Abstract

Background: Composite resin is the most widely used restoration material. This material is composed of several materials such as polymer matrix, fller particles and silane coupling agents. As technology progresses, microhybrid, nanohybrid and packable composite resin materials are developed, with good handling and mechanical properties. As a polymer-based material, the composite resin absorbs the liquid, causing the solubility of the resin matrix. Carbonated drinks and chlorine, are acidic liquids that can cause soluble resin matrix. The aim of this paper is to compare water sorption and solubility between composite resin type microhybrid, nanohybrid, packable from different brand.Methods: This research used experimental method with sample of composite resin disk with diameter 15 mm and thickness 1 mm. The number of samples was 90 divided into 18 treatment groups, 9 group immersed in carbonated drinks and 9 group immersed in chlorine. The grouping is based on composite resin type microhybrid, nanohybrid, packable from different brand. Water sorption is measured by the sample mass difference before and after immersion then divided by the initial volume of the sample. While the solubility of the composite resin was measured by reducing the sample mass prior to submersion and afterdrying then divided by the initial volume of the sample.Result: The results showed signifcant differences in water sorption on chlorine, solubility in carbonated beverages and chlorine. Meanwhile, an insignifcant difference occurred in water sorption in carbonated beverages.Conclusion: water sorption and solubility in 3 types of composite resin with9 different product, not depend on the composite resin type but depend on the product used

Abstract

Background: Aloe vera contains active components such as antrhaquinones,saponin, glucomannans, and acemannans that have been known for its antimicrobial properties. In vitro study showed that Aloe vera extract can inhibit the growth of Streptococcus mutans. Studies reported that children with caries have high level of salivary S. mutans which is the main pathogen in dental caries. The gold standard mouthrinse for dental caries is chlorhexidine gluconate, but it has several side effects. The objective of this study was to compare the effect between Aloe vera juice and 0.06% chlorhexidine mouth rinse on salivary S. mutans in children with caries.Methods: This experimental research with pretest and post-test control group design conducted on 30 children (6-12 years old) with number of carious teeth >4. Subjects divided into 2 groups: Aloe vera juice group and 0.06% chlorhexidine group, which instructed to rinse their mouth with 10 ml stated mouthwash, twice a day, during 7-day period. Unstimulated saliva was collected at baseline and after 7 days then inoculated on mitis salivarius bacitracin agar. S. mutans were counted and expressed in CFU/ml. Data were analyzed using paired t-test and independent t-test.Result: The result showed that a significant reduction in salivary S.mutanscounts was observed with Aloe vera juice mouth rinse and 0.06% chlorhexidine (p<0.05). The mean reduction of S. mutans counts was not statistically significantly between grup (p>0.05).Conclusion: These findings suggest that Aloe vera juice can reduce salivary S. mutans in children with caries so it can be considered as alternative mouthwash to prevent caries.
