This study evaluates the 4 different techniques used in clinical measurement of gingival phenotype. 1) Tranclusency of UNC-15 Periodontal Probe, 2) Transgingival probing with Endodontic file (#20), 3)Transgingival Probing with Modified Florida Probe and 4) Translucency Colorvue Biotype Probe.

The aim of our study is to evaluate the reliability and applicability of the current examination methods recommended in order to improve the deficiencies of the traditional examination methods used in the evaluation of the gingival phenotype.
