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...

AIM To review the literature on pulp chamber and root canal obliteration in anterior teeth and to establish a clear protocol for managing teeth with fine, tortuous canal systems. SUMMARY Pulp canal obliteration (PCO) occurs commonly following traumatic injuries to teeth. Approximately 4-24% of traumatized teeth develop varying degrees of pulpal obliteration that is characterized by the appare...

BACKGROUND Pulp stones (PS) are discrete calcified masses found in the dental pulp, in the pulp tissue or become attached to or embedded into the dentine. The formation of pulp stones is still something of an enigma, leading to existence of some epidemiological gaps. AIM To determine the prevalence and distribution of pulp stones in posterior tooth group by using panoramic radiograph. MATER...

• If the pulp chamber of a tooth is penetrated, either by dental caries, or by a dental drill, inflammation and eventual death of the pulp tissue usually follows. While a long interval may elapse before degeneration is complete, necrosis is an almost inevitable consequence of pulpal penetration. A current explanation in the dental literature for this phenomenon is as follows. The application of...
