Publisher : Universitas Airlangga

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).

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.

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..

Background: Since pulp infection plays an important role in the development of periradicular lesions, endodontic treatment should be directed to eliminate bacterial and theirproducts. However, currently 20% of cases of apical periodontitis are not resolved after root canal treatment and therefore required for new root canal disinfection. The most commonly used irrigation material today is NaOCl 2.5%. However, NaOCl has negative effects, including being toxic when the material is injected into the periradicular tissue causing extensive pain, bleeding and swelling. Until now, many drugs come from plants that are still produced from plant extracts. One of the plants that can be utilized is cocoa (Theobroma cacao). Cocoa contains active compounds, such as saponins, tannins, alkaloids, flanonoids, aromatic terpenoids, theobromins and other metabolites. Cocoa husk has been studied to have an antibacterial effect on Porphyromonas gingivalis which is the main bacterial cause of apical periodontal. However, the difference in antibacterial activity between cocoa husk extract and NaOCl 2.5% againstPorphyromonas gingivalis has not been studied. Porpuse:The aim of this study is to compare antibacterial activity of cocoa husk extract and NaOCl 2.5% againstPorphyromonas gingivalis.Method: This research was a laboratory experimental study. Porphyromonas gingivalis were swabbed to nutrient agar medium. Consequently, cocoa husk extract 25% and NaOCl 2.5% were placed in wells of 5mm diameter and nutrient agar medium. The diameter of the zone of inhibition around the test materials was measured after 24 hours.Result:Cocoa husk extract has lower mean inhibitory zone diameter (14.22) than NaOCl 2.5% (16.06). Conclusion:Cocoa husk extract has lower antibacterial activity against Porphyromonas gingivalis compared to NaOCl 2.5%.

Background. About 24-77% of root canal treatment failure cases are caused by infection of Enterococcus faecalis due to the resistance factor and virulence of these bacteria. Calcium hydroxide-based sealer and resin-based sealer are two types of sealer often used for root canal obturation due to their antibacterial properties. But the antibacterial properties owned by calcium hydroxide-based sealer has no effect on Enterococcus faecalis. Therefore, the adjunct of local antimicrobial such as amoxicillin is needed to increase antibacterial activities of root canal obturation materials (sealers) especially for calcium hydroxide-based sealer. Purpose. The aim of this study was to compare the effectiveness of antibacterial activity of calcium hydroxide-based sealer-amoxicillin and resin-based sealer-amoxicillin against Enterococcus faecalis. Methods. This study is an experimental laboratory with post test only control group design using Enterococcus faecalis ATCC 29212. Agar diffusion test was used to check the antimicrobial activity of calcium hydroxide-based sealer-amoxicillin and resin-based sealer-amoxicillin. by measuring the inhibition zone diameter of each treatment. Results. Resin-based sealer-amoxicillin?s diameter of zone inhibition is 37,3 mm and calcium hydroxide-based sealer-amoxicillin?s diameter is 18,7 mm. Conclusion. Antibacterial activity of resin-based sealer-amoxicillin is significantly greater than calcium hydroxide-based sealer-amoxicillin.

Background: Laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation; it can be used for surgery, detoxification, bio stimulation and antibacterial. However, lasers have Biphasic Dose Response (BDR), which is bio stimulation and bio inhibition. To determine if 405 nm laser diode is biocompatible, viability test is necessary before these lasers can be labeled as viable to use in dental therapy. Aim: To prove the variation of radiation time of the 405 nm laser diode radiation can cause bio stimulation and bio inhibition response that affects the viability of BHK-21 fibroblast cells. Method: Viability test was carried out using BHK-21 fibroblast cells which were inserted into 96-well microplate, then radiated with 405 nm laser diode with varying irradiation time of 30s, 60s, 120s, 240s and 480s. After radiation, the cells are then incubated for 24h. Cytotoxicity was observed using MTT assay and ELISA reader. Data was analyzed using the Kolmogorov-Smirnov test, Levene Test, Welch ANOVA, and Tukey HSD. Results: BHK-21 fibroblast cells radiated with 405 nm laser diode with radiation time of 30s, 60s, 120s, and 240s have the same viability as the control cell, while at 480 seconds the viability exceeds that of the control cell. Conclusion: 405 nm laser diode with radiation times of 30s, 60s, 120s, and 240s do not affect the viability of BHK-21 fibroblast cells. Meanwhile, 480s irradiation time of 405 nm laser diode causes bio stimulation response that increases the viability of BHK-21 fibroblast cells.

Background. The main etiology of endodontic treatment failure is caused by bacteries that stay in the root canal. E.faecalis is a bactery that is found as an etiology of endodontic treatment failure. Cell wall of this bacteria is containing Lipoteichoic acid (LTA). LTA can penetrate into the periradicular tissue, act as endotoxin in host and cause periradicular inflammation and destruction. It occurs due to the capability of TGF-ß to enhance the proliferation collagen and MMP-1 to stop the collagen formation. The ability of enterococcus faecalis in enhancing inflamation process cause host can not reach the homeostasis phase and performing an even bigger tissue damage. Purpose. The aim of this study is to know about the expression of of TGF-ß and MMP-1 during the periapical tissue damage due to induction of E.faecalis. Method. This study used laboratory experimental with the post test only control group design. A total of 27 male rats were randomly divided into 3 main groups. Group A (negative control) : every tooth was?nt induced by anything. Group B ( positive control): every tooth was induced only by sterile BHIb and closed by GIC Fuji II as the final restoration. Group C (: every tooth was induced by 10 ?l BHI-b E.faecalis ATCC212(106 CFU), and closed by GIC Fuji II as the final restoration. The animals were sacrificed after 21 days and prepared for histological examination of tissue damage, then we did the immunohistochemistry followed by calculation on the light microscope. Result. The analysis revealed that the expression of MMP-1 increased significantly in group C when E.faecalis was induced. When expression of TGF-ß decreaced significantly in group C rather than group B. Conclusion. From this study we know that the expression of TGF-ß and MMP-1 are make opposite pathway due to chronic apical periodontitis that induced by E.faecalis.

Background: Pulpitis can occur because the deep cavity preparation and it causes increasing of NO levels. Perforated teeth require direct pulp capping (DPC) treatment. The current standard DPC material is calcium hydroxide. However, several studies have found weaknesses of calcium hydroxide that can affect the success of DPC treatment and new, more biocompatible materials are needed. Epigallocatechin-3-gallate (EGCG) in green tea has many benefits, including antioxidant, anticolagenase, anticancer, anti-inflammatory and has the ability of radical scavenging to clean NO so that pulp healing can occur better by increasing the number of fibroblast cells that play a role in wound healing. Purpose: To determine the concentration of hydrogel EGCGs that are effective in increasing the number of fibroblast cell proliferation in the dental pulp perforation of Wistar rats. Method: This research is a laboratory experimental study with a randomized post test only control group design. Samples used in the study were 24 male Wistar rats which were divided into four groups, namely the negative control group and the treatment group were given EGCG 60 ppm, 90 ppm, and 120 ppm and were decapitated on the 7th day after treatment. The maxilla and the 1st molar were taken and decalcified, to process the HPA reading with HE staining. Observations were made using a microscope with a magnification of 400x. Results: There were significant differences in the treatment groups with 60 ppm and 90 ppm hydrogel hydrogels on the results of the Oneway ANOVA difference test (p <0.05). Conclusion: The concentration of hydrogel EGCG which is effective in increasing fibroblast cell proliferation is 90 ppm.
