How does Biodentine bond to tooth?

Biodentine interacts with hard tissues by micromechanical retention. Interactions of Biodentine with the dentin provided cues to understanding how this material provides a marginal sealing without any dentin surface preparation: no etching and no bonding.

How does MTA bond to dentin?

E.g. after placement of MTA on dentine, hydroxyapatite crystals nucleate and grow, filling the microscopic space between MTA and the dentine surface. Initially this seal is mechanical. Over time, the reaction between hydroxyapatite and dentine leads to a chemical bonding [19].

What is Biodentine used for in dentistry?

Biodentine is a material that, for the first time, allows a dentist to achieve biomimetic mineralization within the depths of a carious cavity. Biodentine has the potential to revolutionize the management of the deep carious cavity in operative dentistry, whether or not the pulp is exposed.”

Can Biodentine be used as root canal sealer?

The bond strength of Biodentine™ was better than that of MTA when used as a root-end filling material. Both materials were adversely affected by blood contamination (62).

Does composite bond to Biodentine?

The shear bonding strength of bonding composite to Biodentine was significantly reduced at the Biodentine primary setting phase or after prolonged time of exposure to the oral environment. The best time for placement of an overlying composite restoration is at 14 days.

Reasons for WHY BIODENTINE

How long does Biodentine take to set?

The powder is mixed with the liquid in a capsule in the triturator for 30 seconds. Once mixed, Biodentine™ sets in about 12 minutes. During the setting of the cement calcium hydroxide is formed.

How long does Biodentine last?

Biodentine™ can be left as a temporary filling for up to 6 months if the pulp requires monitoring. A direct composite or an inlay/onlay is then placed for enamel-like aesthetics and resistance.

What is Biodentine made of?

Biodentine is a two components material. The powder is mainly composed of Tricalcium silicates. It also contains Di-Calcium Silicate as a second core material and Calcium Carbonate and Oxide as filler. The powder contains Zirconium oxide as a radio-opacifier.

Is Biodentine soluble?

Biodentine showed acceptable solubility values at exposure times of 24 h, 3 days, and 10 days. Thereafter it demonstrated a marked increase in solubility; 1.07 (day 10 versus day 30) and 2.89 (day 30 versus day 60).

Is Biodentine antibacterial?

MTA, Biodentine, and Dycal showed significantly higher antibacterial activity than control in freshly mixed samples (P < 0.05).

Why is Biodentine better than Dycal?

The results of the present study showed that pulps that were treated with Biodentine were essentially free of inflammation and led to the formation of a good quality bridge which was more predictable, uniform, thick, continuous, and completely sealed the pulp tissue in comparison to Dycal.

How does mineral trioxide aggregate work?

The mineral trioxide aggregate (MTA) is a dental material with biocompatibility properties to oral and dental tissues. MTA was developed for dental root repair in endodontic treatment and it is formulated from commercial Portland cement, combined with bismuth oxide powder for radiopacity.

Can Biodentine be used for indirect pulp capping?

With its physical properties, compressive strength, elasticity and hardness, similarity to dentin, and reparative stimulation from calcium hydroxide ion release, Biodentine is an excellent choice for direct pulp capping, indirect pulp capping, pulpotomies, furcation repair and resorption repair.

Does MTA bond to tooth?

Nowadays, the material that offers the best sealing characteristic in the field of endodontic treatment is the mineral trioxide aggregate (MTA), nevertheless, this material necessities an adhesive bonding agent to perfectly join to the dental surface.

Is Biodentine same as MTA?

Biodentine is comparatively a new biomaterial claimed to have properties comparable to mineral trioxide aggregate (MTA). Biodentine and MTA are effectively used for direct pulp capping (DPC), and they are capable of regenerating relatively damaged pulp and formation of hard dentine bridge.

Does MTA dissolve?

Because MTA is alkaline in nature, it might interact with acids or chemicals and could disintegrate.

Is Biodentine radiopaque?

Radiopacity of Biodentine was 2.43±0.20 mmAl.

How does MTA set?

Mineral Trioxide Aggregate (MTA) is a powder that consists of hydrophilic particles that sets in the presence of moisture. Hydration of the powder results in a colloidal gel with a pH of 12.5 that solidifies to a hard structure.

Is Biodentine better than MTA?

Biodentine is found to be associated with high pH (12) and releases calcium and silicon ions which stimulates mineralization and create “mineral infiltration zone” along dentin-cement interface imparting a better seal. Caron G et al., have found that Biodentine exhibits superior sealing properties than MTA [24].

How do you use Biodentine for Apexification?

An apical plug of Biodentine of 5 mm thickness was placed against the matrix using pre-fitted hand pluggers. The remainder of canal was back-filled with thermoplasticized gutta-percha and access cavity was restored with composite resin followed by all-ceramic crown.

What is direct pulp capping?

DIRECT PULP CAPPING

The direct pulp cap, in which a material is placed directly over the exposed pulp tissue, has been suggested as a way to promote pulp healing and generate reparative dentin. If successful, this procedure precludes the need for more invasive, more extensive and more expensive treatment.

How long does a pulpotomy take?

A pulpotomy takes about 30 minutes to complete from start to finish. A member of the dental team will first numb the area to ensure that your child won't feel any pain or discomfort during the procedure. The endodontist will remove the damaged pulp from the tooth before sterilizing the area to remove all the infection.

What is Formocresol used for?

Formocresol is a mixture consisting of formalin, cresol and glycerine used in dentistry. It is used for vital pulpotomy of primary teeth and as a temporary intracanal medicament during root canal therapy.

What is BioAggregate?

Objectives: BioAggregate™ is a novel material introduced for use as a root-end filling material. It is tricalcium silicate-based, free of aluminium and uses tantalum oxide as radiopacifier. BioAggregate contains additives to enhance the material performance.
