In this study, the authors evaluate the accuracy of extent and severity estimates from PMPE protocols in a Chinese population.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Methods:<\/jats:bold>\n                    The study enrolled 200 individuals with periodontitis, ages 22 to 64 years. Full\u2010mouth examination was performed to determine probing depth (PD), attachment loss (AL), and bleeding on probing (BOP) at mesio\u2010buccal (MB), mid\u2010buccal (B), disto\u2010buccal (DB), mesio\u2010lingual (ML), mid\u2010lingual (L), and disto\u2010lingual (DL) sites per tooth. Extent and severity estimates from 15 PMPE protocols were derived from and compared to full\u2010mouth data. Relative bias (RB) and intraclass correlation coefficients (ICCs) were calculated. Bland\u2010Altman plots were used to evaluate the agreement patterns across disease levels.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:<\/jats:bold>\n                    Of the 15 PMPE protocols, the random half\u2010mouth six\u2010sites per tooth (r6sites) protocol performed best in both extent (AL \u22652, \u22654, or \u22656 mm; PD \u22654 or \u22656 mm; and BOP) and severity (AL and PD) estimates, with RB within 5.0% and ICCs \u22650.950 in most cases. MB\u2010B\u2010DB and MB\u2010B\u2010DL protocols generally resulted in RB within 20.0% for extent and within 5.0% for severity. Protocols involving only interproximal sites (MB\u2010DB, MB\u2010DL, and MB\u2010DB\u2010ML\u2010DL) showed good accuracy in AL (RB within 20.0% for extent and within 3.0% for severity), but overestimated PD (RB 12.5% to 54.2% for extent and &gt;10.0% for severity). The community periodontal index teeth protocol caused severe overestimation of up to 110.4% for extent and 14.6% for severity.\n                  <\/jats:p>\n                  <jats:p>\n
