roots 01/2010

The specialist magazine roots presents the most significant international developments and experiences within the endodontic profession in an easy-to-read format to practitioners around the world. This high gloss, English language magazine is published four times a year and distributed at all major international congresses and exhibitions. roots is sent to a database of 4.000 dentists worldwide (mainly USA, Middle East & Africa, Asia Pacific, and Europe) and gets a wide bonus distribution at the following shows in 2011: IDS, SINO, FDI Mexico City and GNYDM. The content of the magazine is a combination of specialty articles, clinical studies, case reports, industry reports, reviews (meetings, products, etc.), news, and lifestyle articles. Specialists as well as general dentists are informed about new concepts in root canal treatment and the latest advances in techniques and instrumentation to help them keep pace with the rapid changes in this field.

Dr Chris J. Lampert Guest Editor Endodontist Portland, Oregon, USA
The success of modern endodontic treatment can largely be attributed to the work of Dr Herbert Schilder. This is not because he pioneered 3-D obturation with warm gutta-percha, not because he defined the first mechanical and biological objectives for shaping and cleaning a root-canal system, not because he stood by his principles in the face of criticism, but because he raised the bar for endodontic success to a new level. Numerous gifted educators and clinicians have followed and furthered Dr Schilder’s principles and techniques. In fact, in this edition of roots, two contributing authors were trained by Dr Schilder

Untying the Gordian Knot: An evidence-based endo-implant algorithm (Part I)
Dr Kenneth S. Serota, USA
Over the years, endodontics has diminished itself by enabling the presumption that it is comprised of a narrowly defined service mix; root-canal therapy purportedly begins at the apex and ends at the orifice. Nothing could be further from the truth. It is the catalyst and precursor of a multivariate continuum, potentially the foundational pillar of all phases of any rehabilitation (Figs. 1a–c)...
Apical microsurgery - Part IV: The REB and REP
Dr John J. Stropko, USA
The amount or degree of the root-end bevel (REB) is of utmost importance and should be precisely planned after considering the overall crown?root ratio, presence of posts or other obstacles, root anatomy, and periodontal status of the tooth. According to previous research, 98% of canal system ramifications occur in the apical 3mm.1 If the bevel is long (traditionally 25° to 45°), an excessive amount of root structure would have to be removed to include the apical 3mm on the palatal or lingual part of the root?s apical canal system (especially in roots with multiple canals)...
The importance of endodontics in implant treatment planning
Dr Jose M. Hoyo, USA
There’s a new vision in dentistry that is gradually being recognised and is referred to as the endo-implant algorithm. This new approach considers the role of the endodontist as critical in considering whether a tooth can be saved or whether extraction and replacement with a dental implant is the correct treatment protocol. An endodontist is in the unique position to evaluate critical factors leading to endodontic failures in order to determine whether another endodontic procedure will lead to a predictable and successful outcome. Should the outcome not be favourable, then extraction and replacement with a dental implant would be the protocol to follow...
Managing maxillary molars
Dr Mark Dreyer, USA
Maxillary first molars are notable for their complex root-canal system morphology. The mesio-buccal (MB) roots are characterised by an irregular ovoid morphology, resulting in an isthmus or fin of pulpal tissue extending palatally to the principle MB canal. This case report presents steps taken to address this anatomy in order to maximise the disinfection and debridement of the root-canal system. Failure to address this anatomic complexity may lead to persistence or recurrence of endodontic disease...
Comprehensive evaluation of previous root-canal therapy
Dr Richard E. Mounce, USA
I recently received an e-mail from a general dentist with the image of tooth #15 (Fig. 1). The e-mail read: “I have an X-ray of our son’s #15 root-canal treatment done five years ago by an endodontist. He has pain. I would like your opinion on the retreatment?” There was no additional information...
The perceptions of a David in a land of Goliaths
Dr Barry Lee Musikant, USA
When you are competing against giants in a field that has become tremendously lucrative for these giants, you could easily feel out of your depth and should beat a hasty retreat, lest you encounter their true wrath. It is undeniable that we are exposed to the all-encompassing marketing power of these giants. We recognise their ability to dominate endodontic education in the schools (both undergraduate and graduate), commercial exhibits and lectures at all the major meetings, and the majority of the articles published in trade journals, all nicely capped off with an army of salespeople who make sophisticated pitches to dentists to buy one or another of the expensive rotary NiTi systems...
Determining working length, or how to locate the apical terminus (Part 2)
Prof Vladimir Ivanovic & Dr Katarina Beljic-Ivanovic, Serbia
We would like to start the second part of our article with a quotation: “Adequate radiographs, knowledge of anatomy, and tactile sense and not apex locators will help to determine apical constriction.”2 We found this statement provocative enough to give electronic locators a chance...
File selection: Why geometry matters most
Dr L. Stephen Buchanan, USA
Shortly after the excitement of the rotary file revolution wore off, the next frontier in shaping technology became the search for faster cutting efficiency. This is logically similar to our continuing search for increasingly faster computers...
Ready-to-use root-canal sealer: 2Seal easymiX
2Seal is a tried and tested epoxy-amine-based root-canal sealer. It has been available for many years in a standard two-tube pack and is now available as 2Seal easymiX in a convenient double-chamber mixing syringe with exchangeable, flexible intra-oral tips. 2Seal easymiX always mixes to an ideal ratio, which can be applied directly into the root canal—with no mess or waste.
