Purpose: The purpose of this study was to determine whether there is an association
between ankyloglossia and posterior crossbite in the pediatric population. A secondary
objective was to determine whether there is an association between ankyloglossia and
diagnosis of sleep-disordered breathing, behavior disorders, or speech disorders.
Methods: In this case-control study, clinical exam and chart reviews were completed on
patients 3-17 years old during scheduled dental visits to the Nationwide Children's
Hospital dental clinic. Participants were excluded if they had a history of craniofacial
anomalies, history of orthodontic treatment, history of frenotomy procedure,
uncooperative behavior, or did not speak English. Clinical examinations included
assessment of ankyloglossia using the Kotlow grading system, presence of posterior
crossbite, and Angle classification of malocclusion. All clinical examinations were
performed by a single examiner. Additionally, diagnoses of sleep-disordered breathing,
behavior disorders, and speech disorders were documented from each subject's electronic
medical record. Subjects with ankyloglossia were compared to age and sex matched
controls without ankyloglossia.
Results: There were 160 subjects, 80 subjects with ankyloglossia, and 80 control
subjects. In the ankyloglossia group, 39 subjects (48.75%) were Kotlow grade 1, 25
subjects (31.25%) Kotlow grade 2, 11 subjects (13.75%) Kotow grade 3, and 5 (6.25%)
Kotlow grade 4. The prevalence of posterior crossbite was 12.5% in the ankyloglossia
group and 16.2% in the control group. There was no statistically significant difference in
the prevalence of posterior crossbite between the ankyloglossia and control group (P=.5).
There was no statistically significant difference (P=1.00) in the prevalence of sleep disordered breathing, 3.8% and 5% in the ankyloglossia and control group, respectively.
There was no statistically significant difference (P=0.46) in the prevalence of (open full item for complete abstract)
