Abstract

Nylon thermoplastic has started being used as a denture base material because it is made of a flexible material that is not easily broken and good aesthetics. However Valplast has the disadvantage that easily absorbs water so as to affect the strength of the material that may result in changes in the form of the so-called plastic deformation. Robusta coffee bean extract is a herbal ingredients that can be used as a denture cleanser, chlorogenic acid contained in robusta coffee bean extract can supposedly break the chains of thermoplastic polyamide nylon. This aims of this study determine the effect of robusta coffee bean extract of the plastic deformation of thermoplastic nylon. This research is to design laboratory experimental post -test only control group design. The sample size of 64x10x2,5 mm totaling 24 samples. Samples were divided into 6 groups immersed in robusta coffee bean extract, sodium perborate and sterile distilled water for 4 days and 19 days. Plastic deformation of thermoplastic nylon plate was measured by using a Universal Testing Machine, by way of test equipment built at the sample with a second buffer distance of 50 mm, then the machine is switched on and the weight will drop right tools in the middle of the plate. One Way Annova test results showed that there were 0,000 significant difference between each group (p<0.05). The conclusion of this study is there are significant between the thermoplastic nylon plates after immersion with robusta coffee bean extract to deformation plastic. Keywords : Plastic deformation, robusta coffee been extract, thermoplastic nylon.

Abstract

Background: The acidic salivary pH cause potentially undergo orthodontic wire constituentmetal ions release. The release of metal ions can affect the quality of orthodontic wire.Objective: To analyze the effect of immersion thermal NiTi archwire in the bottled tea drinks tothe archwire force deflection. Material and Methods: The sample size were 12 round thermalNiTi orthodontic archwires (3M; 0,016 inch) which divided into three groups: a control group(artificial saliva), a group of bottled tea drinks and bottled tea drinks of fruit flavors. The sampleswere immersed in an incubator for 10.5 hours at 37 ° C. The deflection test used Three-PointBending method with a Universal Testing Machine in each group. Results and Conclusion:The results of One Way ANOVA test obtained value of 0.768 (p>0.05) which indicates that nosignificant difference in each group. The conclusion from this study is the bottled tea drinks cannot affect the force deflection of thermal NiTi orthodontic archwires.Keywords: Bottled tea drinks, Force deflection, NiTi thermal archwire

Abstract

Alginate is an impression matter that often used on dentistry. Some studies showed that aginate caused cross infection. it needs a disinfection product to avoid that cross infection. the disinfection matter which often used are betel pepper leaf boiling water and the sodium hypochlorite, but alginate have imbibition characteristic and fenol that contain in betel pepper leaf boiling water suggested dimensional changes on alginate. The technique of this research with sprayed technique. The aim of this research’s to find dimentional stability on casts made from alginateafter disinfection procedure with sprayed technique used 35 % betel pepper leaf boiling water and 0,5 % sodium hypochlorite. This research is an experimental laboratories using post test only control group design. The samples are an upper jaw replica. The samples are 28 samples and divided into 4 groups. A group is directly filling and the others are sprayed with aquadest sterile, 35 % betel pepper leaf boiling water and 0,5 % sodium hypochlorite and saved in vacuum box for 10 minutes. Samples measured by term mizzen with 0,05 accuracy.The conclusion of this research is there was dimentional changes on casts made from alginate after disinfection procedure with sprayed technique used 35 % betel pepper leaf boiling water and 0,5 % sodium hypochlorite.  Keywords: Alginate, betel pepper leaf, cross infection, dimensional stability, sodium hypochlorite.

Abstract

A Impression material that is often used is alginate. Alginate has Characters imbibition and syneresis properties that can cause dimensional changes alginate mold result. Another factor to consider is the control of transmission of infection from alginate, as alginate mold result became one of the agents of transmission of infection in the dentist, it is important to take action disinfection with a disinfectant solution. Type of laboratory experimental research with the study design The Post Test Control Group Design on 72 samples of alginate mold. Sample grouping consists of 9 groups , 1 control group and 8 treatment groups with soak and spray technique using a disinfectant solution for 10 minutes. In each treatment group dimensional stability changes, except the control group because the treatment is not used. Technique that gives greater influence on changes in dimensional stability is the soaking technique. But the use of a variety of different disinfectant solution did not impact on the mold result. There are significant differences in the dimensional stability of the disinfection technique. Techniques greater dimensional stability is changing soaking technique. But the use of various disinfectant materials do not have a significant effect on the dimensional stability of alginate mold result. Recommended spraying disinfection action and further research needs to done on alginate. Keywords: Alginate, Dimensional Stability, Infection Control

Abstract

Background: Coffee has a by-product (waste product) that generated from coffee processing. Coffee fruit's peels contains active compound, that is pectin. Pectin has several benefits in health, as a regeneration of hard and soft tissue that can be applied in dentistry and pectin has the potential as an anti-cancer substance. Pectin as a biomaterial must have biocompability. Biocompatibility of the material can be tested by cytotoxicity test by MTT method on human dental pulp fibroblasts cell culture. Objective: To know the toxicity of extract pectin from coffee robusta fruit peels on human dental pulp fibroblasts cell culture. Method: This research is a experimental laboratory with post-test only control group design. Culture of fibroblast cells at the well was exposed by pectin extract for 24 hours, then each well was given MTT and incubated for 4 hours. The effects of cytotoxicity were measured by calculating cell viability (%). Data were analyzed using Probit test, One-way ANOVA followed by LSD. Result: Each group has a cell viability value above 50%. Conclusion: Extract pectin from Robusta coffee fruit peel's had no cytotoxic effect on human dental pulp fibroblsts cell culture Keywords: coffe robusta fruit peels, cytotoxicity, human pulp fibroblst cell culture, pectin
