Abstract

Background: Topical fluoride use result in re harden or arrest lesions of dental caries in dentine. Silver diamine fluoride (SDF) can be employed to inhibit and arrest dental caries. The use of laser in caries prevention was suggested by used Neodymium doped yttrium-aluminium-garnet (Nd: YAG) laser as an adjunct to conventional caries prevention therapies.

Aim: The aim of this research was to investigate the effect of selected topical fluoride materials, acidulated phosphate fluoride (APF), Silver diamine fluoride (SDF), Stannous fluoride (SnF2) with or without Nd-YAG laser application on Fluoride uptake of dentine, in vitro.

Materials and methods: The samples in this study include 55 maxillary first premolar teeth, distributed into 11 groups, and each group involved of five specimens. Before the surface treatments, all the specimens in the 11 groups underwent a pH cycling procedure to induced caries like lesion in dentine specimen for five days, and then 2 days in remineralization solutions. Fluoride measurements were accomplished by an ion-selective electrode.

Results: Results presented after treatment with different agents, a marked increase in fluoride uptake for the groups treated with SDF+Laser, SnF2, Laser+SnF2, Laser+APF. While a severe increase in fluoride uptake for the group treated with silver diamine fluoride (SDF) alone. Conclusion: Treatment of dentine surface with Silver diamine fluoride alone gave the best result regarding as topical fluoride application.
