Recently, new hybrid bioactive restorative materials with the dual advantages of avoiding cavities and encouraging remineralisation have entered the market. Important determinants of the bioactive material's antibacterial qualities are the kind of ions produced and how quickly they are released. The study's objective was to quantify the quantity of ions produced by bioactive materials used in posterior restorations in order to lower the risk of recurrent caries.
For restorative materials utilised in the study, 45 cylindrical specimens were made (nine samples, each group G, measuring 4 mm in thickness and 6 mm in diameter). Giomer (G I), Alkasite Cention (G II), Ketac Molar (G III); Ketac Silver (G IV); and Zirconomer (G V). Following sample preparation as directed by the manufacturer, the specimens were immersed in demineralising and remineralising media (artificial saliva and Coca-Cola) for pH cycling. At 24h, 7, and 28 days (T1, T2, and T3), the number of ions released from each material was measured using energy dispersive X-ray (EDX) analysis.
Comparison between groups was performed by using One Way ANOVA test followed by Tukey`s Post Hoc test for multiple comparisons, while comparison between different intervals was performed by using Repeated Measures ANOV followed by Tukey's Post Hoc test for multiple comparisons. The significant level was set at P ≤ 0.05.
There was a significant difference between all groups regarding all elements and at all times of investigation P ≤ 0.05.
The ions release from bioactive restorative materials is time and composition dependent.
