Bone Regeneration Using Dentin Matrix Depends on the Degree of Demineralization and Particle Size

PLoS ONE, 2016
Objectives This study aimed to examine the influence of particle size and extent of demineralization of dentin matrix on bone regeneration. Materials and Methods Extracted human teeth were pulverized and divided into 3 groups according to particle size ...

Dentin reactions to caries are misinterpreted by histological “gold standards” [v1; ref status: indexed, http://f1000r.es/2my]

F1000Research, 2014
Dentin reactions to caries, crucial for pathogenesis and for the determination of the severity of caries lesions, are believed to be reasonably detected by stereomicroscopy (SM) and polarized light microscopy in quinoline (PLMQ), but accuracies are not ...

The Effects of Platelet‐Derived Growth Factor‐BB on Human Dental Pulp Stem Cells Mediated Dentin‐Pulp Complex Regeneration

Stem Cells Translational Medicine, 2017
Dentin‐pulp complex regeneration is a promising alternative treatment for the irreversible pulpitis caused by tooth trauma or dental caries. This process mainly relies on the recruitment of endogenous or the transplanted dental pulp stem cells (DPSCs) to

Sodium Hypochlorite Irrigation and Its Effect on Bond Strength to Dentin

BioMed Research International, 2017
Effective shaping and cleaning of root canals are essential for the success of endodontic treatment. Due to the complex anatomy of root canal spaces, the use of various instrumentation techniques alone is not effective in producing bacteria-free root ...

Predicting protein decomposition: the case of aspartic-acid racemization kinetics [PDF]

, 1999
The increase in proportion of the non-biological (D-) isomer of aspartic acid (Asp) relative to the L- isomer has been widely used in archaeology and geochemistry as a tool for dating. The method has proved controversial, particularly when used for bones.

Body temperatures of modern and extinct vertebrates from ^(13)C-^(18)O bond abundances in bioapatite [PDF]

, 2010
The stable isotope compositions of biologically precipitated apatite in bone, teeth, and scales are widely used to obtain information on the diet, behavior, and physiology of extinct organisms and to reconstruct past climate.

DSP and DPP are dispensable for initiation of dentin and enamel mineralization but critical for circumpulpal dentin mineralization

Scientific Reports
Dentin sialophosprotein (DSPP) is cleaved into the N-terminal dentin sialoprotein (DSP) proteoglycan and the C-terminal dentin phosphoprotein (DPP; the most acidic proteins in humans).
