| Summary: | Background: Calcium hydroxide is a gold standard for root canal sealing material. However, there are many defects
in calcium hydroxide that have prompted many researchers to look for alternative materials, including natural origin
ingredients. Red pine (Pinus densiflora) is often used in dentistry for its antioxidant and antibacterial properties. The
mixture of calcium hydroxide and red pine has never been achieved before. One of the criteria for material sealing is
that the channel should be fully sealed with high flow ability and low viscosity. Therefore, this research is performed to
analyze the viscosity value of the mixture of calcium hydroxide and red pine (Pinus densiflora). Purpose: Knowing the
difference in viscosity of the combination of calcium hydroxide and red pine with a ratio of 1:1, 1:1.5, and 1:2. Methods:
This study used four treatment groups, with each group consisting of 8 replications. Group 1 was a combination of
calcium hydroxide and red pine with a 1: 1, group 2 the ratio was 1: 1.5, group 3 had the ratio 1: 2, and the positive
control group used calcium hydroxide and a sterile aquadest. Calcium hydroxide in powder form and an extract of red
pine in liquid form are mixed according to the ratio. The viscosity value is measured using a viscosity tester, namely the
Brookfield Viscometer. Results: The control group had a lower viscosity than group 3, group 3, and group 2 than group
1. Conclusion: Combination of calcium hydroxide and red pine with a ratio of 1:2, the lowest viscosity was obtained
compared to the ratio of 1: 1 and 1: 1.5. |
