Allergic contact stomatitis from colophony.
Colophony is an ubiquitous contact sensitizer which may be present in dental materials, such as periodontal dressings, impression materials, cements, fix adhesives and varnishes. Exposure to a sensitizer in a hypersensitive person may initiate an allergic contact dermatitis/stomatitis. This usually occurs after direct skin/mucosa contact with the sensitizer. This paper reports the case of a colophony hypersensitive male who developed contact stomatitis after dental treatment with a colophony-containing product.


CONCLUSIONS
Sensitizing colophony is present in Duraphat 2.26%F varnish, a fluoride varnish used all over the world. A case of hypersensitivity to Duraphat 2.26%F varnish is presented in a patient who, at the initial visit, indicated only an allergy to sticking plasters.
