An inflammatory response occurs in the pulp tissue following the application of dental materials due to their chemical properties and/or a secondary bacterial irritation. Recently, a new line of composite resin products with reported improved esthetic qualities was designed to allow an intimate adherence with the dentin. This intense bonding could prevent bacterial penetration and marginal discoloration of these restorations. In addition, this method allows prevention of excessive removal of hard tissue. The present study examines pulpal reaction to capping with P-10 composite resin (Dental Products, USA) in rats. Histological examination did not reveal any inflammatory reaction in the nonexposed pulps. Direct pulp capping with P-10 induced formation of reparative dentin bridges.

UI	MeSH Term	Description	Entries
D011671	Pulpitis	Inflammation of the DENTAL PULP, usually due to bacterial infection in dental caries, tooth fracture, or other conditions causing exposure of the pulp to bacterial invasion. Chemical irritants, thermal factors, hyperemic changes, and other factors may also cause pulpitis.

D003782	Dental Pulp	A richly vascularized and innervated connective tissue of mesodermal origin, contained in the central cavity of a tooth and delimited by the dentin, and having formative, nutritive, sensory, and protective functions.

D003785	Dental Pulp Capping	Application of a protective agent to an exposed pulp (direct capping) or the remaining thin layer of dentin over a nearly exposed pulp (indirect capping) in order to allow the pulp to recover and maintain its normal vitality and function.
