Abstract

Objective: Calcium hydroxide is widely used as pulp-capping material, but it is resistant to Aggregatibacteractinomycetemcomitans bacteria. Because of this deficiency, many researchers are considering usingalternative natural ingredients, such as propolis. Propolis has been widely used in dentistry due to itsproperties and because it has active ingredients that can act as antibacterial agents. It is hoped that whencalcium hydroxide and propolis are combined, the combination can overcome the disadvantages. The aim ofthis study was to determine the dosage effectiveness of the combination calcium hydroxide-propolis as aninhibitor for A. actinomycetemcomitans biofilm. Material and methods: The sample was divided into fivegroups. The positive control group is a combination of calcium hydroxide-sterile aquadest, and the negativecontrol group is A. actinomycetemcomitans bacteria. Group I is a combination of calcium hydroxidepropolis with a ratio of 1:1, group II has a ratio of 1:1.5, and group III has a ratio of 1:2. Each group consistsof five replications. Combination of calcium hydroxide-propolis and A. actinomycetemcomitans bacterialsuspension was incubated for 2x24 hours then washed three times using PBS. Furthermore, 2% of crystalviolet was used for staining and covered with aluminum foil and then incubated for 15 minutes. Isopropanol200µL was added, followed by a measurement of OD with an ELISA reader, and the OD values werecalculated using an inhibition biofilm formula. Results: Group II has the largest mean inhibition with 76%compared to groups one and three. Conclusion: A combination of calcium hydroxide and propolis with aratio of 1: 1.5 is more effective than 1:1 or 1:2 to inhibit A. actinomycetemcomitans biofilm.

Abstract

Background: Propolis is a resinous hive product collected by bees from tree buds and mixed with secretedbee wax to both avoid bacterial contamination in the hive and seal it. It is known to have a wide spectrumof pharmacological properties, including anti-inflammatory, antioxidant, antibacterial, antiviral, and antifungal abilities. Apoptosis tests were performed on odontoblast cells in rats (Rattus novegicus) to assessthe viability of propolis extract and caffeic acid phenetyl esters (CAPE) as alternative candidates for pulpcapping agents in conservative dentistry treatment. Objective: To examine the apoptosis activity of propolisextract and CAPE as capping materials on odontoblast cells. Methods: This study was designed as a posttest only control group laboratory experiment. The rats were randomly divided into three groups. Pulpexposures were performed on the occlusal surface of the right maxillary first molars. In the first group, thecontrol group, glass ionomer cement (GIC) was directly applied to the pulp exposure. In the second group,the sample group, propolis extract was applied to the pulp exposure, and in the third group, CAPE wasapplied to the pulp exposure. All cavities were then filled with GIC as a permanent filling. Animals weresacrificed on the first and fourteenth days. The direct counting method of histological examination was basedon the apoptotic odontoblasts, using the terminal deoxyribonucleotidyl transferase dUTP nick end labeling(TUNEL) assay technique. Result: There was a greater number of apoptotic odontoblasts in the controlgroup, followed by the CAPE group and, lastly, the propolis extract group. Conclusion: The apoptosisactivity of the propolis extract is lower than that of CAPE.

Abstract

Background: Lactobacillus acidophilus, Gram-positive bacterias that enterthe dentinal tissue during the carious process are suspected to influence the immune response in human dental pulp. Odontoblasts situated at the pulp dentin interface are the frst cells encountered by these bacteria and have an important role in this response. Lipoteichoic acid (LTA), a wall component of Gram-positive bacteria, triggered the activation of the odontoblasts. LTA upregulated the expression of its own receptor TLR2, as well as the production of proinflammatory cytokineTNFα. Propolis is a resinous material that holds a great potential as an antiinflammatory agent. Present studies have shown that propolis has a reduction effect towards the proinflammatory cytokines expression and favor pulp healing.Purpose: To reveal the moleculer mechanism of propolis stimulation onodontoblast like cells, induced by inactive Lactobacillus acidophilus.Methods: This review was presented in odontoblasts like cells culture induced by inactive Lactobacillus acidophilus and exposed to propolis extract.

Abstract

Background: In deep dentinal caries cases, bacteria mostly found are Lactobacillus acidophilus classified as gram positive bacteria and as facultative aerobes producing glucosyltransferase (GTF) enzyme. GTF enzyme can alter sucrose into glucans. Glucan is sticky and insoluble in water. As a result, GTF enzyme can facilitate plaque formation and microorganism colonization on tooth surface. In addition, Lactobacillus acidophilus also can form acid leading to demineralization of organic and inorganic materials, resulting in dental caries. Multidrug-resistant phenomena, on the other hand, have led to the use of natural resources, one of which is propolis as an antimicrobial material and as a new anti-infective therapeutic strategy. Propolis is a resinous substances collected by worker bees (Apismellifera) from barks and leaves of plants. Propolis has a complex chemical composition and biological properties, such as antibacterial, antiviral, antifungal, anti-inflammatory, and antitumor. Purpose: This research aimed to reveal anti-glucan effects of propolis ethanol extract generated from honey bee, Apis mellifera spp on Lactobacillus acidophilus bacteria. Method: Before antiglucan test was conducted, glucan-formation test was performed on Lactobacillus acidophilus bacteria using SDSpage. Meanwhile, anti-glucan adhesion test on Lactobacillus acidophilus bacteria was carried by culturing the bacteria at 37ºC temperature in a jar with 10% CO2. Test tubes were placed at an angle of 30º for 18 hours to review the attachment of bacteria at the glass surfaces. After the incubation, the culture of bacteria was vibrated using a mixer vortex for a few minutes, and then cultured in solid MRS A media. Bacteria grown were measured by using colony counter. Result: The ethanol extract of propolis with a concentration of 1.56% was the lowest concentration inhibiting the attachment of glucan to Lactobacillus acidophilus bacteria. Conclusion: The ethanol extract of propolis with a concentration of 1.56% can be used as an anti-glucan material for Lactobacillus acidophilus bacteria.

Abstract

Background: The success of endodontic treatment can be achieved when pathogenic bacteria are eliminated from the root canal and periapical tissue resulting in healing of such tissue. One of the bacteria located in root canals is Staphylococcus aureus (S. aureus) reportedly found to be in severe periapical abscesses. Photodynamic therapy is one current technology that can help eliminate microorganisms without causing damage to human body cells. Average of research has been conducted using different tools and bacteria to evaluate the effects of exposure time used in photodynamic therapy on the number of bacteria. Purpose: The research reported here aimed to determine the correlation between the exposure time of photodynamic therapy and the number of S. aureus bacteria. Methods: The S. aureus bacteria used in this research were divided into seven treatment groups: a control group and six treatment groups with respective exposure times of 10, 20, 30, 40, 50 and 60 seconds. All of the bacteria were administered a photosensitiser and radiated according to the treatment intended for each group. They were then planted in nutrient agar and incubated for 48 hours. The colonies of bacteria formed were calculated using the Quebec colony counter and subsequently analyzed by means of both Kruskal Wallis and Mann Whitney U tests. Results: After calculating the number of bacterial colonies, the average number of Staphylococcus aureus bacteria in the non-irradiated group was 119 CFU/ml, 29 CFU/ml in the group with a 10-second exposure time, 20 CFU/ml in the group with a 20-second exposure time, 13 CFU/ml in the group with a 30-second exposure time, 7 CFU/ml in the group with a 40-second exposure time, but none in the groups with exposure times of 50 or 60 seconds. Conclusion: The longer the photodynamic therapy exposure time, the greater the number of S. aureus bacteria eliminated. An exposure time of 50 seconds was found to be sufficient to exterminate all S. aureus bacteria present.

Abstract

Background: Damage to porcelain restorations such as fractures requires a repair that can be performed either directly or indirectly. Direct repair involves directly performing restoration of fractured porcelain with a composite resin application. This technique has more advantages than indirect repair because it requires no laboratory work and can be completed during a single visit. Silane, on the other hand, has been widely used and is reported to increase porcelain and composite resin attachments during the direct repair process. Purpose: This study aimed to determine the differences in shear bond strength between porcelain and composite resin during the administering of 4% and 19.81% silane. Methods: 27 porcelain samples were divided into three groups, namely: Group A - 4% silane, Group B - 19.81% silane and Group C - no silane, prior to the application of composite resin. Each sample was tested for shear bond strength by means of Autograph and fracture analysis performed through stereomicroscope and scanning electron microscope tests. Data analysis was subsequently performed using an ANOVA test. Results: There was a significant difference between the three groups with p=0.000 (p<0.005). The lowest bond strength was found in the group without silane, while the highest was in the group with 4% silane (p<0.005). Conclusion: The use of 4% silane can produce the highest shear bond strength of porcelain and resin composite.

Abstract

Background: One purpose of operative dentistry is the maintenance of healthy pulp by reducing the need for root canal treatment and the possibility of undesirable scenarios such as tooth loss. Propolis is a plant-derived substance that contains a resin produced by honeybees belonging to the Apis mellifera species. Purpose: This study aimed to investigate the effect of a combination of calcium hydroxide (Ca(OH)2) and propolis extract on odontoblast-like cell proliferation in Wistar rats (Rattus norvegicus). Methods: This research constituted a true experimental laboratory-based investigation with post-test control group design. Thirty Wistar rats were randomly divided into six groups. The first molar pulp of each sample was perforated on occlusal surfaces using a low speed round bur. On day 3, the samples were divided into six groups (n=10): Group I: control; Group II: Ca(OH)2 + 11%; propolis extract; Group III: Ca(OH)2 + aquadest, and on day 7: Group IV: control; Group V: Ca(OH)2 + 11% propolis extract; Group VI: Ca(OH)2 + aquadest. All samples were filled with restorative material. They were subsequently sacrificed after 3 and 7 days post-pulp capping administration and the afflicted tooth extracted for hematoxylin and eosin (H&E) staining. The resulting data was subjected to statistical analysis to ascertain the proliferation of odontoblast-like cells. The significance of differences between the groups was determined by a one-way ANOVA test followed by a post hoc Tuckey HSD. A p-value <0.05 was considered to be significant. Results: On day 3, a significant difference existed between group II (Ca(OH)2–propolis) and group I (control group) and group III (Ca(OH)2–aquades), whereas Ca(OH)2–propolis revealed that the proliferation of odontoblast-like cells was higher. Meanwhile, on day 7, there was a significant difference between all groups whereas, with regard to Ca(OH)2–propolis, the proliferation of odontoblast-like cells in group V was higher. Conclusion: Application of combination of Ca(OH)2-propolis extract can increase the proliferation of odontoblast-like cells in pulp tissue on days 3 and 7.

Abstract

Background: The prevalence of dental caries is high worldwide and specifically in Indonesia, especially in children. Cariogenic bacteria are the major cause of dental caries. Streptococcus mutans (S. mutans) is one of the bacteria often associated with caries, due to its ability in producing acid and forming the biofilm for bacterial colonisation on the surface of oral cavities. In addition to S. mutans, Streptococcus sobrinus (S. sobrinus) bacteria are also thought to play an important role in the process of caries. Purpose: This study aims to analyse the distribution of S. mutans and S. sobrinus in children with seriously high dental caries levels. Methods: This study was an observational analytical study. Bacterial isolation was conducted in carious lesions of 50 paediatric patients 6-12 years old with superficial dental caries. Samples of caries lesions were put directly into a tube containing the Brain Heart Infusion Broth (BHI-B) and incubated at 37o C for 24 hours. The samples were sub-cultured on selective tryptone yeast cystine sucrose bacitracin (TYCSBHimedia) agar, and then incubated for two days. Bacterial identification was then performed using the polymerase chain reaction (PCR) Multiplex method. Statistical analysis with Chi-square. Results: The total number of children with dental caries included in this study was 50. Among these, 94% showed positive for S. mutans and 30% positive for S. sobrinus. The analysis of the prevalence of bacterial colonisation (S. mutans and S. sobrinus) based on caries severity and the Simplified Oral Hygiene Index (OHI-S), showed there was no significant difference (p> 0.05). Conclusion: This study showed that among 50 caries noted in the children, 94% were colonised S. mutans and 30% S. sobrinus. There was no significant difference between the colonisation of S. mutans and S. sobrinus among children from the severe to mild decayed exfoliated filling teeth (DEFT) category, and between bad and good OHI-S.
