A zone of partial destruction of the
connective tissue fibers
A zone of intact connective tissue
fiber attachment to cementum
A zone of complete destruction
A space of 0.1 to 0.2 µ containing
some granular material but no
recognizable fibrils, can be seen.
This is the “Cemental Cuticle”

Cervical root resorption or
idiopathic root resorption, and
its nature has not been adequately
elucidated
The root surface is covered with a
“cementum cuticle” formed
because of fiber destruction and
hypermineralization.
Cementum which has undergone
longer exposure shows a complete
covering of the normal projections
with what appears to be flat sheet-
like plaque and calculus
formations.
Plaque bacterial products have been
detected in the deep
surface layer
Bacterial lipopolysaccharide can be
identified at a distance of from
the surface of the periodontally
diseased roots
Invasion of bacteria, enzymes and
noxious products into cemental
matrix has been demonstrated in
periodontitis
The composition of the smear layer has
not yet been well defined*, but it
presumably reflects the composition of
the underlying cementum from which it is
produced.
The Ca/P ratio is 1.69 in normal cementum
vs 1.13** in smear layer over cementum.
