What are the main types of endodontic sealers available on the market?
The main types of endodontic sealers are zinc oxide eugenol-based sealers, calcium hydroxide-based sealers, glass ionomer-based sealers, resin-based sealers, bioceramic-based sealers, and silicone-based sealers. Each type has specific properties and applications in root canal therapy.
What is the role of endodontic sealers in root canal therapy?
Endodontic sealers fill gaps between the root canal walls and gutta-percha, creating a hermetic seal to prevent microbial leakage and re-infection. They enhance the physical and microbial properties of root canal obturation, promoting healing and longevity of the endodontic treatment.
What are the key factors to consider when choosing an endodontic sealer?
When choosing an endodontic sealer, consider biocompatibility, sealing ability, ease of use, radiopacity, setting time, and antimicrobial properties. Additionally, ensure compatibility with obturation materials and techniques to achieve optimal clinical outcomes.
How long do endodontic sealers last once applied in a root canal?
Endodontic sealers are designed to last the lifetime of a successful root canal treatment, generally remaining intact as long as the tooth is not compromised by further decay or structural damage. An effective root canal treatment with proper sealing can potentially last for many years, often decades, with good oral hygiene.
Are there any common side effects or reactions associated with the use of endodontic sealers?
Common side effects of endodontic sealers may include mild inflammatory reactions or allergic responses in sensitive individuals. Some sealers may cause tissue irritation if overfilled beyond the root canal. In rare cases, systemic hypersensitivity reactions have been reported. It's crucial to follow proper application guidelines to minimize these risks.
