The role of direct visual fluorescent examination (VELscope) in routine screening for potentially malignant oral mucosal lesions

ObjectiveDirect visual fluorescent examination (DVFE) is a proposed adjunct to conventional oral examination (COE). We evaluate the benefit of DVFE in screening for potentially malignant mucosal lesions in a general population of patients presenting for dental care.Study DesignA total of 130 patients were evaluated by COE followed by DVFE. Areas clinically suspicious by COE or with positive DVFE (visual fluorescence loss [VFL]) underwent surgical biopsy. Association between COE and DVFE was assessed and compared with histopathology.ResultsA total of 42 subjects had one or more areas of VFL, yet histologic evidence of premalignancy/malignancy was only identified in a single individual. Further, one lesion negative by DVFE exhibited epithelial dysplasia. DVFE was statistically different from scalpel biopsy (P = .0001). No difference was found between COE and scalpel biopsy (P = 1.0).ConclusionsResults suggest that COE is more valid than DVFE at discriminating benign mucosal alterations from premalignancy and do not support use of DVFE as an oral cancer screening adjunct.
