Effects of Superpulsed Low-level Laser Therapy on Temporomandibular Joint Pain

Effects of Superpulsed Low-level Laser Therapy on Temporomandibular Joint Pain

This randomized double-blind study evaluated the effectiveness of superpulsed low-level laser therapy (SLLLT) compared with ibuprofen and placebo in managing temporomandibular joint disorders (TMD) related to disc displacement without reduction or osteoarthritis. A total of 99 patients were divided into three groups: SLLLT (39 patients, 10 sessions), ibuprofen (30 patients, 800 mg twice daily for 10 days), and sham laser placebo (30 patients). Pain intensity (VAS) and mandibular function were assessed throughout treatment and follow-up. Results showed that SLLLT significantly reduced pain compared with both ibuprofen and placebo from day 5 onward (P=0.0001). Additionally, improvements in active and passive mouth opening and lateral motions were more evident in the SLLLT group after 1 month (P=0.0001). Overall, SLLLT demonstrated superior efficacy in pain relief and functional recovery, proving its effectiveness as a noninvasive therapy for TMD.

Effectiveness of Laser-Assisted Teeth Bleaching: A Systematic Review

Effectiveness of Laser-Assisted Teeth Bleaching: A Systematic Review

This systematic review evaluated 40 studies (in vitro and in vivo) to assess how lasers affect the whitening of natural teeth and dental restorative materials, compared to conventional bleaching. Diode lasers (808-980 nm) were used most often; about a quarter of these showed better whitening than standard methods. KTP, Er: YAG, and Er,Cr: YSGG lasers also demonstrated beneficial effects, though with more variability in efficacy and longer exposure in some cases. In contrast, argon and AsGaAl lasers were generally not more effective than conventional bleaching. Restorative materials, such as composites and ceramics, showed limited or no substantial whitening; composites in some studies even suffered adverse changes in surface properties and increased risk of future discoloration. The review concludes that laser-assisted bleaching can improve outcomes for natural teeth, but more research is needed, especially regarding safety and effects on restorative materials.

Examining the Efficacy of a 405 nm Wavelength Diode Laser as a Diagnostic Tool in Routine Dental Practice

Examining the Efficacy of a 405 nm Wavelength Diode Laser as a Diagnostic Tool in Routine Dental Practice

Recent advancements in dental diagnostics highlight laser fluorescence (LF) as a promising tool. This report explores the use of a 405 nm diode laser in treating biofilm-induced gingivitis and diagnosing restorations and caries in two patients (24-year-old male, 21-year-old female). In the first case, the laser improved visualization of plaque and calculus, aiding patient education and enabling precise mechanical debridement for better gingivitis treatment outcomes. In the second case, it detected defective composite fillings, supporting accurate diagnosis and patient communication for re-treatment. The 405 nm diode laser proves valuable for periodontal care and restorative dentistry.

Laser Technology in Dentistry: From Clinical Applications to Future Innovations

Laser Technology in Dentistry: From Clinical Applications to Future Innovations

This narrative review thoroughly examines how laser technology is used in modern dentistry, based on 67 studies from 2018 to 2023. It covers the latest advancements, such as photobiomodulation (PBM), which speeds up tissue healing and controls inflammation. The review also highlights new applications in dental implants, root canal treatments, and teeth whitening. Findings show that lasers greatly improve the accuracy of dental procedures and enhance patient results. However, challenges like high costs and the need for specialized training slow their widespread use. The review stresses the importance of incorporating lasers into everyday dental practice and points to opportunities for future innovations in the field.

1940 nm vs. 1470 nm EVLA: 3-Year Results with Radial Fiber

1940 nm vs. 1470 nm EVLA: 3-Year Results with Radial Fiber

This prospective, single-center study evaluated the safety and efficacy of 1940 nm endovenous laser ablation (EVLA) with a radial fiber over a 3-year follow-up. A total of 177 procedures were performed on incompetent great and small saphenous veins. The results showed significant reductions in vein diameter and complete disappearance of treated segments. Compared to historical data on 1470 nm EVLA, the 1940 nm laser demonstrated lower postoperative pain, fewer complications, and effective vein occlusion with less energy. Manual pullback and individualized dosimetry (40–60 J/cm) contributed to favorable outcomes. While the study was non-randomized and limited by COVID-19, findings support the use of 1940 nm EVLA as a safe, efficient option for treating truncal vein incompetence. Further randomized studies are recommended.
