Comparative effects of photobiomodulation therapy at wavelengths of 660 and 808 nm on regeneration of inferior alveolar nerve in rats following crush injury.

The aim of the present study was to investigate the therapeutic effects of 660-nm and 880-nm photobiomodulation therapy (PBMT) following inferior alveolar nerve (IAN) crush injury. Following the nerve crush injuries of IAN, 36 Wistar rats were randomly divided into three groups as follows: (1) control, (2) 660-nm PBMT, and (3) 808-nm PBMT (GaAlAs laser, 100 J/cm, 70 mW, 0.028-cm beam).

Evaluation of the Effects of Low-Level Laser Therapy on Diabetic Bone Healing.

The aim of the present study was to evaluate the effects of low-level laser therapy (LLLT) and biphasic alloplastic bone graft material on diabetic bone healing. Induction of diabetes was performed in 14 male Sprague-Dawley rats by intraperitoneal injection of a 50 mg/kg dose of streptozotocin. Two bilaterally symmetrical non-critical-sized bone defects were created in the parietal bones in each rat.

Two-stage treatment of TMJ ankylosis by early surgical approach and distraction osteogenesis.

Temporomandibular joint (TMJ) ankylosis is characterized by the formation of bone or fibrous adhesion of the anatomic joint components, which replaces the normal articulation and limitation of mouth opening. Early surgical intervention is considered as a treatment procedure to release the joint ankylosis and to maintain the function of the joint. Longstanding temporomandibular joint ankylosis which starts during the active growth period in early childhood resulting in facial asymmetry.

Surgically assisted rapid maxillary expansion compared with orthopedic rapid maxillary expansion.

The objective of this study is to evaluate and compare the dental and skeletal changes occurring during orthopedic rapid maxillary expansion (RME) and surgically assisted RME during the active phase of treatment. The study was divided into two groups. The first group of 10 patients (six males, four females; mean age, 15.
