Comparison of the Effectiveness of the USG and CBCT Combined With Intraoral Scanning Determing the Gingival Phenotype in the Healthy Periodontium

Gingival thickness was measured using UGTM method and CBCT/ CAD with PDIP technology at upper incisors and canines in three points localized midbucally : Free gingival thickness (FGT), supracrestal ( SGT) and crestal (CGT). Width of keratinized tissue was measured using periodontal probe calibrated for 1 mm. The gingival phenotype was determined by both methods according to the following criteria: GT ≤ 0,7 mm - thin gingival phenotype, GT \> 0,7 mm ≤ 1,0 mm - medium gingival phenotype, GT \> 1,0 mm - thick gingival phenotype. Toincrease the repeatability of the results, two researchers tested the same values twice on 2days interval between sessions.
