Abstract
Background: Failure of endodontic treatment is caused by 60% of poor obturation. Sealers have an important role in the obturation process, that is filling the root canals and the space between the dentin and the core material. Sealers must have low viscosity so that they can flow easily and fill the entire root canal space so can form a good seal and have physical properties that are not easily soluble to oral fluids to prevent sealer degradation which can cause gaps during filling and become a medium for bacterial proliferation. Red pine extract is a natural ingredient that contain flavonoid and phenolic acid that are effective in reducing the viscosity and solubility of the sealer combination ZnO with red pine. Purpose: To determine the effectiveness of sealer combination ZnO with red pine in reducing viscosity and solubility. Methods: Red pine (Pinus densilora) extract with a concentration of 100% was diluted to a concentration of 0.78% using the dilution formula M1.VI = M2.V2. Viscosity test was done by mixing ZnO with red pine extract 0.78% 1: 1 and calcium hydroxide (Ca(OH)2) with 1: 1 sterile aquadest as a comparison, then each sample was measured for viscosity using a brookfield viscometer. The solubility test was carried out by placing the paste on a disc with a diameter of 15 mm x 3 mm and then being set and immersed in distilled water for 24 hours then the percentage of solubility was calculated. Results: The viscosity value of combination ZnO with red pine is 19.89 Pa.s and the solubility is 0.0075%, while Ca(OH)2 with sterile aquadest had a viscosity of 23.32 Pa.s and a solubility is 0.029%. Conclusion: The combination of ZnO with red pine is effective in reducing the viscosity and solubility of the combination sealer. The viscosity and solubility of the combined sealer is lower than Ca(OH)2 with sterile aquadest.
Highlights
Root canal treatment is a treatment of dental conservation that aims to maintain damaged teeth to be biologically accepted by the surrounding tissue without any signs of pathological abnormalities and still functional in the oral cavity.[12]
This study consisted of two units of the research group, namely treatment group I (the combination of zinc oxide (ZnO) - red pine (Pinus densiflora) with a ratio of 1: 1), while treatment group II was the comparison, with each unit the research group consisted of 18 replications
As for the solubility, the results showed that the lowest solubility value was owned by the ZnO + Red Pine group with a value of 0.0075%
Summary
Root canal treatment is a treatment of dental conservation that aims to maintain damaged teeth to be biologically accepted by the surrounding tissue without any signs of pathological abnormalities and still functional in the oral cavity.[12]. Sealers have an essential role in the obturation process by filling the space between the dentin and the core material.[3] There is still no ideal sealer. Sealers have an important role in the obturation process, that is filling the root canals and the space between the dentin and the core material. Purpose: To determine the effectiveness of sealer combination ZnO with red pine in reducing viscosity and solubility. Results: The viscosity value of combination ZnO with red pine is 19.89 Pa.s and the solubility is 0.0075%, while Ca(OH)[2] with sterile aquadest had a viscosity of 23.32 Pa.s and a solubility is 0.029%. Conclusion: The combination of ZnO with red pine is effective in reducing the viscosity and solubility of the combination sealer. The viscosity and solubility of the combined sealer is lower than Ca(OH)[2] with sterile aquadest
