When the x-ray beam is directed through a relatively long expanse of the structure, the lamina dura appears
radiopaque and well defined. When the beam is directed more obliquely, the lamina dura appears more diffuse
and may not be discernible.
Alveolar crest
within 1.5mm of CEJ
Continuous with lamina
dura

• Usually thinner in the middle of the root and slightly wider near the alveolar crest and root apex
