3D obturation of the root canal is a common desired goal of all methods of root canal treatment. In narrow and round canals this goal can easily be achieved. Nevertheless, oval canals present a challenge that requires some additional considerations. Cleaning and shaping of such oval canals represent the first challenge, as debris remaining in or packed into un-instrumented recesses may prevent adequate 3D adaptation of the root filling to the canal walls. Various methods that are designed to allow effective cleaning of these areas and problems and solutions to achieve good 3D obturation of oval canals will be discussed.

The introduction of NiTi alloy for hand filing and later the launch of engine driven instruments have significantly altered the canal shaping procedure over past two decades. Several studies have concluded that none of the instrumentation techniques or devices currently used can completely clean root canals, especially curved roots. The thickness of the remaining dentine following intraradicular procedures may be the most important iatrogenic factor that correlates to incoming fracture resistance of the root. Excessive flare of coronal third is not necessary, since flaring could considerably reduce the residual dentin leading to greater susceptibility to vertical root fractures. Moreover, preparation of the apical third can also reduce residual dentin resulting in weakened apical root structure. This is particularly important in a root with an oval cross section. On the other hand, there are other studies that report dentin removal may not necessarily increase the risk of fracture and that there was no significant difference in fracture load between teeth prepared by SS hand instruments or those prepared by Ni-Ti rotary instruments. Regardless of the instrumentation technique, cleaning and shaping procedures invariably lead to dentine removal from the canal walls. Residual dentin thickness of all multitapered rotary and reciprocating instruments and single file rotary instruments show that they remove less dentin as compared to hand instruments.

The primary objective of the pulp therapy is to maintain the integrity and health of damaged teeth and there supporting tissues. Direct pulp capping involves the application of a medicament, dressing or dental materials to the exposed pulp in an attempt to preserve the vitality. The rationale behind this treatment is to encourage the pulp to initiate the reparative dentin formation at the exposure site. Many materials have been advocated as pulp capping agents. Calcium hydroxide is being accepted as gold standard. A number of newer materials have been advocated as alternative to calcium hydroxide that includes MTA, Geristore, Propolis, Biodentine, Emdogain and Dentin Bonding Agents. These materials overcome the potential disadvantages associated with the calcium hydroxide such as its high solubility, subject to dissolution over time, no inherent adhesive qualities and poor seal. The aim of this poster is to give an insight of these newer materials.

Nickel-titanium (NiTi) rotary instruments are commonly used for endodontic practice to improve root canal preparations. These instruments offer many advantages as they are more flexible and have increased cutting efficiency and superelasticity of these instruments allows the clinicians to produce the desirable tapered root canal form with a reduced tendency to canal transportation. In clinical practice these instruments are associated with an increased risk of fracture, mainly because of failure by fatigue and torsional shear stresses. Recently, NiTi instruments were introduced that advocated the concepts of reciprocation. These are manufactured with M-Wire NiTi alloy. The manufacturer’s claim that the reciprocal motion decreases the impact of cyclic fatigue, reduce the torsional stress by periodically reversing the rotation and increasing the life span of the instrument thus exhibiting superior mechanical properties. They claim to shape the root canal with only one file thus saving time. Thus, it seems that the reciprocatory motion appears to be advantageous as compared to the rotary instrumentation.

A newly developed self-adjusting file (SAF) was designed to address the shortcomings of traditional rotary files by adjusting itself to the canal cross section. This instrument consists of a compressible opened NiTi tube that, on placement into a root canal, will exert pressure against the canal wall. The SAF is used in an in-and-out motion powered by a handpiece and under constant irrigation. Self-Adjusting file (Re-Dent-Nova, Ra’anana, Israel) which hollow file designed is a novel system among the nickel-titanium files operating in a different manner. It adapts itself to the canal’s original anatomy and shape, longitudinally to a curved canal, as will all rotary nickel-titanium files, especially differently adapts itself to the cross-section of the canal, providing three-dimensional adaptation during the cleaning and shaping process. The SAF represents a new approach in endodontic rotary file design and operation.

Regenerative endodontic procedures can be defined as biologically based procedures designed to replace damaged structures, including dentin and root structures, as well as cells of the pulp-dentin complex. The objectives of regenerative endodontic procedures are to regenerate pulp-like tissue, ideally, the pulp-dentin complex; regenerate damaged coronal dentin, such as following a carious exposure; and regenerate resorbed root, cervical or apical dentin. Regenerative techniques has advantages and disadvantages, and some of the techniques are hypothetical, or at an early stage of development. The proposed therapies involving stem cells, growth factors, and tissue engineering all require pulp revascularization, in itself an enormous challenge. One of the most challenging aspects of developing a regenerative endodontic therapy is to understand how the various component procedures can be optimized and integrated to produce the outcome of a regenerated pulp-dentin complex. The future development of regenerative endodontic procedures will require a comprehensive research program directed at each of these components and their application.
