Rustogi Modified Navy Plaque Index [
carious teeth
CARIOUS TEETH, PLAQUE
The index divides buccal and lingual surfaces into nine areas (A to I) that are scored for the presence (score = 1) or absence (score = 0) of plaque. It is based on a dichotomous principle and assesses the presence of plaque on a whole mouth basis (areas A–I), interdental basis (areas D and F), and the gingival margin basis (areas A–C) and thus allows to evaluate each area separately. Third molars and carious teeth were excluded from the evaluation, whereas teeth with fillings, inlays, onlays, or crowns were included. RMPNI is calculated as percentage of biofilm adhering sites to measured sites.
