The accurate measurements are, thus, critical for optimal treatment planning and outcome evaluation. Present study aimed to introduce automated curvature-based digital gingival recession measurements, evaluate the agreement and reliability of manual measurements, and identify sources of manual variability.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>Measurement of gingival recessions was performed manually by three examiners and automatically using curvature analysis on representative cross-sections (n\u2009=\u200960). Cemento-enamel junction (CEJ) and gingival margin (GM) measurement points selection was the only variable. Agreement and reliability of measurements were analysed using intra- and inter-examiner correlations and Bland\u2013Altman plots. Measurement point selection variability was evaluated with manual point distance deviation from an automatic point. The effect of curvature on manual point selection was evaluated with scatter plots.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Bland\u2013Altman plots revealed a high variability of examiner\u2019s recession measurements indicated by high 95% limits of agreement range of approximately 1\u00a0mm and several outliers beyond the limits of agreement. CEJ point selection was the main source of examiner\u2019s variability due to smaller curvature values than GM, i.e., median values of \u2212\u00a00.98\u00a0mm<jats:sup>\u2212\u20091<\/jats:sup> and \u2212\u20094.39\u00a0mm<jats:sup>\u2212\u20091<\/jats:sup>, respectively, indicating straighter profile for CEJ point.
