Abstract

This study was aimed to define the predicting factor account for the Korean Dental Hygienist Licensing Examination (KDHLE) by analyzing theacademic grade score and the KDHLE score. The subjects included 185 graduates (2007, 2009, 2011∼2014 graduates). The ratio of successfulapplicants of the subjects was 99.2%. The academic grade scores were calculated to grade point average, the KDHLE was scoring marks out of300 (200 of written examination score and 100 of performance evaluation score) for correlation and regression analysis. The graduation grades andcomprehensive examination scores correlated significantly with the KDHLE written examination scores (correlation coefficient=0.612), and KDHLEtotal score (correlation coefficient＝0.258). First∼third grade score and comprehensive examination scores correlated significantly with KDHLEtotal scores (p＜0.05). Especially, there are the highest correlated between second comprehensive examination scores and KDHLE total scores(correlation coefficient＝0.455), the last score in time sequence is the important factors account for the KDHLE total score. But there is nocorrelation between academic grade score and KDHLE performance evaluation scores, therefore it is necessary to study for determine the reason. The results of multiple linear regression analysis, second grade score and the average score of comprehensive examination were the mainpredicting factors account for the KDHLE total score, the explanatory power was 31.6%. Our results show that KDHLE total and written examinationscores are predicted by the academic grade score reliably, but not the KDHLE performance evaluation scores. Further studies are needed todetermine relationship between dental hygiene education and KDHLE.
