Assessing the association of taurodontism with numeric dentition anomalies in an adult central Indian population.
[]
To
study
the
association
between
taurodontism
and
numeric
anomalies
in
adult
population
.
Out
of
1
,
012
;
946
panoramic
radiographs
and
dental
records
were
retrospectively
assessed
to
determine
the
presence
of
dental
agenesis
and
supernumerary
and
taurodont
teeth
.
Taurodontism
of
one
or
more
teeth
was
observed
in
164
cases
(
97
females
and
67
males
)
.
Hypodontia
was
observed
in
148
patients
(
84
females
and
64
males
)
with
62
patients
having
associated
taurodontism
(
38
females
,
24
males
)
,
oligodontia
in
12
patients
(
five
females
and
seven
males
)
of
whom
nine
patients
also
had
taurodontism
of
one
or
more
teeth
(
five
females
and
four
males
)
.
Forty
-
five
patients
(
32
females
and
13
males
)
presented
with
57
supernumerary
teeth
(
ST
)
with
12
patients
having
simultaneous
presence
of
taurodontic
tooth
(
seven
females
and
five
males
)
.
Our
study
suggests
a
preferential
association
between
tooth
agenesis
and
taurodontism
;
however
,
such
association
was
not
observed
in
individuals
with
hyperdontia
.
Understanding
the
nature
of
this
preferential
association
may
be
of
importance
in
determining
the
etiology
of
both
conditions
.
This
association
may
also
define
a
subphenotype
for
future
genetic
studies
on
dental
development
.
Further
molecular
studies
are
necessary
to
verify
the
etiology
and
mechanism
of
taurodontism
associated
with
tooth
agenesis
.
