ABSTRACT
Objective: The Aim Of This Study Is To Evaluate The Effectiveness?of Two Herbal Extracts; Ginger And Rosemary Compared To 2% Sodium Fluoride On The Enamel Surface Of Extracted Human Premolars Regarding Surface Microhardness, Surface Topography And Mineral Content.

Materials and Methods: 120 First Premolars Were Collected And Divided Into 6 Groups. The Herbal Extracts Were Prepared To Merge Teeth In And The Demineralization Remineralization Cycle Start For 3 Weeks. The Evaluation Was Done By Vickers Micro-hardness Test And Environmental Scanning Electron Microscope. Statistical Analysis: Mean And Standard Deviation Of Microhardness And Minerals Content (continuous Data) After Testing The Normality Of Data. Normally Distributed Data Were Compared Of Different Groups Using One-way Analysis Of Variance. For All Tests P-value Of 0.05 Or Less Was Considered For Statistical Significance And Confidence Interval Was 95%. Result: The Mean Differences Between Control And Experimental Groups Was Not Statistically Significant. Ca Mass Has Significant Difference Between Ginger And NaF, Ginger And Artificial Saliva, While There Was No Statistical Significance In P Mass Percentage. Teeth Were Examined At Magnification Of 1000 With ESEM. Fig2 (a) Shows Normal Enamel Prisms? Ends With Few Surface Deposit And No Surface Enamel Roughness. Fig 2 (b) Shows Severe Surface Roughness Of The Enamel With No Surface Deposits. In Fig.2 (c), (d), (e) The Enamel Nearly Regained Its Original Surface With Normal Enamel Prisms? Ends And No Surface Roughness.

Conclusions: From This Laboratory Research, It Can Be Concluded That Ethanolic Ginger And Rosemary Have Comparable Remineralization Effect To Sodium Fluoride.
