The effect of intra-oral LED device and low-level laser therapy on orthodontic tooth movement in young adults: A randomized controlled trial.

Introduction: This randomized controlled clinical trial aimed to assess the effect of LED and LLLT in a three-arm parallel setting.

Methods: Sixty patients who needed the maxillary first premolar extraction were allocated to three groups using the stratified block randomization method. In the LED group, a custom-made device with a wavelength of 640nm and a power density of 40 mW/cm was used 5min/day.

Mandibular asymmetry in young adult patients with unilateral posterior crossbite: A controlled retrospective CBCT study.

Objective: This study aimed to evaluate the mandibular skeletal asymmetry in pre-orthodontic patients with the unilateral posterior dental crossbite (UPCB).

Materials And Methods: Using a retrospective design, 30 pre-orthodontic patients with a UPCB, (16 on the right side, 14 on the left side), 18 females and 12 males were selected (mean age: 21.2±4.
