|---|---|---|---|---|---|---|---|
| Population | North American | Brazilian | Several regions | Saudi Arabian | Brazilian | Saudi Arabian | Chinese |
| CBCT scans (teeth) | 655 (1,137) | 807 (2,294) | 1,160 (2,305) | 208 (165) | 376 (633) | 300 (385) | 561 (1,024) |
| Tooth type | Premolars and molars | All types | All types# | Premolars and molars# | Maxillary first and second molars | Premolars and molars# | Premolars and molars# |
| Prevalence of PL | 59.5% | 88% | 55.5% | 74.5% | 77.7% | 15.84% | 56.1% |
| Prevalence of PL in teeth with MC | 82.8% | 98% | 82.6% | 90% | 45.7% | 85.4% | 79.0% |
| Odds ratio* | 4.38 | 6.25 | 4.4 | NA | 2.57 | NA | 3.658 |
| Tooth with the highest incidence of MC | Maxillary first molars (44.2%) | Maxillary first molars (54.5%) | Maxillary first molars (59.6%) | Maxillary first molars (40.6%) | Maxillary first molars (55.2%) | Maxillary second molars (38.1%) | Maxillary first molars (65.7%) |
| Root with the highest incidence of MC | MB root of maxillary first molars | MB root of maxillary first molars | MB root of maxillary first molars | MB root of maxillary first molars | MB root of maxillary molars | MB root of maxillary molars | MB root of maxillary first molars |
| Most frequently MC | MB2 canal of maxillary first molars | MB2 canal of maxillary first molars | MB2 canal of maxillary first molars | MB2 canal of maxillary first molars | MB2 canal of maxillary molars | MB2 canal of maxillary first molars | MB2 canal of maxillary first molars |
| * Probability of a tooth with a missed canal to be associated with periapical lesion; # excluding third molars. CBCT – cone-beam computed tomography; MB – mesiobuccal; MB2 – mesiobuccal second; MC – missed canal; NA – non-applicable; PL – periapical lesion. | |||||||
