An interventional study of Surface EMG device in Malocclusion, sponsored by Riyadh Colleges of Dentistry and Pharmacy. Status unknown at 1 site in Saudi Arabia. Open to participants aged 9 Years to 15 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2017-10-09.
Sponsored by Riyadh Colleges of Dentistry and Pharmacy · Not applicable, Interventional, and Diagnostic
Compare the impact of using rapid maxillary expanders on masticatory muscle activities (Masseter and Anterior Temporalis muscles) among different posterior cross-bite patient (unilateral, bilateral) as well as compare the cross-bite side and non-cross-bite sides of the same preadolescent unilateral crossbite patient before the expansion and after one month of the completion treatment period using surface electromyography device.
Compare the impact of using rapid maxillary expanders on masticatory muscle activities (Masseter and Anterior Temporalis muscles) between the cross-bite side and non-cross-bite sides of the same preadolescent orthodontic patient before the expansion and after one month of the completion treatment period.
Two channels surface Electromyography sEMG (BioRadio), will be position to record the activity of anterior temporal (AT) and masseter (MM) muscles in three different statuses:
Clench → patients will instruct to made a maximum voluntary clench on cotton rolls positioned around the first molar, for 5 sec "the cotton clench", and a maximum voluntary clench without the interposed rolls for 5 sec "the "clench".
* This procedure followed the Sforza et al. protocol.
Examination frequency:
The patients will be examined two times as follow:
Test 1: Immediately before rapid maxillary expanders cementation, Test 2: 5 months later (1 month after the retention phase).
the same procedure will be done on 35 patients (control group)
469 studies on the registry are indexed under Malocclusion; 91 are open to participants now.
This study's planned enrollment of 50 is above the median of 36 across 383 interventional studies indexed under Malocclusion.

Exclusion Criteria:
6. Patients with symptoms of Temporomandibular disorders. 4. Neuropathic conditions. 5. Open and deep-bite.
unilateral crossbite patients with constricted maxilla, going to be treated by rapid maxillary expanders the surface Electromyography (surface EMG device) device will be used to examine the muscle activities before and after expansion
Device: Surface EMG device
the surface Electromyography (surface EMG device) device will be used to examine the muscle activities on normal patients
Bilateral crossbite patients with constricted maxilla, going to be treated by rapid maxillary expanders the surface Electromyography (surface EMG device) device will be used to examine the muscle activities before and after expansion
Device: Surface EMG device
measuring the muscles activity using surface EMG device
Also known as: BioRadio EMG Device
measuring the masticatory muscles activity using electromyography device
the muscle activities of masticatory muscles using surface Electromyography device before and compare it after the maxillary expansion using Rapid Maxillary Expanders (to study the impact of the expanders on the muscles), the muscle activity will be in form of micro volt/second (mV/sec), the data will aggregated then exported on excel sheet in a form of numbers for statistical analysis
Time frame: Test 1: before cementation of rapid maxillary expander, Test 2: after removal of rapid maxillary expander by 1 month
Plan to share: No — data will be used for a research purpose only , will not be shared with any other institution
