A 55-year-old man with a dental prosthesis for 3 years had had a chronic relapsing cheilitis for more than 1 year. He was patch tested with the European standard series, his own topicals, and the dental cleanser at 10% pet. A relevant positive reaction ++ was found to the cleansing agent, which contained 20% potassium persulfate. The breakdown of the test confirmed sensitivity to this agent and to ammonium persulfate, both positive (++) at 2.5% pet. The patient was free of symptoms after he had avoided the cleanser. Subsequent chemical investigations performed with a fragment of a used dental prosthesis revealed strong adsorption of persulfate, both on the resin and on the dental tartar. Cleansing agents, adsorbed on tartar and porous resins of worn dental prostheses, should be considered as potential sensitizers and consequently patch tested on such patients with chronic cheilitis.
Functional activity of minor salivary glands is studied in 289 children, 52 of these without signs of cheilitis and 237 with allergic cheilitis at different stages. Three variants of secretion are distinguished: fast, medium, and slow. The ratio of these variants changed in exacerbation of disease in comparison with that in health or remission. The activity of the glands depends on clinical manifestations of cheilitis. Changes in the activity of minor salivary glands determine the clinical picture, localization, and type of involvement in cheilitis.
