TECHNIQUES USED IN EVALUATION OF GINGIVAL PHENOTYPE

Study Overview
=================
Brief Summary
-----------------
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.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Gingival phenotype<br>A Periodontal probe was used to differentiate between thick and thin phenotypes and Color coded Biotype Probe was used to classified the phenotype as thin, moderate, thick and very thick phenotypes. Endodontic File and Florida probe were used to measure the gingival thickness. | Device: Gingival thickness<br>* After the classification the phenotype, gingival thickness was measured with Endodontic File and Modified Florida Probe from the 3 different points. First point was the probing depth level, second one was 1mm apical to this level and third one from the 2mm apical to probing depth.<br>|
