Which statement best describes the overall oral hygiene pattern reported for the three patients?

• A. All three brush twice daily with fluoride toothpaste and none floss or interproximal cleaners.
• B. All three use manual toothbrushes with hard bristles.
• C. All three use a power toothbrush with round head and brush a couple times daily; none use floss or interproximal cleaning aids.
• D. All three only use mouthwash

Answer: (C)

The main idea here is identifying a brushing pattern that combines the type of brush, how often brushing occurs, and whether flossing or interproximal cleaning is used. The best description is that all three patients use a power toothbrush with a round head and brush about twice daily, with no floss or interproximal cleaning aids. A power toothbrush with a round head is associated with more efficient plaque disruption for many users, and brushing twice daily is a common, evidence-supported routine for maintaining oral hygiene. The absence of floss or other interproximal cleaners suggests interproximal plaque isn’t being addressed, which is an important part of a full hygiene plan, but the statement still best fits the reported pattern across the three patients. The other options don’t fit because they either describe manual brushes with hard bristles, or a mouthwash-only routine, or omit the key element of using a power toothbrush with a round head.
