Caries diagnosis using light fluorescence devices: VistaProof and DIAGNOdent

Abstract

The modern concept of minimally invasive dentistry encompasses early detection of incipient carious lesions and their treatment. Due to the low sensitivity of visual inspection and radiography in the detection of occlusal hidden carious lesions under a macroscopically sound surface, several devices have been developed to increase detection accuracy. DIAGNOdent is one of the tools used for that purpose and VistaProof is a new device recently introduced into the market. They both use light fluorescence to detect incipient carious lesions. DIAGNOdent is based on the fact that carious lesions show higher level of fluorescence than sound tissues when excited by light at specific wavelength. Vistaproof is based on the same principle, but it uses a different wavelength of excitation than DIAGNOdent and a video camera for the detection of fluorescence. The aim of this article was to compare these two devices and present their clinical use.

An evaluation of a school‐based dental sealant programme

“…Under the state dental practice regulations, standing orders from a supervising dentist are required for authorization of dental sealant placement in a community setting by dental hygienists without an examination by a dentist. There was no dentist at the school site to review the radiographs for interproximal caries or provide an examination; therefore, if a child participant had suspected active lesions, the areas were verified with the DIAGNodent© (a clinically accepted measure in the United States for caries detection) and referred to a dentist for further evaluation and treatment . Teledentistry is one option for dentists to review radiographs and diagnose dental diseases from their dental offices without being physically present at the school.…”

Diagnostic Drama. Use of ICDAS II and Fluorescence-Based Intraoral Camera in Early Occlusal Caries Detection: A Clinical Study

“…Their results showed that the use of the fluorescence-based camera is the most accurate evaluation method for assessing the condition of the dental surface before the establishment of a treatment plan, followed by ICDAS-II and other methods of evaluation [7]. In addition, in the case of uncertainty for the need for treatment, VistaCam remains a great help in monitoring the development of carious lesions in pits and fissures, even over a longer period of time [14][15][16].…”

Discrimination of Dental Caries Using Colorimetric Characteristics of Fluorescence Spectrum

“…The camera uses 405-nm light, and fluorescence images with a resolution of 720 × 576 are captured and saved. The red and green components of the fluorescence images are quantified, and the results are finally converted to values ranging from 0 to 3, corresponding to the lesion's severity [Betrisey et al, 2014]. The reliability of the fluorescence camera for detecting caries lesions in occlusal and smooth surfaces of primary teeth has been investigated [De Benedetto et al, 2011].…”
