The purpose of this study was to assess the histological appearance of the pulp of human primary incisors extracted because of deep, unrestorable caries, and to determine how clinical pulp exposures affected the histological status of the pulp compared to nonexposures. Caries was removed carefully from all teeth after fixation; 24 incisors had pulp exposures, and 29 teeth had no pulp exposures....

Regenerative endodontics aims to replace inflamed/necrotic pulp tissues with regenerated pulp-like tissues to revitalize teeth and improve life quality. Pulp revascularization case reports, which showed successful clinical and radiographic outcomes, indicated the possible clinical application of pulp regeneration via cell homing strategy. From a clinical point of view, functional pulp-like tiss...

introduction: the aim of this study was to determine the histologic effect of low level laser therapy (lllt) with or without the use of mineral trioxide aggregate (mta) on exposed pulp tissues of dogs. methods: twenty-five premolar teeth in three healthy mature dogs were randomly divided into five groups. in group 1, the pulp tissue was capped with mta. in groups 2 and 3, before capping with mt...

i ntroduction: the aim of this study was to evaluate the clinical and histological status of the pulp in sound human premolars after direct pulp capping (dpc) with four different dpc methods/materials. methods and materials: this study was conducted on eight volunteers who had to extract four first premolars due to orthodontic treatment. subsequent to tooth isolation, standardized class i occlu...

Formocresol pulpotomy (FP) in the United States is most frequently used to treat asymptomatic caries near the pulp in primary teeth. Indirect pulp therapy (IPT) is also indicated and has a significantly higher long-term success. Pulpotomy is thought to be indicated for primary teeth with carious pulp exposures, but research shows the majority of such teeth are nonvital or questionable for treat...

Interactions between ingrowing nerve fibers and their target tissues form the basis for functional connectivity with the central nervous system. Studies of the developing dental pulp innervation by nerve fibers from the trigeminal ganglion is an excellent example of nerve-target tissue interactions and will allow specific questions regarding development of the dental pulp nerve system to be add...

Derived from neural crests, the mature pulp is due to the proliferation and condensation of apical cells implicated in root lengthening. Adult cells are bound together by intercellular junctions (desmosomes and gap junctions), forming a network. They are further transported to the crown. Root lengthening is associated to tooth eruption and to vertical sliding. Composed by type I and III collage...

Paper sheets from Iranian olive tree produced by soda, sulphite and kraft pulping.Then the influence of pulp beating on properties of paper sheets was studied. Kraft pulp exhibited the highest holocellulose/yield -cellulose/yield ratios and the sulphite pulp the soda pulp the highest lignin/yield ratio. Paper sheets from kraft with the breaking length 5851 m, stretch 4.61%, Burst index 4.48 KN/...

Dental preparation sometimes causes transient congestion, edema, and necrosis of the pulp. We hypothesized that nitric oxide (NO) is involved in the pathophysiological changes in pulp after preparation. The mRNA and protein expression of the inducible isoform of NO synthase (iNOS) was examined in murine pulp after dental preparation. The effects of NO on the proliferation, mineralization, and a...
