In vitro evaluation of the effect of deproteinization on the marginal leakage of resin restorations using three bonding agents

Dental Research Journal, 2012
Background: The perfect sealing of the tooth/restoration interface is important to prevent bacteria penetration that may lead to secondary caries and also, when dentin is involved, prevent excessive fluid movement in the dentinal tubules that may cause ...

Modification of dentin surface to enamel-like structure: A potential strategy for improving dentin bonding durability, desensitizing and self-repairing

Dental Hypotheses, 2014
Introduction: Current theories of dentin bonding are based on the concept of "hybrid layer". However, the histological complexity of dentin, as well as the vulnerability of the hybrid layer, goes against the long-term effect of dentin bonding.

Cellular porosity in dentin exhibits complex network characteristics with spatio-temporal fluctuations.

PLoS ONE
According to the current hydrodynamic theory, teeth sensitivity is mediated by odontoblast cell processes which can be activated by fluid flow in the pericellular space of bulk dentin.

Matrix Metalloproteinase-9 (MMP-9) Levels in Dentinal Fluid as a Diagnostic Biomarker for Irreversible Pulpitis

Objective: Pulpitis is an inflammatory condition of the dental pulp. The inflammatory status can be accurately assessed by histological examination. Biomarkers, such as matrix metalloproteinases (MMPs), are effective indicators of inflammation severity ...
