Finding an appropriate soft-tissue grafting material to close a wound located over the distal phalanx of the thumb, especially the pulp region, can be a difficult task. A sensate first dorsal metacarpal artery flap, mobilized from the dorsum of the adjacent index finger and used as an island pedicle skin flap, can be useful for this purpose. The pedicle includes the ulnar branch of the first do...

Active germinal centers are recognized as areas of rapidly proliferating blast cells in the white pulp of the spleen and in the cortex of lymph nodes. The origin and life history of these cells, their relationship to the surrounding mantle zone of small lymphocytes and, in particular, the functional significance of these two groups of cells is still unknown. Flemming (1) has proposed that germi...

Solid biofuels, such as bark, forest residues, sawdust, and wood chips are important mill fuels in the forest industry. They are combusted in combined heat and power plants (CHP-plants) to generate heat and electricity for pulp and paper making processes. Biofuels usually have high moisture content. The high moisture content decreases the effective heating value of fuel and makes the operation ...

introduction: hyperplastic pulpitis (pulp polyp)tissues contains cells with stem cell properties similar to that of the dental pulp stem cells (dpscs). it has also been shown that cd146 enrichment can homogenize the cultures of dpscs and enhance the colony forming potentials of their cultures. this study determines whether cd146 enrichment can help purifying the stem cells from heterogeneous cu...

Introduction: The main aim during any dental treatment is to maintain vital pulp as long as possible. Objective: The aim of this study was to assess clinically the use of MTA in direct pulp capping in adult patient. Method: MTA was performed in two visits treatment protocol on direct pulp capping in adult. Results: Clinical and radiological examination conducted after 7 months post treatment of...

Results Sixty six cases (71,2% female) met the inclusion criteria. Average age of RP onset was 12,5y with median duration of 3,6y. RP was associated to: erythema pernio (34,8%), inter-phalangeal joints pain (30.3%), hands edema (28,8%), acrocyanosis (18,2%), profuse sweating (12,1% ) and trophic changes of fingers pulp (10,6%.). Antinuclear antibodies (ANA) were titled in 64 patients (97%), bei...

Emphasis has shifted from the "doomed" organ concept of an exposed pulp to one of hope and recovery. The era of vital-pulp therapy has been greatly enhanced with the introduction of various pulp capping materials. The aim of this article is to summarize and discuss about the various and newer pulp capping materials used for protection of the dentin-pulp complex.

BACKGROUND Successful pulp regeneration depends on identification of pulp stem cells capable of differentiation under odontoblastic lineage and producing pulp-dentinal like structure. Recent studies demonstrate that platelet-derived growth factor (PDGF) plays an important role in damage repair and tissue regeneration. The aim of this study was to identify a subpopulation of dental pulp cells re...

Captive and wild African elephants frequently suffer tusk fractures. Several institutions shorten the tusks of captive elephants to reduce fractures and injury as a result of behaviour within enclosures. Fracturing or coronal amputations that expose pulp lead to pain for the elephant. Estimating coronal pulp lengths may thus help to minimise the risk of pulp exposure during amputations. We aime...
