Authors	Study design/subjects	Research question	Findings
Assaf et al. 2015 30	Seven participant (8–17 y), 12 teeth	Visualisation and measurement of revitalisation of the dental pulp after dental trauma using MRI; comparison of signal intensity of trauma affected and non-affected teeth	Reperfusion of pulp after dental trauma was diagnosed earlier with MRI compared to clinical examination Reperfusion occurred in majority of teeth that showed no clinical sign of vitality at 6 weeks, Normal pulp signal at 3 months correlated with clinical signs of vitality Pulp visibility was best with T 1W and T 1W fat-saturated sequences
Cankar et al. 2020 31	12 participants (34.4 + −7.3 y), 72 teeth	Quantification of dental pulp signal in teeth with caries; correlation between signal and extent of caries lesion	T2-maps with signal intensity of the dental pulp at different echo times were an indicator for inflammation Intact and affected dental pulps showed different T2 values; the extent of a caries lesion correlated to the intensity of the pulp signal
Juerchott et al. 2021 33	70 participants (three cohorts: 27.5 ± 3.1, 42.2 ± 11.6, 44.1 ± 14.6 y), 1585 teeth	Investigation of PCE patterns in dMRI in healthy teeth	No significant differences in PCE comparing age, sex and jaw type Minor but significant differences between tooth types PCE is a stable intraindividual marker for healthy and diseased pulp
Tesfai et al. 2022 32	Five participants	Comparison of intraoral coil with conventional head and surface coils and CBCT in terms of SNR and visibility	Acceptable scan time (5–7 min) Spatial resolution with intraoral coil comparable to CBCT Improvement of SNR in vivo with intraoral coil

CBCT, cone-beam CT; PCE, pulpal contrast enhancement; SNR, signal-to-noise-ratio.
