The Health and Welfare Ministry on Wednesday urged a university professor sitting on the committee that formulates National Dentistry Examination questions to refrain from attending today's committee meeting due to suspicions he had earlier leaked questions.
It was discovered Sunday and confirmed Monday that one question used in the March national exam was similar to a problem in the graduation exams held in January and February for the dentistry department at Ohu University, a private university in Koriyama, Fukushima Prefecture.
Sources close to the health ministry said the committee member in question is a professor at a different university. He has so far denied involvement in the scandal.
