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.

Can Antimicrobial Photodynamic Therapy (aPDT)Enhance the Endodontic Treatment?

Can Antimicrobial Photodynamic Therapy (aPDT)Enhance the Endodontic Treatment?

The study aimed to evaluate scientific literature on using different photosensitizers (PSs) for bacterial reduction in root canal treatment, particularly against Enterococcus faecalis. Databases such as PubMed, Scopus, and Google Scholar were searched with relevant keywords from 2000 to 2015. It was concluded that antimicrobial photodynamic therapy (aPDT) should be used alongside conventional mechanical debridement and irrigants for effective bacterial elimination. However, the success rate of aPDT depends on factors like the type of PS, laser output power, irradiation time, pre-irradiation time, and type of tips used.

Effectiveness of the Laser Application in Temporomandibular Joint Disorder: A Systematic Review of 1172 Patients

Effectiveness of the Laser Application in Temporomandibular Joint Disorder: A Systematic Review of 1172 Patients

This systematic review assessed the effectiveness of laser therapy in treating temporomandibular joint disorder (TMD). Databases including PubMed, SCOPUS, Science Direct, Web of Science, and Google Scholar were searched for studies in English from January 2001 to March 2020. A total of 32 studies involving 1172 patients were reviewed. Most studies reported significant pain reduction with laser therapy, with 78.13% showing better outcomes compared to conventional treatments. According to Robvis analysis, 84.4% of the studies had high methodological quality with low risk of bias. The review concluded that laser therapy is promising for reducing pain in TMD patients and can be recommended for better outcomes.

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.
