Abstract

Tea is the most popular beverage product that is consumed by many people in Indonesia and the world community because tea has a distinctive taste and aroma. Tea contains a rich source of polyphenols (catechins) which are part of flavonoids that can inhibit the growth of Streptococcus mutans, Streptococcus sobrinus and Lactobacillus which are bacteria that cause dental plaque formation. Purpose, to analyze the effectiveness of white tea (camellia sinensis L.) gargling on the dental plaque index. Method, quasi experiment with pre and posttest control group design. This research was conducted at the Faculty of Dentistry, University of Muhammadiyah Semarang with a total of 36 samples taken by random sampling technique. The treatment group (white tea) and the control group (0.2% chlorhexidine) were calculated using the PHP-M plaque index. The value of plaque index before gargling in white tea steeping had an average value of 1.77 ± 0.60 and the value of the plaque index after gargling in steeping white tea had an average value of 1.18 ± 0.48. The results of the statistical analysis dependent test t test showed p = 0,000 (p<0.005) so that there were significant differences between the plaque indices in the white tea group before and after treatment. The results of the independent statistical t test showed that the chlorhexidiene control group was 0.2% p = 0.024 (p<0.005) and white tea p = 0.003 (p<0.005). It was concluded that white tea was more effective than chlorhexidine 0.2%. Conclusion, Gargling of white tea steeping is effective in decreasing dental plaque index.

Abstract

Early Childhood Caries (ECC) is a form of dental caries that occur rapidly. ECC is a common chronic disease in children that could harm self-esteem, nutrition, oral cavity development, also quality of life, then veer to malocclusions and psychological problems. In children with severe early childhood caries (SECC), losing vertical dimension of occlusion were also reported to occur 2.5 times more. Restoration of deciduous teeth with severe damage offers great challenge for pediatric dentists. This case reported clinical management of patients suffering from SECC using stainless steel crown to restore masticatory function and vertical dimensions. A 5-year-old boy escorted by his parents came to pedodontic dentistry Clinic at Universitas Padjadjaran Dental and Oral Hospital, with complaints of many tooth were damage. On clinical examination, it was shown that all primary teeth have caries, except for the two mandibular lateral incisor, teeth 16 and 26 were partial eruption, with deep bite in the anterior region. Therefore the diagnosis was deep bite in the anterior region because of SECC. Correction then had done by modifying metal crown restorations on posterior teeth. Modification of stainless steel crown restoration can correct vertical dimension of occlusion so as to prevent malocclusion.

Abstract

Case of bone destruction such as socket of post-tooth extraction and periodontitis can cause pain and disrupt the function of mastication, so it takes a tissue engineering material in the form of biomimetic scaffold by mimicking the structure and the original function of bone. Material for bone tissue engineering that has grown widely include the use of collagen, gelatin, chitosan, and hydroxyapatite. These materials can be mutually combined using crosslink agents in the scaffold fabrication process. Determine the role of crosslink agents in the manufacture of biomimetic scaffolds as bone tissue engineering materials in the field of dentistry. Material in the scaffold fabrication is a polymer which can be modified by the incorporation of other polymers. Additionally, polysaccharides have abundant functional groups such as hydroxyl groups, amino groups and/or carboxylic acid groups, amenable to various types of chemical modifications. Modification with other polymers can be done by adding crosslink agents by irradiation or through chemical reactions. The role of a crosslink agent in a material modification can increase the material resistance to heat, light, other physical properties, and can increase the degree of dimensional stability and mechanical strength so these values are important to consider for the survival of cells in scaffolds at early time points. Different forms of crosslink agents can be utilized to obtain good biomimetic scaffold so that optimize the osteoconductivity properties of bone tissue engineering.

Abstract

CoCr has high mechanical properties but may release ion in an acidic environment as in the oral cavity. Cobalt (Co) ion can release from CoCr alloy if such material is immersed in acidic environment. This situation may lead to several consequences including allergies and oral lesions. The aim of this research was to determine the influence of pH degree on acidic saliva to the Co ion release concentration of CoCr L605 alloy. This research used CoCr L605 alloy and artificial saliva. Twelve samples of CoCr L605 metal plates were made into (10x10x1.5) mm size. The samples were divided into three groups; each group immersed in 20 ml of artificial saliva for 14 days, 37o C. The pH variables for the groups are 3, 5 and 7. Co ion released was measured by Atomic Absorption Spectroscopy (AAS). Data analysis was performed by one-way ANOVA (Analysis of Variance). The result showed that the mean of concentration value of Co ion released for group pH of 3, 5 and 7 were (3.0970±0.612)ppm; (2.0250±0.609) ppm; and 0.000 ppm respectively. One-way ANOVA showed that pH degree of acidic saliva significantly influenced by the Co ion release concentration (p<0.05). LSD test showed a significant difference between groups. The conclusion of this research was the less pH degree of saliva, the concentration of Co ion released of CoCr L605 alloy was higher.

Abstract

One of the restorative dental materials that is continuously developed is Glass Ionomer Cement (GIC). The aim of this research is to know whether there is influence of nanofilled resin coating application on GIC to reduce surface roughness. In this study GIC type II (EQUIA Forte, GC, Japan) was used to be mechanically manipulated and inserted into a mold which produced a sample of 6.0±0.3 mm in diameter and 3.0±0.2 mm in height. GIC samples were divided into 2 groups namely 10 GIC samples were not coated with nanofilled resin coating as control group and 10 GIC samples were coated with nanofilled resin coating as treatment group. GIC samples were tested immediately and then immersed in sterile distilled water in a 37°C incubator. After 24 hours, GIC samples were surface roughness tested using a Surface Roughness Tester. Then all samples were brushed using a soft bristle mechanical tooth brush for 1 hour. After brushing, the sample is tested for final surface roughness. The results showed an increase in surface roughness in non-coated group/control (0.005 ± 0,328mm) and coated group (0.015±0.240 mm). Statistical data analysis using unpaired t test showed that there was no significant difference (p>0.05) in the increasing of surface roughness between control group and treatment group. It can be concluded that application of nanofilled resin coating to GIC cannot reduce the roughness of GIC surface.

Abstract

Acrylic resins are widely used as removable denture baseplate. These resins need adequate cleaning and maintenance. One way to clean resin denture is by immersing it in a denture cleanser solution. Denture cleanser should have antibacterial and antifungal properties. Chitosan is a natural antibacterial and antifungal substance. Unfortunately, acetic acid used as solvent for chitosan solvent can cause toxicity to cells. Ascorbic acid can be used as an alternative solvent for chitosan with lower toxicity than acetic acid. The aim of this study is to test antibacterial and antifungal activity of chitosan solution in ascorbic acid for the use as resin acrylic cleanser. In this study we evaluate antibacterial and antifungal activity of chitosan solution in ascorbic acid as denture cleanser solution. Acrylic resin plates were contaminated with Streptococcus mutans and Candida albicans colonies and then were immersed in five different groups of solutions, aquadest as control group, ascorbic acid, 1%, 2%, and 3% chitosan solution in ascorbic acid. Antibacterial and antifungal activity test were examined by using diffusion method (Kirby-bauer). The results were analysed using statistical analysis.Antibacterial and antifungal activity test results show that the highest significant influence was observed in 1% chitosan group, showing 1,21x104 cfu/ml for Streptococcus mutans colonies and 4083 cfu/ml for Candida albicans colonies. The optimal percentage volume for adequate antibacterial and antifungal chitosan solution in ascorbic acid is 1%.

Abstract

Resin is widely used in dentistry these days. But synthetic resin is mostly used, because natural resin production is considered expensive in western countries. Meanwhile Indonesia has potential natural resources and one of the world’s natural resin producers. Dammar resin is one of them, there are two kinds considered the best which is mata kucing dammar resin and batu dammar resin. There are different characteristics between the two resin because they came from different tree species. This research, Difference in Softening Point of Mata Kucing Dammar Resin and Batu Dammar Resin, aims to determine the difference in the softening point of the two dammar resin so we can discover the use of dammar resin as one of the basic dental materials. Softening point test was done on 16 samples of mata kucing dammar resin and 16 samples of batu dammar resin using Ring and Ball Apparatus based on SNI 01-2900-1999. From the study results, it is obtained that the softening point of mata kucing dammar resin is 87-90°C, meanwhile batu dammar resin is 150-160°C. Softening point is the temperature which when dammar resin starts to transform into semisolid. A high softening point temperature shows that the dammar resin has long hardened because the compound chemical bond is reduced as a result of oxidation reaction. Mata Kucing dammar resin is yellowish-clear is gotten by tapping directly into the Shorea javanica tree, meanwhile the batu dammar resin which is brownish-black is gotten by collecting the fossilized sap on the ground beneath the Shorea eximia tree. Therefore, the mata kucing dammar resin has less ash and dirt content. Mata kucing dammar resin and batu dammar resin have different softening point temperature.

Abstract

Amalgam mixing proccess should be completely homogeneous so that the amalgam toxicity is reduced. Untreated caries will result in some disadvantage, one of which is tooth loss and should be made a substitute for denture. Making artificial teeth requires a study model. The study model was made from the manufacture of gypsum that was manipulated with water. The preparation of gypsum dough should be minimal porusity in order for the study model to be strong and scratch resistant. Model study should be strong and minimal porusity. Stagnant and homogeneous stirring results in porousity. The porosity of the gypsum dough will affect its compression. Research purpose to Produce amalgam prints that have an initial set time faster and produce gypsum prints that have better compressive strokes. The study used a total sample of 28 specimens. The specimens were divided into 2 control groups and 2 treatment groups with each group consisting of 7 specimens. Manipulation of gypsum by using Vibragamator with ratio done and vibrator.
