MELISA testing: improving outcomes in dentistry through specialised testing
Do your patients suffer from?
- Oral diseases: Lichen planus, stomatitis, glossodynia, burning mouth, cheilitis
- Successive implant failure with no infection ie “cluster patients”
- Skin rashes, chronic fatigue, fibromyalgia and worsening autoimmune disease
If so, you may consider MELISA testing as part of your diagnostic protocol.
Metal allergy is an overlooked area in dentistry and may be responsible for diverse symptoms.
MELISA testing is the best method for diagnosing metal-induced delayed hypersensitivity (1) (2) (3).
A blood sample sent to our laboratory can be checked for allergy to all metals used in dentistry, as well as to methacrylates.
Titanium allergy is uncommon, but with implant failure rate estimates varying between 7.6% and 26% (4) (5)
metal allergy may be investigated with MELISA.
MELISA may also be used to pre-test for compatible materials for patients reporting prior dermal reactions to metals.
- 76% of chronic fatigue patients experienced health improvement after removing dental
restorations containing allergenic metals, identified by MELISA testing. (6)
- 71% of patients with autoimmune diseases and mercury allergy improved after
having their amalgam fillings removed. (7)
- 50% of fibromyalgia patients showed that after restricting exposure to metals they were
allergic to, they no longer fulfilled the criteria for fibromyalgia. 20% had reduced trigger
points and all reported improvement in symptoms. (8)
- 37% of symptomatic patients (muscle and joint pain, chronic fatigue, dermatitis and
acne-like inflammation) were found to be allergic to their titanium dental work/implants
through MELISA testing (all negative in patch testing). Following removal of the implants,
all 54 patients showed remarkable clinical improvement. (9)
Based on more than 20 years’ research, MELISA has identified symptoms and indicators for
those likely to be metal hypersensitive. Studies show that if metal allergy is found, both
outcome and symptoms will improve if exposure to relevant metals is reduced. Both a
comprehensive questionnaire and a brief online version are available. A complete evaluation
with a list of metal exposure can be provided if the full questionnaire is completed.
