Abstract

Background: Acanthus ilicifolius L. has antifungal potential and makes it possible to be a candidate for denture cleanser. This study aims to evaluate the effect of effervescent Acanthus ilicifolius L. extract on antifungal properties and flexural strength acrylic after immersion for three duration times.Method: Extracts were made by maceration method with ethanol. For the antifungal test, effervescent Acanthus ilicifolius L extract was prepared by combining the Acanthus ilicifolius L extract 4% and sodium perborate with two ratios, 1:7 and 1:14. The microdilution method was carried out. Effervescent Acanthus ilicifolius L extract 4% with ratio 1:7 was prepared for the flexural strength test. The fifty-four heat-cured acrylic resin (20x10x2.5mm) were fabricated and divided into 3 groups. Group 1 was immersed in aquadest (control); Group 2 was immersed in sodium perborate; Group 3 was immersed in effervescent Acanthous ilicifolius L. extract. Each group was immersed for 15 min, 8, and 56 hours (n=6). The flexural strength test was performed using Universal Testing Machine.Result: Effervescent Acanthus ilicifolius L. extract exhibited antifungal activity which increased in an effervescent Acanthus ilicifolius L extract-dependent manner significantly (0.57 to 0.50 OD). There were no significant differences between sodium perborate, effervescent_AI1 (1:7) and effervescent_AI2 (1:14). The flexural strength was found to be within the range of 66.1 - 68.3 MPa. There were no significant differences between groups (p < 0.05).Conclusion: Effervescent Acanthus ilicifolius L extract with the ratios 1:7 had a good antifungal effect and appropriate flexural strength after immersion for 15 min, 8, and 56 hours.

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.
