The Gentle Brush method effectively removes calcium hydroxide from root canals, outperforming other files. Combining it with ethylene-diamine-tetra-acetic acid (EDTA) offers superior cleaning for better endodontic treatment outcomes.
Area of Science:
- Endodontics
- Dental Materials Science
Background:
- Effective removal of intracanal medications is vital for successful endodontic therapy.
- Residual calcium hydroxide can negatively impact sealer adhesion and treatment success.
Purpose of the Study:
- To compare the efficacy of different methods for removing calcium hydroxide from root canal walls.
- To evaluate cleaning effectiveness in coronal, middle, and apical regions.
Main Methods:
- An in vitro randomized trial involving 108 extracted teeth.
- Calcium hydroxide placement followed by various cleaning protocols using Gentle Brush, Gentlefile, or master apical files with EDTA or sodium hypochlorite.
- Stereomicroscopic analysis and Digimizer software for quantifying residual calcium.
Main Results:
- The Gentle Brush method demonstrated significantly higher efficacy in calcium hydroxide removal (p<0.01).
- Ethylene-diamine-tetra-acetic acid (EDTA) was significantly more effective than sodium hypochlorite (p<0.05).
Conclusions:
- A combination of the Gentle Brush and EDTA is the most effective protocol for calcium hydroxide removal.
- Optimizing canal cleaning techniques is crucial for enhancing endodontic treatment quality.

Effects of EDTA on End-Point Detection Methods
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a...
EDTA: Direct, Back-, and Displacement Titration
Direct titration involves buffering the metal ion solution to the desired pH and directly titrating with standard EDTA until the endpoint. The optimum pH ensures a large conditional formation constant of metal−EDTA and visibility of the free indicator color in the solution. In addition, auxiliary complexing reagents are used to prevent the precipitation of metal hydroxides...
