Measurement properties of gingival biotype evaluation methods

Background There are numerous methods to measure the dimensions of the gingival tissue, but few have compared the effectiveness of one method over another. Objective This study aimed to describe a new method and to estimate the validity of gingival biotype assessment with the aid of computed tomography scanning (CTS). Materials and Methods In each patient different methods of evaluation of the gingival thickness were used: transparency of periodontal probe, transgingival, photography, and a new method of CTS). Intrarater and interrater reliability considering the categorical classification of the gingival biotype were estimated with Cohen's kappa coefficient, intraclass correlation coefficient (ICC), and ANOVA (P
