This book was released on 2009 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2005 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

This book was released on 2006 with total page 656 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The use of ultrasound as an adjunct to conventional instrumentation procedures has been suggested to enhance the removal of a bacterial biofilm and necrotic debris from necrotic root canals. The purpose of this in vivo, prospective, randomized, single-blind study was to histologically compare the efficacy of hand and rotary instrumentation versus hand and rotary instrumentation plus 1 minute of ultrasonic irrigation using an ultrasonic irrigating needle connected to a MiniEndo[TM]piezoelectric ultrasonic system in the mesial roots of necrotic, human mandibular molars to remove the bacterial biofilmlnecrotic debris. Group 1 consisted of 20 teeth prepared with a handlrotary technique while Group 2 consisted of 20 teeth prepared with the same handlrotary technique followed by 1 mm of ultrasonic irrigation, per canal, utilizing an ultrasonic needle in a MiniEndoTM unit and an additional 15 mL/canal of 6.0% sodium hypochlorite. Eight uninstrumented, necrotic mandibular molars served as histological controls. Following extraction and histological preparation, 0.2 um cross-sections from the 1.0- to 3.0 mm apical levels were evaluated for the percentage of remaining bacterial bioflim/necrotic debris in canals using a Neurolucida Image Analysis Program version 5.0. Nonparametric testing revealed mean percent canal and isthmus cleanliness values to be significantly higher for Group 2 at all levels evaluated. Sample values at the 1.0-, 2.0-, and 3.0 mm levels for the handlrotary and handlrotary/ultrasound techniques, respectively, were: canal, 80.1% versus 94.7%, 91.6% versus 99.0%, and 95.1% versus 99.6%; isthmus, 33.3% versus 82.8%, 3 1.4% versus 86.1%, and 44.6% versus 91.1%. In conclusion, the 1 minute use of ultrasonic irrigation following handlrotary instrumentation resulted in significantly cleaner canals and isthmuses in the mesial roots of necrotic, mandibular molars.

This book was released on 2010 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Pafford and published by . This book was released on 2007 with total page 694 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The use of ultrasound as an adjunct to conventional endodontic cleaning and shaping procedures has been shown to enhance the removal of pulp tissue, bacteria, and necrotic debris from inflamed and infected root canals. However, no study to date has evaluated the operative and postoperative pain of ultrasound use. Therefore, the purpose of this in vivo, prospective, randomized, single-blinded study was to compare the operative and postoperative pain of a hand and rotary instrumentation technique versus a hand and rotary instrumentation plus 1 minute ultrasound technique using an ultrasonic irrigating needle connected to a MiniEndo[TM] piezoelectric ultrasonic system in the root canals of vital and necrotic teeth. Forty-nine subjects completed this study. Teeth in Group 1 were prepared with a hand and rotary instrumentation technique followed by 1 minute of mock ultrasonic treatment. Teeth in Group 2 were prepared in a similar fashion but followed by 1 minute of ultrasonic irrigation with 6.0% sodium hypochlorite per canal. The groups were subdivided and analyzed by diagnosis. Group 1[ip] consisted of 19 subjects with a diagnosis of irreversible pulpitis, and Group 2[ip] consisted of 13 subjects with a diagnosis of irreversible pulpitis. Group 1[np] consisted of 7 subjects with a diagnosis of necrotic pulp, and Group 2[np] consisted of 10 subjects with a diagnosis of necrotic pulp. The groups diagnosed with irreversible pulpitis groups and with necrotic pulp were similar with regard to gender, preoperative pain, and age. The subjects completed an intraoperative pain survey and a 3-day postoperative pain survey. All subjects were given ibuprofen 600 mg and Tylenol #3 for pain management and recorded consumption of the medications. All groups had mean intraoperative pain scores considered to be mild pain and ranged from 0 to 23 mm on a 170 mm visual analogue scale. No subject reported symptoms of a sodium hypochlorite accident (immediate pain or swelling). Postoperative pain and postoperative percussion pain showed a general trend of decreasing pain over time for subjects with a diagnosis of irreversible pulpitis. Group 2[ip] females had significantly more postoperative pain than Group 1[ip] females on the day after treatment. Group 1[ip] males had significantly more postoperative percussion pain at time period 1 than Group 2[ip] males. Females with irreversible pulpitis required significantly more ibuprofen, but not more Tylenol #3, than males with irreversible pulpitis. There were no significant differences in postoperative pain for either gender at any time for the necrotic pulp groups. Postoperative pain, postoperative percussion pain, and medication consumption did not vary significantly with time in the necrotic pulp groups. The results of this study indicate the addition of 1 minute of ultrasonic irrigation after hand and rotary instrumentation is a safe procedure and relatively pain free when used in the root canals of vital and necrotic teeth. The addition of ultrasonic irrigation to the root canal cleaning and shaping protocol has minimal effects on intraoperative pain, postoperative pain, postoperative percussion pain, and post-treatment medication consumption.

Download or read book An In vitro SEM Study Comparing the Debridement Efficacy of the EndoVac System Versus the Canal CleanMax Following Hand rotary Instrumentation written by Benjamin Paul Ricketts and published by . This book was released on 2010 with total page 656 pages. Available in PDF, EPUB and Kindle. Book excerpt: 3 This in-vitro, prospective, randomized study microscopically compared the debridement efficacy of negative pressure irrigation with the EndoVac (Discus Dental, Culver City, CA) versus the Canal CleanMax (Maximum Dental, Inc., Secaucus, NJ). Sixty extracted human canines were instrumented using a combination of hand-instrumentation with Lexicon K-type files and rotary instrumentation with ProTaper files. All canals were irrigated with 6.0-percent sodium hypochlorite and 17- percent ethylenediaminetetraacetic acid (EDTA). However, the irrigation/aspiration techniques differed among three groups of 20 randomly selected teeth. Group one (control) was irrigated with only a 12-ml Monoject syringe via 30-gauge side-vented, closed-end 328 needle. Group two was irrigated with the EndoVac system. Group three was irrigated similar to group one, but with the adjunct of the Canal CleanMax system. All teeth were sectioned longitudinally, and the more intact sections were divided into coronal, middle, and apical thirds. Each portion of the canal was photographed with a scanning electron microscope (SEM). The photographs were scored by two independent examiners according to relative amount of debris and/or smear layer present, as well as relative number of patent dentinal tubules. These scores were statistically analyzed using a Krustal-Wallis test and Wilcoxon Rank Sum tests to determine differences between groups. The coronal aspect of root canal walls irrigated with the EndoVac system exhibited significantly less debris and/or smear layer present when compared to the coronal aspect of root canals irrigated with only a standard 12-ml Monoject syringe equipped with 30-gauge ProRinse side-vented, closed-end needle (control). There were no other significant differences in scores between any groups at any location. For all locations combined, the EndoVac system produced significantly cleaner root canal walls as compared to the control. No significant differences were seen between the Canal CleanMax and Control or Canal CleanMax and EndoVac. This study suggested negative pressure irrigation delivery with the EndoVac system during and after hand-rotary instrumentation is more effective in removal of debris and smear layer from the coronal third and combined thirds of root canal walls compared to irrigation with a standard 12-ml Monoject syringe equipped with 30-gauge ProRinse side-vented, closed-end needle.
