A controlled clinical trial was designed. The study popu-
lation consisted of first year dental and medical students
of the
İ
stanbul Medipol University who had no experi-
ence with either conventional or digital impressions. The
subjects were informed in detail about the possible risks
and benefits, and all signed an informed consent form.
The study was performed following the principles out-
lined in the Declaration of Helsinki on experimentation
involving human subjects. The study protocol was
reviewed and approved by the Ethical Committee of
the Istanbul Medipol University, Istanbul, Turkey
