title: Premalignant lesions of the oral mucosa.
abstract: The term premalignant lesion is defined and an explanation of the logical use of the term leukoplakia is given. The more common premalignant lesions of the mouth are described. Known and suspected aetiological factors in the development of oral carcinoma are discussed. It is emphasised that oral squamous cell carcinoma is, very largely a preventable disease. Signs of premalignancy in the mucosa can usually be detected clinically and remedial action at an early stage is generally effective in eliminating the lesions and avoiding their recurrence.
