restorations evaluated in this study, so the same Front
tooth erosion is justi able.
CONCLUSION
According to the results obtained in present experimen-
tal study, the means of erosion rate in two restorations
of layered IPS e.max heat press and Feldspathic Porce-
lain has no statistically signi cant difference with each
other, although mean of erosion rate in the Feldspathic
Porcelain has been somewhat lower than layered IPS
e.max heat the press; The results showed that the ero-
sion on both the restorations after intervention has been
signi cant compared to before intervention; As a result,
it can be concluded that these two restorations causes to
signi cant erosion of front tooth enamel, but have no
signi cant difference with each other.
SUGGESTIONS
It is suggested that in future research erosion caused be
evaluated by natural tooth enamel and other high appli-
cable restorations and also be compared by two restora-
tions of layered IPS e.max heat press and Feldspathic
Porcelain. It is also possible to design and carry out
long-term laboratory studies of this kind, to provide the
information necessary to assess the relationship between
laboratory and clinical erosion data.
