“…Similarly, partial caries removal followed by ART restorations with GIC controls caries progression by providing proper conditions for the reorganization of the carious dentin left at the cavity floor. Through cavity sealing, the biofilm removal becomes easier during tooth brushing [Hahnel et al, 2017]. Although GIC also releases fluoride, this release is very low when compared to SDF (38%, 44,800 parts per million, ppm, fluoride) and 5% fluoride varnish (22,600 ppm F).…”

A systematic review was performed to evaluate the efficacy of silver diamine fluoride (SDF) in controlling caries progression in children when compared with active treatments or placebos. A search for randomized clinical trials that evaluate the effectiveness of SDF for caries control in children compared to active treatments or placebos with follow-ups longer than 6 months was performed in PubMed, Scopus, Web of Science, LILACS, BBO, Cochrane Library, and grey literature. The risk of bias tool from the Cochrane Collaboration was used for quality assessment of the studies. The quality of the evidence was evaluated using the GRADE approach. Meta-analysis was performed on studies considered at low risk of bias. A total of 5,980 articles were identified. Eleven remained in the qualitative synthesis. Five studies were at “low,” 2 at “unclear,” and 4 studies at “high” risk of bias in the key domains. The studies from which the information could be extracted were included for meta-analysis. The arrestment of caries at 12 months promoted by SDF was 66% higher (95% CI 41-91%; p < 0.00001) than by other active material, but it was 154% higher (95% CI 67-85%; p < 0.00001) than by placebos. Overall, the caries arrestment was 89% higher (95% CI 49-138%; p < 0.00001) than using active materials/placebo. No heterogeneity was detected. The evidence was graded as high quality. The use of SDF is 89% more effective in controlling/arresting caries than other treatments or placebos. The quality of the evidence was graded as high.

“…Fluoride releasing materials can prevent caries formation under restorations due to the different properties of f luoride, such as suppressing demineralization, enhancing remineralization, and interacting with many metabolic processes of bacteria. 11,12,24 However, when selecting a material to restore teeth, one of the main considerations is also the mechanical properties of the material. The flexural strength test is commonly used to evaluate the mechanical properties of materials in laboratory conditions.…”

“…25 Besides, the increased surface roughness might cause a decrease in mechanical properties of the materials and be a predisposing factor to microbial colonization. 24,26 Therefore, the objective of this study was to evaluate the effect of ionizing radiation from high energy X-ray on the properties of fluoride releasing restorative materials by assessing fluoride release, surface roughness, flexural strength, and chemical compositions of the materials' surface.…”

The purpose of this study was to evaluate the effect of ionizing radiation from high energy X-ray on fluoride release, surface roughness, flexural strength, and surface chemical composition of the materials. The study groups comprised five different restorative materials: Beautifil II, GCP Glass Fill, Amalgomer CR, Zirconomer, and Fuji IX GP. Twenty disk-shaped specimens (8x2 mm) for fluoride release and 20 bar-shaped specimens (25 x 2x 2 mm) for flexural strength were prepared from each material. Each material group was divided into two subgroups: irradiated (IR) and non-irradiated (Non-IR). The specimens from IR groups were irradiated with 1.8 Gy/day for 39 days (total IR = 70.2 Gy). The amount of fluoride released into deionized water was measured using a fluoride ion-selective electrode and ion analyzer after 24 hours and on days 2, 3, 7, 15, 21, 28, 35, and 39 (n = 10). The flexural strength was evaluated using the three-point bending test (n = 10). After the period of measurement of fluoride release, seven specimens (n = 7) from each group were randomly selected to evaluate surface roughness using AFM and one specimen was randomly selected for the SEM and EDS analyses. Data were analyzed with two-way ANOVA and Tukey tests (p = 0.05). The irradiation significantly increased fluoride release and surface roughness for Amalgomer CR and Zirconomer groups (p < 0.05). No significant change in flexural strength of the materials was observed after irradiation (p > 0.05). The ionizing radiation altered the amount of fluoride release and surface roughness of only Amalgomer CR and Zirconomer. The effect could be related to the chemical compositions of materials.

“…This is difficult to achieve in elderly patients and noncooperative children with high caries risk or when the rubber dam is impossible to install. 28 The GIC can be a satisfactory alternative therapy in these cases with a superior outcome compared with composites, especially with the release of fluoride, which is an important factor in the prevention against secondary caries. 29 "EQUIA" is considered as less techniquesensitive than resin composite; it is moisture-tolerant and allows a bulk filling technique since it does not undergo volumetric shrinkage during polymerization, unlike composites.…”
