Effectiveness of adjunctive antimicrobial photodynamic therapy in reducing peri-implant inflammatory response in individuals vaping electronic cigarettes: A randomized controlled clinical trial
It is well-documented that cigarette smoking is an established risk factor for peri-implant diseases [1,2]. Habitual cigarette smoking has been associated with altered chemotactic and phagocytic functions of polymorphonuclear leukocytes and provokes a pro-inflammatory effect by stimulating the secretion of cytokines and reactive oxygen species that directly cause deterioration of peri-implant support [3]. Furthermore, toxins present in cigarette smoke undermine the peri-implant bone healing process [4]. (Source: Photodiagnosis and Photodynamic Therapy)

Photodynamic therapy of Curcuma longa extract stimulated with blue light against Aggregatibacter actinomycetemcomitans
Aggregatibacter actinomycetemcomitans is a pathogenic bacteria associated with aggressive periodontitis and also responds poorly to conventional treatment [1]. Photodynamic therapy (PDT) is an alternative treatment that has shown to effectively reduce periodontally pathogenic bacteria [2 –4]. Photodynamic reaction is based on light stimulation of an appropriate photosensitizer (PS) to generate reactive oxygen species that are toxic to the target cells and tissues [5–7].

Influence of ALA-mediated photodynamic therapy on secretion of interleukins 6, 8 and 10 by colon cancer cells in vitro
Photodynamic therapy with 5-aminolevulinic acid (ALA-PDT) can be an alternative to surgical resection in cases of pre-neoplastic lesions, early stages of colorectal cancer, colon polyps as well as a palliative treatment of advanced colorectal cancer. Clinical trials have shown the benefits of ALA-PDT in these fields of application [1 –5]. With regard to the immunomodulating effect of PDT, it was found that mainly sublethal PDT influences the expression of interleukins 6 and 10 in tumor and normal tissues and that these changes are involved in the observed effects of PDT on host immune responses [6–10].

The response surface methodology speeds up the search for optimal parameters in the photoinactivation of E. coli by photodynamic therapy
The Antimicrobial Photodynamic Therapy (a-PDT) is a non-invasive methodology that uses a non-toxic photosensitizer that can be activated by visible light of a specific wavelength, producing reactive oxygen species (ROS) by two different mechanisms [1] (Fig. 1). Peroxides and free radical species, produced by Type I mechanism, result from the interaction between the photosensitizer triplet excited state and the tissue, cells or microorganisms, inducing oxidative processes leading to cell death [2].

Effects of PACT using phenothiazine-derived drugs and red light on the macrophage x S. aureus interface
Macrophages and neutrophils are the main cells involved in phagocytosis [1]. Pathogen internalization can occur basically in two ways: active (phagocytosis) and passive. Passive pathogen internalization is characterized by cell invasion and phagocytosis is associated with the depletion of infectious processes [1,2]. During infectious inflammatory processes, the major molecules produced by the phagocytes of the immune system are free radicals, this event is known as “oxidative burst”. These molecules act unspecifically by de-structuring the pathogen or even by unbalancing metabolic pathways [1–3]. (Source: Photodiagno...

An in vivo evaluation of microbial diversity before and after the photo-activated disinfection in primary endodontic infections: Traditional phenotypic and molecular approaches
Primary endodontic infection is characterized by presence of wide range of microbial diversity dominated by anaerobes that initially invade the dental pulp [1]; this includes the large microbial diversity and count, which is constantly updated, and the microbial resistance to antimicrobial agents, used as intracanal medication in root canal treatment [2,3].

Efficacy of Er Cr: YSGG laser therapy at different frequency and power levels on bond integrity of composite to bleached enamel
Bleaching of the vital teeth has two major reasons. One is to remove extrinsic stains caused by coffee, tea or food color and the other is to minimize the intrinsic stains in the dentine [1]. However, unfortunately, these bleaching procedures have some unfavorable outcome on the enamel i.e. making enamel susceptible to carious attack, increase tooth sensitivity, loss of enamel prism core [2] and reduction in the bond strength of enamel to adhesive materials [3]. Adhesive bond failures compromise the outcome of the treatment, in the form of marginal staining, microleakage, recurrent caries and restorative failure [4]. (Sour...
