Agentes quelantes

Chelating agents are chemical compounds that bind to metal ions, facilitating the removal of inorganic material from the root canal system. In endodontics, they are primarily used to soften dentin, remove smear layers, and improve the penetration of irrigation solutions into the dentinal tubules.

WholeDent offers high-quality chelating agents like DSI EDTA 17% Solution Liquid (100ml and 15ml), which efficiently remove calcified debris, and Spident SoftPrep® Root Canal Preparation EDTA Cream, which provides excellent lubrication for root canal instrumentation. These agents enhance the cleaning efficiency and reduce procedural difficulties by making the dentin more permeable, ensuring superior canal shaping and disinfection.

Chelating agents come in both liquid and cream formulations, each serving specific clinical needs:

• Liquid Chelating Agents (e.g., DSI EDTA 17% Solution Liquid 100ml & 15ml): These solutions are ideal for thorough dentin demineralization and smear layer removal. They are often used as an irrigation solution in combination with sodium hypochlorite to maximize bacterial elimination.
  
  
• Cream-Based Chelating Agents (e.g., DSI Apexcream EDTA 18% & Spident SoftPrep® Root Canal Preparation EDTA Cream): These formulations provide additional lubrication, reducing instrument binding and increasing the efficiency of root canal shaping. Cream-based EDTA is particularly beneficial for narrow or curved canals where smooth instrumentation is critical.
  
  

Both forms are crucial in different stages of root canal treatment, ensuring a comprehensive cleaning and shaping process.

EDTA (Ethylenediaminetetraacetic acid) plays a vital role in root canal irrigation by removing the smear layer—a layer of debris that forms on canal walls during instrumentation. Its key benefits include:

• Decalcification of Dentin: Chelating agents like DSI EDTA 17% Solution dissolve the inorganic components of dentin, making it easier for disinfecting agents like sodium hypochlorite to penetrate deeper.
• Lubrication for File Navigation: Spident SoftPrep® Root Canal Preparation EDTA Cream aids in smooth file movement, minimizing the risk of ledging or perforations.
• Enhanced Disinfection: By opening the dentinal tubules, EDTA allows antimicrobial solutions to reach deeper bacterial colonies.

Using a combination of EDTA and NaOCl (sodium hypochlorite) provides superior cleaning and microbial control, ensuring a more successful root canal treatment.

To achieve the best outcomes when using chelating agents in root canal procedures, follow these guidelines:

1. Irrigation with EDTA: Use DSI EDTA 17% Solution as a final irrigant after shaping the canal to remove the smear layer and enhance disinfection.
2. Lubrication with EDTA Cream: Apply DSI Apexcream EDTA 18% or Spident SoftPrep® during mechanical instrumentation to prevent file breakage and facilitate canal navigation.
3. Rinse with Sodium Hypochlorite: Alternate with NaOCl solutions to maximize the antibacterial effect.
4. Final Rinse: Conclude with distilled water or a mild disinfectant to remove residual EDTA before obturation.

Proper application ensures effective canal preparation, minimizing post-treatment complications and increasing the success rate of endodontic therapy.
