“…The novelty of this system lies in the bespoke software (QA2 version 1.24, Inspektor Research Systems BV, Amsterdam, the Netherlands) that allows measurement of variation of the fluorescence on enamel surfaces reflecting mineral density changes. 52 However, literature on the QLF technologies can be confusing as authors usually name the system solely as QLF, despite six different devices having been developed for research or clinical purposes.…”

“…Accumulated evidence and advanced prevention techniques of dental caries have contributed to the reduction in the prevalence of dental caries [ 1 , 2 , 3 , 4 , 5 ]; however, in developing countries, the prevalence of dental caries in children remains high and is one of the major public health concerns [ 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ]. In these countries, dental treatment is still insufficient [ 15 ].…”

In developing countries, the prevalence of dental caries in children remains high, which means that implementing a simple and convenient classification is critical. The classification needs to be evidence-based and needs to reflect tooth-level information. In this study, the prevalence of dental caries in the primary dentition of 352 Myanmar school children at the ages of 5, 6, and 7 was analyzed at the tooth level to clarify the underlying data structure of the patterns of dental caries in the population. Ninety-three percent of subjects had caries in primary dentition and the mean number of decayed teeth in primary dentition was 7.54 ± 4.82. Based on the item response theory analysis, mixed-effect modeling, and Bayesian network analysis, we proposed the following classification: Group 1: No dental caries; Group 2: Dental caries in molar teeth or dental caries in maxillary anterior teeth; Group 3: Dental caries in both molar and maxillary anterior teeth; Group 4: Dental carries in mandibular anterior teeth. Dental caries (dmft) in the groups was different between groups. The results of characteristics of tooth-level information and classification presented in this study may be a useful instrument for the analysis of the data of dental caries prevalence in primary dentition.

“…Previous studies have reported that porphyrin derivatives are mainly used as uorescent dyes for caries lesion assessment with laser uorescence (LF) 36,37,38,39,40 . However, the porphyrin derivatives are not suitable as a uorescent dye for DEQLF, since they already exist in natural caries lesions as bacterial metabolites 20,41,42,43,44 .…”

We aimed to determine whether dye-ehanced quantitative light-induced fluorescence (DEQLF), wherein the porous structure of carious lesions is filled in with a fluorescent dye, can be used to quantitatively and intuitively distinguish between active and inactive carious lesions. To simulate active and inactive caries, lesions were artificially formed on 126 bovine specimens. They were demineralized with 1% carbopol solution for 3 (A3), 5 (A5), and 10 days (A10). Half the specimens in each group were remineralized with 2% NaF (I3, I5, and I10). The specimens were dehydrated for 10 s and dyed with 100-µM sodium fluorescein for 10 s. Images were captured with a QLF-digital 2+ Biluminator. Fluorescence intensity of the lesions (ΔG) between the groups and absolute changes in ΔG (|ΔΔG|) between dehydration and dye penetration were compared using the independent t-test. ΔG in A3, A5, and A10 were higher than those in I3, I5, and I10 (P<0.001). In |ΔΔG| comparisons, dye penetration was 3.1-3.7 times higher than dehydration in the active group (P<0.001), and was 1.7-2.2 times lower than dehydration in I3 and I5 (P<0.05), with no significant difference in I10. DEQLF may be used to clinically evaluate early caries activity, and longitudnally monitor changes in lesion activity.
