Afkhami et al1 published a study to evaluate the effects of PBMT on the pain caused by dental anesthetic injections. They concluded that photobiomodulation therapy prior to dental anesthetic injections has no clinical advantage for reducing injection pain.
Rapp and coworkers2 published a paper on the use of the femtosecond laser in cavity preparation which the readers may find interesting. The abstract is reproduced in full.
High fluence focused femtosecond laser pulses were used to perform fast, high precision and minimally damaging cavity cutting of teeth at room temperature without using any irrigation or cooling system. The optimal ablation rates were established for both enamel and dentin, and the surfaces were assessed with optical and scanning electron microscopy, Raman spectroscopy and optical profilometry. No chemical change in the composition of enamel and dentin was observed. We explored temperature variations inside the dental pulp during the laser procedure and showed the maximum increase was 5.5°C, within the acceptable limit of temperature increase during conventional dental treatments.
Lepri et al3 published a study showing that Er:YAG laser irradiation can safely increase the acid resistance of the dentin surface of the root, since it promoted a significant increase in surface hardness. The application of 2% NaF did not result in a synergistic effect.
Rathod and coworkers4 published a review of the use of Low-Level laser therapy in dentistry which readers may find of interest.
Alqutub, and coworkers5 published a study comparing the analgesic effects of LLLT and Ibuprofen after surgical dental extraction. They concluded that the pain level was lower in the control group, although the difference was not statistically significant.
Sekerci et al6 published a review of LLLT in dentistry. The abstract is reproduced in full.
Low-level lasers (LLL) are used in the stomatology and oral surgery field of dentistry. Due to the biostimulation or biomodulation and photodynamic effect, the healing process of soft-tissue and bone wounds can be accelerated. The indication in oral surgery is to achieve a faster bone healing after tooth extraction, but also to improve the osseointegration in implants. The advantage in stomatology is pain alleviation and improved healing in aphthae and cold sores as well as symptom relief in mucositis. Due to the use free of side effects and low time effort, the LLL offers high patient’s comfort.
Aldegheishem and coworkers7 published a study which aimed to evaluate the mechanical (i.e., flexural modulus [FM], flexural strength [FS], and surface roughness [Ra]) and antibacterial efficacy of photo-sonodynamic therapy via methylene blue-loaded poly(D,L-lactide-co-glycolide) nanoparticles (MB-loaded PLGA NPs) over dental implants for potential treatment of peri-implantitis. They concluded that the application of photo-sonodynamic therapy via MB-loaded PLGA NPs d demonstrated the greatest antibacterial activity against P. gingivalis without deteriorating the surfaces and compromising the mechanical properties of dental implants.
Mocuta et al8 published an article on the use Laser Er:YAG-Assisted debonding as a viable alternative to the conventional method for monocrystalline ceramic brackets. They concluded that it may be a viable alternative to the conventional method for monocrystalline ceramic brackets.
Kyaw and cowrkers9 published a systematic review of in vitro implant healing abutment decontamination studies and found that combined decontamination protocols (chemical, electrochemical processing and autoclave treatment) are favourable for obtaining healing abutments with optimally cleaned surfaces. Moreover, healing abutments located in an area that is difficult to access can be cleaned without affecting the surface properties.
