Plaque was quantified planimetrically (percentage plaque coverage, P%) and using two plaque indices (Turesky modified Quigley\u2013Hein Plaque Index (TQHPI); Rustogi modified Navy Plaque Index (RMNPI)). Established Ramfjord (6 teeth\/12 surfaces) and Community-Periodontal-Index-of-Treatment-Needs (CPITN; 6 teeth\/12 surfaces or 10 teeth\/20 surfaces) subsets, optimised subsets derived from the observed plaque distribution to represent overall plaque levels, and additional subsets representing plaque-prone sites with elevated plaque levels were compared with full-mouth recordings. Performance was assessed using bias, root-mean-square error, intraclass correlation coefficients (ICC), and mixed-effects modelling.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>An Optimised-12 surface subset showed near-perfect agreement with P% full-mouth recordings (bias 0.03, ICC 0.962); the 12-surface CPITN revealed similar results (bias -0.07, ICC 0.967). The Ramfjord subset showed slight underestimation but high agreement (bias -1.23, ICC 0.970), whereas the 20-surface CPITN consistently overestimated full-mouth plaque (bias 4.33, ICC 0.839). A reduced 6-surface Ramfjord subset also preserved high agreement with full-mouth recordings (bias -0.76, ICC 0.954). For surfaces with elevated plaque levels, newly developed 12- and 6-surface subsets closely matched the elevated-plaque reference. Subset performance patterns were consistent across all oral hygiene stages and across plaque metrics (P%, TQHPI, RMNPI).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Except for the 20-surface CPITN, all subsets provided a robust approximation of full-mouth plaque.
