“…Based on this finding, it has been suggested that the reflectivity from the lesion area can be directly determined and then used as a measure of the lesion severity 19,20) . It has also been shown that shallow lesions exhibit a loss of penetration depth in OCT images and this is correlated with the mineral loss that can be detected with microradiography 21) .…”

The purpose of this study was to determine the effect of PRG filler extraction solution on the demineralization of enamel using optical coherence tomography (OCT). Bovine enamel was treated with lactic acid buffer solution and then placed in artificial saliva (De group). In the second group, specimens were stored in PRG filler extraction solution followed by immersion in lactic acid buffer solution (PRG group). In the control group, specimens were simply stored in artificial saliva. From the OCT image, the peak intensity (dB) and width at (1/e 2 ) were obtained, and the integrated value was calculated. The data were analyzed using Tukey-Kramer tests (α=0.05). There was a slight but significant increase in the integrated value observed for the control group, and a slight but significant decrease in the value observed for the De group. For the PRG group, integrated values were doubled after seven days from the start of the experiment.

“…In the case of sound dentin, the perpendicular axis signal was relatively weaker because of light scattering and depolarization, whereas in demineralized dentin, the perpendicular axis signal was strong. Therefore, a strongly increased signal in the A-scan serves to represent the severity of demineralization 27) . In the PRG group, a higher peak signal intensity and broader width at 1/e 2 were observed, because of the occlusion of dentinal tubules by the varnish material.…”

Evaluation of the effects of fluoride-releasing varnish on dentin demineralization using optical coherence tomography

et al. 2014

Effects of a fluoride-releasing varnish containing surface reaction-type prereacted glass ionomer (S-PRG) filler on dentin demineralization were examined using optical coherence tomography. Bovine incisors that were sliced and treated with undersaturated 0.1 M lactic acid buffer solution (DE group). A thin film of varnish-containing S-PRG filler was applied before demineralization (PRG group). Control was maintained in artificial saliva. Using optical coherence tomography of selected locations on the dentin surface, peak intensity (dB) and width (μm) at 1/e 2 were obtained and integrated values calculated. Although alterations in integrated values were different in each group, there was a slight but not significant increase in those for the control group and a slight but significant increase for the De group. For the PRG group, integrated values were doubled seven days after experiment initiation, followed by a significant increase. Fluoride-releasing varnish containing S-PRG fillers prevented dentin demineralization as detected by optical coherence tomography.

Previously, we indicated that a silver staining method generally used in protein gel electrophoresis could be applied to stain undecalcified tooth sections for observation of fine structures in dentin and cementum. In this study, we attempted to observe the carious lesions of enamel and dentin with the silver staining method. When undecalcified ground sections of teeth were stained with the staining method, carious lesions on dentin showed layer staining pattern, and the staining patterns seemed to be corresponding to the histological zone of the carious lesions. Furthermore, it was clear that discoloration of tooth sections stained by silver was promoted by UV light exposure, as a result, the enamel carious lesions could be observed. Our results suggested an application possibility of the silver staining to detect the carious lesions in both dentin and enamel.
