AbstractCross-infection involves the transmission of microorganisms through secretions, bodily fluids and excreta, as well as undisinfected surfaces and medical equipment. In the dental office, diseases are transmitted via various routes, e.g. from patient to dentist or other member of dental team, from doctor or dental team member to patient, from patient to another patient, from dental office to community and from community to patient. The study was conducted to evaluate the effectiveness of infection control in dental practices based on the qualitative and quantitative assessment of microbiological contaminants detected on the surface of filling material packaging used in dental offices. The material for research were 9 packages containing dental materials during their use in 3 dental settings. The packages were placed in sterile flasks and rinsed to wash microorganisms from the surfaces. The washes were filtered through membrane filters and cultured under proper aerobic and anaerobic conditions, and at elevated CO2 concentration. Microbial growth on TIO and TSB media was observed. The contamination of most samples remained low as indicated by the growth from one to a maximum of five colonies on TSA. The contamination remained at the level of 10-50 CFU/package, i.e. <100 CFU/single package. The tests evaluating the contamination of dental package surfaces with aerobic bacteria confirmed high hygiene standards observed in dental offices from which the packages were brought.

Covid 19 is considered to be a pandemic virus infection. SARS-Cov-2 causes it. It is a viral infection that is transmitted through aerosol and droplet contamination, cross-infection, etc. Dentists are at a higher risk due to this corona. It has affected daily routines of dentist's life as they are unavailable to run the clinic and attend to patients. Different search engines like PubMed, and Google Scholar was used. The questionnaire consisting of twenty questions was prepared by using online survey google forms and circulated among the participants. SPSS software was used to evaluate the results and data collection. Statistical analysis was done by chi-square test. Later, results were being tabulated. This survey that is taken among dental students, dentists, and random public, it is seen that the majority of them are well aware of this recent pandemic attack. (COVID-19). It is concluded that dentists are affected to a significant extent due to coronavirus as their daily routine is affected severely. This study aims to identify the effect on dentist life on a routine basis due to the pandemic COVID - 19.

For students, who spend most of their time in school classrooms, it is important to maintain indoor air quality (IAQ) to ensure a comfortable and healthy life. Recently, the ventilation performance for indoor air quality in elementary schools has emerged as an important social issue due to the increase in the number of days of continuous high concentrations of particulate matter. Three-dimensional numerical analysis has been introduced to evaluate the indoor airflow according to the installation location of return diffusers. Considering the possibility of the cross-infection of infectious diseases between students due to the direction of airflow in the classroom, the airflow angles of the average respiratory height range of elementary school students, between 1.0 and 1.5 m, are analyzed. Throughout the numerical analysis inside the classroom, it is found that the floor return system reduces the indoor horizontal airflow that causes cross-infection among students by 20% compared to the upper return systems. Air ventilation performance is also analyzed in detail using the results of numerical simulation, including streamlines, temperature and the age of air.
