Why is it important to cover the exposure button with a sticky?

Covering the exposure button with a sticky is important to prevent contamination from hands. This is a crucial aspect of infection control in dental radiography, where the exposure button can be a vector for pathogens if not properly protected. Dental settings are prone to contamination due to the presence of saliva, blood, and other bodily fluids, so it's essential to minimize the risk of cross-contamination. By using a sticky cover, dental practitioners can create a barrier that helps maintain hygiene and ensures that instruments and surfaces remain as clean as possible between uses, ultimately protecting both the patient and the healthcare provider from potential infections.
