<![CDATA[Introduction: Alginate impression material is widely used in dentistry. There are two types of alginate impression based on the setting time: fast setting (type I) and normal setting (type II). Setting time of alginate impression is affected by the ratio of powder and water, water temperature, also types of the alginate impression. In some dental treatments, dentists need to make modifications of alginate impression materials in the normal setting type to speed up the setting time and prevent maintenance delays. Objective: The objective of this study is to determine the effect of water temperature on the setting time of normal type alginate impression material. Methods: This laboratory experimental study were carried out on alginate impression materials of normal type which were tested in three temperature groups (±15°C, ±24°C, and ±40°C). The setting time is measured using a penetrometer in accordance with ANSI/ADA No. 18 equipped with a glass plate and a metal ring mold with a diameter of 30 mm and a height of 16 mm. Results: The results of statistical tests indicate the influence of water temperature on the setting time of the normal type of impression material carried out in all three temperature groups (p<0.05). Mann Whitney Test Results with p<0.05 showed a difference in the average setting time of each temperature group, in which the three groups are ±24°C to ±15°C, ±24°C to ±40°C, and ±15°C to ±40°C. The fastest setting time occurs in the test group with a temperature of ±40°C and the longest occurring in the testing group is ±15°C. Conclusion: There is an increase in the setting time of alginate impression materials in the normal setting type due to the influence of water temperature. Increased setting time by 23,2% faster at the temperature of ±40°C than the normal water temperature.]]>

<![CDATA[Background: The use of mouthwash has increased and become a habit since the Covid-19 pandemic. The use of mouthwash is recommended for prevention. The mouthwashes that American Dental Association (ADA) and Center for Disease Control and Prevention (CDC) recommended are chlorhexidine gluconate (CHX), hydrogen peroxide (H2O2), cetilpyridinium chloride (CPC), povidone iodine (PVP-I), dan chlorine dioxide (ClO₂). Universal composite resin is used for every tooth color requirement and has a chameleon effect that can disguise, eliminate, minimize, and neutralize mismatched colors. This study aims to determine various mouthwashes’ effects on the discoloration of universal composite resin. Method: This research is an experimental laboratory by comparing the color changes before and after treatment. Thirty samples of universal composite resin with a width of 10 mm and a height of 2 mm were divided into 5 mouthwash test groups and 1 control group. Color test using a Vita Easy Shade V spectrophotometer and the data were shown in DE assessment. Result: Data were analyzed with One Way ANOVA on DE assessment with the significance level p<0.05 on 5 test groups. Conclusion: The 5 groups of mouthwashes showed there was a color change in the DE assessment of universal composite resin]]>

<![CDATA[Essential oils are widely incorporated into dental materials to enhance their antibacterial properties, including patchouli essential oil (PEO) derived from Pogostemon cablin Benth. PEO contains bioactive compounds such as Patchouli Alcohol (PA), phenols, steroids, and terpenoids, which contribute to its antimicrobial activity. This study aimed to evaluate the effect of PEO addition on the setting time of glass ionomer cement (GIC). Twenty cylindrical GIC specimens (2 mm × 10 mm) were tested using Vicat’s needle and divided into four groups based on the powder:PEO:liquid ratios: Group A (control), Group B (2:1:1), Group C (3:1:2), and Group D (3:2:1). Data were analysed using One-Way ANOVA and Tukey’s test (p < 0.05). The addition of PEO to GIC’s liquid is significant (p < 0,05) decreased the setting time of group B, C, and D. Modifying GIC with PEO showed a significant decrease in setting time in group B with a comparison ratio (2 : 1 : 1). All results remained within ISO 9917-1:2007 limits. Further studies are needed to assess long-term stability and mechanical performance.]]>

<![CDATA[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.]]>

<![CDATA[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.]]>

<![CDATA[Introduction: Beta-tricalcium phosphate (βTCP) has higher solubility than hydroxyapatite (HA), allowing it to be more easily resorbed and replaced by newly formed bone. This higher solubility enables the release of calcium and phosphate ions that play important roles in bone remodeling and osteoblast activity; however, excessive ion release may lead to cytotoxic effects. Limestone, mainly composed of calcium carbonate (CaCO₃), can serve as a calcium source for the fabrication of βTCP. βTCP scaffolds can be combined with organic components such as chitosan and gelatin to form composite scaffolds for bone tissue engineering. Therefore, this study aimed to analyze the cytotoxicity of a β-tricalcium phosphate–chitosan–gelatin composite scaffold as a bone substitute. Methods: Type of research was experimental laboratory. Freeze-drying method was used to produce a composite scaffold which was divided into two groups: chitosan-gelatin scaffold as control group and βTCP-chitosan-gelatin scaffold (each group consisted of three samples) To evaluate cytotoxicity, composite scaffolds were tested on osteoblast cells and the MTT assay was measured and assessed based on time evaluation at 24 hours and 72 hours. Cytotoxicity was determined based on the percentage of viable cells obtained from the MTT assay. Results: Viable cells percentage on the chitosan-gelatin scaffold was 70.32% at 24 h and increased to 99.52% at 72 h. While on the chitosan-gelatin-βTCP scaffold there were 85.11% viable cells at 24 h and increased to 89.54% at 72 h. Statistical analysis using one-way ANOVA showed no significant difference among all groups (p>0.05). However, Fisher’s LSD test indicated a significant difference in cell viability between 24 hours and 72 hours within the chitosan gelatin group. Conclusion: The βTCP-chitosan-gelatin composite scaffold demonstrated no cytotoxic effect on osteoblast cells, indicating its biocompatibility and potential suitability as a bone substitute material.]]>
