California Registered Dental Assistant (RDA) Written Practice Exam

Digital radiographic sensors cannot be heat sterilized, meaning that they cannot be disinfected by heat in an autoclave. Only cleaning the sensors (choice A) is not sufficient to eliminate contamination. While immersing in high-level disinfectant (choice C) may effectively eliminate contamination, it is not recommended as it may damage the sensors. Avoiding using the sensors altogether (choice D) is not a feasible solution, especially in a clinical setting where they are necessary for patient care. Therefore, it is recommended to use impervious barriers to protect the sensors followed by cleaning and disinfection (choice B) to ensure effective and safe management of contamination.
