Abstract

Background: Xylotrupes gideon is a harmful insect because it damages the shoots of coconut trees. Xylotrupes gideon has begun to be used in the form of nanochitosan as an alternative in dentistry. The addition of nanochitosan to Glass Ionomer Cement (GIC) material is a modification to improve the properties of GIC, such as surface roughness caused by acidic conditions (critical saliva pH). Nano-sized chitosan is able to increase stability and better absorption, thus inhibit demineralization and increase tooth hardness. This research aimed to investigate the effect of nanochitosan from Xylotrupes gideon on the surface roughness of GIC at critical saliva pH.Method: This research type conducted is an experimental laboratory. Samples of 10 mm (height) x 2 mm (diameter) divided into 2 groups, (A) Unmodified GIC (control group), (B) GIC modified with 10% nanochitosan solution. Samples of the treatment and control group are stored in the incubator at 370C for 1 hour before early surface roughness testing and continued in critical saliva pH (5,5) for 7 days in the incubator before the final test. The surface roughness tester using sutrotonic s-100 series.Result: There was an increase in the surface roughness of conventional GIC by 0.133 µm and GIC nanochitosan by 0.122 µm. The results of the paired t-test before and after immersion in the two groups showed that there was a significant difference (p <0.05) between conventional GIC and nanochitosan GIC. The independent t-test results showed that there was no significant difference (p> 0.05) between the nanochitosan GIC and conventional GIC.Conclusion: Nanochitosan can reduce the surface roughness value of GIC at critical saliva pH, although there is no significant difference to conventional GIC.

Abstract

Background: Composite resin is a filling material that is similar in color to tooth enamel and can be used widely for various cases, especially for the restoration of anterior teeth. Composite resins have been modified and improved to obtain maximum restoration results, one of which is nanofiller. Nanofiller composite is known to have a high level of smoothness, but polishing remains the key to success in the final filling process. There are many types of polishing on the market, this indicates that not all dentists use the same type of tools. This study aimed to determine the effect of various types of polishing bur on the surface roughness of nanofiller.Method: The type of research conducted was an experimental laboratory. Cylindrical samples with a total of 40 samples measuring 10 mm x 2 mm were divided into 4 groups. Samples were soaked in distilled water and stored in an incubator for 24 hours at 37oC. The samples were polished using different types of bur except for the control group. Samples were tested for surface roughness using a surface roughness tester and scanning electron microscopy (SEM). Result: This study shows differences in the surface roughness of the nanofiller composite after being polished using different types of polishing burs. The results of the one-way ANOVA test indicated that there was a significant difference from the average of the four sample groups.Conclusion: Polishing burs can produce different surface roughness of nanofiller composite.

Abstract

Background: Patients with xerostomia generally have an acidic salivary pH. Low oral pH increases the occurrence of tooth caries and development of oral lesions such as recurrent aphthous stomatitis (RAS) which are prone to occur in patients with xerostomia. Trigona spp. propolis extract with antimicrobial compounds was used as an additional natural ingredient in saliva substitute to inhibit the growth of Streptococcus mutans and prevent the decrease of salivary pH in patients with xerostomia. This study aimed to determine the effect of Trigona spp. propolis extract to saliva substitute pH as therapy for xerostomia with antimicrobial activity. Method: This study was experimental laboratory, namely Post-test only Control Group Design. The propolis Trigona spp. extract used in this study was extracted using maceration method with 70% ethanol as solvent which was then diluted into 5 concentrations 1,25%, 2,5%, 5%, 10%, 20%. This study used Streptococcus mutans (ATCC 25175) and saliva substitute with pH of 6.8. The research includes phytochemical test, absorbance measurement and pH test. Result: There is a significant difference in the pH value between saliva substitute induced with Streptococcus mutans with Trigona spp. propolis extract and the control group. Data analysis using One-way ANOVA test showed a significant value of

Abstract

ABSTRACT Background: Tooth loss can be caused by periodontal disease, caries, and other factors. Dental implants made of titanium are a common solution to replace tooth loss. Titanium grade 5 (Ti-6Al-4V) is often chosen for an implant. Modern commercial implant surface roughness (Ra) ranges from 1 to 2 μm. Surface roughness has an important role in osseointegration. The acid etching method can be used to improve surface roughness. This study evaluates titanium alloy surface roughness after etching with varying concentrations of H3PO4 acid.Method: A laboratory experiment with a pre-test and post-test group design. 25 titanium alloy samples were divided into 5 groups (n=5) and treated with saline, HCl 37%, and H3PO4 acid 38%, 48%, and 58%. Surface roughness was measured using a surface roughness tester, while EDS and SEM tests analyzed titanium composition and surface characteristics.Result: The titanium used in this study is a titanium alloy. Surface roughness modification using acid had a higher roughness compare to saline with significant different (p<0.05). Surface roughness in the group H3PO4 48% and 58% had a lower roughness compared to HCl 37% but no significant different (p>0.05). Referring to the SEM results, each acid showed morphological changes on the surface and for saline there were no morphological changes.Conclusion: Varying concentrations of H3PO4 acid can effectively improve the surface roughness of titanium alloys, with solutions at 48% and 58% demonstrating similar effectiveness to 37% HCl acid.
