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.

Long-lasting symptoms aggravated by environmental factors exist within this group of patients. The results support that early and comprehensive measures for rehabilitation are essential for the patients.

The results suggest that skin symptoms reported by VDT users have a multifactorial background.
