유구치 인접면 우식 병소 진단에 있어 Qraypen^TM과 시진 및 구내 치근단 방사선의 비교 = Comparison between Qraypen^TMImaging and the Conventional Methods of Visual Inspection and Periapical Radiography for Proximal Caries Detection in Primary Molars: An In Vivo Study

다국어 초록 (Multilingual Abstract)

The purpose of this study was to evaluate the efficacy of the newly-developed Qraypen^TM(All In One Bio, Korea) system for the diagnosis of early proximal caries by comparing it with the conventional methods of visual inspection and periapical radiography. This study was carried out from July 2015 to April 2016 targeting 32 children aged 7∼12 years who visited Y-Dental Clinic for school oral health examinations. Two investigators selected and examined a total of 153 primary molars that had not undergone restorative treatment. Comparisons were carried out between visual inspections, readings of posterior periapical radiography images, and readings of Qraypen^TMimages. This study revealed that the percentage of interproximal surfaces of primary molar teeth without caries incidence was 83.7% using Qraypen^TM imaging and 84.9% using visual inspection and periapical radiography. The differences between the two methods were not statistically significant. Thus, Qraypen^TM is expected to be a useful and convenient auxiliary diagnostic device that can facilitate the detection of hidden proximal caries in primary molars.
