Aim: This study aimed to assess and compare the fluoride release and recharge capacity of CentionN, Zirconomer and Gc Gold Label 9 Extra.
Methodology: Disk-shaped specimens (n = 12) of CentionN, Zirconomer and Gc Gold Label 9 Extra were prepared according to manufacturer's instructions. After setting, each specimen was dipped in a plastic tube containing 5ml deionized water and incubated at 37°C ± 2°C. Every 24 h, the samples were placed in fresh 5 ml deionized water. Mean fluoride release (in ppm) from each material, on day 1 and day 6 was calculated using a spectrophotometer. On day 6, the specimens were recharged with 0.2% neutral NaF solution for 2 min and the fluoride release on day 7 was determined.
Results: Cention N released significantly greater amount of fluoride on day 1 and day 6, than zirconomer and Gc Gold Label 9 Extra (P < 0.001). Cention N showed a better recharge capacity than zirconomer and Gc Gold Label 9 Extra (P < 0.001).
Conclusions: Cention N with a higher fluoride release and recharge capacity can be used as a posterior restorative material in patients with high caries risk, thereby inhibiting secondary caries
