<![CDATA[Natural phenomena can inspire people to be able to produce new materials effectively and efficiently, especially in biological tissue. The mechanism mimics nature can increase the potential of tools and materials that we use for applications in dentistry in order to easily adapt the physical, mechanical, and biological or biomimetic. The mechanism of dental materials imitate nature has been conducted on the active ingredient of hydroxyapatite coatings on dental implants. The nature imitating nature can produce the best material because it has good biocompatibility. Bioactive materials, such as hydroxyapatite is a dental material that mimics the mechanisms inspired by nature (biomimetic). Biomaterials are currently developing rapidly is ceramic. Ceramic is a material bioinert. One example is the hydroxyapatite ceramic material that can be used as a repair material defect in the bone caused by disease or trauma. Hydroxyapatite (Ca10(PO4) 6(OH)2) is produced from calcium phosphate cement is a biomaterial that has good potential for application in medicine and dentistry, orthopedics and maxillofacial purpose, because it has favorable properties such as good biocompatibility, bioactive, and osteoconductive. This paper describes the various aspects of biomimetic and its application in dentistry]]>

<![CDATA[Nowadays traditional herbs are become very popular in the medicine world, and also in dentistry. Lerak fruit (Sapindus rarak DC) is one of herbs which is used as a traditional detergent from long time ago. The latest research shows that right now Sapindus rarak DC infusum could be used for an alternative foaming agent as a detergent in tooth paste because of its active substance content that is Saponin. As one of dental health product, this Sapindus rarak DC infusum must be accompanied by non-toxic characteristic before it distributed in the community. The aim of this research is to find out the cytotoxicity of Sapindus rarak DC infusum to BHK-21 cells using MTT assay. This research using post test only control group design. Each group consist of 7 replications in the 96 well microplate. Cultur cells of BHK-21 prepared in media, were divided into 4 group of well. Add 50 µl of Sapindus rarak DC infusum 0,625%; 1,25%; 2,5%; 5% along with BHK-21 cells. Stored the microplate into an incubator for 24 hours. Measurement of cytotoxicity was an optical density or absorbent and read with ELISA reader 620 nm. Value of absorbent in microplate showed the number of living cells in media culture. The increasing concentration of Sapindus rarak DC infusum i.e. 0,625%; 1,25%; 2,5%; 5% would increase the death cells which that means increasing toxicity. The lowest concentration of Sapindus rarak DC infusum has the lowest cytotoxicity potential toward BHK-21 cells using MTT assay. The minimum concentration of Sapindus rarak DC infusum which could be used as an alternative foaming agent in toothpaste and not toxic is 1,25%.]]>

<![CDATA[Maintaining acrylic denture hygiene is a necessary to prohibit the growth of several oral fungi such as Candida albicans. Candida albicans are the main etiological microorganism of denture stomatitis. One of the ways to clean denture is by immersion on synthetic denture cleaner liquid such as oxygenizing denture cleaners. However, synthetic denture cleaner have several limitation due to its biocompatibility on human body especially oral tissue. Chitosan is a derivate of chitin, a natural compound of sea creature exosceleton. Chitosan have antifungi and antibacterial nature. The objective of this study is to evaluate the antifungi efectifity of chitosan 2% on acrylic heatcured and compare it with oxygenizing denture cleaner. Aquades is used as a control. The sample consists of 15 acrylic heatcured bars (10x10x2 mm) prepared by contamination on Candida albicans suspensions at temperature 37°C for 24 hours and immersed on 3 different treatments wich are chitosan 2%, oxygenizing denture cleanser, and aquades as control and then, the solutions are being vibrate and put into sabouraud dextrose agar medium. The colony of Candida albicans counted manually. Result shows, highest mean of Candida albicans colony on aquades group (365,66 CFU/plate), followed by oxygenizing denture cleanser treatment (178,33 CFU/plate). The smallest number colony of Candida albicans are found at chitosan 2% treatment (45,33 CFU/plate). Statistical analysis using ANOVA one way shows F=9.826 and p=0, this means, there is minimal one pair of groups with very significant differential (p<0,01) which are chitosan 2% and oxygenizing denture cleanser compared to aquades as control. The difference between those two treatments also significant. Conclusions of this study is that chitosan 2% solution have a sifnificant effect on prohibiting the growth of Candida albicans colony on acrylic heatcured denture base materials. The effectivity of this solution is significantly higher than oxygenizing denture cleanser treatment.]]>

<![CDATA[Bulkfill composite resin can be applied in “bulk” up to 4mm and it can be cures with LED curing lights in 10 seconds. Time exposure affects the hardness of the composite resin material. This experiment aims to determine differences in exposure time with LED on the hardness of bulkfill composite resin. This experiment is a true experiment. The samples are bulkfill composite resin with diameter of 6 mm and thickness of 4 mm. There were 3 groups of samples (n=5) and cured with LED with intensity 1000mW/cm2. Group 1 was exposed for 10 seconds, group 2 for 20 seconds, and group 3 for 40 seconds. The samples were soaked in distilled water 37oC for 24 hours in waterbath. Microvickers hardness with the load of 100 grams in 15 seconds applied to the samples on the lower and the upper surface. The result found that the ratio of hardness both 10 seconds and 20 seconds, and 20 seconds and 40 seconds are no significant. The ratio hardness of 10 seconds and 40 seconds had significant difference. Based on the research irradiation time effect resin bulkfill composite hardness. It means that the more monomer polymerized the more higher hardness could be achived. The longer exposure time can make increases hardness level.]]>
