Abstract

Introduction: Caries prevention and eradication has been the greatest dentists’ challenge world wide. As fluoride has been identified as one of the protective factors that tilt the caries balance towards the positive side. Therefore, fluoride releasing materials were elaborated with the purpose of reducing the incidence of caries.
Objectives: to compare between the amount of fluoride releasing and recharging capacity of fluoride releasing nano-hybrid composite and resin reinforced glass ionomer.
Materials and methods: Two hundred and seventy two round specimens (n=136 for each material) were used to prepare the required samples. Each 4 specimens immersed in 5 ml of artificial saliva were considered as one sample of total number sixty eight samples (n=34 for each group).The samples were divided randomly into two groups according to the materials used: Group І (experimental): reliaFIL light cure nano-hybrid composite and Group Π (control): Riva light cure resin reinforced glass ionomer. The amount of fluoride released in each sample was recorded on day 1, 7 and day 15 by using fluoride ion selective electrode. After 15 days each group was divided into 2 subgroups (n=17): Subgroup A: experimental subgroup (treated with ClinproTM white varnish) and Subgroup B: control subgroup (no fluoride varnish treatment). The amount of fluoride re-release was recorded at the same time intervals. Then, the recharge capacity was calculated as the difference in the fluoride release between experimental and the control subgroups.
Results:As for the fluoride release there was a statistical significant difference between two groups (P=0.05). However, there was no significant difference between the two groups in the fluoride re-release and recharge capacity (P=0.05).
Conclusions: Fluoride releasing nano-hybrid composite had demonstrated a capacity of fluoride release and a recharge capacity comparable to resin reinforced glass ionomer.
