Pulp capping procedures is often into the pulp may have direct influence on the performed when a pulpal exposure occurs due to inflammatory response. In cases of direct pulp capping, a continuous hard tissue barrier determined by direct clinical ex-amination and a positive response to electric pulp tester stimulation. Direct pulp capping is defined as a wound dressing of the exposed clinically normal pulp with the absence of signs and symptoms of severe pulpal disease. Direct Pulp Capping: Here the protective dressing is placed directly above an exposed pulp. prior to placing a restoration is termed as a direct pulp capping. The laser irradiation also increased HSP47 expression but not collagen gene expression. EMD is enamel matrix derivative secreted from Hertwig’s epithelial root sheath during, porcine tooth development.

The response of the dentin–pulp complex in rat teeth was investigated after direct capping with biodentine with or without bone marrow‐derived stem cells (BMDSCs). The mineralization of the collagen starts with dystrophic calcification of both the zone of firm necrosis and the degenerated cells in the adjacent tissue, leading to deposition of mineral in the newly-formed collagen. In direct capping with this paste showed no pulp degeneration and, compared the proliferation and stem cell marker of SHED, DSPCs and Bone Marrow Derived. Application of anti-stimuli and/or anti-inflammatory agents in combination with the direct pulp capping materials/agents will be affective. The expression levels of collagen type I and HSP47, collagen-binding stress protein, were analysed by real-time PCR. Bjorndal, L. et al. Direct puip capping The cleaner tooth surface could also conceivably allow better adaptation of the restorative material and hence reduce microleakage (37).
