Preventive effect of CPP–ACP paste on enamel erosion in vitro
Objectives . The present study aimed to evaluate preventive effect of Casein Phosphopeptide–Amorphous Calcium Phosphate (CPP–ACP) paste and artificial saliva on hardness of intact enamel eroded by a Cola drink….
Effect of artificial aging on bonding strength of fissure sealants
Objectives . The objective of the present study was to evaluate the effect of aging on the adhesion of total-etched and self-etched fissure sealants to ground enamel of bovine teeth…
Composite contraction stress remote from and at the bonded interface
Objectives . Polymerization contraction of bonded dental composite produces stress in the surrounding substrate. A simple method to calculate the local contraction stress using indentation crack extension was reported earlier…
Influence of filler concentration on the colorimetric parameters of colored resin matrices for dental composites
Objectives . The aim of the study was to assess the correlation between the percentage of fillers and the colorimetric parameters of colored resin matrices used for dental composites. Materials…
New factors predicting the shrinkage stress for bonded restorations interfaces
Objectives . The C-Factor is normally used to predict the shrinkage stress at composite-tooth interfaces. A study was outlined for clarifying the elements which allows providing the stress at bonded…
Fracture and fractography of experimental composites with different filler sizes
Objectives . To study the fracture mechanism of experimental resin composites with different filler sizes by determining their initial fracture strength (IFS), flexural fatigue limit (FFL) and by observing respective…
Controllable polymerizations: Interactions of monomer and iniferter structure
Objectives . Photo-iniferters are molecules capable of initiation, chain transfer and termination reactions, suitable to produce controlled radical photo-polymerizations, which can be useful, for example, when thermal stability is desired….
Gloss retention of nanocomposite resins after toothbrushing
Objectives . The purpose of this study was to evaluate the change of gloss for nanocomposite resins by toothbrushing. Materials and methods . Nine different composite resins were filled into…
Elastic moduli of direct restoratives: Influence of the testing method
Objective . The elastic modulus (EM) is the main constant characterizing the stiffness of a solid material. Different methods are known to describe this parameter, as there are mechanical (static…
