• Natural Formulation: Based on d-Limonene (extracted from orange oil), making it biocompatible and tissue-friendly.

   

• Non-Hazardous: Completely free from Chloroform and Trichloroethylene, posing no carcinogenic risk to the dentist or patient.

   

• Low Volatility: Evaporates slowly compared to traditional solvents, ensuring a longer working time and less material waste.

   

• Gentle on Tissues: Does not cause irritation to the oral mucosa or periapical tissue when used as directed.

   

• Pleasant Aroma: Features a mild, citrus scent that improves the clinical environment for the patient.

Carvene is a specialized d-Limonene based solvent used in endodontic retreatment. It is designed to safely and efficiently soften and dissolve gutta percha and various root canal sealing materials (like Zinc Oxide-Eugenol cements) to facilitate their removal from the root canal. Unlike traditional solvents like Chloroform or Trichloroethylene, Carvene is a safer, non-carcinogenic alternative derived from natural orange oil.

The product is typically supplied in a professional kit containing:

• 1 x 10ml Amber Glass Bottle (to protect the light-sensitive formula).

   

• 1 x Precision Dispensing Dropper.

   

• 1 x Instruction for Use (IFU) Manual.

• Application: Using the provided dropper, place 1–2 drops of Carvene directly into the root canal or onto a cotton pellet.

   

• Softening: Allow the solvent to sit for a few moments to soften the gutta percha.

   

  • Note: Some protocols suggest placing a soaked cotton pellet and covering it with temporary cement for 48 hours in difficult cases.

• Removal: Use an endodontic file or probe to remove the softened material.

   

• Repeat: If the filling material is thick or dry, re-apply the solvent as needed until the canal is completely clean.

   

• Clean-up: Carvene can also be used to clean and disinfect endodontic instruments after the procedure.

• Warranty: The manufacturer warrants the product against manufacturing defects. This usually covers the chemical integrity of the liquid but excludes physical damage to the bottle after purchase or issues caused by improper storage.

   

• Safety Warning: Highly flammable. Keep away from heat and open flames. Avoid prolonged skin contact as it may cause sensitization in some individuals.

   

• Contraindications: Do not use on patients with a known allergy to orange oil or d-Limonene. Do not extend the material beyond the root apex.
