A former university professor and an ex-member of the committee that prepares the national dental examinations admitted Monday to being involved in the leaking of exam questions in violation of the Dental Practitioners Law.

Testifying at their first hearing before the Tokyo District Court were former Ohu University professor Kenji Kusunoki, 54, and former committee member and Health Sciences University of Hokkaido professor Itsuo Ueda, 59.

Ueda admitted leaking information regarding questions in the area of oral hygiene for last March's exam to Kusunoki, who was his junior at Osaka Dental University. The exam must be passed to obtain a dentistry license.
