BACKGROUND: To correlate fluorescence-based camera (FC), visual inspection (ICDAS-II) and radiographic examination X-rays bitewings (BW) to the extent of caries after excavation.
METHODS: The occlusal sites of 20 permanent first and second molars in 14 young adolescents (12±2 years old) were examined at 1^st Observation Unit of Department of Oral and Maxillofacial Sciences, “Sapienza” University of Rome. All the enrolled patients were asked to provide with X-rays bitewing of the studied teeth. The assessment of ICDAS-II and FC was performed by a trained operator. Then a second blind operator removed the carious lesion and evaluated the cavity extent (depth, width, length) after caries removal with a calibrated probe. To correlate FC measurements with bitewing sensitivity, 10 dentists evaluated the presence/absence of caries on the X-rays.
RESULTS: All the occlusal sites assessed by fluorescence camera, ranged from 1.7 to 2, indicating in all cases deep enamel lesions with possible extent to dentine with a mean of 1.7±0. In accordance, visual inspection by ICDAS-II showed scores of 3 and 4. By contrast, the radiographic documentation, i.e. bitewing X-rays, was evaluated in only 6 cases as presence of caries. The extent of the cavities was determined by three consecutive measurements: depth, width and length, with a mean of 3.5+1.73, 2.8+1.07 and 3.2+1.64 mm respectively. These results confirmed the agreement between FC and ICDAS-II for diagnosis of cavities with extent to enamel and dentine, while showed the low sensitivity of bitewings X-rays, in accordance with the existing evidence in Literature. Moreover, the results of this study for the first time provide information about the cavity extent after caries removal for the occlusal sites with ICDAS-II 3 and 4 scores and FC≥1.7.
CONCLUSIONS: X-rays evaluation showed diagnostic accuracy in 6% of the sample. VistaCam measurement of 1.7 was correlated to a cavity with 3.5, 2.8 and 3.2 mm of depth, width and length.
