A Study of the Effect of Fluoride to Dental Hard Tissue

불소가 치아 경조직에 미치는 영향에 관한 연구

Caries free anterior teeth were rinsed for 10 minutes with 1%, 5% sodium fluoride and 1% stannous fluoride solution three times a day for the period of experiment. And the author measured the concentration of enamel fluoride by means of Mc Cann's Technique. And the results were as follows : 1. There were little difference of enamel fluoride concentration between the teeth treated with 5% sodium fluoride solution. 2. The enamel fluoride concentration shows a tendency of direct proportion in lower concentration of fluoride solution for the period of 10 days. 3. The Enamel fluoride concentration in the group treated with stannous fluoride solution reveals acute elevation in the 5th day of experiment but the trend was not direct proportional in the 10th day of experiment.
