TECHNIQUES USED IN EVALUATION OF GINGIVAL PHENOTYPE

Not Applicable

Completed

• Conditions: Gingival Recession
• Interventions: Device: Gingival thickness

• Registration Number: NCT05478148
• Lead Sponsor: Ondokuz Mayıs University

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.

Arm && Interventions

Group	Intervention	Description
Gingival phenotype	Gingival thickness	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.

Primary Outcome Measures

Name	Time	Method
Feasibility and reliability of techniques	1 day	Comparison between the conventional techniques(Periodontal probe and Endodontic file) and modern techniques(Colorvue Biotype Probe and Modified Florida Probe) in terms of reliability and feasibility.

Secondary Outcome Measures

Name	Time	Method
The amount of gingival thickness and the width of the keratinized tissue	1 day	To determine the cut-off dimensions by evaluating the gingival thickness at 3 different points.
