Uses of cold plasma in conservative dentistry and endodontics

Abstract

A B S T R A C T Aim:To recapitulate the possible applications of non dentistry and endodontics. Objective: Non-thermal plasma is lately being researched for its applications in dentistry and cancer therapy. The objective of this review is to summarize the possible role of Non thermal plasma in conservative dentistry and endodontics. Background: Plasma is the fourth state of matter and also the most form, the other three being air, water and solid. Plasma is ionised form of gas and is of two types: thermal and non-thermal or cold atmospheric plasma. The cold atmospheric plasma based dental applications is being investigated recently in fields such as root canal disinfection, tooth whitening, sterilization, deactivation of oral biofilms, enhancement of strength of light cure restorations and cancer therapy. Reason: Cold atmospheric plasma may be of a great use in dentistry due to its properties. This review is to recapitulate and bring to light the possible uses of cold atmospheric plasma in conservative dentistry and endodontics.solid, liquid and gas are relatively well known. Plasma which is an ionised gas is considered as the fourth state of matter. It is found naturally (upper part of earth's atmosphere) and can also be produced artificially. It is neutral atoms and molecules 1 . Based on their temperature plasmas can be categorized into thermal plasmas (cold or low temperature). In thermal plasma, the component particles are in thermal equilibrium with each other. In non-thermal or cold plasmas the larger molecules comprising the gas, ions and atoms remain at low temperatures while the electrons are accelerated. Thermal plasmas are associated with electric sparks, flames, lightening, the sun and the stars. Cold plasmas are seen in fluorescent lighting tubes, neon tubes and plasma Plasmas operated at lower temperatures have attracted a lot of interest due to its use in applications such as surface film deposition and e. In the medical field, the use of non-thermal plasma in applications such as sterilization of living tissues, living objects for medical applications, blood coagulation, wound healing and tissue regeneration and . Apart from these applications, studies have been carried out to find out the possible uses of cold plasma in dentistry. The dental applications that have been experimented are inactivation of oral microorganisms associated with periodontal diseases, dental caries, root canal disinfection, surface modifications of dentine and implants, polymerization and tooth bleaching Cold plasma/ Non-thermal atmospheric pressure plasmaThe temperature of non-thermal plasma is 104ºF at the point of application. Energy is required to produce plasma. Electric, light or thermal energy can be used. Cold plasma can be produced using different gases such as Helium, Argon, Nitrogen, Heliox (a mix of helium and oxygen), and air. Some methods used to produce cold atmospheric plasma are Dielectric Barrier Discharge (DBD), Atmospheric Pressure Plasma Jet (APPJ), plasma needle, and plasma pencilThe non-equilibrium...

Awareness On Recent Advances in Gingival Retraction Materials During Impression Making Among Undergraduate Dental Students - A Questionnaire Survey

“…Previously our department has published extensive research on various aspects of prosthetic dentistry ('Evaluation of Corrosive Behavior of Four nickelchromium Alloys in Artificial Saliva by Cyclic Polarization Test:An in vitro Study', 2017; Ganapathy, Kannan and Venugopalan, 2017;Jain, 2017aJain, , 2017bRanganathan, Ganapathy and Jain, 2017;Ariga et al, 2018;Gupta, Ariga and Deogade, 2018;Anbu et al, 2019;Ashok and Ganapathy, 2019;Duraisamy et al, 2019;Varghese, Ramesh and Veeraiyan, 2019) (Mahendran et al, 2017;S et al, 2017;V et al, 2017), this vast research experience has inspired us to conduct a survey about awareness on recent advances in gingival retraction materials during impression making. Thus, the study aimed in finding out the awareness of recent advances in gingival retraction materials during impression making among UG students.…”
