One of the most important procedures in denture fabrication and orthodontic treatment is molding the patient’s detail oral cavity to determine the treatment planning. This procedure was done by using alginate impression material or irreversible hydrocolloid in which the basic material is sodium alginate imported from abroad because it is extracted from brown algae which its habitat is not in Indonesia so that it is causes the impression material is relatively expensive roomates is impact to high cost of dental treatment. Indonesia as the archipelago country has availability of abundant brown algae Padina sp. Especially in Puntondo-Punaga seashore, South Sulawesi, but it has not Cultivate yet by the local society because it is never discovered by alginate industry so it is just grow wild and its potency is useless. This experiment identified the purposes of how much sodium alginate is produced from Padina Sp. Extraction as the basic matter of irreversible hydrocolloid. The design of this study is experimental design with one shot case study method. In early stage research, extraction of alginate in the form of sodium alginate. After that, they are weighted by using analytical weight in milligrams (mg) unit. Then, it is compare with the standard sodium alginate to observe the similarity of molecules by using FTIR (Fourier Transform Infra Red) device. Data were Analyzed using mean differences. Based on Padina extracted, produced 12.86 g of sodium alginate content or 28.4% from the cleaning algae was used roomates total weight is 45 g. Based on FTIR test, showed that sodium alginate is extracted similar to the standard sodium alginate with the found of hydroxyl, carboxylic acid, ether group and the which is the composer of sodium alginate. In conclusion, from both of infra red spectrum pattern, it was observed unsignificant difference. Extracted sodium alginate Padina is same with the standard sodium alginate and it has 12.86 g content.

This study aimed to investigate the potential use of brown algae Sargassum polycystum as irreversible hydrocolloid (alginate) impression material. Potassium alginate extracted from Sargassum polycystum was prepared in three different compositions (14%, 15%, and 16%) and mixed with other standard components to form an alginate impression material. Prior to that, the purity of potassium alginate was quantified with Fourier Transform Infrared Spectroscopy (FTIR) analysis. As a control material, the alginate impression material from a commercially available product was used. All alginate impression materials were then applied to a die stone model. Dimensional accuracy was measured by calculating the mesiodistal width of incisors in the generated dental cast using a digital caliper 0.01 accuracy (five replications). In addition, to evaluate the dimensional stability, the impression results were poured at four different periods (immediately, 5 min, 10 min, and 15 min). An independent t-test was performed to compare the measurement results with p < 0.05 considered significant. Analytical results confirm that the impression material containing 15% potassium alginate gives the best dimensional accuracy similar to control (p > 0.05). Meanwhile, the optimal dimensional stability was produced in the impression material containing 16% potassium alginate. Our study suggested that brown algae Sargassum polycystum has a promising potential to be used as an alginate impression material in clinical application.

Dental Impression

Dental impression is a source of cross infection and transmission of diseases. Conventional disinfection may lead to a change in physical properties. Self-disinfectant irreversible hydrocolloid is an alternative to the disinfection and can prevent microbial cross contamination. The present study evaluates the physical properties of irreversible hydrocolloid impression material incorporated with 0.5%, 1.0% and 1.5% w/w silver nanoparticles (AgZrPO4, Sunshine Factory Co.,Ltd, China). The working time and detail reproduction were tested according to ISO 21563:2013 with some modification. The result showed that AgZrPO4 did not significantly affect the physical properties of the impression material. Based on this in vitro study, AgZrPO4 can be added to the impression material for its antimicrobial benefit without significant changes in the physical properties of the material.

Quick setting dental impression materials are nothing new in the paleontology laboratory. In a paleontological note published in the Journal of Paleontology on “The Use of Dental Impression Material For Molding Macrofossils” (Quilty & Williams, 1975), the products Xantopren and Optosil were introduced as a simple and fast method of obtaining precision molds in 1-3 minutes. Since the mid-1970's these products have been replaced by vinyl polysiloxanes.
