SUMMARY:
Intraoral ultrasonography (US) can generate real-time images in a less traumatic and painless manner for the patient without using ionizing radiation, making it ideal for exploring superficial tissues such as the gingival tissue. Objective: To evaluate the accuracy of intraoral ultrasonography in determining gingival phenotype in patients with gingival recession. Materials e Methods: This is a diagnostic accuracy study involving a sample of 24 patients with RT1 gingival recession. Patients underwent gingival phenotype analysis using transgingival measurement (TGM) (reference standard) and intraoral ultrasonography (index test). Statistical analysis included Bland-Altman plot, Cohen's kappa coefficient (k), intraclass correlation coefficient (ICC), paired t-test, and Pearson's correlation. Results: Twenty-four individuals participated in the study, with most being male, and a mean age of 30.25 years. Twenty-three individuals had recessions in premolar teeth. The mean gingival thickness determined by USG was 0.99±0.27 mm, while MTG was 0.78±0.22 mm. ICC=-0.434 (p=0.862); k=-0.048 (p=0.754). The mean difference between the methods was -0.20, with a limit of agreement between 0.57 and -0.97. Conclusion: Ultrasonography proved to be a method of low reliability, and a lack of agreement compared to transgingival measurement in determining gingival thickness.
