Upon evaluation, it was noted that the patient was missing the maxillary and mandibular right and left primary canines (Figure 1).
The right bitewing radiograph shows a suspicious area mesial to the maxillary right first primary molar. Caries are noted on the distal surface of the mandibular right first primary molar.

Additionally, the right bitewing radiograph showed a suspicious area mesial to the maxillary right first primary molar (Figure 2). Caries were also noted on the mandibular left first primary molar and the mandibular right first primary molar (Figure 2).
This radiograph demonstrates a dysmorphic maxillary right primary canine erupting ectopically into the mesial aspect of the maxillary right first primary molar. This is probably the result of incomplete extirpation by a tribal leader.

A follow-up periapical radiograph of this region was obtained, which demonstrated an unerupted dysmorphic maxillary right primary canine tooth (53) positioned ectopically near the mesial aspect of the maxillary right first primary molar (Figure 3).
The tribal leader extirpated the lower left primary canine, but there appears to be a remaining tooth-like remnant.

It appears that the tribal leader failed to completely extirpate the developing upper right maxillary primary canine (53), and probably the lower left primary canine (73) due to the continued development of the upper right maxillary primary canine (53) and what appears to be a developing tooth-like remnant on the lower left primary canine area (73) (Figure 4).
The radiograph demonstrates the absence of the maxillary and mandibular left primary canines.

Additional radiographs confirmed the absence of the maxillary and mandibular left primary canines (Figures 5 and 6).
The periapical film confirms the absence of the primary maxillary left canine.
