What is a common cause of static electricity in dental settings?

• A. Fractured equipment
• B. Inadequate sterilization
• C. Static electricity
• D. Improper patient positioning

Answer: (C)

Static electricity in dental settings often arises from the interaction of certain materials and the environment in which dental procedures take place. Materials commonly found in dental offices, such as plastic, rubber gloves, and various synthetic materials used for chair covers or equipment, can accumulate an electrical charge through contact and separation. This process is known as triboelectric charging and it can lead to the buildup of static electricity. The presence of static electricity can create discomfort for patients and may even interfere with the functioning of electronic dental equipment, making it critical to understand its sources. Environmentally, factors such as low humidity, which is common in many indoor settings, can exacerbate static electricity buildup. Other choices do not directly align with the concept of static electricity arising from material contacts or environmental conditions typically seen in dental practices.
