ABSTRACT Rosin is a ubiquitous contact sensitizer which may be present in dental materials such as periodontal dressings, impression materials, cements, and cavity varnishes When a hypersensitive person is exposed to a sensitizer, allergic contact dermatitis/stomatitis may develop, most commonly after direct skin/mucosa contact with the sensitizer. However, widespread dermatitis may develop after systemic administration of the sensitizer, and this paper reports the case of a rosin-hypersensitive man who developed widespread eczematous dermatitis after dental treatment with a rosin-containing product.

    ABSTRACT: Oral mucous membrane contact dermatitis (or contact stomatitis) is relatively rare. In general, the mucosa is more resistant to primary irritants, and is not as readily sensitized as the skin. The oral mucosa is also constantly bathed in saliva, which washes sensitizers from the mucosal surface and prevents adequate contact. Furthermore, abundant mucosal vasculature allows for rapid absorption and clearing of allergens. Nevertheless, contact reactions can occur on the oral mucous membrane. Contact sensitivity has been described as a factor in recurrent oral ulceration43 and 32 and oral lichenoid reactions.52 As with other types of contact dermatitis, allergic contact dermatitis may be difficult to distinguish from irritant contact dermatitis, and it may also mimic oral changes of vitamin deficiency, certain anemias, uremic stomatitis, and candidiasis.18 Although the prevalence of allergic contact sensitivity in the mouth is unknown, a number of substances have been reported to cause oral symptoms.

    ABSTRACT: Allergic contact dermatitis (ACD) in dentistry may affect dentists and orthodontists, technicians, nurses and patients. Changes to dental practice in recent years have altered the reported frequencies of allergens causing ACD in both dental personnel and patients. Allergic contact dermatitis to medicaments, metals and glutaraldehyde were previously common allergens in dentistry; however, widespread adoption of rubber gloves by staff has resulted in a significant increase in ACD to glove allergens in both dental staff and their patients, while affording protection against the traditional allergens. Both public concerns about potential toxicity of metals in oral restorations and a greater demand for cosmetic dentistry, have resulted in greater use of acrylics and resins by dental personnel, exposing them to highly allergenic materials. Dermatologists need to be aware of the newer allergenic materials used in dentistry in order to correctly manage skin diseases in this high-risk group.

    ABSTRACT: OBJECTIVE: The aim of the present controlled study was to investigate a possible relationship between contact allergies to potential allergens and oral lichen lesions. METHODS: Eighty-three patients with oral lichen lesions (OLL) and control groups of age- and gender-matched dermatitis patients (DP, n = 83) and patch-tested dermatitis patients randomly selected from files (PSFF, n = 319) were included in the study. OLL and DP groups were patch-tested epicutaneously and examined intraorally. RESULTS: The frequencies of contact allergy to mercury and carvone were statistically higher in the OLL group than in the DP group. Surfaces of amalgam and composite restorations were statistically more frequent in the OLL group compared to the DP group. Contact allergy to nickel and colophony, the latter with a statistically significant difference, was more common in the DP group. The numerical difference found for nickel allergy was, however, not significant comparing the OLL and PSFF groups. CONCLUSION: Contact allergy to mercury was overrepresented in patients with OLL and has been reported in previous studies, but the present finding of an overrepresentation of contact allergy to carvone in patients with oral lichen lesions has not been reported previously. CLINICAL RELEVANCE: Carvone, in addition to mercury and gold, as previously suggested, can be one of the causative or maintenant factors for oral lichen lesions. Carvone-hypersensitive patients with oral lichen lesions should therefore avoid carvone-containing products for oral use.
