A similar role is played by the dentin bridge
, which forms after odontotropic medications have been applied to the dental pulp exposure site.
2,5-6 However, CaOH displays partial dentin bridge
formation with tunnel defects resulting in pulp capping failure.
9, 10) In addition, in contact with pulp tissue, the material can stimulate dentin bridge formation.
After 6 weeks, most premolars showed formation of full dentin bridge, with absence of pulp inflammatory response; no significant differences were found between BiodentineTM and MTA during the observation period.
2]) is successfully used in direct dental pulp capping as it stimulates pulp repair and isolates the tissue from aggressive agents through dentin bridge formation.
Furthermore, this study also aimed to evaluate the action of pastes A and B in dentin bridge formation in adult dogs following experimental dental pulp exposition (Part 2).
Indications for its use include pulp capping to induce dentin bridge
formation (1), (2), (3), fostering apical closure of permanent teeth (1), (2), (4), (5), (6), promoting resolution of periapical and resorptive lesions (3), (4), (7), (8) and as an inter-appointment disinfectant in the root canal space (3), (6), (8), (9), (10).
The dentin bridge
in the BC group was similar to that in the Ca[(OH).
To date, researchers have been unable to identify a reliable non-resorbable bioactive pulp capping material that consistently stimulates cellular repair mechanisms, seals the dentin and promotes formation of a biologically stable reparative dentin bridge.
Although calcium hydroxide is also used as a direct pulp capping material it is unstable and can degrade and dissolve under restorations, allowing potential ingress of microorganisms and subsequent bacterial contamination through tunnel defects in the dentin bridge.
The ideal material for direct pulp capping must be able to control infection, adhere to dentin to prevent microleakage, offer simple clinical management, and promote dentin bridge formation.
34) The basic pH of CH (pH 12) makes it a good bactericidal agent, and it also allows the formation of a dentin bridge when directly placed on the pulp.
