2. General information
characterized by deposition of
excessive amount of
cementum on the root surface
New tissue formation is in
direct contact with the
cementum of roots of teeth.
3. Types
• Localized—hypercementosis of single tooth. It is usually
a reactive, inflammation dependent phenomenon seen
on single tooth and usually in relation to periapical
osteitis or due to loss of occluding antagonistic tooth.
• Generalized—generalized hypercementosis affecting
many (all) teeth, but which is seldom recognized as such,
occurs with increasing age, i.e. as an age dependent
factor. It is also seen as a sign accompanying specific
diseases, as for instance, Paget’s disease of bone.
4. Aetiology
Loss of antagonist
Inflammation of the root
Trauma repair
Osteitis deformans or Paget's disease of bone
And others like hyperpituitarism, calcinosis, vitamin a
deficiency, rheumatic fever
5. Clinical features
Predominantly seen in adults
Permanent teeth are affected more commonly than deciduous teeth
In multirooted teeth one or more roots are involved
No sensitivity
Can cause fusion of the roots
Roots are larger in diameter than normal and present rounded apices
6. Radiographic features
There is
thickening and
apparent
blunting of root
with rounding of
apex
Apex appears
bulbous in some
cases
Lamina Dura will
follow the outline
of teeth in
normal
periodontal
ligament space
Irregular
accumulation of
cementum that is
accommodated
by related area of
bone resorption
