Abstract: This study histologically compared the in vivo debridement efficacy of a hand and rotary preparation followed by passive ultrasonic irrigation using a continuous flow of 3% sodium hypochlorite (NaOCl) versus a hand/rotary/ultrasound technique using 6% NaOCl in mesial root canals of vital human mandibular molars. Group 1 consisted of 15 teeth prepared with a hand/rotary technique followed by 1 min of ultrasonic irrigation, per canal, utilizing an ultrasonic needle in a MiniEndo[TM] unit expressing 15 mL of 3.0% NaOCl per canal. This was compared to Group 2 which was an existing sample collected and evaluated as part of a previous study. Group 2 consisted of 16 teeth prepared with the same hand/rotary/ultrasonic irrigation technique using 6.0% sodium hypochlorite. Following extraction and histologic preparation 5 um cross-sections from the 1- to 3 mm apical levels were evaluated for percentage of tissue removal from canals and isthmuses using a Neurolucida Image Analysis Program version 7.0. In Group 1, 15 out of the 16 teeth were determined to be severely curved which was significantly more than Group 2. Nonparametric testing between samples from severely curved canals revealed no statistically significant differences between Groups 1 and 2 in mean percent canal and isthmus cleanliness values. Sample values at the 1-, 2-, and 3 mm levels for the 3% NaOCl and 6% NaOCl techniques, respectively, were: canal, 81.8% versus 99.3%, 91.1% versus 100%, and 98.6% versus 96.9%; isthmus, 6.4% versus 92.9%, 19.5% versus 89.2%, and 27.8% versus 98.9%. In conclusion, hand/rotary instrumentation followed by passive ultrasonic irrigation using 6% NaOCl was not significantly different from corresponding values observed using 3% NaOCl.

Book Description
Ingle’s Endodontics, 7th edition, is the most recent revision of the text that has been known as the “Bible of Endodontics” for half a century. The new edition, published in two volumes, continues the tradition of including the expertise of international leaders in the field. Eighty-six authors contributed cutting-edge knowledge and updates on topics that have formed the core of this book for years. New chapters reflect the ways in which the field of endodontics has evolved over the 50 years since the pioneer John I. Ingle authored Endodontics. Ingle’s Endodontics will continue to be the standard against which all other endodontic texts will be measured. The 40 chapters are arranged in two volumes under three sections: The Science of Endodontics; The Practice of Endodontics: Diagnosis, Clinical Decision Making, Management, Prognosis; and Interdisciplinary Endodontics. With contributions from the world’s experts in all phases of the specialty, Ingle’s Endodontics, 7th edition promises to be an indispensable dentistry textbook, an essential part of every endodontist’s library.

Book Description
This book reviews the available information on bacterial disinfection in endodontics, with emphasis on the chemical treatment of root canals based on current understanding of the process of irrigation. It describes recent advances in knowledge of the chemistry associated with irrigants and delivery systems, which is of vital importance given that chemical intervention is now considered one of the most important measures in eliminating planktonic microbes and biofilms from the infected tooth. Recommendations are made regarding concentrations, exposure times and optimal sequences. Possible complications related to the use of the different solutions are highlighted, with guidance on response. In addition, clinical protocols are suggested on the basis of both clinical experience and the results of past and ongoing research. Throughout, a practical, clinically oriented approach is adopted that will assist the practitioner in ensuring successful endodontic treatment.

Book Description
The purpose of this study was to evaluate and compare the debridement efficacy of the EndoActivator (Dentsply Tulsa Dental, Tulsa, OK) versus the Ultrasonic Bypass system (Vista Dental) following hand-rotary instrumentation in anterior teeth. Sixty extracted human, maxillary anterior teeth were randomly assigned to three groups. Teeth were instrumented using (ISO k-flex) hand files and EndoSequence nickel-titanium rotary files (Brasseler, Savannah, GA) to a size 40/.06 taper. Group 1 served as the control group and had no additional treatment performed. Groups 2 and 3 were subjected to a final irrigating regimen that consisted of 6-percent sodium hypochlorite for a 1- minute duration. For group 2 the irrigation solution was activated for 1 minute using the EndoActivator system (DENTSPLY). For group 3, the irrigation solution was activated for 1 minute using the Ultrasonic Bypass System (Vista Dental). The teeth were then sectioned longitudinally and each half was divided into three equal parts 3 mm from the anatomic apex. The sample with the most visibly identifiable section of the apex was used for SEM evaluation. A scoring system to measure the efficacy of debris removal was utilized to quantify the results. Statistical analysis was performed using the Kruskal- Wallis test. If the overall test is significant, a Wilcoxon Rank Sum tests was used to compare each pair of groups. The results of this study indicate that both the EndoActivator and Ultrasonic Bypass groups had a smaller percentage of canal space occupied by smear layer and debris when compared with the control group at all three levels. This difference was statistically significant for the Ultrasonic Bypass System when compared with the control at both the coronal and middle thirds of the samples evaluated. This difference was not statistically significant in the apical third. When compared with the EndoActivator, the Ultrasonic Bypass System produced cleaner canals in the coronal and middle thirds, with the difference being statistically significant in the middle third only. These results of this research support the use of either of these two devices when compared with the controls. Smear layer removal and debridement efficacy was greatly increased when using either sonic or ultrasonic activation of sodium hypochlorite. More research is warranted concerning these two devices. Examining the antimicrobial efficacy with the use of these two devices could lend additional validation to their use in non-surgical endodontic therapy.

Book Description
Clean root canal systems are essential for successful endodontic treatment. With contributions from leading endodontists from around the world, Dr. Nestor Cohenca here presents the etiology of endodontic disease caused by the endodontic biofilm and all therapies available to predictably disinfect the root canal system, thus increasing successful endodontic outcomes. Disinfection of Root Canal Systems: The Treatment of Apical Periodontitis is an evidence-based manual that describes root canal anatomy, the endodontic biofilm, and the role of disinfection before presenting the most up-to-date methods of irrigation and disinfection. Individual chapters are devoted to each method, such as positive pressure irrigation, apical negative pressure irrigation, sonic activation, photodynamic therapy, laser technology, and ozonization and electrochemical activation. Clinical photographs throughout show proper irrigation and disinfection techniques.
