Woman, 54, develops eczema on her hands and feet after an allergic reaction to the nickel in her dentures
- Unnamed woman had previously responded to metal jewelry
- Metal allergy expert made the connection after a dermatologist missed it
- Symptoms disappeared when nickel implants were replaced by titanium implants
A 54-year-old developed eczema on her hands and feet due to an allergic reaction to her nickel prostheses.
The symptoms of the unnamed woman disappeared when dentists replaced her implants with specimens of titanium for which she is not allergic.
The woman, who had previously responded to metal jewelry, also had bleeding gums and red skin slices.
A dermatologist initially prescribed an ointment for her, but when this did not alleviate her symptoms, she visited a metal allergy expert.
A 54-year-old woman – who is not mentioned – developed eczema on her hands (photo) as a result of an allergic reaction to the nickel implants that held her dentures in place
She also developed eczema on the leg (photo). A patch test confirmed that she is allergic to nickel, which is often used in dentistry because it is resistant to acidic foods. Over time, small fragments of the metal can break off and enter the bloodstream

It was this specialist who made the connection between her red, itchy skin and her dental work.
The woman underwent an allergy-patch test at Tokushima University, Japan, which showed that she cannot tolerate nickel.
WHAT IS ECZEMA?
Eczema is an inflammatory condition of the skin that leads to redness, blistering, seeping, scaling and thickening.
It usually appears in the first few months of life and affects approximately 10 percent of the baby's.
The cause of eczema is not fully understood, but it is thought to be caused by the skin's barrier to the outside world that is not working properly, which can cause irritants and allergy-inducing substances to penetrate.
It can be genetic because of the condition that often occurs in families.
In addition to affecting their skin, patients may experience insomnia and irritability.
Many factors can make eczema worse. These can be:
- Heat, dust, soap and cleaning products
- Being unwell, like being cold
- Dry skin
There is no cure for eczema, but 70 percent of pediatric patients no longer have the condition in their teenage years.
Patients should avoid known triggers for flare-up and use of emollients.

Metal is often used in dentistry because it is resistant to acidic foods, but it breaks down over time.
Small fragments can then end up in the bloodstream and be taken up elsewhere in the tissue.
The woman first developed a rash on her feet when she was 45, who raised her hands when she was 51.
When she arrived at Tokushima University after ointments did not help, a dental examination showed that she missed several teeth.
The woman underwent a skin-patch test for dental material in the general allergens department. Dr. Yoshizo Matsuka led her therapy.
The results, published in the journal Clinical Case Reports, came back as extremely positive for nickel.
The presence of nickel in the woman's dental implants was confirmed by some of their & # 39; dust & # 39; to determine their metallic composition.
When the implants were removed from the nickel teeth and replaced, her symptoms initially improved.
However, she reported a relapse four months later.
An additional patch test was performed, which showed that it is not allergic to titanium.
The patient's condition improved without treatment, so the authors of the report believed she might have been in contact with another unknown allergen.
Based on the case report, the authors recommend that dentists screen patients for allergens before starting treatment, particularly those with a history of responses to cosmetics or jewelry.
Nickel allergy is a common cause of allergic contact dermatitis, according to the Mayo Clinic.
