% assessment of the amount of plaque on dental surfaces; it is detected on 4 surfaces: distal, mesial, vestibular, lingual / palatal. The number of sites with plaque is divided by the total number of sites available in the mouth and multiplied by 100. Results indicate the index as a percentage.

Scoring criteria

Grade 0: oscillation within 0.2 mm; the teeth move naturally and there are no mobility problems; Grade I: horizontal mobility of the tooth from 0.2 to 1 mm; Grade II: horizontal mobility of the tooth from 1 to 2 mm; Grado III: horizontal mobility equal to or greater than 3 mm or vertical mobility of the tooth.

Scoring criteria (one measurement for each tooth: upper first incisors, first premolars/first primary molars and first molars):

0. Absence of inflammation

Mild inflammation (marginal or papillary unit) Mild inflammation (entire marginal and papillary unit) Moderate inflammation Severe inflammation
