The frequency of dental anomalies in subjects with cleft lip and palate
Objectives . The purpose of this study was to
investigate dental abnormalities in children
with cleft lip and palate (CLP) in order to identify
the most prevalent anomalies and the teeth
most frequently affected.
Materials and methods . We analyzed orthopanoramics
X-rays (OPT), computed tomography
Dental Scans, clinical records, and dental
casts from 18 consecutive patients (10 boys,
8 girls; mean age 11.2 years, range: 6 to 18),
with CLP (complete or incomplete, mono- or
bilateral) and recorded the presence of the
following anomalies: supernumerary teeth,
agenesis, shape and size anomalies, ectopic
and dystopic eruptions, rotations and retained
teeth.
Results . The most frequent abnormalities
were: agenesis (prevalence: 22.5%), ectopic and
dystopic eruption (19.3%), rotations (17.7%),
shape and size anomalies (16.1%), and retained
teeth (14.5%). The most frequently affected
teeth were the lateral (45.1%) and central
incisors (32.2%), the cuspids (14.5%), and the
second bicuspid (6.4%). Lateral incisors were
usually missing (39.2%) or retained (21.4%),
while central incisors were more often rotated
(50%) or deformed (25%). The cuspids were
ectopic (66.6%) or retained (23%), while the
bicuspids were missing (25%), retained (25%),
or presented alterations in number (25%) or
shape/size (25%)
