Still, data on the confirmed allergens are rare. This study aimed to identify allergens in dentistry and potential cofactors in sensitization. Method and materials: Patients with suspected allergic reactions in the context of dental (study group) or surgical (control group) procedures were analyzed in a monocentric 3-year retrospective and 2-year prospective file chart analysis between 2018 and 2023. Descriptive statistics and multiple logistic regression analysis were performed.
Results: In total, 129 patients were allocated to the study group and 123 to the control group. Confirmed allergy was less frequent in the study group (10%) than in the control group (28%, P .001). Local anesthetics triggered most dental reactions, but were rarely confirmed allergic (1 of 55 cases). Dental materials and implant material in the control group were confirmed in 16% and 15% of clinically relevant sensitizations, respectively. Multiple logistic regression identified reactions to local anesthetics or dental materials/implant material with a 33.33- or 2.63-fold lower risk of sensitization. A concomitant immune disease was associated with higher risk for a confirmed allergic reaction in dentistry in the cohort (OR 9.12, 95% CI 2.40 to 35.10).
Conclusion: Allergy to dentally administered drugs is rare. Most local anesthetic–triggered reactions were unspecific. Reactions to dental materials resulting in objective symptoms require allergy diagnostics. (Quintessence Int 2025;56:162–170; doi: 10.3290/j.qi.b5907068)
