Association between temporomandibular disorder and body mass index in institutionalized children
Brazilian Journal of Oral Sciences(2010)
Abstract
Temporomandibular disorders (TMD) is a term applied to functional
changes of the temporomandibular joint (TMJ) and associated structures
of mastication. Aim: To investigate the correlation between body mass
index (BMI) and TMD in children. Methods: 70 children between 6 and 14
years enrolled in the Rogationist Benevolent Institute of charity in
the city of Sao Paulo (Brazil) underwent clinical examination by
one calibrated examiner for the use of Research Diagnostic Criteria for
TMD. Weight and height were determined by anthropometric assessment for
the diagnosis of nutritional status, and BMI was calculated by dividing
weight in kilograms by height in meters squared (kg/m2). Descriptive
analysis (mean and standard deviation) was used to characterize the
sample. ANOVA complemented by the Least Significant Difference test was
used to compare the mean anthropometric measurements between the
genders and the groups with and without TMD. The significance level was
set at 0.05. Results: We found a significantly high prevalence of TMD,
as well as a significant association between TMD light and low body
weight. Conclusions: The results show a high prevalence of TMD and a
slight association between TMD and children with low body weight.
