Abstract

Wax is a soft and flexible material obtained from plants and insects or made synthetically and composed of high molecular weight organic molecules. One of the properties of dental wax or wax is the property of distortion, namely the return of the modified form of dental wax or wax to its original shape. Wax patterns or wax models are used as wax patterns in the manufacture of orthodontic appliances, complete dentures, and other prostheses that use plastic construction. Base plate wax is a dental wax for denture patterns based on acrylic resin. To evaluate wax distortion that occurs at room temperature for 24 hours. Testing of 141 wax samples placed at room temperature 25°C for 24 hours. One-way ANOVA test revealed a significant difference (p<0.05) in storage of wax at room temperature for 24 hours. There is an effect of temperature and storage time on the amount of wax distortion that occurs.

Abstract

Background: Nanofilled resin composites are popular for their aesthetics but are vulnerable to discoloration and surface degradation, particularly in acidic environments. Gochujang, a Korean chili paste, is increasingly consumed and may affect dental restorations. Objectives: To evaluate the effect of gochujang sauce immersion on the color stability and surface roughness of nanofilled resin composite. Methods: Thirty-three Filtek™ Z350 XT A3 samples were divided into three groups (n=11): immediate control, distilled water control, and gochujang treatment. The treatment group was immersed daily in a 1:1 gochujang-distilled water solution (16 h) and distilled water (8 h) for four days at 37°C. Color change (ΔE) was measured with a VITA Easyshade V spectrophotometer; surface roughness (Ra) with a Taylor Hobson Surtonic S-100. Results: Gochujang immersion significantly increased color change (ΔE, p<0.001) and surface roughness (Ra, p=0.009) compared to controls between groups (p<0.05). Conclusion: Gochujang immersion adversely affects both color stability and surface roughness of nanofilled resin composites.

Abstract

The lemongrass plant (Cymbopogon citratus) in Indonesia has great potential as a natural ingredient for medicines because it contains various compounds such as neral, citral, geranial acetate, flavonoids, and tannins. Previous research has demonstrated various pharmacological activities of kitchen lemongrass leaves, including antibacterial, antifungal, and anti-inflammatory properties. Encapsulation technology in the form of chitosan-NaTPP nanoparticles is used to maintain the activity of kitchen lemongrass leaf compounds. This research aims to determine the physical characteristics of the encapsulation of kitchen lemongrass leaf extract with several comparisons of chitosan and NaTPP by testing PSA (particle size analysis test), FTIR (functional group analysis test), viscosity, and stability, including pH and turbidity tests. Encapsulation with a 1:1 ratio of chitosan and NaTPP has a particle size of 524 nm and a PdI value of 0.481, classified as monodisperse (PdI <0.7). The pH value ranges from 6.46 to 7.30, and the viscosity value was 2.134–2.169 cP, which is still within mouthwash standards. The turbidity test showed stable encapsulation results. Therefore, encapsulation with a 1:1 ratio of chitosan and NaTPP is the most optimal choice and has potential for developing the therapeutic effect of mouthwash.

Abstract

The β-TCP material is a material of ceramic that often used in the medical and dental fields as a bone substitute material because it has biocompatible, bioresorbable and osteoconductive properties. Apart from that, this material is also biocompatible with tooth tissue, is non-inflammatory, and can regenerate dentin. Several studies have shown that the properties of β-TCP material can be a candidate for pulp capping material. These studies have also been carried out on experimental animals and showed good results. This article reviews the potential of β-TCP as a candidate pulp capping material in dentistry.

Abstract

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.
