Our Task
Asim W.
Sara I.
Fatima A. A.
Faculty Advisors:-
A critical review of tissue engineering and its
impact on dentistry, presented as a scientific
poster at the 1st IADSR International Dental
Conference.
Participation in the scientific poster competition.
3. A review of 15 different studies
conducted by eminent researchers in
the field of tissue engineering.
A brief introduction to tissue engineering,
and the creation of a diagram illustrating
its basic principles.
A discussion of its therapeutic viability
and an evaluation of its future prospects.
4. Tissue Engineering: an interdisciplinary field that applies the knowledge
of engineering, life sciences, cells culture, biomaterials and suitable
biochemical factors toward the development of biological substitutes to
regenerate or create damaged tissues and artificial organs and tissues[1].
Dental TE relies on the in-vitro recreation of the genetic odontogenic
programme using stem cells approaches
5. Dental stem cells
(SCs): undifferentiated
totipotent, pluripotent or
multipotent cells of
mesenchymal or
epithelial origin.[4]
Growth Factors:
regulatory substances
that stimulate cell
growth, proliferation and
differentiation; examples
include bone
morphogenic proteins. [5]
Scaffold: an artificial
structure capable of
supporting 3-D tissue
formation. [6]
Bioreactor: any
engineered device or
system that supports a
biologically active
environment.
6. Current research efforts focus on the characterization
and identification of dental stem cell population,
development of scaffold materials and growth factor
release technologies, and experimental design.
Researchers have seeded cultured tooth germ cells
on bio-degradable scaffolds which were then
implanted to bioengineer tooth tissues [2].
Animal trials have been highly successful though
human trials have met with limited success.
Ethical issues may arise concerning the source of
cells (patient’s own vs. donated cells) and the type
of cells (adult-donor vs. fetal cells). In addition, there
is a real possibility that dental tissue engineering will
be achievable to allow individuals to grow teeth insitu.
7.
TE principles are being
applied to the
regeneration of nearly
all oral tissues, including
periodontal tissues.
Scientists have been
able to generate tooth
structures from nondental mesenchymal
cells placed in contact
with embryonic oral
epithelium and
transplanted to an
ectopic site [3] .
Test-tube teeth may
become the first
completely engineered
human organs.
It is expected that in a
few decades rapid
scientific and
technological
advancements will
provide new solutions to
allow tissue engineered
tooth a routine practice
for missing teeth.
