Overview
This study reported patch test results from Lithuanian dermatology practice using both dental screening and metal series patch test panels, characterizing the frequency and co-sensitization patterns of metal contact sensitizers including palladium. Pd emerged as a leading sensitizer in the dental context, with strong co-sensitization rates with nickel.
Key numbers
- PdCl2 positive with dental screening series: 18.0%
- PdCl2 positive with metal series: 16.7%
- Sodium tetrachloropalladate positive: 7.0% (dental); 8.5% (metal)
- 76.9% (10/13) of Pd-positive patients were also sensitized to nickel (Ni)
- Gold and palladium sensitization analyzed separately
- Palladium identified as a leading contact sensitizer in dental practice
Methods (brief)
Retrospective or cross-sectional patch test data from Lithuanian dermatology/allergy clinic. Dental screening series and metal series applied per standard ICDRG or European baseline protocols. Frequencies calculated for each allergen and co-sensitization patterns analyzed.
Implications
This page makes the source discoverable for palladium evidence routing. Provides Lithuanian population data showing Pd as a high-frequency metal sensitizer (16.7-18% by patch test series), with 76.9% co-sensitization with nickel, contributing to the European prevalence dataset.
