Examples of dentition with chronological eruption anomalies


Late eruption

Dental late eruption of 4 years in a young adult.

(A) Panoramic radiograph showing all the teeth in the mouth, including the 4 wisdom teeth (there is one lower left premolar missing) and the upper canines that are impacted and do not have enough space. On the pictures and the radiograph, the yellow asterisks indicate the permanent (definitive) canines and the blue ones indicate the temporary or primary canines. (B) The temporary canines are in the mouth and the upper left canine is trying to come out, but will not have enough space to come down and lodge itself in the arch.

Late eruption of many years in a 16-year-old teenager.

(A) Panoramic X-ray taken at 10.7 years of age. A late eruption is already visible. (B) Dentition and occlusion at 13.1 years of age, the late eruption continues. (C) At 16 years of age, the dental formation is normal despite the significant late eruption. It will still take several months for the teeth to shed naturally. See the above text for more details.
