Application of Information Technologies and Quantitative Light-Induced Fluorescence for the Assessment of Early Caries Treatment Outcomes

摘要

Information technologies (IT) and Quantitative light-induced fluorescence (QLF) are advanced technologies for dental caries detection, quantification and monitoring. Application of IT and QLF technologies to assess and monitor early dental caries stages are described in this article. In the prospective study 110 initial caries lesions in permanent teeth of 10-16-year-old children were monitored during 12 months period after the treatment. Qraycam device based on QLF technology and Q-Ray software v.1.24 (AIOBIO, South Korea) was used to assess and quantify caries lesions before and in 3, 6, 9 and 12 months after the treatment. Two treatment methods were randomly applied: caries infiltration (the first group) and peptide amelogenin application (the second group). Differences in the treatment outcomes between the groups were assessed by Student-t-test at p-value<0.05. Before the treatment mean values of fluorescence loss (?F±.) and demineralization maximum (?Fmax±.) in carious areas were similar in both groups. Visual and tactile dental examination during 12 months period after the treatment did not reveal any clinical signs of caries progression in both groups. However, QLF technology revealed significant differences between the treatment outcomes. In 12 months after the treatment, magnitudes of ?F and ?Fmax reduction (cut-off)
