The tooth enamel colour play an important role in esthetics. The discoloured teeth could be due to the using of boild Piper betle extract as a mouth wash. Up to now many people in Indonesia using the boiling Piper betle extract to manage oral diseases and to prevent tooth decay. The aim of this in vitro study are to know the effective concentration and application time of this agent to change the enamel colour. Fresh Piper betle leaves were processed to get 4 differents concentration (50, 33, 25, and 5%). Aquabidest was used as negative control. Every concentration was studyed using 2 maxillae premolar teeth in 24, 48, and 72 hours application times. 30 good condition teeth were used in this research.    The results showed that every concentration gaves discoloured changes. The optimal concentration and duration are 25% and 48 hours. It is concluded that using of this gargling agent must be intermittent. It can be suggested to use this agent only once or twice daily, each for 2 until 3 minutes gargling.

Probiotic consumption and repeated probiotic intake have shown promising results as adjunct therapies in prevention and alleviation of some chronic disease conditions in the gastrointestinal tract. Recent evidence suggests that probiotics may also be beneficial in preventing oral diseases. An efficient probiotic candidate in the mouth, however, should not impose any risk to oral tissues, such as acid demineralisation of tooth enamel because of sugar fermentation. The aim of the present in vitro study was to evaluate the utilisation of some sugars and sugar alcohols by yogurt starter Lactobacillus delbrueckii subsp. bulgaricus strains and to assess the influence of these carbohydrate sources on cell surface properties. For comparsion, a commercially available probiotic, Lactobacillus rhamnosus GG, was used. The results showed that lactose, glucose and fructose were readily metabolised by all strains tested. However, strain-specific metabolic patterns were observed when other sugars and sugar alcohols were used as sole carbohydrate source in the growth medium. Surface properties of the bacteria such as hydrophobicity and surface-associated proteins appeared to vary with the carbohydrate content of the growth medium. Based on these results it can be concluded that among the L. delbrueckii subsp. bulgaricus strains probiotic candidate strains are available that warrant further studies due to their inability to ferment sugars with pronounced cariogenic properties.

Abstract Objective This study evaluated four types of pH adjustment of the coconut water (CW) on viability of human fibroblasts (HFF). Material and method Natural and industrialized CW were adjusted to pH 7.0 using: (1) Sodium Hidroxide (NaOH), (2) Sodium bicarbonate (NaHCO3), (3) Triethanolamine (C6H15NO3), (4) 2-Amino-2-Methil-1-Propanol (C4H11NO). Fibroblasts were plated at 2×104/ well in 96 well plates and maintained in the CW solutions for 2 h and 4 h. Positive control was represented by HFF maintained in DMEM and the negative control by tap water. Cell viability was analyzed by MTT formazan method. Data were analyzed by 3-way ANOVA followed by Tukey’s and Dunnet’s test. Result There are no significant effect on the cell viability regarding type of CW, period of evaluation, and the interactions between CW and period of evaluation, CW and pH adjustment method, pH adjustment method and period of evaluation (p>0.05). Conclusion The product used for CW pH adjustment did not influenced HFF viability, thought there are a tendency of better performance in natural CW.

Background: We aimed to prepare a nanofluid, containing f-MWCNTs, and investigate the antibacterial efficacy of f-MWCNTs+ ciprofloxacin (cip) on Klebsiella pneumoniae by evaluating the virulence gene expression. Methods: This study was carried out from 2019 to 2020, in the Department of Mycobacteriology and Pulmonary Research, Pasteur Institute of Iran. The nanofluid containing antibiotic and f-MWCNTs were prepared by the ultrasonic method. The minimum inhibitory concentrations (MICs) of ciprofloxacin and f-MWCNTs were determined using the broth micro dilution MIC tests. For examining the antibacterial effects, the expression level of virulence genes, under the influence of f-MWCNTs, was evaluated by a real-time PCR. Results: The effect of 8 µg/ml ciprofloxacin + 400 µg/ml f-MWCNTs, completely inhibited the growth of the resistant isolate of K. pneumoniae, while, in the ATCC 700,603 isolate, 2 µg/ml ciprofloxacin with 100 µg/ml f-MWCNT could inhibit a bacterial growth. In the resistant K. pneumoniae clinical isolate, after f-MWCNT+cip treatment, the expression of fimA, fimD, wza, and wzi genes was significantly downregulated, compared to the ciprofloxacin treatment, and upregulated, compared to the negative control. For the ATCC 700,603 isolate treated with f-MWCNT+cip, the expression of fimA, fimD and wza virulence genes showed upregulation, compared to the negative control and downregulated in comparison with the ciprofloxacin treatment. Conclusion: Simultaneous treatment of resistant isolate of K. pneumoniae with f-MWCNTs +antibiotic could improve the effectiveness of antibiotic at lower doses, due to the reduced expression of virulence genes in comparison with antibiotic treatment, besides the increased cell wall permeability to antibiotics.

Malaria is a disease that occurs in tropical countries like Indonesia. The incidence of malaria in the world is still quite high and the occurrence of cases of Plasmodium resistance to antimalarial drugs and the widespread of resistance have prompted researchers to look for new antimalarial drugs, especially from natural materials. Betel leaf (Piper betle Linn.) And sunflower leaf (Helianthus annuus L.) have long been used by the people of Indonesia as an antimalarial drug. The purpose of this study was to determine antimalarial activity through inhibition of heme polymerization and determine secondary metabolite compounds by phytochemical screening from betel leaves and sunflower leaves. The heme polymerization inhibition activity assay was carried out by the in-vitro method using a microplate reader at 415 nm and 630 nm wavelengths. IC50 values of betel leaf extract and sunflower leaf were 178.67 μg/ml and 160.10 μg/ml, respectively. Phytochemical screening results from betel leaf showed the presence of flavonoids, polyphenols, tannins, quinones, saponins, and monoterpenoids-sesquiterpenoids, while sunflower leaves contain alkaloids, polyphenols, flavonoids, steroids and monoterpenoids-sesquiterpenoids.Keywords: Piper betle Linn., Helianthus annuus L., Malaria, Heme Polymerization

Purpose: To assess the antimicrobial effects of different natural and semi-natural mouthrinses on isolates of S. mutans obtained from the saliva of Saudi children and reference strains of S mutans (ATCC 25175). Study design: Saliva samples were collected from 20 children. Natural and semi-natural mouthrinses included were herbal mix mouthrinse, cranberry mouthrinse, chlorhexidine digluconate mouthrinse, cranberry extract mixed with chlorhexidine digluconate mouthrinse, chlorhexidine digluconate mouthrinse with alcohol (positive control), and distilled water (negative control). The microbiological examination tests were minimal inhibitory concentration, minimal bactericidal concentration, and zone of inhibition for the saliva isolates of S. mutans while zone of inhibition test only for reference strain of S. mutans. Results: For reference strain in a comparison with the distilled water, the herbal mix, cranberry, cranberry mixed with chlorhexidine, chlorhexidine, and chlorhexidine with alcohol showed significantly increased zones of inhibition by 36.38, 36.25, 26.13, 17.75, and 12.38, respectively. For saliva isolates in a comparison with the distilled water, the herbal mix, cranberry, cranberry mixed with chlorhexidine, chlorhexidine, and chlorhexidine with alcohol showed significantly increased zones of inhibition by 38.00, 34.25, 22.94, 16.50, and 16.44, respectively. Chlorhexidine with alcohol showed significantly lower minimum inhibitory and bactericidal concentration than the other groups. Conclusions: Herbal mix and cranberry mouthrinses could be effective natural alternative to chlorhexidine mouthrinse with or without alcohol in affecting tested parameters.

Introduction: The technique of sealing is a widely accepted procedure for prevention of caries. The aim of our in vitro study was to compare the effect of two different curing units (traditional LED source and innovative laser diode lamp) on the integrity of fissure sealant material and its interface with tooth enamel. Materials and methods: Sixty healthy third molars were randomly assigned to two groups. In group A were teeth intended for polymerization by LED B lamp, and group B comprised teeth to be polymerized by an innovative laser diode. Both groups were treated with the traditional sealing technique, subjected to a metallization process, and analyzed by scanning electron microscope. Results: Micro-gaps between the sealant and the enamel were found in specimens in both A (43%) and B (40%) groups ( p=0.793), and sealant shrinkage was seen. Significant differences between the groups emerged in the percentage of perimetric micro-erosion sites (80% vs. 100%, p=0.010) and the presence of holes and micro-bubbles on the sealant surface (21% vs. 63%, p=0.001). Conclusions: Although macroscopic clinical polymerization occurred with both instruments, the microscopic evaluation showed significant differences between the studied groups in terms of perimetric micro-erosion sites and micro-bubbles, which were higher in laser-cured samples.
