When assessing the risk for infection in dentistry, a risk assessment should be performed. Of the items listed, which would be the final step in the process?





Correct Answer:
"record what you find."
when conducting a risk assessment in the context of infection control within dentistry, it is crucial to follow a structured and systematic process. this ensures that all potential risks are identified and adequately managed to protect both dental professionals and patients. the risk assessment process typically involves several key steps, as outlined below:

**stage 1 - "look for the hazards."** the first step involves identifying the potential sources of infection within the dental setting. this could include contaminated instruments, improper sterilization practices, or the transmission of pathogens through aerosols and droplets. by thoroughly examining the workplace, dental professionals can pinpoint specific areas where infectious hazards exist.

**stage 2 - "identify who is at risk."** after identifying the hazards, the next step is to determine who might be at risk of exposure. this includes not only the dental professionals, such as dentists, dental assistants, and hygienists, but also the patients who visit the clinic. each group might face different levels of risk based on their interaction with the identified hazards.

**stage 3 - "determine the level of risk."** this stage involves evaluating how likely it is that the identified hazards could lead to an infection and the potential severity of that infection. factors such as the virulence of the pathogen, the duration of exposure, and the susceptibility of the individuals at risk are considered. this assessment helps in prioritizing the risks and determining the necessary control measures.

**stage 4 - "record what you find."** documentation is a critical step in the risk assessment process. recording the findings provides a formal account of the hazards identified, who is at risk, and the level of risk associated with each hazard. this documented record supports transparency and ensures that all team members understand the risks and the measures that are in place to mitigate them. it also serves as a reference that can be used for future assessments or to demonstrate compliance with regulatory requirements.

**stage 5 - "review your assessment."** the final stage involves regularly reviewing the risk assessment to ensure that it remains up-to-date and continues to reflect the current conditions in the dental practice. new equipment, changes in procedures, or recent health incidents can all affect the risk landscape. regular reviews help in adapting the risk management strategies to any new circumstances, thereby maintaining a high standard of infection control.

by following these steps, dental practices can effectively manage the risks associated with infections, ensuring a safer environment for both staff and patients. the documentation of the findings, as highlighted in stage 4, is essential as it not only records the outcomes of the risk assessment but also sets the stage for continuous monitoring and improvement of infection control practices.
