The Effect of Silver Diamine Fluoride and Fluoride Varnish on Roughness of Primary Teeth Enamel (An In Vitro Study)

Abstract

Aims: The study aimed to evaluate and compare the effect of fluoride varnish and silver diamine fluoride solution on surface roughness of enamel of primary teeth in vitro study. Materials and methods: A total of (150) primary anterior teeth were used. Enamel blocks were prepared and divided into three groups: Fluoride varnish group n(50), silver diamine fluoride groupn(50), and the control group of deionized water n(50). PH cycle completed at one day and repeated for 10 days. Specimens were kept in demineralizing solution for 3 hours and remineralizing solution for 20 hours. All specimens were washed in deionized water between solutions and placed in artificial saliva for 30 minutes at the end of the demineralization and remineralization process. Surface roughness was measured before and after PH cycle. Results: There was no significant difference between groups before PH cycle while at the end of PH cycle, groups showed highly significant difference at p ≤ 0.01. Also, silver diamine fluoride had the lowest mean value for surface roughness followed by varnish group while the maximum increase in surface roughness belonged to the control group of deionized water. Conclusions: Silver diamine fluoride solution was a significantly better than fluoride varnish in preserving surface characteristics of the enamel of primary dentition.

Surface roughness assessment with fluoride varnish application: An in vitro study

“…Tooth surface roughness is considered one of the determinants in describing the effect of remineralization and demineralization processes on the surface; continuous remineralization can reduce tooth decay. 13 Several studies have proven the potential of fluoride varnish as an effective anti-caries agent. When used correctly, fluoride varnish can reduce the incidence of caries by 40-56% and reduce enamel surface roughness.…”

“…The surface roughness of the anterior deciduous teeth was measured using a surface roughness tester then samples from each group were evaluated for roughness using SEM with a scan area of 200 x 200 µm and a magnification of 1100X. 13,14 Two measurements were made for each sample. The data analysis method used in this study was a paired t-test to find the statistical differences in the increase in roughness of each group (Groups 1, 2, and 3).…”

Impact of Fluoridated Dental Products on Surface Roughness and Morphology of Bleached Tooth Enamel: An In Vitro Study

“…19 All samples were rinsed with deionized water for a minute while not scratching the surfaces before beginning the treatment and bleaching cycle. 20,21 Surface Roughness Test: Using a surface roughness tester (KR220, HFBTE, China), operating with the specimen surface in contact with the stylus, the surface roughness of the enamel surface of the samples was examined. Three distinct profilometric traces were taken on the enamel surface of each specimen, and the results were used to calculate the arithmetic mean deviation of the surface profile or Ra.…”
