Objective
To compare the masseter muscle thickness (MMT) of patients with probable sleep/awake
bruxism and controls without bruxism in mixed dentition as measured with ultrasonography
(USG), and to calculate the correlation of MMT with body mass index (BMI).
Study Design
The diagnosis of probable bruxism was established based on the parents’ reports of
the children's behavior, habits, and discomfort, and the presence of clinical signs
and symptoms such as attrition-type wear on the teeth and the presence of discomfort,
fatigue, and/or pain in the jaw muscles on palpation during clinical examination.
The bruxist study group and the control group each included 28 children. MMT was measured
separately in relaxed and contracted positions in both groups using USG. The height
and weight of the patients were recorded in order to calculate BMI. Statistical analysis
was performed with significance established at P < .05.
Results
MMT was found to be significantly larger in the study patients than in controls on
the right and left sides in the relaxed and contracted positions (P < .001). No statistically significant correlation was found between MMT and BMI (P ≥ .134).
Conclusions
MMT as measured with USG can be a beneficial approach in diagnosing bruxism in children.
The lack of correlation between MMT and BMI indicates that BMI would not be helpful
in diagnosing bruxism.
