The efficacy of 2780 nm Er,Cr;YSGG and 940 nm Diode Laser in root canal disinfection: A randomized clinical trial

The efficacy of 2780 nm Er,Cr;YSGG and 940 nm Diode Laser in root canal disinfection: A randomized clinical trial

Effective disinfection of the root canals is the cornerstone of successful endodontic treatment. Diminishing the microbial load within the root canal system is crucial for healing in endodontically treated teeth. The aim of this study was to evaluate the effect of 2780 nm Er,Cr:YSGG and 940 nm diode lasers on the eradication of microorganisms from single-rooted teeth with asymptomatic apical periodontitis.

The Use of Lasers in Disinfection and Cleanliness of Root Canals: a Review

The Use of Lasers in Disinfection and Cleanliness of Root Canals: a Review

Effective root canal treatment depends on thorough disinfection and prevention of reinfection. Traditional chemomechanical methods often fall short, leading to endodontic failure. Laser treatment, due to its high energy and specific properties, has been proposed for root canal cleaning and disinfection. This review examines the effects of Er, Er,Cr, Nd, and diode lasers on smear layer removal and bacterial reduction. While lasers have bactericidal effects and can enhance smear layer removal and modify root canal wall morphology, they cannot replace sodium hypochlorite. Lasers should be used as an adjunct to chemical disinfection protocols. More randomized clinical studies are needed to evaluate the outcomes of laser-assisted endodontic treatment.

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.
