      Columbus, Ohio, USA.
The geriatric population (65+ years) is a rapidly growing segment of the population worldwide. In the U.S., they constitute approximately 14% of the total population, and this number will increase to 23% by the year 2040. Almost 6% of the geriatric population today resides in nursing homes. The demographic shifts caused by the increase in the percentage of elderly population will be affected even more by the advent of the baby boom generation into the next 12 years. The elderly population faces many challenges to acquire adequate oral health care. These problems include a shortage of trained professionals in geriatric dentistry. Therefore, oral health professionals must be cognizant of how to diagnose and manage oral conditions that occur commonly in this population. This presentation will review the current concepts of diagnosis and management of common oral conditions in the elderly including:

- Conditions affecting periodontium and tooth structure.
- Ulcerative lesions affecting oral mucosa.
- Denture-related conditions.
- Xerostomia (dry mouth).
- Conditions affecting the tongue.
- White lesions of oral mucosa.
- Malignant of oral mucosa.
- Vesiculobullous lesions of oral mucosa.
- Pigmented lesions of oral mucosa.

Abdel Rahim Mohammad, DDS, MS, MPH, FAAOM
     Professor of Geriatric Dentistry and Oral Medicine,
     Ohio State University College of Dentistry,
     Columbus, Ohio.USA.

There is no doubt that smoking is the single greatest preventable cause of death and illness. In the U.S., tobacco use causes roughly one death every 1.5 minutes. The total number of deaths worldwide related to tobacco use is estimated to be approximately 5 million. In Egypt, the cost of treating diseases due to tobacco use is estimated to be $545 million dollars annually (World Health Organization, 2004). WHO estimates that today 84% of worldwide tobacco users live in developing countries and it is expected to reach 1.7 billion in 2025. Tobacco smoke contains approximately 600 chemicals, including 200 considered poisonous and 43 known carcinogens. At least 25% of dental patients are tobacco users, with another 25% of dental patients are young people who should be encouraged not to begin use of tobacco products. Studies show that more than 80% of tobacco users want to stop. However, because of the highly addictive properties in tobacco products, many need professional intervention. This presentation will review:

- Physiological effects of tobacco products.
- Effects of long-term use of tobacco on general systems.
- Physiological and psychological effects after tobacco cessation.
- Tobacco induced oral conditions.
- Role of the oral health professional in tobacco cessation·
- Intervention for treating tobacco use including pharmacological therapy and behavioral modification.

Prof. Dr.Omar M. Fahim,
     Professor of Endodontics,
     Faculty of Oral & Dental Medicine, Cairo University.
     Endodontic Consultant, King Fahad General Hospital, Jeddah, Saudi Arabia

Endodontic therapy utilizing calcium hydroxide material had been changed since Herman in 1930s. Calcium hydroxide induced hard tissue formation, promotion of soft tissue healing, tissue dissolving capacity and anti-microbial action. On the other hand, controversy appeared with other new materials introduced to the field for each property with many questionable marks.

This lecture is directed:
to evaluate each property for calcium hydroxide material in different forms compared with other new materials,
To discuss the future of calcium hydroxide material.

5. Title: Bleaching of endodontically treated teeth: Safety & effectiveness of actual
    methods "

     Tony I. Chahine: BDS, CES Endo, DU DRE,
     Head of Restorative & Esthetic Dentistry, Faculty of Dentistry. Lebanese University, Lebanon

Bleaching products and related techniques became very popular between the general practitioners nowadays.
This increasing popularity for tooth bleaching has lead to the production of a wide variety of heat- , light- ,
and chemically-activated materials. Related techniques became easier and more convenient
for both dentists and patients, giving them the choice between a chair side single appointment
or ambulatory multi-session treatment.
The purpose of this lecture is to describe the mostly used techniques and to evaluate the ease-of-use,
effectiveness, and safety of each product.

6. Title: Treatment Planning: Endodontics, fixed partial dentures –
    or implants?
Tamer El-Gendy BDS, MS
     Assistant Professor, Implant Prosthodontics
     College of Dentistry, Ohio State University
     Columbus, Ohio, USA.


Endodontic therapy does not prevent future loss of the tooth from recurrent caries, periodontal disease, or root fracture. Endodontic therapy may extend the life of the tooth but very little is know on the extent of tooth longevity.

The alternative to endodontically treating a tooth is extraction, resulting in a space that can have a potential adverse effect if left untreated. The predictability of implants as a long-term solution for edentulous areas has improved to the point where they have become the standard of care in many situations. Most studies indicate very high success rates for implant therapy mostly greater than 90% , which appear favorable when compared to success rates of endodontically treated teeth and fixed partial dentures.

The clinician is then faced with treatment planning dilemma as to which form of therapy (implants vs. root canal vs. FPD) is best for their patient’s situation.

This presentation will describe various clinical scenarios highlighting whether treatment with dental implants, root canal treatment, or a FPD is the best scenario for the given patient. Outcomes and long-term prognosis for each given therapeutic option will be described.

Upon completion of this presentation, participants should be able to:
· Determine whether a dental implant, a root canal treatment, or a FPD is the appropriate treatment option for a given
  patient scenario.
· Identify the different success rates for implants, root canal treatment and FPDs.
· Identify when alternative types of therapies may be indicated when compared to implant or root canal treatment
  or FPD treatment options.

7. Title: Clinical Evaluation of Dycal and MTA as a pulp dressing
    in vital pulpotomy.

     Prof dr Mohamed Salem Rekab.
     Prof and Chairman Endodontic, and Operative Dentistry Dept, Faculty of Dentistry, Syria
     University, Damascus.

The aim of this study was to make a clinical and radiographic comparison between Dycal and MTA materials when used as pulp dressing in vital pulpotomy of young permanent molars. The results of this study showed the superiority of MTA (97.44%) over Dycal (84.62%)in aiding the healing of the pulp tissue after vital pulpotomy procedures.

The data presented will help dentist:
- To diagnose pulp condition and working out a simple procedure of protecting pulp and maintain its vitality.


8. Title: Two Year Clinical Experience With Surgical
    Microscope: Advantages and Pitfalls

     Ahmed Abdel Rahman Hashem, DDS, MSD, PhD.Lecturer of Endodontics,
     Faculty of Dentistry, Ain Shams University. Egypt.


Surgical Microscope or dental operating microscope as some like to call it has started to gain its place among the important tools used in Endodontics. Using the microscope has opened a new era of micro-endodontics and endodontic microsurgery. Advantages as conservative coronal access, easy identification of hidden and extra canals, removal of broken instruments, and identification of isthmi during retrocavity preparation are well established. On the other hand, in some situations, the surgical microscope is not that effective. Also, some limitations in its use have been noticed. This lecture will focus on the different advantages of surgical microscope. It will be augmented with clinical cases, where the microscope was of great help in resolving the problems encountered during their management.



9. Title: Root fracture: Treatment and Prognosis.
     Professor Dr Faisal Dayoub,
     Professor of Endodontics,
     Faculty of Dentistry, Syria University, Damascus.


Fractured anterior permanent teeth are common in childhood. Considerations in diagnosis of conditions in and around the involved tooth; a proper line of treatment is considered to treat tooth .The following presentation aimed at:

- Highlights methods of diagnosis of various forms of fracture.
- Consideration for maintaining pulp vitality if the roots is incompletely formed.
- Discussion of various factors that improve prognosis.

       Chairperson, Scientific Committee,
       Lebanese Dental Association,
       Former editor-in-chief of the Arab Dental Journal


Healing of periapical lesions remains to date the aim of endodontic treatments or retreatments. Despite many published studies, many factors remain unknown or misunderstood. Ignoring these factors will predictably lead to misadapted clinical behaviors. The aim of this presentation is to group available evidence-based information in order to answer the questions raised by dentists regarding the clinical options when in presence of infected teeth with periapical lesions, and the prognosis after treatment.


11.Title: Pain Control in Endodontics:
      Dr. Essam I. Zaatar ,D.D.S.,M.S.D.
      Chairman Endodontic Department,
      Ministry of Health, Kuwait, Board Member, Faculty of Dentistry,
      Kuwait Institute for Medical Specialization.
      Assistant Professor, Faculty of Dentistry, Kuwait University.


Pain is an unpleasant sensation created by noxious stimulus that is mediated along specific nerve pathway to the CNS. Studies have shown that 95% of patients seeking dental treatment because of pain are suffering from pain of pulpal origin. Pain is generally a symptom of an underlying problem, managing the symptom does not cure the problem. Our efforts should be aimed to prevent pain development or at least to intercept it.

Understanding the mechanism of pain is a prerequisite for managing it. The classical 3d’s approach for pain control (diagnosis, definitive treatment, and drugs) remains the treatment of choice. This presentation shall review the recent advances in:
- Theories of pain mechanism
- Different strategies in interruption of pain
- New generation of local anesthetics
- New injection techniques
- Microbiology of symptomatic teeth pain control drugs and related clinical applications.

        Mohamed Ragai El-Mostehy,BDS, MSD,Ph.D.
        Professor Emeritus, Oral Medicine, and Periodontology Departement.
        Faculty of Oral and Dental Medicine, Cairo University.


Several dental disciplines are intimately related to periodontics. A healthy periodontium will allow dental therapeutic procedures to give not only a favorable prognosis but could end up in a healthy dental apparatus both esthetically and functionally. Restorative dentistry and crown and bridge construction are two disciplines that could succeed or fail if the underlying periodontium is or is not in a full health. This presentation will discuss this issue on clinical premises. It will enlighten the audience as to the importance of the “biologic width” and its role is directing either to the good or bad outcome. It will discuss the surgical management of the following:

- Fractured teeth with the fracture line apical to the free gingiva of the traumatized tooth.
- Proximal cavities that have the gingival steps apical to the gingival margins of the carious tooth.
- Crown lengthening where an abutment is constructed on the inadequate short crown.


15. Title: The Role of Biologic Modulators in Perio-Endo Therapy
        Ahmed Gamal, DDS, MSD, PhD: Professor of Periodontology,
        Faculty of Dental Medicine, Al-Azhar University, Egypt.


A major goal of periodontal therapy continues to be regeneration of the attachment structure of teeth, including new bone, periodontal ligament, and cementum, which have been destroyed by periodontal or pulp diseases. Although a number of treatment modalities are clinically available, clinicians continue to seek more predictable regenerative therapies that are less technique sensitive and lead to faster tissue regeneration. Current studies using tissue engineering technologies and stem cells are making significant progress, and tissue regeneration may shortly become feasible for clinical application. This presentation will review current treatment modalities that involve the use of biological modulators, for more predictable periodontal regeneration of the critical sized perio-endo defects.

16. Title: Immunologic Aspects of Endodontic Cases
Professor Dr Abd El Fattah Amer, DDS, MSD, PhD: Professor of Periodontology, Faculty of Dental

       Professor Emeritus, Loyola University,
       Formerly Director of Post-Graduate Endodntics,
       Loyola University, School of Dentistry,
       Maywood Illinois. USA.


Tapered, rotary instruments have taken the endodontic community by storm. As useful as they are, the greatest problem is the instrument fracture in the apical third of the preparation. Studies indicate the even the experts are able to retrieve these separated files in only 33% of the cases, leaving the ultimate prognosis in doubt. This presentation will demonstrate the safest possible method for using these wonderful files and will illustrate long-term success of the method.

18. Title: Long-Term Evaluation of Endodontically Treated Teeth with Inadequate

Franklin S Weine , B.S,,DDS, MSD, FACD, FICD, Professor Emeritus, Loyola University Formerly Director of Post-Graduate Endodntics, Loyola University ,School of Dentistry, Maywood Illinois. USA.

A considerable number of investigators have examined the question of coronal seal. Most results indicate that the lack of this seal is a frequent cause of endodontic failure. I have had a number of patients return for recall from as long as 38 years post-treatment. These results indicate quite a contrary result. These cases and their evaluation will be examined.


19. Title: Endodontic Failures Revisited changing the Approach.
        Mohamed Fayad, DDS, MS. PhD.
        Clinical Assistant Professor,University of Illinois,
        Chicago, Illinois, USA


Endodontic treatment is the foundation of restorative dentistry. However, clinicians frequently encounter endodontically treated teeth that are failing. Endodontists often face the challenges to choose between non surgical and surgical retreatment. This lecture will review new philosophies in indications of re-treatment versus periradicular surgery. By utilizing innovative technologies, demonstration of how to manage certain retreatment challenges will be presented. This presentation will focus on the step-by-step techniques that may be utilized to guide each case to successful completion. The second half of the presentation is designed to provide the opportunity to learn about contemporary microsurgical armamentarium and techniques from flap design, reflection, root end preparation and filling to suturing.

Video presentations and demonstrations of techniques used during endodontic retreatment and periradicular surgery procedures will be utilized. Topics will include separated instrument removal, removal of carrier-based obturators, post removal, perforation repair and location of previously untreated canals.

At conclusion, participants should be able to:
- Utilizes micro sonic procedures to refine access cavities and locate missed canals.

       Dr. Ahmed Al Khtani
       Dr. Ahmed Al Khtani
       Assiatant Professor. King Saud University,
       College of Dentistry
       Department of Restorative Dental Sciences.


It is apparent that the preliminary objectives of operative endodontics are total debridment of the pulpal space, development of a fluid-tight seal at the

apical foramen, and total obliteration of the root canal. In 1924 Hatton indicated, "Perhaps there is no technical operation in dentistry or surgery where so much depends on the conscientious adherence to high ideals as that of pulp canal filling."

This presentation will reinforce the basic principles of root canal fillings and will discuss the various methods of root canal obturation with focus on vertical condensation technique, with presentation of various clinical cases with complicated anatomy obturated with this technique.


22. Title: Comparative Study of Root Canal Preparation Using
      Protaper Rotary

        Ni-Ti Instruments and NiTi Hand Instruments.
        Carlos Menezes Aguiar
        Universidade Federal de Pernambuco- Brazil


The two most important causes of fractures of files are torsion and flexural failures. Torsion fractures occur when
the tip or any other part of the instrument engages the root canal while the other part still rotates. Flexural failures
are those caused by metal fatigue, when the instrument is used in a canal with a small curve radius. The limit of
flexibility of the instrument is exceeded, thus resulting in fracture by cyclic fatigue Authors and manufacturers
have recommended many techniques of root canal preparation, with different instruments and engines. a technique
of biomechanical root canal preparation is described using ProTaper rotatory nickel-titanium instruments and
compare the root canal shaping abilities with nickel-titanium hand
- Important aspects on the utilisation of these instruments will be discussed, and
· A sequence of instrumentation is proposed,
· Aiming at the reduction of the risks of fracturing nickel-titanium files and root canal morphological alteration.


23. Title : Complication of Root Preparation
        Professor Dr Safouh El-Bunni,
        Professor of Endododontics,Vice Dean Scientific Affairs,
        Faculty of Dentistry,
        Syria University, Damascus.


In order to complete the endodontic treatment successfully we have to know the difficulties and failure case that we face it during treatment. Moreover if we want to talk about these difficulties we will need long hours; specifically cleaning and shaping will be considered .Attending the presentation will benefit from the following:
- Discuses the difficulties encountered in identifying the proper working length.
- Choosing the proper preparation procedure.
- In the mean time defining solutions for problems encountered with references to some preventive measures to avoid
  such problems.


24. Title: A survey of vital and non-vital tooth therapy for Milky

       Ismail Elsherif, DDS, MSD, PhD
       Professor of Endodontics - Alazhar University. Egypt.
       Assitant Professor of Endodontics – Loma Linda University, California, USA.


All teeth, even baby teeth, are important. Many parents, are under the false impression that baby teeth are less important because they will eventually be replaced. Good oral hygiene is essential to cavity prevention as it removes bacteria and the left over food particles they feast on. In the war against cavities, bacteria is public enemy #1. Millions of these bacteria live, work and play in our mouths. Here they feed on left over food particles, creating acid in the process. It is this acid by-product which eats into tooth enamel and causes cavities. Cavities: the modern horror for young kids. The truth is that with the proper knowledge and care, today's kids can remain virtually cavity free.

The most common dental emergencies include (1) teeth that have been knocked out due to trauma and (2) teeth that have been chipped as a result of an accident. In either case, it is important to know what to do.

With chipped teeth the situation is slightly more complicated. If your child is experiencing pain or sensitivity in the affected tooth; this indicates the tooth nerve may be injured. The dentist can perform a root canal or other necessary procedure to save the tooth. Afterwards, bonding material can be sculpted onto the tooth to replace the lost portion. A comprehensive coverage will be given and What should be done in case of emergency for:
· knocked out child's tooth.
· chipped child's tooth.
· exposed vital and necrotic pulp.

25. Title: Endodontic Access Cavity Preparation
        Dr. Essam I. Zaatar
        Chairman Endodontic Department, Ministry of Health, Kuwait, Board Member, Faculty of Dentistry, Kuwait
        Institute for Medical Specialization.
        Assistant Professor, Faculty of Dentistry, Kuwait University.

Modern endodontic therapy is based on debridment; disinfection and obturation of the root can system. The success formula essay, expensive and requires skillful clinician. However, it is our good fortunes that modern technology has tremendously allowed us to overcome the inherent difficulties while delivering the treatment.

Treatment planning in endodontic ranges from pulp capping to intentional replantation procedures. It is the careful evaluation of the case and the skill of the operator that dictates the suitable treatment with the aids of the modern technology only as a supplement and NOT a must!

It is agreed that accurate case selection, evidence based diagnosis and definitive treatment planning are prerequisite for endodontic treatment success.

This presentation is designed to provide the general dental practitioners with systematic clinical hints in each step of the phase of endodontic access cavity preparation. At the end of this presentation, the audience will realize that most iatrogenic complications associated with endodontic treatment could simply be avoided by establishing adequate access cavity preparation.


26. Title: The control of the canal taper uses the K3 Ni-Ti rotary

        Phylippe W Sleiman, D.D.S., M.SC.
        Member of the Advisory Council on Endodontics, USA


The ultimate goal of the Endodontic treatment is the elimination of the bacteria and its toxin, in order to prevent any infection or re-infection of the surrounding tissues. Mainly this is the role of the chemicals but in order to do so, we need to have an adequate reservoir that can accept and hold these irrigation solutions and that is one of the role of canal preparation.

Maybe it is more adequate to say shaping for cleaning. The placement of an hermetic seal inside the prepared canal system is one of the final steps of the Endodontic treatment. Shaping the root canal system with Ni-Ti rotary instruments using one sequence is not recommended due to the anatomic complexity of the root canal morphology. The VTTS or the variable tip taper sequence, can address the shaping of any canal by apical tip diameter or by the use of varying tapers. This technique will enable us to overcome most of the difficulties in order to prepare adequately the root system for a better cleaning and to accomplish a 3D obturation.

Over the years, there has been a tremendous improvement not only in endodontic filling materials, devices and techniques but also in obturation concepts. This presentation covers the different basic and advanced aspects of root canal obturation from the past and the present, up to the future.


33. Title: The Restoration of Endodontically Treated Teeth
        Dr Omar Zidan, DDS, MS School of Dentistry,
        University of Minnesota, USA.


The restoration of endodontically treated tooth is
considered a routine restorative procedure, yet technique
and materials vary considerably for endodontic treated teeth with minimal tooth structure loss conservative approach should be considered first. For endodontically treated teeth with extensive structural loss caused by decay , trauma or previous restorations; post core build up is indicated. Different types of post core materials and techniques are presently available. The dentist might base his selection on the mode of fabrication namely cast versus direct. Although the cast gold post and core is considered the gold standard by many institutions, evidence base approach for selection might not support this choice. The direct metal post is fabricated of stainless steel, brass, or titanium. The direct non-metal post is fabricated from ceramic, carbon fiber or glass-fiber. The post can be either cemented with zinc phosphate or glass-ionomer or bonded with bonding agents and resin cements. Amalgam glass ionomer and composite used as a core and build up materials. Information the clinician must take into consideration, when making selection of materials and techniques. Evidence-based approach will be used to help the dentist reach a rational approach to achieve a clinically predictable outcome. This presentation will focus on
- Basic biomechanical considerations.
- Proportional of post, buildup and bonding materials.
- The goal of achieving high levels of clinical success when restoring an endodontically treated tooth by choosing
   what fit best to individual restorative needs will be discussed.

In this study the adhesion of 4 types of root canal sealers {Endofil, a ZOE based sealer; CRSC a CaOH based sealer; Ketac-Endo, a glass ionomer based sealer and AH 26, a resin based sealer} to gutta-percha and dentin with and without smear layer were studied and compared using different methods. Shear bond strength of the root canal sealers to gutta percha was tested using an easily reproducible model. Push out method was applied to measure shear bond strength of the root canal sealers to dentin using 10 cross-section root canal specimens (2-mm in thickness) filled with each type of examined sealer. Five specimens with smear layer and five specimens without smear layer. Two longitudinal root canal sections, one with smear layer and the other without smear layer were used to study linear shrinkage of each sealer using S.E.M. Sealers flow was done according to ADA specification no 57 to give more information about its adhesive character.

Furthermore apical microleakage was evaluated in 6 single rooted teeth for each tested sealer after decapitation, root canal instrumentation (3 root canals with smear layer and 3 without smear layer) obturation, immersion in blue India ink for 3 days and clearing. The penetration of India ink in the apical region was measured in the cleared specimens under traveling microscope.

The smile is considered as the unpronounced dialogue language among people. Tooth bleaching has come as one
of the proposed solutions to give the teeth that snow-white color that adds to the beauty of the face and gives
confidence to the smiling person. A discussion of bleaching materials, their kinds, methods to be used
(external or internal) their side effect and complications will be considered.

The effect of core material and post diameter on fracture load of Endodontically treated lower first premolars. Thirty-five freshly extracted human first premolars were used in this study. The experimental groups were obturated using system-B, to permit a post space. The largest easy post drill was used to prepare the root canal to receive the post. Occluso-mesial cavities were prepared in the two experimental groups. Teeth preparations were done under 4-X magnification using the surgical microscope. One experimental group was restored with light cured composite and the other was restored with chemically cured composite. The two experimental groups were subdivided into three equal subgroups, five each. The subgroups had the smallest easy post size, the largest easy post size, and without post respectively. Teeth were subjected to fracture load test. The results of this study showed increase in fracture load of teeth restored without post. Sound teeth showed the highest load fracture. Teeth restored with the largest post and chemical cured composite showed the least load fracture.

There is currently a swing of the endodontic pendulum back to reconsideration of laser application in our small world. Because laser is simply a beam of light , but has been amplified by a particular process of stimulated emission of radiation; it has acquired unique properties quali8fying it to join many endodontic aspects, starting with diagnosis through different steps of conventional and surgical root canal therapy. A brief review of different types of lasers with special reference to the most recent will be highlighted, together with offering information to help clinicians get the most of this tool while avoiding its hazards.
