The purpose of experimental practice at university hospital is to make students realize the purpose consciousness as a dental student and the real image of a dentist. It has been carryied out a far early stage of 1st-year students. This time, we reported the results in 2005 about the problem which was obtained by questionnaire from the KJ method and 2D arrangement method in 2004. Method: we carried out a questionnaire on 78 agreeing students, and it's categories were 22 items selected by importance and degree of urgency and 17 by countermeasure correspond from the KJ method and 2D arrangement method in 2005. Analysis procedure used factor analysis and Logistic recursion analysis. Results of this research show, that: 1. About importance ; "Correspondence of an inappropriate instructor" and "Appropriate contents of guidance" etc were indicated by unsatisfied students. On the other hand, satisfied students indicated "Correspondence of inappropriate instructor" and "Bad manners of students" and so on. 2. Degree of urgency ; "Inappropriate correspondence of instructor" and "Indifference of students due to information deficiency" by unsatisfied students, and "Inappropriate instructor correspondence but he let students free" and "Bad manner of students" by satisfied students. 3. Countermeasure corresponds ; "Technical knowledge study by pre-discussion" and "Reconsideration of time zone and discussion" by unsatisfied students, and "Appropriate guidance and practice frequency" and "Extramural study wishing and explanation of practice outline" by satisfied students. 4. Only in importance, "Freedom of a re-study tour" was statistically significant correlation by Logistic recursion analysis (p<0.05). There was no high influence in "Degree of urgency" and "Countermeasure corresponds". According to them, we found such problems as "Ill-preparation of an implementation manual on enforcement side" and "Inappropriate correspondences of instructor" which should be solved immediately. Additionally, there is a differance in idea between unsatisfied and satisfied students about the 2nd study tour. From the above, we reconfirmed the necessity and importance of early exposure study.
