A. Endodontic Division
Endodontics covers a wide scope in modern dentistry. Patient
needs are increased with the increase of population. There is also a
direct or indirect communication between periodontal health and the
Increased rate of endodontic treatment must be supported by a
research plan that aims at improving root canal treatment. That is why
endodontic research plan must go in two directions; in-vitro studies,
and clinical studies which aim at supporting the new trend of evidence
based dentistry, or evidence based endodontics.
Purpose of the research plan:
This research plan aims at focusing on the new trends in Endodontics, and
relating it with the available treatment methods and equipments that support
research technology to reach better Endodontics.
Communication with other departments:
Endodontic research methodology necessitates communication and support
by different departments in the faculty of dentistry, medicine, science, high
institute of health, and college of agriculture and engineering.
These institutes can provide equipment, scientific support, and research
methodology that will definitely support reaching better refining of research
and give value to the obtained results.
The following explanations will focus on relating endodontic research
objectives with different branches of many scientific departments, colleges
1- The bacteriological aspects of Endodontics regarding the trials to
achieve a bacteria free environment in the root canal requires
consultation and cooperation with both the bacteriology department in
the faculty of medicine and high institute of health. It is well known that
one important objective of endodontic treatment is reaching a sterile root
canal. Improving research methodology should give an important
focusing on eliminating bacteria and micro-organisms from the root
canal. It is thought that such cooperation will lead eventually to better
2- New electronic devices that were introduced to Endodontics to
determine the exact termination point of the root canal are improving
and new devices are introduced every now and then to reach better
accuracy. These devices should be given a research attention.
Communication with the faculty of engineering and department of
biomaterials will give value to clinical evaluation and criticism to those
3- Introduction of new medications and irrigating solutions necessitates
studying of the biocompatibility of those materials and medications. The
anti- bacterial effect of such agents should also go parallel with their
cytotoxicity. Communication with bacteriology department in the
faculty of medicine and high institute of technology will help refining
4- Root canal preparation techniques has dramatically changed and
improved. Rotary instrumentation with its effect on canal deviation and
transportation should be meticulously studied. Their fracture resistance
when subjected to constraints inside the root canal should also be
weighed against their benefits. Research that seeks effect of rotary
instrumentation should have a special consideration.
5- Endodontic filing materials and sealers are increasing and improving
every now and then, their sealing ability both apically and coronally
should be evaluated. Micro leakage methodology requires cooperation
between endodontic researchers and biomaterial department as well as
faculty of engineering and science getting advantage of electron
6- Endodontic retreatment with the use of the endo microscope or
magnifying loops have changed the look to root canal anatomy,
increased the efficiency of endodontic microsurgery. We hope to get an
endodontic microscope to allow our researchers to perform researches on
micro endodontics, whether surgery or retreatment.
7- The portals of communication between endodontics and periodontics
open the door for a great cooperation between the two departments to
supply evidence based endodontics through clinical research.
8- Warm obturation techniques should have a great share in research since
they are considered one of the keys to successful endodontics. We
hereby express our needs to get such improved obturating materials and
techniques in our college which will add great value in the performance
and clinical experience of those who apply for master and diploma in
9- The common interest in endodontic posts after root canal treatment
requires great cooperation with the fixed prosthodontic division. Their
coronal sealing ability, their effect to strengthen or weaken the root
should also have a great attention.
10- The penetration of root canal sealers into accessory canals and
dentinal tubules gives rise to the need to focus on whether to remove or
keep the smeared layer, together with its effect on success and failure.
Hence the need for electron microscope studies with faculty of science or
agriculture which have such equipment.
11- Recent endodontic materials aim at strengthening the root after root
canal treatment. Mechanical testing in the department of biomaterials
will open the door for such studies.
12- Tissue regeneration and tissue engineering for treatment of pulpal &
periapical diseases .
In summary, the field of Endodontics has gained much interest in modern
dentistry, and the doors for new researches, materials, and techniques is
opened for different departments to scientifically cooperate for the sake of
better valuable researches.
