Abstract

Introduction: Enamel is the hardest substance in the human body and serves as the wear-resistant outer layer of the dental crown. Demineralization releases mineral ions which cause a decrease in the enamel surface hardness. Demineralization could be neutralized to recover minerals, and this process is called remineralization. Almond milk was an alternative to cow’s milk, supporting tooth enamel surface remineralization. Purpose: To determine the effect of almond milk on enamel hardness. Methods: Twenty maxillary premolars were divided into group A (control) and group B (almond milk). Before treatment, samples were soaked in 1% citric acid. Enamel hardness was tested with Vickers Hardness Tester. The statistical tests used in this study were Paired t-test and Independent Sample t-Test. Results: The results of the paired sample test got significant results in groups A and B in the comparison of pretest - 1% citric acid, and 1% citric acid - posttest, which means that there was a significant difference in enamel hardness values. However, the results obtained were not substantial in groups A and B in the posttest- pretest comparison. There was no significant difference between Group A and Group B in the independent sample test results. There was an increase before and after, but it was not much different when compared to the control. Conclusion: Almond milk can increase enamel surface hardness but cannot reverse the initial enamel surface hardness value.

Abstract

Introduction: Unsuccessful elimination procedures of Gram-positive bacteria (Enterococcus faecalis) often lead to failure of endodontic treatment. It is necessary to use irrigation solutions to eliminate it from the root canal. The leaves of Pineapple (Ananas comosus) that are widely cultivated in Prabumulih have antibacterial properties due to active compounds such as bromelain enzymes, flavonoids, phenols, saponins, tannins, and alkaloids and have potential as an alternative material for root canal irrigation. Purpose: This study aimed to determine the antibacterial potency of Prabumulih pineapple leaf extract (Ananas comosus) against E. faecalis. Methods: This is an in vitro quasi-experimental laboratory study with a post-test-only control group study design. The test group consisted of Prabumulih pineapple leaf extract at concentrations of 1.56%, 3.125%, 6.25%, and 12,5% obtained using the maceration method. The positive control was NaOCl 2.5%, and distilled water was the negative control. The antibacterial activity of the extract using the disc diffusion method for the inhibition zone test, the dilution method for the minimum inhibitory concentration (MIC) test, and solid dilution for the minimum bactericidal concentration (MBC) test. Results: It showed that Prabumulih pineapple leaves extract has antibacterial potency against E. faecalis with the largest average inhibition zone at a concentration of 12.5% (2.324 mm), MIC at a concentration of 12,5%, and MBC also at a concentration of 12,5%. Conclusion: Prabumulih pineapple leaf extract has antibacterial potency against Enterococcus faecalis.

Abstract

Introduction: Enterococcus faecalis is a Gram-positive bacterium commonly found in cases of failed root canal treatment. Irrigation material with antibacterial effects are important in supporting the success of root canal treatment. Pineapple peel as a natural ingredient is reported to contain compounds such as flavonoids, saponins, tannins, and bromelain enzymes that have been proven antibacterial effects. Purpose: To determine antibacterial potency of pineapple peel extract (Ananas comosus) with concentrations of 1.56%, 3.125%, 6.25% and 12.5% against E. faecalis. Methods: In vitro quasi-laboratory experimental study with a post-test only control group design consisting of pineapple peel extract with concentrations of 1.56%, 3.125%, 6.25%, 12.5%, and aquadest as negative control with repetition 6 times. The inhibition test was determined using the disc diffusion method on Mueller-Hinton Agar media. The MIC value can be determined using the broth dilution method and the MBC value can be determined using the solid dilution method. The inhibition zone diameter data were analyzed using One Way ANOVA test and Post Hoc Tukey test. Results: Pineapple peel extract with concentrations 12,5% had the largest mean inhibition zone, which is was 3.13 mm. The MIC and MBC values of pineapple peel extract were determined at a concentration of 6.25%. Conclusion: Pineapple peel extract (Ananas comosus) has antibacterial potency against Enterococcus faecalis.
