Abstract

Contact Sensitivity to Toothpaste Snt,-I wish to report three cases of acute contact sensitivity to a new toothpaste (Close-Up).Each of these patients changed from their regular toothpaste after receiving a free sample of Close-Up through the post.Case 1.-A 30-year-old woman gave a two- month history of a sore mouth with swelling and cracking of the lips.Two weeks before this developed she changed her toothpaste to Close-Up and used it once or twice a day.She showed fissuring of the lips with desquamation and oedema of the surrounding skin.Case 2.-A 36-year-old man developed a weeping eruption at the right side of the mouth with sore gums.He had used Close-Up once a day for three months.There was a right-sided angular cheilitis with swollen gums and desquamation of the tip of the tongue.Case 3.-A 22-year-old woman used Close-Up three times a day for a week.On the sixth day she developed painful ulcers on the inside of her mouth, particularly inside the lower lip.In each case signs and symptoms settled within one week of stopping the use of the new toothpaste.
