Abstract:

Background and Aim: Lasers can serve as a new powerful tool in dentistry. High intensity laser therapy is becoming the treatment of choice compared with conventional periodontal therapy due to accurate incision and soft and hard tissue ablation, hemostasis, reduction of postoperative pain and infection, optimal debridement, and enhanced healing. Although high intensity laser therapy assumes to provide better results compared with conventional treatments, a significant variation exists in the applied laser parameters such as different wavelengths and energy densities of laser. The objective of this study was to collect preliminary information about the type and parameters of surgical lasers and how to use them technically based on the available literature on this topic. Materials and Methods: After initial screening of 152 potentially relevant articles identified through an electronic search, 44 articles were selected based on the eligibility criteria by three independent reviewers. The inclusion criteria included studies on the outcomes of periodontal high intensity laser therapy in humans published in English between 2013 and 2021 in journals indexed in PubMed Central, Science Direct, Wiley Online Library, Springer or Google Scholar. Results: The results showed that diode, Nd:YAG, Er:YAG, Er;Cr:YAG and CO2 lasers had the highest efficacy for frenectomy, gingivectomy,  and osteotomy with specific wavelength, power density, frequency, and pulse mode. Various lasers have been suggested for the abovementioned purposes, and the method of choice depends on the efficacy and availability of laser. Conclusion: This study confirmed higher efficacy of different laser types compared with conventional treatments.

High-intensity Lasers in Nuclear Science

Recent developments in high intensity lasers open up a new approach to investigating nuclear reactions in the laboratory without access to nuclear reactors or particle accelerators. By focusing the laser spot, very high laser intensities in excess of 10 W cm can now be produced. Under these conditions, matter in the focal spot is turned into hot dense relativistic plasma. The laser interactions...

Immunization in Periodontics: A Systematic Review

Results: In vitro studies revealed a definitive inhibitory effect of vaccines over periodontal disease causing organisms and their vulnerability toward such agents. Among the studies reviewed, in vitro outnumbered the in vivo studies and there is definitely a lack in quality and quantity of human trials in this regard. Most in vitro studies have shown results in favor of vaccines preventing the...
