StudentRDH Community Health And Research Principles Practice Test

In the PHP scoring system, what does a score of 0 indicate?

Debris in 1 section Debris in 2 sections No debris Debris in 5 sections

Correct Answer:

No debris

Explanation:

In the PHP scoring system, cleanliness on tooth surfaces is quantified by checking defined sections for debris. A zero means there is no debris detected in any of the assessed sections, indicating a clean surface. As debris is found in more sections, the score increases, showing reduced cleanliness. So a zero score directly corresponds to no debris. The other options describe debris present in sections, which would yield nonzero scores.
