The Effect of Topically Applied Fluorides on Dental Caries Experience: V. Report of Findings with Two, Four and Six Applications of Sodium Fluoride and of Lead Fluoride

Abstract

The study was designed to determine the minimum number of applications of 2% Na F to achieve maximum reduction in dental caries and to determine the effect of 0.06% Pb fluoride. 4 applications of Na F soln. were necessary, these being preceded by dental prophylaxis. The reduction in caries was approx. 40%. The Pb fluoride soln. was not effective.
