Effective Relief for Tooth Sensitivity with Dual-Wavelength Laser Therapy (660 nm & 810 nm)

Effective Relief for Tooth Sensitivity with Dual-Wavelength Laser Therapy (660 nm & 810 nm)

This study investigated the effects of 660 nm and 810 nm low-level diode lasers on patients suffering from dentin hypersensitivity. Participants received laser treatment without any surface anesthesia. Pain levels were evaluated before, immediately after, and one week post-treatment. Both wavelengths resulted in a significant reduction in sensitivity, with the 810 nm laser showing slightly better results in pain relief and longer-lasting effects. The findings suggest that low-level laser therapy is a reliable, safe, and efficient option for managing dentin hypersensitivity, improving patient comfort and satisfaction.

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

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.
