Final answer:
Registered Dental Assistants can apply bleaching agents under general or direct supervision, depending on state regulations. General supervision does not require the dentist's presence, whereas direct supervision does. The use of peroxides is common in the bleaching process, with professional application being more effective.
Step-by-step explanation:
A Registered Dental Assistant (RDA) is permitted to apply bleaching agents under general or direct supervision depending on the regulations of the state or country. Under general supervision, a dentist does not need to be physically present in the office during the application of bleaching agents. Conversely, direct supervision requires the dentist to be present in the treatment area to approve the work being done by the RDA and to be available to respond to any complications or emergencies that may arise.
The process of teeth bleaching generally involves the use of chemical preparations containing peroxides to whiten teeth, which is more effectively done in a dentist's office. While 'teeth-whitening' toothpastes are more accessible for daily use, they may not be as effective as treatments applied by dental professionals. Regardless of the method used, it's important for RDAs to follow proper protocol to ensure patient safety and the efficacy of the procedure.
