Abstract

Background: Resin composite is one of many materials that are often used in daily dental practice because of its convenience and high aesthetic value. Resin composite consists of various materials, one of them is nanofil resin composite. Some research has shown that non-fiber resin composite has poor flexural strength. Therefore, fiber (FRC) can be added to the resin composite as a reinforcing material.Method: This study is based on a true-experimental, post-test only control group design with 16 specimen total of samples with 25x2x2 mm in the size. The samples were classified into two groups, the first group is the nanofil resin composite without the addition of non-dental glass fiber, and the second group is the nanofil resin composite with the addition of non-dental glass fiber. Data was tested using the parametric test, Independent T-test.Result: The average result of the flexural strength of the nanofil resin composite group without the addition of non-dental glass fiber was 102.7725 Mpa. As for the nanofil resin composite group with the addition of non-dental glass fiber is 166.1100 Mpa. The results of the independent T-test showed p-value = 0.000.Conclusion: It was found that nanofil resin composite with addition of non-dental glass fiber has a higher flexural strength than resin composite without addition of non-dental glass fiber so that it can be used as an alternative choice in applications in dentistry.

Abstract

Background: The type of fiber often used in dentistry is E-glass fiber, which has limited availability and relatively high prices. Non-dental glass fiber can be employed as an alternative in dentistry because its composition is nearly identical to E-glass fiber. Exposure of restorative materials to artificial saliva, designed to mimic the properties of normal human saliva, affects the mechanical properties of non dental glass fiber, including tensile strength. This research aims to determine the effect of immersion duration of non-dental glass fiber reinforced composite in artificial saliva on tensile strength.Method: The research method used is laboratory experimental analytic with a post-test only control group design. Samples are divided into three treatment groups with immersion in artificial saliva for three times (2, 7, and 14 days). Tensile strength is conducted using a Universal Testing Machine (UTM).Conclusion: The conclusion drawn from this research is that immersion duration in artificial saliva has a significant effect on tensile strength of non-dental glass fiber reinforced composite. The tensile strength of non-dental glass fiber reinforced composite after immersion for 14 days shows higher results compared to immersion for 7 and 2 days.

Abstract

Background: The success of bonding quartz fiber posts to root dentin hinges on various factors, including the bonding system. This experimental study aimed to investigate pull-out bond strength (PBS) of quartz fiber post toward root denting using different adhesive systems.Method: Thirty six human teeth (n=12) were embedded in acrylic resin blocks. Crowns were sectioned, leaving the root portion 20mm in length. Root canals were treated with standard endodontic protocols using the rotary instrument, obturated with gutta percha, and prepared for post cementation, leaving a 4mm apical seal. Root canals were prepared uniformly. After simple randomization, samples were divided into three groups according to the adhesive systems (Allcem core dual resin, NOVA resin self-adhesive, and GC FUJI Luting & Lining). Cementation procedures followed to manufacturer instructions. Post cementation was tested for PBS using a Universal Testing Machine (TN20 MD) until the posts were detached. Data were analyzed using the Kruskal-Wallis and Mann-Whitney U post hoc test (α=0.05)Result: The Kruskal-Wallis test indicated significant differences among the groups (P < 0.001), with GC FUJI Luting & Lining showing the significantly lowest PBS.Conclusion: Different cementation materials exhibit varying bond strengths. GC FUJI Luting & Lining provided inferior bond strength, making it the least recommended choice for bonding quartz fiber posts to root dentin.

Abstract

ABSTRACTBackground: Periodontitis is a multifactorial inflammatory condition that progressively damages the tooth-supporting structures, including the alveolar bone and periodontal ligament. This process involves a rise in pro-inflammatory cytokines, such as IL-6, which are essential agents in the inflammation and tissue destruction. Aloe vera (Aloe vera) and manuka honey are recognized for their ability to reduce inflammation and suppress the release of pro-inflammatory signaling molecules, such as IL-6. This study aims to evaluate the effectiveness of the combination of Aloe vera and Manuka honey in reducing IL-6 level in periodontitis rats.Method: Thirty rats were randomly assigned to four experimental groups: a control group, Aloe vera group, Manuka Honey group, and a group receiving a combination of Aloe vera and Manuka Honey. The Aloe vera and Manuka Honey treatments were administered via a gingival injection at a dose of 150 uL. After five days treatment, the rats were euthanized. An ELISA (Enzyme-Linked Immunosorbent Assay) was  conducted on the gingival tissue to measure the concentration of Interleukin-6 (IL-6).Result: The combination of Manuka honey and Aloe Vera significantly reduced IL-6 levels compared to the control group (p=0.000).Conclusion: The combination of Aloe Vera and manuka honey are effectively and  significantly reduced on IL-6 level.
