You would like to advise your patient to clean RPD
1) Early in the morning
2) Twice a day
3) After every meal
4) Thrice a day
Prosthodontics
Answer: 3
An RPD, or Removable Partial Denture, is a dental appliance that replaces one or more missing teeth. It is important to clean an RPD thoroughly after every meal to remove food debris and plaque, which can lead to dental issues like gum disease, decay of remaining teeth, and bad breath. Cleaning an RPD regularly helps maintain oral hygiene and the health of the patient's remaining teeth and gums. While it is generally recommended to clean it at least twice a day, cleaning after every meal is ideal to prevent the buildup of bacteria and food particles. The patient should also soak the RPD in a cleaning solution overnight to ensure thorough sanitization and maintenance of the appliance.
