Summary
The COVID-19 prevalence in Czech dentists was 25.4%, with a lower PCR-verified positivity (13.9%) than the general population. Dental professionals
Area of Science:
- Dentistry
- Infectious Diseases
- Epidemiology
Background:
- Coronavirus disease (COVID-19), caused by SARS-CoV-2, poses risks to healthcare professionals.
- Dental professionals face potential occupational exposure to SARS-CoV-2.
Purpose of the Study:
- To evaluate the prevalence of COVID-19 among members of the Czech Dental Chamber.
- To compare COVID-19 positivity in dentists with the general Czech population.
- To assess the infection-hospitalization ratio (IHR) and identify contagion sources within dental practices.
Main Methods:
- An online questionnaire was distributed to 2716 members of the Czech Dental Chamber.
- Data collected included self-reported COVID-19 diagnosis, PCR-verified positivity, and perceived contagion sources.
- Prevalence and IHR were analyzed across different age groups and compared to national data.
Main Results:
- Overall COVID-19 diagnosis prevalence was 25.4%; PCR-verified positivity was 13.9%, statistically lower than the Czech general population (~15.6%).
- The work environment was identified as a contagion source by 38.4% of respondents, with nurses/dental assistants most frequently diagnosed.
- The infection-hospitalization ratio (IHR) was 2.8%, higher in older age groups (8.7% for >60 years).
Conclusions:
- Despite occupational risks, dentists in the Czech Republic showed lower PCR-verified COVID-19 positivity compared to the general population.
- Effective antiepidemic measures implemented by dental professionals appear to mitigate SARS-CoV-2 infection risks.
- Dental staff, particularly nurses and assistants, are frequently affected, highlighting the need for consistent safety protocols.

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):
