Understanding the etiology and pathogenesis of periodontal diseases and their chronic, inflammatory and infectious nature necessitates recognizing the possibility that these infections may have effects somewhere in the body. The concept that oral diseases and systemic diseases influence each other goes back to the theory of “focal infection”. In 1891, Miller published his theory regarding focal infection in which he indicated that microorganisms and their products are able to access parts of the body that are adjacent to or distant from the mouth. The proponents of this concept assume that microorganisms present in dental plaque and their metabolic products may enter the bloodstream, thereby causing many systemic diseases and sometimes resulting in degenerative conditions. Associations have been reported between periodontal disease and cardiovascular disease (CVD), stroke, diabetes, preterm low birth-weight babies, respiratory infections and rheumatoid arthritis (RA).

Cleaning and shaping of the root canal space is the primary objective of endodontic therapy. Its purpose is to prepare the canal space in order to improve disinfection with the use of irrigants as part of chemo mechanical preparation. Infiltration and subsequent infection of the root canal system by microorganisms and their byproducts is the primary etiology of endodontic pathosis. Chemo-mechanical preparation aims to remove microorganisms, remaining pulp tissue and dentin debris from the root canal system.
The main objective of shaping is to maintain or develop a continuously tapering funnel from the canal orifice to the apex; however the complex canal anatomy causes instrumentation challenges, which may prevent adequate disinfection of the root canal system, or cause procedural errors such as instrument separation, transportation, ledges or perforations. The present study was set out to determine canal centering ability, transportation and curvature using 5th generation NiTi rotary systems as mentioned above.

Application of nanoparticles in different industries attracts special attention nowadays. Use of microorganisms is one of the actively studied directions for nanoparticles production. The strain of Pseudomonas stutzeri possessing capacity to bioformation of copper nanoparticles was selected as a result of conducted screening among collection cultures. Earlier this strain revealed activity in terms of biosynthesis of silver nanoparticles too. The possibility to regulate size and form of produced nanoparticles by regulating concentration of ions in the solution was established. The strain is considered as a potential source for development of the technology for production of copper nanoparticles.

Capability of different microorganisms to produce nanoparticles of silver (NPAg)
at different pH levels was studied. It was established that pH of the reaction medium
considerably affects form and size of produced nanoparticles. The fact of NPAg formation
produced by the different microorganisms was studied by UV-spectroscopy and AFmicroscopy
methods.It was determined that in the selected conditions of the synthesis both
clusters and nanoparticles of silver are produced ranging in size from 20 to 300 nm and
form absorption bands at max275 nm and 420 nm, respectively. It was revealed that
changeof pH level of the reaction system may result in regulation of the size and form of
the nanoparticles.
