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.

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.

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 facial aging process is the result of anatomical changes in the facial bones and muscles that are ultimately expressed in the elasticity of the skin. Different strategies have been proposed for the management of photoaging such as radiofrequency, fillers, ablative laser with erbium:YAG laser (Er:YAG) and carbon dioxide laser; these last methods have demonstrated benefits in the effectiveness for skin rejuvenation. The minimally invasive facial endolifting technique reported with photothermal, photochemical advantages and long-term results.

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.

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.
