The Blue Wavelengths in Laser Dentistry

The Blue Wavelengths in Laser Dentistry

The article reviews current literature on the application of blue diode lasers (445–450 nm) in dental procedures. These lasers show strong absorption in pigmented tissues like hemoglobin and melanin but low absorption in water, providing high cutting efficiency and tissue selectivity. Clinical applications include soft tissue surgeries, bacterial decontamination, and aesthetic treatments such as whitening. However, due to their intense absorption characteristics, careful power control is necessary to prevent overheating and tissue damage. The review underscores the promising potential of blue lasers in dentistry and calls for more clinical studies to establish their safety and effectiveness.

Non-Ablative Gingival Depigmentation Diode Laser 450 nm

Non-Ablative Gingival Depigmentation Diode Laser 450 nm

This article presents a clinical case using a 450 nm diode laser to treat gingival melanin pigmentation. The laser’s high melanin absorption enables precise, non-ablative removal of dark pigmentation on the gums. The patient reported no pain, bleeding, or swelling, and healing was fast with excellent cosmetic results. After three months, no recurrence was observed, confirming both efficacy and safety. This treatment offers a minimally invasive alternative for improving smile aesthetics.

Assessment of Healing after Diode Laser Gingivectomy Prior to Prosthetic Procedures

Assessment of Healing after Diode Laser Gingivectomy Prior to Prosthetic Procedures

This pilot study examined gingival healing following diode laser gingivectomy in 41 teeth before prosthetic procedures. Key parameters assessed included recovery time, impression feasibility, procedure duration, bleeding, tissue adherence, postoperative hemorrhage, pain, and wound healing. At 24 hours, all gingival wounds had fibrinous plaque and an erythematous halo. By 72 hours, 4.9% of wounds advanced to a granulated surface with a normal pale pink color. At one week, 24.4% of cases had a granulated surface, while 75.6% showed complete healing. By the second week, all wounds had a normal pale pink color. Bleeding was minimal, and postoperative pain was low or nonexistent. No postoperative hemorrhage occurred after the first week. Tissue recovery in terms of contour, color, and wound appearance was asymptomatic. The study concluded that laser gingivectomy allowed clinicians to perform prosthetic procedures in the same visit.
