ABSTRACT
Objective: The Purpose Of This Study Was To Evaluate The Effect Of Herbal Irrigation (Green Tea Extract And Garlic Extract) On Micro Hardness Of Root Canal Dentin.

Materials and Methods: Twenty Human Single Rooted Mandibular Premolars Were Decoronated, The Root Length Was Determined. Instrumentation Was Done Using Revo S Rotary Files, Samples Were Divided Into Four Groups; Two Experimental Groups Of 7n Each (n = 7) And Two Control Groups (positive And Negative) Of 3 In Each (n = 3) According To The Irrigants Used During And After Instrumentation. Group I: Green Tea Extract, Group II: Garlic Extract, Group III: Sodium Hypochlorite 5.25% And EDTA 17% (positive Control), Group IV: Distilled Water (negative Control). The Roots Were Split Longitudinally And Prepared To Measure Dentin Microhardness. Quantitative Data Presented By Mean And SD,�Friedman Test, Mannwhiteny Test And Kruskal Wall Is Test Were Used.

Results: The Highest Microhardness Values Were Recorded For Distilled Water Followed By Green Tea And Garlic Extracts Respectively And The Lowest Values Were Given By Sodium Hypochlorite With EDTA. There Was Statistically Non-significant Difference Between Garlic Extract And Sodium Hypochlorite With EDTA On Microhardness Of The Root Canal.

Conclusions: It Was Concluded That The Use Of Herbal Extracts As Irrigant Regimen Will Not Hamper The Root Dentin Microhardness When Compared With Conventional Irrigations Regimens.
