This study was conducted to observe the formation and nature of tunnel defects in dentin bridges, assess the nature of the associated soft tissue elements, and note the relationship of pulp inflammation and necrosis associated with these defects. A total of 235 teeth with class 5 cavity preparation exposures were randomly distributed throughout the dentitions of 14 adult rhesus monkeys. Each pulp was exposed and left open to the oral microflora at one of four time intervals, flushed with saline… Expand
The incidence of pulp healing defects with direct capping materials.
The capping materials were associated with varying levels of pulp healing defects, including tunnel defects, and pulpal inflammatory cell activity (P= 0.0073) and bacterial leakage, and the area of dentin bridge were not influenced by capping material. Expand
Experimental Study of Pulp Capping Using Xenogenic Demineralized Dentin Paste
This study aimed to compare the effectiveness of demineralized dentin paste (DDP) with mineral trioxide aggregates(MTA) as a direct pulp capping material. Artificial Class V cavity was prepared toExpand
A histopathologic study of direct pulp-capping with adhesive resins.
The results of direct pulp-capping with a dentinal adhesive and composite resin appear promising but further in vivo studies are recommended. Expand
Short term human primary pulpal response after direct pulp capping with fourth-generation dentin adhesives.
Based on the conditions of the present study, direct pulp capping with dentin bonding agents following the total-etch technique in primary teeth can not be recommended. Expand
A Histopathological Study of Direct Pulp Capping with Adhesive Resins
Statement of Problem: Recently, it has been proposed that different adhesive materials can be used for direct pulp capping. Previous studies have demonstrated that multi steps dentin adhesives couldExpand
Dentinogenic responses after direct pulp capping of miniature swine teeth with Biodentine.
The application of both calcium silicate-based materials in direct contact with the mechanically exposed pulp of healthy miniature swine teeth led to pulp repair with complete hard tissue bridge formation. Expand
Pulp tissue reactions to a dentin bonding agent as a direct capping agent.
Investigation of the response of human pulp tissue to a dentin bonding agent, Scotchbond Multi-Purpose Plus (SMPP), in exposed class V cavities found SMPP may cause inflammatory changes when applied directly to exposed pulp tissue. Expand

Bonding agent is supposed to seal the exposure site, and the remaining bonding agent on the cavities was effective as the barrier in the dentin bridges after bacterial challenges. Expand
Effect of a Calcium-silicate-based Restorative Cement on Pulp Repair
Evaluating the capacity of a new calcium-silicate-based restorative cement to induce pulp healing in a rat pulp injury model suggests that the evaluated cement can be used for direct pulp-capping. Expand
Evaluation of mineral trioxide aggregate and calcium hydroxide cement as pulp-capping agents in human teeth.
Although the pulp healing with calcium hydroxide was slower than that of MTA, both materials were successful for pulp capping in human teeth and a lower response of CH30 was observed for the dentin bridge formation when compared with MTA30 and MTA60 groups. Expand
