Book Description
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
The use of ultrasound as an adjunct to conventional instrumentation procedures has been suggested to enhance the removal of bacteria and necrotic debris from infected root canals. The purpose of this in vivo, prospective, randomized, blinded study was to compare the antibacterial efficacy, by means of microbial culture methods and the specific ability to eliminate E. faecalis as measured by polymerase chain reaction (PCR), of a hand and rotary instrumentation technique versus a hand and rotary instrumentation plus one-minute ultrasound technique using an ultrasonic irrigating needle connected to a MiniEndo(TM) piezoelectric ultrasonic system in the mesial roots of infected, necrotic, human mandibular molars. Thirty-three subjects participated in this study. Group 1 consisted of 17 mesial roots prepared with a hand and rotary instrumentation technique and conventional irrigation with 6.0% sodium hypochlorite. Group 2 consisted of 16 mesial roots prepared in a similar manner followed by 1 minute of ultrasonic irrigation with 6.0% sodium hypochlorite per canal. The canals were sampled prior to treatment, after instrumentation for both groups, and after syringe irrigation for teeth in Group 1 and after ultrasonic irrigation for teeth in Group 2. The samples were incubated anaerobically for 7 days at 3 7°C, the bacteria from each sample were quantified, and the CFU counts and log10 CFU counts were used for statistical analysis. Samples displaying initial growth and growth after instrumentation or ultrasonic irrigation were submitted for PCR detection of E. faecalis. All samples were positive for initial growth. Statistical analysis using the Exact Mann-Whitney-Wilcoxon test indicated no significant differences between Group 1 and Group 2 with regard to initial (p = 0.385) or post-instrumentation (p = 0.093) CFU counts. A dependent t-test showed hand and rotary instrumentation with 6.0% sodium hypochlorite irrigation significantly (p

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.
