BACTERIAL LEAKAGE OF BIOCERAMICS PULP DRESSING MATERIALS: A REVIEW OF LITERATURE

Abstract

Vital pulp therapies are mostly recommended for primary teeth with deep or extensive carious lesions with reversible pulpitis. Recently, various dressing materials in pulp management have been introduced. These materials each have their own recommended concentration and potentially bioactive ingredients, leading to a claim of additional healing. As more pulpotomy dressing agents are introduced in treating pulp exposure caused by caries or trauma, different outcomes of each treatment should be evaluated. CH and MTA are among the commonly used medicament for coronal pulpotomy. More bioactive materials of pulpotomy-dressing agents intrigued clinicians, s.uch as CEM (calcium-enriched cement) and modified calcium silicate-based materials (MTA, Biodentine) with the claim of additional benefits of one material over anotherbenefits. Microleakage is the clinically undetectable passage of fluids, bacteria, ions or molecules between a tooth and the filling or restorative material. Microleakage typically occurs in two-level: micron-level leakage, also known as bacterial leakage and submicron-level leakage, which is called nano leakage.
