Abstract

Background: Oxidative stress is an imbalance between free radicals and antioxidants, characterized by increase in malodialdehyde (MDA) levels. Stress oxidative caused by paracetamol overdose consumption and can be a serious problem for the structure and liver cell function. Oxidative stress prevented and controlled by antioxidant. Longan peel has phenolic and flavonoid which can potentially be sources of natural antioxidants. This study aimed to prove the longan peel extract had an antioxidant effect that could affect the oxidative stress in rats induced by toxic doses of paracetamol. Method: : Experimental research with control group design. Group P1, P2, and P3 were treatment group induced by paracetamol with a toxic dose of 2000 mg/kgBW and given extracts of longan peel (Dimocarpus longan L.) with multilevel doses, that were 25 mg/kgBW, 50 mg/kgBW, and 75 mg/kgBW wistar rat. Then, blood samples from each group were collected and measured plasma MDA levels and the animals were terminated, then their livers were taken for measurement of liver SOD enzyme activity. Result: One Way ANNOVA test showed a significant difference in plasma MDA (p=0,000) in the whole group of wistar rats. Significant differences were also shown on the examination of plasma MDA levels in the K1-K2, K2-P1, K2-P2, and K2-P3 groups (p<0,05). Conclusion: Longan peel extract had the effect of reducing plasma MDA levels of wistar rats induced by toxic doses of paracetamol compared to the control group.Keywords: Paracetamol, longan peel extract, MDA.

Abstract

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.

Abstract

Background: Osteoporosis is one of chronic degenerative diseases especially in postmenopausal women, characterized by a decreased bone mass due to imbalance activity between osteoblasts and osteoclasts. Recently, oxidative stress is believed to play an important role in osteoporosis pathogenesis. Oxidative stress is commonly considered as the consequence of an imbalance between pro and antioxidants species, which results in damage in the affected tissue. Malondialdehyde (MDA) is frequently used as a biomarker of oxidative stress in many health problems since MDA is produced at high levels during lipid peroxidation. Meanwhile, glutathione is well known as one of antioxidant which against oxidative stress by preserving its homeostasis in the reduced form of glutathione sulfhydryl (GSH) and the oxidized form of glutathione disulphide (GSSG). This study was aimed to determine the association between MDA, GSH/GSSG ratio and bone mineral density (BMD) in postmenopausal women.Materials and method: We conducted a cross-sectional study in 40 postmenopausal women. MDA and GSH/GSSG ratio were assessed by enzyme-linked immunosorbent assay (ELISA). Bone mineral density (BMD) was obtained from secondary data. The statistical analysis was conducted using Spearman rho’s correlation test.Results: Based on the test, we didn’t found significant correlation between MDA and BMD (r=-0.054, p=0.741), but we found significant moderate correlation between GSH/GSSG ratio (r=0.436, p=0.005) and BMD in postmenopausal women. Conclusion: There was no correlation between MDA and BMD in postmenopausal women. However, there was significant moderate correlation between GSH/GSSG ratio and BMD in postmenopausal women.Keywords: MDA, GSH/GSSG ratio, BMD, osteoporosis

Abstract

Background: The most restoration material used currently in dentistry was composite resin. The newest generation of composite resin was bulk-fill composite resin. The bulk-fill composite resin had advantages of lower polymerization contraction and a more straightforward and faster restoration technique. One of the factors which could affect the hardness of composite resin was the consumption of acidic drinks. The acidic beverage that people often consumed is coffee. A few coffee brewing methods were espresso and drip brewing.Objective: This research aimed to identify the effects of coffee soaking through espresso and drip brewing methods on bulk-fill composite resin's hardness.Methods: his research was experimental research, with a post-test control group design and a total sample of 27 samples. The soaking process was taken for seven days at a temperature of 37˚C on artificial saliva, espresso, and drip brewing coffee methods. The hardness of bulk-fill composite resin was measured after seven days by using Vickers hardness. The statistic test exerted One-Way ANOVA.Results: This research found a significant difference in bulk-fill composite resin's hardness among all groups, p-value = 0.00 (p<0.05). The result of the post-hoc LSD test showed a significant difference in the change of bulk-fill composite resin hardness between the artificial saliva group and espresso group (p=0,00) and no significant difference found between the artificial saliva group and drip brewing group (p=0.85).Conclusion: Soaking with espresso coffee has the smallest hardness value compared to soaking with drip brewing coffee and artificial saliva, so soaking with espresso coffee is the most influential on the hardness of the bulk fill composite resin.

Abstract

Background: Composite resins are dental restorative materials that are widely used and have high aesthetic value compared to other materials. However, acidic environmental conditions can degrade the composite resins, resulting in increased surface roughness of the resin, and consequently lead to an increased risk of caries.Objective: the purpose of this study was to evaluate the effect of immersion in acidic drinks on the surface roughness of composite resins,Method: In this study 24 samples of bulk fillTM  composite resins were used. Samples were divided into four groups. Each sample was immersed for 5 seconds in either artificial saliva (control), carbonated beverage, isotonic, or yogurt, and followed by 5 seconds immersion in saliva. This cycle was repeated for 20 times for 14 consecutive days. The roughness of composite resin before and after 14 days immersion was measured by using a profilometer. Microscopic structures were analyzed by Scanning electron Microscope (SEM). Statistical analysis was used paired t-test, Anova and Post Hoc LSD.Results: Data from each sample group was normally distributed- with p > 0.05. The paired t-test for each group showed a p-value < 0.05, which indicates there was a significant difference between surface roughness before and after immersion. ANOVA analysis revealed that there was a difference in the surface roughness between groups LSD test, showed that there was difference in the surface roughness between artificial saliva with carbonated drink, isotonic drink with carbonated drink, yoghurt drink with carbonated drink (p<0.0001), between artificial saliva group with yoghurt drink, yoghurt drink with carbonated drink, yoghurt drink with isotonic drink (p <0.05) which means there was a significant difference between group. Meanwhile, the isotonic drinks with artificial saliva obtained results (p>0.05), which means there is no significant difference.Conclusion: Exposure of carbonated drinks, yoghurt drinks, and isotonic drinks can significantly increase the roughness of the surface Bulk Fill resin composite compared to exposure of artificial saliva.Keywords: Composite resin, Bulk Fill, Surface Roughness, Acid

Abstract

Vitamin D and calcium deficiencies are often associated with increased oxidative stress. Oxidative stress conditions can cause cell damage and metabolic stress and induce degenerative diseases. Several parameters that are often used to measure oxidative stress are MDA (malondialdehyde) and SOD (superoxide dismutase) which can be found in blood or body tissue. This study aims to determine MDA levels and SOD activity in the livers of mice with vitamin D and calcium deficiency. This research used a pre-experimental design with a static group comparison design. A total of 12 male Wistar white rats (Rattus novergicus) were divided into two groups. The first group (K+) is a healthy control group without any treatment and the second group (K-) is a deficiency group given feed without vitamin D and calcium content (Modified AIN-93M (vitamin D and calcium depleted)). After 14 days of treatment, the MDA levels and SOD activity in the liver tissue were seen. MDA levels were measured using TBARS (Thiobarbituric Acid Reactive Substances) and SOD activity was measured using the Superoxide Dismutase (SOD) Activity Assay Kit. The results showed that MDA levels in the deficiency group (K-) were higher than in the control group (p<0.001) and SOD activity was lower than in the control group (p<0.001). MDA levels were higher and SOD activity was lower in the group of deficient mice (K-) compared to the group of healthy control mice (K+). Vitamin D and calcium deficiency conditions increase oxidative stress conditions in the liver of rat.   ABSTRAK Defisiensi vitamin D dan kalsium sering dihubungkan dengan peningkatan stress oksidatif. Kondisi stres oksidatif dapat menyebabkan kerusakan sel dan stress metabolik dapat menginduksi penyakit degenerative. Beberapa parameter yang sering digunakan untuk mengukur stres oksidatif yaitu MDA (malondialdehyde) dan SOD (superoxide dismutase) yang bisa ditemukan di darah atau jaringan tubuh. Penelitian ini bertujuan untuk mengetahui kadar MDA dan aktivitas SOD pada organ hati tikus dengan defisiensi vitamin D dan kalsium. Penelitian ini menggunakan rancangan pra-eksperimental (pre-experimental) dengan design static group comparison. Sebanyak 12 ekor tikus putih (Rattus novergicus) jantan galur Wistar dibagi menjadi dua kelompok. Kelompok pertama (K+) yaitu kelompok kontrol sehat tanpa diberikan perlakuan apapun dan kelompok kedua (K-) yaitu kelompok defisiensi dengan diberikan pakan tanpa kandungan vitamin D dan kalsium (AIN-93M Termodifikasi (vitamin D and calcium depleted)). Setelah 14 hari perlakuan, dilihat kadar MDA dan aktivitas SOD di jaringan organ hati. Pengukuran kadar MDA menggunakan TBARS (Thiobarbituric acid reactive substances) dan pengukuran aktivitas SOD dengan menggunakan Superoxide Dismutase (SOD) Activity Assay Kit. Hasil penelitian menunjukkan kadar MDA pada kelompok defisiensi (K-) lebih tinggi dibandingkan kelompok kontrol (p< 0.001) dan aktivitas SOD lebih rendah dibandingkan kelompok kontrol (p<0.001). Kadar MDA lebih tinggi dan aktivitas SOD lebih rendah pada kelompok tikus defisieni (K-) dibandingkan kelompok tikus kontrol sehat (K+). Kondisi defisiensi vitamin D dan kalsium meningkatkan kondisi stres oksidatif pada organ hati tikus.

Abstract

Background: Disinfection of alginate impressions is performed to prevent cross-infection. Alginate possesses properties of imbibition and syneresis which affect the dimensional stability of the impression. The disinfectant solution, hypochlorous acid (HOCl), is non-toxic, non-irritating, and non-corrosive at the appropriate concentrations. Hypochlorous acid has higher antimicrobial activity than sodium hypochlorite (NaOCl). Objective: This study aimed to determine the effect of spraying 0.01% and 0.02% HOCl with contact durations of 1 and 5 minutes on the dimensional stability of alginate impressions. Methods: This was a laboratory experimental study with a Post-Test Only Control Group Design. A total of 24 samples were divided into 4 treatment groups and 2 control groups. The dimensional stability of the alginate impressions was assessed by the difference in anteroposterior and mediolateral dimension measurements between the master model and the resulting gypsum casts, using a digital caliper. Measurements were taken 3 times by 3 different observers, followed by a two-way ANOVA statistical test. Results: The results of the two-way ANOVA test showed no significant difference between the groups with variations in concentration or contact duration. The largest dimensional difference was found in the control group sprayed with 5.25% NaOCl. Conclusion: Spraying alginate impressions with 0.01% and 0.02% HOCl with contact durations of 1 and 5 minutes does not affect the dimensional stability of the alginate impressions.
