With a long and distinguished 70 -years history the European Organisation of Caries Research (ORCA) successfully promotes oral health through scientific research in the field of Cariology.

 In 1953, ORCA was founded as an international organisation based in Europe and since then it has been brought together dental professionals from all around the world.

Dr Heuser proposed that the Organization should have ‘the aim of promoting research on fluorine and dental caries prevention’. This aim was approved and amended by the General Assemblies held in Geneva (Switzerland) 1955 and in Malmö (Sweden) 1957.

Almost fifty years after the first aims had been put down, the actual aims of ORCA have been only slightly modified:

1. To promote research into dental caries and related matters.
2. To evaluate the findings of research to encourage their practical application and to prevent their abuse.
3. To establish close contacts between all individuals and organizations with similar aims, without distinction as to nationality

In the eighties, ORCA grew constantly and attracted more and more the interest of American scientists, mainly for three reasons:

1. The work of ORCA was more and more appreciated by American scientists, resulting in the above-mentioned activities and joint meetings.
2. Several ORCA members left Europe, for instance Bill Bowen (to USA), Tony Hargreaves, George Bowden (to Canada). Harald Linke had even much earlier emigrated to the USA
3. Some American scientists had family roots in Europe. Ernie Newbrun’s parents originated from Vienna. Jim Carlos was married to a German. He and his wife used ORCA meetings for family reunions. He even succeeded in getting the ORCA Congress one year to the USA: to Annapolis, the first capitol. Afterwards he was a long-standing member of the Board.
