Clinical evaluation of sodium fluoride chewable tablets in dental caries

Chewable tablets containing low dosage fluoride content were prepared using two varieties of celluloses and their in vitro parameters were evaluated. An eighteen month clinical trial revealed that both these formulations were effective in controlling the caries. However, ethyl cellulose is proved to be superior to methylcellulose as a controlled release matrix material in controlling caries. Thus this study recommends ethylcellulose matrix tablets containing low fluoride content is an efficacious and cost effective drug device in controlling dental caries.
