[A chewing gum with mineral additives]

Finely dispersed hen egg shell was added to a new chewing gum as a mineral component. The studies carried out in 28 schoolchildren have shown that 15 min chewing of this gum results in a marked elevation of salivary Ca levels and in improvement of the hygienic status of the oral cavity. This fact recommends this chewing gum as an additional means for care of the oral cavity for both hygienic purposes and for improving the mineralizing potential of the saliva.
