Abstract
<Gingival biotype affects the outcome of restorative, periodontal and implant therapy significantly. The disparity in the outcome of treatment may be attributed to the variation in tissue
response to trauma. Therefore, detection of the periodontal biotype is critical in clinical practice.
Various invasive and noninvasive methods can be used to measure and assess gingival thickness.
Invasive methods include transgingival probing and direct measurement. The non-invasive
techniques are the visual inspection, probe transparency through the free gingiva, ultrasonic
devices, the modified caliper, Cone-Beam Computed Tomography (CBCT) and digital registration
superimposed method.
Different thresholds were suggested to differentiate between thick and thin biotype. They
suggested 1.5 mm, 1.2 mm, 1 mm and 0.75 mm thickness as the threshold between thick and thin
biotype. The present study suggested an arbitrary 1 mm threshold between thick and thin biotype.
The aim of the present study was the evaluation of the use of specially designed probe,
transgingival probing and probe transparency method versus cone- beam computerized tomography
in measurement of gingival thickness.
