Teeth

1.5K
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 Availability Heuristic

6.8K
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):

Tooth Anatomy

1.8K
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...

Issues And Trends In Healthcare Delivery System

6.1K
The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...

Summary

Front-line dentists face high infection risks from COVID-19. Implementing infection control protocols and postponing non-emergency care can significantly disrupt virus transmission in dental settings.

Area of Science:

  • Dentistry
  • Infectious Diseases
  • Public Health

Background:

  • The COVID-19 pandemic, caused by the novel coronavirus SARS-CoV-2 (formerly 2019-nCoV), presents significant challenges to healthcare settings.
  • Dental professionals are at high risk of exposure to infectious agents due to close patient contact and potential exposure to blood and saliva.

Purpose of the Study:

  • To inform front-line dentists about the COVID-19 pandemic.
  • To provide a protocol for managing potential exposure to SARS-CoV-2 in a dental clinical setting.
  • To outline infection control measures relevant to dental practice during the pandemic.

Main Methods:

  • This paper is an essay synthesizing available information on COVID-19.
  • It reviews general information on coronaviruses, pathogenesis, clinical manifestations, and diagnosis.

  • It applies international guidelines to develop a management protocol for dental settings.

    • Main Results:

    • Face-to-face communication and exposure to bodily fluids increase infection risk for dental care workers.
    • There is a high risk of cross-infection in dental practices during the COVID-19 pandemic.
    • Specific infection control measures, including mouth rinses, rubber dam isolation, anti-retraction handpieces, disinfectants, and waste management, are crucial.

    Conclusions:

    • Dentists play a critical role in interrupting the transmission of SARS-CoV-2.
    • Postponing non-emergency dental care for all patients is a key strategy to reduce transmission.
    • Adherence to updated infection control protocols is essential for protecting dental professionals and patients.
