CBCT diagnosis of impacted teeth and root resorption. CBCT, cone-beam computed tomography; EDAG, early dental age group; LDAG, late dental age group; LI, lateral incisor; RR, root resorption; 2D, panoramic imaging; 3D, CBCT.
| Authors | Sample size | 2D/3D | Results in accordance to CBCT |
|---|---|---|---|
| Durack et al. (19) | 10 | 2D + 3D | CBCT > 2D radiographs*: - Sensitivity - Specificity - Inter-examiner agreement |
| Goodell et al. (18) | 56 | 2D + 3D | Treatment plan on 2D differed with 3D in majority of cases |
| Patel et al. (17) | 15 | 2D + 3D | Correct treatment option: CBCT > intra-oral radiographs* |
| Ren et al. (20) | 160 | 2D + 3D | CBCT > 2D: Highly significant difference between periapical radiography and CBCT in detection of mild and moderate RR lesions (P < 0.05) |
| Tsolakis et al. (21) | 20 | 2D + 3D | CBCT more accurate diagnostic compared to 2D |
| Jawad et al. (16) | 42 | 2D + 3D | Improved RR detection rates of 63% with the use of CBCT |
| Hadler-Olsen et al. (22) | 59 | 3D | Best predictor for RR: if location of the canine mesial to the midline of the LI root in panoramic images |
| Lai et al. (14) | 134 | 3D | High accuracy of location, prevalence, and degree of RR with high interrater correlation |
| Sun et al. (23) | 41 | 3D | Roots of impacted teeth are significantly shorter than homonym teeth Roots of impacted teeth in EDAG shorter than in LDAG Dilaceration occurs mainly in LDAG |
