Correlation analysis of periodontal tissue dimensions in the esthetic zone using a non-invasive digital method

PURPOSE Direct intraoral scanning and superimposing methods have recently been applied to measure the dimensions of periodontal tissues. The aim this study was analyze various correlations between labial gingival thickness underlying alveolar bone thickness, as well clinical parameters among 3 tooth types (central incisors, lateral canines) using a digital method. METHODS In 20 periodontally healthy subjects, cone-beam computed tomography images scanned files were obtained. Measurements at central canines performed points 0-5 mm from crest on superimposed images. Clinical including crown width/crown length ratio, keratinized width, scallop, transparency probe through sulcus examined. RESULTS Gingival level positively correlated with plate (P<0.05). incisors revealed strong correlation 1 2 mm, respectively, inferior gingiva line (G0), whereas G0 every in canines. No significant found hard or soft tissue thickness. CONCLUSIONS positive although identical depth levels not significant. under level, associated features, such form, width.
