Abstract

Background: Orthodontic bracket is one of the components in a fixed orthodontic treatment. The influence of the oral cavity of an orthodontic bracket is a type IV hypersensitivity reaction due to corrosion on the bracket. The solution of extracts of betel leaf (Piper betle L.) of 50% which could affect corrosion. This study aimed to know the effect of betel leaf extract solution (piper betle L.) 50% against metal ion release.Method: The research method was “The Post Test Control Group Desain”, consists of four large groups respectively soaked with 6 units of brackets, consisting of a solution of betel leaf extract (piper betle L.) 50% (treatment), aquabidest (negative control), artificial saliva (negative control) and Naf (positive control) incubated for 7 days with a temperature of 370 C. Then ion measurement using the tool inductively coupled plasma – optical emission spectrophotometry (ICP-OES).Results: this study showed that the average release of ion the largest was on the solution of betel leaf extract (0.157167) then aquabides (0.086967), artificial saliva (0,08833) and sodium flouride (0.005533). Test results of Mann-Withney showed the presence of significant difference (p<0.05) release of ion Ni, Cr and Fe on four groups except among artificial saliva groups and sodium fluoride but the group that was soaked in a solution of betel leaf extract (piper betle L.) 50% occured a release of ion Ni, Cr and Fe higher. This is because the samples werestored in solution of betel leaf extract (Piper betle L.) of 50% which is a liquid electrolyte that can cause ion release.Conclusion: Betel leaf extract (piper betle L.) 50% is not effective to be used as an alternative to slow corrosive to metal ion (Ni, Cr and Fe) on a metal bracket.

Abstract

Background: Bioflm begins with formation of pelicle and within a minutes the colonization of bacteria attached to surface of the teeth. One of early bacteria attached was Streptococcus mutans. This study used 25% beluntas leaf extract in influencing the growth of Streptococcus mutans bioflm. The purpose of study was to investigated effect of 25% beluntas leaf extract on Streptococcus mutans bioflm.Methods: This research was experimental laboratory with post test only control design, consist of four treatment groups, 25% beluntas leaf extract and 0.12% chlorhexidine incubated 24 hours and 48 hours. Bioflm formation was measured by calculating Optical Density using a spectrophotometer. Data analysis was performed using One Way Anova test followed by Post Hoc LSD test.Result: The results showed that beluntas leaf extract could influence theformation of S.mutans bioflm but the effect in inhibiting bioflm formation is still not as good as chlorhexidine. It is known from the results of One Way Anova 25% beluntas leaf extract and 0.12% chlorhexidine incubated for 24 hours and 48 hours showed signifcant difference (p <0.05).Conclusion: The conclusion of this research is the effect of beluntas leaf extract (Pluchea indica (L.) Less) 25% to Streptococcus mutans bioflm in vitro.

Abstract

Background: Glass ionomer cement (GICs) has become a common restorative material in dental practice. Therefore, there are so many GIC's brands can be found in the market with tremendous price disparities GIC brands can be found in the market with huge price disparity; Price of one brand can be up to tenfold than the others. For the cost-efficiency reason, many clinicians prefer the more economical. Therefore, questions arise from the clinician, does it influence the clinical performance. Method: Six cylindrical specimens (10mm x 2mm) from four GIC brands (Fuji IX, FXUltra, GlassyCem and Sangchi) were made based on the respective factory instructions and stored for 24 hours until the final setting reached. Micro Vickers hardness tester (Shimadzu) and Surface roughness tester were used as surface characterizations measurement. Collected data were analyzed statistically. Results: Kruskal-Wallis and Mann-Whitney analysis showed that Fuji IX and FXUltra significantly (p<0.05) higher surface hardness (68.47 and 63.29 VHN respectively) compared to GlassyCem and Sangchi (38.53 and 36.70 VHN). While for surface roughness measurement, Fuji IX has the highest surface roughness, 7.22 µm (p<0.05). GIC’s clinical performance is affected by composition and powder-liquid ratio. Strontium in Fuji IX could increase surface hardness. The high powder-liquid ratio in Fuji IX and FXUltra improve its clinical performance compared to the other group. Conclusion: The more expensive GIC (Fuji IX and FX ultra) had better surface hardness with a slight difference in surface roughness. Therefore, clinicians should choose GIC based on cost-efficiency without ignoring clinical performance.

Abstract

Background: Heat-cured acrylic resin is a material that is often used for the manufacture of removable partial dentures in dentistry because it uses simple equipment, relatively inexpensive, and is easy to repair. Acrylic resin also has a disadvantage, such as the low value of flexural strength so that it can cause the denture to fracture. This study determine the effect of non-dental glass fiber volume fraction on the flexural strength of heat cured acrylic resin.Method: This research are post-test only control group design. Acrylic resins were divided into four groups (6 sample each group), group 1 without the addition of non-dental glass fiber or 0% and heat cured acrylic resin group with the addition of non-dental glass fiber 1%,2%, and 3% (group 2, 3 and 4).Result: The average flexural strength of acrylic resin with a volume fraction of 2% of non-dental glass fiber had the highest value compared to other groups. The results of the Mann-Whitney test from several test groups showed significant differences in the value of flexural strength from each group (p<0.05), except for the 0% and 3% group.Conclusion: There is an effect of volume fraction of non-dental glass fiber on the flexural strength of heat cured acrylic resin.

Abstract

Background: Composite resin is one of the most used materials in dentistry because of the simplicity and high aesthetic value. One of the varieties of composite resin is prepolymerized composite resin. Some research show that prepolymerized composite resin has relatively low mechanical strength. Therefore fiber needs to be added in prepolymerized composite resin. The aim of this research is to find out the effect of adding non dental glass fiber into tensile strength fiber reinforced composite. Method: This research used true experimental method with post test only control group design, there are two groups, the first one is prepolymerized composite resin with additional non dental glass fiber. The data has been tested with parametric independent T-test. Result: The result showed the average flexural strength of prepolymerized composite resin without additional non dental glass fiber was 10.6625 Mpa, while the prepolymerized composite resin + non dental glass fiber was also 18.2263 Mpa. Independent T-test showed the p value = 0.000 Conclusion: The conclusion of this research is that prepolymerized resin + non dental glass fiber has higher tensile strength than composite resin without additional non dental glass fiber, thus it can be used as alternative choice applied in dentistry.
