Abstract

ABSTRACT Nano-filled composite resin is a composite resin that has nano-sized fillers. This filler sizegives an aesthetic appearance to the composite resin thus resembles natural teeth. However, compositeresin has a disadvantage in its polymer matrix, which is easily degraded by acid solutions. Calamansiorange (Citrus microcarpa) is a solution that has acidic properties. The purpose of this research was todetermine the surface roughness value of nanofiller composite resin after immersed in a 50%concentration of calamansi orange (Citrus microcarpa). Ten cylindrical specimens of nano-filled compositeresin (Filtex Z350 XT 3M ESPE), with 5 mm diameter and 2 mm thickness. The specimens wereimmersed for 14 days with the provisions of 5 minutes in the juice of calamansi orange and 23 hours 55minutes in distilled water. Calamansi orange juice is replaced every day. The evaluation of surfaceroughness of specimens before and after immersion using Atomic Force Microscopy (AFM).Furthermore, the data were analyzed using paired t-test with a significant value is p 0.05. The resultsshowed an increase in the average value of surface roughness which was significant after exposure inthe calamansi orange with 50% concentration.

Abstract

Microleakage is a poor marginal adaptation of the restoration, often found between cavity and restoration material. One of the reasons is the shrinkage during the composite resin during polymerization, causing the restorations adaption disturbed. Application of adhesive material on the cavity affects microleakage at the margin restoration and increases the adaptation between cavity and restoration material. This research aims to determine microleakage in dental enamel using nanofiller composite resin restoration with fifth-generation total-etch adhesive and eight-generation self-etch adhesive. This research used 16 specimens premolars, which were prepared cavity Class I G.V. Black and divided into two groups (group A and B). Group A used nanofiller composite resin FiltekTM Z350 + fifth-generation total-etch Adper Single Bond 2 (n=8), group B used nanofiller composite resin Filtek TM Z350 + eight-generation self-etch Universal Single Bond Adper (n=8). The specimen isolated using nail polish except in the work area.,then immersed in methylene blue 1% at 25C (for 24 hours). After that, all specimens were washed and cut longitudinally. The results were observed using a Stereomicroscope and Scanning Electron Microscope (SEM). The observations results showed that the amount number of microleakage in group A (75%) less than in group B (100%), while the non-parametric statistic test using the Mann Whitney showed no significant differences (p0.143). Based on SEM images, the average distance between enamel and composite resin with total-etch adhesive was 1.40 0.007m, and 1.84 0.509 m for resin composite with self-etch adhesive. This research concluded that microleakage using nanofiller composite with the fifth-generation total-etch adhesive was smaller than nanofiller composite resin with the eighth -generation self-etch adhesive.KEYWORDS: Adhesive system, nanofillers composite resin, microleakage, enamel

Abstract

Nanofilled composite resin has a filler particles in the nanometer range, so that can improve physical properties and enhance esthetics. Surface roughness of nanofilled composite resin are measured fromthe condition of material that can absorp the solution. Water absorption is determined by solution ofimmersion. Gayo arabica coffee is one of immersion that can be absorbed by nanofilled composite resinand contain of acids. The aim of this study is to determine the surface roughness value of nanofilledcomposite resin after immersion in gayo arabica coffee. There were 10 specimens of nanofilledcomposite resin (merk Filtek Z350 XT) with cylinder size (d=10 mm; t=2 mm). Each specimen wasinitially immersed in distilled water at 37oC for 24 hours and its initial roughness was measured usingsurface roughness tester. Then, specimens were immersed in gayo arabica coffee at 55C for 4 days.After immersion, all specimens were measured using surface roughness tester to determine the finalroughness. The data was analyzed using paired t-test with significant value is p0.05. The resultshowed there was significant difference of surface roughness before and after immersion in gayoarabica coffee. The conclusion of this study there was increased in surface roughness nanofilledcomposite resin after immersion in gayo arabica coffee.Keywords : nanofilled composite resin, surface roughness, gayo arabica coffee.

Abstract

The home bleaching procedure is a tooth whitening process that can be done at home using a prostheticlikedevicecalledatrayornightguardwith16%carbamideperoxideconcentration.Chemicalssuchascarbamideperoxidecanhaveasensitiveeffectontheteeth.Greenpear(Pyruscommunis)isbelievedtohaveacontentthatcanremovestainsonthesurfaceoftheteethandwhitenteethsuchasmalicacid,citricacid, oksalat acid, sicamat acid, fumarate acid, tartaric acid and lactic acid. This study was alaboratory experimental study of the effectiveness of tooth discoloration applied with green pears(Pyrus communis) and then compared with the color of teeth applied to 16% carbamide peroxide. Toothcolor changes that occurs is measured using the shade guide. In the group of green pear juice (Pyruscommunis) it produces the final color A3.5 and A3, while in the carbamide peroxide group 16%produces the final color A1. The results of the study were analyzed using Wilcoxon and Mann Whitneyanalysis to see the comparison of the effectiveness of tooth color change in the teeth. Based on theresults of the study it can be concluded that the application of green pear (Pyrus communis) is lesseffective than the application of 16% carbamide peroxide.Keywords: Green Pear (Pyrus communis), Carbamide Peroxide, Home Bleaching
