Michael Lennon, professor at Sheffield Dental School, was honoured for his pioneering work on the dental health of children at last month's meeting of the International Association of Dental Research in Toronto.

In 1993, when he was head of dental services at Liverpool University, Professor Lennon established the first UK public health programme of fluoridation of school milk in St Helen's, Merseyside. The programme has since been expanded to cover 15 PCTs and 42,000 children aged 3-11.

Professor Lennon, now chairman of the Fluoridation Society and programme manager for the dental outreach programme at Sheffield University, is pictured left with Deborah Greenspan, Professor of Oral Medicine at San Francisco's School of Dentistry and President of the IADR. He received the EW Borrow award for achievements in oral health promotion and research on the oral health of children.

Other researchers honoured at this year's IADR meeting included Professor Jimmy Steele and Dr Philip Preshaw (above), both of Newcastle Dental School, who received distinguished scientist awards. Professor Steele's award was in recognition of his work in geriatric oral health and Dr Preshaw received the young investigator prize for his work in periodontal research.
