Retreatment in Endodontics - From Difficult to Complicated Cases

LOD-197-00

Dr. Constantinos Laghios

In this lecture we will describe the relationship of the root canal anatomy to the lesions that are developed at the periradicular area.<BR><BR>We will also give all the details how to remove safely different kind of materials like gutta-percha, silver cones, broken instruments, posts and pastes.<BR><BR>Details will be given as to avoid any mistakes that would possibly endanger the retreatment perforations and absorptions will be treated in a fast, predictable and simple way.

Predictable and Successful Maxillary Sinus Augmentation

LOD-192-00

Dr. Toshiro Sugai

In this presentation, we will identify safer and more predictable maxillary sinus augmentation procedures. We will discuss how to utilize CT imaging to evaluate and interpret the 3D anatomy of the sinus, including ostium, superior alveolar artery, and septa. Dr. Sugai will describe how to predictably lift the sinus membrane and avoid complications.

Ridge Augmentation Using rhPDGF Growth Factors

LOD-121-00

Prof. Massimo Simion

This lecture covers the topic of ridge augmentation using the line of growthfactors termed rhPDGF (Gem-21) mixed with xenograft, TCP and autograft for implant placement. The scientific background and the first clinical cases are discussed and demonstrated. The new bone graft material shows to be an enhancement to the current technique of GBR.

The Success of Endodontic Therapy - Healing and Function

LOD-089-00

Dr. Shimon Friedman

The Success of Endodontic Therapy - Healing and Function<br>Over 30% of root-filled teeth in the population present with persistent disease, suggesting an extensive need to manage the affected teeth. Treatment options include extraction and replacement, orthograde retreatment and apical surgery, and selection between these can often be complex. When the patient is motivated to retain the affected tooth, a key consideration is the prognosis, or potential for healing; therefore, the prognosis should be communicated to patients in a clear and objective manner. This lecture focuses on the prognosis of orthograde retreatment and apical surgery.<br><br>Inconsistent reports on the prognosis of orthograde retreatment and apical surgery, in contrast with consistently favourable reports for implant-supported single-tooth replacement, have caused considerable confusion in the profession. To reliably reflect the prognosis, studies must conform to design and methodology criteria consistent with an acceptable level of evidence. These criteria are met by only a few studies on retreatment and apical surgery. This lecture identifies the studies that provide the best evidence and outlines the prognosis of retreatment and apical surgery in regards to healing and symptom-free function of the treated teeth. Furthermore, specific clinical factors are highlighted that may influence the prognosis.

Endodontic Rotary Instrumentation - How to achieve maximum efficiency while eliminating failure

LOD-085-00

Dr. John T. McSpadden

There may be more instrumentation technique recommendations than there are endodontic instruments available. Obviously, all cannot be the 'best' approach. Are these techniques confusing motion with accomplishment and time with safety? This presentation describes 6 basic principles that enable the practitioner to maximize endodontic rotary instrumentation in terms of effectiveness, efficiency and safety for any type endodontic file available today and as they become available in the future. Saving valuable time and eliminating pernicious stress are the result.

The use of MTA in Clinical and Surgical Endodontics

LOD-082-00

Dr. Arnaldo Castellucci

Recently, Dr. Mahmoud Torabinejad of Loma Linda University, California, has developed a new cement named Mineral Trioxide Aggregate which appears to have all of the characteristics requested of the ideal cement to seal pathways of communications between the pulp and the oral cavity (mechanical and carious pulp exposures), and between the root canal system and the periodontium (iatrogenic perforations, open apices, resorbed apices, root-end preparations).<br><br>MTA is an endodontic cement that is extremely biocompatible, capable of stimulating healing and osteogenesis, and is hydrophilic. MTA is a powder that consists of fine trioxides (Tricalcium oxide, Silicate oxide, Bismute oxide) and other hydrophilic particles (Tricalcium silicate, Tricalcium aluminate, responsible for the chemical and physical properties of this aggregate), which set in the presence of moisture. Hydration of the powder results in formation of a colloidal gel with a pH of 12.5, that solidifies to a hard solid structure in approximately three-four hours. This cement is different from other materials currently in use because of its biocompatibility, antibacterial properties, marginal adaptation and sealing properties, and its hydrophilic nature.<br><br>The characteristic that distinguishes MTA from other materials used to date in endodontics is its hydrophilic properties. Materials used to repair perforations, to seal the retro-preparation in surgical endodontics, to close open apices, or to protect the pulp in direct pulp capping, are inevitably in contact with blood and other tissue fluids. Moisture may be an important factor due to its potential effects on the physical properties and sealing ability of the restorative materials. As shown by Torabinejad et al., MTA is the only material that is not affected by moisture or blood contamination: the presence or absence or blood seems not to affect the sealing ability of the mineral trioxide aggregate.<br><br>During the presentation, several cases of treatment with MTA will be showed. Aim of the presentation is to show the indications and the technique for the correct use of this relatively new material: how to seal an open apex, how to repair a strip-perforation under the microscope, how to protect a pulp exposure to perform a direct pulp capping, how to use MTA during surgery to seal the retroprep.<br><br>In conclusion, the viewers should be able to appreciate the advantages of this material, which made our treatments more predictable and gave us the possibility to save teeth otherwise condemned to extraction.

Clinical Pharmacology - What Every Dentist Should Know

LOD-072-00

Dr. Anthony Feck

Modern dentistry has expanded the arsenal of services to restore patients oral health and cosmetic needs like never before. These changes have corresponded to an increasingly complex medical environment where patients are presenting at a more advanced age, with more medical conditions, and taking more medications. Understanding the pharmacology as it relates to their systems and how the drugs they are taking, as well as those we intend to administer affect the patient, one another, and our planned treatment is necessary for a safe and successful outcome to our planned care.
