Background

Dental materials are widely used on a majority of people in developed countries. Adverse reactions (side effects, adverse events) do occur. The side effects range from objective reactions based on observable phenomena, to more unspecific, general reactions which may or may not be associated with dental materials. Reactions are also seen in dental personnel handling the materials. Such reactions may be troublesome for the personnel and may indicate types of reactions in patients.
Participation by dental clinicians in spontaneous reporting systems may reveal reactions that are not easily identified during pre-clinical (pre-marketing) evaluation. Several reporting systems of this kind are in action concerning drugs. With dental materials the establishment of concordance between the material and the reaction is complicated by the fact that each material may contain several components, and the composition is sometimes difficult to obtain. Such systems are still valuable tools in the identification of adverse reactions associated with dental materials.
Dental materials are classified as medical devices, according to the European 93/42/EEC Medical Devices Directive. E.g. filling materials are classified as Surgically Invasive Devices, class IIa.

The Norwegian Registry

The Norwegian Dental Biomaterials Adverse Reaction Unit was initiated by the Norwegian Board of Health in 1992 and began its activities in 1993. It is funded by the Ministry of Health and Social Affairs. The activities are at present organized in a academically and financially autonomous unit (section) closely linked to the University of Bergen.
In addition to research activities, the main purposes are to:
(1) Implement a national adverse reaction registry based on reports from health professionals.
(2) Offer clinical services to selected (referred) patients with complaints and disorders associated with dental biomaterials.
(3) Supply information to health professionals and to the public about issues concerning adverse reactions to dental biomaterials.

The Swedish Registry

Following a commission by the Swedish Government, and in accordance with the consequent parliamentary decision, The Swedish National Board of Health and Welfare implemented a national register on side-effects of dental materials in 1996. The Board decided to make an external assignment and a formal co-operative agreement was established between the Board of Health and Welfare and the Faculty of Odontology, Umeå University, for the creation of a national register of side-effects relating to dental materials. The intention was to elucidate the nature and the occurrence of side-effects that could be connected with dental materials. Information arising out of the work was to be distributed to the health and medical services, including dental care services, and to other interested parties.
In 2002 the specialized reporting procedure described above was replaced by the more general procedures based on the EU-regulations. The reporting is made mandatory in cases of (potentially) serious events. Reports are now handled by the Swedish Medical Products Agency ( Läkemedelsverket).

The UK Registry

The UK Adverse Reaction Reporting Project (ARRP) was set up in 1999 to develop the evidence base for adverse reactions to dental materials in the UK and was funded by the NHS National R&D Programme of Primary Dental Care It regularly sends out a reporting form, known as the green form to differentiate it from the yellow form used for the reporting of drug adverse reactions to all general dental practices in the UK. The design of the form was based on examples from the Adverse Reaction Units in Bergen (Norway) and Umeå (Sweden). The results of the survey are available on its website: http://arrp.group.shef.ac.uk.
