Photobiomodulation (PBM) is a clinically accepted tool in regenerative medicine and dentistry to improve tissue healing and repair and to restore the functional disability. The current in vitro study aimed to investigate the photobiomodulatory effects of 980nm wavelength (the real energy at the target: ∼0.9 W, ∼0.9 W/cm2, 60 s, ∼55 J/cm2 and a single energy ∼55 J in CW) on MC3T3-E1 pre-osteoblast, delivered with flattop profile in comparison to the standard profile. The laser groupings and their associated energies were: Group 1 - once per week (total energy 110 J); Group 2 - three times per week (alternate day) (total energy 330 J); Group 3 - five times per week (total energy 550 J). The metabolic activity and the osteoblasts maturation were analyzed by alkaline phosphatase assay, alizarin red S histological staining, immunoblot and/or double immunolabeling analysis for Bcl2, Bax, Runx-2, Osx, Dlx5, osteocalcin, and collagen Type 1. Our data, for the first time, prove that laser irradiation of 980 nm wavelength with flat-top beam profile delivery system, compared to standard-Gaussian profile, has improved photobiomodulatory efficacy on pre-osteoblastic cells differentiation. Mechanistically, the irradiation enhances the pre-osteoblast differentiation through activation of Wnt signaling and activation of Smads 2/3-βcatenin pathway.

Conventional periodontal therapies have been widely discussed in the literature. The results of these therapies, surgically and non-surgically, have demonstrated high predictability and stable maintenance over time. With some clinical indications, such as inflamed sites with consistent bleeding on probing (BOP), it can be challenging for the root planning procedure to achieve predictable outcomes. Therefore, the aim and objectives of the present study were to evaluate whether the dual-wavelength (980 and 635nm) laser therapy at lower power settings can be beneficial as a combined non-invasive modality in the management of periodontally diseased root surface in terms of improving the periodontal parameters. Thirty-five healthy patients were enrolled in this study. All patients had at least one pocket in the anterior and posterior teeth with initial periodontal pocket depth (PPD)>6mm associated with evidence of clinical inflam- mation, i.e. bleeding on probing (BOPþþ or BOPþþþ) with no gingival recession. The treat- ment protocol utilized combined therapy of conventional debridement immediately followed by application of dual-wavelength laser therapy (photo-ablation and photodynamic therapies) at lower power settings. The results showed that all the pockets of involved teeth had an average gain of 3 mm of the clinical attachment level with no sign of BOP and reduction in the mobility of the teeth 35days post-operatively. Thus, the utilization of the dual-wavelength approach of laser-assisted therapy at lower power settings appears to provide a promising and predictable non-invasive clinical approach in the management of compromised periodontally involved teeth.

Background and aims: The long duration of orthodontic treatment is a major patients’ concern. A non- invasive method of accelerating tooth movement in a physiological manner is needed. The aim of the study was to evaluate the effects of Er:YAG laser application during orthodontic treatment of deep bite and to evaluate its analgesic effect during that movement. Materials and methods: A prospective randomized controlled clinical trial (RCT) was performed on 30 patients with deep bite. Sample was divided into two groups: (A), 15 patients (orthodontic treatment -control group) and (B), 15 patients (orthodontic treatment and Er:YAG Laser - laser group). The tooth movement was evaluated as the primary outcome variable by measuring angular and linear changes on three progress lateral cephalometeric radiographs (T1, T2 and T3); Lateral cephalograms were taken be- fore treatment (T1), immediately after finishing the stage of leveling and alignment (T2) and after com- pletion of the intrusion stage (T3). Laser parameters were 400 mJ/10 Hz/4 W and 400 mJ/15 Hz/6 W, depending on the handpiece used. The levels of pain and discomfort were evaluated and ranked according to a visual analog scale. Paired t-tests or Wilcoxon matched-pairs signed-rank tests were used to detect significant differences. Results: The main findings of the treatment were (1) significant positive difference in the rates of tooth intrusion movement on the experimental group compared with the control group at the baseline to T2 and T3 interval and the tooth movement rate was approximately 3 times faster in the experimental group. (2) The pain score in the experimental group was significantly lower compared with the control group on day 3 as on day 7. Conclusions: The application of Er:YAG laser is an effective mean to speed orthodontic tooth movement with a significant reduction in pain and discomfort after application.
