Biochemical composition of carious dentin and different layers of sound dentin.
The aim of this study was to evaluate the concentrations of calcium (Ca), inorganic phosphate (Pi) and fluoride (F) in carious dentin and in different layers of sound dentin. The samples examined were 52 permanent teeth (26 sound and 26 carious), which were subjected to two experiments to assess the mineral content of: 1) two layers (internal and external) of sound dentin and 2) sound and cario...
متن کاملDentin Matrix Protein 1 and Dentin Sialophosphoprotein in Human Sound and Carious Teeth: An Immunohistochemical and Colorimetric Assay
Dentin matrix protein 1 (DMP1) and dentin sialophosphoprotein (DSPP) are extracellular matrix proteins produced by odontoblasts involved in the dentin mineralization. The aim this study was to compare the distribution of DMP1 and DSPP in human sound dentin vs human sclerotic dentin. Sixteen sound and sixteen carious human molars were selected, fixed in paraformaldehyde and processed for immunoh...
متن کاملEvaluation of the Shear Bond Strength of Nanocomposite on Carious and Sound Deciduous Dentin
AIM The aim of the study was to evaluate and compare the shear bond strength of conventional composites with nanocomposites in carious and sound deciduous dentin with the use of self-etching adhesive. METHODOLOGY Human primary molars were ground to obtain flat dentin surfaces and divided into two groups: Carious dentin and sound dentin group. The carious teeth specimens were prepared by remov...
متن کاملEffectiveness and efficiency of chemomechanical carious dentin removal.
The aims of this in vitro study were both to determine the time necessary for removal of carious dentin (efficiency) and the Knoop Hardness Number (KHN) of the remaining dentin (effectiveness), using a chemomechanical method (Carisolv) or hand excavation. Thirty human molars were bisected through occlusal carious lesions into two equal halves. Each half was randomly excavated by hand in circula...
متن کاملRole of oral streptococci in the pH-dependent carious dentin
the extent to which oral streptococci or lactic acid producing bacteria are able to regulate pH value, especially at low pH values associated with dentinal carious activity using a PCR method. One millimeter-thick sections were sliced from 24 extracted carious human molars. The pH values on the tooth sections were evaluated using a pH-imaging microscope. A dentin sample (1×1×1mm) was prepared f...
