Abstract For over hundred years Gutta Percha (GP) has been the most common material used for the obturation of the root canal. GP was the standard with which newer materials were tested. GP fulfills all the characteristics of an ideal root canal filling material, but has a disadvantage of not being able to seal the root canal on its own and requires a sealer for providing an effective seal. In an attempt to overcome this draw back a new root canal filling material was introduced, called, Resilon which is a thermoplastic synthetic polymer-based root canal filling material and Epiphany being the sealer. This material has the ability of forming a Monoblock with the root canal. The properties of this material has been studied, it has shown promising results and has emerged as a alternative to GP.

Besides the risk of filling material extrusion throughout the apex, a satisfactory apical seal can be difficult to achieve in canals with open apices or iatrogenic enlargements of the apical constriction. These situations pose a challenge to root canal filling. This paper describes the root canal filling of a maxillary right canine with an overinstrumented apex, complete loss of the apical stop, extensive canal transportation and apical periodontitis. A 5 mm calcium hydroxide apical plug was placed before root canal filling. The plug was made by soaking paper points with saline, dipping the points in calcium hydroxide powder and then applying it to the apex several times, until a consistent apical plug was obtained. The canal was then irrigated with saline in order to remove any residual calcium hydroxide from the root canal walls, dried with paper points and obturated with an inverted #80 gutta-percha cone and zinc oxide-eugenol based sealer by the lateral condensation technique. An 8-year radiographic follow-up showed formation of mineralized tissue sealing the apical foramen, apical remodeling and no signs of apical periodontitis.

The Mean

The objective of root canal obturation is to achieve a fluid-tight seal. Recently, GuttaFlow bioseal (GB), a root canal sealer composed of polydimethylsiloxane, gutta-percha particles, and bioactive glass ceramics, has been developed, to enhance the sealing ability of root canal filling material. The objective of this study was to assess the sealing ability of GB using a subnanoliter-scaled fluid-flow measuring device and to compare with that of AH Plus (AH). The fluid flow in root canal-filled teeth using either gutta-percha cone (GP) with AH (GAR; n = 10) or GP with GB (GBR; n = 10) and in GP inserted in AH blocks (GA; n = 10) or GP inserted in GB blocks (GB; n = 10) was measured. In addition, fluid flow in sealer blocks of AH (A; n = 10) and GB (B; n = 10), which served as negative controls, was measured. Root canal-filled teeth using GP without any sealer (GR) acted as positive controls (n = 10). The leakage was obtained by calculating the volume of moved water by time (s), after stabilization of the fluid flow was achieved. Statistical analysis was performed using the Kruskal–Wallis test and Mann–Whitney U-test with Bonferroni correction. A p value less than 0.00238 (0.05/21) was considered significantly different. The mean leakages (nL/s) in the groups are as follows: GAR, 0.0958 ± 0.0543; GBR, 0.0223 ± 0.0246; GA, 0.0644 ± 0.0803; GB, 0.0267 ± 0.0182; A, 0.0055 ± 0.0057; B, 0.0052 ± 0.005; and GR, 0.2892 ± 0.3018. The mean leakage in the GBR group was lower than that in the GAR group (p = 0.001), while the mean leakages in the GA and GB groups were not significantly different. GuttaFlow bioseal can be useful in single-cone obturation technique.

Lower Premolar

Materials utilizing dentin adhesive technology were developed to provide more effective seal of a root canal. The combined use of new bondable root filling materials and self-adhesive sealers may increase the fracture resistance of filled canals. The null hypothesis of a positive influence on tooth biomechanics by a modern root canal filling material was tested in this study. In order to determine the strength characteristics of the analyzed endodontically treated human tooth the FEM (finite element method) was applied. Lower premolar was used to create a three dimensional model. Its canal was obturated using vertical compaction technique, gutta-percha and resin sealer, access opening was filled with composite resins. Strain analysis of the several elements of the tooth restoration does not allow attributing positive influence of contemporary obturating materials on mechanical properties of root canal dentin. Hypothetically, such an influence would have a filling material with comparable to dentin modulus of elasticity and flexural strength. It was also stated that loading the tooth with 250 N had an effect on increasing the tensions on the interface between filling material – sealer – canal wall. The stresses exceeded 4 MPa, reaching in extreme areas 10 MPa, what practically outweigh adhesion strength of modern root canal sealers. This phenomenon may provoke detachment of a filling from canal walls and therefore led to bacterial leakage. Results of this biomechanical analysis of the endodontically treated human premolar are valuable for a proper evaluation of mechanical properties of modern endodontic filling materials.
