The dental profession’s most important goal is to maintain the health and integrity of patient's dentition. Dental clinicians must recognize that a particular method of obturation can not satisfy every single case that requires endodontic therapy. This book is an attempt to shed light on various available techniques and materials of obturation which are consistent with the principles of clinical practice, i.e., to provide the best treatment for patients.
This study was done to compare and evaluate the quality of obturation in simulated internal resorptive cavities using different gutta percha obturation techniques and also to compare radiographic and stereomicroscopic methods used to evaluate the quality of obturation. Thirty extracted maxillary central incisors were instrumented at the working length to a #50 file. The roots were sectioned transversely with a diamond disc at 7 mm from the anatomical apex. At the opening of the root canal of each section, hemicircular cavities were drilled with a round bur #5 with a stopper. The corresponding root sections were cemented with glue, thus obtaining root canals with similar cavities that simulated internal resorptions. The specimens were randomly separated into three groups of 10 each. The following obturation techniques were evaluated Group A : Hybrid technique (Combination of lateral and vertical compaction) Group B : Ultrasonic compaction (Satellac). Group C : Thermo plasticized gutta percha (Ultrafil) The teeth were then examined radiographically and stereomicroscopically.
In the past era of dentistry, it was believed that, “It Is What Is Removed From the Canal That Is Important, Not What Is Put In”. But with the evolution of endodontics & a better understanding of the root canal system, researchers have attributed failure of root canal therapy largely to incomplete obturation of the root canal system. Although the clinician has a variety of obturation techniques to choose from today, the quality of seal produced by either of them is questionable. One of the biggest challenges that faces endodontics in this millennium is to find a material that can form a leakproof seal that is bioinductive and promotes regeneration, or a "smart" material that can adapt to the ever-changing microenvironment of the canal system. This book is a compilation of the golden standards of obturating materials, types of root canal sealers, root canal filling techniques & the more current clinical data that are based on procedures performed with more advanced techniques. With the knowledge of these recent innovations, the future holds the promise of providing the most valuable thread of evidence connecting the patient & the clinician in delivering the oral health care.
Obturation of the root canal system is an integral component in promoting periapical healing and preventing disease progression. The root canal filling material accomplishes this by reducing microleakage and entombing any inflammatory irritants. The effectiveness of a material to adequately seal the root canal space is established by its physical properties and handling characteristics. The gamut of materials run from tin, gold foil, cotton pellets, with various medicaments of wood, plaster, oxyphosphate of zinc, zinc oxide, paraffin, copper points, various metals, amalgam, silver cones, to the most popular, gutta-percha. Over the past century, numerous obturation materials and delivery techniques have been introduced in an attempt to obtain a microbiologic barrier within the confines of the root canal system. Different materials have their limitations and advantages. Thus numerous techniques have been proposed, experimented with and implemented to achieve the most dense obturations.
It is time to evolve over conventional techniques and rise to the next level of advanced root canal treatment. This Book justifies innovative, economical & efficient use of Heat + Sonic Vibration Technology for Obturation and the comparison of the same with other obturation techniques.One of the purposes of root canal treatment is to fill the root canal system in order to prevent re-infection. Obturation is the culmination of the endodontic triad. It marks the end point of the endodontic treatment sequence. But it is also the harbinger of holistic healing of peri-apical tissues. A hermetic seal initiates and encourages repair and regeneration. Hence 3-dimensional obturation of the canal space is provision of fluid tight seal with an inert, biocompatible material is the ultimate goal of endodontic therapy.
This book contains the fundamental details and clinical tips for a successful obturation in order to achieve a " fluid tight seal". moreover the "e&q master" from meta-biomed is used for thermoplastic obturation and the latest "guttaflow-2" from coltene is used as a cold flowable gutta-percha system. they are compared with conventional lateral condensation obturation technique.

Although root canal treatment is a highly successful entity, 60% of endodontic failure occurs due to improper obturation. This statistic delineates the difficulty and complexity that the good obturation entails. The demanding nature of this vital steep has spawned not only numerous materials but also myriad techniques to achieve that ideal obturation. A thorough knowledge of all the Techniques is a must. This books is a one stop solution for problems regarding the numerous Rot Canal Obturation Procedures.
Inspite of best bio-mechanical preparation and new obturation techniques being introduced, still in the present conditions and circumstances, no one obturation technique can fulfill all the requirements for an ideal obturation that can be used easily and mastered to treat all of the endodontic cases. These techniques have to be mastered and practiced before they are put into clinical practice. The new equipment and devices can render excellent results if mastered but can lead to serious consequences if used by unskilled clinicians. The transition is slow, but exciting, so clinician should understand the patient’s need and indication for particular technique and material used for the obturation of root canal space. So this book basically aims at reviewing and highlighting the obturation devices used during root canal treatment of teeth so to make the treatment more easy for patient and clinician as well and achieving high success rate.
The root canal system has many variations in anatomy such as irregularly shaped canals, lateral and accessory canals, and a variety of fins which lead to difficulty in preparing the canals to form conducive to complete obturation with filling materials whenever a need for endodontic therapy arises. The final goal of endodontic treatment is to fill the entire root canal system and all its complex anatomic pathways completely and closely with non irritating hermetic sealing agents.The achievement of a “Hermetic seal” is often cited as the major goal of root canal treatment. As guttapercha is a benchmark for root canal obturation an attempt has been made in the form of a book to review the current dental literature of guttapercha and to discuss its forms, properties, its advantages along with its different techniques used for obturation of guttapercha.
A major cause of coronal tooth discoloration may be attributed to remnants of obturation materials left in the pulp chamber following root canal therapy. Endodontic materials that contain certain compounds such as eugenol, phenol, and silver additives may lead to colour changes in coronal tooth structure when they come in contact with dentine. The degree of staining in such cases varies according to the material used and is usually challenging to manage. Several studies evaluated the discoloration potential of sealers and the changes over a period of time. Most of the previous studies used digital imaging as a method of colour measurement, and focused on limited products only.The objective of this study was to assess coronal discoloration due to four commonly used endodontic sealers with gutta- percha, using spectrophotometric analysis.
The endodontic triad; consisting of biomechanical preparation, microbial control and complete obturation of the canal space; remains the basis of endodontic therapy. Complete obturation of pulp space as efficiently and three dimensionally as possible is considered to be an important part of root canal treatment. Endodontic literature reports the need to seal the root canal in a hermetic way i.e. the canal system should be sealed apically, coronally and laterally. Leonardo and Leal (1991) affirmed that to seal a root canal means to fill it in all its extension with an inert, antiseptic material, obtaining the most hermetic seal possible. Various endodontic materials have been advocated for obturation of the radicular space. Most techniques employ a core material and a sealer. All core materials require a sealer. There are no exceptions to this rule. Although there are a large number of filling materials, the combination of gutta-percha and a sealer is most widely used in clinical practice. The purpose of sealing root canals is to prevent periapical exudates from diffusing into the unfilled part of the canal, to prevent re-entry and colonization of bacteria .
