Purpose: To evaluate the clinical effects and surgical techniques of Neodymium-yttrium, aluminum, garnet(Nd: YAG) laser therapy for persistent pupillary membranes.
Methods: Twenty-five patients (26 eyes) with persistent pupillary membranes were suffered to resection membranes. The energy of laser was adjusted according to the thickness and density of the membranes. The laser with the best cutting effects and lowest energy was selected to resection. All patients were followed up for 3 - 6 months after the operation.
Results: All patients were cured after one laser therapy. The corrected visual acuities were improved in different degrees. Three eyes were 0.6 - 0.7 (11.5%), 5 eyes were 0.8-0.9 (19.2%) and 18 eyes were > or = 1. 0 (69.2%). No complication was observed.
Conclusion: The laser therapy for persistent pupillary membrane is an easy, safe and effective method only if the laser energy is appropriately selected, the focus is accurate and the operation is dexterity.

Efficacy and safety of laser interstitial thermal therapy versus radiofrequency ablation and stereotactic radiosurgery in the treatment of intractable mesial temporal lobe epilepsy: a systematic review and meta-analysis.

Epilepsy is a common neurological disease that is treated with medications; however, patients with drug-resistant epilepsy, commonly intractable temporal lobe epilepsy, tend to have better control with surgical treatment. While the mainstay of surgical treatment is anterior temporal lobectomy, it carries risk of potential adverse effects hence minimally invasive techniques are now being used as an alternative to open surgery. This systematic review and meta-analysis compare the efficacy and safety of three of the most used techniques: laser interstitial thermal therapy (LITT), radiofrequency ablation (RFA) and stereotactic radiosurgery (SRS).

The present study investigates the potential contribution of Photobiomodulation (PBM) to the regeneration of the bone following the extraction of the first mandibular molar in rats. The study evaluates the efficacy of PBM, using both Low-Level Laser Therapy (LLLT) and Light-Emitting Diode Therapy (LEDT), as promotors of osteoblastic activity and the formation of new bone. Study design, setting, and sample: 45 male Wistar rats were divided randomly into three groups of 15 individuals - (i) control group (left lower molar removed only), (ii) the LLL group (molar removed, followed by LLLT), and (iii) the LED group (molar removed, followed by LEDT).

Oral paresthesia occurs when one of the nerves in the region is injured, usually the inferior alveolar and/or lingual nerve, after dental procedures such as the extraction of lower third molars. The objective of this study was to describe the case of a patient who received photobiomodulation (PBM) therapy for paresthesia of the inferior alveolar nerve (IAN) caused by the extraction of mandibular third molars. The protocol used involved a super-pulsed diode laser with dual wavelengths of 810 nm and 980 nm, 1 W, 60 seconds, 12.

Green lasers have a stronger effect on promoting osteoblast differentiation, which is critical for orthodontic tooth retention. This study investigated the impact of green laser photobiomodulation on orthodontic tooth retention in rats. A total of 100 male Sprague-Dawley rats were divided into two groups: Group A (control) and Group B (green laser irradiation).

It is not uncommon for individuals receiving radiotherapy for head and cancers to experience dry mouth sensation (xerostomia), salivary hypofunction (hyposalivation) and taste changes. The present study aimed to evaluate the short-term effectiveness of biweekly photobiomodulation therapy (PBMT) in managing these radiotherapy-induced adverse effects and its impact on oral health-related quality of life. Ten patients who developed xerostomia and hyposalivation secondary to radiotherapy for head and neck cancer were included.
