A technique for three-dimensional microleakage assessment using tooth sections

Microleakage of high viscosity glass-ionomer and glass-carbomer with and without coating before and after hydrothermal aging

“…Decreased use of dental amalgam and increased demand for aesthetic restorations resulted in implementation of direct toothcoloured restorations in clinical dentistry. The most commonly used minimal invasive tooth-scanning electron microscopic examination [29][30][31], air pressure, [32], dye penetration [33][34][35][36], the use of a chemical tracer [37,38], the use of radioactive isotope tracer [39][40][41], neutron activation analysis [42], electrochemical methodologies [43], measuring bacteria penetration [44], the artificial caries method [45] and three-dimensional image analysis [46]. The most employed method among all of these methods is still quantifying migration of dye penetration along the tooth/restoration interface [47,48].…”

Effect of nonvital bleaching with 10% carbamide peroxide on sealing ability of resin composite restorations

“…1998). A significant limitation in this study is the use of a longitudinal midline section to assess the depth of dye penetration, whereas the use of serial sections to give a more comprehensive picture has been described by Youngson (1992). The midline section, however, is widely used within the research field and may provide a ‘worst case analysis’ of dentine penetration as it allows visualization of what is usually the deepest aspect of a cavity and is therefore associated with the most permeable dentine (Youngson et al .…”

Three-dimensional evaluation of gap formation of cervical restorations

“…[24][25][26] In addition, Youngson reported that the extension of a dye along the cavity wall was evaluated three-dimensionally by overlapping many images of sample sections, and that the amount of the extension of the dye was presumed. 27 However, this tracer penetration method may not be always accurately show the extension of a gap; as noted above.…”
