This study investigates the feasibility of a different new approach to
determining the microleakage volume associated with dental restorations
(Class V cavity restorated with glass ionomer cement + high copper
amalgam) and the relative marginal adaptation deficiency of dog, bovine
and human permanent teeth in in vitro conditions. Also researched is
the appropriateness of using dog and bovine teeth in in vitro studies
rather than human teeth. Our method utilizes the molecular adsorption
characteristics of methylene blue. Within the framework of this study,
60 permanent teeth (20 human, 20 dogs and 20 bovine) were used. These
groups were evaluated statistically, of which indicated no
statistically significant differences (p > 0.05). It was also
concluded that this preliminary investigation showed that the new
microleakage volume measurement method may be a valuable new technique
for the in vitro study of microleakage dynamics around dental
restorations
