Effect(s) of the Demineralization Process on the Osteoinductivity of Demineralized Bone Matrix

Journal of Periodontology, 1997
The relationships between residual calcium levels and particle size of ground demineralized bone matrix and its osteoinductive potential were investigated using in vitro and in vivo assays. The effects of variable residual calcium levels, variable particle sizes, and donor age and gender were studied using a tissue culture‐based bioassay (in vitro) as ...

Demineralization of human enamel

European Journal of Oral Sciences, 1974
abstract— The aim of the present paper is to demonstrate that enamel can be dissolved in two, chemically distinct ways. Each of six premolars were exposed to 8 ml of a pH 5.0 buffer. The ionic activity products for Ca5(PO4)3OH, Ca5(PO4)3F, CaHPO4, CaF2andCa4H(PO4)3 were determined.

Demineralization and Remineralization

2016
Dental caries is caused by an imbalance between protective and pathologic factors such that the process of demineralization of tooth structure exceeds the ability to remineralized tooth structure. Different kinds of models have been widely used to study de-/remineralization process of dental hard tissue, including pH-cycling models, in vitro biofilm ...

Demineralization of Dentine Grooves in vitro

Caries Research, 2009
Caries mainly occurs at retention sites for plaque such as pits, fissures, margins of restorations and interproximal sites. An in vitro model was developed to investigate dentine caries in narrow gaps. Forty bovine coronal dentine discs were covered with bonding agent.

Demineralization by electrodialysis

Desalination, 1976
Abstract Electrodialysis process using ion-exchange resins in the compartments has been an approach in demineralization of low saline solutions but the difficulty of maintaining and operating such systems is a major bottleneck. The current work has made use of the concept of conducting spacers of anion and cation-exchange type made from polyblends or

Neovascularization of Surface Demineralized Dentin

Journal of Periodontology, 1989
Uneventful healing of the wound site created by periodontal reconstructive surgery is crucial for the long term survival of the dentition. Wound healing has been shown to be initiated and mediated by matrix components and polypeptide growth factors. Neovascularization (or angiogenesis) is one of the most important events in the healing process of a ...

Enamel Demineralization by Snack Foods

Journal of Dental Research, 1975
The amount of enamel destroyed by salivary fermentation of snack foods and confections was not dependent on their sugar content; starch, flavoring agents, and other components also played a part. Most enamel destruction was produced by fruit-flavored candies in which the inherent acid or high sugar concentration or both inhibited bacterial fermentation.

Demineralization of Bone by Phosphoprotein Phosphatase

Journal of Dental Research, 1970
Because of recent observations of the demineralization of enamel by phosphoprotein phosphatase, an experiment was designed to test this enzyme on bone. Decided destruction was evident in bone fragments that were incubated with phosphoprotein phosphatase buffered to pH 5.8 with 0.1 M acetate for periods of up to 15 hours.

Demineralization with EDTA by constant replacement

The Anatomical Record, 1965
AbstractAn apparatus for demineralization of hard tissues by constant replacement of a saturated solution of EDTA is described. This method allows for more rapid demineralization through better Ca chelation. EDTA demineralization preserves cells and matrix constituents particularly the mucopolysaccharides as demonstrated by staining, Alpharadiography ...
