<![CDATA[Background: Present research studied the surface hardness and roughness dependence on polymerization. Polymerization of composites occurs through chain reaction that is induced by free radicals. Oxygen in the air decreases the excitability of the photo initiator, causing polymerization interference. Oxygen inhibition layer (OIL) is formed on the surface. OIL can be reduced by curing the composite through by application of glycerin to the surface. Purpose: To determine the effect of glycerin on the surface hardness and roughness of nanofill composite. Material and Methods: 64 specimens of composite (Z350 XT, 3M) were prepared using a disc-shaped acrylic. The groups were divided into group A surface hardness (N=32) and group B surface roughness (N=32). Group A1, the specimen was coated with glycerin and light cured for 20 s and group A2, the specimen was exposed to air and light cured for 20 s. Group B1 was coated with glycerin and light cured for 20 s and Group B2 was exposed to air and light cured for 20 s. The specimens were stored in distilled water for 24 h at 370. Measuring with Vickers and surface roughness tester and. Data were statistically analyzed using Mean-whitney U Test. Results: There were statiscally significant difference between the surface hardness and roughness of nanofill composite coated with glycerin and without glycerin (p<0,05) Conclusion: The surface hardness of nanofill composite resin coated with glycerin is higher than composite without glycerin and the surface roughness of nanofill composite resin coated with glycerin is lower than composite without glycerin]]>

<![CDATA[Background: Most soft drinks contain citric acid / phosphoric acid with pH <3.5. Strong acids in the oral cavity cause tooth erosion. Tooth erosion leads to demineralization enamel. Remineralization can prevent demineralization process. One of the commercial remineralization agents is Casein Phosphopeptide-amorphous Calcium Phosphate(CPP-ACP) but it has low solubility and less affordable price. Therefore, a natural ingredients such as theobromine from cocoa extract need to be developed as remineralization agent. Objective: To determine enamel hardness differences due to topical application of theobromine gel and CPP-ACP. Method: incisive crowns were cut off (1x1) cm then planted in cylindrical acrylic resin. All samples were immersed with citric acid for 90 minutes then divided into 3 groups. Group I (control) was immersed with aquades (96 min), group II was applied with theobromin gel 200 mg/l (96 min), group III was applied with CPP-ACP (96 min). By using vickers hardness tester, enamel hardness be measured (15 sec) at 3 points. Results: There were significant differences between the control group, CPP-ACP group, and theobromine gel group. Conclusion: Enamel hardnesse with theobromine gel application is higher than CPP-ACP application..]]>

<![CDATA[Background: Caries is a chronic, slowly progressing disease, with symptoms not detected at the onset of the disease but generally much later. Its initiation is associated with demineralization (calcium and phosphate loss) of subsurface tooth enamel, resulting in the formation of a subsurface lesion. To restore the natural equilibrium, either remineralization must be enhanced or demineralization must be retarded. There are some topical agents that can enhance remineralization such as topical fluor and casein phosphopeptide – amorphous calcium phosphate (CPP-ACP). Purpose: The aim of this study is to analyze the differences of the enamel surface microhardness after application of fluoride varnish and CPP-ACPF. Methode: 27 blocks bovine enamel were devided into 3 groups. Group 1 – control (No surface treatment), group 2 – fluoride varnish and group 3 – CPP-ACPF. Initial surface hardness enamel was measured for all enamel specimens. Artificial enamel carious lesions were created by immersing enamel samples to demineralization solution (pH 4,5) for 72 hours at temperature 370 C. The surface microhardness of demineralized enamel specimens was measured. A caries progression test (pH cycling) was carried out, which consisted of alternative demineralization (3 hours), remineralization with artificial saliva (21 hours) and application topical agent twice a day for 14 days. Then, the last surface enamel microhardness is measured. Result: Group 3 showed significantly highest Vickers hardness number (P<0,05) followed by group 2 and the lowest is group 1. Conclusions: This study proved that enamel surface microhardness after application of CPP-ACPF was higher than fluoride varnish.]]>

<![CDATA[Background: Lactobacillus acidophilus is gram-positive bacteria that produces acids from carbohydrates and causing dental caries. Caries treatment is done by the cavitation of teeth which is preceded by cavity disinfection. The purpose of cavity disinfection is to kill microorganisms and reduce the risk of new carious lesions. Bacterial elimination can be done using chlorhexidine and laser. Chlorhexidine is widely used for cleaning cavities but cannot remove biofilms, tissue debris and has limited elimination of bacteria in the dentinal tubules. Another way to eliminate bacteria is using Photodynamic Therapy (PDT) which consists of photosensitizer and laser. Until now there has not been a single ingredient that is considered to cleanse the cavity thoroughly. There has been no research yet that examine the number of Lactobacillus acidophilus after using chlorhexidine 2%, laser diode (405 nm), and combination of 2% chlorhexidine with laser diode (405 nm). Objective: To compare the decreasing number of living Lactobacillus acidophilus after using chlorhexidine 2%, laser diode (405 nm), and combination of chlorhexidine 2% with laser diode (405 nm). Methods: A total of 24 samples of Lactobacillus acidophilus were divided into 4 groups: (I) chlorhexidine 2%, (II) chlorophyll photosensitizer and 75 seconds irradiation, (III) combination of chlorhexidine2%, chlorophyll photosensitizer, and 75 seconds irradiation. After treatment, the sample was incubated 48 hours and the colony count was calculated for each group. Results of the analysis were carried out by ANOVA and Tukey HSD tests with p <0.05. Results: The average number of group colonies (I) was 35.33 CFU/ml, (II) 16.83 CFU/ml, (III) 9.5 CFU/ml, (IV) 123.33 CFU/ml. Conclusion: The combination of 2% chlorhexidine with diode laser (405 nm) gives the least amount of living Lactobacillus acidophilus bacteria compared with the administration of 2% chlorhexidine and laser diode (405 nm).]]>

<![CDATA[Background : Streptococcus mutans is the most cariogenic microorganism in the oral cavity. Streptococcus mutans has the ability to use dietary carbohydrates, such as sucrose, to synthesize extracellular polysaccharides (glucan and fructan) through glucosyltransferase and fructosyltransferase. Extracellular polysaccharide has a role in promoting the adhesion of bacteria. Chlorhexidine is the gold standard as antiplaque agent but chlorhexidine is not fully able to inhibit the adhesion of bacteria because it has an effect that can increase gtfC and gtfD expression on S. mutans in planktonic form. Temulawak extract (Curcuma xanthorrhiza Roxb.) contains of curcumin, xanthorrhizol, saponin, flavonoid and tannin that have an effect to inhibit activity and secretion of glucosyltransferase and fructosyltransferase. Purpose: The aim of this study is to find out the ability of temulawak extract (Curcuma xanthorrhiza Roxb.) to inhibit adhesion of Streptococcus mutans. Method: This study was designed as an experimental laboratory study with post test only control group design using Streptococcus mutans. Temulawak was extracted using maceration method. The number of bacteria that can perform adhesion to the tooth surface can be determined by performing calculations using formulas plate count method. Result: Temulawak extract (Curcuma xanthorrhiza Roxb.) at concentrations of 25%, 37.5%, 50% and chlorhexidine can inhibit bacterial adhesion of Streptococcus mutans. Conclusion: Temulawak extract at concentration of 50% and 37.5% has the best ability to inhibit the adhesion of bacteria among other treatment groups.]]>

<![CDATA[Background. Pulp necrosis is defined as the irreversible death of pulp tissue. It clinically observed by the destruction of its own tissue. The primary etiology of pulp necrosis is irritation due to bacterial infection. The treatment for pulp necrosis is root canal treatment with a success percentage ranging from 40-93% based on cavities with minimal bacteria that can be sterilized. One method of sterilization using Antibacterial Photodynamic Therapy (aPDT), which uses laser diodes is currently being developed in the field of conservative dentistry, but there are still many differences of opinion regarding the ideal amount of time of laser radiation or photoactivation used to reduce the number of bacteria, especially in root canals. Aim. To determine the effective radiation time of the 650 nm wavelength laser diode with Methylene Blue Photosensitizer in reducing the number of bacterial colonies from necrotic root canals. Method. This research is a laboratory experimental study with 30 samples and 6 groups with different durations of irradiation namely 45, 60, 75 and 90 seconds. Results. It was found that there was a decrease in the number of mixed bacterial colonies within necrotic root canals with the obtained p-value of the ANOVA test results being <0.05. This shows that there is a significant difference between the amounts of mixed bacterial colonies from necrotic root canals in each treatment group. Conclusion. Diode laser radiation with a wavelength of 650 nm with duration of 90 seconds of radiation and Methylene Blue Photosensitizer is an effective time in reducing the number of bacterial colonies from necrotic teeth compared to the duration of radiation of 45, 60 and 75 seconds.]]>
