Assessment of Gingival Thickness Using Colored Periodontal Probe

Study Overview
=================
Brief Summary
-----------------
the accuracy of different assessment methods of the gingival tissue thickness can be controversial affecting their correct classification and the techniques of gingival tissue management in case of mucogingival problems. Aim: The aim of this study is to evaluate the accuracy of different assessment methods of measuring GT and to classify into the different gingival phenotypes.

Detailed Description
-----------------
The accuracy of different assessment methods of the gingival tissue thickness can be controversial affecting their correct classification and the techniques of gingival tissue management in case of mucogingival problems. The aim of this study is to evaluate the accuracy of different assessment methods of measuring GT and to classify into the different gingival phenotypes. Periodontally clinically healthy patients will be recruited from the Dental Clinic Complex (MIU) according to eligibility criteria. The gingival tissue thickness will be measured using probe-colored periodontal probes (CPP), standard periodontal probes (SPP) and transgingival sounding with an endodontic file (ISO #20), visual judgment using photographs will be done to the three assessment methods. All readings including GT (1ry outcome) as well as keratinized tissue width and probing depth will be carried out by three calibrated outcome assessors. Data collected will be tabulated and statistically analyzed.

After application of local anesthesia gel an endodontic file (ISO 20) with a rubber stopper will be inserted perpendicularly into the buccal aspect of the gingiva (1 mm below the gingival margin) until it touches the tooth surface. The insertion depth will be ensured through placing the rubber stopper in contact with the gingiva and fixing its position and the distance between the tip and the rubber stopper will be calibrated using a manual calibration device (endodontic ruler).<br>|
