Dental Assistant Practice Exam

What is the Spray-Wipe-Spray method used for?

1. Coding patient records

2. Cleaning and disinfecting dental treatment rooms (DTR)

3. Preparing patient meals

4. Conducting patient surveys

The correct answer is: Cleaning and disinfecting dental treatment rooms (DTR)

The Spray-Wipe-Spray method is specifically utilized for cleaning and disinfecting dental treatment rooms (DTR). This technique is essential in maintaining a safe and hygienic environment in dental practices, where the risk of cross-contamination and infection must be minimized. In this method, the first step involves spraying a disinfectant onto the surfaces to be cleaned, which helps to break down any contaminants. The second step, wiping, effectively removes debris, organic matter, and other potential pathogens from surfaces. Finally, the last spray ensures that the disinfectant remains on the surfaces long enough to eliminate any remaining microorganisms, providing a thorough and effective cleaning process. The other choices listed do not apply to the Spray-Wipe-Spray method. Coding patient records involves documenting patient information, which is unrelated to cleaning practices. Preparing patient meals pertains to food service rather than environmental hygiene in a dental office. Conducting patient surveys is focused on gathering feedback regarding dental services, which also does not involve cleaning procedures. Thus, the application of this method is critical for infection control in a dental setting.
