§ Mr. WigleyTo ask the Secretary of State for Wales if he will publish figures to indicate the change in incidence of periodontal diseases in the Welsh population between 1990 and 1993.
§ Mr. Gwilym JonesThe information requested is not available centrally. Information on the incidence of periodontal disease is collected in a United Kingdom survey carried out every 10 years. The last report "Adult Dental Health" covered the years up to 1988 and is held in the Library of the House.
