Evaluation of apically extruded debris associated with several Ni–Ti systems

Üstün Y, Çanakçi BC, Dinçer AN, Er O, Düzgün S. Evaluation of apically extruded debris associated with several Ni–Ti systems. International Endodontic Journal.

Abstract

Aim

To evaluate the apical extrusion of debris associated with several root canal preparation systems in vitro.

Methodology

Forty-five extracted human mandibular premolars with single canals and similar lengths were used. The root canals were instrumented using ProTaper Next (Dentsply Maillefer, Ballaigues, Switzerland), Twisted File (SybronEndo, Orange, CA, USA) or WaveOne (VDW GmbH, Munich Germany). Debris extruded apically during instrumentation was collected into pre-weighed Eppendorf tubes. The Eppendorf tubes were then stored in an incubator at 70 °C for 5 days. The Eppendorf tubes were weighed to obtain the final weight of the Eppendorf tubes plus extruded debris. Three consecutive weights were obtained for each tube. The groups were compared using the Kruskal–Wallis one-way analysis of variance on Ranks and Tukey's test.

Results

The ProTaper Next group produced the highest mean extrusion value whilst WaveOne produced less debris compared with all the other instruments (> 0.05). There was a significant difference between the ProTaper Next and WaveOne group (< 0.05).

Conclusions

Apically extruded debris was associated with all instrumentation techniques. The WaveOne system extruded less debris compared with the Twisted File and ProTaper Next.

Nobel Biocare to Join Danaher Dental Platform


World leader in innovative implant-based dental restorations will be a cornerstone of Danaher’s global dental business

CHARLOTTE, N.C. — (September 15, 2014) Danaher Corporation announced today that it has entered into a definitive transaction agreement to acquire Nobel Biocare Holding AG, the world leader in implant dentistry. Over the past 40 years, Nobel Biocare has established itself as a pioneer in nearly every aspect of implant dentistry — from PI Brânemark’s discovery of osseointegration, to Procera digital prosthetic solutions and treating fully edentulous patients. In doing so, Nobel Biocare has dramatically changed the lives of millions of patients. Implants and prosthetics are one of the most exciting categories in dentistry today, offering a unique opportunity for dental professionals to deliver long-term solutions to women and men who desire a smile that is both beautiful and functional. With the ways in which technology and materials science continue to shape the implant dentistry workflow, bringing Nobel Biocare to the dental platform upholds Danaher’s commitment to be a world leader in dentistry.
Nobel Biocare will be a cornerstone of the dental platform. With the addition of Nobel Biocare, Danaher will be the strongest consumable and equipment player in the dental industry, with sales approaching $3 billion. Dental implants is a $3.5 billion market with attractive long term growth drivers, including an aging population, growing income in high growth markets and low penetration rates of dental implants in most geographies today. With this acquisition, Danaher will have an unmatched position in dental implants with Nobel Biocare in the premium segment and the Implant Direct joint venture in the value segment; the company plans to further invest in both these segments. Nobel Biocare will operate as a stand-alone company within Danaher’s dental platform, maintaining its own brand and identity. Implant Direct will remain as a stand- alone joint venture with no change in its go to market strategy.
“We will continue to invest in a wide range of dental technologies and innovations to better serve our customers. Bringing Nobel Biocare’s deep expertise in implant dentistry, digital prosthetics and software solutions together with our extensive knowledge in 3D imaging, intraoral scanning and digital restorative solutions will further enable us to optimize and integrate workflows. This will lead to better clinical outcomes, shorter treatment times and fewer office visits to the benefit of patients and dental practitioners,” said Henk van Duijnhoven, Senior Vice President of Danaher’s dental platform. “This combination will further support our business strategy and position our dental business for future growth.”
Danaher’s dental platform reaches 99% of all dental practices through an extensive network of dealer partners as well as direct sales. It will continue its strategy of working closely with its highly valued distribution partners as well as direct sales to maximize market access for all its brands.
“Nobel Biocare’s leadership team has done an outstanding job creating a strong platform for future growth over the last couple of years,” van Duijnhoven added. “Our team is excited to work with CEO Richard Laube and the Nobel Biocare team to build on their efforts toward
continued innovation, growth and business improvement. We look forward to welcoming all Nobel Biocare’s associates, customers and key opinion leaders to the Danaher team.”

Carestream Dental Launches New ‘TechCheck’ Promotion to Diagnose Outdated Equipment and Offers Treatment Plans for Practices


ATLANTA—Sometimes, even dental practices need to be diagnosed—for broken or outdated technology, that is. Starting now through early December, Carestream Dental’s new TechCheck promotion gives practices the chance to trade in or upgrade their existing equipment, ensuring that doctors are treating their patients with the most up-to-date technology available.
The TechCheck, which runs until Dec. 19, includes a free consultation to identify opportunities for technological improvements, such as switching from desktop-based to cloud-hosted practice management software or updating from 2D to 3D imaging. Practices will then have the option to upgrade or trade in their current technology for the latest offerings from Carestream Dental, including special savings of up to $25,000.
“When equipment is up-to-date, practices can improve patient diagnosis, optimize workflow, ensure they are HIPAA-compliant, and improve technology integration options,” David Roudergues, director of U.S. dental equipment, Carestream Dental, said. “The TechCheck lets doctors take care of their patients, while Carestream Dental takes care of their technology.”
More importantly, doctors would be well advised to understand the implications of using older models that are compatible only with Windows XP, as they are more susceptible to security breaches and HIPAA violations that could require disclosure to all patients. Working with the most recent equipment, or at least equipment that can be easily updated, is also important when it comes to HIPAA-compliance. Practices should be aware of whether their office complies with the latest requirements as well as if systems can be updated or if replacements are necessary.
“Even patients can tell you how quickly technology changes these days—just think of their smartphones—and dental technology is no different,” Roudergues said. “A perfect example is the transition from 2D to 3D imaging and, more recently, the move to digital impressions. These advances took place just within the last 10 years; it can be exhausting to keep up with it all. A TechCheck consultation removes the guesswork and helps a practice determine whether there are better, more current equipment options available to them.”
Some of the technology that Carestream Dental will be evaluating includes extraoral imaging systems, CAD/CAM systems, intraoral sensors and practice management software, to name just a few.
Carestream Dental also provides resources such as checklists and self-assessments for   knowing when to upgrade on its blog, the Digital Image Stream, at www.carestreamdentalblog.com.

Bacterial Removal Promoted by 2 Single-file Systems: Wave One and One Shape

Journal of Endodontics

Abstract

Introduction

Different single-file systems are available for endodontic treatment; however, comparative studies are scarce. Thus, the present study evaluated bacterial reduction promoted by 2 single-file systems: Wave One (Dentsply Maillefer, Ballaigues, Switzerland) and One Shape (Micromega, Besancon, France).

Methods

Forty-five distobuccal root canals of upper molars sterilized with ethylene oxide were infected with Enterococcus faecalis for 21 days, and then root canal initial bacterial sample was collected with paper cones and plated on M-enterococcus agar. The specimens were randomly divided into 3 groups according to instrumentation (n = 15): Wave One, One Shape, and the crown-down manual technique (control group). The other 6 specimens without contamination were control asepsis. After instrumentation, samples were collected with the use of scraping and paper cones. The bacterial reduction was calculated, and then intragroup analysis was performed using the paired t test and intergroup analysis using analysis of variance (both at 5% significance).

Results

All techniques significantly reduced the number of bacteria in the root canal (P < .05), with no significant difference between them (P > .05). The aseptic control group did not show any bacterial growth.

Conclusions

It can be concluded that the single-file systems Wave One and One Shape significantly reduce the bacterial number in the root canal and that there is no significant difference in their bacterial reduction abilities.

Immediate loading in partially and completely edentulous jaws: a review of the literature with clinical guidelines

De Bruyn, H., Raes, S., Östman, P.-O. and Cosyn, J. (2014), Immediate loading in partially and completely edentulous jaws: a review of the literature with clinical guidelines. Periodontology 2000, 66: 153–187. doi: 10.1111/prd.12040

Abstract

The introduction of immediate loading was a paradigm shift in implant dentistry as it was previously believed that an unloaded period was essential for bone healing in order to promote osseointegration. However, this belief could not be confirmed by clinical studies or by human histology. Hitherto, numerous reports have been published on immediate loading in various indications. An important factor for success is primary implant stability. The latter can be improved by adapting drilling protocols to enhance lateral compression of the bone and by using tapered implant designs with apical thread fixation. To some extent, the use of implants with a microrough surface and rigid splinting may compensate for suboptimal stability. It is important to avoid fracture of the provisional restoration at all times as this may result in local overloading and implant failure. Also, unevenly distributed occlusal contacts may contribute to failure and therefore occlusion ought to be evaluated at every occasion, especially during the early phase of healing. Taking these aspects into account, immediate loading in the fully edentulous mandible by means of an overdenture has been shown to be predictable in terms of implant survival (94.4–100%). However, the procedure may result in additional costs as a result of the need for repeated relining. In addition, the scientific basis for this treatment concept in the maxilla is very scarce. Immediate loading in the fully edentulous jaw by means of a fixed prosthesis is a well-documented treatment concept. In the mandible, three implants have been shown to be insufficient, given the failure rate of up to 10%. With at least four implants a failure rate of 0–3.3% may be expected. In the maxilla, four to six implants could be too limited, given the failure rate up to 7.2%. Increasing the number of implants may reduce implant failure to 3.3%. Provisional fixed prostheses are particularly prone to fracture in the maxilla and hence reinforcement is warranted. Immediately loaded single implants have lower survival rates, of 85.7–100%, with no clear impact of occlusal contact. In fact, a meta-analysis demonstrated a five times higher risk of failure for immediately loaded single implants when compared with delayed loading. No study showed superior soft-tissue preservation or esthetics following immediate loading of single implants compared with other loading protocols. However, this finding may not imply that a provisional implant crown becomes redundant when soft-tissue conditioning is deemed necessary. Taking into account earlier factors for success, immediate loading in the partially edentulous jaw by means of a fixed prosthesis seems predictable in terms of implant survival (95.5–100%). However, there are no studies with data on soft-tissue parameters, esthetic aspects or patient-centered outcomes, and the available studies mainly relate to the load-carrying part of the dentition. Clinical studies focusing on these aspects of treatment outcome are clearly needed. High patient satisfaction is the most important advantage of immediate loading, especially during the early healing phase. In this context, one should also realize that studies have revealed comparable patient satisfaction in patients following delayed loading once their prosthesis is in place. In the decision-making process, this aspect should be properly discussed with the patient along with other advantages and disadvantages of immediate loading.
