Abstract

Nanohybrid resin composite is one of the restorative dental materials that has goodaesthetic value and smooth surface. However, resin composite can be discolored due toconsuming foods and beverages, one of which is a carbonated beverage. To determine the difference of discoloration of polished and unpolished nanohybrid resin compositeafter the immersion in carbonated beverage. An experimental laboratories research withthe post test only control group design. In the group of polished composite, polishing wasdone on one side only, while the unpolished composit group, any treatment wasn't done.The total were 32 samples, divided into 4 groups which were immersed in carbonatedbeverages and artificial saliva for 7 days. The shredded material was replaced every 24hours. The instrument used for testing the discoloration was a spectrophotometer. Datawas analyzed by parametric statistical test One-way ANOVA and LSD (Least SignificantDifferent). There were significant differences between the unpolished composite resin thatsoaked in carbonated beverages and the other groups (p <0.05). Unpolished resincomposite are prone to discolorate compared to the polished resin composite

Abstract

Lime juice contains some organic acids. It is a plant that is widely consumed by people.Organic acid content causes the lime has an acidic pH. The consumption of beverages containing excess acid may cause tooth erosion due to demineralizationonenamel surface.Demineralization happens constantly causes the loss of some enamel prismata and formamicroporosityinthe enamel. This research wasconducted to measure the depth of enamel microporosity of the teeth enamel is soaked in limejuice. Samples were maxillary first premolar teeth which were divided into two groups: control (soaked in artificial saliva)and treatment (soaked in lime juice) respectively for 5 and 10 minutes. Depth measurement of enamel microporosity wasmeasuredby using a scanning electron microscope, which showed no significant difference (α<0.05) between the depth ofthe microporosity of the enamel were soaked lemon juice for 5 minutes and 10 minutes. It was concluded that the longer thetooth enamel soaking in lime juice causes deeper microporosity.

Abstract

Objective: To investigate the effect of soaking of thermoplastic nylon (valplast) on clove flower extract (syzygium aromaticum) as a denture cleanser with different concentration 0.8%, 1%, 1.2%, 1.4%, and 1.6% to the color change of thermoplastic nylon.Material and Methods: 30 samples were divided into 6 groups. The sample size is (10x10x1) mm. The first group was immersed in sterile aquades and the other groups were immersed in clove flower extracts of 0.8%, 1%, 1.2%, 1.4%, and 1.6% for 12 days. The light intensity then measured using densitometer.Results: One way anova test results obtained value 0.174 (p>0.05) which indicates that there is no significant difference in each group.Conclusions: This study are darker discoloration of the thermoplastic nylon at a concentration of 1.6% and lower color changes occurring at a concentration of 0.8%.
