Implication

Diagnostic accuracy study demonstrates reliable gingival thickness measurements using dental MRI in orthodontic patients, suggesting a radiation-free imaging alternative.

Key Points

To present the first measurements of gingiva thickness around lower anterior teeth using dental MRI and compare them with periodontal probing and superimposed cone-beam computed tomography (CBCT) with intraoral scans.
Consecutively enrolled 10 patients with anterior mandibular crowding and substantial orthodontic treatment need.
Assessed gingival phenotype via periodontal probing, followed by CBCT, intraoral surface scanning, and dental MRI using a 15-channel mandibular coil.
Mean gingiva thickness was 0.72 mm on MRI versus 0.97 mm on CBCT, showing a mean difference of 0.17 ± 0.27 mm (p < 0.001).
Agreement with clinical probing was 64.94% for MRI and 47.02% for CBCT.
Teeth with thin phenotypes had lower soft-tissue dimensions than thick phenotypes in both free gingiva (MRI: 0.56 mm vs. CBCT: 0.79 mm) and supracrestal gingiva (MRI: 0.75 mm vs. CBCT: 1.03 mm), with only MRI showing statistically significant differences between phenotypes.
