Histological evaluation of a self-priming etchant adhesive system.

Vital dentin is an extension of certain pulpal tissues, presenting the first line of defense against patient hypersensitivity and the long-term bacterial microleakage that can lead to recurrent caries and pulp inflammation. High-speed cavity preparation and forced air-drying of vital dentin causes the displacement of cells into vital dentinal tubules. However, after restoration, pulps recover and deposit reparative dentin deposition within 2 weeks.

Identification of hierarchical factors to guide clinical decision making for successful long-term pulp capping.

Objective: Clinicians have few quantitative studies that rank the in vivo pulp capping effects of commonly used restorative materials. These factors were investigated to provide guidance to clinicians.

Method And Materials: One hundred sixty-one standardized pulp-exposed cavities were prepared in nonhuman primate teeth.

Hierarchy of pulp capping and repair activities responsible for dentin bridge formation.

Purpose: The importance of pulp capping variables which mediate pulp repair activities and dentin bridge formation following pulp exposure are not well understood. Consequently, the aim of this study was to investigate the effects of pulp capping variables on tertiary dentin bridge formation.

Materials And Methods: Calcium hydroxide [Ca(OH)2], resin-modified glass-ionomer (RMGI) and resin-based composite (RBC) were used to restore pulp exposures prepared in 161 nonhuman primate teeth, according to ISO usage guidelines.

Analysis of pulpal reactions to restorative procedures, materials, pulp capping, and future therapies.

Every year, despite the effectiveness of preventive dentistry and dental health care, 290 million fillings are placed each year in the United States; two-thirds of these involve the replacement of failed restorations. Improvements in the success of restorative treatments may be possible if caries management strategies, selection of restorative materials, and their proper use to avoid post-operative complications were investigated from a biological perspective. Consequently, this review will examine pulp injury and healing reactions to different restorative variables.

Bacterial microleakage and pulp inflammation associated with various restorative materials.

Objectives: Many restorative materials are claimed to be successful in preventing bacterial microleakage and minimizing pulp inflammation. However, information regarding the in vivo performance of materials in comparison with each other is limited. The aim of this study was to evaluate and compare the pulp response of nine restorative materials when placed in non-exposed monkey cavities.

Preserving the vital pulp in operative dentistry: 4. Factors influencing successful pulp capping.

The sequence of factors that mediate pulp inflammation and necrosis are unclear, and controversy surrounds the effects of different pulp capping materials on exposed pulps. Clinicians have few quantitative studies that rank the in vivo pulp capping effects of commonly used restorative materials.

An in vivo evaluation of hemorrhage control using sodium hypochlorite and direct capping with a one- or two-component adhesive system in exposed nonhuman primate pulps.

Objective: This study evaluated the biologic ability of sodium hypochlorite to control hemorrhage via chemical amputation of the coagulum, to remove dentin chips, to assist healing, and to facilitate formation of a dentinal bridge under two adhesive systems.

Method And Materials: Ninety Class V cavities with mechanical pulpal exposures were placed in the teeth of five adult monkeys and histologically observed. All exposures were prepared with a No.
