Changes in health over time in patients with symptoms allegedly caused by their dental restorative materials

Abstract

Patients with complex symptoms had a more unfavorable long-term prognosis concerning persistent complaints than those with localized symptoms only. Furthermore, the results indicate that the patients might experience health improvements after removal of their dental restorative materials. The reason for this improvement, however, is unclear. Further analyses regarding other possible explanations than the 'odontological/medical' are needed.
