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.

Due to the essential role of dentists in stopping the COVID-19 pandemic, the purpose of this review is to help dentists to detect any weaknesses in their disinfection and cross-contamination prevention protocols, and to triage dental treatments to meet the needs of patients during the pandemic. We used PRISMA to identify peer-reviewed publications which supplemented guidance from the center for disease control about infection control and guidelines for dentists. Dentists must triage dental treatments to meet the needs of patients during the pandemic. The ongoing pandemic has changed the practice of dentistry forever, the changes make it more cumbersome, time-consuming, and costly due to the possible pathways of transmission and mitigation steps needed to prevent the spread of COVID-19. Dental chairside rapid tests for SARS-CoV-2 are urgently needed. Until then, dentists need to screen patients for COVID-19 even though 75% of people with COVID-19 have no symptoms. Despite the widespread anxiety and fear of the devastating health effects of COVID-19, only 61% of dentists have implemented a change to their treatment protocols. As an urgent matter of public health, all dentists must identify the additional steps they can take to prevent the spread of COVID-19. The most effective steps to stop the pandemic in dental offices are to; vaccinate all dentists, staff, and patients; triage dental treatments for patients, separate vulnerable patients, separate COVID-19 patients, prevent cross-contamination, disinfect areas touched by patients, maintain social distancing, and change personal protective equipment between patients.

Objective. The purpose of the study is to evaluate the knowledge and universal application of decontamination methods of impressions in dental practices. Material and method. The study involved 131 persons (dentists and dental students at Faculty of Dental Medicine). All the participants completed a questionnaire regarding the knowledge of transmission risk and rates of infections agents through dental impressions and the importance of different methods of decontamination. Results. Most of the subjects (93.89%) are aware of classical safe standard to achieve infection control in dental office. The youngest ones are well instructed in dental school. Most of the participants concluded that ere is a risk of transmission of infectious agents through different devices (impressions, prosthetic components) are sent out of the practice. Still only 35.11% of the respondents use a decontamination process of impressions. Among these (46 subjects), only 25 of them follow a well-conducted decontamination protocol. Many of the subjects consider that the infections risk of dental devices is minor and the decontamination procedure only makes the technological process more difficult. Conclusions. Dental practitioners consider that there is a minor risk of person-to-person transmission of infectious through dental devices. Doctors and technicians as well do not use a multi-step process of decontamination, because it makes the workflow more difficult.

The current global coronavirus disease 2019 (COVID-19) outbreak is still exerting severe global implications, and its development in various regions is complex and variable. The high risk of cross-infection poses a great challenge to the dental practice environment; it is therefore urgent to develop a set of pandemic prevention measures to ensure dental practice safety during the COVID-19 outbreak. Therefore, we combined the epidemiological characteristics of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), public emergency measures for COVID-19, characteristics of dental practice, and relevant literature reports to develop a set of dynamic practice measures for dental practices in high-, medium-, and low-risk areas affected by COVID-19. This will help dental practices to achieve standard prevention and ensure their safe and smooth operation during the pandemic. It is hoped that these measures will provide a reference basis for dental hospitals and dental clinics in their care and pandemic prevention work.

Two diets formulated and offered for commercial fish production were examined to determine their microbial burden. The total count of aerobic bacteria ranged from 103 to 107 bacteria per gram of diet. The diets contained psychrophilic and thermophilic species and up to 104 aerobic and anaerobic spore-forming bacteria per gram. Enterococci and members of the Enterobacteriaceae, including species of Salmonella, were also present. Fluorescent pseudomonads were detected in 18 of the 47 samples tested, Proteolytic, amylolytic, lipolytic, and haemolytic organisms were shown to be present in measurable numbers. The total viable aerobic count did not change markedly on storage of representative samples at 4, 20, or 30 C.

Aspiration of the exudate through open perforation was performed in 54 children with chronic suppurative otitis media. Eighty aerobic and 81 anaerobic isolates were recovered. Aerobic bacteria only were involved in 20 patients (37%), and anaerobic organisms only in seven (13%). Mixed aerobic and anaerobic isolates were recovered from 27 patients (50%). The most common bacteria isolated were anaerobic gram-positive cocci, Bacteroides melaninogenicus group, Pseudomonas aeruginosa, Klebsiella pneumoniae, and Staphylococcus aureus. There were 45 β-lactamase–producing bacteria (BLPB), 30 aerobes, and 15 anaerobes recovered from 38 patients (70%). β-Lactamase activity was detected in 30 of the 38 ear aspirates (79%) that contained BLPB. All but one of these organisms were in excess of 104 colony-forming units/mL. The detection of β-lactamase activity in the ear aspirates provides evidence of the role of BLPB in the failure of penicillin therapy to eradicate chronic ear infection.

The Manual of Infection Prevention and Control provides practical guidance on all aspects of healthcare-associated infections (HAIs). It outlines the basic concepts of infection prevention and control (IPC), modes of transmission, surveillance, control of outbreaks, epidemiology, and biostatistics. The book provides up-to-date advice on the triage and isolation of patients and on new and emerging infectious diseases, and with the use of illustrations, it provides a step-by-step approach on how to perform hand hygiene and how to don and take off personal protective equipment correctly. In addition, this section also outlines how to minimize cross-infection by healthcare building design and prevent the transmission of various infectious diseases from infected patients after death. The disinfection and sterilization section reviews how to risk assess, disinfect and/or sterilize medical items and equipment, antimicrobial activities, and the use of various chemical disinfectants and antiseptics, and how to decontaminate endoscopes. The section on the prevention of HAIs reviews and updates IPC guidance on the prevention of the most common HAIs, i.e. surgical site infections, infections associated with intravascular and urinary catheters, and hospital- and ventilator-acquired pneumonias. In view of the global emergence of antimicrobial resistance to the various pathogens, the book examines and provides practical advice on how to implement an antibiotic stewardship programme and prevent cross-infection against various multi-drug resistant pathogens. Amongst other pathogens, the book also reviews IPC precautions against various haemorrhagic and bloodborne viral infections. The section on support services discusses the protection of healthcare workers, kitchen, environmental cleaning, catering, laundry services, and clinical waste disposal services.

Abstract Background Decision making when patients ask a dentist for fee reduction is a real ethical dilemma at dental settings. The aim of this study was to evaluate how dental students and tutors think about their position for, or against fee reduction at dental offices. Method It was a questionnaire-based survey, which examined the ethical attitudes of students and tutors of an Iranian Dental School. The questionnaire included a vignette about an ethical dilemma at a dental office. Different ethical approaches, i.e. duty-based, virtue-oriented and consequentialist arguments, for or against fee reduction at dental office were suggested. Respondents were asked to rank those ethical options. Data was entered and analyzed in SPSS 16.0. Result 121 dental students and thirty-six faculty members (dental specialists) participated in this study. It revealed that a majority of dental students and tutors (68%) are in favor of charging patients less, when facing an imagined request at dental office, using either virtue-oriented (54%) or consequentialist (14%) argument for fee reduction. The difference between rankings of four options was statistically significant, while no statistically significant difference exists neither between male and female respondents, nor students and tutors. Conclusion This case study provides a basis for fruitful discussions in ethics courses for dental students. Our study suggests that financial issues should be considered as a part of ethical training within the dental student's curriculum.

Fresh hamburger was packaged under vacuum or in air in films having different oxygen permeability and stored in a display case at 5 C for 30 days. Bacon was packaged with a laminated material, under vacuum, in air or carbon dioxide, and similarly stored. Aerobic and anaerobic bacterial counts were made at various intervals. In addition, bacon was examined for Clostridium perfringens and lactobacilli. Color changes also were evaluated. Bacterial numbers increased on hamburger with either packaging method. However, growth of aerobes on vacuum-packaged meat was slower than growth on meat packaged in air. Anaerobes increased in numbers in hamburgers in evacuated packages after 3 days in storage and after 6 days in meat in unevacuated packages. Packaging bacon in carbon dioxide resulted in reduction of total numbers of aerobes and lactobacilli. Few C. perfringens were recovered. Color retention was improved for as long as 30 days with either vacuum or CO2 packaging, as compared with air controls. In general, growth of anaerobes occurred earlier on fresh meat packaged under vacuum than in air; the converse was true for aerobic bacteria. Carbon dioxide inhibited bacterial growth on packaged bacon and provided good color retention during storage.
