microlekkage
Microlekkage (also spelled microleakage in English) refers to the diffusion of fluids, bacteria, enzymes, or ions through microscopic gaps at the interface between a dental restoration and tooth structure, or through defects within a restorative material. The term is most commonly used in dentistry to describe pathways that allow oral substances to penetrate despite an apparently intact restoration.
Causes include polymerization shrinkage of resin-based materials, thermal cycling in the oral environment, occlusal loading, and
Consequences can range from dentin hypersensitivity and marginal discoloration to secondary caries and pulpal irritation. Over
Measurement and evaluation of microlekkage are typically conducted in laboratory settings. Common methods include dye penetration
Prevention focuses on meticulous placement techniques, effective isolation, and appropriate material selection. Using bonding systems with
