A study of panoramic and periapical radiographs of 42 patients on haemodialysis and having renal osteodystrophy, demonstrated a progressive increase in periodontal disease, loss of lamina dura, deviation in the trabecular pattern, Brown tumor "pseudocyst" formation and pulp calcifications (Bandeira et al., 2006).
A distinct radiopaque line between the coronal and apical fragments made each fragment look as if it was separated by bone and surrounded by its own lamina dura. Based on these findings, the healing was classified as "healing by interposition of bone and connective tissue" according to the definition established by Andreasen and Hjorting-Hansen [8].
The radiographs were studied simultaneously by 2 dental radiologists for the presence of thickening of lamina dura, trabecular condensation and presence of radiopaque masses or areas.
Radiographically root development of 37 was complete, the lamina dura was continuous apically and the root canals were partially sclerosed.
