• Changes in contour/density of dentin
• Bone level around root
• Bone density & integrity of lamina dura
• Pulp chamber and PDL space
Examine the jaw
• If any lesion present, record its site, size,
shape, symmetry, borders, contents &
association with other structures
Attempt a diagnosis/ assess the need
