Why dental units have more bacteria than faucets do?
Explain why DUWLs contain more bacteria than faucets do. The public water source has a CFU count of less than 500/mL before entering the DUWLs; once that water enters the DUWLs and colonizes within the biofilm, the CFU count skyrockets.
How does dental unit water become so highly contaminated?

What are the occupational hazards of dental practice?
These include exposure to infections (including Human Immunodeficiency Virus and viral hepatitis); percutaneous exposure incidents, dental materials, radiation, and noise; musculoskeletal disorders; psychological problems and dermatitis; respiratory disorders; and eye insults. Percutaneous exposure incidents remain a main concern, as exposure to serious infectious agents is a virtual risk. Minimizing percutaneous exposure incidents and their consequences should continue to be considered, including sound infection control practices, continuing education, and hepatitis B vaccination. Basically, for any infection control strategies, dentists should be aware of individual protective measures and appropriate sterilization or other high-level disinfection utilities. Strained posture at work disturbs the musculoskeletal alignment and leads to stooped spine. The stooped posture also involved certain groups of muscles and joints. This may lead to diseases of the musculoskeletal system. Continuous educating and appropriate intervention studies are needed to reduce the complication of these hazards. So, it is important for dentists to remain constantly up-to-date about measures on how to deal with newer strategies and dental materials, and implicates the need for special medical care for this professional group.

How to breathe in during a dental exam?
In my personal experience, I’m not sure the pace matters as much as maintaining a consistent ratio of in-breaths to out-breaths. To keep things simple, try this 4-7-8 breathing technique. This involves breathing in for 4 seconds, holding your breath for 7 seconds, and then breathing out for 8 seconds. If this doesn’t feel quite right to you, you can try a different length of time, or a different ratio; everyone’s different. Most people like to breathe in through their nose and out through their mouth, expanding their belly with each in-breath; but again, this all comes down to personal preference.

We feel as though we are not getting enough oxygen when, in reality, we are getting too much oxygen. This is why breathing into a paper bag is such an age-old stereotypical remedy for soothing panic attacks; it soothes us by limiting our oxygen intake to a healthier pace.
