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.

Evaluation of tooth color change after a bleaching process with different lasers

Evaluation of tooth color change after a bleaching process with different lasers

This in vitro study evaluated the efficiency of diode laser-activated bleaching systems for teeth color change. Seventy-five extracted teeth were treated using five different bleaching protocols. Group 1 (diode laser 445 nm, 0.5W) showed the highest color change (∆Eab = 4.65). Groups 2, 3, and 4 also used diode lasers at different wavelengths and settings, while Group 5 was treated without laser activation. All laser groups demonstrated a significantly larger color change (∆Eab > 3) compared to the control group (∆E*ab = 0.73) (p < 0.05). The study concluded that laser-activated bleaching is more effective than conventional bleaching, with the 445 nm diode laser achieving the greatest color difference.

The temperature effects of diode laser on pulpal tissues forthe teeth whitening treatment

The temperature effects of diode laser on pulpal tissues forthe teeth whitening treatment

Teeth whitening using laser diode technology has gained popularity due to its advantages, such as shorter treatment times, and reduced tooth sensitivity and gingival irritation. However, a significant concern remains regarding the potential damage to pulpal tissues from the heat generated during treatment. This research focuses on both the change in teeth color and the temperature changes in pulpal tissues relative to the power density of the laser diode used. The study involved treating human-extracted teeth coated with 38% hydrogen peroxide using an 808 nm laser diode at power densities of 10.9, 16.1, and 36.7 W/cm². Two exposure methods were examined: a single exposure of 60 seconds and two exposures of 30 seconds each. Teeth color changes were measured using the CIE Lab* system. Results indicated that a higher power density (36.7 W/cm²) produced more luminous teeth but also significantly increased pulpal tissue temperature. A power density of 16.1 W/cm² was identified as the maximum safe limit to avoid damaging pulpal tissue. Additionally, the double-exposure method of 30 seconds each was more effective, yielding more luminous teeth with less heat generation compared to a single 60-second exposure.

Outcome of Diode Laser Assisted Endoscopic DCR

Outcome of Diode Laser Assisted Endoscopic DCR

This study evaluates diode laser-assisted endoscopic dacryocystorhinostomy (DCR) for treating chronic dacryocystitis in 49 patients from August 2015 to July 2016. Success and complications were monitored at intervals up to six months post operatively. The average patient age was 44.96 years, with a higher prevalence in females (71.4%). Complications included injury to the middle turbinate, sump syndrome, synechia, and granulation tissue formation. The overall success rate was 87.76%. The study concludes that laser-assisted endoscopic DCR is a cosmetically favorable, high-tech alternative to conventional external DCR with excellent outcomes.

Treatment of onychomycosis using a 1064-nm diode laser with or without topical antifungal therapy: a single-center, retrospective analysis in 56 patients

Treatment of onychomycosis using a 1064-nm diode laser with or without topical antifungal therapy: a single-center, retrospective analysis in 56 patients

Currently available treatment options for onychomycosis such as topical and systemic antifungals are often of limited efficacy, difficult to administer or associated with relevant side effects. Non-ablative laser therapy is proposed to represent a safe alternative without the disadvantages of drugs. Yet, to date, the efficacy of laser therapy for onychomycosis is discussed controversially. Against this background, we performed a systematic retrospective analysis of our clinical experience of 4 years of onychomycosis treatment applying a long-pulsed 1.064-nm diode laser.
