The formation of Dentin Bridge of good quality preventing any bacterial infiltration and promoting the closure of the breach was observed.
* O: the main outcomes were formation of Dentin Bridge and conservation of pulp vitality.
Mizuno & Banzai (74) studied the effect of calcium ions on the dental pulp cells and the mechanism of dentin bridge formation by calcium hydroxide.
A similar role is played by the dentin bridge, which forms after odontotropic medications have been applied to the dental pulp exposure site.
The placement of biocompatible materials on pulp injury site defends the pulp-dentin complex against chemical insult by operative procedures, material toxicity and bacterial penetration due to microleakage.1-3 Calcium Hydroxide (CaOH) has been regarded as a preference material in situations where vital pulp therapy is indicated.2,5-6 However, CaOH displays partial dentin bridge formation with tunnel defects resulting in pulp capping failure.2 Mineral Trioxide Aggregate (MTA) has provoked significant attention being a direct pulp capping material in present-day dentistry.
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.
(Ca[(OH).sub.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.
Six months later, an intraoral examination showed no abnormalities in the gingiva of the mandibular right second premolar (Figure 3(a)), while an X-ray photographic evaluation showed formation of a dentin bridge in the mandibular right second premolar (Figures 3(b) and 3(c)).
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).
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. Success rates with direct pulp capping in a carious field varied depending on the technique and materials used.
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.
