Question 344 · LDEK · Oral hygiene and diet
Select the answer describing the Aproximal Plaque Index (API), an index for assessing the bacterial plaque on proximal surfaces:
- A. it requires staining of plaque deposits.
- B. it requires plaque assessment on six index teeth: 55/16, 51/12, 63/24, 75/36, 71/32, 83/44 (primary and permanent teeth, respectively).
- C. a total score is calculated by adding the number of surfaces of plaque-covered teeth in relation to the number of buccal/labial surfaces and lingual/palatal surfaces of all teeth, and subsequently multiplying the result by 100 to arrive at a percentage.
- D. a total score is calculated by adding scores assigned to buccal/labial surfaces in quadrants 1 and 3 to the scores assigned to palatal/lingual surfaces in quadrants 2 and 4, and subsequently dividing the result by the number of examined surfaces.
- E. it is used for plaque assessment in the area of the tooth neck on four teeth surfaces (vestibular, lingual, mesial, distal).
Hint
Recall how Lange's approximal index is recorded: yes/no scoring of interdental areas after the plaque has been made visible.
