When assisting with a tooth extraction, which task is the RDA permitted to perform?
Answer: Applying pressure with gauze after the extraction
Applying post-extraction pressure with gauze to control bleeding is a supportive task within the RDA's scope; the other listed tasks require a dentist's authorization or licensure.
An RDA is charting during a dental examination. The dentist calls out 'MOD' on tooth #19. What does this abbreviation indicate?
Answer: A mesial, occlusal, and distal surface restoration or caries
MOD refers to the mesial, occlusal, and distal surfaces of a tooth, indicating involvement of those three surfaces in a restoration or caries lesion.
How should an RDA respond if a patient discloses they are taking a blood thinner medication that was not on their chart?
Answer: Note it in the chart and immediately inform the dentist before treatment begins
Documenting the update and alerting the dentist before any procedure ensures the treatment plan is adjusted to account for bleeding risk.
Which standard precaution must an RDA take when handling extracted teeth?
Answer: Treat them as potentially infectious and use PPE during handling
Extracted teeth are considered potentially infectious biohazardous material, requiring PPE and proper disposal according to OSHA and state regulations.
The dentist places a rubber dam before performing a root canal. What is the primary reason for using a rubber dam in endodontic treatment?
Answer: To prevent aspiration of files and irrigating solutions
Rubber dams isolate the tooth and protect the patient's airway from small endodontic instruments and chemicals such as sodium hypochlorite.
An RDA is assisting with a pediatric patient who refuses to open their mouth. What is the most appropriate next step?
Answer: Use tell-show-do technique and alert the dentist if the child remains uncooperative
Tell-show-do is a recognized behavior management technique for children; escalating to the dentist ensures appropriate management decisions are made by the licensed provider.
Before sterilizing dental instruments, why is pre-cleaning or scrubbing essential?
Answer: To eliminate organic material that can shield microorganisms from sterilization
Organic debris such as blood and saliva creates a barrier that can prevent sterilizing agents from contacting and killing all microorganisms.
