Evaluation of fluoride release, pH and antibacterial activity of alkasite restorative material and glass Ionomer Seung-Eun Lee1, Ji-Myung Bae2, Ji-Young Ra1 1Department of Pediatric Dentistry, College of Dentistry, Wonkwang University 2Department of Dental Biomaterials and the institute of Biomaterials and Implant, College of Dentistry, Wonkwang University Purpose: This study aimed to compare the antibacterial activity, pH, and fluoride release of alkasite restorative material (Cention N) and glass ionomer restorative materials (Fuji IX GP, Fuji II LC).
Materials and method: Agar diffusion test was used to determine the antibacterial activity against Streptococcus mutans and Lactobacillus casei. The inhibition zone was measured after 24 hours. The amount of fluoride released was measured on days 1, 3, 7, 14, 21, 28, 42, 56 and 84. The pH was measured after 1, 3, 6, 12, and 24 hours.
Results: All restorative materials showed antibacterial activity. Results of the Streptococcus mutans, showed the follow­ing sequence: CHX > Fuji IX GP > Fuji II LC > Cention N (p<0.05). The Lactobacillus casei results showed the following sequence: CHX >Fuji II LC > Cention N > Fuji IX GP (p<0.05). All materials showed a continuous fluoride release; Fuji IX GP showed significantly higher fluoride release, compared with Fuji II LC and Cention N. The pH test, results showed the following sequence: Cention N > Fuji IX GP > Fuji II LC.
Conclusion: Continuous fluoride release for 3 months and antibacterial activity was observed in Cention N as well as in glass ionomer cements. Cention N showed highest pH among all materials. Further studies are required to evaluate the properties of Cention N in clinical conditions.
