Using the metadata, all references in an HTML document can be embedded in the file at the point of citation so readers can jump directly to the study on PubMed, CrossRef or another site. Publishers also have the option of using digital object identifiers for references, tables, and figures for ease of access from anywhere in the HTML document.
All this richly-embedded data in HTML allows for a more interesting and cohesive end-user experience, where everything they need can be found right in the document. The dynamic HTML format also allows for easily implemented real-time updates so end-users will always have the most up-to-date files. PDFs, by contrast, are static container documents with fixed layout and content embedding.
A downloaded PDF document may be out of synch with those maintained dynamically online. These are author-specific digital identifiers that ensure unambiguous ownership of work. By harnessing all this usable information first, enriched source documents can be transformed into accessible website content, ePubs, PDFs, HTML documents, or print products.
The XML-first workflow gives you the widest range of options right from the start. For more, see Maximize publishing workflows without shocking your culture. Roots with abnormal root canal morphology. Active acute infection — cellulitis, abscess.
Proximity of vital anatomical structures to the periapical lesion. Both instruments are for single use. One end is bent and is designed to enter the periapical tissues through the root canal and apical foramen, whereas the other end has a latch-type connector to allow its operation by a low- speed contra-angle hand piece. The bent part is initially concealed in a straight super elastic Nitinol tube that serves as a sheath allowing its introduction up to the apical foramen.
When pushed, the wire emerges from its sheath and through the apical foramen and resumes its preshaped form. The special retrograde design of the bent part allows it to rotate in the periapical soft tissues at to rpm and coarsely grind them while being deflected from the surrounding bone. The Nitinol sheath is used first to allow the introduction of the Nitinol wire to the apical foramen and second to allow unobstructed rotation of the wire in the root canal without twisting of the wire.
The second device is the Apexum PGA ablator, built from a Nitinol Shaft, equipped at one end with a latch type connector to allow its operation by a low-speed contra-angle handpiece.
A 20 K-file is passed through the apical foramen and beyond the apex to verify patency. It is followed by a rotary 30 file Profile. The Apexum NiTi Ablator is then inserted, while encased in its sheath, to the working length as established at the cleaning and shaping stage.
The sheath is stabilized to the occlusal surface of the tooth using glass-ionomer cement. The Nitinol filament is then pushed manually through the enlarged apical foramen and into the periapical tissues. The filament is first rotated manually to verify mobility with no solid obstruction and then attached to a low-speed contra-angle hand piece.
The NiTi Ablator is then rotated in the periapical tissues for 30 seconds at to rpm to initially mince the tissues. The stabilizing glass-ionomer cement is then removed and the NiTi Ablator withdrawn from the root canal with its sheath to examine it for any mechanical damage or missing parts.
The root canal will be rinsed with sterile saline, and the Apexum PGA Ablator is manually inserted through the root canal and into the periapical tissues.
It was then connected to a low-speed contra-angle hand piece and rotated for 30 seconds at 5, to 7, rpm to turn the minced tissues into a thin suspension. Next, it is withdrawn from the root and examined for any mechanical damage or missing parts. The tissue suspension is now washed out with sterile saline solution by using a syringe adapted with a 30 guage blunt needle.
The needle is passed through the enlarged apical foramen into the periapical space, and Corresponding Author: The cross-sectional area between the enlarged apical foramen and the outer surface of the needle is 3.
This facilitates an unobstructed backflow and prevents pressure buildup in the periapical crypt. Nevertheless, special attention should be given to visually monitor the backflow of the blood red suspension through the root canal continuously so that pressure buildup did not occur in the periapical space. To allow for continuous monitoring, aspiration is performed at a distance from the access cavity so that the operator could visually evaluate the in-and out flow rates.
When the suspension turns pale during the process, the flushing was stopped and the needle was removed when clear solution appeared. The root canal will then be dried with sterile paper points and obturation will be done at a later date. The later traumatizes the tissue and might also introduce bacterial antigens into a tissue primed to respond to them5.
When this happens, an acute inflammatory response with resulting edema is likely to occur in the periapical tissue; thus, symptoms or flare-up might be expected14, The Apexum procedure, on the other hand, did not end with just such a trauma, allowing the above events to occur.
On the contrary, it might have removed the tissue in which such response could occur and allowed the crypt to be filled with a fresh blood clot in which the above mechanisms are not present. The extent of tissue removal and the exact nature of the processes that follow will require further verification by histologic studies.
Healing of similar lesions after apical surgery is much faster. Kvist and Reit3 have demonstrated that lesions of apical periodontitis that were treated surgically healed with kinetics significantly faster than those treated with nonsurgical retreatment, even if both groups eventually showed similar healing rates after 48 months.
Nevertheless, surgery is an invasive procedure associated with certain adverse effects 7. Therefore, it is not routinely used just to enhance the healing kinetics of periapical lesions.
According to studies, the healing of periapical lesions in the Apexum-treated group was significantly faster than in the conventional treatment group. This implies that adding the new procedure as a supplementary stage in the process of conventional root canal treatment might alter the outcome, at least as far as the healing kinetics is concerned.
Other field of dentistry that can be benefitted from this technique is Implantology: When a broken down toothwith a large periapical lesion has to be extracted and replaced by an implant, the implantologist is presented with a dilemma, if there was no bone defect around the apex, immediate implant can be successfully placed.
Of course, the implantologist would prefer to have bone at the depth of extraction socket. It is precisely such bone augmentation that the Apexum procedure provides within a relatively short time is beneficial.
