Use of a fluorescence-based camera for monitoring occlusal surfaces of primary and permanent teeth

Background Sound teeth and incipient lesions require regular monitoring to detect possible progression of caries early on. Aim To evaluate the ability of the VistaProof (VP) fluorescence-based camera for monitoring occlusal surfaces. Design A total of 419 posterior teeth (205 primary molars, 145 permanent molars, and 69 premolars) of 35 patients were examined (average age: 9.1 years). The occlusal surfaces were classified visually according to the criteria of the International Caries Detection and Assessment System (ICDAS). VP measurements were performed at baseline (t1), and the examinations were repeated after six (t2) and twelve month (t3). Correlation between methods was calculated using Spearman's rank correlation coefficient (rs). Wilcoxon test was used to monitor whether VP identified changes as well as ICDAS (α = 0.05). Results Correlations between ICDAS and VP were significantly positive (rs: 0.66–0.73, P
