Aim:To evaluate and compare the effect of QMix, Tea tree oil, Tamarindus indica, Green tea extract and 17% EDTA on root dentine micro-hardness.

Methodology: Sixty freshly extracted human single rooted premolars were selected and divided into six groups and subjected to various treatments as follows: Group 1-Q mix, Group 2-Tea tree oil, Group 3 - 5% Tamarindus indica, Group 4 - 5% Green tea, Group 5 - 17% EDTA and Control group-normal saline. Each group was immersed in their solutions for 5 minutes and then subjected to Vickers micro-hardness testing.

Statistical analysis: Results were subjected to one way Anova and Tukey’s test.

Results: Maximum reduction in micro-hardness was seen in the EDTA group, followed by Qmix and then Tamarindus indica groups. Tea tree oil group and Green tea groups did not show significant reduction in microhardness. Least reduction was seen in the control group saline.

Conclusion: EDTA induced maximum reduction in root dentin microhardness, followed by Qmix and Tamarindus indica. There was no significant reduction by Green tea, Tea tree oil and saline (p > 0.05) Tamarindus indica caused significantly less reduction than EDTA (p < 0.001).
