropriate referral or treatment. This, the eighth edition of Cawson’s Essentials, is therefore not only updated, but also designed to make clinical relevance immediately accessible to the learner.
We have used more colour illustrations and have introduced symbols to link the text to the diagnostic summary charts. The text has been updated with many new sections on cancer, premalignancy, osseointegration, sinusitis and disturbances of taste, as well as new diseases such as bisphosphonate-induced osteonecrosis. There is a new section on normal healing of tooth sockets, an important topic hardly covered elsewhere. Some chapters have changed relatively little, such as that on caries, but the importance of understanding the disease process is now more clearly linked to clinical practice in tables.
Self-directed learning is critical to develop understanding.New learning guides now follow each section, an attempt to help students direct their own learning from other sources, because no book can be comprehensive. References have been updated but remain largely unchanged. Often the older classic papers are those of most use to xv undergraduates and the retention of these older papers is deliberate.
Our thanks are due to Clive Hewat, Alison Taylor, KerrieAnne Jarvis, Erik Bigland, Mike Parkinson and all the team at Elsevier for maintaining the excellent production standards and rescuing many of the older, now almost irreplaceable, photomicrographs.
This edition of Cawson’s Essentials is, sadly, the last to which Professor Cawson will contribute. He died shortly after the manuscript was completed. A dedicated teacher, he understood how students were often baffl ed by the complexity of our subjects. He was a master of succinct text and ruthless in editing out ideas without an ‘evidence base’, long before the expression had been invented. Cawson’s Essentials has been published continuously since 1962 and it was the fi rst textbook to integrate oral medicine, pathology and surgery in a practical, studentorientated fashion. The many students who have relied on it over the last nearly half-century give testimony to his breadth of knowledge, intellectual authority and the clarity of his writing.
