Definition
What is it ?
01
Dr. Ghaliah Alsawah
An optical phenomenon
related to the presence
of sclerotic dentin in the
roots.
Butterfly Effect
Russel, A.A. et al, 2013

History
Chromopho-
bic sclerotic
dentin.
Butterfly
Effect
Beust Vasiliadis et al
1931 1983 And literature
still going ON !
Dr. Ghaliah Alsawah
Pattern
How usually does it occurs
02
Dr. Ghaliah Alsawah
The butterfly-shaped translucent dentin is
present always in a mesiodistal direction.
Sclerosed dentin is more translucent than
normal dentin.

The effect extension
03
Dr. Ghaliah Alsawah
-Sclerotic dentin first forms in the
mesiodistal direction starting from the
outermost and apical part of the root.
-With time, it progresses toward the inner
or pulpal area and simultaneously proceeds
in the coronal direction.

Significance
What role does it play ?
04
Dr. Ghaliah Alsawah
The formation of sclerotic dentin acts as a
natural protective mechanism, which is
an adaptation to the masticatory load
subjected to the tooth, but in the presence
of excessive force, the weaker nonsclerotic
dentin tends to fracture under the load.
Dr. Ghaliah Alsawah
Clinical
Implication
05
Dr. Ghaliah Alsawah
The literature consistently reports that root fractures
are more common in a buccolingual direction with
craze lines or cracks on root sections more common
buccolingually.
Von Arx T. et al, 2011
Thus, teeth with the butterfly effect may be weaker
buccolingually than mesiodistally, implying that
microcracks are more likely to form buccolingually.
Dr. Ghaliah Alsawah
Roots with effect have greater penetration of sealer
buccolingually. This can improve bacteria entombment
resulting in improved treatment outcome.
The performance of resin-based root canal sealers and the
cementation of root canal posts with some luting agents
might be influenced by the presence of the butterfly effect.
