A Comparative Evaluation of DIAGNOdent and Caries Detector Dye in Detection of Residual Caries in Prepared Cavities

Abstract

Aim:The objective of this study was to determine the association between DIAGNOdent laser and caries detector dye in detection of the remaining caries in restorative cavities. Materials and methods:The sample consisted of 100 cavities prepared in patients referring to the Department of Restorative Dentistry of Mashhad Dental School. After confirming caries absence by tactile examination, the presence of any residual caries was determined by a laser fluorescence (LF) device (DIAGNOdent Pen) and then by caries detector dye. The data were analyzed through McNemar test.Results: When the cut off value was considered as 13, both DIAGNOdent Pen and caries detector dye found 54 cavities as without caries and 12 cavities as carious. There were 32 teeth diagnosed as decayed only by the dye and two cases that were diagnosed as having residual caries only by the DIAGNOdent. The McNemar test revealed a significant difference in the diagnosis of residual caries between the two methods (p < 0.05), as well as significant differences between each method and tactile examination (p < 0.05). When the cut off value was set at 25, no significant difference was found between laser fluorescence and tactile examination in residual caries detection (p > 0.05). Conclusion:Both DIAGNOdent Pen and caries detector dye can be considered as adjuncts for detecting residual caries in prepared cavities. However, the use of laser fluorescence device can provide results that are more consistent with tactile examination, while relying on caries detector dye may result in excessive removal of tooth tissue, and thus increase the risk of pulpal exposure.Clinical significance: Incomparision with caries detector dye, Residual caries detection by DIAGNOdent Pen is more consistent with tactile examination.

Effectiveness of MI Paste Plus and Remin Pro on remineralization and color improvement of postorthodontic white spot lesions

“…[ 27 ] It has been demonstrated that fluorescent-based systems are suitable for visual detection of caries lesions. [ 28 29 ] In this study, VistaCam iX was employed to capture fluorescent images. A previous study indicated that this fluorescent camera provides high reproducibility and good performance for caries detection at various stages of the disease process.…”

The effects of three remineralizing agents on regression of white spot lesions in children: A two-week, single-blind, randomized clinical trial

“…This device is small and portable and thus easily applied in the clinical situation. It has been demonstrated that fluorescent-based systems are suitable for detection of caries lesions and assessing alteration in mineral level of tooth structure (17,24-26). Jablons-ki-Momeni et al (27) exhibited that VistaCam iX provides high reproducibility and good performance for caries detection at various stages of the disease process.…”

Emerging Technologies for Dentin Caries Detection—A Systematic Review and Meta-Analysis

“…DIAGNOdent (DD) groups, utilizing the LF technology, comprised the largest number of studies included in this meta-analysis. There are two DD devices: DIAGNOdent 2095 (DD 2095) and DIAGNOdent pen 2190 (DD pen) [28,80]. DD 2095 works only on occlusal surfaces, whereas the DD pen works on both occlusal and proximal surfaces [81][82][83].…”
