Prosthetic restorations that have been tried in the patient's mouth are potential sources of infection. In order to avoid cross-infection, protocols for infection control should be established in dental office and laboratory. This study evaluated the antimicrobial efficacy of disinfectants on full metal crowns contaminated with microorganisms. Full crowns cast in a Ni-Cr alloy were assigned to one control group (n=6) and 5 experimental groups (n=18). The crowns were placed in flat-bottom glass balloons and were autoclaved. A microbial suspension of each type of strain - S. aureus, P. aeruginosa, S. mutans, E. faecalis and C. albicans- was aseptically added to each experimental group, the crowns being allowed for contamination during 30 min. The contaminated specimens were placed into recipients with the chemical disinfectants (1% and 2% sodium hypochlorite and 2% glutaraldehyde) for 5, 10 and 15 min. Thereafter, the crowns were placed into tubes containing different broths and incubated at 35ºC. The control specimens were contaminated, immersed in distilled water for 20 min and cultured in Thioglycollate broth at 35ºC. Microbial growth assay was performed by qualitative visual examination after 48 h, 7 and 12 days. Microbial growth was noticed only in the control group. In the experimental groups, turbidity of the broths was not observed, regardless of the strains and immersion intervals, thus indicating absence of microbial growth. In conclusion, all chemical disinfectants were effective in preventing microbial growth onto full metal crowns.

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.

SUMMARYNon-tuberculous mycobacteria are increasingly described as infectious agents in immunocompromised patients. A 17-year-old male patient suffering from secondary non-Hodgkin's lymphoma and treated with chemotherapeutic agents was admitted to hospital due to pleuropneumonia. Mycobacterium neoaurum was cultured repeatedly from his sputum and, Mycobacterium avium subsp. avium (M. a. avium) was detected by IS901 qPCR from detached fragments of his intestinal mucosa. We attempted to determine the possible sources of infection by analysing environmental samples from the closed oncology unit and conventional unit in the hospital, and from the patient's home residence and places which he frequented. The environment of the patient harboured mycobacteria (41 isolates in total); however, M. neoaurum was not recovered. M. a. avium was detected by qPCR in the environmental samples from a small flock of hens kept by his neighbour. Although it was not confirmed by DNA fingerprinting methods, the M. a. avium infection could have been acquired through the eating of incompletely cooked eggs.

Background: Although medical emergencies among dental patients are not frequent, several factors may provoke sudden cardiac arrests. Early initiation of high-quality chest compressions (CC) is of crucial importance for the safety and effectiveness of cardiopulmonary resuscitation (CPR). Aims: We aimed to evaluate the quality of chest compressions performed on a dental chair for the proposed procedure in case of cardiac arrest in a dental office. Methods: We designed a prospective, randomized, crossover simulation study. Sixty paramedic students were randomly assigned to the control group, in which resuscitation was performed on the floor (n = 30) or to the experimental group, in which compressions were performed on a dental unit (n = 30). We used a simulator that recorded number of compressions, rate, depth of compressions and chest recoil. Results: There were no significant differences in numbers, rate, depth of chest compressions or in chest recoil between groups. Conclusions: We proved that performing chest compressions on a dental chair might be as effective as on the floor. On this basis, we propose a procedure for safe and efficient performance of CPR in a dental office.

In the current COVID 19 pandemic, Dentists, auxiliaries as well as patients undergoing dental procedures are at high risk of cross-infection. Almost all dental procedures involve close contact with the patient’s oral cavity, saliva, blood and respiratory tract secretions. Saliva is rich in COVID 19 viral load. Many patients who are asymptomatic may be carriers. Hence, it is suggested that all patients who visit a dental office should be treated with all due precautions. Thus, the aim of this article is to provide a brief overview of the epidemiology, symptoms, and routes of transmission of this novel infection and protocol for patient screening, infection control strategies, and patient management.

AIM: This review aims to highlight the route of transmission, clinical features, diagnosis, prevention, and protection requirements for coronavirus disease (COVID-19) in dental clinics. MATERIALS AND METHODS: This review is built on specific protocol, two independent reviewers, each focused on articles related to COVID-19 and infection control in dental clinics, while the third independent reviewer resolved any conflicting article of interest. RESULTS: Respiratory droplets are the main routes of transmission of COVID-19. The main symptoms are fever, cough, and shortness of breath. Reverse transcription-polymerase chain reaction test on respiratory tract specimens is the most commonly used technique to detect COVID19. Combined nose and throat swabs and rectal swab are recommended to avoid false results. Personal protective equipment and evaluation are essential for every patient before starting any dental treatment, and following the instructions for infection control to avoid the spread of COVID19. In dental office, suspected patient with COVID-19 or presence of symptoms such as losing sense of smell and taste, in these cases dental treatment, must be postponed for 14 days. Evaluation of patient body temperature, screening, and answering questions related to contact COVID19 are crucial to make the decision to start or delay dental treatment to avoid COVID-19. CONCLUSION: Strict infection control procedures should be recommended. Patients recovered recently from COVID-19 may have treatment deferred for 28 days from onset of symptoms to avoid cross-infection. Anti-restrictive valves dental handpieces should be used to avoid cross-infection of COVID-19.

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.
