Prevalence of hypodontia in a sample of Sudanese orthodontic patients.
[]
The
aims
of
this
study
were
to
determine
the
prevalence
of
hypodontia
in
the
permanent
dentition
in
a
sample
of
Sudanese
patients
who
sought
orthodontic
treatment
and
to
compare
the
results
with
the
reported
findings
of
other
populations
.
Orthodontic
files
including
orthopantomographs
of
1069
patients
(
760
females
and
309
males
-
more
than
8
years
old
)
were
examined
and
inspected
for
evidence
of
hypodontia
.
The
prevalence
of
hypodontia
of
the
present
sample
was
5
.
1
%
.
Hypodontia
was
found
considerably
more
frequently
in
the
mandible
than
in
the
maxilla
.
The
distribution
of
missing
teeth
was
noticed
in
the
left
side
more
than
in
the
right
side
.
The
most
frequently
missing
teeth
were
the
maxillary
lateral
incisors
,
followed
by
the
mandibular
second
premolars
,
maxillary
second
premolars
and
mandibular
left
lateral
incisor
.
The
majority
of
patients
had
two
or
three
teeth
missing
,
but
rarely
more
than
5
teeth
missing
.
The
prevalence
of
hypodontia
of
this
study
was
within
the
range
of
that
reported
in
the
literature
.
The
incidence
of
hypodontia
in
the
anterior
segment
requires
great
need
for
orthodontic
and
prosthodontic
treatment
.
With
early
detection
of
hypodontia
,
alternative
treatment
modalities
can
be
planned
and
performed
with
a
multidisciplinary
team
approach
restoring
the
esthetic
and
function
.
