cating a new crown?
When we contour the crown so
the barreling in goes to the occlusal surface, the
patient can clean everywhere; there is no plaque
buildup. If we can stop short of the occlusal surface,
we find plaque accumulates and it is as

After biologic shaping, the furcation is replaced and
the area accumulates plaque.

restoration. The tissue has become inflamed from the
root being replaced because of plaque accumulation.
