Oral Diseases: Grading and Staging focuses on the different types of grading and staging system of soft tissue diseases affecting the head and neck , with emphasis on premalignant and malignant lesions. This work has been prepared keeping post graduate students in mind as it provides easy access to the concisely collected information. It further incorporates the ICD disease classification and hence is a timesaver for the post graduate. Although primarily for post graduate students it is an equally helpful book for graduates, academicians and clinicians. We look forward to suggestions that may help in improving the book in future.
