The effects of occlusal trauma may be evident on a radiograph as

A) a widening of the PDL space.
B) an excessive buildup of calculus.
C) dilacerations of the teeth roots.
D) furcation involvement.

A
Explanation: A) The effect of traumatic occlusion's excessive forces on the supporting bone can be observed radiographically as a widening or triangulation of the PDL space. The widening created appears as a radiolucent base with the apex pointing toward the apex of the tooth.
