—At a symposium of tuberous sclerosis and allied disorders, held under the auspices of the New York Academy of Sciences in April 1990, dental enamel pitting was reported to occur in 100% of 29 consecutively examined adult patients with tuberous sclerosis, in 76% (16) of 21 consecutively examined children, and in 8% of a control group of 250 patients without tuberous sclerosis.1See also p 410.Although an association between enamel pitting and tuberous sclerosis has been reported previously,2,3 the incidence of pit recognition in patients with tuberous sclerosis has never been reported to approach 100%. Mlynarczyk1 attributed the high incidence of enamel pitting in patients with tuberous sclerosis to the use of a red food coloring that, when applied to the labial surfaces of the premolar teeth, becomes trapped in the pits, and thus, enhances their recognition. The food coloring used by Mlynarczyk
