Comparison of fluoride ion release and alkalizing potential of a new bulk-fill alkasite

Abstract

Aim: This study was conducted to evaluate and compare fluoride ion release by Cention-N (self-cure and light-cure) and conventional glass-ionomer cement (GIC) at different pH and time intervals. Methodology: Cavities of similar dimensions were prepared in mandibular molars and restored with Cention-N (by self-cure and light-cure techniques) and GIC. Samples were stored in deionized water, and the cumulative fluoride ion release and change in pH were assessed utilizing spectrophotometer and pH meter, respectively, at the end of 7 days, 14 days, and 21 days. The data thus obtained were statistically analyzed. Results: All the tested materials released fluoride ions in both acidic and neutral pH at all time intervals, and the fluoride ion release was significantly higher (<0.05) in acidic pH as compared to neutral pH except in GIC. All the groups showed a statistically significant increase in pH in acidic medium, whereas no significant increase was observed in neutral medium. Conclusions: Cention-N (self-cure) has the highest fluoride ion release and alkalizing potential in acidic pH as compared to Cention-N (light-cure) and GIC.

Phosphate Ion Release and Alkalizing Potential of Three Bioactive Dental Materials in Comparison with Composite Resin

“…Porenczuk et al reported that ion release from Activa BioActive after 14 days was less than that from glass ionomer and higher than that from composite. However, over time, glass ionomer specimens showed a greater reduction in ion release than Activa BioActive; their results were in line with the current findings [ 34 ].…”

Comparative evaluation of fluoride release and re-release and recharge potential of Zirconomer Improved and Cention

“…This indicates that when conditions become acidic due to cariogenic challenges, GIC and Cention N would release relatively more fluoride ion. [ 20 ] In our study, the amount of fluoride release decreased with an increasing period. Similar results have been observed by Kiran and Hegde,[ 21 ] Neelakantan et al .,[ 22 ] Cardoso et al .,[ 23 ] Dasgupta et al .,[ 24 ] and Gupta et al .…”

“…Similar results have been observed by Kiran and Hegde,[ 21 ] Neelakantan et al .,[ 22 ] Cardoso et al .,[ 23 ] Dasgupta et al .,[ 24 ] and Gupta et al . [ 20 ] who compared GIC with different restorative materials in a different context.…”

Flexural properties and dentin adhesion in recently developed self-adhesive bulk-fill materials

“…These observations are directly linked to aggressive acid and dehydration treatments conducted on resin-free GICs [37] that contain a substantial amount of water. Considerable filler degradation was observed in Cention N samples, perhaps because of acid attack by highly reactive fillers, namely, calcium fluorosilicate glass fillers, which the manufacturer and some studies [15,40] claim are activated under acidic conditions.…”
