Research on the Mechanical Properties, Fluoride and Monomer Release of a New Experimental Flowable Giomer in Comparison to Three Commercial Flowable Giomers

Abstract

Giomers are hybrid dental materials with controlled fluoride release properties. The aim of this study was to characterise a new experimental flowable giomer (G) in comparison to three commercial flowable giomers: Beautifil flow Plus X F00 (B-F00), Beautifil flow F02 (B-F02) and Beautifil flow Plus X F03 (B-F03), Shofu, Kyoto, Japan. The studied properties are fluoride ion release, residual monomers release and mechanical properties. The data analysis was performed using the ANOVA test and Tukey test for post hoc comparisons between groups. During the first day of the fluoride releasing measurement, the following classification resulted: B-F02 ˃ B-F03 ˃ B-F00 ˃ G and at the end of the investigation period, at 60 days: B-F02 ˃ B-F03 ˃ G ˃ B-F00. The experimental giomer released a lower percentage of total residual monomers than the commercial giomers. The highest value for the mechanical properties was recorded for the commercial giomers. The experimental giomer registered the lowest values for mechanical properties but higher than the imposed standard limit. There were statistically significant differences between the analyzed materials, in terms of fluoride releasing, residual monomer releasing and mechanical properties.

Evaluation of Remineralizing Ability and Mechanical Properties of Two Fluoride Rechargeable Fissure Sealants in Primary Molars: An In vitro Study

“…(11) Bioactive materials provide benefits regarding protection against caries through fluoride release, the capacity to release a protective amount of fluoride is dependent on the hydric degradation of the incorporated bioactive glass. (12,13) These bioactive materials can intervene and stop the progression of carious lesions and allow the damaged tissues to heal when utilized in an early stage of the disease. Such materials have the ability to release, absorb and rerelease calcium, phosphate and fluoride, which will act as a reservoir of ions when the demineralization process initiates and can reverse it.…”
