Abstract

Microleakage is one of the major problems in the successful of a composite resin restoration. The application of coating materials using surface sealant or re-bonding using bonding agent to the surface of the restoration is a method to reduce the occurrence of microleakage. The aim of this study is to determine the differences in microleakage between the application of surface sealant and one-step self-etch adhesive after composite resin restoration on class V cavities. Twenty-one lower premolar teeth were randomly selected and then divided into two treatment groups that consist ten samples for each group and one sample as control. Group I: Surface sealant (G-Coat Plus), group II: One-step self-adhesive (OptiBondTM All-In-OneTM Kerr), and the control group was not given any coating materials. All samples were prepared in the buccal surface with a size of 3 mm occlusal-gingival, 3 mm mesial-distal, and 1.5 mm cavity depth. After applied coating materials for all treatment groups, all samples including control group are smeared with nail coloring on the crown and apex, except the surface of the restoration until 1 mm around the restoration. Samples were then immersed in artificial saliva for 24 hours, followed by immersion in methylene blue for the next 24 hours. The teeth are cut in a buccal-lingual direction and then observed the penetration depth of methylene blue under a stereo microscope using 20x magnification. Statistical analysis using Mann-Whitney test between two treatment groups (p<0.05). The results of this study indicate that group I has less microleakage than group II. The conclusion of this study is that there are differences in microleakage between the application of surface sealants and one-step self-etch adhesive after composite resin restoration on class V cavities.

Abstract

Alginate is an impression material that is widely used in dentistry but lacks dimensional stability. The time delay for filling in the gypsum is also one of the things that causes a change in the dimensional stability. Natural starch can be found in plants, one of which is rice, which is often found. Starch and alginate can both undergo a gelatinization process so that starch can be used as an alginate mixture. This study aims to determine the effect of adding rice starch to the alginate printing material and the time delay for filling the gypsum on the dimensional stability of the printed output. This research wass a laboratory experimental study using a post-test only control group design. The sample of this study consisted of 36 samples divided into 12 groups. Measurement of the dimensional stability of the printed output was carried out using a digital caliper. The data were analyzed by means of the Two-Way ANOVA test. The results showed that the mean percentage change in the dimensions of the treatment group was smaller than the control group. The results of the Two-Way ANOVA test showed significant results (p <0.05) on the effect of the concentration of rice starch in the alginate printing material on the dimensional stability of the printouts, while the effect of the time delay for filling the gypsum on the dimensional stability of the printed results showed insignificant results (p>0,05). There was an interaction between the concentration of rice starch added and the time delay for filling the gypsum on the dimensional stability of the printouts (p <0.05).

Abstract

Teeth discoloration has been complained by most of Indonesians. A treatment of teeth discoloration can be overcome by using a bleaching treatment. Bleaching itself, can be done using a natural ingredients, for instance avocado (Persea americana Mill.),which contained an ascorbic acid for a dental bleaching. The aim of this study is to find out the effectiveness of avocado with concentrations of 30%, 70%, and 100% on a teeth bleaching. It is a laboratory experimental research using a pretest-posttest control group design. The sample used are 24 post-extraction of premolar teeth, and ascorbic acid which was taken from the avocado by an isolation method. The teeth soaked in a black tea for 6 days and replaced every 2 days, then soaked with ascorbic acid in the avocado extract 30%, 70%, 100%, and control aquades for 3 days.The degree of teeth color was measured by using a spectrophotometer. The data analysis used a discrimination test with One Way Anova and further discrimination test with Pos Hoc Anova. The results of discrimination test with One Way Anova showed the significant value was 0,019 (p<0,05), which means there was difference colour between before and after the soaking teeth treatment using the ascorbic acid in avocado with concentrations of 30%, 70%, and 100%. Based on Pos Hoc Anova test, showed that 30% and 100% concentrations of ascorbic acid is more effective than the aquades. As the 100% concentration of ascorbic acid showed a demineralization. Therefore the 30% concentration of ascorbic acid is the most effective. The ascorbic acid in avocado extract (Persea americana Mill.) with 30%, 70%, dan 100% concentrations is effective for a dental bleaching.

Abstract

Carbonated soft drinks (soda) are often consumed by the world community including Indonesia by all people, both young and old. The high sugar content in soft drinks can increase blood sugar if consumed continuously. In addition, soft drinks with artificial sugar have a higher acidity than regular sugar. With such a high level of acidity and continuous consumption, tooth surface roughness can decrease. One of the most frequently used restorative materials in Indonesia is Glass Ionomer Cement (GIC) because it is easy to manipulate and binds directly to enamel and dentin. The purpose of this study was to determine the effect of consuming soft drinks with artificial sugar on GIC restoration materials. Thirty GIC specimens with a diameter of 6 x 2 mm were immersed in mineral water and Diet Coke for 24 hours. Before and after immersion, the specimens were examined with a surface hardness test, scanning electron microscope and analytical scales. Data analysis used paired t test and kruskall wallis. From the paired t-test statistical test, there was a significant difference between the percentage reduction in weight of the GIC sample after immersion in water with Diet Coke. The Kruskal Wallis test results showed that there was a significant difference in the roughness value of GIC immersed in mineral water with Diet Coke. The pH of carbonated drinks with artificial sugar (Diet Coke) below the critical pH (5.5) can affect the solubility of the GIC specimens, thereby giving changes in surface roughness, changes in weight and changes in surface morphology of GIC specimens.

Abstract

Dental composite defined as a combination of two or more different materials with superior properties possessed, thus resulting in better properties than the original material, which hardened through the polymerization process. This restorative material is widely used because it has a higher aesthetic value compared to other dental filling materials. The evolution of composite resins in dentistry has occurred since they were first introduced as dental restorative materials, until now, the development of materials continues to increase significantly, especially in their aesthetic value. A good aesthetics material will greatly affect the results of the treatment in clinical applications.

Abstract

The surgical sutures is one of the main techniques used for wound closure. In the oral cavity, suture are often used after procedures such as tooth extraction, implant surgery, and various oral and periodontal treatment procedures. The purpose of this article is to provide knowledge to readers, especially dentists and academics regarding the function of sutures, general characteristics, as well as various materials of sutures. Suture which are used in dentistry are different from suture used in other areas of the body due to saliva, high vascularity, and other functions in oral cavity such as, speaking, chewing and swallowing. The ideal surgical suture depends on the type of surgery, the location of the wound, and the general condition of the patient. Suture threads that do not match the conditions of the surgical wound and the patient's condition will prolong the healing process and can cause infection. By improving the knowledge about surgical suture, dentists are expected to be able to choose the most appropriate surgical suture based on the patient's condition. In academic terms, by knowing the various choices of surgical suture materials, academics are expected to be able to know the advantages and disadvantages of the sutures which can also inspire them to improve the quality of existing sutures.

Abstract

Fiber reinforced composite (FRC) is widely used to replace porcelain fused to metal (PFM) for patients who have lost teeth. Fiber reinforced composite is resin matrix protheses with fiber reinforced to get optimal strength. Glass fiber dental is often used because it does not require complex preparations, not sensitive to chemicals and moisture, but it has an expensive price for Indonesian people and limited availability. An alternative material such as glass fiber non dental can used. Mouthwash is used as an antiseptic and anti-plaque material on the oral cavity. Mouthwah can affect of water sorption of FRC. The aim of this study is to know effect of mouthwash on the absorption of water in non dental glass fiber - reinforced FRC. Sixty specimens divided into four groups (n=4), 2 groups with glass fiber dental soaked on the bisguanida and aquades, 2 groups with glass fiber non dental soaked on the bisguanida and quaternary ammonium. The data analyzed with Anova. Anova test showed that there is an influence of mouthwash bisguanide and quartenary ammonium compounds on the value of absorption of glass fiber reinforced composite water (p<0,05). Water sorption of FRC in bisguanide mouthwash is higher than quartenary ammonium compounds.

Abstract

Composite resin is the material most often used as a restorative material. Acid etching is one of the procedures to help provide a place for penetration of bonding materials and composite resins. The acidic etching material that is often used is 37% phosphoric acid, but 37% phosphoric acid can cause inflammatory cell infiltration. Tartaric acid composed of weak acids that has potential to be an alternative acid etching. The aim of this study is to determine whether there are differences in microleakage of nanohybrid composites after application of tartaric acid etching between concentrations of 10%, 35%, and 40% in prevention of microleakage. This research is a laboratory experimental research with a posttest-only group design. Research samples are 24 maxillary first premolar were divided in 4 groups. Group I with 10% tartaric acid, group II with 35% tartaric acid, group III with 40% tartaric acid and group IV with 37% phosphoric acid etching. Based on the results of the LSD test it shows that There is microleakage of nanohybrid composites after etching application of tartaric acid concentrations of 10%, 35%, 40%, and 37% phosphate in class I cavities. Tartaric acid concentration of 40% can be used as an alternative to etching 37% phosphoric acid in preventing microleakage.
