Findings in curved mandibular tooth roots at different ages. Digital radiographs (lateral30°ventral - laterodorsal oblique projection, upper row) and sagittal CT-reconstructions (lower row) of mandibular teeth showing distal root shape in different ages. A/B: Caudal deviation of the distal root of a deciduous 08 in a 9 month old alpaca. C/D: Sclerotic changes in the alveolar bone and curved shape of the distal roots of 409 and 410 in a 31 month old llama. E/F: Distal 09 root in contact with mesial root of 10, there was no alveolar bone between the two neighboring teeth in this 61 month old alpaca. G/H: Deformed distal root of 09 and exposed root canal cavity in a 107 month old llama. Described findings are indicated with white arrows.
