Authors	Study design/subjects	Research question	Findings
Ruetters et al. 2018 42	5 patients (21 teeth)	Agreement of measurements of the periodontal bone support in periapical radiographs and MRI	High intra- and interrater agreement for measurements in radiographs and MRI; Strong correlation for both imaging methods; Clinical measurements may not be transferred to MRI, as cemento-enamel-junction is not visible on MRI
Juerchott et al. 2020 43	22 patients	Comparison of CBCT and MRI for the assessment of periodontal bone support in molar teeth (furcation involvement)	Excellent intra- and interrater agreement for MRI for the assessment of furcation involvement; High levels of agreement for MRI and CBCT
Hilgenfeld et al. 2018 44	5 volunteers	Reliability of MRI measurements of the thickness of the palatal mucosa	Assessment of palatal mucosa thickness and location of greater palatal artery highly reliable with MRI (mean intraobserver ICC 0.989, mean interobserver ICC 0.987)
Probst et al. 2021 45	42 patients (28–79 y, mean 56 ± 14.6), 34 healthy control (21–32 y, mean 23 ± 1.9)	Correlation of MRI findings and clinical findings in patients with generalised periodontitis	Bleeding on probing in at sites with probing depths ≤ 3 mm increases the risk of bone edema Size of osseous oedema at sites with healthy pocket depths (≤3 mm) and pathological conditions (>3 mm) was highly significantly different

CBCT, cone-beam CT; ICC, intraclass correlation coefficient.
