The study aimed to explore the link between amalgam dental fillings and oral lichen planus (OLP).
Researchers examined 81 patients with oral lichenoid lesions, identifying two main patient groups based on reactions to amalgam.
Results showed that patients with probable amalgam-contact hypersensitivity lesions (ACHLs) saw significant improvement after replacing amalgam fillings, while those with OLP without such hypersensitivity did not experience similar benefits.
The findings suggest that specific ACHLs can be positively influenced by amalgam replacement, highlighting a distinct subgroup within the broader OLP diagnosis.
