Millions of teeth are saved each year by root canal therapy. Although current treatment modalities offer high levels of success for many conditions, an ideal form of therapy might consist of regenerative approaches in which diseased or necrotic pulp tissues are removed and replaced with healthy pulp tissue to revitalize teeth. Researchers are working toward(More)
The regeneration of immature permanent teeth following trauma could be beneficial to reduce the risk of fracture and loss of millions of teeth each year. Regenerative endodontic procedures include revascularization, partial pulpotomy, and apexogenesis. Several case reports give these procedures a good prognosis as an alternative to apexification. Care is(More)
The projected annual demand for stem cell-based dental treatments in the United States can range from over 290 million tooth restorative treatments to 30,000 patients requiring tissue regeneration following craniofacial cancer surgery. Professional dental treatments cost Americans over $60 billion per year. Scientific advances in stem cell technologies,(More)
The purpose of this study was to measure cell survival and degradation within tissue-engineered dental constructs. Dental pulp stem cells (DPSCs) and periodontal ligament stem cells (PLSCs) were seeded on three types of tissue engineering scaffolds: a synthetic open-cell D,D-L,L-polylactic acid (polymer) scaffold, a bovine collagen scaffold (collagen), and(More)
INTRODUCTION This phase I, multicenter, open-label, single-arm, dose-escalation study evaluated the safety, pharmacokinetics and antitumor activity of APTO-253, an inducer of the transcription factor KLF4, in adults with advanced solid tumors. METHODS APTO-253 was administered IV on days 1 and 2, and 15 and 16 of each 28 day cycle; the dose were escalated(More)
OBJECTIVE The purpose of this study was to evaluate pulpal responses to the use of four resin composite materials as direct pulp capping agents. The importance and effects of individual pulp capping variables are not well understood; consequently histomorphometric analysis was used to analyze these variables. METHOD AND MATERIALS Two hundred fifty(More)
PURPOSE To investigate pulpal injury by measuring odontoblast numbers, and pulp dentin repair activity by measuring reactionary dentin area, in relation to the remaining dentin thickness (RDT) of cavity preparations in 217 human teeth. MATERIALS AND METHODS Cavities were restored with adhesive bonded composite, resin-modified glass-ionomer cement, zinc(More)
OBJECTIVES Dentinal repair following cavity restoration is dependent on several parameters including the numbers of surviving odontoblasts. The purpose of this study was to examine the effects of cavity cutting and restoration treatments on post-operative odontoblast numbers. METHODS 353 Standardised non-exposed rectangular Class V cavities, were cut into(More)
AIM To evaluate pulp responses as a function of remaining dentine thickness (RDT) of 98 class V cavity preparations in 49 teeth of 31 patients aged 10-16 years. METHODOLOGY Shallow cavities were restored with amalgam, deeper cavities or pulp exposures were restored with amalgam lined with calcium hydroxide or with zinc oxide eugenol. Teeth were extracted(More)
