Establishment of an MRI‐Based Diagnostic Approach to Identify Critical Pulpal Inflammation Zones in a Rat Caries‐Derived Pulpitis Model

International Endodontic Journal, EarlyView.
ABSTRACT Aim To establish a magnetic resonance imaging (MRI)‐based diagnostic approach for identifying ‘critical pulpal inflammation’ zones in a rat model of caries‐derived pulpitis. Methodology Caries‐derived pulpitis was induced in the molars of Sprague–Dawley rats using the caries‐derived pulpitis model.

Microleakage study of three adhesive systems

Brazilian Dental Journal, 2004
The purpose of this in vitro study was to evaluate the efficacy of three hydrophilic dentin adhesive systems to reduce class II restoration microleakage. A total of 60 human molar teeth were used in which two box cavities were made on the distal and mesial surfaces, with a cervical margin in dentin. These cavities were randomly divided into 3 groups (n
