Abstract
Aim: To determine the degree to which trabecular bone contributes to the radiographic visibility
of laminadura (LD).
Study Design: Human dry mandibles were obtained, and a series of radiographs were acquired
in the premolar region. Radiographs taken were: (1) Before removal of any bone, (2) After
removal of small amount of cortical bone at the apex of tooth, (3) Removal of trabecular
bone, (4) Smoothing of endosteal surface of cortical bone. The radiographs were projected to
a panel of six oral radiologists, and they were asked to judge the visibility of LD.
Results: Chi‑square analysis revealed a significant radiographic difference between radiographs
made initially and after removal of trabecular bone, cortical bone and smoothing the endosteal
surface of cortical bone.
Conclusion: There was statistically significant difference in the visibility of loss of LD when
trabecular bone is lost. LD can be visible only if the endosteal surface of the cortical bone and
trabecular bone is intact.
