Background: Ironwood bark extract contains antioxidant properties such as flavonoids, phenolics, and proanthocyanidins, which can stabilize ROS in the body and help accelerate wound healing. The liver plays a role in nutrient metabolism, detoxification, and ROS production. The lack of antioxidants to neutralize excess ROS makes the liver vulnerable to damage. Purpose: This study aimed to determine that there was no toxic effect of giving ironwood bark extract (Eusideroxylon zwageri) doses of 1.250 mg/kg, 2.750 mg/kg, and 4.750 mg/kg on the liver of Wistar rats based on histopathological features of hydropic degeneration and necrosis. Methods: Pure laboratory experimental quantitative (true experimental) with a post-test-only research design with control group design and One Way Anova statistical test. Treatment was given to 4 groups, namely group (K) was given aquadest control, group (T1) was given ironwood bark extract at a dose of 1.250 mg/kgBW, group (T2) was given ironwood bark extract at a dose of 2.750 mg/kgBW, and group (T3) given ironwood bark extract at a dose of 4.750 mg/kgBW. Results: The results showed no significant difference between the four treatment groups based on the average percentage of hydropic degeneration and necrosis. Conclusion: There was no toxic effect of giving ironwood bark extract doses of 1.250 mg/kgBW, 2.750 mg/kgBW, and 4.750 mg/kgBW on the liver of Wistar rats based on histopathological appearance of hydropic degeneration and necrosis for 14 days.

Background: Ironwood bark extract (Eusideroxylon zwageri) has antioxidant properties such as tannins, phenolics, flavonoids, saponins and alkonoids. Most compounds in the ironwood bark extract were phenolics (31.28 mg GAE/g), flavonoids (30.48 mg CE/g), and proanthocyanidins (183.30 mg PE/g). These can be used as alternative herbal medicines, but also has toxic effects, so a toxicity test is necessary. Toxicity tests can be seen through histopathological parameters based on glomerular hypertrophy and hydropic degeneration. Purpose: To determine the toxic effect of ironwood bark extract administration at doses of 1,250 mg/kg, 2,750 mg/kg, and 4,750 mg/kg orally on the kidneys of Wistar rats based on histopathological appearance of glomerular hypertrophy and hydropic degeneration. Methods: Pure experimental study with a posttest-only with control design, consisting of 4 groups with 3 treatment groups given ironwood bark extract at doses of 1,250 mg/kg, 2,750 mg/kg, and 4,750 mg/kg, and 1 control group was given distilled water 2x1 ml every 24 hours orally for 14 days. Results: In administration of ironwood bark extract at doses of 2,750 mg/kgBW and 4,750 mg/kgBW, glomerular diameter was found increased. The histopathological hydropic degeneration showed a score of 1 in all dose groups. The research data were analyzed using the One Way Anova and Kruskal Wallis tests. Both tests showed no significant differences between groups. Conclusion: There was no toxic effect of ironwood bark extract at doses of 1,250 mg/kg, 2,750 mg/kg, and 4,750 mg/kg on the kidneys of Wistar rats based on histopathological appearance of glomerular hypertrophy and hydropic degeneration.

Background: The face's vertical dimension or vertical height is the distance between two anatomical points, namely the points on the maxilla and mandible. In measuring the vertical dimension, vertical dimensions of rest (DVR) and vertical dimensions of occlusion (DVO) must be measured. The difference between the vertical dimension of rest (DVR) and the vertical dimension of occlusion (DVO) is called the freeway space (FWS) or interocclusal distance. Freeway space is a key requirement for optimal comfort and function of a partial or complete denture. Each individual's freeway space distance is the movement of muscle function, which can be measured by direct methods such as the Willis method using calipers and the digital photo analysis method using computer software. Two measurement methods can be used to measure freeway space distance direct and indirect. Purpose: To analyze the difference between freeway space distance measured by the Willis method and by digital photo analysis of Adobe Photoshop and Corel Draw graphic design software in the Banjar tribe (a review of students at the Faculty of Dentistry, Universitas Lambung Mangkurat Banjarmasin). Methods: This study is a quantitative study with an analytic observational method and a cross-sectional approach. This study was conducted by collecting data simultaneously at one time by comparing three different methods on the same sample without being given any treatment. Results: One Way ANOVA test is 0.296 (P>0.05) which means there is no significant difference. Conclusion: There is no significant difference between the results of measuring freeway space distance using the Willis method with a digital caliper and digital photo analysis with Adobe Photoshop and Corel Draw software.

Background: Root canal treatment is a stage of treating pulp infection by removing the necrotic tissue and eliminating microorganisms. Inadequate sterilization cause persistent root canal bacteria, including Enterococcus faecalis. The irrigation solution that has become the gold standard in root canal treatment is Sodium hypochlorite but it has some weaknesses. Kelakai leaf extract can be an alternative root canal irrigation because it has minimal side effects and antibacterial compounds such as flavonoid, saponin, alkaloid, and tannin.Methods: This research was a true experimental laboratory with posttest only and control group design. The research using 5 treatment groups with 3 replications, so that total sample was 15 samples. Group 1-4 were kelakai leaf extract concentrations of 25%, 50%, 75%, 100% and group 5 was Sodium hypochlorite 2,5%. The parameter measured was the diameter of the inhibition zone (mm) formed on MHA.Results: One Way Anova and Post Hoc LSD test results showed a significant difference between each treatment group of kelakai leaf extract compared with Sodium hypochlorite 2,5%. Kelakai leaf extract 25%, 50%, 75%, 100% concentrations, and Sodium hypochlorite 2,5% had an average inhibition zone diameter which were 9.47 mm, 14.64 mm, 17.91 mm, 21.24 mm, and 23.27 mm.Conclusion: Kelakai leaf extract concentrations of 25%, 50%, 75%, and 100% had inhibitory activity against Enterococcus faecalis but had not been equivalent to Sodium hypochlorite 2,5%.
