OBJECTIVE: This study aimed to see whether clinical healing after amalgam removal corresponds to histologic healing, i.e., a complete disappearance of any histologic sign of lichenoid lesion.
STUDY DESIGN: The study evaluated 64 patients with lichenoid lesions and at least one amalgam filling.
RESULTS: After amalgam removal, complete clinical healing was obtained in 14 patients (22%) and was significantly related to lesion topography (χ(2) 4.7; P < .05) and positive patch test (χ(2) 6.3; P < .01). Complete histologic healing was obtained in only 7 cases (50% of clinically healed patients), and was significantly related to the combination of positive patch test and strict contact with amalgams (Fisher's exact test P < .01).
CONCLUSIONS: Contact with amalgams and positive patch testing are good but not absolute indicators of the beneficial effect of amalgam replacement. In addition, complete clinical healing does not necessarily mean a disappearance of the histologic characteristics of OLL/OLP lesions.
