“…Hal tersebut mempengaruhi keausan dari resin komposit, sehingga akan mengakibatkan penurunan kekerasan permukaan resin komposit. 4 Lemon (Citrus lemon) sejenis jeruk yang dikenal juga dengan sebutan sitrun, jeruk sitrun (dari bahasa Belanda, citroen), buahnya berbentuk bulat lonjong, ada tonjolan pada ujungnya, warna kulit buah matang kuning cerah, rasanya asam, sepet, sedikit manis 5 . Buah lemon (citrus lemon) merupakan tanaman yang memiliki manfaat sebagai antioksidan alami karena memiliki kandungan vitamin C, asam sitrat, minyak atsiri, bioflavonoid, polifenol, kumarin, flavonoid, dan minyakminyak volitalil pada kulitnya.…”

Composite resin is a restoration material that is often used because the composite resin has good aesthetic value like mimetic the teeth color. Composite resins have a physical and mechanical condition. One of the mechanical condition is hardness. The surface hardness of composite resins is the surface resistance of the composite resin material to the applied pressure. One of the factors influencing composite hardness is the food and beverages consumed. Consuming acidic drinks continuously for a long time period can erode composite resin filling. The purpose of this study was to determine the effect of soaking into a citrus lemon on the hardness of nanohybrid composite resin. This type of research was true experimental with pre-test post-test with control group design using 24 composite resin samples which are divided into 4 groups with 6 samples each. The groups in this study were nanohybrid composite resins soaked with citrus lemon and aqua dest for 60 minutes and 120 minutes. The hardness tested using a Vicker hardness tester. The results of the study using the LSD (Least Significant Difference) test showed that the significance value of p= 0.014 (p<0.05), which means that the use of citrus lemon for 120 minutes affected the hardness of nanohybrid composite resin. In conclusion, soaking with citrus lemon for 120 minutes reduces more the hardness of nanohybrid composite resin compared with soaking for 60 minutes.

“…15 Other factors affecting polymerization of composites include: exposure time, exposure distance and composite resin thickness. 8 All groups were irradiated for 20 seconds as recommended with a irradiation distance of 0 mm in the perpendicular position and with the same thickness of 2 mm. These factors were used as dependent variables applied to all samples in order that they did not affect the hardness of the composite resin.…”

“…The hardness of nanofilled composite resins is also influenced by water absorption. 8 The specific resin used in this research was Filtex TM Z350 XT transluscent shade which contains bis-GMA, UDMA, TEGDMA and bis-EMA resin. TEGDMA constitutes one of the comonomers possessing the largest hydrophilic properties at 69.51 µg/mm 3 .…”

“…6 One such vatable property is hardness 7 which can, consequently, be considered a measure of the resistance to wear of restoration materials since it can influence mechanical friction during mastication and tooth brushing. 8 The properties of composite resin potentially affecting its hardness include: water absorption, composite resin hardness, irradiation distance and material polymerization. 8 The polymerization of composite resin materials can be disrupted when their surfaces are exposed to air.…”

“…8 The properties of composite resin potentially affecting its hardness include: water absorption, composite resin hardness, irradiation distance and material polymerization. 8 The polymerization of composite resin materials can be disrupted when their surfaces are exposed to air. The disturbance causes obstruction of the polymerization process, producing an oxygen inhibition layer (OIL) which can then affect the prognosis of composite restorations because it reduces surface hardness, durability and marginal adaptation.…”

Background: Loss of tooth structure is a consideration in the performance of restorative treatment involving nanofilled composite resins. Material polymerization factors and water absorption can affect the hardness of composite resins. Imperfect polymerization producing an oxygen inhibited layer (OIL) and causing water absorption can even compromise the hardness of nanofilled composite resins. Tamarind soft drink, on the other hand, has an acidic pH that compromises the hardness of nanofilled composite resins. Purpose: This study aimed to reveal the effects of glycerin application on the hardness of nanofilled composite resins immersed in tamarind soft drinks. Methods: The research constituted a laboratory experiment using 24 nanofilled composite resin samples with diameters of 5mm or 2mm, divided into six groups, namely: Group G, Group G AS 60, Group G AS 120, Group TG, Group TG AS 60, and Group TG AS 120. Glycerin was applied to the surfaces of three groups before curing, while the other three groups were not treated with glycerin. Finishing was subsequently conducted on all samples using a highspeed handpiece and superfine finishing bur, before they were polished with a low speed handpiece. The samples were then divided into specific groups, namely: a group with a 120-minute immersion time, a group with a 60-minute immersion time, and a group which was not immersed and maintained at a temperature of 37 o C. Each sample was tested at three points using a Vickers hardness tester (VHT). Results: The results showed that the groups with glycerin had a higher hardness level than those groups. In addition, the non-immersed groups had a higher hardness level than those groups which were immersed. The one-way ANOVA test results confirmed that there was a statistically significant difference (p<0.05) between all groups. Conclusion: The application of glycerin to nanofilled composite resins immersed in tamarind soft drinks can increase their hardness levels.

Background: Composite resin often used as a restoration material due to its advantages in the aesthetic field. The bulk-fill type is one of the composite resin that can be applied directly into cavities as deep as 4 mm, so that restoration procedure becomes easy and effective. Hence, exposure to various acidic drinks can reduce the hardness of composite resins and eventually lead to failure of the tooth restoration process.Objective: This research aimed to evaluate the effects of several commercial acidic drinks, (carbonated, isotonic, and yogurt) on the hardness of bulk-fill composite resins.Method: This research was an experimental study with a post-test control group design. Twenty-four specimens were made with the size 10 x 4 mm using the metal mold rings. Specimens were divided into 4 groups for artificial saliva (served as a control), carbonated, isotonic, and yogurt. Specimens were immersed in storage agents for 5 seconds followed by artificial saliva for 5 seconds. This cycle was repeated 20 times for 14 days. The bulk-fill composite resin hardness was measured using a Micro Vickers Hardness Tester with a load of 100 grams for 10 seconds. Statistical analysis was performed using One Way ANOVA and Post Hoc LSDResults: Data were normally distributed and homogeneous with p > 0.05. The One Way ANOVA test showed the biggest difference in bulk fill composite resin between 4 groups (p < 0.001). The Post Hoc LSD test showed significant differences between all groups (p < 0.001)Conclusion: Carbonated, isotonic, and yogurt drink significantly decreased surface microhardness of bulk-fill composites resin but the carbonated drinks greatly reduce the hardness value since it has the lowest pH of 2.3.
