Changes in dentist and dental hygienist numbers in the European Union and Economic Area

Aim: To investigate the extent to which changes in the numbers of dental hygienists and dentists have occurred in the Member States of the European Union and Economic Area (EU/EEA) during the last ten years and discuss the changes in relation to the possibilities of sharing tasks between the two groups. Methods: Numbers for active dentists, registered hygienists and EU/EEA member state populations in 2007 were taken from the website of the Council of European Chief Dental Officers (CECDO) (http:www.cecdo.org) and from CECDO records for the EU/EEA member states in 1998 and for the new EU member states (who joined in 2004 and 2007) in 2000. From these data, population: active dentists, population: registered dental hygienist and active dentists: registered dental hygienist ratios were calculated together with percentage changes in the number of dentists and dental hygienists by member state, between 1998 and 2007 for the old and between 2000 and 2007 for the new EU member states. Results: In 2007, there were a total of 343,922 active dentists and 30,963 registered dental hygienists in the 30 EU/EEA member states plus Switzerland. The mean population to dentist ratio was about 1,500:1 and the mean population to dental hygienist ratio (in the 25 states where dental hygienists were registered) was 13,454:1. During the study period, the population of the EU/EEA plus Switzerland increased by less that 3%, the number of dentists increased by 13% and the number dental hygienists by 42%. The overall ratio of active dentists: dental hygienists changed from 18:1 to 11:1. In six of the 30 member states plus Switzerland the population to dental hygienist ratio was between 2,000:1 and 6,000:1 and the dentist: dental hygienist ratio less than 1:3. Conclusions: Although, most member states educate dental hygienists and their numbers in the EU/EEA during the last 10 years have risen more than the dentist numbers, there are still only a handful countries where the hygienist numbers are great enough to make a significant difference to the delivery of oral health care.
