A Case of Dental Treatment for a Patient with Allergic Reactions to the Self-Etching-Primer for Dentin Adhesive Restoration

Abstract

Dental treatment was carried out on a 6-year old boy with asthma, atopic dermatitis, and tick-moldfood allergy. Before the dental treatment, several allergic tests were performed to check which dental materials were suitable for the patient. He was treated at another hospital with glass-ionomer-cement as the temporary filling materials for caries. After the treatment, he had a routine medical checkup.
He was suspected of having hypersensitivity to dental materials, since the selective synthesis of IgE antibodies for milk had a sharp rise from score 3 to score 6. On the advice of his pediatrician, he came to our hospital to have minute allergic tests and treatments for caries.
We carried out several allergic tests as follows.
1. Patch tests for 18 dental materials
2. Scratch tests for 2 types of local anesthetic solutions
A strong positive skin reaction, such as erythema, edema and vesicle, was elicited with the selfetchingprimer, A positive reaction resulted from the etching agent. The anesthetic solutions and the other dental materials (including glass-ionomer-cement) did not induce skin irritation.
We suspected that he was sensitive to the self-etching-primer. We, therefore, did not use composite resin as the filling materials. Silver alloy inlay and titanium primary crowns were selected for the dental treatment.
No untoward event was noted throughout our dental treatment, and no adverse reactions were noted postoperatively.
