Method: 40 extracted teeth were cleaned and shaped. A 3 mm section of each root was taken at the middle-third level and embedded in cold cure acrylic resin. Vicker’s Hardness Test was used to measure the microhardness of each specimen prior to exposure with the respective irrigants and Root anal Mediaments. Each group consisted of 20 samples. Group A samples were immersed in NaOCl for 15 minutes followed by an application of a paste of calcium hydroxide for 48 hours. Group B samples were immersed in Morinda citrifolia juice for 15 minutes followed by an application of a paste of Morinda citrifolia for 48 hours. After 48 hours the microhardness of the specimens was measured again, using the same test.
Results: The reduction in the hardness of the root dentin was found to be lesser when they were immersed in Morinda citrifolia, as compared to immersion in a combination of NaOCl and Ca(OH)2.
Conclusion: When used as a …show more content…
The percentage change (decrease) of Microhardness in HV (50g load) from initial to final, after 48 hours, in group A is 24.17%. And the percentage change (decrease) of Microhardness in HV (50g load) from initial to final, after 48 hours, in the group where Morinda is used is 10.88%. According to the tests conducted, the reduction in the hardness of the root dentin of the tooth samples was found to be lesser in Group B, as compared to Group A (Graph
