Abstract
This study was carried out to analyze the characteristics of the
smile in the Egyptian population using standardized photographic
records.
A sample of two hundred Egyptian subjects was equally
divided into one hundred males and one hundred females with age
range from 18-23 years. For each a frontal extra-oral photo at rest,
with posed smile, an oblique extra-oral photo with posed smile, and a
frontal intra-oral photo were taken.
Each frontal extra-oral photo with posed smile was used to
define the different smile characteristics (smile arc, smile line height,
relation of the dental midline to the facial midline, symmetry of the
smile, smile index, buccal corridor percentage). The oblique extraoral
photos
with
posed
smile
were
used
to help
identifying
the smile
arc
and
the
smile
height.
The
frontal
intra-oral
photographs
were
used
to
quantify
the tooth proportionality.
The data collected from the smile photographs were tabulated
and statistically analyzed.
