I am pleased to introduce "Diagnostic aids in potentially malignant disorders and malignancies" to the student community. Early detection of potentially malignant and malignant oral lesions can reduce the mortality and increase the survival rate. A concise presentation of chair side diagnostic aids to molecular methods will be of immense help to the students pursuing graduate, postgraduate studies and also for routine stomatology practice. I am sure it will benefit all the researchers as well and the editor deserves a hearty congratulation for all the effort that went in creating this textbook.
