Abstract

The project will explore the generation of Plasma Activated Liquid (PAL) for applications related to dentistry. Due to the considerable promise of technology, there is an urgent need to develop a pilot scale PAL system that can be used to generate results with real relevance, especially in the dental field. This postdoctoral project will focus on: (i) developing and characterizing a PAL generation system and (ii) applying plasma-activated liquids in endodontic treatment. For this, techniques of mass spectrometry and optical emission spectroscopy will be used to study the physical and chemical properties of the generated plasmas, as well as their interaction with PAL. For microbiological tests, argon / air plasmas in physiological solution will be applied and subsequently these liquids will be evaluated for antimicrobial activity in dual-species biofilms of Candida albicans (SC 5314) and Enterococcus faecalis (ATCC 29212). Once the best conditions for inactivating the biofilms are verified, experiments will be carried out where the dual-species biofilms will be grown in the root canal of 50 fragments of uniradicular bovine teeth and treated with plasma activated liquid (PAL). Through microbiological analysis and the liquid treated with plasma, the PAL's actions on microorganisms will be discussed, as well as a protocol for the use of PAL in the dental environment will be established. Finally, a PAL generation system will be designed for use in the dental office.
