rosin and Stomatitis

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.. 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.
