Agreement was evaluated using intra\u2010class correlation coefficient (ICC), Bland\u2013Altman analysis and mean absolute error (MAE). Generalised estimating equations and clustered ICCs accounted for within\u2010patient clustering. Subgroups included PD strata, bleeding, tooth type, calculus, restorations (prosthetic crowns\/orthodontic attachments) and smoking.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Ultrasound measurements showed high reliability (ICCs &gt;\u20090.90).
