Abstract

Introduction: Acrylic resin is the most common material for the denture base because acrylic resin has good esthetics, ease of processing, reparability and inexpensive. A disadvantage of acrylic resin is that it is easily to be cracked. One of the ways to resolve this problem is by adding the agave sisalana fiber and E-glass fiber. The purpose of this study was to find out the effect after addition agave sisalana fiber and E-glass fiber on impact strength of an acrylic resin denture plate reparation. Material and Method: The experiment involved twenty seven plates of heat-cured acrylic with the dimensions of 55x 10 x 10 mm with the 26 x 5 x 4 mm for the cavity to measure, each measurement divided into three groups, with nine samples for each groups. The first group as a control group (without fiber), the second group as a group with agave sisalana fiber addition, the thirdgroup as a group with e-glass fiber addition. All plates were soaked in distillation water for one day at 37oC. Plates were tested for impact strength using the charpy method. All data obtained was analyzed with one-wayANOVA followed by LSD (Least Significant Difference) with p<0,05. Result and Discussion: The result showed that the influences of impact strength between without fiber with agave sisalana fiber and E-glass fiber addition on acrylic denture reparation. Acrylic denture reparation in both fibers with concentration 3,3%, agave sisalana fiber has the highest impact strength rather than e-glass fiber. Conclusion: The conclusion of this study is that there is an increase in impact strength with agave sisalana fiber and E-glass fiber addition on acrylic denture reparation and agave sisalana fiber has the highest impact strength.

Abstract

ABSTRACT Heat cured acrylic resin is the most commonly used material in making denture bases. Acrylic resin is in contact with saliva, drinks and food so that the denture is a place for the formation of plaque and an increase in microorganisms, namely the fungus Candida albicans and Staphylococcus aureus bacteria, which can cause Denture stomatitis. Papaya leaf extract containing flavonoids, saponins, tannins and alkaloids can act as anti-bacteria. The purpose of this study was to determine the effectiveness of papaya leaf extract (Carica papaya L.) on the amount of growth of Staphylococcus aureus on a heat cured acrylic resin denture plate. The study was post test only with control group design. Samples were contaminated with Staphylococcus aureus suspension and incubated, then inserted into a test tube, then immersed for 3 minutes, then inserted into Saboroud's broth and continued with calculation of the number of colonies. Data analyzed with One Way Anova difference test obtained a value of p <0.05, which mean that the number of Staphylococcus aureus colonies between treatment groups and control groups had a significant difference. The LSD test found a significant difference (ρ <0.05) between aquades and papaya leaf extract 2.5%, 5%, 10% and fittydent®. Whereas at 10% concentration when compared with fittydent® there was no significant difference (ρ> 0.05). From the results of the study it can be concluded that immersing heat cured acrylic resin plate in papaya leaf extract can inhibit Staphylococcus aureus growth, according to the increase in concentration where the most effective concentration was 10%.

Abstract

Introduction: Fiber Reinforced Composite (FRC) post is one of the choices in post root canal treatment. Resin cement polymerization results in shrinkage, creating micro gaps between the FRC posts and the root canal wall. This study aimed to find microleakage differences of prefabricated FRC posts with different root canal diameters. Methods: Twenty four maxillary central incisors were used, the root length was 13 mm from the apex. The root canal was prepared with conventional technique and then filled with a single cone technique. Samples were divided into 4 treatment groups of 1.2 mm, 1.4 mm, 1.6 mm and 1.8 mm diameter, cemented, then coated with sticky wax and nail polish and immersed in 2% methylene blue liquid and put into an incubator at 37o for 72 hours. Objects were divided into two mesiodistal directions, observed under a 20x-magnification stereomicroscope. Results: Kruskal-Wallis test showed significant differences in all treatment groups (p <0.05). Mann-Whitney test showed differences between groups (p<0.05) of Ø 1.2 mm and Ø 1.6 mm, Ø 1.2 mm and Ø 1.8 mm, and Ø 1.4 mm and Ø 1.8 mm group. Discussion: The main cause of microleakage at the edge of restoration is because the resin cannot completely close the edges, resulting in shrinkage and contraction during polymerization of the composite resin. Conclusion: There were microleakage in the four groups, the wider root canal might lead to greater microleakage. Keyword?Microleakage, FRC, root canal diameters.

Abstract

Heat cured acrylic resin is a dental material that widely used as removable denture base due to its biocompatible, easy to obtain, inexpensive and ease of processing but has a disadvantage of being fracture. The purpose of this study was to determine the diffe-ference in the impact strength test of the HCAR after adding pineapple leaf fibre. Post-test only control groups design was used as laboratory experimental. This research divided into 4 groups, those are without addition pineapple leaf fibres, addition of 5%, 10%, 15% pineapple leaf fibres. Impact strength was performed by charphy impact test. After getting the mean results of the im-pact test, the Kruskal Wallis test was then performed that showed that there is a significant difference between the group without addition pineapple leaf fibre and the group with the addition of pineapple leaf fibre a significance of p-value 0.001 (p<0.05). The plate without addition of pineapple leaf fibre, has a higher impact strength than the concentration of 5%, 10% and 15%. So it can be concluded that the addition of too high concentration pineapple leaf fibre causes the impact strength of the acrylic resin decreased.
