Clinical applications of antimicrobial photodynamic therapy in dentistry

Clinical applications of antimicrobial photodynamic therapy in dentistry

Antimicrobial photodynamic therapy (aPDT) is emerging as a promising non-invasive treatment for oral infections. It has been effective against bacteria, fungi, and viruses, including pathogens like Streptococcus mutans, Porphyromonas gingivalis, Candida albicans, and Enterococcus faecalis. Advances in natural, nano-based, and targeted photosensitizers have enhanced its efficacy. Clinical studies, crucial for evidence-based applications, have shown aPDT to be effective in reducing pathogenic bacterial loads in periodontal, peri-implant, and persistent endodontic infections. However, more randomized clinical trials are needed to determine optimal protocols and parameters. Further high-quality trials with specific photosensitizers and irradiation parameters are essential for establishing effective clinical practices.

Clinical Evaluation of Tissue Healing around Gingival Former Following DentalImplant Uncovery with two Different Diode Laser Wavelength

Clinical Evaluation of Tissue Healing around Gingival Former Following DentalImplant Uncovery with two Different Diode Laser Wavelength

This study evaluated tissue healing around gingival formers of dental implants after uncovery with different diode laser wavelengths. Conducted on 72 implants at Jundishapur University, Ahvaz, Iran, the study compared 940nm and 810nm diode lasers. Key indicators such as anesthesia needs, surgery duration, bleeding, pain, inflammation, edema, and gingival color were measured. Results showed no significant difference in surgery duration between the two groups. However, the 940nm laser required less anesthesia and resulted in lower pain intensity immediately and seven days post-surgery. Both groups experienced no bleeding. Overall, the 940nm diode laser performed better in the second stage of implant uncovering.

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.
