Brief summary

The aim of this study was to evaluate the effectiveness of occlusal splint in pediatric bruxist patients by ultrasonic measurements of masseter muscle thickness and pain perception.

Detailed description

The aim of this study was to evaluate the effectiveness of occlusal splint by ultrasonographic measurements of masseter muscle thickness and pain perception in a group of pediatric bruxist patients. The study included patients aged 7 to 12 years, all in the mixed dentition period, with class I occlusion and diagnosed with probable bruxism. A 2 mm thick soft occlusal splint was prepared for each patient. Ultrasonic measurements were used to assess the thickness of the masseter muscle (MMT) at baseline, one, two and three months.Visual Analog Scale (VAS) was also used to record subjective pain measurements. Repeated-measures ANOVA and Friedman test were used in the statistical analysis

Inclusion criteria

* Symptoms of tooth clenching or grinding when sleeping at night or during the day, including headaches in the morning, as reported by parents during anamnesis. * Attrition-type tooth wear, as well as discomfort, fatigue, and/or pain in the jaw muscles when palpated during a clinical examination. The clinical diagnosis of attrition was based on the following findings: * Shiny and flat facets. * The enamel and dentin wear at the same pace. * Wear patterns on opposing teeth's occlusal surfaces. * Possible breakage of cusps or restorations. * Impressions on the cheeks, tongue, or lips.

Exclusion criteria

* Children with any chronic/systemic/psychological disease, presence of TMD symptoms, lack of posterior teeth that may cause unilateral chewing, use of any medication that may affect muscle activity, dental malocclusions (any skeletal jaw problems in anteroposterior and vertical dimensions) and ongoing orthodontic treatment

Design outcomes

Primary

MeasureTime frameDescription
muscle thickness measurementfrom the beginning to the third monthMasseter muscle thicknes was measured from a single position at the thickest part of the muscle, close to the occlusal plane and midway between the zygomatic arch and the gonial angle. Masseter muscle thicknes was evaluated bilaterally, in both the relaxed and contracted (maximum biting) positions.
