Abstract

Background: Glass ionomer cement (GIC) is widely recognized as the prevailing direct esthetic restorative material. In order for a restoration material to be considered effective, possess favorable physical and mechanical properties. Incorporating with hydroxyapatite (HA) can provide these properties. This research is to investigate the impact of integrating HA into GIC on the flexural strength and scanning electron microscopy (SEM) of the fractured surfaces. Methods: The study consisted of 28 samples of GIC, which are fabricated in the shape of rectangular prisms (25x2x2mm). The samples were divided into four groups n=7. Group 1 is a control group (GIC), Group 2 GIC+2%HA, group 3 GIC+2%HA, and GIC+4%HA. The flexural strength of the sample was evaluated by a Universal testing machine, followed by an examination of the fracture surface using SEM. Result: The Brown-Forsythe was used as data analysis to examine the flexural strength values across all groups, resulting in a statistically significant p-value of less than 0.05. The addition of HA does not result in a significant increase in the flexural strength value of the glass ionomer cement (GIC). The integration of microstructure based on scanning electron microscopy (SEM) pictures demonstrates improved visual quality following the incorporation of HA. Conclusion: The addition of HA to GIC did not result in a significant change in flexural strength compared to the control group. However, GIC group with 2% HA exhibited the highest average flexural strength value among all the groups

Abstract

Background: Collagen plays a crucial role in post-extraction wound healing. Thunnus albacares skin, a collagen source synthesized through the papain soluble collagen (PaSC) method with varying NaCl concentrations, is assessed for non-toxicity using the MTT assay on BHK-21 fibroblast cell cultures. This research is to determine cell viability resulting from synthesizing collagen powder from the skin of yellowfin tuna (Thunnus albacares) with varying NaCl concentrations using the papain soluble collagen (PaSC) method. Method: Collagen powder was synthesized by cleaning Thunnus albacares skin measuring 1x1 cm, soaking it in 0.1 M NaOH, hydrolyzing it with CH3COOH, extracting it with papain enzyme, and then dividing the samples into four groups: without NaCl, NaCl 0.9 M, NaCl 1.3 M, and NaCl 1.7 M. Samples were centrifuged (6000 rpm) and followed by freeze-drying. Cell viability was obtained by conducting a cytotoxicity test using the MTT Assay method on BHK-21 fibroblast cells. Result: The percentage of cell viability in groups K, P1, P2, P3, and P4 were 100%, 10.708%, 113.750%, 107.833%, and 105.958%, respectively. The Kruskall-Wallis test yielded a significance value 0.000, indicating a significant difference (p<0,005). The Mann-Whitney test confirmed significant differences between groups. Conclusion: Collagen powder from Thunnus albacares skin with NaCl concentrations of 0.9 M, 1.3 M, and 1.7 M showed no toxic effects, while the group without NaCl showed toxic effects. Collagen powder with a NaCl concentration of 1.7 M yielded ideal results and showed no toxic effects.

Abstract

Background: Application of fissure sealants to young permanent teeth is one of the preventive measures for caries in the field of dentistry. Fissure sealants based on glass ionomer cement (GIC) have the advantage of releasing fluoride. Sodium fluoride and acidulated phosphate fluoride (APF) are remineralization agents because they can increase remineralization by altering hydroxyapatite to fluorapatite and this in turn makes fluorine able to increase pH. Fluoride can prevent caries by increasing remineralization of the enamel that has just been demineralized by acids produced by plaque bacteria. The aim of this study is to compare the shear bond strength fissure sealant based on glass ionomer between sodium fluoride and APF topical fluor applicationMethod: This research applied true experimental design with post test only control group design. The 21 maxillary permanent premolars were distributed into 3 groups, namely the control group (K1), the treatment group added 5% sodium fluoride (K2), and the treatment group added 1.23% APF (K3). Result: One Way ANOVA and post hoc LSD analysis test displayed no significant difference in each group. This could be due to the material used as a conditioner prior to the GIC application. The addition of fluoride ions will inhibit the demineralization process of the enamel produced by the application of conditioner. So it does not rule out that it will interfere with the attachment of the GIC material used as a fissure sealant in this research.Conclusion: There was no significant difference in shear bond strength of fissure sealant based on glass ionomer between sodium fluoride and acidulated phosphate fluoride topical application.
