Oral mucosal screening as an integral part of routine dental care

The principal aim of this study was to assess the feasibility of conducting a systematic examination of the oral mucosa, as an integral part of the routine dental check-up and in conditions comparable with those in NHS dental practice. A total of 1949 individuals, who were already registered as patients with an industrial dental clinic, were invited to attend for an oral screen as part of their dental examination. Of these, 1947 patients agreed to participate and were also asked to complete a 'habits' questionnaire relating to their tobacco and alcohol use. A systematic examination of the oral mucosa was undertaken as part of the routine dental inspection and mucosal lesions were recorded as either a positive or negative screening result. Lesions included as a positive result were those which may be associated with early cancer or precancer. Four patients (0.2%) were considered to have a positive screening result and these were referred for specialist evaluation. Of these, two had tobacco-related leukoplakia, one had oral lichen planus and the other had an early squamous cell carcinoma. This study has confirmed that a systematic and thorough examination of the oral mucosa can realistically be carried out as part of the routine dental inspection in NHS dental practice.
