Biodentine Flashcards
What is Biodentine?
A new class of dental material with excellent biocompatibility and good mechanical properties
Developed by Septodont using Active Biosilicate Technology
List the applications of Biodentine.
- Dentine substitute
- Direct pulp capping material
- Indirect pulp capping material
- Temporary filling
- Endodontic repair material (perforation, apexification, resorption)
These applications highlight its versatility in dental procedures.
What are the advantages of using Biodentine?
- Assists in the remineralization of dentine
- Preserves pulp vitality and promotes pulp healing
- Replaces natural dentine with similar mechanical properties
- Better handling and manipulation characteristics
- Reduced setting time
These advantages make Biodentine a favorable option in dental treatments.
What are the disadvantages of Biodentine?
- Not as stable as composite material
- Only suitable as temporary filling materials
- Inevitable waste of material due to small quantities used for endodontic applications
These factors limit its use in permanent restorations.
What are the mechanical properties of Biodentine?
- Adhesion: micromechanical anchoring and ion exchange
- Density: increased due to hydrosoluble polymer
- Porosity: lower porosity results in better mechanical strength
- Radiopacity: conferred by zirconium oxide
- Compressive strength: improves to 300 MPa in about a month
- Microhardness: reaches similar range as natural dentine in about a month
These properties are critical for its performance as a dental material.
What contributes to the antibacterial properties of Biodentine?
The resulting Ca(OH)2 which creates a high pH (12)
High pH is associated with antibacterial activity.
True or False: Biodentine is a permanent enamel replacement material.
False
Biodentine is not suitable for permanent restoration due to its stability issues.
Fill in the blank: Biodentine has the ability to release _______ and hydroxyl ions.
calcium
This ion release assists in dentine mineralization and dentine bridge formation.
What is the working time for Biodentine?
Up to 6 minutes
This is significantly shorter compared to traditional calcium silicate materials.
Describe the setting reaction of Biodentine.
Calcium silicate interacts with water leading to the formation of a hydrated calcium silicate gel and calcium hydroxide
This reaction is crucial for the hardening and sealing properties of Biodentine.
What are the physical, chemical, and biological properties of Biodentine?
Well tolerated, promotes mineralization, biocompatible, and bioactive with regenerative potential
These properties highlight the effectiveness of Biodentine in clinical applications.
What is the final set time for Biodentine?
Around 10-12 minutes
This rapid setting time is advantageous for clinical efficiency.
List the indications for using Biodentine.
- Direct pulp capping
- Indirect pulp capping
- Temporary fillings
- Endodontic repairs
These indications showcase its versatility in various dental situations.
What is the role of the hydrating gel formed during the setting of Biodentine?
It is relatively impermeable to water and slows down further reactions
This contributes to the good sealing properties of Biodentine.
