Impact of Impaction on CBCT-Based Third Molar Maturity Index Accuracy at Age 18

This study investigates how impaction affects the accuracy of the third molar maturity index (I3M) in determining whether individuals have reached the age of 18 using CBCT scans. The research compared sensitivity, specificity, and AUC between impacted and non-impacted mandibular third molars, finding no significant difference in overall discrimination but noting that impaction alters the error pattern, particularly reducing sensitivity at the 0.08 cut-off.
