Purpose: The aim of the following study was to evaluate the use of low-level laser application on the width of the Mid palatal suture (MPS) after rapid maxillary expansion. Materials and methods: patients age range 10 ± 2.5 years were prospectively selected from outpatient clinic of the Orthodontic Department, Faculty of Dental Medicine for Girls, Al-Azhar University (Girls’ Branch). Each patient was examined, full diagnostic records and cone beam computed tomography (CBCT) were taken before appliance cementation (T0), after six months and at the end of retention phase (T1). The hyrax appliance was used for rapid maxillary expansion (RME). The activation protocol of the expansion screw was 2 full turns daily. The laser type used was the e Epic™ X diode laser system, 940 nm wavelength, 40 mW power, and 10 J/cm2 density. Results: No significant differences were found in the two areas between the control and the laser group. Conclusions: The mid palatal suture width showed no statistical significant differences between the control and laser group in anterior and posterior region.
