Mike Penning – raconteur, aesthete, Shadow Health Minister and MP for Hemel Hempstead – has uncovered yet another extraordinary example of Governmental ignorance. This came out in a written answer.
"Mike Penning: To ask the Secretary of State for Health how many NHS dentists there are per 1,000 people in Hemel Hempstead constituency. 
The number of dentists with national health service activity during the years ending 31 March 2007 and 31 March 2008 per 100,000 population is available in Table G1 of Annex 3 of the report NHS Dental Statistics for England: 2007-08. Information is available by strategic health authority and by primary care trust. This information is based on the new dental contractual arrangements introduced on 1 April 2006.
Following a recent consultation exercise, this measure is based on a revised methodology and therefore supersedes previously published workforce figures relating to the new dental contractual arrangements. It is not comparable to the information collected under the old contractual arrangements. The revised methodology counts the number of dental performers with NHS activity recorded through FP17 claim forms in each year ending 31 March.
Complicated to calculate it may be. Impossible it would not be.
