Effect of 850 nm LED irradiation on the alignment of crowded mandibular anterior teeth: a randomized controlled clinical trial.

Introduction: This study aims to determine if intraoral 850 nm LED irradiation could reduce the duration of lower anterior crowding alignment.

Methods: In a parallel-designed, randomized controlled clinical trial 60 patients with 2 to 6 mm of lower incisor crowding who need non-extraction treatment, were randomly assigned to the intervention and control groups by block randomization (36 females, 24 males, mean age: 19.93 ± 3.

Evaluation of the relationship between maxillary canine impaction with arch dimensions and maxillary sinus dimensions using Cone Beam Computed Tomography (CBCT ).

Background: We aimed to evaluate the morphology of maxilla and sinus dimensions in subjects with unilaterally and bilaterally impacted canine using cone beam computed tomography (CBCT) records.

Methods: CBCT records taken during 2020-2022 of 120 patients were obtained to investigate the relationship between impacted canine and maxillary morphology as well as sinus dimensions. The CBCT images were then divided into three groups: control, unilaterally canine impaction and bilaterally canine impaction.
