Photobiomodulation With Infrared and Dual-Wavelength Laser Induces Similar Repair and Control of Inflammation After Third Molar Extraction: A Double-Blinded Split-Mouth Randomized Controlled Trial.

Biomechanical behavior of three maxillary expanders in cleft lip and palate: a finite element study.

This study evaluated the stress distribution in the dentoalveolar and palatal bone structures during maxillary expansion in a 17-year-old male patient with bilateral cleft lip and palate (BCLP) using expanders with dental (HYRAX) and skeletal anchorage (MARPE). For the generation of the specific finite element models, cone-beam computed tomography was used, and the DICOM files were exported to Mimics 3-Matic (Materialise) and Patran (MSC Software) software. Three specific three-dimensional models were generated: A) HYRAX: conventional four-banded hyrax screw (9 mm); B) MARPE-DS: 3 miniscrews (1.

Effect of the association of infra-red and red wavelength photobiomodulation therapy on the healing of post-extraction sockets of third lower molars: a split-mouth randomized clinical trial.

The aim of this study was to evaluate the effect of photobiomodulation therapy (PBMT) with the association of red and infra-red laser therapy in the healing of the post-extraction sockets of third lower molars. Twenty patients were submitted to extraction of lower third molars and the post-extraction sockets were treated using two different approaches in a randomized split-mouth design: The test side received the PBMT with red (λ 660 nm) and infra-red laser therapy (λ 808 nm) and the control side was not irradiated. The PBMT was applied immediately and 3 and 7 days after the surgical procedure.
