Abstract

Background: Calcium hydroxide is a material that is widely used in pulp capping treatment. However, the use of this material causes tunnel defects due to the large absorption of calcium. This can be manipulated by creating an encapsulation formula. Stichopus hermanii is a marine biota that contains lots of hyaluronic acid and can be used as an encapsulation material which also plays a role in cell regeneration. The characteristics of the microencapsulated calcium hydroxide preparation with Stichopus hermanii as pulp capping material through an in vitro study.Method: Stichopus hermanii was made freeze dry and dissolved with 1% acetic acid to obtain a gel concentration of 0.2%, 0.4%, and 0.8%. Next, calcium hydroxide powder is added with a ratio of 1: 6 and tripolyphospate (TPP) is added as a cross-linker agent and the mixture is stirred until homogeneous. The test material formed was subjected to SEM, PSA and cytotoxicity tests.Result: The cytotoxicity test showed that all of the test materials (0.2%; 0.4%; 0.8%) were not toxic, especially at a concentration of 0.2%. The PSA test results indicate that this encapsulation shows the micro particle size formed. The SEM test shows a rough and stringy surface shape, where at a concentration of 0.2%, a smoother morphological formation is found.Conclusion: The in vitro study showed that the microencapsulation of calcium hydroxide with Stichopus hermanii as a pulp capping material showed the characteristics of the non-toxic material, the micro size and the rough and fibrous surface shape.

Abstract

Cross infection is the transfer of microorganisms that can occur from individual to individual or an object. COVID 19 is an infectious disease that can cause cross-infection in dentistry. One example is making a working model of gypsum material which can cause cross-infection from patients to dentists or technicians, so it is necessary to control infection by mixing sodium hypochlorite disinfectant solution into type III gypsum material (dental stone). This study aims to determine the effect of sodium hypochlorite disinfectant solution on the compressive strength of dental stones. The reduction in the compressive strength of type III gypsum mixed with sodium hypochlorite can be associated with a reduction in cohesion between crystals which may also affect the ability of the crystals to interlock, causing improper braiding and a reduction in cohesion between the crystals themselves and the presence of changes. which arises due to the formation of salts with low solubility when in large concentrations so that it can change the crystallization nucleus and consequently can affect the product properties of gypsum, this occurs due to the administration of sodium hypochlorite disinfectant solution with high concentrations so that it can significantly reduce the strength press on gypsum type III (dental stone) Sodium hypochlorite solution is not recommended to be used with the mixing technique because it can reduce the compressive strength of type III gypsum material (dental stone) and a good concentration of sodium hypochlorite is 3%.
