Metabase, Metapex, and Vitapex are all materials used in dentistry, specifically for root canal fillings in primary (baby) teeth. Here's a breakdown of their key differences:
* Metabase:
* Composition: Calcium hydroxide-based material.
* Purpose: Primarily used for pulpotomies (removal of the coronal portion of the pulp) in primary teeth.
* Mechanism: Promotes the formation of a calcific bridge, which helps to seal the root canal and prevent infection.
* Metapex:
* Composition: Premixed paste of calcium hydroxide and iodoform and zinc oxide oygenol
* Purpose: Primarily used for root canal fillings in primary teeth.
* Mechanism: Combines the antibacterial properties of iodoform with the bridge-forming ability of calcium hydroxide.
* Vitapex:
* Composition: Premixed paste of calcium hydroxide and iodoform.
* Purpose: Primarily used for root canal fillings in primary teeth.
* Mechanism: Similar to Metapex, it combines antibacterial and bridge-forming properties.
