\n| Stomatitis<\/td>\n | \n Contact stomatitis for oral hygiene products is a less common presentation than cheilitis even though the products are used inside the mouth rather than on the lips. Presentation can be acute<\/span> or chronic<\/span>. The reaction tends to be generalized<\/span>, affecting the gums (gingivitis), tongue (glossitis<\/span>) and inside the cheeks from a toothpaste or mouthwash. A burning pain in the mouth may be described and on examination there is usually redness with swelling and scaling of the gums, tongue, and \/ or inside of the cheeks.<\/td>\n<\/tr>\n\n| Newspaper eczema<\/span> and contact leucoderma<\/td>\n | Sometimes the allergic reaction spreads beyond the lips to the surrounding skin, presenting as eczema around the mouth (perioral eczema). Periodic leukoderma, whitening of the skin around the mouth, has been reported due to the cinnamic aldehyde present in the patient's toothpaste.<\/td>\n<\/tr>\n | \n| Contact urticaria<\/td>\n | \n Contact urticaria usually presents as immediate swelling of the lips after contact with the allergen<\/span>. This has been reported due to the cinnamic aldehyde present in a mouthwash used by the patient. <\/p>\n However, repeated exposure to a low concentration of the allergen can also cause eczematous cheilitis, despite being due to an immediate type I reaction. Such a situation has been reported due to the mint flavor in a toothpaste. Subsequent exposure to a mint-flavored tooth cleaner at the dentist resulted in immediate lip swelling.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n <\/span>How is a contact allergy to oral hygiene products diagnosed?<\/span><\/h2>\nPatch<\/span> The test is the first investigation for suspected contact allergy. Base<\/span> Standard series are often not helpful in diagnosing contact allergy to dental hygiene products as the common allergens present in these products are not included. Therefore, it is important to add an extended series of toothpaste and the patient's own products.<\/p>\nThere is some discussion in the literature on \u201cas is\u201d toothpaste patch testing due to irritating reactions to detergents and abrasives. However, some studies report that it is possible to distinguish between irritating and allergic patch reactions to toothpaste. The advantage of testing with the patient's product is that in a significant proportion of cases, the only positive reaction is the product. However, patch testing for the product may give a false negative result if the allergen is present in low concentrations.<\/p>\n Some authors recommend confirming product patch test results using a start-restart test or a repeat open application test (ROAT).<\/p>\n Toothpaste companies generally cooperate with dermatologists, providing more information about their product so that the allergen can be identified.<\/p>\n Testing can also be helpful in identifying alternative products that may be safe for the patient.<\/p>\n The cause of an immediate reaction (type I) (contact urticaria) is identified by a skin prick \/ scratch test. However, the low concentration of the allergen in a product may be too low to give a positive reaction. In one case, the prick test with a mint leaf was positive, but a negative reaction was observed with the patient's mint-flavored toothpaste.<\/p>\n The final test is to leave the suspect product and observe the improvement for several weeks.<\/p>\n <\/span>What is the treatment for contact reactions to oral hygiene products?<\/span><\/h2>\nAs with all forms of contact allergy, the best treatment is to avoid the product and the allergen if identified. The reaction should resolve in a few weeks.<\/p>\n \n \n \n \n<\/div><\/div><\/div><\/div>\n <\/span>Allergens reported in oral hygiene products<\/span><\/h2>\n<\/span>Toothpaste<\/span><\/h3>\nThe flavors in toothpaste give the "clean and fresh taste" and cover up the bitter taste of the pyrophosphates in the tartar.control<\/span> toothpaste. And these are the most common ingredients that cause contact allergy. The most common responsible substances are derived from the peppermint plant:<\/p>\n | |
