A: A teenage girl had idiopathic white enamel demineralization of her maxillary central incisors; B: After dental prophylaxis with pumice and water, a fine-tapered diamond bur was used with water cooling to remove the superficial layer of the stained enamel; C: Before treatment, the patient received eyeglasses for protection and the teeth were isolated with a rubber dam; D and E: Opalustre microabrasive product was applied and compressed upon the enamel surfaces, using a rubber cup manufactured with enclosed brush bristles specifically developed for this purpose. The microabrasion “slurry” was applied with high torque, but very slow speed, to prevent splattering. The compound was applied three times on each of the three teeth for intervals of 60 seconds. The teeth were rinsed with water/air spray after each application; F: The teeth were then dried with an air syringe and polished with fluoridated prophylaxis paste. A 2% neutral-Ph sodium fluoride gel was applied to the treated enamel surfaces and left in place for 4 minutes; G: The treated incisors are shown immediately after enamel microabrasion
