Analysis of Missing-Tooth Patterns in Individuals with WNT10B Variants
| Quadrant | Central Incisor (%) | Lateral Incisor (%) | Canine (%) | First Premolar (%) | Second Premolar (%) | First Molar (%) | Second Molar (%) |
|---|---|---|---|---|---|---|---|
| Maxillary | 8/18 (44.4) | 15/18 (83.3)a | 12/18 (66.7) | 9/18 (50.0) | 10/18 (55.6) | 4/18 (22.2) | 6/18 (33.3) |
| Mandibular | 12/18 (66.7) | 15/18 (83.3)a | 8/18 (44.4) | 4/18 (22.2) | 14/18 (77.8) | 4/18 (22.2) | 5/18 (27.8) |
The numerator is the number of missing teeth in the nine individuals, and the denominator is the total number of teeth that these nine individuals should have at each position. The third molar (wisdom tooth) is not included. The tooth number on the left side is combined with that on the right side because no significant difference, in terms of the number of missing teeth, was found at any of the corresponding positions.
